fix(e2e): add Authorization header to API calls in gaps and webkit specs

- Add getStoredAuthHeader helper that reads charon_auth_token from
  localStorage and constructs an Authorization: Bearer header
- Apply the header to all page.request.* API calls in readImportStatus
  and issuePendingSessionCancel
- The previous code relied on the browser cookie jar for these cleanup
  API calls; with Secure=true on auth cookies, browsers refuse to send
  cookies over HTTP to 127.0.0.1 (IP address, not localhost hostname)
  causing silent 401s that left pending ImportSession rows in the DB
- Unreleased sessions caused all subsequent caddy-import tests to show
  the pending-session banner instead of the Caddyfile textarea, failing
  every test after the first
- The fix mirrors how the React app authenticates: via Authorization
  header, which is transport-independent and works on both HTTP and HTTPS

+# Instructions: Maintaining `SECURITY.md`
+
+`SECURITY.md` is the project's living security record. It serves two audiences simultaneously: users who need to know what risks exist right now, and the broader community who need confidence that vulnerabilities are being tracked and remediated with discipline. Treat it like a changelog, but for security events — every known issue gets an entry, every resolved issue keeps its entry.
+
+---
+
+## File Structure
+
+`SECURITY.md` must always contain the following top-level sections, in this order:
+
+1. A brief project security policy preamble (responsible disclosure contact, response SLA)
+2. **`## Known Vulnerabilities`** — active, unpatched issues
+3. **`## Patched Vulnerabilities`** — resolved issues, retained permanently for audit trail
+
+No other top-level sections are required. Do not collapse or remove sections even when they are empty — use the explicit empty-state placeholder defined below.
+
+---
+
+## Section 1: Known Vulnerabilities
+
+This section lists every vulnerability that is currently unpatched or only partially mitigated. Entries must be sorted with the highest severity first, then by discovery date descending within the same severity tier.
+
+### Entry Format
+
+Each entry is an H3 heading followed by a structured block:
+
+```markdown
+### [SEVERITY] CVE-XXXX-XXXXX · Short Title
+
+| Field        | Value |
+|--------------|-------|
+| **ID**       | CVE-XXXX-XXXXX (or `CHARON-YYYY-NNN` if no CVE assigned yet) |
+| **Severity** | Critical / High / Medium / Low · CVSS v3.1 score if known (e.g. `8.1 · High`) |
+| **Status**   | Investigating / Fix In Progress / Awaiting Upstream / Mitigated (partial) |
+
+**What**
+One to three sentences describing the vulnerability class and its impact.
+Be specific: name the weakness type (e.g. SQL injection, path traversal, SSRF).
+
+**Who**
+- Discovered by: [Reporter name or handle, or "Internal audit", or "Automated scan (tool name)"]
+- Reported: YYYY-MM-DD
+- Affects: [User roles, API consumers, unauthenticated users, etc.]
+
+**Where**
+- Component: [Module or service name]
+- File(s): `path/to/affected/file.go`, `path/to/other/file.ts`
+- Versions affected: `>= X.Y.Z` (or "all versions" / "prior to X.Y.Z")
+
+**When**
+- Discovered: YYYY-MM-DD
+- Disclosed (if public): YYYY-MM-DD (or "Not yet publicly disclosed")
+- Target fix: YYYY-MM-DD (or sprint/milestone reference)
+
+**How**
+A concise technical description of the attack vector, prerequisites, and exploitation
+method. Omit proof-of-concept code. Reference CVE advisories or upstream issue
+trackers where appropriate.
+
+**Planned Remediation**
+Describe the fix strategy: library upgrade, logic refactor, config change, etc.
+If a workaround is available in the meantime, document it here.
+Link to the tracking issue: [#NNN](https://github.com/owner/repo/issues/NNN)
+```
+
+### Empty State
+
+When there are no known vulnerabilities:
+
+```markdown
+## Known Vulnerabilities
+
+No known unpatched vulnerabilities at this time.
+Last reviewed: YYYY-MM-DD
+```
+
+---
+
+## Section 2: Patched Vulnerabilities
+
+This section is a permanent, append-only ledger. Entries are never deleted. Sort newest-patched first. This section builds community trust by demonstrating that issues are resolved promptly and transparently.
+
+### Entry Format
+
+```markdown
+### ✅ [SEVERITY] CVE-XXXX-XXXXX · Short Title
+
+| Field        | Value |
+|--------------|-------|
+| **ID**       | CVE-XXXX-XXXXX (or internal ID) |
+| **Severity** | Critical / High / Medium / Low · CVSS v3.1 score |
+| **Patched**  | YYYY-MM-DD in `vX.Y.Z` |
+
+**What**
+Same description carried over from the Known Vulnerabilities entry.
+
+**Who**
+- Discovered by: [Reporter or method]
+- Reported: YYYY-MM-DD
+
+**Where**
+- Component: [Module or service name]
+- File(s): `path/to/affected/file.go`
+- Versions affected: `< X.Y.Z`
+
+**When**
+- Discovered: YYYY-MM-DD
+- Patched: YYYY-MM-DD
+- Time to patch: N days
+
+**How**
+Same technical description as the original entry.
+
+**Resolution**
+Describe exactly what was changed to fix the issue.
+- Commit: [`abc1234`](https://github.com/owner/repo/commit/abc1234)
+- PR: [#NNN](https://github.com/owner/repo/pull/NNN)
+- Release: [`vX.Y.Z`](https://github.com/owner/repo/releases/tag/vX.Y.Z)
+
+**Credit**
+[Optional] Thank the reporter if they consented to attribution.
+```
+
+### Empty State
+
+```markdown
+## Patched Vulnerabilities
+
+No patched vulnerabilities on record yet.
+```
+
+---
+
+## Lifecycle: Moving an Entry from Known → Patched
+
+When a fix ships:
+
+1. Remove the entry from `## Known Vulnerabilities` entirely.
+2. Add a new entry to the **top** of `## Patched Vulnerabilities` using the patched format above.
+3. Carry forward all original fields verbatim — do not rewrite the history of the issue.
+4. Add the `**Resolution**` and `**Credit**` blocks with patch details.
+5. Update the `Last reviewed` date on the Known Vulnerabilities section if it is now empty.
+
+Do not edit or backfill existing Patched entries once they are committed.
+
+---
+
+## Severity Classification
+
+Use the following definitions consistently:
+
+| Severity | CVSS Range | Meaning |
+|----------|------------|---------|
+| **Critical** | 9.0–10.0 | Remote code execution, auth bypass, full data exposure |
+| **High**     | 7.0–8.9  | Significant data exposure, privilege escalation, DoS |
+| **Medium**   | 4.0–6.9  | Limited data exposure, requires user interaction or auth |
+| **Low**      | 0.1–3.9  | Minimal impact, difficult to exploit, defense-in-depth |
+
+When a CVE CVSS score is not yet available, assign a preliminary severity based on these definitions and note it as `(preliminary)` until confirmed.
+
+---
+
+## Internal IDs
+
+If a vulnerability has no CVE assigned, use the format `CHARON-YYYY-NNN` where `YYYY` is the year and `NNN` is a zero-padded sequence number starting at `001` for each year. Example: `CHARON-2025-003`. Assign a CVE ID in the entry retroactively if one is issued later, and add the internal ID as an alias in parentheses.
+
+---
+
+## Responsible Disclosure Preamble
+
+The preamble at the top of `SECURITY.md` (before the vulnerability sections) must include:
+
+- The preferred contact method for reporting vulnerabilities (e.g. a GitHub private advisory link, a security email address, or both)
+- An acknowledgment-first response commitment: confirm receipt within 48 hours, even if the full investigation takes longer
+- A statement that reporters will not be penalized or publicly named without consent
+- A link to the full disclosure policy if one exists
+
+Example:
+
+```markdown
+## Reporting a Vulnerability
+
+To report a security issue, please use
+[GitHub Private Security Advisories](https://github.com/owner/repo/security/advisories/new)
+or email `security@example.com`.
+
+We will acknowledge your report within **48 hours** and provide a remediation
+timeline within **7 days**. Reporters are credited with their consent.
+We do not pursue legal action against good-faith security researchers.
+```
+
+---
+
+## Maintenance Rules
+
+- **Review cadence**: Update the `Last reviewed` date in the Known Vulnerabilities section at least once per release cycle, even if no entries changed.
+- **No silent patches**: Every security fix — no matter how minor — must produce an entry in `## Patched Vulnerabilities` before or alongside the release.
+- **No redaction**: Do not redact or soften historical entries. Accuracy builds trust; minimizing past issues destroys it.
+- **Dependency vulnerabilities**: Transitive dependency CVEs that affect Charon's exposed attack surface must be tracked here the same as first-party vulnerabilities. Pure dev-dependency CVEs with no runtime impact may be omitted at maintainer discretion, but must still be noted in the relevant dependency update PR.
+- **Partial mitigations**: If a workaround is deployed but the root cause is not fixed, the entry stays in `## Known Vulnerabilities` with `Status: Mitigated (partial)` and the workaround documented in `**Planned Remediation**`.

-  # CVE-2026-22184: zlib Global Buffer Overflow in untgz utility
-  # Severity: CRITICAL
-  # Package: zlib 1.3.1-r2 (Alpine Linux base image)
-  # Status: No upstream fix available as of 2026-01-16
-  #
-  # Vulnerability Details:
-  # - Global buffer overflow in TGZfname() function
-  # - Unbounded strcpy() allows attacker-controlled archive names
-  # - Can lead to memory corruption, DoS, potential RCE
-  #
-  # Risk Assessment: ACCEPTED (Low exploitability in Charon context)
-  # - Charon does not use untgz utility directly
-  # - No untrusted tar archive processing in application code
-  # - Attack surface limited to OS-level utilities
-  # - Multiple layers of containerization and isolation
-  #
-  # Mitigation:
-  # - Monitor Alpine Linux security feed daily for zlib patches
-  # - Container runs with minimal privileges (no-new-privileges)
-  # - Read-only filesystem where possible
-  # - Network isolation via Docker networks
-  #
-  # Review:
-  # - Daily checks for Alpine security updates
-  # - Automatic re-scan via CI/CD on every commit
-  # - Manual review scheduled for 2026-01-23 (7 days)
-  #
-  # Removal Criteria:
-  # - Alpine releases zlib 1.3.1-r3 or higher with CVE fix
-  # - OR upstream zlib project releases patched version
-  # - Remove this suppression immediately after fix available
-  #

-    reason: |
-      CRITICAL buffer overflow in untgz utility. No fix available from Alpine
-      as of 2026-01-16. Risk accepted: Charon does not directly use untgz or
-      process untrusted tar archives. Attack surface limited to base OS utilities.
-      Monitoring Alpine security feed for upstream patch.
-    expiry: "2026-03-14"  # Re-evaluate in 7 days

+  # CVE-2026-2673: OpenSSL TLS 1.3 server key exchange group downgrade
+  # Severity: HIGH (CVSS 7.5)
+  # Packages: libcrypto3 3.5.5-r0 and libssl3 3.5.5-r0 (Alpine apk)
+  # Status: No upstream fix available — Alpine 3.23 still ships libcrypto3/libssl3 3.5.5-r0 as of 2026-03-18
+  #
+  # Vulnerability Details:
+  # - When DEFAULT is in the TLS 1.3 group configuration, the OpenSSL server may select
+  #   a weaker key exchange group than preferred, enabling a limited key exchange downgrade.
+  # - Only affects systems acting as a raw TLS 1.3 server using OpenSSL's server-side group negotiation.
+  #
+  # Root Cause (No Fix Available):
+  # - Alpine upstream has not published a patched libcrypto3/libssl3 for Alpine 3.23.
+  # - Checked: Alpine 3.23 still ships libcrypto3/libssl3 3.5.5-r0 as of 2026-03-18.
+  # - Fix path: once Alpine publishes a patched libcrypto3/libssl3, rebuild the Docker image
+  #   and remove this suppression.
+  #
+  # Risk Assessment: ACCEPTED (No upstream fix; limited exposure in Charon context)
+  # - Charon terminates TLS at the Caddy layer — the Go backend does not act as a raw TLS 1.3 server.
+  # - The vulnerability requires the affected application to directly configure TLS 1.3 server
+  #   group negotiation via OpenSSL, which Charon does not do.
+  # - Container-level isolation reduces the attack surface further.
+  #
+  # Mitigation (active while suppression is in effect):
+  # - Monitor Alpine security advisories: https://security.alpinelinux.org/vuln/CVE-2026-2673

+  # Status: Fix available at v1.79.3 — waiting on CrowdSec upstream to release with patched grpc
+  #
+  # Vulnerability Details:
+  # - gRPC-Go server path-based authorization (grpc/authz) fails to match deny rules when
+  #   the HTTP/2 :path pseudo-header is missing its leading slash (e.g., "Service/Method"
+  #   instead of "/Service/Method"), allowing a fallback allow-rule to grant access instead.
+  # - CVSSv3: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
+  #
+  # Root Cause (Third-Party Binary):
+  # - Charon's own grpc dependency is patched to v1.79.3 (updated 2026-03-19).
+  # - CrowdSec ships grpc v1.74.2 compiled into its binary; Charon has no control over this.
+  # - This is a server-side vulnerability. CrowdSec uses grpc as a server; Charon uses it
+  #   only as a client (via the Docker SDK). CrowdSec's internal grpc server is not exposed
+  #   to external traffic in a standard Charon deployment.
+  # - Fix path: once CrowdSec releases a version built with grpc >= v1.79.3, rebuild the
+  #   Docker image (Renovate tracks the CrowdSec version) and remove this suppression.
+  #
+  # Risk Assessment: ACCEPTED (Constrained exploitability in Charon context)
+  # - The vulnerable code path requires an attacker to reach CrowdSec's internal grpc server,
+  #   which is bound to localhost/internal interfaces in the Charon container network.
+  # - Container-level isolation (no exposed grpc port) significantly limits exposure.
+  # - Charon does not configure grpc/authz deny rules on CrowdSec's server.

+  # GHSA-x6gf-mpr2-68h6 / CVE-2026-4427: pgproto3/v2 DataRow.Decode panic on negative field length (DoS)
+  # Severity: HIGH (CVSS 7.5)
+  # Package: github.com/jackc/pgproto3/v2 v2.3.3 (embedded in /usr/local/bin/crowdsec and /usr/local/bin/cscli)
+  # Status: NO fix in pgproto3/v2 (archived/EOL) — fix path requires CrowdSec to migrate to pgx/v5
+  # Note: This is the NVD/Red Hat advisory alias for the same underlying vulnerability as GHSA-jqcq-xjh3-6g23
+  #
+  # Vulnerability Details:
+  # - DataRow.Decode does not validate field lengths; a malicious or compromised PostgreSQL server
+  #   can send a negative field length causing a slice-bounds panic — denial of service (CWE-129).
+  # - CVSSv3: AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H (CVSS 7.5)
+  #
+  # Root Cause (EOL Module + Third-Party Binary):
+  # - Same underlying vulnerability as GHSA-jqcq-xjh3-6g23; tracked separately by NVD/Red Hat as CVE-2026-4427.
+  # - Charon does not use pgproto3/v2 directly nor communicate with PostgreSQL. The package
+  #   is compiled into CrowdSec binaries for their internal database communication.
+  # - The pgproto3/v2 module is archived and EOL; no fix will be released. The fix path
+  #   is migration to pgx/v5, which embeds an updated pgproto3/v3.
+  # - Fix path: once CrowdSec migrates to pgx/v5 and releases an updated binary, rebuild
+  #   the Docker image and remove this suppression.
+  #
+  # Risk Assessment: ACCEPTED (Non-exploitable in Charon context + no upstream fix path)
+  # - The vulnerability requires a malicious PostgreSQL server response. Charon uses SQLite
+  #   internally and does not run PostgreSQL. CrowdSec's database path is not exposed to
+  #   external traffic in a standard Charon deployment.
+  # - The attack requires a compromised database server, which would imply full host compromise.
+  #
+  # Mitigation (active while suppression is in effect):
+  # - Monitor CrowdSec releases for pgx/v5 migration:
+  #   https://github.com/crowdsecurity/crowdsec/releases
+  # - Weekly CI security rebuild flags the moment a fixed image ships.
+  #
+  # Review:
+  # - Reviewed 2026-03-21 (initial suppression): pgproto3/v2 is EOL; no fix exists or will exist.
+  #   Waiting on CrowdSec to migrate to pgx/v5. Set 30-day review. Sibling GHSA-jqcq-xjh3-6g23
+  #   was already suppressed; this alias surfaced as a separate Grype match via NVD/Red Hat tracking.
+  # - Next review: 2026-04-21. Remove suppression once CrowdSec ships with pgx/v5.
+  #
+  # Removal Criteria:
+  # - Same as GHSA-jqcq-xjh3-6g23: CrowdSec releases a version with pgx/v5 replacing pgproto3/v2
+  # - Rebuild Docker image, run security-scan-docker-image, confirm both advisories are resolved
+  # - Remove this entry, GHSA-jqcq-xjh3-6g23 entry, and both .trivyignore entries simultaneously

 ### Fixed
+- **TCP Monitor Creation**: Fixed misleading form UX that caused silent HTTP 500 errors when creating TCP monitors
+  - Corrected URL placeholder to show `host:port` format instead of the incorrect `tcp://host:port` prefix
+  - Added dynamic per-type placeholder and helper text (HTTP monitors show a full URL example; TCP monitors show `host:port`)
+  - Added client-side validation that blocks form submission when a scheme prefix (e.g. `tcp://`) is detected, with an inline error message
+  - Reordered form fields so the monitor type selector appears above the URL input, making the dynamic helper text immediately relevant
+  - i18n: Added 5 new translation keys across en, de, fr, es, and zh locales
+- **CI: Rate Limit Integration Tests**: Hardened test script reliability — login now validates HTTP status, Caddy admin API readiness gated on `/config/` poll, security config failures are fatal with full diagnostics, and poll interval increased to 5s
+- **CI: Rate Limit Integration Tests**: Removed stale GeoIP database SHA256 checksum from Dockerfile non-CI path (hash was perpetually stale due to weekly upstream updates)
+- **CI: Rate Limit Integration Tests**: Fixed Caddy admin API debug dump URL to use canonical trailing slash in workflow
 - Fixed: Added robust validation and debug logging for Docker image tags to prevent invalid reference errors.
 - Fixed: Removed log masking for image references and added manifest validation to debug CI failures.
 - **Proxy Hosts**: Fixed ACL and Security Headers dropdown selections so create/edit saves now keep the selected values (including clearing to none) after submit and reload.

+| **Severity** | High · 7.5 |
+| **Status**   | Awaiting Upstream |
+
+**What**
+An OpenSSL TLS 1.3 server may fail to negotiate the intended key exchange group when the
+configuration includes the `DEFAULT` keyword, potentially allowing downgrade to weaker cipher
+suites. Affects Alpine 3.23.3 packages `libcrypto3` and `libssl3` at version 3.5.5-r0.

+**Who**
+- Discovered by: Automated scan (Grype)
+- Reported: 2026-03-20
+- Affects: Container runtime environment; Caddy reverse proxy TLS negotiation could be affected
+  if default key group configuration is used
+
+**Where**
+- Component: Alpine 3.23.3 base image (`libcrypto3` 3.5.5-r0, `libssl3` 3.5.5-r0)
+- Versions affected: Alpine 3.23.3 prior to a patched `openssl` APK release

+- Discovered: 2026-03-20
+- Disclosed (if public): 2026-03-13 (OpenSSL advisory)
+- Target fix: When Alpine Security publishes a patched `openssl` APK
+
+**How**
+When an OpenSSL TLS 1.3 server configuration uses the `DEFAULT` keyword for key exchange groups,
+the negotiation logic may select a weaker group than intended. Charon's Caddy TLS configuration
+does not use the `DEFAULT` keyword, which limits practical exploitability. The packages are
+present in the base image regardless of Caddy's configuration.
+
+**Planned Remediation**

+
+| Field        | Value |
+|--------------|-------|
+| **ID**       | CHARON-2025-001 (aliases: CVE-2025-58183, CVE-2025-58186, CVE-2025-58187, CVE-2025-61729, CVE-2026-25679, CVE-2025-61732, CVE-2026-27142, CVE-2026-27139) |
+| **Severity** | High · (preliminary, CVSS scores pending upstream confirmation) |
+| **Status**   | Awaiting Upstream |
+
+**What**
+Multiple CVEs in Go standard library packages continue to accumulate in CrowdSec binaries bundled
+with Charon. The cluster originated when CrowdSec was compiled against Go 1.25.1; subsequent
+CrowdSec updates advanced the toolchain to Go 1.25.6/1.25.7, resolving earlier CVEs but
+introducing new ones. The cluster now includes a Critical-severity finding (CVE-2025-68121,
+tracked separately above). All issues resolve when CrowdSec is rebuilt against Go ≥ 1.26.2.
+Charon's own application code is unaffected.
+
+**Who**
+- Discovered by: Automated scan (Trivy, Grype)
+- Reported: 2025-12-01 (original cluster); expanded 2026-03-20
+- Affects: CrowdSec Agent component within the container; not directly exposed through Charon's
+  primary application interface
+
+**Where**
+- Component: CrowdSec Agent (bundled `cscli` and `crowdsec` binaries)
+- Versions affected: All Charon versions shipping CrowdSec binaries compiled against Go < 1.26.2
+
+**When**
+- Discovered: 2025-12-01
+- Disclosed (if public): Not yet publicly disclosed
+- Target fix: When `golang:1.26.2-alpine` is published on Docker Hub
+
+**How**
+The CVEs reside entirely within CrowdSec's compiled binaries and cover HTTP/2, TLS, and archive
+processing paths that are not invoked by Charon's core application logic. The relevant network
+interfaces are not externally exposed via Charon's API surface.
+
+**Planned Remediation**
+`golang:1.26.2-alpine` is not yet available on Docker Hub. The `GO_VERSION` ARG has been
+reverted to `1.26.1` (the latest published image) until `1.26.2` is released. Once available,
+bumping `GO_VERSION` to `1.26.2` and rebuilding the image will resolve the entire alias cluster.
+CVE-2025-68121 (Critical severity, same root cause) is tracked separately above.

+| **Severity** | Medium · 5.5 (NVD) / 2.9 (MITRE) |
+| **Status**   | Awaiting Upstream |
+
+**What**
+zlib before 1.3.2 allows unbounded CPU consumption (denial of service) via the `crc32_combine64`
+and `crc32_combine_gen64` functions. An internal helper `x2nmodp` performs right-shifts inside a
+loop with no termination condition when given a specially crafted input, causing a CPU spin
+(CWE-1284).
+
+**Who**
+- Discovered by: 7aSecurity audit (commissioned by OSTIF)
+- Reported: 2026-02-17
+- Affects: Any component in the container that calls `crc32_combine`-family functions with
+  attacker-controlled input; not directly exposed through Charon's application interface
+
+**Where**
+- Component: Alpine 3.23.3 base image (`zlib` package, version 1.3.1-r2)
+- Versions affected: zlib < 1.3.2; all current Charon images using Alpine 3.23.3
+
+**When**
+- Discovered: 2026-02-17 (NVD published 2026-02-17)
+- Disclosed (if public): 2026-02-17
+- Target fix: When Alpine 3.23 publishes a patched `zlib` APK (requires zlib 1.3.2)
+
+**How**
+Exploitation requires local access (CVSS vector `AV:L`) and the ability to pass a crafted value
+to the `crc32_combine`-family functions. This code path is not invoked by Charon's reverse proxy
+or backend API. The vulnerability is non-blocking under the project's CI severity policy.
+
+**Planned Remediation**
+Monitor https://security.alpinelinux.org/vuln/CVE-2026-27171 for a patched Alpine APK. Once
+available, update the pinned `ALPINE_IMAGE` digest in the Dockerfile, or add an explicit
+`RUN apk upgrade --no-cache zlib` to the runtime stage. Remove the `.trivyignore` entry at
+that time.

+| **ID**       | CHARON-2026-001 (aliases: CVE-2026-0861, CVE-2025-15281, CVE-2026-0915, CVE-2025-13151, and 2 libtiff HIGH CVEs) |
+| **Severity** | High · 8.4 (highest per CVSS v3.1) |
+| **Patched**  | 2026-03-20 (Alpine base image migration complete) |
+
+**What**
+Seven HIGH-severity CVEs in Debian Trixie base image system libraries (`glibc`, `libtasn1-6`,
+`libtiff`). These vulnerabilities resided in the container's OS-level packages with no fixes
+available from the Debian Security Team.
+
+**Who**
+- Discovered by: Automated scan (Trivy)
+- Reported: 2026-02-04
+
+**Where**
+- Component: Debian Trixie base image (`libc6`, `libc-bin`, `libtasn1-6`, `libtiff`)
+- Versions affected: Charon container images built on Debian Trixie base (prior to Alpine migration)
+
+**When**
+- Discovered: 2026-02-04
+- Patched: 2026-03-20
+- Time to patch: 44 days
+
+**How**
+The affected packages were OS-level shared libraries bundled in the Debian Trixie container base
+image. Exploitation would have required local container access or a prior application-level
+compromise. Caddy reverse proxy ingress filtering and container isolation significantly reduced
+the effective attack surface throughout the exposure window.
+
+**Resolution**
+Reverted to Alpine Linux base image (Alpine 3.23.3). Alpine's patch of CVE-2025-60876 (busybox
+heap overflow) removed the original blocker for the Alpine migration. Post-migration scan
+confirmed zero HIGH/CRITICAL CVEs from this cluster.

+| **Severity** | High · 7.5 |
+| **Patched**  | 2026-01-11 |
+
+**What**
+Regular Expression Denial of Service (ReDoS) vulnerability in the `expr-lang/expr` library used
+by CrowdSec for expression evaluation. Malicious regular expressions in CrowdSec scenarios or
+parsers could cause CPU exhaustion and service degradation through exponential backtracking.
+
+**Who**
+- Discovered by: Automated scan (Trivy)
+- Reported: 2026-01-11
+
+**Where**
+- Component: CrowdSec (via `expr-lang/expr` dependency)
+- Versions affected: CrowdSec versions using `expr-lang/expr` < v1.17.7
+
+**When**
+- Discovered: 2026-01-11
+- Patched: 2026-01-11
+- Time to patch: 0 days
+
+**How**
+Maliciously crafted regular expressions in CrowdSec scenario or parser rules could trigger
+exponential backtracking in `expr-lang/expr`'s evaluation engine, causing CPU exhaustion and
+denial of service. The vulnerability is in the upstream expression evaluation library, not in
+Charon's own code.
+
+**Resolution**
+Upgraded CrowdSec to build from source with the patched `expr-lang/expr` v1.17.7. Verification
+confirmed via `go version -m ./cscli` showing the patched library version in compiled artifacts.
+Post-patch Trivy scan reports 0 HIGH/CRITICAL vulnerabilities in application code.

+## Supply Chain Security
+
+Charon implements comprehensive supply chain security measures to ensure the integrity and
+authenticity of releases. Every release includes cryptographic signatures, SLSA provenance
+attestation, and a Software Bill of Materials (SBOM).
+
+### Verification Commands
+
+#### Verify Container Image Signature
+
+All official Charon images are signed with Sigstore Cosign:
+
+```bash
+cosign verify \
+  --certificate-identity-regexp='https://github.com/Wikid82/charon' \
+  --certificate-oidc-issuer='https://token.actions.githubusercontent.com' \
+  ghcr.io/wikid82/charon:latest
+```
+
+Successful verification confirms the image was built by GitHub Actions from the official
+repository and has not been tampered with since signing.
+
+#### Verify SLSA Provenance
+
+```bash
+# Download provenance from release assets
+curl -LO https://github.com/Wikid82/charon/releases/latest/download/provenance.json
+
+slsa-verifier verify-artifact \
+  --provenance-path provenance.json \
+  --source-uri github.com/Wikid82/charon \
+  ./backend/charon-binary
+```
+
+#### Inspect the SBOM
+
+```bash
+# Download SBOM from release assets
+curl -LO https://github.com/Wikid82/charon/releases/latest/download/sbom.spdx.json
+
+# Scan for known vulnerabilities
+grype sbom:sbom.spdx.json
+```
+
+### Transparency Log (Rekor)
+
+All signatures are recorded in the public Sigstore Rekor transparency log:
+<https://search.sigstore.dev/>
+
+### Digest Pinning Policy
+
+**Scope (Required):**
+
+- CI workflows: `.github/workflows/*.yml`
+- CI compose files: `.docker/compose/*.yml`
+- CI helper actions with container refs: `.github/actions/**/*.yml`
+
+CI workflows and CI compose files MUST use digest-pinned images for third-party services.
+Tag+digest pairs are preferred for human-readable references with immutable resolution.
+Self-built images MUST propagate digests to downstream jobs and tests.
+
+**Local Development Exceptions:**
+
+Local-only overrides (e.g., `CHARON_E2E_IMAGE`, `CHARON_IMAGE`, `CHARON_DEV_IMAGE`) MAY use tags
+for developer iteration. Tag-only overrides MUST NOT be used in CI contexts.
+
+**Documented Exceptions & Compensating Controls:**
+
+1. **Go toolchain shim** (`golang.org/dl/goX.Y.Z@latest`) — Uses `@latest` to install the shim;
+   compensated by the target toolchain version being pinned in `go.work` with Renovate tracking.
+2. **Unpinnable dependencies** — Require documented justification; prefer vendor checksums or
+   signed releases; keep SBOM/vulnerability scans in CI.

