+# Manual Test Tracking Plan - PR-2 Security Posture Closure
+
+## Scope
+PR-2 only.
+
+This plan tracks manual verification for:
+- Patch disposition decisions
+- Admin API assumptions and guardrails
+- Rollback checks
+
+Out of scope:
+- PR-1 compatibility closure tasks
+- PR-3 feature or UX expansion
+
+## Preconditions
+- [ ] Branch contains PR-2 documentation and configuration changes only.
+- [ ] Environment starts cleanly with default PR-2 settings.
+- [ ] Tester can run container start/restart and review startup logs.
+
+## Track A - Patch Disposition Validation
+
+### TC-PR2-001 Retained patches remain retained
+- [ ] Verify `expr` and `ipstore` patch decisions are documented as retained in the PR-2 security posture report.
+- [ ] Confirm no conflicting PR-2 docs state these patches are retired.
+- Expected result: retained/retained remains consistent across PR-2 closure docs.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+### TC-PR2-002 Nebula default retirement is clearly bounded
+- [ ] Verify PR-2 report states `nebula` retirement is by default scenario switch.
+- [ ] Verify rollback instruction is present and explicit.
+- Expected result: reviewer can identify default posture and rollback without ambiguity.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+## Track B - Admin API Assumption Checks
+
+### TC-PR2-003 Internal-only admin API assumption
+- [ ] Confirm PR-2 report states admin API is expected to be internal-only.
+- [ ] Confirm PR-2 QA report includes admin API validation/normalization posture.
+- Expected result: both reports communicate the same assumption.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+### TC-PR2-004 Invalid admin endpoint fails fast
+- [ ] Start with an intentionally invalid/non-allowlisted admin API URL.
+- [ ] Verify startup fails fast with clear configuration rejection behavior.
+- [ ] Restore valid URL and confirm startup succeeds.
+- Expected result: unsafe endpoint rejected; safe endpoint accepted.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+### TC-PR2-005 Port exposure assumption holds
+- [ ] Verify deployment defaults do not publish admin API port `2019`.
+- [ ] Confirm no PR-2 doc contradicts this default posture.
+- Expected result: admin API remains non-published by default.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+## Track C - Rollback Safety Checks
+
+### TC-PR2-006 Scenario rollback switch
+- [ ] Set `CADDY_PATCH_SCENARIO=A`.
+- [ ] Restart and verify the rollback path is accepted by the runtime.
+- [ ] Return to PR-2 default scenario and verify normal startup.
+- Expected result: rollback is deterministic and reversible.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+### TC-PR2-007 QA report rollback statement alignment
+- [ ] Confirm QA report and security posture report use the same rollback instruction.
+- [ ] Confirm both reports remain strictly PR-2 scoped.
+- Expected result: no conflicting rollback guidance; no PR-3 references.
+- Status: [ ] Not run [ ] Pass [ ] Fail
+- Notes:
+
+## Defect Log
+
+| ID | Test Case | Severity | Summary | Reproducible | Status |
+| --- | --- | --- | --- | --- | --- |
+| | | | | | |
+
+## Exit Criteria
+- [ ] All PR-2 test cases executed.
+- [ ] No unresolved critical defects.
+- [ ] Patch disposition, admin API assumptions, and rollback checks are all verified.
+- [ ] No PR-3 material introduced in this tracking plan.

+## Focused Plan: GitHub Actions `setup-go` Cache Warning (`go.sum` path)
+
+Date: 2026-02-23
+Status: Planned
+Scope: Warning-only fix for GitHub Actions cache restore message:
+`Restore cache failed: Dependencies file is not found in
+/home/runner/work/Charon/Charon. Supported file pattern: go.sum`.
+
+### Introduction
+
+This focused section addresses a CI warning caused by `actions/setup-go` cache
+configuration assuming `go.sum` at repository root. Charon stores Go module
+dependencies in `backend/go.sum`.
+
+### Research Findings
+
+Verified workflow inventory (`.github/workflows/**`):
+
+- All workflows using `actions/setup-go` were identified.
+- Five workflows already set `cache-dependency-path: backend/go.sum`:
+   - `.github/workflows/codecov-upload.yml`
+   - `.github/workflows/quality-checks.yml`
+   - `.github/workflows/codeql.yml`
+   - `.github/workflows/benchmark.yml`
+   - `.github/workflows/e2e-tests-split.yml`
+- Two workflows use `actions/setup-go` without cache dependency path and are
+   the warning source:
+   - `.github/workflows/caddy-compat.yml`
+   - `.github/workflows/release-goreleaser.yml`
+- Repository check confirms only one `go.sum` exists:
+   - `backend/go.sum`
+
+### Technical Specification (Minimal Fix)
+
+Apply a warning-only cache path correction in both affected workflow steps:
+
+1. `.github/workflows/caddy-compat.yml`
+    - In `Set up Go` step, add:
+       - `cache-dependency-path: backend/go.sum`
+
+2. `.github/workflows/release-goreleaser.yml`
+    - In `Set up Go` step, add:
+       - `cache-dependency-path: backend/go.sum`
+
+No other workflow behavior, triggers, permissions, or build/test logic will be
+changed.
+
+### Implementation Plan
+
+#### Phase 1 — Workflow patch
+
+- Update only the two targeted workflow files listed above.
+
+#### Phase 2 — Validation
+
+- Run workflow YAML validation/lint checks already used by repository CI.
+- Confirm no cache restore warning appears in subsequent runs of:
+   - `Caddy Compatibility Gate`
+   - `Release (GoReleaser)`
+
+#### Phase 3 — Closeout
+
+- Mark warning remediated once both workflows execute without the missing
+   `go.sum` cache warning.
+
+### Acceptance Criteria
+
+1. Both targeted workflows include `cache-dependency-path: backend/go.sum` in
+    their `actions/setup-go` step.
+2. No unrelated workflow files are modified.
+3. No behavior changes beyond warning elimination.
+4. CI logs for affected workflows no longer show the missing dependencies-file