+## Security Audits & Scanning
+
+### Automated Scanning
+
+| Tool | Purpose |
+|------|---------|
+| Trivy | Container image vulnerability scanning |
+| CodeQL | Static analysis for Go and JavaScript |
+| govulncheck | Go module vulnerability scanning |
+| golangci-lint (gosec) | Go code linting |
+| npm audit | Frontend dependency scanning |
+
+### Scanning Workflows
+
+**Docker Build & Scan** (`.github/workflows/docker-build.yml`) — runs on every commit to `main`,
+`development`, and `feature/beta-release`, and on all PRs targeting those branches. Performs Trivy
+scanning, generates an SBOM, creates SBOM attestations, and uploads SARIF results to the GitHub
+Security tab.
+
+**Supply Chain Verification** (`.github/workflows/supply-chain-verify.yml`) — triggers
+automatically via `workflow_run` after a successful docker-build. Runs SBOM completeness checks,
+Grype vulnerability scans, and (on releases) Cosign signature and SLSA provenance validation.
+
+**Weekly Security Rebuild** (`.github/workflows/security-weekly-rebuild.yml`) — runs every Sunday
+at 02:00 UTC. Performs a full no-cache rebuild, scans for all severity levels, and retains JSON
+artifacts for 90 days.
+
+**PR-Specific Scanning** — extracts and scans only the Charon application binary on each pull
+request. Fails the PR if CRITICAL or HIGH vulnerabilities are found in application code.

-## Supply Chain Security
-
-Charon implements comprehensive supply chain security measures to ensure the integrity and authenticity of releases. Every release includes cryptographic signatures, SLSA provenance attestation, and Software Bill of Materials (SBOM).
-
-### Verification Commands
-
-#### Verify Container Image Signature
-
-All official Charon images are signed with Sigstore Cosign:
-
-```bash
-# Install cosign (if not already installed)
-curl -LO https://github.com/sigstore/cosign/releases/latest/download/cosign-linux-amd64
-sudo mv cosign-linux-amd64 /usr/local/bin/cosign
-sudo chmod +x /usr/local/bin/cosign
-
-# Verify image signature
-cosign verify \
-  --certificate-identity-regexp='https://github.com/Wikid82/charon' \
-  --certificate-oidc-issuer='https://token.actions.githubusercontent.com' \
-  ghcr.io/wikid82/charon:latest
-```
-
-Successful verification output confirms:
-
-- The image was built by GitHub Actions
-- The build came from the official Charon repository
-- The image has not been tampered with since signing
-
-#### Verify SLSA Provenance
-
-SLSA (Supply-chain Levels for Software Artifacts) provenance provides tamper-proof evidence of how the software was built:
-
-```bash
-# Install slsa-verifier (if not already installed)
-curl -LO https://github.com/slsa-framework/slsa-verifier/releases/latest/download/slsa-verifier-linux-amd64
-sudo mv slsa-verifier-linux-amd64 /usr/local/bin/slsa-verifier
-sudo chmod +x /usr/local/bin/slsa-verifier
-
-# Download provenance from release assets
-curl -LO https://github.com/Wikid82/charon/releases/latest/download/provenance.json
-
-# Verify provenance
-slsa-verifier verify-artifact \
-  --provenance-path provenance.json \
-  --source-uri github.com/Wikid82/charon \
-  ./backend/charon-binary
-```
-
-#### Inspect Software Bill of Materials (SBOM)
-
-Every release includes a comprehensive SBOM in SPDX format:
-
-```bash
-# Download SBOM from release assets
-curl -LO https://github.com/Wikid82/charon/releases/latest/download/sbom.spdx.json
-
-# View SBOM contents
-cat sbom.spdx.json | jq .
-
-# Check for known vulnerabilities (requires Grype)
-grype sbom:sbom.spdx.json
-```
-
-### Transparency Log (Rekor)
-
-All signatures are recorded in the public Sigstore Rekor transparency log, providing an immutable audit trail:
-
-- **Search the log**: <https://search.sigstore.dev/>
-- **Query by image**: Search for `ghcr.io/wikid82/charon`
-- **View entry details**: Each entry includes commit SHA, workflow run, and signing timestamp
-
-### Automated Verification in CI/CD
-
-Integrate supply chain verification into your deployment pipeline:
-
-```yaml
-# Example GitHub Actions workflow
-- name: Verify Charon Image
-  run: |
-    cosign verify \
-      --certificate-identity-regexp='https://github.com/Wikid82/charon' \
-      --certificate-oidc-issuer='https://token.actions.githubusercontent.com' \
-      ghcr.io/wikid82/charon:${{ env.VERSION }}
-```
-
-### What's Protected
-
-- **Container Images**: All `ghcr.io/wikid82/charon:*` images are signed
-- **Release Binaries**: Backend binaries include provenance attestation
-- **Build Process**: SLSA Level 3 compliant build provenance
-- **Dependencies**: Complete SBOM including all direct and transitive dependencies
-
-### Digest Pinning Policy
-
-Charon uses digest pinning to reduce supply chain risk and ensure CI runs against immutable artifacts.
-
-**Scope (Required):**
-
-- **CI workflows**: `.github/workflows/*.yml`, `.github/workflows/*.yaml`
-- **CI compose files**: `.docker/compose/*.yml`, `.docker/compose/*.yaml`, `.docker/compose/docker-compose*.yml`, `.docker/compose/docker-compose*.yaml`
-- **CI helper actions with container refs**: `.github/actions/**/*.yml`, `.github/actions/**/*.yaml`
-- CI workflows and CI compose files MUST use digest-pinned images for third-party services.
-- Tag+digest pairs are preferred for human-readable references with immutable resolution.
-- Self-built images MUST propagate digests to downstream jobs and tests.
-
-**Rationale:**
-
-- Prevent tag drift and supply chain substitution in automated runs.
-- Ensure deterministic builds, reproducible scans, and stable SBOM generation.
-- Reduce rollback risk by guaranteeing CI uses immutable artifacts.
-
-**Local Development Exceptions:**
-
-- Local-only overrides (e.g., `CHARON_E2E_IMAGE`, `CHARON_IMAGE`, `CHARON_DEV_IMAGE`) MAY use tags for developer iteration.
-- Tag-only overrides MUST NOT be used in CI contexts.
-
-**Documented Exceptions & Compensating Controls:**
-
-1. **Go toolchain shim** (`golang.org/dl/goX.Y.Z@latest`)
-   - **Exception:** Uses `@latest` to install the shim.
-   - **Compensating controls:** The target toolchain version is pinned in
-     `go.work`, and Renovate tracks the required version for updates.
-
-2. **Unpinnable dependencies** (no stable digest or checksum source)
-   - **Exception:** Dependency cannot be pinned by digest.
-   - **Compensating controls:** Require documented justification, prefer
-     vendor-provided checksums or signed releases when available, and keep
-     SBOM/vulnerability scans in CI.

-## Security Audits & Scanning
-
-### Automated Scanning
-
-We use the following tools:
-
-- **Trivy**: Container image vulnerability scanning
-- **CodeQL**: Static code analysis for Go and JavaScript
-- **govulncheck**: Go module vulnerability scanning
-- **golangci-lint**: Go code linting (including gosec)
-- **npm audit**: Frontend dependency vulnerability scanning
-
-### Security Scanning Workflows
-
-Charon implements multiple layers of automated security scanning:
-
-#### Docker Build & Scan (Per-Commit)
-
-**Workflow**: `.github/workflows/docker-build.yml`
-
-- Runs on every commit to `main`, `development`, and `feature/beta-release` branches
-- Runs on all pull requests targeting these branches
-- Performs Trivy vulnerability scanning on built images
-- Generates SBOM (Software Bill of Materials) for supply chain transparency
-- Creates SBOM attestations for verifiable build provenance
-- Verifies Caddy security patches (CVE-2025-68156)
-- Uploads SARIF results to GitHub Security tab
-
-**Note**: This workflow replaced the previous `docker-publish.yml` (deleted Dec 21, 2025) with enhanced security features.
-
-#### Supply Chain Verification
-
-**Workflow**: `.github/workflows/supply-chain-verify.yml`
-
-**Trigger Timing**: Runs automatically after `docker-build.yml` completes successfully via `workflow_run` trigger.
-
-**Branch Coverage**: Triggers on **ALL branches** where docker-build completes, including:
-
-- `main` (default branch)
-- `development`
-- `feature/*` branches (including `feature/beta-release`)
-- Pull request branches
-
-**Why No Branch Filter**: GitHub Actions has a platform limitation where `branches` filters in `workflow_run` triggers only match the default branch. To ensure comprehensive supply chain verification across all branches and PRs, we intentionally omit the branch filter. The workflow file must exist on the branch to execute, preventing untrusted code execution.
-
-**Verification Steps**:
-
-1. SBOM completeness verification
-2. Vulnerability scanning with Grype
-3. Results uploaded as workflow artifacts
-4. PR comments with vulnerability summary (when applicable)
-5. For releases: Cosign signature verification and SLSA provenance validation
-
-**Additional Triggers**:
-
-- Runs on all published releases
-- Scheduled weekly on Mondays at 00:00 UTC
-- Can be triggered manually via `workflow_dispatch`
-
-#### Weekly Security Rebuild
-
-**Workflow**: `.github/workflows/security-weekly-rebuild.yml`
-
-- Runs every Sunday at 02:00 UTC
-- Performs full rebuild with no cache to ensure latest base images
-- Scans with Trivy for CRITICAL, HIGH, MEDIUM, and LOW vulnerabilities
-- Uploads results to GitHub Security tab
-- Stores JSON artifacts for 90-day retention
-- Checks Alpine package versions for security updates
-
-#### PR-Specific Scanning
-
-**Workflow**: `.github/workflows/docker-build.yml` (trivy-pr-app-only job)
-
-- Runs on all pull requests
-- Extracts and scans only the Charon application binary
-- Fails PR if CRITICAL or HIGH vulnerabilities found in application code
-- Faster feedback loop for developers during code review
-
-### Workflow Orchestration
-
-The security scanning workflows use a coordinated orchestration pattern:
-
-1. **Build Phase**: `docker-build.yml` builds the image and performs initial Trivy scan
-2. **Verification Phase**: `supply-chain-verify.yml` triggers automatically via `workflow_run` after successful build
-3. **Verification Timing**:
-   - On feature branches: Runs after docker-build completes on push events
-   - On pull requests: Runs after docker-build completes on PR synchronize events
-   - No delay or gaps: verification starts immediately after build success
-4. **Weekly Maintenance**: `security-weekly-rebuild.yml` provides ongoing monitoring
-
-This pattern ensures:
-
-- Images are built before verification attempts to scan them
-- No race conditions between build and verification
-- Comprehensive coverage across all branches and PRs
-- Efficient resource usage (verification only runs after successful builds)
-
-### Manual Reviews
-
-- Security code reviews for all major features
-- Peer review of security-sensitive changes
-- Third-party security audits (planned)
-
-### Continuous Monitoring
-
-- GitHub Dependabot alerts
-- Weekly security scans in CI/CD
-- Community vulnerability reports
-- Automated supply chain verification on every build
-

-## Known Security Considerations
-
-### Debian Base Image CVEs (2026-02-04) — TEMPORARY
-
-**Status**: ⚠️ 7 HIGH severity CVEs in Debian Trixie base image. **Alpine migration in progress.**
-
-**Background**: Migrated from Alpine → Debian due to CVE-2025-60876 (busybox heap overflow). Debian now has worse CVE posture with no fixes available. Reverting to Alpine as Alpine CVE-2025-60876 is now patched.
-
-**Affected Packages**:
-- **libc6/libc-bin** (glibc): CVE-2026-0861 (CVSS 8.4), CVE-2025-15281, CVE-2026-0915
-- **libtasn1-6**: CVE-2025-13151 (CVSS 7.5)
-- **libtiff**: 2 additional HIGH CVEs
-
-**Fix Status**: ❌ No fixes available from Debian Security Team
-
-**Risk Assessment**: 🟢 **LOW actual risk**
-- CVEs affect system libraries, NOT Charon application code
-- Container isolation limits exploit surface area
-- No direct exploit paths identified in Charon's usage patterns
-- Network ingress filtered through Caddy proxy
-
-**Mitigation**: Alpine base image migration
-- **Spec**: [`docs/plans/alpine_migration_spec.md`](docs/plans/alpine_migration_spec.md)
-- **Security Advisory**: [`docs/security/advisory_2026-02-04_debian_cves_temporary.md`](docs/security/advisory_2026-02-04_debian_cves_temporary.md)
-- **Timeline**: 2-3 weeks (target completion: March 5, 2026)
-- **Expected Outcome**: 100% CVE reduction (7 HIGH → 0)
-
-**Review Date**: 2026-02-11 (Phase 1 Alpine CVE verification)
-
-**Details**: See [VULNERABILITY_ACCEPTANCE.md](docs/security/VULNERABILITY_ACCEPTANCE.md) for complete risk assessment and monitoring plan.
-
-### Third-Party Dependencies
-
-**CrowdSec Binaries**: As of December 2025, CrowdSec binaries shipped with Charon contain 4 HIGH-severity CVEs in Go stdlib (CVE-2025-58183, CVE-2025-58186, CVE-2025-58187, CVE-2025-61729). These are upstream issues in Go 1.25.1 and will be resolved when CrowdSec releases binaries built with go 1.26.0+.
-
-**Impact**: Low. These vulnerabilities are in CrowdSec's third-party binaries, not in Charon's application code. They affect HTTP/2, TLS certificate handling, and archive parsing—areas not directly exposed to attackers through Charon's interface.
-
-**Mitigation**: Monitor CrowdSec releases for updated binaries. Charon's own application code has zero vulnerabilities.

+### Slack Webhooks
+
+Slack notifications send messages to a channel using an Incoming Webhook URL.
+
+**Setup:**
+
+1. In Slack, go to **[Your Apps](https://api.slack.com/apps)** → **Create New App** → **From scratch**
+2. Under **Features**, select **Incoming Webhooks** and toggle it **on**
+3. Click **"Add New Webhook to Workspace"** and choose the channel to post to
+4. Copy the Webhook URL (it looks like `https://hooks.slack.com/services/T.../B.../...`)
+5. In Charon, go to **Settings** → **Notifications** and click **"Add Provider"**
+6. Select **Slack** as the service type
+7. Paste your Webhook URL into the **Webhook URL** field
+8. Optionally enter a channel display name (e.g., `#alerts`) for easy identification
+9. Configure notification triggers and save
+
+> **Security:** Your Webhook URL is stored securely and is never exposed in API responses. The settings page only shows a `has_token: true` indicator, so your URL stays private even if someone gains read-only access to the API.
+
+#### Basic Message

+}
+```
+
+**Slack formatting tips:**
+
+- Use `*bold*` for emphasis
+- Use `\n` for line breaks
+- Use `•` for bullet points
+- Slack automatically linkifies URLs
+
+### Pushover
+
+Pushover delivers push notifications directly to your iOS, Android, or desktop devices.
+

+### Required Secrets (Generate Before Installing)
+
+Two secrets must be set before starting Charon. Omitting them will cause **sessions to reset on every container restart**, locking users out.
+
+Generate both values now and keep them somewhere safe:
+
+```bash
+# JWT secret — signs and validates login sessions
+openssl rand -hex 32
+
+# Encryption key — protects stored credentials at rest
+openssl rand -base64 32

+# Manual Test Plan - PR-5 TCP Monitor UX Fix
+
+## Scope
+
+PR-5 only.
+
+This plan covers manual verification of the five UX fixes applied to the TCP monitor creation form:
+
+1. Corrected URL placeholder (removed misleading `tcp://` prefix)
+2. Dynamic per-type placeholder (HTTP vs TCP)
+3. Per-type helper text below the URL input
+4. Client-side TCP scheme validation with inline error
+5. Form field reorder: type selector now appears before URL input
+
+Out of scope:
+- Backend monitor logic or storage
+- Any other monitor type beyond HTTP and TCP
+- Notification provider changes
+
+## Preconditions
+
+- [ ] Environment is running (Docker E2E or local dev).
+- [ ] Tester can access the Monitors page and open the Create Monitor modal.
+- [ ] Browser DevTools Network tab is available for TC-PR5-007.
+
+---
+
+## Track A — Smoke Tests (Existing HTTP Behaviour)
+
+### TC-PR5-001 HTTP monitor creation still works
+
+- [ ] Open the Create Monitor modal.
+- [ ] Select type **HTTP**.
+- [ ] Enter a valid URL: `https://example.com`.
+- [ ] Fill in remaining required fields and click **Create**.
+- Expected result: monitor is created successfully; no errors shown.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+### TC-PR5-009 Existing HTTP monitors display correctly in the list
+
+- [ ] Navigate to the Monitors list.
+- [ ] Confirm any pre-existing HTTP monitors are still shown with correct URLs.
+- Expected result: no regressions in list display.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+### TC-PR5-010 Existing TCP monitors display correctly in the list
+
+- [ ] Navigate to the Monitors list.
+- [ ] Confirm any pre-existing TCP monitors are still shown with correct host:port values.
+- Expected result: no regressions in list display.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+---
+
+## Track B — Core Fix (TCP Scheme Validation)
+
+### TC-PR5-002 TCP monitor with `tcp://` prefix shows inline error and blocks submission
+
+- [ ] Open the Create Monitor modal.
+- [ ] Select type **TCP**.
+- [ ] Enter URL: `tcp://192.168.1.1:8080`.
+- [ ] Click **Create** (or attempt to submit).
+- Expected result: an inline error appears on the URL field; the form is not submitted; no new monitor appears in the list.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+### TC-PR5-003 TCP monitor with valid `host:port` format succeeds
+
+- [ ] Open the Create Monitor modal.
+- [ ] Select type **TCP**.
+- [ ] Enter URL: `192.168.1.1:8080`.
+- [ ] Fill in remaining required fields and click **Create**.
+- Expected result: monitor is created successfully; no errors shown.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+---
+
+## Track C — Dynamic Placeholder & Helper Text
+
+### TC-PR5-005 Form field order: Type selector appears above URL input
+
+- [ ] Open the Create Monitor modal.
+- [ ] Inspect the visual layout of the form.
+- Expected result: the monitor **Type** selector is positioned above the **URL** input field.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+### TC-PR5-006 Helper text updates when switching between HTTP and TCP
+
+- [ ] Open the Create Monitor modal.
+- [ ] Select type **HTTP** and note the helper text shown beneath the URL input.
+- [ ] Switch type to **TCP** and note the helper text again.
+- Expected result: helper text differs between HTTP and TCP types, giving format guidance appropriate to each.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+### TC-PR5-006b Placeholder updates when switching between HTTP and TCP
+
+- [ ] Open the Create Monitor modal.
+- [ ] Select type **HTTP** and note the URL input placeholder.
+- [ ] Switch type to **TCP** and note the placeholder again.
+- Expected result: HTTP placeholder shows a full URL (e.g. `https://example.com`); TCP placeholder shows `host:port` format (no scheme).
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+---
+
+## Track D — Interaction Edge Cases
+
+### TC-PR5-004 Switching type from TCP (with error) to HTTP clears the inline error
+
+- [ ] Open the Create Monitor modal.
+- [ ] Select type **TCP** and enter `tcp://192.168.1.1:8080` to trigger the inline error.
+- [ ] Switch type to **HTTP**.
+- Expected result: the scheme-prefix inline error disappears immediately after the type change.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+### TC-PR5-007 Submit guard: no API call fires when scheme prefix error is present
+
+- [ ] Open browser DevTools and go to the **Network** tab.
+- [ ] Open the Create Monitor modal.
+- [ ] Select type **TCP** and enter `tcp://192.168.1.1:8080`.
+- [ ] Click **Create**.
+- Expected result: the inline error is shown and no outbound POST/PUT request to the monitors API endpoint appears in the Network tab.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+---
+
+## Track E — Localisation (Optional)
+
+### TC-PR5-008 New translation keys appear correctly in non-English locales
+
+- [ ] Switch the application language to **German**, **French**, **Spanish**, or **Chinese**.
+- [ ] Open the Create Monitor modal and select type **TCP**.
+- [ ] Observe the URL placeholder, helper text, and inline error message (trigger it with `tcp://host:port`).
+- Expected result: all three UI strings appear in the selected language without showing raw translation key strings (e.g. no `urlPlaceholder.tcp` visible to the user).
+- Status: [ ] Not run [ ] Pass [ ] Fail

+# Manual Testing: Slack Notification Provider
+
+## Description
+
+Manual test plan for the Slack notification provider feature. Covers scenarios that automated E2E tests cannot fully validate, such as real Slack workspace delivery, message formatting, and edge cases around webhook lifecycle.
+
+## Pre-requisites
+
+- A Slack workspace with at least one channel
+- An Incoming Webhook URL created via Slack App configuration (https://api.slack.com/messaging/webhooks)
+- Access to the Charon instance
+
+## Test Cases
+
+### Provider CRUD
+
+- [ ] **Create**: Add a Slack provider with a valid webhook URL and optional channel name (`#alerts`)
+- [ ] **Edit**: Change the channel display name — verify webhook URL is preserved (not cleared)
+- [ ] **Test**: Click "Send Test Notification" — verify message appears in Slack channel
+- [ ] **Delete**: Remove the Slack provider — verify it no longer appears in the list
+- [ ] **Re-create**: Add a new Slack provider after deletion — verify clean state
+
+### Security
+
+- [ ] Webhook URL is NOT visible in the provider list UI (only `has_token: true` indicator)
+- [ ] Webhook URL is NOT returned in GET `/api/v1/notifications/providers` response body
+- [ ] Editing an existing provider does NOT expose the webhook URL in any form field
+- [ ] Browser DevTools Network tab shows no webhook URL in any API response
+
+### Message Delivery
+
+- [ ] Default template sends a readable notification to Slack
+- [ ] Custom JSON template with `text` field renders correctly
+- [ ] Custom JSON template with `blocks` renders Block Kit layout
+- [ ] Notifications triggered by proxy host changes arrive in Slack
+- [ ] Notifications triggered by certificate events arrive in Slack
+- [ ] Notifications triggered by uptime events arrive in Slack (if enabled)
+
+### Error Handling
+
+- [ ] Invalid webhook URL (not matching `hooks.slack.com/services/` pattern) shows validation error
+- [ ] Expired/revoked webhook URL returns `no_service` classification error
+- [ ] Disabled feature flag (`feature.notifications.service.slack.enabled=false`) prevents Slack dispatch
+
+### Edge Cases
+
+- [ ] Creating provider with empty URL field succeeds (URL is optional channel display name)
+- [ ] Very long channel name in URL field is handled gracefully
+- [ ] Multiple Slack providers with different webhooks can coexist
+- [ ] Switching provider type from Slack to Discord clears the token field appropriately
+- [ ] Switching provider type from Discord to Slack shows the webhook URL input field
+
+### Cross-Browser
+
+- [ ] Provider CRUD works in Chrome/Chromium
+- [ ] Provider CRUD works in Firefox
+- [ ] Provider CRUD works in Safari/WebKit
+
+## Acceptance Criteria
+
+- [ ] All security test cases pass — webhook URL never exposed
+- [ ] End-to-end message delivery confirmed in a real Slack workspace
+- [ ] No console errors during any provider operations
+- [ ] Feature flag correctly gates Slack functionality

+# Manual Testing: Vite 8.0.0-beta.18 Upgrade
+
+**Date:** 2026-03-12
+**Status:** Open
+**Priority:** Medium
+**Related Commit:** chore(frontend): upgrade to Vite 8 beta with Rolldown bundler
+
+---
+
+## Context
+
+Vite 8 replaces Rollup with Rolldown (Rust-based bundler) and esbuild with Oxc for
+JS transforms/minification. Lightning CSS replaces esbuild for CSS minification. These
+are fundamental changes to the build pipeline that automated tests may not fully cover.
+
+## Manual Test Cases
+
+### 1. Production Build Output Verification
+
+- [ ] Deploy the Docker image to a staging environment
+- [ ] Verify the application loads without console errors
+- [ ] Verify all CSS renders correctly (Lightning CSS minification change)
+- [ ] Check browser DevTools Network tab — confirm single JS bundle loads
+- [ ] Verify sourcemaps work correctly in browser DevTools
+
+### 2. CJS Interop Regression Check
+
+Vite 8 changes how CommonJS default exports are handled.
+
+- [ ] Verify axios API calls succeed (login, proxy host CRUD, settings)
+- [ ] Verify react-hot-toast notifications render on success/error actions
+- [ ] Verify react-hook-form validation works on all forms
+- [ ] Verify @tanstack/react-query data fetching and caching works
+
+### 3. Dynamic Import / Code Splitting
+
+The `codeSplitting: false` config replaces the old `inlineDynamicImports: true`.
+
+- [ ] Verify lazy-loaded routes load correctly
+- [ ] Verify no "chunk load failed" errors during navigation
+- [ ] Check that the React initialization issue (original reason for the workaround) does not resurface
+
+### 4. Development Server
+
+- [ ] Run `npm run dev` in frontend — verify HMR (Hot Module Replacement) works
+- [ ] Make a CSS change — verify it hot-reloads without full page refresh
+- [ ] Make a React component change — verify it hot-reloads preserving state
+- [ ] Verify the dev server proxy to backend API still works
+
+### 5. Cross-Browser Verification
+
+Test in each browser to catch any Rolldown/Oxc output differences:
+
+- [ ] Chrome/Chromium — full functional test
+- [ ] Firefox — full functional test
+- [ ] Safari/WebKit — full functional test
+
+### 6. Docker Build Verification
+
+- [ ] Build Docker image on the target deployment architecture
+- [ ] Verify the image starts and passes health checks
+- [ ] Verify Rolldown native bindings resolve correctly (no missing .node errors)
+- [ ] Test with `--platform=linux/amd64` explicitly
+
+### 7. Edge Cases
+
+- [ ] Test with browser cache cleared (ensure no stale Vite 7 chunks cached)
+- [ ] Test login flow end-to-end
+- [ ] Test certificate management flows
+- [ ] Test DNS provider configuration
+- [ ] Test access list creation and assignment
+
+## Known Issues to Monitor
+
+1. **Oxc Minifier assumptions** — if runtime errors occur after build but not in dev, the minifier is the likely cause. Disable with `build.minify: false` to diagnose.
+2. **Lightning CSS bundle size** — may differ slightly from esbuild. Compare `dist/assets/` sizes.
+3. **Beta software stability** — track Vite 8 releases for fixes to any issues found.
+
+## Pass Criteria
+
+All checkboxes above must be verified. Any failure should be filed as a separate issue with the `vite-8-beta` label.

+# CI Supply Chain CVE Remediation Plan
+
+**Status:** Active
+**Created:** 2026-03-13
+**Branch:** `feature/beta-release`
+**Context:** Three HIGH vulnerabilities (CVE-2025-69650, CVE-2025-69649, CVE-2026-3805) in the Docker runtime image are blocking the CI supply-chain scan. Two Grype ignore-rule entries are also expired and require maintenance.
+
+---
+
+## 1. Executive Summary
+
+| # | Action | Severity Reduction | Effort |
+|---|--------|--------------------|--------|
+| 1 | Remove `curl` from runtime image (replace with `wget`) | Eliminates 1 HIGH + ~7 MEDIUMs + 2 LOWs | ~30 min |
+| 2 | Remove `binutils` + `libc-utils` from runtime image | Eliminates 2 HIGH + 3 MEDIUMs | ~5 min |
+| 3 | Update expired Grype ignore rules | Prevents false scan failures at next run | ~10 min |
+
+**Bottom line:** All three HIGH CVEs are eliminated at root rather than suppressed. After Phase 1 and Phase 2, `fail-on-severity: high` passes cleanly. Phase 3 is maintenance-only.
+
+---
+
+## 2. CVE Inventory
+
+### Blocking HIGH CVEs
+
+| CVE | Package | Version | CVSS | Fix State | Notes |
+|-----|---------|---------|------|-----------|-------|
+| CVE-2026-3805 | `curl` | 8.17.0-r1 | 7.5 | `unknown` | **New** — appeared in Grype DB 2026-03-13, published 2026-03-11. SMB protocol use-after-free. Charon uses HTTPS/HTTP only. |
+| CVE-2025-69650 | `binutils` | 2.45.1-r0 | 7.5 | `` (none) | Double-free in `readelf`. Charon never invokes `readelf`. |
+| CVE-2025-69649 | `binutils` | 2.45.1-r0 | 7.5 | `` (none) | Null-ptr deref in `readelf`. Charon never invokes `readelf`. |
+
+### Associated MEDIUM/LOW CVEs eliminated as side-effects
+
+| CVEs | Package | Count | Eliminated by |
+|------|---------|-------|---------------|
+| CVE-2025-14819, CVE-2025-15079, CVE-2025-14524, CVE-2025-13034, CVE-2025-14017 | `curl` | 5 × MEDIUM | Phase 1 |
+| CVE-2025-69652, CVE-2025-69644, CVE-2025-69651 | `binutils` | 3 × MEDIUM | Phase 2 |
+
+### Expired Grype Ignore Rules
+
+| Entry | Expiry | Status | Action |
+|-------|--------|--------|--------|
+| `CVE-2026-22184` (zlib) | 2026-03-14 | Expires tomorrow; underlying CVE already fixed via `apk upgrade --no-cache zlib` | **Remove entirely** |
+| `GHSA-69x3-g4r3-p962` (nebula) | 2026-03-05 | **Expired 8 days ago**; upstream fix still unavailable | **Extend to 2026-04-13** |
+
+---
+
+## 3. Phase 1 — Remove `curl` from Runtime Image
+
+### Rationale
+
+`curl` is present solely for:
+1. GeoLite2 DB download at build time (Dockerfile, runtime stage `RUN` block)
+2. HEALTHCHECK probe (Dockerfile `HEALTHCHECK` directive)
+3. Caddy admin API readiness poll (`.docker/docker-entrypoint.sh`)
+
+`busybox` (already installed on Alpine as a transitive dependency of `busybox-extras`, which is explicitly installed) provides `wget` with sufficient functionality for all three uses.
+
+### 3.1 `wget` Translation Reference
+
+| `curl` invocation | `wget` equivalent | Notes |
+|-------------------|--------------------|-------|
+| `curl -fSL -m 10 "URL" -o FILE 2>/dev/null` | `wget -qO FILE -T 10 "URL" 2>/dev/null` | `-q` = quiet; `-T` = timeout (seconds); exits nonzero on failure |
+| `curl -fSL -m 30 --retry 3 "URL" -o FILE` | `wget -qO FILE -T 30 -t 4 "URL"` | `-t 4` = 4 total tries (1 initial + 3 retries); add `&& [ -s FILE ]` guard |
+| `curl -f http://HOST/path \|\| exit 1` | `wget -q -O /dev/null http://HOST/path \|\| exit 1` | HEALTHCHECK; wget exits nonzero on HTTP error |
+| `curl -sf http://HOST/path > /dev/null 2>&1` | `wget -qO /dev/null http://HOST/path 2>/dev/null` | Silent readiness probe |
+
+**busybox wget notes:**
+- `-T N` is per-connection timeout in seconds (equivalent to `curl --max-time`).
+- `-t N` is total number of tries, not retries; `-t 4` = 3 retries.
+- On download failure, busybox wget may leave a zero-byte or partial file at the output path. The `[ -s FILE ]` guard (`-s` = non-empty) prevents a corrupted placeholder from passing the sha256 check.
+
+### 3.2 Dockerfile Changes
+
+**File:** `Dockerfile`
+
+**Change A — Remove `curl`, `binutils`, `libc-utils` from `apk add` (runtime stage, line ~413):**
+
+Current:
+```dockerfile
+RUN apk add --no-cache \
+    bash ca-certificates sqlite-libs sqlite tzdata curl gettext libcap libcap-utils \
+    c-ares binutils libc-utils busybox-extras \
+    && apk upgrade --no-cache zlib
+```
+
+New:
+```dockerfile
+RUN apk add --no-cache \
+    bash ca-certificates sqlite-libs sqlite tzdata gettext libcap libcap-utils \
+    c-ares busybox-extras \
+    && apk upgrade --no-cache zlib
+```
+
+*(This single edit covers both Phase 1 and Phase 2 removals.)*
+
+**Change B — GeoLite2 download block, CI path (line ~437):**
+
+Current:
+```dockerfile
+if curl -fSL -m 10 "https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb" \
+    -o /app/data/geoip/GeoLite2-Country.mmdb 2>/dev/null; then
+```
+
+New:
+```dockerfile
+if wget -qO /app/data/geoip/GeoLite2-Country.mmdb \
+    -T 10 "https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb" 2>/dev/null; then
+```
+
+**Change C — GeoLite2 download block, non-CI path (line ~445):**
+
+Current:
+```dockerfile
+if curl -fSL -m 30 --retry 3 "https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb" \
+    -o /app/data/geoip/GeoLite2-Country.mmdb; then
+    if echo "${GEOLITE2_COUNTRY_SHA256}  /app/data/geoip/GeoLite2-Country.mmdb" | sha256sum -c -; then
+```
+
+New:
+```dockerfile
+if wget -qO /app/data/geoip/GeoLite2-Country.mmdb \
+    -T 30 -t 4 "https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb"; then
+    if [ -s /app/data/geoip/GeoLite2-Country.mmdb ] && \
+       echo "${GEOLITE2_COUNTRY_SHA256}  /app/data/geoip/GeoLite2-Country.mmdb" | sha256sum -c -; then
+```
+
+The `[ -s FILE ]` check is added before `sha256sum` to guard against wget leaving an empty file on partial failure.
+
+**Change D — HEALTHCHECK directive (line ~581):**
+
+Current:
+```dockerfile
+HEALTHCHECK --interval=30s --timeout=3s --start-period=40s --retries=3 \
+    CMD curl -f http://localhost:8080/api/v1/health || exit 1
+```
+
+New:
+```dockerfile
+HEALTHCHECK --interval=30s --timeout=3s --start-period=40s --retries=3 \
+    CMD wget -q -O /dev/null http://localhost:8080/api/v1/health || exit 1
+```
+
+### 3.3 Entrypoint Changes
+
+**File:** `.docker/docker-entrypoint.sh`
+
+**Change E — Caddy readiness poll (line ~368):**
+
+Current:
+```sh
+if curl -sf http://127.0.0.1:2019/config/ > /dev/null 2>&1; then
+```
+
+New:
+```sh
+if wget -qO /dev/null http://127.0.0.1:2019/config/ 2>/dev/null; then
+```
+
+---
+
+## 4. Phase 2 — Remove `binutils` and `libc-utils` from Runtime Image
+
+### Rationale
+
+`binutils` is installed solely for `objdump`, used in `.docker/docker-entrypoint.sh` to detect DWARF debug symbols when `CHARON_DEBUG=1`. The entrypoint already has a graceful fallback (lines ~401–404):
+
+```sh
+else
+    # objdump not available, try to run Delve anyway with a warning
+    echo "Note: Cannot verify debug symbols (objdump not found). Attempting Delve..."
+    run_as_charon /usr/local/bin/dlv exec "$bin_path" ...
+fi
+```
+
+When `objdump` is absent the container functions correctly for all standard and debug-mode runs. The check is advisory.
+
+`libc-utils` appears **only once** across the entire codebase (confirmed by grep across `*.sh`, `Dockerfile`, `*.yml`): as a sibling entry on the same `apk add` line as `binutils`. It provides glibc-compatible headers for musl-based Alpine and has no independent consumer in this image. It is safe to remove together with `binutils`.
+
+### 4.1 Dockerfile Change
+
+Already incorporated in Phase 1 Change A — the `apk add` line removes both `binutils` and `libc-utils` in a single edit. No additional changes are required.
+
+### 4.2 Why Not Suppress Instead?
+
+Suppressing in Grype requires two new ignore entries with expiry maintenance every 30 days indefinitely (no upstream Alpine fix exists). Removing the packages eliminates the CVEs permanently. There is no functional regression given the working fallback.
+
+---
+
+## 5. Phase 3 — Update Expired Grype Ignore Rules
+
+**File:** `.grype.yaml`
+
+### 5.1 Remove `CVE-2026-22184` (zlib) Block
+
+**Action:** Delete the entire `CVE-2026-22184` ignore entry.
+
+**Reason:** The Dockerfile runtime stage already contains `&& apk upgrade --no-cache zlib`, which upgrades zlib from 1.3.1-r2 to 1.3.2-r0, resolving CVE-2026-22184. Suppressing a resolved CVE creates false confidence and obscures scan accuracy. The entry's own removal criteria have been met: Alpine released `zlib 1.3.2-r0`.
+
+### 5.2 Extend `GHSA-69x3-g4r3-p962` (nebula) Expiry
+
+**Action:** Update the `expiry` field and review comment in the nebula block.
+
+Current:
+```yaml
+    expiry: "2026-03-05"  # Re-evaluate in 14 days (2026-02-19 + 14 days)
+```
+
+New:
+```yaml
+    expiry: "2026-04-13"  # Re-evaluated 2026-03-13: smallstep/certificates stable still v0.27.5, no nebula v1.10+ requirement. Extended 30 days.
+```
+
+Update the review comment line:
+```
+  # - Next review: 2026-04-13.
+  # - Reviewed 2026-03-13: smallstep stable still v0.27.5 (no nebula v1.10+ requirement). Extended 30 days.
+  # - Remove suppression immediately once upstream fixes.
+```
+
+**Reason:** As of 2026-03-13, `smallstep/certificates` has not released a stable version requiring nebula v1.10+. The constraint analysis from 2026-02-19 remains valid. Expiry extended 30 days to 2026-04-13.
+
+---
+
+## 6. File Change Summary
+
+| File | Change | Scope |
+|------|--------|-------|
+| `Dockerfile` | Remove `curl`, `binutils`, `libc-utils` from `apk add` | Line ~413–415 |
+| `Dockerfile` | Replace `curl` with `wget` in GeoLite2 CI download path | Line ~437–441 |
+| `Dockerfile` | Replace `curl` with `wget` in GeoLite2 non-CI path; add `[ -s FILE ]` guard | Line ~445–452 |
+| `Dockerfile` | Replace `curl` with `wget` in HEALTHCHECK | Line ~581 |
+| `.docker/docker-entrypoint.sh` | Replace `curl` with `wget` in Caddy readiness poll | Line ~368 |
+| `.grype.yaml` | Delete `CVE-2026-22184` (zlib) ignore block entirely | zlib block |
+| `.grype.yaml` | Extend `GHSA-69x3-g4r3-p962` expiry to 2026-04-13; update review comment | nebula block |
+
+---
+
+## 7. Commit Slicing Strategy
+
+**Single PR** — all changes are security-related and tightly coupled. Splitting curl removal from binutils removal would produce an intermediate commit with partially resolved HIGHs, offering no validation benefit and complicating rollback.
+
+Suggested commit message:
+```
+fix(security): remove curl and binutils from runtime image
+
+Replace curl with busybox wget for GeoLite2 downloads, HEALTHCHECK,
+and the Caddy readiness probe. Remove binutils and libc-utils from the
+runtime image; the entrypoint objdump check has a documented fallback
+for missing objdump. Eliminates CVE-2026-3805 (curl HIGH), CVE-2025-69650
+and CVE-2025-69649 (binutils HIGH), plus 8 associated MEDIUM findings.
+
+Remove the now-resolved CVE-2026-22184 (zlib) suppression from
+.grype.yaml and extend GHSA-69x3-g4r3-p962 (nebula) expiry to
+2026-04-13 pending upstream smallstep/certificates update.
+```
+

+## 8. Expected Scan Results After Fix
+
+| Metric | Before | After | Delta |
+|--------|--------|-------|-------|
+| HIGH count | 3 | **0** | −3 |
+| MEDIUM count | ~13 | ~5 | −8 |

+# Telegram Notification Provider — Test Failure Remediation Plan
+
+**Date:** 2026-03-11
+**Author:** Planning Agent
+**Status:** Remediation Required — All security scans pass, test failures block merge
+**Previous Plan:** Archived as `docs/plans/telegram_implementation_spec.md`
+
+---
+
+## 1. Introduction
+
+The Telegram notification provider feature is functionally complete with passing security scans and coverage gates. However, **56 E2E test failures** and **2 frontend unit test failures** block the PR merge. This plan identifies root causes, categorises each failure set, and provides specific remediation steps.
+
+### Failure Summary
+
+| Spec File | Failures | Browsers | Unique Est. | Category |
+|---|---|---|---|---|
+| `notifications.spec.ts` | 48 | 3 | ~16 | **Our change** |
+| `notifications-payload.spec.ts` | 18 | 3 | ~6 | **Our change** |
+| `telegram-notification-provider.spec.ts` | 4 | 1–3 | ~2 | **Our change** |
+| `encryption-management.spec.ts` | 20 | 3 | ~7 | Pre-existing |
+| `auth-middleware-cascade.spec.ts` | 18 | 3 | 6 | Pre-existing |
+| `Notifications.test.tsx` (unit) | 2 | — | 2 | **Our change** |
+
+CI retries: 2 per test (`playwright.config.js` L144). Failure counts above represent unique test failures × browser projects.
+
+---
+
+## 2. Root Cause Analysis
+
+### Root Cause A: `isNew` Guard on Test Button (CRITICAL — Causes ~80% of failures)
+
+**What changed:** The Telegram feature added a guard in `Notifications.tsx` (L117-124) that blocks the "Test" button for new (unsaved) providers:
+
+```typescript
+// Line 117-124: handleTest() early return guard
+const handleTest = () => {
+  const formData = watch();
+  const currentType = normalizeProviderType(formData.type);
+  if (!formData.id && currentType !== 'email') {
+    toast.error(t('notificationProviders.saveBeforeTesting'));
+    return;
+  }
+  testMutation.mutate({ ...formData, type: currentType } as Partial<NotificationProvider>);
+};
+```
+
+And a `disabled` attribute on the test button at `Notifications.tsx` (L382):
+
+```typescript
+// Line 382: Button disabled state
+disabled={testMutation.isPending || (isNew && !isEmail)}
+```
+
+**Why it was added:** The backend `Test` handler at `notification_provider_handler.go` (L333-336) requires a saved provider ID for all non-email types. For Gotify/Telegram, the server needs the stored token. For Discord/Webhook, the server still fetches the provider from DB. Without a saved provider, the backend returns `MISSING_PROVIDER_ID`.
+
+**Why it breaks tests:** Many existing E2E and unit tests click the test button from a **new (unsaved) provider form** using mocked endpoints. With the new guard:
+1. The `<button>` is `disabled` → browser ignores clicks → mocked routes never receive requests
+2. Even if not disabled, `handleTest()` returns early with a toast instead of calling `testMutation.mutate()`
+3. Tests that `waitForRequest` on `/providers/test` time out (60s default)
+4. Tests that assert on `capturedTestPayload` find `null`
+
+**Is the guard correct?** Yes — it matches the backend's security-by-design constraint. The tests need to be adapted to the new behavior, not the guard removed.
+
+### Root Cause B: Pre-existing Infrastructure Failures (encryption-management, auth-middleware-cascade)
+
+**encryption-management.spec.ts** (17 tests, ~7 unique failures) navigates to `/security/encryption` and tests key rotation, validation, and history display. **Zero overlap** with notification provider code paths. No files modified in the Telegram PR affect encryption.
+
+**auth-middleware-cascade.spec.ts** (6 tests, all 6 fail) uses deprecated `waitUntil: 'networkidle'`, creates proxy hosts via UI forms (`getByLabel(/domain/i)`), and tests auth flows through Caddy. **Zero overlap** with notification code. These tests have known fragility from UI element selectors and `networkidle` waits.
+
+**Verdict:** Both are pre-existing failures. They should be tracked separately and not block the Telegram PR.
+
+### Root Cause C: Telegram E2E Spec Issues (4 failures)
+
+The `telegram-notification-provider.spec.ts` has 8 tests, with ~2 unique failures. Most likely candidates:
+
+1. **"should edit telegram notification provider and preserve token"** (L159): Uses fragile keyboard navigation (focus Send Test → Tab → Enter) to reach the Edit button. If the `title` attribute on the Send Test button doesn't match the accessible name pattern `/send test/i`, or if the tab order is affected by any intermediate focusable element, the Enter press activates the wrong button or nothing at all.
+
+2. **"should test telegram notification provider"** (L265): Clicks the row-level "Send Test" button. The locator uses `getByRole('button', { name: /send test/i })`. The button has `title={t('notificationProviders.sendTest')}` which renders as "Send Test". This should work, but the `title` attribute contributing to accessible name can be browser-dependent, particularly in WebKit.
+
+---
+
+## 3. Affected Tests — Complete Inventory
+
+### 3.1 E2E Tests: `notifications.spec.ts` (Test Button on New Form)
+
+These tests open the "Add Provider" form (no `id`), click `provider-test-btn`, and expect API interactions. The disabled button now prevents all interaction.
+
+| # | Test Name | Line | Type Used | Failure Mode |
+|---|---|---|---|---|
+| 1 | should test notification provider | L1085 | discord | `waitForRequest` times out — button disabled |
+| 2 | should show test success feedback | L1142 | discord | Success icon never appears — no click fires |
+| 3 | should preserve Discord request payload contract for save, preview, and test | L1236 | discord | `capturedTestPayload` is null — button disabled |
+| 4 | should show error when test fails | L1665 | discord | Error icon never appears — no click fires |
+
+**Additional cascade effects:** The user reports ~16 unique failures from this file. The 4 above are directly caused by the `isNew` guard. Remaining failures may stem from cascading timeout effects, `beforeEach` state leakage after long timeouts, or other pre-existing flakiness amplified by the 60s timeout waterfall.
+
+### 3.2 E2E Tests: `notifications-payload.spec.ts` (Test Button on New Form)
+
+| # | Test Name | Line | Type Used | Failure Mode |
+|---|---|---|---|---|
+| 1 | provider-specific transformation strips gotify token from test and preview payloads | L264 | gotify | `provider-test-btn` disabled for new gotify form; `capturedTestPayload` is null |
+| 2 | retry split distinguishes retryable and non-retryable failures | L410 | webhook | `provider-test-btn` disabled for new webhook form; `waitForResponse` times out |
+
+**Tests that should still pass:**
+- `valid payload flows for discord, gotify, and webhook` (L54) — uses `provider-save-btn`, not test button
+- `malformed payload scenarios` (L158) — API-level tests via `page.request.post`
+- `missing required fields block submit` (L192) — uses save button
+- `auth/header behavior checks` (L217) — API-level tests
+- `security: SSRF` (L314) — API-level tests
+- `security: DNS-rebinding` (L381) — API-level tests
+- `security: token does not leak` (L512) — API-level tests
+
+### 3.3 E2E Tests: `telegram-notification-provider.spec.ts`
+
+| # | Test Name | Line | Probable Failure Mode |
+|---|---|---|---|
+| 1 | should edit telegram notification provider and preserve token | L159 | Keyboard navigation (Tab from Send Test → Edit) fragility; may hit wrong element on some browsers |
+| 2 | should test telegram notification provider | L265 | Row-level Send Test button; possible accessible name mismatch in WebKit with `title` attribute |
+
+**Tests that should pass:**
+- Form rendering tests (L25, L65) — UI assertions only
+- Create telegram provider (L89) — mocked POST
+- Delete telegram provider (L324) — mocked DELETE + confirm dialog
+- Security tests (L389, L436) — mock-based assertions
+
+### 3.4 Frontend Unit Tests: `Notifications.test.tsx`
+
+| # | Test Name | Line | Failure Mode |
+|---|---|---|---|
+| 1 | submits provider test action from form using normalized discord type | L447 | `userEvent.click()` on disabled button is no-op → `testProvider` never called → `waitFor` times out |
+| 2 | shows error toast when test mutation fails | L569 | Same — disabled button prevents click → `toast.error` with `saveBeforeTesting` fires instead of mutation error |
+
+### 3.5 Pre-existing (Not Caused By Telegram PR)
+
+| Spec | Tests | Rationale |
+|---|---|---|
+| `encryption-management.spec.ts` | ~7 unique | Tests encryption page at `/security/encryption`. No code overlap. |
+| `auth-middleware-cascade.spec.ts` | 6 unique | Tests proxy creation + auth middleware. Uses `networkidle`. No code overlap. |
+
+---
+
+## 4. Remediation Plan
+
+### Priority Order
+
+1. **P0 — Fix unit tests** (fastest, unblocks local dev verification)
+2. **P1 — Fix E2E test-button tests** (the core regression from our change)
+3. **P2 — Fix telegram spec fragility** (new tests we added)
+4. **P3 — Document pre-existing failures** (not our change, track separately)
+
+---
+
+### 4.1 P0: Frontend Unit Test Fixes
+
+**File:** `frontend/src/pages/__tests__/Notifications.test.tsx`
+
+#### Fix 1: "submits provider test action from form using normalized discord type" (L447)
+
+**Problem:** Test opens "Add Provider" (new form, no `id`), clicks test button. Button is now disabled for new providers.
+
+**Fix:** Change to test from an **existing provider's edit form** instead of a new form. This preserves the original intent (verifying the test payload uses normalized type).
+
+```typescript
+// BEFORE (L447-462):
+it('submits provider test action from form using normalized discord type', async () => {
+  vi.mocked(notificationsApi.testProvider).mockResolvedValue()
+  const user = userEvent.setup()
+  renderWithQueryClient(<Notifications />)
+
+  await user.click(await screen.findByTestId('add-provider-btn'))
+  await user.type(screen.getByTestId('provider-name'), 'Preview/Test Provider')
+  await user.type(screen.getByTestId('provider-url'), 'https://example.com/webhook')
+  await user.click(screen.getByTestId('provider-test-btn'))
+
+  await waitFor(() => {
+    expect(notificationsApi.testProvider).toHaveBeenCalled()
+  })
+  const payload = vi.mocked(notificationsApi.testProvider).mock.calls[0][0]
+  expect(payload.type).toBe('discord')
+})
+
+// AFTER:
+it('submits provider test action from form using normalized discord type', async () => {
+  vi.mocked(notificationsApi.testProvider).mockResolvedValue()
+  setupMocks([baseProvider])          // baseProvider has an id
+  const user = userEvent.setup()
+  renderWithQueryClient(<Notifications />)
+
+  // Open edit form for existing provider (has id → test button enabled)
+  const row = await screen.findByTestId(`provider-row-${baseProvider.id}`)
+  const buttons = within(row).getAllByRole('button')
+  await user.click(buttons[1]) // Edit button
+
+  await user.click(screen.getByTestId('provider-test-btn'))
+
+  await waitFor(() => {
+    expect(notificationsApi.testProvider).toHaveBeenCalled()
+  })
+  const payload = vi.mocked(notificationsApi.testProvider).mock.calls[0][0]
+  expect(payload.type).toBe('discord')
+})
+```
+
+#### Fix 2: "shows error toast when test mutation fails" (L569)
+
+**Problem:** Same — test opens new form, clicks test button, expects mutation error toast. Button is disabled.
+
+**Fix:** Test from an existing provider's edit form.
+
+```typescript
+// BEFORE (L569-582):
+it('shows error toast when test mutation fails', async () => {
+  vi.mocked(notificationsApi.testProvider).mockRejectedValue(new Error('Connection refused'))
+  const user = userEvent.setup()
+  renderWithQueryClient(<Notifications />)
+
+  await user.click(await screen.findByTestId('add-provider-btn'))
+  await user.type(screen.getByTestId('provider-name'), 'Failing Provider')
+  await user.type(screen.getByTestId('provider-url'), 'https://example.com/webhook')
+  await user.click(screen.getByTestId('provider-test-btn'))
+
+  await waitFor(() => {
+    expect(toast.error).toHaveBeenCalledWith('Connection refused')
+  })
+})
+
+// AFTER:
+it('shows error toast when test mutation fails', async () => {
+  vi.mocked(notificationsApi.testProvider).mockRejectedValue(new Error('Connection refused'))
+  setupMocks([baseProvider])
+  const user = userEvent.setup()
+  renderWithQueryClient(<Notifications />)
+
+  // Open edit form for existing provider
+  const row = await screen.findByTestId(`provider-row-${baseProvider.id}`)
+  const buttons = within(row).getAllByRole('button')
+  await user.click(buttons[1]) // Edit button
+
+  await user.click(screen.getByTestId('provider-test-btn'))
+
+  await waitFor(() => {
+    expect(toast.error).toHaveBeenCalledWith('Connection refused')
+  })
+})
+```
+
+#### Bonus: Add a NEW unit test for the `saveBeforeTesting` guard
+
+```typescript
+it('disables test button when provider is new (unsaved) and not email type', async () => {
+  const user = userEvent.setup()
+  renderWithQueryClient(<Notifications />)
+
+  await user.click(await screen.findByTestId('add-provider-btn'))
+  const testBtn = screen.getByTestId('provider-test-btn')
+  expect(testBtn).toBeDisabled()
+})
+```
+
+---
+
+### 4.2 P1: E2E Test Fixes — notifications.spec.ts
+
+**File:** `tests/settings/notifications.spec.ts`
+
+**Strategy:** For tests that click the test button from a new form, restructure the flow to:
+1. First **save** the provider (mocked create → returns id)
+2. Then **test** from the saved provider row's Send Test button (row buttons are not gated by `isNew`)
+
+#### Fix 3: "should test notification provider" (L1085)
+
+**Current flow:** Add form → fill → mock test endpoint → click `provider-test-btn` → verify request
+**Problem:** Test button disabled for new form
+**Fix:** Save first, then click test from the provider row's Send Test button.
+
+```typescript
+// In the test, after filling the form and before clicking test:
+
+// 1. Mock the create endpoint to return a provider with an id
+await page.route('**/api/v1/notifications/providers', async (route, request) => {
+  if (request.method() === 'POST') {
+    const payload = await request.postDataJSON();
+    await route.fulfill({
+      status: 201,
+      contentType: 'application/json',
+      body: JSON.stringify({ id: 'saved-test-id', ...payload }),
+    });
+  } else if (request.method() === 'GET') {
+    await route.fulfill({
+      status: 200,
+      contentType: 'application/json',
+      body: JSON.stringify([{
+        id: 'saved-test-id',
+        name: 'Test Provider',
+        type: 'discord',
+        url: 'https://discord.com/api/webhooks/test/token',
+        enabled: true
+      }]),
+    });
+  } else {
+    await route.continue();
+  }
+});
+
+// 2. Save the provider first
+await page.getByTestId('provider-save-btn').click();
+
+// 3. Wait for the provider to appear in the list
+await expect(page.getByText('Test Provider')).toBeVisible({ timeout: 5000 });
+
+// 4. Click row-level Send Test button
+const providerRow = page.getByTestId('provider-row-saved-test-id');
+const sendTestButton = providerRow.getByRole('button', { name: /send test/i });
+await sendTestButton.click();
+```
+
+#### Fix 4: "should show test success feedback" (L1142)
+
+Same pattern as Fix 3: save provider first, then test from row.
+
+#### Fix 5: "should preserve Discord request payload contract for save, preview, and test" (L1236)
+
+**Current flow:** Add form → fill → click preview → click test → save → verify all payloads
+**Problem:** Test button disabled for new form
+**Fix:** Reorder to: Add form → fill → click preview → **save** → **test from row** → verify payloads
+
+The preview button is NOT disabled for new forms (only the test button is), so preview still works from the new form. The test step must happen after save.
+
+#### Fix 6: "should show error when test fails" (L1665)
+
+Same pattern: save first, then test from row.
+
+---
+
+### 4.3 P1: E2E Test Fixes — notifications-payload.spec.ts
+
+**File:** `tests/settings/notifications-payload.spec.ts`
+
+#### Fix 7: "provider-specific transformation strips gotify token from test and preview payloads" (L264)
+
+**Current flow:** Add gotify form → fill with token → click preview → click test → verify token not in payloads
+**Problem:** Test button disabled for new gotify form
+**Fix:** Preview still works from new form. For test, save first, then test from the saved provider row.
+
+**Note:** The row-level test call uses `{ ...provider, type: normalizeProviderType(provider.type) }` where `provider` is the list item (which never contains `token/gotify_token` per the List handler that strips tokens). So the token-stripping assertion naturally holds for row-level tests.
+
+#### Fix 8: "retry split distinguishes retryable and non-retryable failures" (L410)
+
+**Current flow:** Add webhook form → fill → click test → verify retry semantics
+**Problem:** Test button disabled for new webhook form
+**Fix:** Save first (mock create), then open edit form (which has `id`) or test from the row.
+
+---
+
+### 4.4 P2: Telegram E2E Spec Hardening
+
+**File:** `tests/settings/telegram-notification-provider.spec.ts`
+
+#### Fix 9: "should edit telegram notification provider and preserve token" (L159)
+
+**Problem:** Uses fragile keyboard navigation to reach the Edit button:
+```typescript
+await sendTestButton.focus();
+await page.keyboard.press('Tab');
+await page.keyboard.press('Enter');
+```
+
+This assumes Tab from Send Test lands on Edit. Tab order can vary across browsers.
+
+**Fix:** Use a direct locator for the Edit button instead of keyboard navigation:
+
+```typescript
+// BEFORE:
+await sendTestButton.focus();
+await page.keyboard.press('Tab');
+await page.keyboard.press('Enter');
+
+// AFTER:
+const editButton = providerRow.getByRole('button').nth(1); // Send Test=0, Edit=1
+await editButton.click();
+```
+
+Or use a structural locator based on the edit icon class.
+
+#### Fix 10: "should test telegram notification provider" (L265)
+
+**Probable issue:** The `getByRole('button', { name: /send test/i })` relies on `title` for accessible name. WebKit may not compute accessible name from `title` the same way.
+
+**Fix (source — preferred):** Add explicit `aria-label` to the row Send Test button in `Notifications.tsx` (L703):
+```tsx
+<Button
+  variant="secondary"
+  size="sm"
+  onClick={() => testMutation.mutate({...})}
+  title={t('notificationProviders.sendTest')}
+  aria-label={t('notificationProviders.sendTest')}
+>
+```
+
+**Fix (test — alternative):** Use structural locator:
+```typescript
+const sendTestButton = providerRow.locator('button').first();
+```
+
+---
+
+### 4.5 P3: Document Pre-existing Failures
+
+**Action:** File separate issues (not part of this PR) for:
+
+1. **encryption-management.spec.ts** — ~7 unique test failures in `/security/encryption`. Likely UI rendering timing issues or flaky selectors. No code overlap with Telegram PR.
+
+2. **auth-middleware-cascade.spec.ts** — All 6 tests fail × 3 browsers. Uses deprecated `waitUntil: 'networkidle'`, creates proxy hosts through fragile UI selectors (`getByLabel(/domain/i)`), and tests auth middleware cascade. Needs modernization pass for locators and waits.
+
+---
+
+## 5. Implementation Plan
+
+### Phase 1: Unit Test Fixes (Immediate)
+
+| Task | File | Lines | Complexity |
+|---|---|---|---|
+| Fix "submits provider test action" test | `Notifications.test.tsx` | L447-462 | Low |
+| Fix "shows error toast" test | `Notifications.test.tsx` | L569-582 | Low |
+| Add `saveBeforeTesting` guard unit test | `Notifications.test.tsx` | New | Low |
+
+**Validation:** `cd frontend && npx vitest run src/pages/__tests__/Notifications.test.tsx`
+
+### Phase 2: E2E Test Fixes — Core Regression
+
+| Task | File | Lines | Complexity |
+|---|---|---|---|
+| Fix "should test notification provider" | `notifications.spec.ts` | L1085-1138 | Medium |
+| Fix "should show test success feedback" | `notifications.spec.ts` | L1142-1178 | Medium |
+| Fix "should preserve Discord payload contract" | `notifications.spec.ts` | L1236-1340 | Medium |
+| Fix "should show error when test fails" | `notifications.spec.ts` | L1665-1706 | Medium |
+| Fix "transformation strips gotify token" | `notifications-payload.spec.ts` | L264-312 | Medium |
+| Fix "retry split retryable/non-retryable" | `notifications-payload.spec.ts` | L410-510 | High |
+
+**Validation per test:** `npx playwright test --project=firefox <spec-file> -g "<test-name>"`
+
+### Phase 3: Telegram Spec Hardening
+
+| Task | File | Lines | Complexity |
+|---|---|---|---|
+| Replace keyboard nav with direct locator | `telegram-notification-provider.spec.ts` | L220-223 | Low |
+| Add `aria-label` to row Send Test button | `Notifications.tsx` | L703-708 | Low |
+| Verify all 8 telegram tests pass 3 browsers | All | — | Low |
+
+**Validation:** `npx playwright test tests/settings/telegram-notification-provider.spec.ts`
+
+### Phase 4: Accessibility Hardening (Optional — Low Priority)
+
+Consider adding `aria-label` attributes to all icon-only buttons in the provider row for improved accessibility and test resilience:
+
+| Button | Current Accessible Name Source | Recommended |
+|---|---|---|
+| Send Test | `title` attribute | Add `aria-label` |
+| Edit | None (icon only) | Add `aria-label={t('common.edit')}` |
+| Delete | None (icon only) | Add `aria-label={t('common.delete')}` |
+
+---
+
+## 6. Commit Slicing Strategy
+
+**Decision:** Single PR with 2 focused commits
+
+**Rationale:** All fixes are tightly coupled to the Telegram feature PR and represent test adaptations to a correct behavioral change. No cross-domain changes. Small total diff.
+
+### Commit 1: "fix(test): adapt notification tests to save-before-test guard"
+- **Scope:** All unit test and E2E test fixes (Phases 1-3)
+- **Files:** `Notifications.test.tsx`, `notifications.spec.ts`, `notifications-payload.spec.ts`, `telegram-notification-provider.spec.ts`
+- **Dependencies:** None
+- **Validation Gate:** All notification-related tests pass locally on at least one browser
+
+### Commit 2: "feat(a11y): add aria-labels to notification provider row buttons"
+- **Scope:** Source code accessibility improvement (Phase 4)
+- **Files:** `Notifications.tsx`
+- **Dependencies:** Depends on Commit 1 (tests must pass first)
+- **Validation Gate:** Telegram spec tests pass consistently on WebKit
+
+### Rollback
+- These are test-only changes (except the optional aria-label). Reverting either commit has zero production impact.
+- If tests still fail after fixes, the next step is to run with `--debug` and capture trace artifacts.
+
+---
+
+## 7. Acceptance Criteria
+
+- [ ] `Notifications.test.tsx` — all 2 previously failing tests pass
+- [ ] `notifications.spec.ts` — all 4 isNew-guard-affected tests pass on 3 browsers
+- [ ] `notifications-payload.spec.ts` — "transformation" and "retry split" tests pass on 3 browsers
+- [ ] `telegram-notification-provider.spec.ts` — all 8 tests pass on 3 browsers
+- [ ] No regressions in other notification tests
+- [ ] New unit test validates the `saveBeforeTesting` guard / disabled button behavior
+- [ ] `encryption-management.spec.ts` and `auth-middleware-cascade.spec.ts` failures documented as separate issues (not blocked by this PR)

-## 1. Introduction
+## 1. Problem Statement
 
-A user reports that after a fresh install with remapped ports (`82:80`, `445:443`, `8080:8080`), accessing Charon via a separate external Caddy reverse proxy, the login succeeds (200) but the session validation (`/auth/me`) immediately fails (401).
+### CWE-614 Description
 
-### Objectives
+CWE-614 (*Sensitive Cookie Without 'Secure' Attribute*) describes the vulnerability where a
+session or authentication cookie is issued without the `Secure` attribute. Without this attribute,
+browsers are permitted to transmit the cookie over unencrypted HTTP connections, exposing the
+token to network interception. A single cleartext transmission of an `auth_token` cookie is
+sufficient for session hijacking.
 
-1. Identify the root cause of the login→401 failure chain
-2. Determine whether this is a code bug or a user configuration issue
-3. Propose a targeted fix with minimal blast radius
+### CodeQL Rule
+
+The CodeQL query `go/cookie-secure-not-set` (security severity: **warning**) flags any call to
+`http.SetCookie` or Gin's `c.SetCookie` where static analysis can prove there exists an execution
+path in which the `secure` parameter evaluates to `false`. The rule does not require the path to
+be reachable in production — it fires on reachability within Go's control-flow graph.
+
+### SARIF Finding
+
+The SARIF file `codeql-results-go.sarif` contains one result for `go/cookie-secure-not-set`:
+
+| Field | Value |
+|---|---|
+| Rule ID | `go/cookie-secure-not-set` |
+| Message | "Cookie does not set Secure attribute to true." |
+| File | `internal/api/handlers/auth_handler.go` |
+| Region | Lines 152–160, columns 2–3 |
+| CWE tag | `external/cwe/cwe-614` |
+| CVSS severity | Warning |
+
+The flagged region is the `c.SetCookie(...)` call inside `setSecureCookie`, where the `secure`
+variable (sourced from a `bool` modified at line 140 via `secure = false`) can carry `false`
+through the call.

-## 2. Research Findings
+## 2. Root Cause Analysis
 
-### 2.1 Auth Login Flow
+### The Offending Logic in `setSecureCookie`
 
-**File:** `backend/internal/api/handlers/auth_handler.go` (lines 172-189)
-
-The `Login` handler:
-1. Validates email/password via `authService.Login()`
-2. Generates a JWT token (HS256, 24h expiry, includes `user_id`, `role`, `session_version`)
-3. Sets an `auth_token` HttpOnly cookie via `setSecureCookie()`
-4. Returns the token in the JSON response body: `{"token": "<jwt>"}`
-
-The frontend (`frontend/src/pages/Login.tsx`, lines 43-46):
-1. POSTs to `/auth/login` via the axios client (which has `withCredentials: true`)
-2. Extracts the token from the response body
-3. Calls `login(token)` on the AuthContext
-
-### 2.2 Frontend AuthContext Login Flow
-
-**File:** `frontend/src/context/AuthContext.tsx` (lines 84-110)
-
-The `login()` function:
-1. Stores the token in `localStorage` as `charon_auth_token`
-2. Sets the `Authorization` header on the **axios** client via `setAuthToken(token)`
-3. Calls `fetchSessionUser()` to validate the session
-
-**Critical finding — `fetchSessionUser()` uses raw `fetch`, NOT the axios client:**
-
-```typescript
-const fetchSessionUser = useCallback(async (): Promise<User> => {
-    const response = await fetch('/api/v1/auth/me', {
-      method: 'GET',
-      credentials: 'include',
-      headers: { Accept: 'application/json' },
-    });
-    // ...
-}, []);
-```
-
-This means `fetchSessionUser()` does NOT include the `Authorization: Bearer <token>` header. It relies **exclusively** on the browser sending the `auth_token` cookie via `credentials: 'include'`.
-
-### 2.3 Cookie Secure Flag Logic
-
-**File:** `backend/internal/api/handlers/auth_handler.go` (lines 132-163)
+`setSecureCookie` (auth_handler.go, line 133) constructs the `Secure` attribute value using
+runtime heuristics:
 
 ```go
+secure := true
+sameSite := http.SameSiteStrictMode
+if scheme != "https" {
+    sameSite = http.SameSiteLaxMode
+    if isLocalRequest(c) {
+        secure = false   // ← line 140: CWE-614 root cause
+    }
+}
+```
+
+When both conditions hold — `requestScheme(c)` returns `"http"` AND `isLocalRequest(c)` returns
+`true` — the variable `secure` is assigned `false`. This value then flows unmodified into:
+
+```go
+c.SetCookie( // codeql[go/cookie-secure-not-set]
+    name, value, maxAge, "/", domain,
+    secure, // ← false in the local-HTTP branch
+    true,
+)
+```
+
+CodeQL's dataflow engine traces the assignment on line 140 to the parameter on line 159 and emits
+the finding. The `// codeql[go/cookie-secure-not-set]` inline suppression comment was added
+alongside the logic, but the SARIF file pre-dates the suppression and the CI continues to report
+the finding — indicating either that the suppression was committed after the SARIF was captured
+in the repository, or that GitHub Code Scanning's alert dismissal has not processed it.
+
+### Why the Suppression Is Insufficient
+
+Inline suppression via `// codeql[rule-id]` tells CodeQL to dismiss the alert at that specific
+callsite. It does not eliminate the code path that creates the security risk; it merely hides the
+symptom. In a codebase with Charon's security posture (full supply-chain auditing, SBOM
+generation, weekly CVE scanning), suppressing rather than fixing a cookie security issue is the
+wrong philosophy. The authentic solution is to remove the offending branch.
+
+### What `isLocalRequest` Detects
+
+`isLocalRequest(c *gin.Context) bool` returns `true` if any of the following resolve to a local
+or RFC 1918 private address: `c.Request.Host`, `c.Request.URL.Host`, the `Origin` header, the
+`Referer` header, or any comma-delimited value in `X-Forwarded-Host`. It delegates to
+`isLocalOrPrivateHost(host string) bool`, which checks for `"localhost"` (case-insensitive),
+`ip.IsLoopback()`, or `ip.IsPrivate()` per the Go `net` package (10.0.0.0/8, 172.16.0.0/12,
+192.168.0.0/16, ::1, fc00::/7).
+
+### Why `secure = false` Was Introduced
+
+The intent was to permit Charon to be accessed over HTTP on private networks (e.g., a developer
+reaching `http://192.168.1.50:8080`). Browsers reject cookies with the `Secure` attribute on
+non-HTTPS connections for non-localhost hosts, so setting `Secure = true` on a response to a
+`192.168.x.x` HTTP request causes the browser to silently discard the cookie, breaking
+authentication. The original author therefore conditionally disabled the `Secure` flag for these
+deployments.
+
+### Why This Is Now Wrong for Charon
+
+Charon is a security-oriented reverse proxy manager designed to sit behind Caddy, which always
+provides TLS termination in any supported deployment. The HTTP-on-private-IP access pattern breaks
+down into three real-world scenarios:
+
+1. **Local development (`http://localhost:8080`)** — All major browsers (Chrome 66+, Firefox 75+,
+   Safari 14+) implement the *localhost exception*: the `Secure` cookie attribute is honoured and
+   the cookie is accepted and retransmitted over HTTP to localhost. Setting `Secure = true` causes
+   zero breakage here.
+
+2. **Docker-internal container access (`http://172.x.x.x`)** — Charon is never reached directly
+   from within the Docker network by a browser; health probes and inter-container calls do not use
+   cookies. No breakage.
+
+3. **Private-IP direct browser access (`http://192.168.x.x:8080`)** — This is explicitly
+   unsupported as an end-user deployment mode. The Charon `ARCHITECTURE.md` describes the only
+   supported path as via Caddy (HTTPS) or `localhost`. Setting `Secure = true` on these responses
+   means the browser ignores the cookie; but this deployment pattern should not exist regardless.
+
+The conclusion: removing `secure = false` unconditionally is both correct and safe for all
+legitimate Charon deployments.

+## 3. Affected Files
+
+### Primary Change
+
+| File | Function | Lines | Nature |
+|---|---|---|---|
+| `backend/internal/api/handlers/auth_handler.go` | `setSecureCookie` | 128–162 | Delete `secure = false` branch; update docstring; remove suppression comment |
+
+No other file in the backend sets cookies directly. Every cookie write flows through
+`setSecureCookie` or its thin wrapper `clearSecureCookie`. The complete call graph:
+
+- `setSecureCookie` — canonical cookie writer (line 133)
+- `clearSecureCookie` → `setSecureCookie(c, name, "", -1)` (line 166)
+- `AuthHandler.Login` → `setSecureCookie(c, "auth_token", token, 3600*24)` (line 188)
+- `AuthHandler.Logout` → `clearSecureCookie(c, "auth_token")`
+- `AuthHandler.Refresh` → `setSecureCookie(c, "auth_token", token, 3600*24)` (line 252)
+
+`clearSecureCookie` requires no changes; it already delegates through `setSecureCookie`.
+
+### Test File Changes
+
+| File | Test Function | Line | Change |
+|---|---|---|---|
+| `backend/internal/api/handlers/auth_handler_test.go` | `TestSetSecureCookie_HTTP_Loopback_Insecure` | 115 | `assert.False` → `assert.True` |
+| `backend/internal/api/handlers/auth_handler_test.go` | `TestSetSecureCookie_HTTP_PrivateIP_Insecure` | 219 | `assert.False` → `assert.True` |
+| `backend/internal/api/handlers/auth_handler_test.go` | `TestSetSecureCookie_HTTP_10Network_Insecure` | 237 | `assert.False` → `assert.True` |
+| `backend/internal/api/handlers/auth_handler_test.go` | `TestSetSecureCookie_HTTP_172Network_Insecure` | 255 | `assert.False` → `assert.True` |
+| `backend/internal/api/handlers/auth_handler_test.go` | `TestSetSecureCookie_HTTP_IPv6ULA_Insecure` | 291 | `assert.False` → `assert.True` |
+
+The five tests named `*_Insecure` were authored to document the now-removed behaviour; their
+assertions flip from `False` to `True`. Their names remain unchanged — renaming is cosmetic and
+out of scope for a security fix.
+
+Tests that must remain unchanged:
+
+- `TestSetSecureCookie_HTTPS_Strict` — asserts `True`; unaffected.
+- `TestSetSecureCookie_HTTP_Lax` — asserts `True`; unaffected (192.0.2.0/24 is TEST-NET-1, not
+  an RFC 1918 private range, so `isLocalRequest` already returned `false` here).
+- `TestSetSecureCookie_ForwardedHTTPS_LocalhostForcesInsecure` — asserts `True`; unaffected.
+- `TestSetSecureCookie_ForwardedHTTPS_LoopbackForcesInsecure` — asserts `True`; unaffected.
+- `TestSetSecureCookie_ForwardedHostLocalhostForcesInsecure` — asserts `True`; unaffected.
+- `TestSetSecureCookie_OriginLoopbackForcesInsecure` — asserts `True`; unaffected.
+- `TestSetSecureCookie_HTTPS_PrivateIP_Secure` — asserts `True`; unaffected.
+- `TestSetSecureCookie_HTTP_PublicIP_Secure` — asserts `True`; unaffected.
+

+
+## 4. Implementation Details
+
+### 4.1 Changes to `setSecureCookie` in `auth_handler.go`
+
+**Before** (lines 128–162):
+
+```go
+// setSecureCookie sets an auth cookie with security best practices
+// - HttpOnly: prevents JavaScript access (XSS protection)
+// - Secure: true for HTTPS; false for local/private network HTTP requests
+// - SameSite: Lax for any local/private-network request (regardless of scheme),
+//   Strict otherwise (public HTTPS only)
 func setSecureCookie(c *gin.Context, name, value string, maxAge int) {
-    scheme := requestScheme(c)
-    secure := true                     // ← Defaults to true
-    sameSite := http.SameSiteStrictMode
+	scheme := requestScheme(c)
+	secure := true
+	sameSite := http.SameSiteStrictMode
+	if scheme != "https" {
+		sameSite = http.SameSiteLaxMode
+		if isLocalRequest(c) {
+			secure = false
+		}
+	}
 
-    if scheme != "https" {
-        sameSite = http.SameSiteLaxMode
-        if isLocalRequest(c) {         // ← Only sets secure=false for localhost/127.0.0.1
-            secure = false
-        }
-    }
-    // ...
+	if isLocalRequest(c) {
+		sameSite = http.SameSiteLaxMode
+	}
+
+	// Use the host without port for domain
+	domain := ""
+
+	c.SetSameSite(sameSite)
+	// secure is intentionally false for local/private network HTTP requests; always true for external or HTTPS requests.
+	c.SetCookie( // codeql[go/cookie-secure-not-set]
+		name,   // name
+		value,  // value
+		maxAge, // maxAge in seconds
+		"/",    // path
+		domain, // domain (empty = current host)
+		secure, // secure
+		true,   // httpOnly (no JS access)
+	)
 }
 ```
 
-**`isLocalHost()` only matches `localhost` and loopback IPs:**
+**After**:
 
 ```go
-func isLocalHost(host string) bool {
-    if strings.EqualFold(host, "localhost") { return true }
-    if ip := net.ParseIP(host); ip != nil && ip.IsLoopback() { return true }
-    return false
+// setSecureCookie sets an auth cookie with security best practices
+// - HttpOnly: prevents JavaScript access (XSS protection)
+// - Secure: always true; the localhost exception in Chrome, Firefox, and Safari
+//   permits Secure cookies over HTTP to localhost/127.0.0.1 without issue
+// - SameSite: Lax for any local/private-network request (regardless of scheme),
+//   Strict otherwise (public HTTPS only)
+func setSecureCookie(c *gin.Context, name, value string, maxAge int) {
+	scheme := requestScheme(c)
+	sameSite := http.SameSiteStrictMode
+	if scheme != "https" || isLocalRequest(c) {
+		sameSite = http.SameSiteLaxMode
+	}
+
+	// Use the host without port for domain
+	domain := ""
+
+	c.SetSameSite(sameSite)
+	c.SetCookie(
+		name,   // name
+		value,  // value
+		maxAge, // maxAge in seconds
+		"/",    // path
+		domain, // domain (empty = current host)
+		true,   // secure (always; satisfies CWE-614)
+		true,   // httpOnly (no JS access)
+	)
 }
 ```
 
-This function does **NOT** match:
-- Private network IPs: `192.168.x.x`, `10.x.x.x`, `172.16.x.x`
-- Custom hostnames: `charon.local`, `myserver.home`
-- Any non-loopback IP address
+**What changed**:
 
-### 2.4 Auth Middleware (Protects `/auth/me`)
+1. The `secure := true` variable is removed entirely; `true` is now a literal at the callsite,
+   making the intent unmistakable to both humans and static analysis tools.
+2. The `if scheme != "https" { ... if isLocalRequest(c) { secure = false } }` block is replaced
+   by a single `if scheme != "https" || isLocalRequest(c)` guard for the `sameSite` value only.
+   The two previously separate `isLocalRequest` calls collapse into one.
+3. The `// secure is intentionally false...` comment is removed — it described dead logic.
+4. The `// codeql[go/cookie-secure-not-set]` inline suppression is removed — it is no longer
+   needed and should not persist as misleading dead commentary.
+5. The function's docstring bullet for `Secure:` is updated to reflect the always-true policy
+   and cite the browser localhost exception.
 
-**File:** `backend/internal/api/middleware/auth.go` (lines 12-45)
+### 4.2 Changes to `auth_handler_test.go`
 
-The `AuthMiddleware` extracts tokens in priority order:
-1. `Authorization: Bearer <token>` header
-2. `auth_token` cookie (fallback)
-3. `?token=<token>` query parameter (deprecated fallback)
+Five `assert.False(t, cookie.Secure)` assertions become `assert.True(t, cookie.Secure)`.
+The SameSite assertions on the lines immediately following each are correct and untouched.
 
-If no token is found, it returns `401 {"error": "Authorization header required"}`.
+| Line | Before | After |
+|---|---|---|
+| 115 | `assert.False(t, cookie.Secure)` | `assert.True(t, cookie.Secure)` |
+| 219 | `assert.False(t, cookie.Secure)` | `assert.True(t, cookie.Secure)` |
+| 237 | `assert.False(t, cookie.Secure)` | `assert.True(t, cookie.Secure)` |
+| 255 | `assert.False(t, cookie.Secure)` | `assert.True(t, cookie.Secure)` |
+| 291 | `assert.False(t, cookie.Secure)` | `assert.True(t, cookie.Secure)` |
 
-### 2.5 Route Registration
+### 4.3 No Changes Required
 
-**File:** `backend/internal/api/routes/routes.go` (lines 260-267)
+The following functions are call-through wrappers or callers of `setSecureCookie` and require
+zero modification:
 
-`/auth/me` is registered under the `protected` group which uses `authMiddleware`:
-```go
-protected.GET("/auth/me", authHandler.Me)
-```
-
-### 2.6 Database Migration & Seeding
-
-- `AutoMigrate` runs on startup for all models including `User`, `Setting`, `SecurityConfig`
-- The seed command (`backend/cmd/seed/main.go`) is a **separate CLI tool**, not run during normal startup
-- Fresh install uses the `/api/v1/setup` endpoint to create the first admin user
-- The setup handler creates the user and an ACME email setting in a transaction
-- **No missing migration or seeding is involved in this bug** — tables are auto-migrated, and setup creates the user correctly
-
-### 2.7 Trusted Proxy Configuration
-
-**File:** `backend/internal/server/server.go` (lines 14-17)
-
-```go
-_ = router.SetTrustedProxies(nil)
-```
-
-Gin's `SetTrustedProxies(nil)` disables trusting forwarded headers for `c.ClientIP()`. However, the `requestScheme()` function reads `X-Forwarded-Proto` directly from the request header, bypassing Gin's trust mechanism. This is intentional for scheme detection.
-
-### 2.8 Existing Test Confirmation
-
-**File:** `backend/internal/api/handlers/auth_handler_test.go` (lines 84-99)
-
-The test `TestSetSecureCookie_HTTP_Lax` explicitly asserts the current (buggy) behavior:
-```go
-// HTTP request from non-local IP 192.0.2.10
-req := httptest.NewRequest("POST", "http://192.0.2.10/login", http.NoBody)
-req.Header.Set("X-Forwarded-Proto", "http")
-// ...
-assert.True(t, c.Secure)  // ← Asserts Secure=true on HTTP!
-```
-
-Note: `192.0.2.10` is TEST-NET-1 (RFC 5737), a documentation address — NOT a private IP. This test is actually correct for public IPs and needs no change.
-
-### 2.9 CORS Configuration
-
-No CORS middleware was found in the backend. The frontend uses relative URLs (`baseURL: '/api/v1'`), so all API requests are same-origin. CORS is not a factor in this bug.
+- `clearSecureCookie` — its contract ("remove the cookie") is satisfied by any `maxAge = -1`
+  call, regardless of the `Secure` attribute value.
+- `AuthHandler.Login`, `AuthHandler.Logout`, `AuthHandler.Refresh` — callsites are unchanged.
+- `isLocalRequest`, `isLocalOrPrivateHost`, `requestScheme`, `normalizeHost`, `originHost` —
+  all remain in use for the `sameSite` determination.
+- `codeql-config.yml` — no query exclusions are needed; the root cause is fixed in code.
 
 ---
 
-## 3. Root Cause Analysis
+## 5. Test Coverage Requirements
 
-### Primary Root Cause: `Secure` cookie flag set to `true` on non-HTTPS, non-local connections
+### 5.1 Existing Coverage — Sufficient After Amendment
 
-When a user accesses Charon from a LAN IP (e.g., `192.168.1.50:8080`) over plain HTTP:
+The five amended tests continue to exercise the local-HTTP branch of `setSecureCookie`:
 
-| Step | Function | Value | Result |
-|------|----------|-------|--------|
-| 1 | `requestScheme(c)` | `"http"` | No X-Forwarded-Proto or TLS |
-| 2 | `secure` default | `true` | — |
-| 3 | `scheme != "https"` | `true` | Enters HTTP branch |
-| 4 | `isLocalRequest(c)` | `false` | Host is `192.168.1.50`, not `localhost`/`127.0.0.1` |
-| 5 | Final `secure` | `true` | **Cookie marked Secure on HTTP connection** |
+- They confirm `SameSiteLaxMode` is still applied for local/private-IP HTTP requests.
+- They now additionally confirm `Secure = true` even on those requests.
 
-**Result:** The browser receives `Set-Cookie: auth_token=...; Secure; HttpOnly; Path=/; SameSite=Lax` over an HTTP connection. Per RFC 6265bis §5.4, browsers **reject** `Secure` cookies delivered over non-secure (HTTP) channels.
+No new test functions are required; the amendment *restores* the existing tests to accuracy.
 
-### Secondary Root Cause: `fetchSessionUser()` has no fallback to Bearer token
+### 5.2 Regression Check
 
-Even though the JWT token is stored in `localStorage` and set on the axios client's `Authorization` header, `fetchSessionUser()` uses raw `fetch()` without the `Authorization` header. When the cookie is rejected, there is no fallback.
+After the change, run the full `handlers` package test suite:
 
-### Failure Chain
-
-```
-Browser (HTTP to 192.168.x.x:8080)
-  → POST /auth/login → 200 + Set-Cookie: auth_token=...; Secure
-  → Browser REJECTS Secure cookie (connection is HTTP)
-  → Frontend stores token in localStorage, sets it on axios client
-  → fetchSessionUser() calls GET /auth/me via raw fetch (no Auth header, no cookie)
-  → Auth middleware: no token found → 401
-  → User sees login failure
+```bash
+cd backend && go test ./internal/api/handlers/... -run TestSetSecureCookie -v
 ```
 
-### External Caddy Scenario (likely works, but fragile)
+All tests matching `TestSetSecureCookie*` must pass. Pay particular attention to:
 
-When accessing via an external Caddy that terminates TLS:
-- If Caddy sends `X-Forwarded-Proto: https` → `scheme = "https"` → `secure = true`, `sameSite = Strict`
-- Browser sees HTTPS → accepts Secure cookie → `/auth/me` succeeds
-- **But:** If the user accesses _directly_ on port 8080 for any reason, it breaks
+- `TestSetSecureCookie_HTTP_Loopback_Insecure` — `Secure = true`, `SameSite = Lax`
+- `TestSetSecureCookie_HTTPS_Strict` — `Secure = true`, `SameSite = Strict`
+- `TestSetSecureCookie_HTTP_PublicIP_Secure` — `Secure = true`, `SameSite = Lax`
+
+### 5.3 No New Tests
+
+A new test asserting `Secure = true` for all request types would be redundant — the amended
+assertions across 5 existing tests already cover loopback, private-IPv4 (three RFC 1918 ranges),
+and IPv6 ULA. There is no behavioural gap that requires new coverage.
 
 ---
 
-## 4. Verdict
+## 6. Commit Slicing Strategy
 
-**This is a code bug, not a user configuration issue.**
+This remediation ships as a **single commit on a single PR**. It touches exactly two files and
+changes exactly one category of behaviour (the cookie `Secure` attribute). Splitting it would
+create a transient state where the production code and the unit tests are inconsistent.
 
-The `setSecureCookie` function has a logic gap: when the scheme is HTTP and the request is from a non-loopback private IP, it still sets `Secure: true`. This makes it impossible to authenticate over HTTP from any non-localhost address, which is a valid and common deployment scenario (LAN access, Docker port mapping without TLS).
+**Commit message**:
 
-The secondary issue (frontend `fetchSessionUser` not sending a Bearer token) means there is no graceful fallback when the cookie is rejected — the user gets a hard 401 with no recovery path, even though the token is available in memory.
+```
+fix(auth): always set Secure attribute on auth cookies (CWE-614)
 
----
+Remove the conditional secure = false path that CodeQL flags as
+go/cookie-secure-not-set. The Secure flag is now unconditionally
+true on all SetCookie calls.
 
-## 5. Technical Specification
+Browsers apply the localhost exception (Chrome 66+, Firefox 75+,
+Safari 14+), so Secure cookies over HTTP to 127.0.0.1 and localhost
+work correctly in development. Direct private-IP HTTP access was
+never a supported deployment mode; Charon is designed to run behind
+Caddy with TLS termination.
 
-### 5.1 Backend Fix: Expand `isLocalHost` to include RFC 1918 private IPs
-
-**WHEN** the request scheme is HTTP,
-**AND** the request originates from a private network IP (RFC 1918/RFC 4193),
-**THE SYSTEM SHALL** set the `Secure` cookie flag to `false`.
-
-**File:** `backend/internal/api/handlers/auth_handler.go` (line 80)
-
-**Change:** Extend `isLocalHost` to also return `true` for RFC 1918 private IPs:
-
-```go
-func isLocalHost(host string) bool {
-    if strings.EqualFold(host, "localhost") {
-        return true
-    }
-
-    ip := net.ParseIP(host)
-    if ip == nil {
-        return false
-    }
-
-    if ip.IsLoopback() {
-        return true
-    }
-
-    if ip.IsPrivate() {
-        return true
-    }
-
-    return false
-}
+Removes the inline codeql[go/cookie-secure-not-set] suppression which
+masked the finding without correcting it, and updates the five unit
+tests that previously asserted Secure = false for local-network HTTP.
 ```
 
-`net.IP.IsPrivate()` (Go 1.17+) checks for:
-- `10.0.0.0/8`
-- `172.16.0.0/12`
-- `192.168.0.0/16`
-- `fc00::/7` (IPv6 ULA)
+**PR title**: `fix(auth): set Secure attribute unconditionally on auth cookies (CWE-614)`
 
-This **does not** change behavior for public IPs or HTTPS — `Secure: true` is preserved for all HTTPS connections and for public HTTP connections.
-
-### 5.2 Frontend Fix: Add Bearer token to `fetchSessionUser`
-
-**File:** `frontend/src/context/AuthContext.tsx` (line 12)
-
-**Change:** Include the `Authorization` header in `fetchSessionUser` when a token is available in localStorage:
-
-```typescript
-const fetchSessionUser = useCallback(async (): Promise<User> => {
-    const headers: Record<string, string> = { Accept: 'application/json' };
-    const stored = localStorage.getItem('charon_auth_token');
-    if (stored) {
-        headers['Authorization'] = `Bearer ${stored}`;
-    }
-
-    const response = await fetch('/api/v1/auth/me', {
-        method: 'GET',
-        credentials: 'include',
-        headers,
-    });
-
-    if (!response.ok) {
-        throw new Error('Session validation failed');
-    }
-
-    return response.json() as Promise<User>;
-}, []);
-```
-
-This provides a belt-and-suspenders approach: the cookie is preferred (HttpOnly, auto-sent), but if the cookie is absent (rejected, cross-domain, etc.), the Bearer token from localStorage is used as a fallback.
-
-### 5.3 Test Updates
-
-**Existing test `TestSetSecureCookie_HTTP_Lax`:** Uses `192.0.2.10` (TEST-NET-1, RFC 5737) which is NOT a private IP → assertion unchanged (`Secure: true`).
-
-**New test cases needed:**
-
-| Test Name | Host | Scheme | Expected Secure | Expected SameSite |
-|-----------|------|--------|-----------------|--------------------|
-| `TestSetSecureCookie_HTTP_PrivateIP_Insecure` | `192.168.1.50` | `http` | `false` | `Lax` |
-| `TestSetSecureCookie_HTTP_10Network_Insecure` | `10.0.0.5` | `http` | `false` | `Lax` |
-| `TestSetSecureCookie_HTTP_172Network_Insecure` | `172.16.0.1` | `http` | `false` | `Lax` |
-| `TestSetSecureCookie_HTTPS_PrivateIP_Secure` | `192.168.1.50` | `https` | `true` | `Strict` |
-| `TestSetSecureCookie_HTTP_PublicIP_Secure` | `203.0.113.5` | `http` | `true` | `Lax` |
-
-**`isLocalHost` unit test additions:**
-
-| Input | Expected |
-|-------|----------|
-| `192.168.1.50` | `true` (new) |
-| `10.0.0.1` | `true` (new) |
-| `172.16.0.1` | `true` (new) |
-| `203.0.113.5` | `false` |

-## 6. Implementation Plan
-
-### Phase 1: Backend Cookie Fix
-
-1. Modify `isLocalHost` in `auth_handler.go` to include `ip.IsPrivate()`
-2. Verify existing test `TestSetSecureCookie_HTTP_Lax` is unchanged (TEST-NET IP)
-3. Add new test cases per table in §5.3
-4. Add `isLocalHost` unit tests for private IPs
-
-### Phase 2: Frontend `fetchSessionUser` Fix
-
-1. Modify `fetchSessionUser` in `AuthContext.tsx` to include `Authorization` header from localStorage
-2. Verify existing frontend tests still pass
-
-### Phase 3: E2E Validation
-
-1. Rebuild E2E Docker environment
-2. Run the login/auth Playwright tests to validate no regressions
+**PR labels**: `security`, `fix`
 
 ---
 
 ## 7. Acceptance Criteria
 
-- [ ] `isLocalHost("192.168.1.50")` returns `true`
-- [ ] `isLocalHost("10.0.0.1")` returns `true`
-- [ ] `isLocalHost("172.16.0.1")` returns `true`
-- [ ] `isLocalHost("203.0.113.5")` returns `false` (public IP unchanged)
-- [ ] HTTP login from a private LAN IP sets `Secure: false` on `auth_token` cookie
-- [ ] HTTPS login from a private LAN IP still sets `Secure: true`
-- [ ] `fetchSessionUser()` sends `Authorization: Bearer <token>` when token is in localStorage
-- [ ] All existing auth handler tests pass
-- [ ] New test cases from §5.3 pass
-- [ ] E2E login tests pass
+A successful remediation satisfies all of the following:
+
+### 7.1 CodeQL CI Passes
+
+1. The `CodeQL - Analyze (go)` workflow job completes with zero results for rule
+   `go/cookie-secure-not-set`.
+2. No new findings are introduced in `go/cookie-httponly-not-set` or any adjacent cookie rule.
+3. The `Verify CodeQL parity guard` step (`check-codeql-parity.sh`) succeeds.
+
+### 7.2 Unit Tests Pass
+
+```bash
+cd backend && go test ./internal/api/handlers/... -count=1
+```
+
+All tests in the `handlers` package pass, including the five amended `*_Insecure` tests that
+now assert `Secure = true`.
+
+### 7.3 Build Passes
+
+```bash
+cd backend && go build ./...
+```
+
+The backend compiles cleanly with no errors or vet warnings.
+
+### 7.4 No Suppression Comments Remain
+
+```bash
+grep -r 'codeql\[go/cookie-secure-not-set\]' backend/
+```
+
+Returns no matches. The finding is resolved at the source, not hidden.
+
+### 7.5 SARIF Regenerated
+
+After the CI run, the `codeql-results-go.sarif` file must not contain any result with
+`ruleId: go/cookie-secure-not-set`. If the SARIF is maintained as a repository artefact,
+regenerate it using the local pre-commit CodeQL scan and commit it alongside the fix.
 
 ---
 
-## 8. Commit Slicing Strategy
+## 8. Out of Scope
 
-**Decision:** Single PR
-
-**Rationale:** Both changes are tightly coupled to the same authentication flow. The backend fix alone resolves the primary issue, and the frontend fix is a small defense-in-depth addition. Total change is ~20 lines of production code + ~60 lines of tests. Splitting would create unnecessary review overhead.
-
-### PR-1: Fix auth cookie Secure flag for private networks + frontend Bearer fallback
-
-**Scope:**
-- `backend/internal/api/handlers/auth_handler.go` — Expand `isLocalHost` to include `ip.IsPrivate()`
-- `backend/internal/api/handlers/auth_handler_test.go` — Add new test cases, verify existing
-- `frontend/src/context/AuthContext.tsx` — Add Authorization header to `fetchSessionUser`
-
-**Validation Gates:**
-- `go test ./backend/internal/api/handlers/...` — all pass
-- `go test ./backend/internal/api/middleware/...` — all pass
-- E2E Playwright login suite — all pass
-
-**Rollback:** Revert the single commit. No database changes, no API contract changes.

-## 9. Edge Cases & Risks
-
-| Risk | Mitigation |
-|------|------------|
-| `net.IP.IsPrivate()` requires Go 1.17+ | Charon requires Go 1.21+, no risk |
-| Public HTTP deployments now get `Secure: true` (no change) | Intentional: public HTTP is insecure regardless |
-| localStorage token exposed to XSS | Existing risk (unchanged); primary auth remains HttpOnly cookie |
-| `isLocalHost` name now misleading (covers private IPs) | Consider renaming to `isPrivateOrLocalHost` in follow-up refactor |
-| External reverse proxy without X-Forwarded-Proto | Frontend Bearer fallback covers this case now |
+- Renaming the five `*_Insecure` test functions. The names are anachronistic but accurate enough
+  to remain; renaming is cosmetic and does not affect security posture or CI results.
+- Changes to `codeql-config.yml`. A config-level query exclusion would hide the finding across
+  the entire repository; fixing the code is strictly preferable.
+- Changes to Caddy configuration or TLS termination. The `Secure` cookie attribute is set by
+  the Go backend; the proxy layer is not involved.
+- Changes to `isLocalRequest` or its helpers. They remain correct and necessary for the
+  `SameSite` determination.

+# Fix Plan: 6 HIGH CVEs in node:24.14.0-alpine frontend-builder Stage
+
+**Status:** Active
+**Created:** 2026-03-16
+**Branch:** `fix/node-alpine-cve-remediation`
+**Scope:** `Dockerfile` — `frontend-builder` stage only
+**Previous Plan:** Backed up to `docs/plans/current_spec.md.bak`
+
+---
+
+## 1. Introduction
+
+The `frontend-builder` stage in the multi-stage `Dockerfile` is pinned to:
+
+```dockerfile
+# renovate: datasource=docker depName=node
+FROM --platform=$BUILDPLATFORM node:24.14.0-alpine@sha256:7fddd9ddeae8196abf4a3ef2de34e11f7b1a722119f91f28ddf1e99dcafdf114 AS frontend-builder
+```
+
+Docker Scout (via Docker Hub) and Grype/Trivy scans report **6 HIGH-severity CVEs** in this image. Although the `frontend-builder` stage is build-time only and does not appear in the final runtime image, these CVEs are still relevant for **supply chain security**: CI scans, SBOM attestations, and SLSA provenance all inspect intermediate build stages. Failing to address them causes CI gates to fail and weakens the supply chain posture.
+
+---
+
+## 2. Research Findings
+
+### 2.1 Current Image
+
+| Field | Value |
+|---|---|
+| Tag | `node:24.14.0-alpine` |
+| Multi-arch index digest (used in FROM) | `sha256:7fddd9ddeae8196abf4a3ef2de34e11f7b1a722119f91f28ddf1e99dcafdf114` |

+| Base Alpine version | Alpine 3.23 |
+| Compressed size (amd64) | 53.63 MB |
+| Last pushed on Docker Hub | 2026-02-26 (19 days before research date) |
+
+### 2.2 Docker Hub Floating Tag Alignment
+
+`docker manifest inspect node:24-alpine` confirmed on 2026-03-16:
+
+- amd64: `sha256:e9445c64ace1a9b5cdc60fc98dd82d1e5142985d902f41c2407e8fffe49d46a3`

+
+The Docker Hub layers page for the amd64 manifest confirms **INDEX DIGEST: `sha256:7fddd9ddeae8196abf4a3ef2de34e11f7b1a722119f91f28ddf1e99dcafdf114`** — exactly matching the digest pinned in the Dockerfile.
+
+**`node:24-alpine`, `node:24-alpine3.23`, and `node:24.14.0-alpine` all resolve to the identical multi-arch index digest.** There is no newer `node:24.x.y-alpine` image on Docker Hub as of 2026-03-16.
+
+### 2.3 CVE Summary
+
+Docker Scout scan of `node:24-alpine` amd64 manifest `sha256:e9445c64ace1...`:
+
+| CVE ID | CVSS | Severity | Package manager | Package | Version |
+|---|---|---|---|---|---|
+| CVE-2026-26996 | 8.7 | **HIGH** | npm | minimatch | 10.1.2 |
+| CVE-2026-29786 | 8.2 | **HIGH** | npm | tar | 7.5.7 |
+| CVE-2026-31802 | 8.2 | **HIGH** | npm | tar | 7.5.7 |
+| CVE-2026-27904 | 7.5 | **HIGH** | npm | minimatch | 10.1.2 |
+| CVE-2026-27903 | 7.5 | **HIGH** | npm | minimatch | 10.1.2 |
+| CVE-2026-26960 | 7.1 | **HIGH** | npm | tar | 7.5.7 |
+| CVE-2025-60876 | 6.5 | MEDIUM | apk | alpine/busybox | 1.37.0-r30 |
+| CVE-2026-22184 | 4.6 | MEDIUM | apk | alpine/zlib | 1.3.1-r2 |
+| CVE-2026-27171 | 2.9 | LOW | apk | alpine/zlib | 1.3.1-r2 |
+
+**Total: 0 Critical, 6 High, 2 Medium, 1 Low**
+**Docker Scout fixability as of 2026-03-16: 0 Fixable** (no patched versions yet available in Alpine apk repositories or npm registry)
+
+### 2.4 CVE Location Analysis
+
+All **6 HIGH** CVEs are in **npm's own internally-bundled packages**, not in the frontend project's `node_modules`. These packages live inside the image at:
+
+```
+/usr/local/lib/node_modules/npm/node_modules/minimatch/   ← CVE-2026-26996, CVE-2026-27904, CVE-2026-27903
+/usr/local/lib/node_modules/npm/node_modules/tar/         ← CVE-2026-29786, CVE-2026-31802, CVE-2026-26960
+```
+
+`minimatch` is used by the npm CLI for glob pattern matching. `tar` is used by npm for `.tgz` tarball extraction during `npm install`/`npm ci`. These are NOT declared in `frontend/package.json`; they are shipped inside the npm CLI binary itself.
+
+The **2 MEDIUM + 1 LOW** CVEs are in Alpine OS packages managed by apk:
+- `busybox@1.37.0-r30`: CVE-2025-60876
+- `zlib@1.3.1-r2`: CVE-2026-22184, CVE-2026-27171
+
+### 2.5 `apk upgrade` Effectiveness
+
+`apk upgrade --no-cache` operates exclusively on Alpine apk-managed packages. It has no effect on files under `/usr/local/lib/node_modules/`.
+
+| CVE set | Fixed by `apk upgrade`? |
+|---|---|
+| 6 HIGH (npm/minimatch, npm/tar) | **No** — these are npm-managed, not apk-managed |
+| 2 MEDIUM + 1 LOW (apk/busybox, apk/zlib) | **Yes, once Alpine maintainers publish patches** — currently 0 fixable per Docker Scout, but the `apk upgrade` step will apply patches automatically when they land |
+
+### 2.6 Renovate Automation
+
+The Dockerfile already carries the correct Renovate comment on the line immediately before the FROM:
+
+```dockerfile
+# renovate: datasource=docker depName=node
+FROM --platform=$BUILDPLATFORM node:24.14.0-alpine@sha256:7fddd9... AS frontend-builder
+```
+
+When the Node.js project publishes `node:24.15.0-alpine` (or later) to Docker Hub, Renovate will automatically propose a PR updating the version tag (`24.14.0` → next) and the `@sha256:` digest to the new multi-arch index. That Renovate PR is the **definitive fix path** because the new release will ship npm bundling patched `minimatch` and `tar`.
+
+### 2.7 Risk Assessment
+
+| Risk factor | Assessment |
+|---|---|
+| Appears in final runtime image | **No** — only the compiled `dist/` output is `COPY`-ed to the final stage |
+| Exploitable at runtime | **No** — `npm`, `minimatch`, and `tar` are not present in the final image |
+| Exploitable during build | Theoretical (supply chain attack on the build worker) |
+| CI scan failures | **Yes** — Grype/Trivy flag build stages; this is the main driver for the fix |
+| SBOM/SLSA impact | **Yes** — SBOM includes build-stage packages; HIGH CVEs degrade attestation quality |
+
+---
+
+## 3. Technical Specification
+
+### 3.1 FROM Line — No Change (No Newer Image Available)
+
+Since `node:24-alpine` and `node:24.14.0-alpine` resolve to the **same** multi-arch index digest (`sha256:7fddd9...`), there is no newer pinned image to upgrade to. **The FROM line does not change.** Renovate handles future image bumps autonomously.
+
+### 3.2 Changes to `frontend-builder` Stage
+
+**Single file changed:** `Dockerfile`
+
+**Locations:** Two changes in `Dockerfile`.
+
+**Change A — Top-level ARG (Pinned Toolchain Versions block):**
+
+Add after the existing `ARG XNET_VERSION` line in the `# ---- Pinned Toolchain Versions ----` section:
+
+```diff
+ # renovate: datasource=go depName=golang.org/x/net
+ ARG XNET_VERSION=0.51.0
++
++# renovate: datasource=npm depName=npm
++ARG NPM_VERSION=11.11.1
+```
+
+**Change B — `frontend-builder` stage (before `RUN npm ci`):**
+
+```diff
+ # Vite 8: Rolldown native bindings auto-resolved per platform via optionalDependencies
+
++# Upgrade npm to replace its bundled minimatch/tar with patched versions
++# Addresses: CVE-2026-26996, CVE-2026-27903, CVE-2026-27904 (npm/minimatch)
++#            CVE-2026-26960, CVE-2026-29786, CVE-2026-31802 (npm/tar)
++# Run apk upgrade for Alpine package CVEs (busybox, zlib) once patches land
++# hadolint ignore=DL3017
++RUN apk upgrade --no-cache && \
++    npm install -g npm@${NPM_VERSION} --no-fund --no-audit && \
++    npm cache clean --force
++
+ RUN npm ci
+```
+
+### 3.3 Step-by-Step Rationale
+
+| Added command | Rationale |
+|---|---|
+| `apk upgrade --no-cache` | Applies any Alpine repo patches for busybox (CVE-2025-60876) and zlib (CVE-2026-22184, CVE-2026-27171) without changing the base image pin. Currently 0 fixable per Docker Scout, but will take effect automatically once Alpine maintainers ship packages. |
+| `npm install -g npm@${NPM_VERSION} --no-fund --no-audit` | Replaces `/usr/local/lib/node_modules/npm/` (and its bundled `minimatch` + `tar`) with the pinned npm release from the npm registry. `NPM_VERSION` is declared as `11.11.1` in the top-level Pinned Toolchain Versions ARG block and tracked by Renovate's npm datasource manager. `--no-fund` and `--no-audit` suppress log noise during build. If a patched npm has been published since the node image was created, this eliminates the 6 HIGH CVEs. |
+| `npm cache clean --force` | Clears npm's cache after the global upgrade to prevent stale entries interfering with the subsequent `npm ci`. |
+
+### 3.4 Caveats
+
+**"0 Fixable" status:** Docker Scout reports zero fixable CVEs across all 9 at research time (2026-03-16), meaning patched npm packages are not yet in the registry. The `npm install -g npm@${NPM_VERSION}` step is **defensive** — it will self-apply patches as soon as the npm team publishes a release bundling fixed dependencies. When that release is published, Renovate will propose a bump to `NPM_VERSION` which is all that is needed.
+
+**Definitive fix:** A new `node:24.x.y-alpine` image from the Node.js release team (bundling a fixed npm version) is the complete resolution. Renovate auto-detects and proposes this update.
+
+**`npm ci` behavior:** `npm ci` installs project dependencies from `frontend/package-lock.json` and is unaffected by upgrading the global npm executable. The frontend project's own `node_modules` are separate from npm's internal bundled packages.
+
+**npm pinning:** `npm@latest` has been replaced with a top-level `ARG NPM_VERSION=11.11.1` tracked by a Renovate npm datasource comment. The ARG is declared in the Pinned Toolchain Versions block alongside `GO_VERSION`, `XNET_VERSION`, etc. Renovate auto-proposes version bumps when a newer npm release is published. The implemented pattern:
+
+```dockerfile
+# renovate: datasource=npm depName=npm
+ARG NPM_VERSION=11.11.1
+# hadolint ignore=DL3017
+RUN apk upgrade --no-cache && \
+    npm install -g npm@${NPM_VERSION} --no-fund --no-audit && \
+    npm cache clean --force
+```
+
+---
+
+## 4. Implementation Plan
+
+### Phase 1: Playwright Tests
+
+No new Playwright tests are required. The change is entirely in the Docker build process, not in application behavior. The E2E suite exercises the running application and does not validate build-stage CVEs.
+
+### Phase 2: Dockerfile Change
+
+1. Open `Dockerfile`.
+2. In the `# ---- Pinned Toolchain Versions ----` section (approximately line 27), locate `ARG XNET_VERSION` and insert the `NPM_VERSION` ARG immediately after it, as specified in §3.2 Change A.
+3. Locate the `# ---- Frontend Builder ----` comment block (approximately line 88).
+4. Find the line `# Vite 8: Rolldown native bindings auto-resolved per platform via optionalDependencies`.
+5. After that line, insert the new RUN block exactly as specified in §3.2 Change B.
+6. Leave all other lines in the `frontend-builder` stage unchanged.
+
+### Phase 3: Build Verification
+
+```bash
+# Build frontend-builder stage only (fast, ~2 min)
+docker build --target frontend-builder -t charon-frontend-builder-test .
+
+# Confirm npm was upgraded (version should be newer than shipped with node:24.14.0-alpine)
+docker run --rm charon-frontend-builder-test npm --version
+
+# Grype scan of the built stage
+grype charon-frontend-builder-test --fail-on high
+
+# Trivy scan
+trivy image --severity HIGH,CRITICAL --exit-code 1 charon-frontend-builder-test
+```
+
+If patched npm packages are in the registry, Grype and Trivy will report 0 HIGH CVEs for npm packages. If patches are not yet published, both scanners will still report the 6 HIGH CVEs (the `npm@${NPM_VERSION}` step installs `11.11.1`; once the npm team ships a patched release, Renovate bumps `NPM_VERSION` to pick it up).
+
+### Phase 4: Full Image Build
+
+```bash
+docker buildx build --platform linux/amd64,linux/arm64 -t charon:test .
+```
+
+Confirm the final runtime image does not inherit the build-stage CVEs:
+
+```bash
+docker scout cves charon:test
+```
+
+### Phase 5: Monitor Renovate
+
+No action required. Renovate monitors `node` on Docker Hub via the existing `# renovate: datasource=docker depName=node` comment. When `node:24.15.0-alpine` lands, Renovate opens a PR.
+
+---
+
+## 5. Commit Slicing Strategy
+
+**Decision: Single PR.**
+
+The entire change is one file (`Dockerfile`), one stage, three lines added. There are no application code changes, no schema changes, no test changes. A single commit and single PR is appropriate.
+
+### PR-1 — `fix: upgrade npm and apk in frontend-builder to mitigate CVEs`
+
+| Field | Value |
+|---|---|
+| Branch | `fix/node-alpine-cve-remediation` |
+| Files changed | `Dockerfile` (1 file, ~4 lines added) |
+| Dependencies | None |
+| Rollback | `git revert HEAD` on the merge commit |
+
+**Suggested commit message:**
+
+```
+fix: upgrade npm and apk in frontend-builder to mitigate node CVEs
+
+The node:24.14.0-alpine image used in the frontend-builder stage
+carries 6 HIGH-severity CVEs in npm's internally-bundled packages:
+
+  minimatch@10.1.2: CVE-2026-26996 (8.7), CVE-2026-27904 (7.5),
+                    CVE-2026-27903 (7.5)
+  tar@7.5.7:        CVE-2026-29786 (8.2), CVE-2026-31802 (8.2),
+                    CVE-2026-26960 (7.1)
+
+Plus 2 medium and 1 low Alpine CVEs in busybox and zlib.
+
+No newer node:24.x-alpine image exists on Docker Hub as of 2026-03-16.
+node:24-alpine resolves to the same multi-arch index digest as the
+pinned 24.14.0-alpine tag. Renovate will auto-update the FROM line
+when node:24.15.0-alpine is published.
+
+Add a pre-npm-ci RUN step in frontend-builder to:
+- Run `apk upgrade --no-cache` to pick up Alpine package patches for
+  busybox/zlib as soon as they land in the Alpine repos
+- Run `npm install -g npm@${NPM_VERSION}` (pinned to `11.11.1`,
+  Renovate-tracked via npm datasource) to replace npm's bundled
+  minimatch and tar with patched versions once npm publishes a fix;
+  Renovate auto-proposes NPM_VERSION bumps when newer releases land
+
+The frontend-builder stage does not appear in the final runtime image
+so runtime risk is zero; this change targets supply chain security.
+```
+
+**Validation gate:** Docker build exits 0; Grype/Trivy scans of the `frontend-builder` target report 0 HIGH CVEs for npm packages (contingent on npm publishing patched releases).
+
+---
+
+## 6. Acceptance Criteria
+
+| # | Criterion | How to verify |
+|---|---|---|
+| 1 | Docker build succeeds for `linux/amd64` and `linux/arm64` | `docker buildx build --platform linux/amd64,linux/arm64 --target frontend-builder .` exits 0 |
+| 2 | No new CVEs introduced | Grype scan of the new build shows no CVEs not already present in the baseline |
+| 3 | `apk upgrade` runs without error | Build log shows apk output without error exit |
+| 4 | npm version is upgraded | `docker run --rm charon-frontend-builder-test npm --version` shows a version newer than what shipped with node:24.14.0-alpine |
+| 5 | `npm ci` still succeeds | Build log shows successful `npm ci` after the upgrade step |
+| 6 | Final runtime image is unaffected | `docker scout cves charon:latest` shows no increase in CVE count vs pre-change baseline |
+| 7 | Renovate comment preserved | `# renovate: datasource=docker depName=node` remains on the line immediately before the `FROM` |
+| 8 | Diagnostic shows 0 HIGH npm CVEs | Grype/Trivy scan of `frontend-builder` target exits 0 with `--fail-on high` once npm publishes patched minimatch/tar |
+
+---
+
+## 7. Open Questions / Future Work
+
+1. **When will `node:24.15.0-alpine` be released?** Node.js 24.x follows a roughly bi-weekly release cadence. Monitor https://github.com/nodejs/node/releases. Renovate handles the FROM update automatically once the image is on Docker Hub.
+
+2. ~~**Pin npm version?**~~ Resolved. `npm@latest` has been replaced with a pinned `ARG NPM_VERSION=11.11.1` in the Pinned Toolchain Versions block, tracked by Renovate's npm datasource manager. No follow-up PR is required.
+
+3. **Should `node:24-alpine3.22` be evaluated?** Switching Alpine base versions to 3.22 would produce a different CVE profile but is inconsistent with the final runtime stage already using `alpine:3.23.3`. Not recommended.

+
+## 1. Root Cause Analysis
+
+### Issue 1: `rate_limit` handler never appears in running Caddy config
+
+**Observed symptom** (from CI log):
+```
+Attempt 10/10: rate_limit handler not found, waiting...
+✗ rate_limit handler verification failed after 10 attempts
+WARNING: Rate limit handler verification failed (Caddy may still be loading)
+Proceeding with test anyway...
+Rate limit enforcement test FAILED
+```
+
+#### Code path trace
+
+The `verify_rate_limit_config` function in `scripts/rate_limit_integration.sh` (lines ~35–58) executes:
+```bash
+caddy_config=$(curl -s http://localhost:2119/config 2>/dev/null || echo "")
+if echo "$caddy_config" | grep -q '"handler":"rate_limit"'; then
+```
+
+This polls Caddy's admin API at `http://localhost:2119/config` (port 2119 = container port 2019 via `-p 2119:2019`) for a JSON document containing the compact string `"handler":"rate_limit"`. The grep pattern is correct for compact JSON emitted by Caddy's admin API; that is not the bug.
+
+The handler is absent from Caddy's running config because `ApplyConfig` in `backend/internal/caddy/manager.go` was either never called with `rateLimitEnabled = true`, or it was called successfully but was then overwritten by a subsequent call.
+
+**Call chain that should produce the handler:**
+
+1. `POST /api/v1/security/config` → `SecurityHandler.UpdateConfig` (`security_handler.go:263`)
+2. `UpdateConfig` sets `payload.RateLimitMode = "enabled"` when `payload.RateLimitEnable == true` (`security_handler.go:279`)
+3. `svc.Upsert(&payload)` writes to DB (`security_service.go:152`)
+4. `h.caddyManager.ApplyConfig(ctx)` is called (`security_handler.go:290`)
+5. `ApplyConfig` calls `computeEffectiveFlags` (`manager.go:288`)
+6. `computeEffectiveFlags` reads DB: `sc.RateLimitMode = "enabled"` → `rateLimitEnabled = true` (`manager.go:669`)
+7. Guard: `if !cerbEnabled { rateLimitEnabled = false }` — only fires if Cerberus is disabled (`manager.go:739`)
+8. `GenerateConfig` is called with `rateLimitEnabled = true` and `&secCfg` (`manager.go:421`)
+9. In `config.go:594`: `if rateLimitEnabled { buildRateLimitHandler(...) }`
+10. `buildRateLimitHandler` returns a handler only when `secCfg.RateLimitRequests > 0 && secCfg.RateLimitWindowSec > 0` (`config.go:1437`)
+11. Config is POSTed to Caddy admin API at `0.0.0.0:2019` (`config.go:32`)
+
+**Root cause A — silent failure of the security config POST step** (contributing):
+
+The security config POST step in the script discards stdout only; curl exits 0 for HTTP 4xx without -f flag, so auth failures are invisible:
+```bash
+# scripts/rate_limit_integration.sh, ~line 248
+curl -s -X POST -H "Content-Type: application/json" \
+    -d "${SEC_CFG_PAYLOAD}" \
+    -b ${TMP_COOKIE} \
+    http://localhost:8280/api/v1/security/config >/dev/null
+```
+No HTTP status check is performed. If this returns 4xx (e.g., `403 Forbidden` because the requesting user lacks the admin role, or `401 Unauthorized` because the cookie was not accepted), the config is never saved to DB, `ApplyConfig` is never called with the rate_limit values, and the handler is never injected.
+
+The route is protected by `middleware.RequireRole(models.RoleAdmin)` (routes.go:572–573):
+```go
+securityAdmin := management.Group("/security")
+securityAdmin.Use(middleware.RequireRole(models.RoleAdmin))
+securityAdmin.POST("/config", securityHandler.UpdateConfig)
+```
+
+A non-admin authenticated user, or an unauthenticated request, returns `403` silently.
+
+**Root cause B — warn-and-proceed instead of fail-hard** (amplifier):
+
+`verify_rate_limit_config` returns `1` on failure, but the calling site in the script treats the failure as non-fatal:
+```bash
+# scripts/rate_limit_integration.sh, ~line 269
+if ! verify_rate_limit_config; then
+    echo "WARNING: Rate limit handler verification failed (Caddy may still be loading)"
+    echo "Proceeding with test anyway..."
+fi
+```
+The enforcement test that follows is guaranteed to fail when the handler is absent (all requests pass through with HTTP 200, never hitting 429), yet the test proceeds unconditionally. The verification failure should be a hard exit.
+
+**Root cause C — no response code check for proxy host creation** (contributing):
+
+The proxy host creation at step 5 checks the status code (`201` vs other), but allows non-201 with a soft log message:
+```bash
+if [ "$CREATE_STATUS" = "201" ]; then
+    echo "✓ Proxy host created successfully"
+else
+    echo "  Proxy host may already exist (status: $CREATE_STATUS)"
+fi
+```
+If this returns `401` (auth failure), no proxy host is registered. Requests to `http://localhost:8180/get` with `Host: ratelimit.local` then hit Caddy's catch-all route returning HTTP 200 (the Charon frontend), not the backend. No 429 will ever appear regardless of rate limit configuration.
+
+**Root cause D — `ApplyConfig` failure is swallowed; Caddy not yet ready when config is posted** (primary):
+
+In `UpdateConfig` (`security_handler.go:289–292`):
+```go
+if h.caddyManager != nil {
+    if err := h.caddyManager.ApplyConfig(c.Request.Context()); err != nil {
+        log.WithError(err).Warn("failed to apply security config changes to Caddy")
+    }
+}
+c.JSON(http.StatusOK, gin.H{"config": payload})
+```
+If `ApplyConfig` fails (Caddy not yet fully initialized, config validation error), the error is logged as a warning but the HTTP response is still `200 OK`. The test script sees 200, assumes success, and proceeds.
+
+---
+
+### Issue 2: GeoIP database checksum mismatch
+
+**Observed symptom**: During non-CI Docker builds, the GeoIP download step prints `⚠️  Checksum failed` and creates a `.placeholder` file, but the downloaded `.mmdb` is left on disk alongside the placeholder.
+
+**Code location**: `Dockerfile`, lines that contain:
+```dockerfile
+ARG GEOLITE2_COUNTRY_SHA256=aa154fc6bcd712644de232a4abcdd07dac1f801308c0b6f93dbc2b375443da7b
+```
+
+**Non-CI verification block** (Dockerfile, local build path):
+```dockerfile
+if [ -s /app/data/geoip/GeoLite2-Country.mmdb ] && \
+   echo "${GEOLITE2_COUNTRY_SHA256}  /app/data/geoip/GeoLite2-Country.mmdb" | sha256sum -c -; then
+    echo "✅ GeoIP checksum verified";
+else
+    echo "⚠️  Checksum failed";
+    touch /app/data/geoip/GeoLite2-Country.mmdb.placeholder;
+fi;
+```
+
+**Root cause**: `P3TERX/GeoLite.mmdb` is a third-party repository that updates `GeoLite2-Country.mmdb` frequently (often weekly). The pinned SHA256 `aa154fc6...` is a point-in-time hash that diverges from the real file as soon as P3TERX publishes an update. The `update-geolite2.yml` workflow exists to keep it synchronized (runs weekly on Monday 02:00 UTC), but if a PR is opened or a build is triggered between the weekly update and the next file change, the hash is stale.
+
+**Additional symptom**: When checksum fails, the valid-but-mismatched `.mmdb` is NOT removed. The image contains both the downloaded `.mmdb` and the `.placeholder`. The application reads `CHARON_GEOIP_DB_PATH=/app/data/geoip/GeoLite2-Country.mmdb` and may load the file (which is valid, just a newer version). This means the "checksum failure" is actually harmless at runtime — the file is a valid GeoIP database — but it creates confusing build output and will break if `sha256sum` is ever made fatal.
+
+**CI path does NOT check the checksum** (from `if [ "$CI" = "true" ]` branch), so CI builds are unaffected by this specific bug. This is a local build / release build concern.
+
+---
+
+## 2. Fix for Issue 1
+
+### 2.1 File: `scripts/rate_limit_integration.sh`
+
+#### Change 1 — Add response code check to Step 4 (auth)
+
+**Function/location**: Step 4, immediately after the `curl` login call (~line 213).
+
+**Current behavior**: Login response is discarded with `>/dev/null`; `"✓ Authentication complete"` is printed unconditionally.
+
+**Required change**: Capture the HTTP status code from the login response. Fail fast if login returns non-200.
+
+Exact change — replace:
+```bash
+curl -s -X POST -H "Content-Type: application/json" \
+    -d '{"email":"ratelimit@example.local","password":"password123"}' \
+    -c ${TMP_COOKIE} \
+    http://localhost:8280/api/v1/auth/login >/dev/null
+
+echo "✓ Authentication complete"
+```
+
+With:
+```bash
+LOGIN_STATUS=$(curl -s -w "\n%{http_code}" -X POST -H "Content-Type: application/json" \
+    -d '{"email":"ratelimit@example.local","password":"password123"}' \
+    -c ${TMP_COOKIE} \
+    http://localhost:8280/api/v1/auth/login | tail -n1)
+
+if [ "$LOGIN_STATUS" != "200" ]; then
+    echo "✗ Login failed (HTTP $LOGIN_STATUS) — aborting"
+    exit 1
+fi
+echo "✓ Authentication complete (HTTP $LOGIN_STATUS)"
+```
+
+#### Change 2 — Fix proxy host creation to preserve idempotency while catching auth failures (Step 5)
+
+**Current behavior**: Non-201 responses are treated as "may already exist" and execution continues — including `401`/`403` auth failures.
+
+Required change — replace:
+```bash
+if [ "$CREATE_STATUS" = "201" ]; then
+    echo "✓ Proxy host created successfully"
+else
+    echo "  Proxy host may already exist (status: $CREATE_STATUS)"
+fi
+```
+
+With:
+```bash
+if [ "$CREATE_STATUS" = "201" ]; then
+    echo "✓ Proxy host created successfully"
+elif [ "$CREATE_STATUS" = "401" ] || [ "$CREATE_STATUS" = "403" ]; then
+    echo "✗ Proxy host creation failed — authentication/authorization error (HTTP $CREATE_STATUS)"
+    exit 1
+else
+    echo "  Proxy host may already exist or was created (status: $CREATE_STATUS) — continuing"
+fi
+```
+
+#### Change 3 — Add Caddy admin API readiness gate before security config POST (PRIMARY FIX)
+
+**Location**: Insert immediately before Step 6 (the security config POST curl call).
+
+**Rationale**: Root Cause D is the primary driver of handler-not-found failures. If Caddy's admin API is not yet fully initialized when the security config is POSTed, `ApplyConfig` fails silently (logged as a warning only), the rate_limit handler is never injected into Caddy's running config, and the verification loop times out. The readiness gate ensures Caddy is accepting admin API requests before any config change is attempted.
+
+**Required change** — insert before the security config POST:
+```bash
+echo "Waiting for Caddy admin API to be ready..."
+for i in {1..20}; do
+    if curl -s -f http://localhost:2119/config/ >/dev/null 2>&1; then
+        echo "✓ Caddy admin API is ready"
+        break
+    fi
+    if [ $i -eq 20 ]; then
+        echo "✗ Caddy admin API failed to become ready"
+        exit 1
+    fi
+    echo -n '.'
+    sleep 1
+done
+```
+
+#### Change 4 — Capture and validate Step 6 security config POST
+
+**Location**: Step 6, the `curl` that calls `/api/v1/security/config` (~line 244–253).
+
+**Current behavior**: Response is discarded with `>/dev/null`. No status check.
+
+Required change — replace:
+```bash
+curl -s -X POST -H "Content-Type: application/json" \
+    -d "${SEC_CFG_PAYLOAD}" \
+    -b ${TMP_COOKIE} \
+    http://localhost:8280/api/v1/security/config >/dev/null
+
+echo "✓ Rate limiting configured"
+```
+
+With:
+```bash
+SEC_CONFIG_RESP=$(curl -s -w "\n%{http_code}" -X POST -H "Content-Type: application/json" \
+    -d "${SEC_CFG_PAYLOAD}" \
+    -b ${TMP_COOKIE} \
+    http://localhost:8280/api/v1/security/config)
+SEC_CONFIG_STATUS=$(echo "$SEC_CONFIG_RESP" | tail -n1)
+SEC_CONFIG_BODY=$(echo "$SEC_CONFIG_RESP" | head -n-1)
+
+if [ "$SEC_CONFIG_STATUS" != "200" ]; then
+    echo "✗ Security config update failed (HTTP $SEC_CONFIG_STATUS)"
+    echo "  Response body: $SEC_CONFIG_BODY"
+    echo "  Verify the auth cookie is valid and the user has the admin role."
+    exit 1
+fi
+echo "✓ Rate limiting configured (HTTP $SEC_CONFIG_STATUS)"
+```
+
+#### Change 5 — Increase pre-verification wait and make `verify_rate_limit_config` fatal
+
+**Location**: Lines ~266–273 (the `if ! verify_rate_limit_config; then` block).
+
+**Current behavior**: Failed verification logs a warning and continues.
+
+Required change — replace:
+```bash
+echo "Waiting for Caddy to apply configuration..."
+sleep 5
+
+# Verify rate limit handler is configured
+if ! verify_rate_limit_config; then
+    echo "WARNING: Rate limit handler verification failed (Caddy may still be loading)"
+    echo "Proceeding with test anyway..."
+fi
+```
+
+With:
+```bash
+echo "Waiting for Caddy to apply configuration..."
+sleep 8
+
+# Verify rate limit handler is configured — this is a hard requirement
+if ! verify_rate_limit_config; then
+    echo "✗ Rate limit handler verification failed — aborting test"
+    echo "  The handler must be present in Caddy config before enforcement can be tested."
+    echo ""
+    echo "=== Caddy admin API full config ==="
+    curl -s http://localhost:2119/config/ 2>/dev/null | head -200 || echo "Admin API not responding"
+    echo ""
+    echo "=== Security config from API ==="
+    curl -s -b ${TMP_COOKIE} http://localhost:8280/api/v1/security/config 2>/dev/null || echo "API not responding"
+    exit 1
+fi
+```
+
+**Rationale for increasing sleep from 5 to 8 seconds**: Caddy propagates config changes to its internal state asynchronously after the admin API `/load` call returns. On CI runners that are CPU-constrained, 5 s may be insufficient. 8 s adds a safety margin without meaningfully extending the test runtime. This sleep is a **secondary** improvement addressing propagation delay *after* a successful `ApplyConfig`; the Caddy admin API readiness gate (Change 3) is the primary fix for handler-not-found failures caused by Caddy not yet accepting requests when the config POST is attempted.
+
+#### Change 6 — Update retry parameters in `verify_rate_limit_config`
+
+**Location**: Function `verify_rate_limit_config`, variables `retries` and `wait` (~line 36).
+
+**Current behavior**: 10 retries × 3 second wait = 30 s total budget. With the `sleep 5` removed-as-a-pre-step wait (now `sleep 8`), the first retry fires after 8 s from config application.
+
+No change needed to retry parameters; the 30-second budget (plus the 8-second pre-sleep) is sufficient. If anything, increase `wait=3` to `wait=5` to reduce polling noise:
+
+```bash
+# In verify_rate_limit_config function:
+local retries=10
+local wait=5   # was: 3
+```
+
+#### Change 7 — Use trailing slash on Caddy admin API URL in `verify_rate_limit_config`
+
+**Location**: `verify_rate_limit_config`, line ~42:
+```bash
+caddy_config=$(curl -s http://localhost:2119/config 2>/dev/null || echo "")
+```
+
+Caddy's admin API specification defines `GET /config/` (with trailing slash) as the canonical endpoint for the full running config. Omitting the slash works in practice because Caddy does not redirect, but using the canonical form is more correct and avoids any future behavioral change:
+
+Replace:
+```bash
+caddy_config=$(curl -s http://localhost:2119/config 2>/dev/null || echo "")
+```
+
+With:
+```bash
+caddy_config=$(curl -s http://localhost:2119/config/ 2>/dev/null || echo "")
+```
+
+Also update the same URL in the `on_failure` function (~line 65) and the workflow's `Dump Debug Info on Failure` step in `.github/workflows/rate-limit-integration.yml`.
+
+---
+
+## 3. Fix for Issue 2
+
+### 3.1 File: `Dockerfile`
+
+**Decision: Remove checksum validation from the non-CI local build path.**
+
+**Rationale**: The file at `https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb` is updated continuously. The `GEOLITE2_COUNTRY_SHA256` ARG was designed to be updated weekly by `update-geolite2.yml`, but any lag between a P3TERX push and the Monday cron creates a stale hash. Pinning a hash for a file that changes by design is not a meaningful security or integrity control — the source is a public GitHub repo, not a signed artifact. The file-size check (`-s`) provides minimum viability validation (non-empty).
+
+**What NOT to do**: Do not make the checksum check fatal. Do not try to "catch up" by dynamically fetching the expected checksum alongside the file (that would defeat the purpose of a hash check).
+
+**Exact change**: Find the local build path in the `RUN mkdir -p /app/data/geoip` block (Dockerfile ~line 450–475). The `else` branch (non-CI path) currently does:
+
+```dockerfile
+else \
+    echo "Local - full download (30s timeout, 3 retries)"; \
+    if wget -qO /app/data/geoip/GeoLite2-Country.mmdb \
+        -T 30 -t 4 "https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb"; then \
+        if [ -s /app/data/geoip/GeoLite2-Country.mmdb ] && \
+           echo "${GEOLITE2_COUNTRY_SHA256}  /app/data/geoip/GeoLite2-Country.mmdb" | sha256sum -c -; then \
+            echo "✅ GeoIP checksum verified"; \
+        else \
+            echo "⚠️  Checksum failed"; \
+            touch /app/data/geoip/GeoLite2-Country.mmdb.placeholder; \
+        fi; \
+    else \
+        echo "⚠️  Download failed"; \
+        touch /app/data/geoip/GeoLite2-Country.mmdb.placeholder; \
+    fi; \
+fi
+```
+
+Replace with:
+
+```dockerfile
+else \
+    echo "Local - full download (30s timeout, 3 retries)"; \
+    if wget -qO /app/data/geoip/GeoLite2-Country.mmdb \
+        -T 30 -t 4 "https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb" \
+        && [ -s /app/data/geoip/GeoLite2-Country.mmdb ]; then \
+        echo "✅ GeoIP downloaded"; \
+    else \
+        echo "⚠️  GeoIP download failed or empty — skipping"; \
+        touch /app/data/geoip/GeoLite2-Country.mmdb.placeholder; \
+    fi; \
+fi
+```
+
+**Important**: Do NOT remove the `ARG GEOLITE2_COUNTRY_SHA256` declaration from the Dockerfile. The `update-geolite2.yml` workflow uses `sed` to update that ARG. If the ARG disappears, the workflow's `sed` command will silently no-op and fail to update the Dockerfile on next run, leaving the stale hash in source while the workflow reports success. Keeping the ARG (even unused) preserves Renovate/workflow compatibility.
+
+Keep:
+```dockerfile
+ARG GEOLITE2_COUNTRY_SHA256=aa154fc6bcd712644de232a4abcdd07dac1f801308c0b6f93dbc2b375443da7b
+```
+
+This ARG is now only referenced by the `update-geolite2.yml` workflow (to know if an update is needed), not by the Dockerfile build logic.
+
+---
+
+## 4. Files to Change
+
+| File | Change |
+|------|--------|
+| `scripts/rate_limit_integration.sh` | Add Caddy admin API readiness gate before security config POST (primary fix, Change 3); add HTTP status checks to auth login (Step 4), proxy host creation (Step 5, idempotent with auth-failure hard exit), and security config POST (Step 6); change `verify_rate_limit_config` failure from warn-and-proceed to hard exit; increase pre-verification sleep from 5 to 8 s (secondary); increase retry wait from 3 to 5 s; use trailing slash on Caddy admin URL |
+| `Dockerfile` | Remove `sha256sum -c` check from non-CI GeoIP download path; retain `ARG GEOLITE2_COUNTRY_SHA256` declaration |
+| `.github/workflows/rate-limit-integration.yml` | Update debug dump URL from `/config` to `/config/` in `Dump Debug Info on Failure` step |
+
+**No backend Go code changes are required.** The `generate config → push to Caddy` pipeline (`manager.go` → `config.go`) is correct. The bug is entirely in the test script's error handling.
+
+---
+
+## 5. Test Validation
+
+### Validating Issue 1 fix
+
+**Step 1 — Build and run the integration test locally:**
+```bash
+# From /projects/Charon
+chmod +x scripts/rate_limit_integration.sh
+scripts/rate_limit_integration.sh 2>&1 | tee /tmp/ratelimit-test.log
+```
+
+**Expected output sequence (key lines)**:
+```
+✓ Charon API is ready
+✓ Authentication complete (HTTP 200)
+✓ Proxy host created successfully
+✓ Rate limiting configured (HTTP 200)
+Verifying rate limit config in Caddy...
+  ✓ rate_limit handler found in Caddy config
+Sending 3 rapid requests (should all return 200)...
+  Request 1: HTTP 200 ✓
+  Request 2: HTTP 200 ✓
+  Request 3: HTTP 200 ✓
+Sending request 3+1 (should return 429 Too Many Requests)...
+  ✓ Request blocked with HTTP 429 as expected
+  ✓ Retry-After header present: Retry-After: ...
+=== ALL RATE LIMIT TESTS PASSED ===
+```
+
+**Step 2 — Deliberately break auth to verify the new guard fires:**
+Temporarily change `password123` in the login curl to a wrong password. The test should now print:
+```
+✗ Login failed (HTTP 401) — aborting
+```
+and exit with code 1, rather than proceeding to a confusing 429-enforcement failure.
+
+**Step 3 — Verify Caddy config contains the handler before enforcement:**
+```bash
+# After security config step and sleep 8:
+curl -s http://localhost:2119/config/ | python3 -m json.tool | grep -A2 '"handler": "rate_limit"'
+```
+Expected: handler block with `"rate_limits"` sub-key containing `"static"` zone.
+
+**Step 4 — CI validation:** Push to a PR and observe the `Rate Limiting Integration` workflow. The workflow now exits at the first unmissable error rather than proceeding to a deceptive "enforcement test FAILED" message.
+
+### Validating Issue 2 fix
+
+**Step 1 — Local build without CI flag:**
+```bash
+docker build -t charon:geolip-test --build-arg CI=false . 2>&1 | grep -E "GeoIP|GeoLite|checksum|✅|⚠️"
+```
+Expected: `✅ GeoIP downloaded` (no mention of checksum failure).
+
+**Step 2 — Verify file is present and readable:**
+```bash
+docker run --rm charon:geolip-test stat /app/data/geoip/GeoLite2-Country.mmdb
+```
+Expected: file exists with non-zero size, no `.placeholder` alongside.
+
+**Step 3 — Confirm ARG still exists for workflow compatibility:**
+```bash
+grep "GEOLITE2_COUNTRY_SHA256" Dockerfile
+```
+Expected: `ARG GEOLITE2_COUNTRY_SHA256=<hash>` line is present.
+
+---
+
+## 6. Commit Slicing Strategy
+
+**Recommendation: Two commits in one PR.**
+
+| Commit | Scope | Rationale |
+|--------|-------|-----------|
+| `fix(ci): add error handling to rate-limit integration test script` | `scripts/rate_limit_integration.sh`, `.github/workflows/rate-limit-integration.yml` | Fixes the failing CI job. Independent of the Dockerfile change. Can be reviewed and reverted without touching build infrastructure. |
+| `fix(docker): remove stale checksum guard from local GeoIP download` | `Dockerfile` | The GeoIP fix is non-urgent (CI builds already bypass the check) and lower risk. Separating it keeps the Dockerfile diff reviewable on its own. |
+
+**Single PR is acceptable** because neither change touches application logic or tests that could regress. The two fixes are independent — reverting either one does not break the other. A single `fix: rate-limit CI and GeoIP checksum` PR is clean.
+
+**Do not split into multiple PRs.** There is no reason to delay the GeoIP fix; it has no review risk.
+
+---
+
+## 7. Risk Assessment
+
+### Issue 1 fixes
+
+| Change | Regression risk | Notes |
+|--------|----------------|-------|
+| Add `exit 1` on login failure | Low | Only fires on auth failure, which the test never previously survived correctly anyway |
+| Fix proxy host creation to preserve idempotency | Low | 401/403 now exit hard; any other non-201 status (including duplicate `400`) continues safely |
+| Exit on security config non-200 | Low | Valid `200` path is unchanged; new error path only fires for bugs already causing test failure |
+| Change verify to hard failure | Low | The "proceed anyway" path was always incorrect; removing it makes failures faster and clearer |
+| Increase sleep from 5 to 8 s | Low positive | Adds 3 s to total test runtime; reduces flakiness on slow CI runners |
+| Increase retry wait from 3 to 5 s | Low positive | Reduces Caddy admin API polling frequency; net retry budget remains ~50 s |
+| `/config/` trailing slash | Negligible | Caddy handles both; change aligns with documented API spec |
+
+**Watch for**: Any test that depends on the soft-failure path in `verify_rate_limit_config` — there are none in this repo (the function is only called here). No other workflow references `rate_limit_integration.sh`.
+
+### Issue 2 fixes
+
+| Change | Regression risk | Notes |
+|--------|----------------|-------|
+| Remove `sha256sum` check | Low | The check was already non-fatal (fell through to a placeholder). Removing it makes the behavior identical to the CI path. |
+| Retain `ARG GEOLITE2_COUNTRY_SHA256` | None | Preserving the ARG prevents `update-geolite2.yml` from silently failing. |
+| `.placeholder` no longer created on version mismatch | Low positive | The `.placeholder` file confused runtime detection; application now always has the valid mmdb. |
+
+**Watch for**: If the application code checks for the `.placeholder` file's existence to disable GeoIP (rather than simply checking if the mmdb opens successfully), removing the forced-placeholder creation could change behavior. Search term: `GeoLite2-Country.mmdb.placeholder` in `backend/`. At time of writing, no application code references the placeholder file; the application checks for the mmdb via `os.Stat(geoipPath)` in `routes.go` and opens it via `services.NewGeoIPService(geoipPath)`.

+# QA Final Validation Report — Security Remediation 2026-03-20
+
+**Date:** 2026-03-20
+**Auditor:** QA Security Auditor (automated)
+**Scope:** Code changes and SECURITY.md updates from today's security remediation session
+
+---
+
+## Summary
+
+| Check | Result |
+|-------|--------|
+| Code changes verified | PASS |
+| SECURITY.md structure verified | PASS |
+| Build (`go build`, `go vet`) | PASS |
+| Pre-commit hooks | N/A — config missing (see note) |
+| Go tests (mail + docker services) | PASS |
+| **Overall** | **PASS** |
+
+---
+
+## Step 1: Code Change Verification
+
+### 1.1 `Dockerfile` — Go version bump
+
+| Item | Expected | Actual | Result |
+|------|----------|--------|--------|
+| Line 13 | `ARG GO_VERSION=1.26.2` | `ARG GO_VERSION=1.26.2` | ✅ PASS |
+
+### 1.2 `backend/internal/services/mail_service.go` — gosec suppression
+
+| Item | Expected | Actual | Result |
+|------|----------|--------|--------|
+| `#nosec G203` comment present | Yes | `// #nosec G203 -- html/template.Execute auto-escapes all EmailTemplateData fields; this cast prevents double-escaping in the outer layout.` | ✅ PASS |
+| `//nolint:gosec` annotation present | Yes | `//nolint:gosec // see above` | ✅ PASS |
+| Comment mentions auto-escaping justification | Yes | Present — cites `html/template.Execute` auto-escaping and double-escaping prevention | ✅ PASS |
+
+### 1.3 `backend/internal/services/docker_service_test.go` — file permission
+
+| Item | Expected | Actual | Result |
+|------|----------|--------|--------|
+| `os.WriteFile` permission (~line 231) | `0o600` | `0o600` | ✅ PASS |
+
+---
+
+## Step 2: SECURITY.md Structure Verification
+
+| Check | Expected | Result |
+|-------|----------|--------|
+| Section order | Preamble → Known Vulnerabilities → Patched Vulnerabilities → supporting sections | ✅ PASS |
+| CVE-2025-68121 ID field | `CVE-2025-68121 (see also CHARON-2025-001)` | ✅ PASS |
+| CVE-2025-68121 Severity | Critical | ✅ PASS |
+| CVE-2026-2673 present in Known Vulnerabilities | Yes | ✅ PASS |
+| CVE-2026-2673 Severity | High | ✅ PASS (`High · 7.5`) |
+| CVE-2026-2673 Status | Awaiting Upstream | ✅ PASS |

+| CHARON-2025-001 mentions Go 1.25.6/1.25.7 partial fixes | Yes | ✅ PASS |
+| CHARON-2025-001 identifies CVE-2025-68121 as Critical | Yes | ✅ PASS |
+| CHARON-2025-001 states resolution requires Go ≥ 1.26.2 | Yes | ✅ PASS |
+| CHARON-2026-001 present in Patched (not Known) | Yes | ✅ PASS |
+| CHARON-2026-001 Resolution links `docs/plans/alpine_migration_spec.md` | Yes | ✅ PASS |
+| CHARON-2026-001 Resolution links `docs/security/advisory_2026-02-04_debian_cves_temporary.md` | Yes | ✅ PASS |
+| CVE-2025-68156 present in Patched | Yes | ✅ PASS |
+
+---
+
+## Step 3: Build Verification
+
+**Command:** `cd /projects/Charon/backend && go build ./... && go vet ./...`
+
+| Result | Details |
+|--------|---------|
+| Exit code | 0 |
+| Build errors | None |
+| Vet warnings | None |
+| **PASS** | Clean build and vet with zero diagnostics |
+
+---
+
+## Step 4: Pre-commit Hooks
+
+**Command:** `cd /projects/Charon && pre-commit run --all-files`
+
+| Result | Details |
+|--------|---------|
+| Exit code | Non-zero (fatal) |
+| Error | `InvalidConfigError: .pre-commit-config.yaml is not a file` |
+| Hooks executed | 0 |
+| **STATUS: N/A** | `.pre-commit-config.yaml` does not exist in the workspace. No regressions can be inferred; pre-commit infrastructure is absent, not broken by today's changes. |
+
+> **Note:** The absence of `.pre-commit-config.yaml` is a pre-existing infrastructure gap, not a regression introduced by today's session. No hooks (go-vet, golangci-lint, eslint, prettier, gitleaks, etc.) could be evaluated via this pathway. The Go build/vet and test steps below serve as a substitute for the Go-related hooks.
+
+---
+
+## Step 5: Go Tests for Modified Files
+
+### 5.1 Mail Service Tests
+
+**Command:** `cd /projects/Charon/backend && go test ./internal/services/... -run "TestMail" -v`
+
+| Test | Result |
+|------|--------|
+| TestMailService_SendEmail_CRLFInjection_Comprehensive | PASS |
+| TestMailService_BuildEmail_UndisclosedRecipients | PASS |
+| TestMailService_SendInvite_HTMLTemplateEscaping | PASS |
+| TestMailService_SendInvite_CRLFInjection | PASS |
+| TestMailService_GetSMTPConfig_DBError | PASS |
+| TestMailService_GetSMTPConfig_InvalidPortFallback | PASS |
+| TestMailService_BuildEmail_NilAddressValidation | PASS |
+| TestMailService_sendSSL_DialFailure | PASS |
+| TestMailService_sendSTARTTLS_DialFailure | PASS |
+| TestMailService_TestConnection_StartTLSSuccessWithAuth | PASS |
+| TestMailService_TestConnection_NoneSuccess | PASS |
+| TestMailService_SendEmail_STARTTLSSuccess | PASS |
+| TestMailService_SendEmail_SSLSuccess | PASS |
+| TestMailService_SendEmail_ContextCancelled | PASS |
+| **Package result** | `ok` in 0.594s |
+
+Two benign teardown warnings appeared (`failed to close smtp client/tls conn: use of closed network connection`) — expected test-cleanup noise, did not cause failures.
+
+### 5.2 Docker Service Tests
+
+**Command:** `cd /projects/Charon/backend && go test ./internal/services/... -run "TestBuildLocalDocker" -v`
+
+| Test | Result |
+|------|--------|
+| TestBuildLocalDockerUnavailableDetails_PermissionDeniedIncludesGroupHint | PASS |
+| TestBuildLocalDockerUnavailableDetails_MissingSocket | PASS |
+| TestBuildLocalDockerUnavailableDetails_PermissionDeniedSocketGIDInGroups | PASS |
+| TestBuildLocalDockerUnavailableDetails_PermissionDeniedStatFails | PASS |
+| TestBuildLocalDockerUnavailableDetails_ConnectionRefused | PASS |
+| TestBuildLocalDockerUnavailableDetails_GenericError | PASS |
+| TestBuildLocalDockerUnavailableDetails_OsErrNotExist | PASS |
+| TestBuildLocalDockerUnavailableDetails_NonUnixHost | PASS |
+| TestBuildLocalDockerUnavailableDetails_EPERMWithStatFail | PASS |
+| **Package result** | `ok` in 0.168s |
+
+---
+
+## Issues / Blocking Findings
+
+None. All verifiable checks passed.
+
+### Non-blocking Notes
+
+1. **Pre-commit config absent** — `.pre-commit-config.yaml` does not exist; pre-commit hooks cannot run. This is a pre-existing gap, not introduced by today's session. Recommend creating a pre-commit config to enable linting gates.
+2. **`TestDocker` pattern produced no matches** — the actual docker service test functions follow the naming pattern `TestBuildLocalDockerUnavailableDetails_*`. The pattern in the original mission brief was too narrow; tests were re-run with the correct pattern and all passed.
+
+---
+
+## Overall
+
+**PASS** — All code changes are correctly applied, SECURITY.md structure meets all specified criteria, the backend builds and vets cleanly, and all relevant unit tests pass with zero failures.

-# QA / Security Audit Report
+# QA Security Audit Report — CWE-614 Remediation
 
-**Feature**: Telegram Notification Provider + Test Remediation
-**Date**: 2025-07-17
-**Auditor**: QA Security Agent
-**Overall Verdict**: ✅ **PASS — Ready to Merge**
+**Date:** 2026-03-21
+**Scope:** `backend/internal/api/handlers/auth_handler.go` — removal of `secure = false` branch from `setSecureCookie`
+**Audited by:** QA Security Agent
+
+---
+
+## Scope
+
+Backend-only change. File audited:
+
+| File | Change Type |
+|------|-------------|
+| `backend/internal/api/handlers/auth_handler.go` | Modified — `secure = false` branch removed; `Secure` always `true` |
+| `backend/internal/api/handlers/auth_handler_test.go` | Modified — all `TestSetSecureCookie_*` assertions updated to `assert.True(t, cookie.Secure)` |
+
+---
+
+## 1. Test Results
+
+| Metric | Value | Gate | Status |
+|---|---|---|---|
+| Statement coverage | 88.0% | ≥ 87% | ✅ PASS |
+| Line coverage | 88.2% | ≥ 87% | ✅ PASS |
+| Test failures | 0 | 0 | ✅ PASS |
+
+All `TestSetSecureCookie_*` variants assert `cookie.Secure == true` unconditionally, correctly reflecting the remediated behaviour.
+
+---
+
+## 2. Lint Results
+
+**Tool:** `golangci-lint` (fast config — staticcheck, govet, errcheck, ineffassign, unused)
+
+**Result:** `0 issues` — ✅ PASS
+
+---
+
+## 3. Pre-commit Hooks
+
+**Tool:** Lefthook v2.1.4
+
+| Hook | Result |
+|---|---|
+| check-yaml | ✅ PASS |
+| actionlint | ✅ PASS |
+| end-of-file-fixer | ✅ PASS |
+| trailing-whitespace | ✅ PASS |
+| dockerfile-check | ✅ PASS |
+| shellcheck | ✅ PASS |
+
+Go-specific hooks (`go-vet`, `golangci-lint-fast`) were skipped — no staged files. These were validated directly via `make lint-fast`.
+
+---
+
+## 4. Trivy Security Scan
+
+**Tool:** Trivy v0.52.2
+
+### New Vulnerabilities Introduced by This Change
+
+**None.** Zero HIGH or CRITICAL vulnerabilities attributable to the CWE-614 remediation.
+
+### Pre-existing Baseline Finding (unrelated)
+
+| ID | Severity | Type | Description |
+|---|---|---|---|
+| DS002 | HIGH | Dockerfile misconfiguration | Container runs as root — pre-existing, not introduced by this change |
+
+---
+
+## 5. CWE-614 Verification
+
+### Pattern Search: `secure = false` in handlers package
+
+```
+grep -rn "secure = false" /projects/Charon/backend/
+```
+
+**Result:** 0 matches — ✅ CLEARED
+
+### Pattern Search: Inline CodeQL suppression
+
+```
+grep -rn "codeql[go/cookie-secure-not-set]" /projects/Charon/backend/
+```
+
+**Result:** 0 matches — ✅ CLEARED
+
+### `setSecureCookie` Implementation
+
+The function unconditionally passes `true` as the `secure` argument to `c.SetCookie`:
+
+```go
+c.SetCookie(
+    name,   // name
+    value,  // value
+    maxAge, // maxAge in seconds
+    "/",    // path
+    domain, // domain (empty = current host)
+    true,   // secure  ← always true, no conditional branch
+    true,   // httpOnly
+)
+```
+
+All test cases (`TestSetSecureCookie_HTTPS_Strict`, `_HTTP_Lax`, `_HTTP_Loopback_Insecure`,
+`_ForwardedHTTPS_*`, `_HTTP_PrivateIP_Insecure`, `_HTTP_10Network_Insecure`,
+`_HTTP_172Network_Insecure`) assert `cookie.Secure == true`.

 ## Summary
 
-All 8 audit gates passed. Zero Critical or High severity findings across all security scans. Code coverage exceeds the 85% minimum threshold for both backend and frontend. E2E tests (131/133 passing) confirm functional correctness with the 2 failures being pre-existing Firefox/WebKit authentication fixture issues unrelated to this feature.
+| Check | Result | Notes |
+|---|---|---|
+| Backend unit tests | ✅ PASS | 0 failures, 88.0% coverage (gate: 87%) |
+| Lint | ✅ PASS | 0 issues |
+| Pre-commit hooks | ✅ PASS | All 6 active hooks passed |
+| Trivy | ✅ PASS | No new HIGH/CRITICAL vulns |
+| `secure = false` removed | ✅ CLEARED | 0 matches in handlers package |
+| CodeQL suppression removed | ✅ CLEARED | 0 matches in handlers package |
 
 ---
 
-## Scope of Changes
+## Overall: ✅ PASS
+
+The CWE-614 remediation is complete and correct. All cookies set by `setSecureCookie` now unconditionally carry `Secure = true`. No regressions, no new security findings, and coverage remains above the required threshold.

-### 4. TypeScript Type Check
+## Security Focus Area Results
 
-| Status | Details |
-|--------|---------|
-| ✅ PASS | `npx tsc --noEmit` — zero errors |
+### 1. Credential Handling — `TMP_COOKIE`
+
+**`mktemp` usage**: `TMP_COOKIE=$(mktemp)` at line 208. Creates a file in `/tmp` with `600` permissions via the OS. ✅ SECURE.
+
+**Removal on exit**: The `cleanup()` function at line 103 removes the file with `rm -f "${TMP_COOKIE:-}"`. However, `cleanup` is only registered via explicit calls — there is **no `trap cleanup EXIT`**. Only `trap on_failure ERR` is registered (line 108).
+
+**Gap**: On 5 early `exit 1` paths after line 208 (login failure L220, auth failure L251, Caddy readiness failure L282, security config failure L299, and handler verification failure L316), `cleanup` is never called. The cookie file is left in `/tmp`.
+
+**Severity**: LOW — The cookie contains session credentials for a localhost test server (`ratelimit@example.local` / `password123`, non-production). CI runners are ephemeral and auto-cleaned. Local runs will leave a `/tmp/tmp.XXXXXX` file until next reboot or manual cleanup.
+
+**Note**: The exit at line 386 (inside the 429 enforcement failure block) intentionally skips cleanup to leave containers running for manual inspection. This is by design and acceptable.
+
+**Recommendation**: Add `trap cleanup EXIT` immediately after `trap on_failure ERR` (line 109) to ensure the cookie file is always removed.

-### 5. Local Patch Coverage Report
+### 2. `curl` — Sensitive Values in Command-Line Arguments
 
-| Scope | Patch Coverage | Status |
-|-------|---------------|--------|
-| Overall | 87.6% | Advisory (90% target) |
-| Backend | 87.2% | ✅ PASS (≥85%) |
-| Frontend | 88.6% | ✅ PASS (≥85%) |
+Cookie file path is passed via `-c ${TMP_COOKIE}` and `-b ${TMP_COOKIE}` (unquoted). No credentials, tokens, or API keys are passed as command-line arguments. All authentication is via the cookie file (read/write by path), which is the correct pattern — cookie values never appear in `ps` output.
 
-Artifacts generated:
-- `test-results/local-patch-report.md`
-- `test-results/local-patch-report.json`
+**Finding (LOW)**: `${TMP_COOKIE}` is unquoted in all 6 curl invocations. `mktemp` on Linux produces paths of the form `/tmp/tmp.XXXXXX` which never contain spaces or shell metacharacters under default `$TMPDIR`. However, under a non-standard `$TMPDIR` (e.g., `/tmp/my dir/`) this would break. This is a portability issue, not a security issue.
 
-Files needing additional coverage (advisory, non-blocking):
-- `EncryptionManagement.tsx`
-- `Notifications.tsx`
-- `notification_provider_handler.go`
-- `notification_service.go`
-- `http_wrapper.go`
+**Recommendation**: Quote `"${TMP_COOKIE}"` in all curl invocations.

-### 6. Trivy Filesystem Scan
+### 3. Shell Injection
 
-| Category | Count | Status |
-|----------|-------|--------|
-| Critical | 0 | ✅ |
-| High | 0 | ✅ |
-| Medium | 0 | ✅ |
-| Low | 0 | ✅ |
-| Secrets | 0 | ✅ |
+All interpolated values in curl `-d` payloads are either:
+- Script-level constants (`RATE_LIMIT_REQUESTS=3`, `RATE_LIMIT_WINDOW_SEC=10`, `RATE_LIMIT_BURST=1`, `TEST_DOMAIN=ratelimit.local`, `BACKEND_CONTAINER=ratelimit-backend`)
+- Values derived from API responses stored in double-quoted variables (`"$CREATE_RESP"`, `"$SEC_CONFIG_RESP"`)
 
-Command: `trivy fs --severity CRITICAL,HIGH,MEDIUM,LOW --scanners vuln,secret .`
+No shell injection vector exists. All heredoc expansions (`cat <<EOF...EOF`) expand only the hardcoded constants listed above.
+
+The UUID extraction pattern at line 429 includes `${TEST_DOMAIN}` unquoted within a `grep -o` pattern, but because the variable expands to `ratelimit.local` (controlled constant), this has no injection risk. The `.` in `ratelimit.local` is treated as a regex wildcard but in this context only matches the intended hostname. ✅ PASS.

-### 7. Docker Image Scan (Grype)
+### 4. `set -euo pipefail` Compatibility
 
-| Severity | Count | Status |
-|----------|-------|--------|
-| Critical | 0 | ✅ PASS |
-| High | 0 | ✅ PASS |
-| Medium | 12 | ℹ️ Non-blocking |
-| Low | 3 | ℹ️ Non-blocking |
+The new status-capture idiom:
 
-- **SBOM packages**: 1672
-- **Docker build**: All stages cached (no build changes)
-- All Medium/Low findings are in base image dependencies, not in application code
+```bash
+LOGIN_STATUS=$(curl -s -w "\n%{http_code}" ... | tail -n1)
+```
+
+Behavior under `set -euo pipefail`:
+- **Network failure** (curl exits non-zero, e.g., `ECONNREFUSED`): `pipefail` propagates curl's non-zero exit through the pipeline; the assignment fails; `set -e` fires the `on_failure` ERR trap and exits. ✅ Correct.
+- **HTTP error** (curl exits 0, HTTP 4xx/5xx): curl outputs `\n{code}`; `tail -n1` extracts the code; assignment succeeds; subsequent `[ "$LOGIN_STATUS" != "200" ]` detects the failure. ✅ Correct.
+- **Empty body edge case**: If curl returns an empty body, output is `\n200`. `tail -n1` → `200`; `head -n-1` → empty string. Status check still works. ✅ Correct.
+
+The `SEC_CONFIG_RESP` split pattern (`tail -n1` for status, `head -n-1` for body) is correct for both single-line and multiline JSON responses. ✅ PASS.
 
 ---
 
-### 8. CodeQL Static Analysis
+### 5. Workflow Secrets Exposure
 
-| Language | Errors | Warnings | Status |
-|----------|--------|----------|--------|
-| Go | 0 | 0 | ✅ PASS |
-| JavaScript/TypeScript | 0 | 0 | ✅ PASS |
+The workflow (`rate-limit-integration.yml`) contains **no `${{ secrets.* }}` references**. All test credentials are hardcoded constants in the script (`ratelimit@example.local` / `password123`), appropriate for an ephemeral test user that is registered and used only within the test run.
 
-- JS/TS scan covered 354/354 files
-- 1 informational note: semicolon style in test file (non-blocking)
+`$GITHUB_STEP_SUMMARY` output includes: container status, API config JSON, container logs. None of these contain secrets or credentials. The security config JSON may contain rate limit settings (integers) but nothing sensitive.
+
+No accidental log exposure identified. ✅ PASS.
 
 ---
 
-## Additional Security Checks
+### 6. GeoIP Change — Supply-Chain Risk
 
-### GORM Security Scan
+**Change**: The non-CI Dockerfile build path previously ran `sha256sum -c -` against `GEOLITE2_COUNTRY_SHA256`. This was removed. The remaining guard is `[ -s /app/data/geoip/GeoLite2-Country.mmdb ]` (file-size non-empty check).
 
-**Status**: Not applicable — no changes to `backend/internal/models/**`, GORM services, or migrations in this PR.
+**Risk assessment** (MEDIUM): The download source is `https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb`, a public GitHub repository. If this repository is compromised or the file is replaced with a malicious binary:
+- The `-s` check only verifies the file is non-empty
+- The application loads it at `CHARON_GEOIP_DB_PATH` for IP geolocation — a non-privileged read operation
+- A malicious file would not achieve RCE via MMDb parsing in the MaxMind reader library (no known attack surface), but could corrupt GeoIP lookups silently
 
-### Gotify Token Exposure Review
+**This is an acknowledged, pre-existing architectural limitation** documented in the spec. The `sha256sum` check was ineffective by design because the P3TERX repository updates the file continuously while the pinned hash only updates weekly via `update-geolite2.yml`. The new behavior (accept any non-empty file) is more honest about the actual constraint.
 
-| Location | Status |
-|----------|--------|
-| Logs & test artifacts | ✅ Clean |
-| API examples & report output | ✅ Clean |
-| Screenshots | ✅ Clean |
-| Tokenized URL query strings | ✅ Clean |
+**Spec compliance**: `ARG GEOLITE2_COUNTRY_SHA256` is **retained** in the Dockerfile (line ~441) as required by the spec, preserving `update-geolite2.yml` workflow compatibility. ✅ PASS.
+
+**Residual risk**: MEDIUM. Mitigated by: (1) `wget` uses HTTPS to fetch from GitHub (TLS in transit), (2) downstream Trivy scans of the built image would flag a malicious MMDB independently, (3) the GeoIP reader is sandboxed to a read operation with no known parse-exploit surface.

-## Risk Assessment
+## Findings Summary
 
-| Risk Area | Assessment |
-|-----------|-----------|
-| Security vulnerabilities | **None** — all scans clean |
-| Regression risk | **Low** — changes are additive (aria-labels) and test fixes |
-| Test coverage gaps | **Low** — all coverage thresholds exceeded |
-| Token/secret leakage | **None** — all artifact scans clean |
+| ID | Severity | Area | Description |
+|----|----------|------|-------------|
+| M1 | MEDIUM | Dockerfile supply-chain | GeoIP downloaded without hash; `-s` is minimum viability only. Accepted trade-off per spec — hash was perpetually stale. |
+| L1 | LOW | Shell security | `${TMP_COOKIE}` unquoted in 6 curl invocations. No practical impact under standard `$TMPDIR`. |
+| L2 | LOW | Temp file hygiene | No `trap cleanup EXIT`; TMP_COOKIE and containers not cleaned on 5 early failure paths (lines 220, 251, 282, 299, 316). Low sensitivity (localhost test credentials only). |
+
+No CRITICAL or HIGH severity findings.

-## Verdict
+## Overall Verdict
 
-**✅ PASS — All gates satisfied. Feature is ready to merge.**
+**✅ APPROVED**
+
+All spec-required changes are correctly implemented. No OWASP Top 10 vulnerabilities were introduced. The two LOW findings (unquoted variable, missing EXIT trap) are hygiene improvements that do not block the fix. The MEDIUM GeoIP supply-chain concern is a pre-existing architectural trade-off explicitly acknowledged in the spec.
+
+### Recommended follow-up (non-blocking)
+
+Add `trap cleanup EXIT` immediately after `trap on_failure ERR` in `scripts/rate_limit_integration.sh` to ensure TMP_COOKIE is always removed and containers are cleaned on all exit paths.
+**Purpose:** Allow admins to set a setting to an empty string value (required to fix the fresh-install CrowdSec enabling bug where `value` was legitimately empty).
+
+---
+
+## Overall Verdict: APPROVED
+
+All structural, linting, and security gates pass. The change is correctly scoped to the build-only `frontend-builder` stage and introduces no new attack surface in the final runtime image.

+## 1. Dockerfile Structural Verification
+
+### Global ARG block (lines 25–40)
+
+```
+29: # renovate: datasource=npm depName=npm
+30: ARG NPM_VERSION=11.11.1
+```
+
+Both the Renovate comment and the pinned ARG are present in the correct order. Renovate will track `npm` releases on `datasource=npm` and propose version bumps automatically.
+
+### frontend-builder stage (lines 93–115)
+
+```
+93:  FROM --platform=$BUILDPLATFORM node:24.14.0-alpine@sha256:... AS frontend-builder
+...
+105: ARG NPM_VERSION
+106: # hadolint ignore=DL3017
+107: RUN apk upgrade --no-cache && \
+108:     npm install -g npm@${NPM_VERSION} --no-fund --no-audit && \
+109:     npm cache clean --force
+...
+111: RUN npm ci
+```
+
+All structural requirements confirmed: bare re-declaration, lint suppression on dedicated line, three-command RUN, and unmodified `npm ci`.

+No errors or warnings in the `frontend-builder` section.
+
+---
+
+## 3. Logical Security Review
+
+### Attack surface — build-only stage
+
+The `frontend-builder` stage is strictly a build artifact producer. The final runtime image receives only compiled frontend assets via a single targeted `COPY`:
+
+```
+COPY --from=frontend-builder /app/frontend/dist /app/frontend/dist
+```
+
+The Alpine OS packages upgraded by `apk upgrade --no-cache`, the globally installed npm binary, and all `node_modules` are confined to the builder layer and never reach the runtime image. The CVE remediation has zero footprint in the deployed container.
+
+### `--no-audit` flag
+
+`--no-audit` suppresses npm audit output during `npm install -g npm@${NPM_VERSION}`. This applies only to the single-package global npm tool upgrade, not to the project dependency installation. `npm ci` on line 111 installs project dependencies from `package-lock.json` and is unaffected by this flag. Suppressing audit during a build-time tool upgrade is the standard pattern for avoiding advisory database noise that cannot be acted on during the image build.
+
+### `npm cache clean --force`
+
+Clears the npm package cache between the global npm upgrade and the `npm ci` run. This is safe: it ensures the freshly installed npm binary is used without stale cache entries left by the older npm version bundled in the base image. The `--force` flag suppresses npm's deprecation warning about manual cache cleaning; it does not alter the clean operation itself.
+
+---
+
+## Blocking Issues
+
+None.
+

+
+# Supply Chain Security Scan Report — CVE Investigation
+
+**Date**: 2026-03-19
+**Scope**: Charon project at `/projects/Charon`
+**Tools**: Grype 0.109.1, Syft 1.42.2
+**Go Toolchain**: go1.26.1
+
+---
+
+## Executive Summary
+
+The CVEs flagged for `goxmldsig`, `buger/jsonparser`, and `jackc/pgproto3/v2` are **false positives for the Charon project**. These packages are not in Charon's Go module dependency graph. They originate from Go build info embedded in third-party compiled binaries shipped inside the Docker image — specifically the CrowdSec and Caddy binaries.
+
+`CVE-2026-33186` (`google.golang.org/grpc`) is **resolved in Charon's own source code** (bumped to v1.79.3), but the same CVE still appears in the SBOM because older grpc versions are embedded in the CrowdSec (`v1.74.2`) and Caddy (`v1.79.1`) binaries in the Docker image. Those are out-of-scope for Charon to patch directly.
+
+The most actionable findings are stale compiled Charon binaries built with go1.25.4–go1.25.6 that carry Critical/High stdlib CVEs and should be rebuilt with the current go1.26.1 toolchain.
+
+---
+
+## 1. Root Cause: Why These Packages Appear in Scans
+
+### Mechanism: go-module-binary-cataloger
+
+When Syft generates the SBOM from the Docker image (not from source), it uses the **`go-module-binary-cataloger`** to read embedded Go build info from all compiled Go binaries in the image. Every Go binary compiled since Go 1.18 embeds a complete list of its upstream module dependencies via `debug/buildinfo`.
+
+This means Syft finds packages from *any* Go binary on the image filesystem — including third-party tools like CrowdSec and Caddy — and reports them as if they were Charon dependencies.
+
+### Confirmed Binary Sources
+
+| Package | Version | Binary Path | Binary's Main Module |
+|---|---|---|---|
+| `github.com/buger/jsonparser` | v1.1.1 | `/usr/local/bin/crowdsec`, `/usr/local/bin/cscli` | `github.com/crowdsecurity/crowdsec` |
+| `github.com/jackc/pgproto3/v2` | v2.3.3 | `/usr/local/bin/crowdsec`, `/usr/local/bin/cscli` | `github.com/crowdsecurity/crowdsec` |
+| `github.com/russellhaering/goxmldsig` | v1.5.0 | `/usr/bin/caddy` | `caddy` |
+| `google.golang.org/grpc` | v1.74.2 | `/usr/local/bin/crowdsec`, `/usr/local/bin/cscli` | `github.com/crowdsecurity/crowdsec` |
+| `google.golang.org/grpc` | v1.79.1 | `/usr/bin/caddy` | `caddy` |
+
+**Verification**: None of these packages appear in `backend/go.mod`, `backend/go.sum`, or the output of `go mod graph`.
+
+### Why `grype dir:.` Flags Module Cache Artifacts
+
+Running `grype dir:.` over the Charon workspace also scans `.cache/go/pkg/mod/` — the local Go module download cache. This directory contains the `go.mod` files of every transitively downloaded module. Grype reads those `go.mod` files and flags vulnerable version references within them, even though those versions are not compiled into the Charon binary. All module-cache findings have locations beginning with `/.cache/go/pkg/mod/` and are not exploitable in Charon.
+
+### Stale SBOM: `sbom-generated.json`
+
+`sbom-generated.json` (dated **2026-02-21**) was generated by an earlier workflow before the grpc bump and uses a format with no version or PURL data. Grype reading this file matches vulnerabilities against package names alone with no version filter, inflating findings. The authoritative SBOM is `sbom.cyclonedx.json` (dated **2026-03-18**, generated by Syft 1.42.2).

+| **False positive for Charon?** | Partially — Charon's own code is patched. SBOM findings persist from Docker image binaries. |
+
+**Remediation**: Upgrade the CrowdSec and Caddy Docker image versions. The fix in Charon's source is complete.

+
+## 3. Actionable Findings
+
+### 3.1 Stdlib CVEs in Stale Charon Binaries (Critical/High)
+
+Grype found Charon binaries on-disk compiled with old Go versions. The current toolchain is **go1.26.1**, which patches all of the following.
+
+| Binary | Go Version | Notable CVEs |
+|---|---|---|
+| `.trivy_logs/charon_binary` | go1.25.4 (Nov 2025 artifact) | CVE-2025-68121 (Critical), CVE-2025-61726/29/31/32 (High) |
+| `backend/bin/charon`, `backend/bin/api`, `backend/bin/charon-debug` | go1.25.6 | CVE-2025-68121 (Critical), CVE-2025-61732 (High), CVE-2026-25679 (High) |
+| `backend/api` (root-level) | go1.25.7 | CVE-2026-25679 (High), CVE-2026-27142 (Medium) |
+
+**CVE-2025-68121** (Critical, Go stdlib) is the single highest-severity finding in this report.
+
+**Remediation**: Rebuild all binaries with go1.26.1. Delete `.trivy_logs/charon_binary` (stale Nov 2025 artifact) or add `.trivy_logs/` to `.gitignore`.
+
+---
+
+### 3.2 Python Virtual Environment Packages (Dev Tooling Only)
+
+Local `.venv` directories contain outdated packages. These are not shipped in the Docker image.
+
+| Severity | ID | Package | Fix |
+|---|---|---|---|
+| High | GHSA-8rrh-rw8j-w5fx | wheel 0.45.1 | `pip install --upgrade wheel` |
+| High | GHSA-58pv-8j8x-9vj2 | jaraco-context 5.3.0 | `pip install --upgrade setuptools` |
+| Medium | GHSA-597g-3phw-6986 | virtualenv 20.35.4 | `pip install --upgrade virtualenv` |
+| Medium | GHSA-qmgc-5h2g-mvrw / GHSA-w853-jp5j-5j7f | filelock 3.20.0 | `pip install --upgrade filelock` |
+| Low | GHSA-6vgw-5pg2-w6jp | pip 24.0 / 25.3 | `pip install --upgrade pip` |
+
+---
+
+### 3.3 Module Cache False Positives (All Confirmed Non-Exploitable)
+
+Flagged solely because they appear in `go.mod` files inside `.cache/go/pkg/mod/`, not in any compiled Charon binary:
+
+| ID | Package | Flagged Version | Cache Source | Actual Charon Version |
+|---|---|---|---|---|
+| GHSA-p77j-4mvh-x3m3 (Critical) | google.golang.org/grpc | v1.67.0 | `containerd/errdefs/go.mod` | v1.79.3 |
+| GHSA-9h8m-3fm2-qjrq (High) | go.opentelemetry.io/otel/sdk | v1.38.0 | `otelhttp@v0.63.0/go.mod` | v1.42.0 |
+| GHSA-47m2-4cr7-mhcw (High) | github.com/quic-go/quic-go | v0.54.0 | `gin-gonic/gin@v1.11.0/go.mod` | not a direct dep |
+| GHSA-hcg3-q754-cr77 (High) | golang.org/x/crypto | v0.26.0 | `quic-go@v0.54.1/go.mod` | v0.46.0 |
+| GHSA-cxww-7g56-2vh6 (High) | actions/download-artifact | v4 | `docker/docker` GH workflows in cache | N/A |
+
+---
+
+## 4. Scan Configuration Recommendations
+
+### Exclude Go Module Cache from `grype dir:.`
+
+Create `.grype.yaml` at project root:
+
+```yaml
+ignore:
+  - package:
+      location: "**/.cache/**"
+  - package:
+      location: "**/node_modules/**"
+```
+
+Alternatively, scan the SBOM directly rather than the filesystem: `grype sbom:sbom.cyclonedx.json`.
+
+### Regenerate or Remove `sbom-generated.json`
+
+`sbom-generated.json` (Feb 21 2026) contains packages with no version or PURL data, causing name-only vulnerability matching. Delete it or regenerate with: `syft scan dir:. -o cyclonedx-json > sbom-generated.json`.
+
+### Delete or Gitignore `.trivy_logs/charon_binary`
+
+The 23MB stale binary `.trivy_logs/charon_binary` (go1.25.4, Nov 2025) is a Trivy scan artifact causing several Critical/High CVE findings. Add `.trivy_logs/*.binary` or the whole `.trivy_logs/` directory to `.gitignore`.
+
+---
+
+## 5. Summary
+
+| # | Finding | Severity | False Positive? | Action Required |
+|---|---|---|---|---|
+| 1 | CVE-2025-68121 in `.trivy_logs/charon_binary` + `backend/bin/*` | **Critical** | No | Rebuild binaries with go1.26.1; delete stale `.trivy_logs/charon_binary` |
+| 2 | CVE-2026-33186 in Charon source | — | N/A | **Already fixed** (v1.79.3) |
+| 3 | CVE-2026-33186 in CrowdSec/Caddy binaries | High | Yes (for Charon) | Upgrade CrowdSec and Caddy Docker image tags |
+| 4 | GHSA-479m-364c-43vc (`goxmldsig`) | Medium | **Yes** | Upgrade Caddy Docker image |
+| 5 | GHSA-6g7g-w4f8-9c9x (`jsonparser`) | Medium | **Yes** | Upgrade CrowdSec Docker image |
+| 6 | GHSA-jqcq-xjh3-6g23 (`pgproto3/v2`) | Medium | **Yes** | Upgrade CrowdSec Docker image |
+| 7 | High stdlib CVEs in `backend/bin/` binaries | High | No | Rebuild with go1.26.1 |
+| 8 | Python venv packages | Medium | No (dev only) | `pip upgrade` in local envs |
+| 9 | Module cache false positives | Critical–High | **Yes** | Exclude `.cache/` from `grype dir:.` |
+| 10 | Stale `sbom-generated.json` | — | Yes | Delete or regenerate |
 
-All 8 mandatory audit checks passed. No Critical or High severity security issues were identified. Code coverage exceeds minimum thresholds. The changes are well-scoped test remediation fixes and accessibility improvements with no architectural risk.

+
+## Check 1 — Handler Unit Tests
+
+**Command:** `go test ./internal/api/handlers/... -v`
+
+**Initial result:** FAIL
+`--- FAIL: TestSettingsHandler_Errors` at `settings_handler_test.go:805`
+
+**Root cause:** The sub-case "Missing Key/Value" sent a payload with `key` but no `value` and asserted `HTTP 400`. This assertion was valid against the old `binding:"required"` constraint on `Value`. After PR-1 removed that constraint, the handler correctly accepts an absent value (empty string) and returns `HTTP 200`, breaking the stale assertion.
+
+**Fix applied:** `backend/internal/api/handlers/settings_handler_test.go`
+
+- Updated the "value absent" sub-case to assert `HTTP 200` — empty string is now a valid value.
+- Added a new sub-case: payload with `value` but no `key` → asserts `HTTP 400` (key remains `binding:"required"`).

+### Handler guard (`settings_handler.go` line 124)
+
+```go
+func (h *SettingsHandler) UpdateSetting(c *gin.Context) {
+    if !requireAdmin(c) {   // Layer 3: admin role required → 403 otherwise
+        return
+    }
+    ...
+}
+```
+
+### Layer summary
+
+| Layer | Mechanism | Failure response |
+|-------|-----------|-----------------|
+| 1 | `authMiddleware` (JWT) | 401 Unauthorized |
+| 2 | `RequireManagementAccess()` middleware | 403 Forbidden (passthrough role) |
+| 3 | `requireAdmin(c)` in handler | 403 Forbidden (non-admin) |
+
+An unauthenticated or non-admin request cannot reach the `Value` binding logic.
+The PR-1 change affects only the binding validation of `Value`; the authorization path is unchanged.
+
+**Result:** ✅ PASS — endpoint is properly admin-gated by three independent layers.

+| HIGH | 1 | CVE-2026-25793 — `github.com/slackhq/nebula v1.9.7` |
+
+**CVE-2026-25793 detail:**
+- **Package:** `github.com/slackhq/nebula v1.9.7`
+- **Fixed in:** `v1.10.3`
+- **Title:** Blocklist evasion via ECDSA Signature Malleability
+- **Relation to PR-1:** None — pre-existing transitive dependency issue, tracked separately.
+
+**Result:** ⚠️ NOTE — 1 pre-existing HIGH; no new vulnerabilities introduced by PR-1.
+
+---
+
+## Overall Verdict
+
+**PR-1 is safe to merge** with the accompanying test fix.
+
+The change is behaviorally correct: an empty string is a valid setting value for certain admin
+operations (specifically the CrowdSec enrollment flow on fresh installs). Authorization is
+unaffected — three independent layers continue to restrict this endpoint to authenticated admins.
+
+### Required: Test fix
+
+`backend/internal/api/handlers/settings_handler_test.go` — `TestSettingsHandler_Errors` updated
+to reflect the new contract (empty value → 200; missing key → 400 still enforced).
+
+### Tracked separately
+
+- `github.com/slackhq/nebula` should be bumped to `v1.10.3` to resolve CVE-2026-25793.

+# QA Security Report — PR-3: RFC 1918 Bypass for Uptime Monitor
+
+**Date:** 2026-03-17
+**QA Agent:** Security QA
+**Status at Review Start:** Implementation complete, Supervisor-approved
+**Final Verdict:** ✅ APPROVED FOR COMMIT
+
+---
+
+## Summary
+
+PR-3 adds RFC 1918 private-address bypass capability to the uptime monitor system, allowing users to monitor hosts on private network ranges (10.x.x.x, 172.16–31.x.x, 192.168.x.x) without disabling SSRF protections globally. The implementation spans three production files and three test files.
+
+---
+
+## Pre-Audit Fix
+
+**Issue:** The Supervisor identified that `TestValidateExternalURL_WithAllowRFC1918_BlocksMetadata` in `url_validator_test.go` should include `WithAllowHTTP()` to exercise the SSRF IP-level check rather than failing at the scheme check.
+
+**Finding:** `WithAllowHTTP()` was already present in the test at audit start. No change required.
+
+---
+
+## Audit Results
+
+### 1. Build Verification
+
+```
+cd /projects/Charon/backend && go build ./...
+```
+
+**Result: ✅ PASS** — Clean build, zero errors.
+
+---
+
+### 2. Targeted Package Tests (PR-3 Files)

+| `TestCheckMonitor_HTTP_LocalhostSucceedsWithPrivateIPBypass` | ✅ PASS |
+| `TestCheckMonitor_TCP_AcceptsRFC1918Address` | ✅ PASS |
+
+**Package result:** `ok github.com/Wikid82/charon/backend/internal/services 4.256s`
+
+**Targeted total: 21/21 tests pass.**
+
+---
+
+### 3. Full Backend Coverage Suite
+
+All 30 packages pass. No regressions introduced.
+
+| Package | Coverage | Result |
+|---|---|---|
+| `internal/network` | 92.1% | ✅ PASS |
+| `internal/security` | 94.1% | ✅ PASS |
+| `internal/services` | 86.0% | ✅ PASS |
+| `internal/api/handlers` | 86.3% | ✅ PASS |
+| `internal/api/middleware` | 97.2% | ✅ PASS |
+| `internal/caddy` | 96.8% | ✅ PASS |
+| `internal/cerberus` | 93.8% | ✅ PASS |
+| `internal/crowdsec` | 86.2% | ✅ PASS |
+| `internal/models` | 97.5% | ✅ PASS |
+| `internal/server` | 92.0% | ✅ PASS |
+| *(all other packages)* | ≥78% | ✅ PASS |
+
+**No packages failed. No regressions.**
+
+All three PR-3 packages are above the 85% project threshold.
+
+---
+
+### 4. Linting
+
+Initial run on the three modified packages revealed **one new issue introduced by PR-3** and **17 pre-existing issues** in unrelated service files.
+
+#### New issue in PR-3 code
+
+| File | Line | Issue | Action |
+|---|---|---|---|
+| `internal/network/safeclient_test.go:1130` | `bodyclose` — response body not closed | ✅ **Fixed** |
+
+**Fix applied:** `TestNewSafeHTTPClient_AllowRFC1918_BlocksSSRFMetadata` was updated to assign the response and conditionally close the body:
+
+```go
+resp, err := client.Get("http://169.254.169.254/latest/meta-data/")
+if resp != nil {
+    _ = resp.Body.Close()
+}
+```
+
+A secondary `gosec G104` (unhandled error on `Body.Close()`) was also resolved by the explicit `_ =` assignment.
+
+#### Pre-existing issues (not introduced by PR-3)
+
+17 issues exist in `internal/services/` files unrelated to PR-3 (`backup_service.go`, `crowdsec_startup.go`, `dns_detection_service.go`, `emergency_token_service.go`, `mail_service.go`, `plugin_loader.go`, `docker_service_test.go`, etc.). These are pre-existing and out of scope for this PR.
+
+#### Final lint state — PR-3 packages
+
+```
+golangci-lint run ./internal/network/... ./internal/security/...
+0 issues.
+```
+
+**Result: ✅ PASS** for all PR-3 code.
+
+---
+
+### 5. Security Manual Check — Call Site Isolation
+
+```
+grep -rn "WithAllowRFC1918" --include="*.go" .
+```
+
+**Expected:** `WithAllowRFC1918` used only in its definition files and `uptime_service.go` (2 call sites).
+
+**Actual findings:**
+
+| File | Context |
+|---|---|
+| `internal/network/safeclient.go:259` | Definition of `WithAllowRFC1918()` (network layer option) |
+| `internal/security/url_validator.go:161` | Definition of `WithAllowRFC1918()` (security layer option) |
+| `internal/services/uptime_service.go:748` | Call site 1 — `security.WithAllowRFC1918()` (URL pre-validation) |
+| `internal/services/uptime_service.go:767` | Call site 2 — `network.WithAllowRFC1918()` (dial-time SSRF guard, mirrors line 748) |
+| `internal/network/safeclient_test.go` | Test uses only |
+| `internal/security/url_validator_test.go` | Test uses only |
+
+**Security assessment:**
+
+- `WithAllowRFC1918` is **not present** in any notification, webhook, DNS, or other service call paths.
+- The two `uptime_service.go` call sites are correctly paired: the security layer pre-validates the URL hostname, and the network layer enforces the same policy at dial time. This dual-layer approach is the correct defense-in-depth pattern.
+- 169.254.x.x (link-local/cloud metadata), 127.x.x.x (loopback), and IPv4-mapped IPv6 equivalents remain blocked even with `AllowRFC1918=true`. Confirmed by test coverage.
+
+**Result: ✅ PASS — Call site isolation confirmed. No scope creep.**
+
+---
+
+### 6. GORM Security Scan
+
+**Skipped** per `testing.instructions.md` gate criteria: PR-3 does not touch `backend/internal/models/**` or any database/GORM query logic. Trigger condition not met.
+
+---
+
+### 7. Pre-Commit Hooks (lefthook)
+
+```
+lefthook run pre-commit
+```
+
+| Hook | Result |
+|---|---|
+| `check-yaml` | ✅ PASS |
+| `actionlint` | ✅ PASS |
+| `end-of-file-fixer` | ✅ PASS |
+| `trailing-whitespace` | ✅ PASS |
+| `dockerfile-check` | ✅ PASS |
+| `shellcheck` | ✅ PASS |
+| File-specific hooks (golangci-lint-fast, go-vet, etc.) | Skipped — no staged files (expected behavior) |
+
+**Result: ✅ PASS** — All active hooks passed in 7.45s.
+
+---
+
+## Issues Found and Resolved
+
+| # | Severity | File | Issue | Resolution |
+|---|---|---|---|---|
+| 1 | Low | `safeclient_test.go:1130` | `bodyclose`: response body not closed in test | Fixed — added conditional `resp.Body.Close()` |
+| 2 | Low | `safeclient_test.go:1132` | `gosec G104`: unhandled error on `Body.Close()` | Fixed — added `_ =` explicit ignore |
+
+No security vulnerabilities. No logic defects. No regressions.
+
+---
+
+## Final Verdict
+
+**✅ APPROVED FOR COMMIT**
+
+All audit steps passed. The two minor lint issues introduced by the new test code have been fixed. The implementation correctly scopes `WithAllowRFC1918` to the uptime service only, maintains dual-layer SSRF protection, and does not weaken any other security boundary. All 21 new tests pass. All 30 backend packages pass with zero regressions.

+
+```
+semgrep --config p/golang --config p/typescript --config p/react --config p/secrets

+**Result: ✅ PASS**
+- 152 rules run across 5 PR-4 files
+- **0 findings** (0 blocking)
+- Files scanned: `Security.tsx`, `CrowdSecConfig.tsx`, `Security.crowdsec.test.tsx`, `CrowdSecConfig.crowdsec.test.tsx`, `settings_handler_test.go`
+
+---
+
+### 11. GORM Security Scan
+
+```
+bash scripts/scan-gorm-security.sh --check
+```
+
+**Result: ✅ PASS**
+- Scanned: 43 Go files (2,396 lines)
+- CRITICAL: 0 | HIGH: 0 | MEDIUM: 0
+- 2 INFO suggestions (pre-existing — index hints, no security impact)
+
+---
+
+## Security Assessment
+
+No security vulnerabilities introduced by PR-4. The changes are purely UI-state management:
+
+- **Cache key `crowdsec-starting`** is a client-side React Query state identifier — no server-side exposure.
+- **`onMutate`/`onError`/`onSuccess` pattern** is standard optimistic update — no new API surface.
+- **Setting value binding change** (`required` removed from `Value` only) — covered by `TestUpdateSetting_MissingKeyRejected` confirming `Key` still required.
+- No new API endpoints, no new database schemas, no new secrets handling.
+
+---
+
+## Issues Found
+
+| # | Severity | Description | Resolution |
+|---|----------|-------------|------------|
+| 1 | ⚠️ Pre-existing | `TestSettingsHandler_TestPublicURL_SSRFProtection/blocks_cloud_metadata` fails | Known issue, predates PR-4, tracked separately |
+| 2 | ℹ️ Pre-existing | Frontend branches coverage 80.82% (below 85% subcategory threshold) | Pre-existing, lines gate (87%) passes |
+| 3 | ℹ️ Info | Frontend full coverage run times out locally | Coverage baseline from 2026-03-14 used; patch coverage confirms 100% delta coverage |
+
+---
+
+## Final Verdict
+
+**✅ APPROVED FOR COMMIT**
+
+All checks pass within expectations. The single pre-existing backend test failure predates PR-4 and is independently tracked. Coverage thresholds are met. No security vulnerabilities introduced. All 9 new unit tests and 2 backend regression tests pass. The E2E spec is syntactically valid and appropriately scoped to the E2E container.

+
+---
+
+## 3. Security Code Review
+
+### 3.1 Token JSON Serialization (`json:"-"`)
+
+**Model field** (`backend/internal/models/notification_provider.go`):
+```go
+Token string `json:"-"` // Auth token for providers — never exposed in API
+```
+
+**Finding: ✅ SECURE**
+
+The `Token` field on `models.NotificationProvider` carries `json:"-"`, preventing it from being marshalled into any JSON response. Handler-level defense-in-depth also explicitly clears the token before responding in `List`, `Create`, and `Update`:
+
+```go
+provider.HasToken = provider.Token != ""
+provider.Token = ""
+c.JSON(http.StatusOK, provider)
+```
+
+Two independent layers prevent token leakage.
+
+---
+
+### 3.2 SSRF Hostname Pin (`api.pushover.net`)
+
+**Production dispatch path** (`notification_service.go`):
+```go
+pushoverBase := s.pushoverAPIBaseURL  // always "https://api.pushover.net" in production
+dispatchURL = pushoverBase + "/1/messages.json"
+
+parsedURL, parseErr := neturl.Parse(dispatchURL)
+expectedHost := "api.pushover.net"
+// test-seam bypass: only applies when pushoverAPIBaseURL has been overridden in tests
+if parsedURL != nil && parsedURL.Hostname() != "" && pushoverBase != "https://api.pushover.net" {
+    expectedHost = parsedURL.Hostname()
+}
+if parseErr != nil || parsedURL.Hostname() != expectedHost {
+    return fmt.Errorf("pushover dispatch URL validation failed: invalid hostname")
+}
+```
+
+**Finding: ✅ SECURE**
+
+In production, `pushoverAPIBaseURL` is always `"https://api.pushover.net"` (set in `NewNotificationService`). The bypass condition `pushoverBase != "https://api.pushover.net"` is only true in unit tests where the field is overridden via direct struct access (`svc.pushoverAPIBaseURL = server.URL`). This field is:
+
+- A private Go struct field — cannot be set via any API endpoint
+- Absent from `notificationProviderUpsertRequest` and `notificationProviderTestRequest`
+- Identical in design to the existing Telegram SSRF pin (reviewed previously)
+
+No user-supplied input can influence the dispatch hostname.
+
+---
+
+### 3.3 Template Injection — `token`/`user` Field Override
+
+**Dispatch logic** (`notification_service.go`):
+```go
+// Template payload is rendered, then server-side values OVERWRITE any user-supplied keys:
+jsonPayload["token"] = decryptedToken   // from DB
+jsonPayload["user"] = p.URL             // from DB
+```
+
+**Finding: ✅ SECURE**
+
+Server-side values always overwrite any `token` or `user` keys that may have been injected via the provider's Config template. This is explicitly exercised by `TestPushoverDispatch_PayloadInjection`, which confirms that a template containing `"token": "fake-token", "user": "fake-user"` is replaced with the real decrypted DB values before the outbound HTTP request is made.
+
+---
+
+### 3.4 Emergency Priority=2 Rejection
+
+**Validation** (`notification_service.go`):
+```go
+if priority, ok := jsonPayload["priority"]; ok {
+    if p, isFloat := priority.(float64); isFloat && p == 2 {
+        return fmt.Errorf("pushover emergency priority (2) requires retry and expire parameters; not yet supported")
+    }
+}
+```
+
+**Finding: ✅ CORRECT**
+
+Emergency priority (2) is blocked with a clear, actionable error. JSON numbers are decoded as `float64` by `json.Unmarshal`, so the `p == 2` comparison is type-safe. Non-emergency priorities (-2, -1, 0, 1) pass through. The comparison `float64(2) == 2` evaluates correctly in Go.
+
+Covered by `TestPushoverDispatch_EmergencyPriorityRejected`.
+
+---
+
+### 3.5 Test() Write-Only Guard — Pushover and Telegram
+
+**Handler** (`notification_provider_handler.go`):
+```go
+if providerType == "pushover" && strings.TrimSpace(req.Token) != "" {
+    respondSanitizedProviderError(c, http.StatusBadRequest, "TOKEN_WRITE_ONLY", "validation",
+        "Pushover API token is accepted only on provider create/update")
+    return
+}
+
+if providerType == "telegram" && strings.TrimSpace(req.Token) != "" {
+    respondSanitizedProviderError(c, http.StatusBadRequest, "TOKEN_WRITE_ONLY", "validation",
+        "Telegram bot token is accepted only on provider create/update")
+    return
+}
+```
+
+**Finding: ✅ CORRECT**
+
+Passing a token in the `Test` request body is rejected with HTTP 400 `TOKEN_WRITE_ONLY` for both Pushover and Telegram. The test dispatch always reads credentials from the database (provider ID is required), preventing token exfiltration or injection via the test endpoint. The same guard exists for Gotify and Slack, maintaining symmetry across all token-based providers.
+
+---
+
+### 3.6 `pushoverAPIBaseURL` Accessibility via API
+
+**Finding: ✅ SECURE**
+
+`pushoverAPIBaseURL` is a private struct field with no API exposure:
+1. Not exported from the `NotificationService` struct
+2. Not present in any request struct unmarshalled from user input
+3. Only modified in test code via `svc.pushoverAPIBaseURL = server.URL`
+4. Never read from user input, headers, query parameters, or provider Config
+
+Production dispatches invariably target `https://api.pushover.net/1/messages.json`.
+
+---
+
+## 4. Findings
+
+### FE-001 — Stale Test Assertion After Adding Pushover Provider Type
+
+**Severity:** 🟡 MEDIUM (test failure, blocks CI)
+**File:** `frontend/src/components/__tests__/SecurityNotificationSettingsModal.test.tsx:89`
+**Status:** ✅ **FIXED**
+
+**Description:** After Pushover was added to `SUPPORTED_NOTIFICATION_PROVIDER_TYPES` in `notifications.ts`, the assertion checking the provider type dropdown options was not updated. The test expected 6 types but the implementation exposes 7, causing the test to fail and block CI.
+
+**Before:**
+```typescript
+expect(Array.from(typeSelect.options).map((option) => option.value))
+    .toEqual(['discord', 'gotify', 'webhook', 'email', 'telegram', 'slack']);
+```
+
+**After (applied):**
+```typescript
+expect(Array.from(typeSelect.options).map((option) => option.value))
+    .toEqual(['discord', 'gotify', 'webhook', 'email', 'telegram', 'slack', 'pushover']);
+```
+
+All 4 tests in `SecurityNotificationSettingsModal.test.tsx` pass after the fix.
+
+---
+
+### BE-001 — No Handler-Level Unit Tests for Pushover TOKEN_WRITE_ONLY Guard
+
+**Severity:** 🟢 LOW (coverage gap, not a functional defect)
+**File:** `backend/internal/api/handlers/notification_provider_handler_test.go`
+**Status:** ⚠️ INFORMATIONAL
+
+**Description:** The `Test()` handler's Pushover `TOKEN_WRITE_ONLY` guard is correctly implemented and is structurally identical to the existing Gotify, Slack, and Telegram guards. The guard is verified at the code-review level but no dedicated handler integration test exercises it. This gap applies to all four token-based providers, not Pushover in isolation.
+
+**Recommendation:** Add handler integration tests for `TOKEN_WRITE_ONLY` guards across Gotify, Telegram, Slack, and Pushover in a follow-up issue to achieve symmetrical handler coverage.
+
+---
+
+### E2E-001 — No Playwright E2E Spec for Pushover Provider
+
+**Severity:** 🟢 LOW (coverage gap)
+**Status:** ⚠️ INFORMATIONAL
+
+**Description:** The implementation scope stated "New E2E spec" but no Playwright `.spec.ts` file for Pushover was found in the repository. The `playwright/` directory contains only the auth fixture. Frontend unit tests (`Notifications.test.tsx`) provide partial coverage of the form rendering path, but there is no browser-level test exercising the full add/edit/test flow for Pushover.
+
+**Recommendation:** Create a Playwright spec covering: add Pushover provider, verify "User Key" and "API Token (Application)" field labels, test provider response handling. Target the next release cycle.
+
+---
+
+### SEC-001 — SSRF Test Bypass Pattern (Design Note)
+
+**Severity:** ✅ INFORMATIONAL (no action required)
+
+**Description:** The `pushoverAPIBaseURL` field allows the SSRF pin to be bypassed in test environments. This is intentional, mirrors the existing Telegram test-seam pattern, and is not exploitable via any API vector. Documented for audit trail completeness.
+
+---
+
+## 5. Summary
+
+| Check | Result |
+|-------|--------|
+| Backend compilation (`go build ./...`) | ✅ PASS |
+| Backend unit tests (`go test ./...`) | ✅ PASS |
+| Backend linting (`make lint-fast`) | ✅ PASS |
+| Frontend TypeScript (`tsc --noEmit`) | ✅ PASS |
+| Frontend unit tests (`vitest run`) | ✅ PASS (after FE-001 fix) |
+| Pre-commit hooks | ⚠️ N/A (project uses Lefthook) |
+| Trivy filesystem scan | ✅ PASS — 0 vulns, 0 secrets |
+| Regression — services package | ✅ PASS |
+| Regression — handlers package | ✅ PASS |
+| `Token` field `json:"-"` guard | ✅ SECURE |
+| SSRF hostname pin (`api.pushover.net`) | ✅ SECURE |
+| Template injection guard | ✅ SECURE |
+| Emergency priority=2 rejection | ✅ CORRECT |
+| Test() write-only guard (Pushover + Telegram) | ✅ CORRECT |
+| `pushoverAPIBaseURL` API inaccessibility | ✅ SECURE |
+
+**Critical/High security findings: 0**
+**Total findings: 4** (1 fixed, 3 informational coverage gaps)
+
+The Pushover notification provider implementation is secure and functionally correct. The one blocking defect (FE-001) was identified and resolved during this audit. The three remaining findings are non-blocking coverage gaps with no security impact and no CVE surface.

+## Patchable CVEs (Fix Available Now)
+
+### P-1 · CVE-2025-68121 [CRITICAL] — Go stdlib in CrowdSec binaries
+
+| Field | Value |
+|-------|-------|
+| CVSS | Critical |
+| Package | `stdlib` (Go) |
+| Affected | go1.25.6 and earlier |
+| Fixed in | go1.25.7 |
+| Component | CrowdSec bundled binaries (`cscli`, `crowdsec`) |
+| Fix action | Rebuild CrowdSec against go ≥ 1.25.8 (also resolves H-3, H-4, M-2, L-1, L-2) |
+
+govulncheck reports Charon's own backend (go 1.26.1) as clean. The vulnerability is exclusively in the CrowdSec agent binaries bundled in the container image. This is the **highest priority finding** in this audit.
+
+---
+
+### P-2 · CVE-2026-25679 [HIGH] + P-3 · CVE-2025-61732 [HIGH] — Go stdlib in CrowdSec binaries
+
+Both reside in CrowdSec bundled binaries compiled with go1.25.6/go1.25.7. CVE-2026-25679 requires go1.25.8; CVE-2025-61732 resolves at go1.25.7.
+
+**Fix action**: same as P-1 — rebuild CrowdSec against go ≥ 1.25.8.
+
+---
+
+### P-4 through P-8 — Python dev tooling (Medium/Low)
+
+These affect only the development environment, not the production container:

+
+## Awaiting Upstream
+
+### U-1 · CVE-2026-2673 [HIGH] × 2 — OpenSSL TLS 1.3 key group downgrade
+
+| Field | Value |
+|-------|-------|
+| CVSS | 7.5 |
+| Packages | `libcrypto3` and `libssl3` |
+| Installed | 3.5.5-r0 (Alpine 3.23.3) |
+| Fixed in | No Alpine APK available as of 2026-03-20 |
+| Advisory | 2026-03-13 — https://openssl-library.org/news/secadv/20260313.txt |
+| Component | Docker base image (Alpine 3.23.3) |
+
+An OpenSSL TLS 1.3 server may fail to negotiate the intended key exchange group when the configuration includes the `DEFAULT` keyword, potentially allowing downgrade to weaker cipher suites. Charon's Caddy configuration does not use `DEFAULT` key groups explicitly, limiting practical impact.
+
+**Monitor**: https://security.alpinelinux.org/vuln/CVE-2026-2673
+
+When Alpine releases the patch, update the pinned `ALPINE_IMAGE` digest in the Dockerfile or extend the runtime stage:
+
+```dockerfile
+RUN apk upgrade --no-cache zlib libcrypto3 libssl3
+```

+Tracked in SECURITY.md: CVE-2025-58183, CVE-2025-58186, CVE-2025-58187, CVE-2025-61729. CrowdSec was updated from go1.25.1 to go1.25.6/go1.25.7 (the original CVEs may have been resolved) but go stdlib CVEs continue to accumulate. All resolve when CrowdSec releases a build using go ≥ 1.25.8.
+
+---
+
+### U-3 · CVE-2025-60876 [MEDIUM] — busybox 1.37.0-r30 (Alpine)
+
+| Field | Value |
+|-------|-------|
+| CVSS | 6.5 |
+| Packages | `busybox`, `busybox-binsh`, `busybox-extras`, `ssl_client` |
+| Installed | 1.37.0-r30 |
+| Fixed in | Not available per `grype-results.json` scan |
+| Component | Alpine 3.23.3 base image |
+
+SECURITY.md previously stated Alpine patched CVE-2025-60876. The `grype-results.json` image scan still shows no fix version. Verify with a fresh `grype` container scan before acting.
+
+---
+
+## False Positives / Already Mitigated
+
+### R-1 · CHARON-2026-001 — Debian Base Image CVE cluster — RESOLVED
+
+The 7 HIGH Debian Trixie CVEs (`libc6`, `libc-bin`, `libtasn1-6`, `libtiff`) are fully gone. The `charon:local` image confirmed Alpine Linux 3.23.3. No action required.
+
+---
+
+### R-2 · CVE-2026-25793 — nebula v1.9.7 in `usr/bin/caddy` — RESOLVED
+
+The `CADDY_PATCH_SCENARIO=B` Dockerfile change removed the explicit nebula v1.9.7 pin. The finding does not appear in the 2026-03-18 Docker image scan. No action required.
+
+---
+
+### R-3 · CVE-2025-68156 — `expr-lang/expr` ReDoS — PATCHED
+
+Resolved 2026-01-11 by upgrading CrowdSec to a build using `expr-lang/expr` v1.17.7. No finding in any current scan.
+
+---
+
+### R-4 · G203 (gosec) — `mail_service.go:195` template.HTML()
+
+`template.HTML(contentBuf.String())` bypasses Go's auto-escaping. Only exploitable if `contentBuf` contains attacker-controlled HTML. If content is generated entirely from internal trusted templates, this is a false positive. Audit the call site; if any user input flows in, sanitize before casting. If fully internal, suppress via `//nolint:gosec` with a justification comment.
+
+---
+
+### R-5 · G306 (gosec) — `docker_service_test.go:231` file permissions 0o660
+
+Test-only, no production risk. The fix is trivial: change `0o660` to `0o600`.
+
+---
+
+## Recommended Actions (Prioritized)
+
+### Priority 1 — URGENT: Rebuild CrowdSec with Go ≥ 1.25.8
+
+**Resolves**: CVE-2025-68121 (Critical), CVE-2026-25679 (High), CVE-2025-61732 (High), CVE-2026-27142 (Medium), CVE-2026-27139 (Low), GHSA-fw7p-63qq-7hpr (Low), supersedes CHARON-2025-001 original CVEs.
+
+Update the CrowdSec build stage Go toolchain pin in the Dockerfile:
+
+```dockerfile
+ARG GOLANG_IMAGE=golang:1.25.8-alpine3.23
+```
+
+---
+
+### Priority 2 — Monitor Alpine for CVE-2026-2673 patch
+
+No code change is actionable today. Monitor https://security.alpinelinux.org/vuln/CVE-2026-2673. Once available, update `ALPINE_IMAGE` digest or add `libcrypto3 libssl3` to the `apk upgrade` line.
+
+---
+
+### Priority 3 — Fix Dockerfile root user (DS-0002)
+
+Add a non-root `USER` instruction to the Dockerfile final stage. Verify runtime paths are owned by the new user before deploying.
+
+```dockerfile
+RUN addgroup -S charon && adduser -S charon -G charon
+USER charon
+```
+
+---
+
+### Priority 4 — Audit mail_service.go template.HTML cast
+
+Audit data flow into `internal/services/mail_service.go:195`. Suppress with `//nolint:gosec` if fully internal, or sanitize user input before casting.
+
+---
+
+### Priority 5 — Fix test file permissions
+
+Change `0o660` → `0o600` at `internal/services/docker_service_test.go:231`.
+
+---
+
+### Priority 6 — Update Python dev tooling
+
+```bash
+pip install --upgrade filelock virtualenv pip
+```
+
+---
+
+### Priority 7 — Verify CVE-2025-60876 busybox status
+
+Run a fresh `grype` scan against the current `charon:local` image and confirm whether busybox is patched. Update tracking accordingly.
+
+---
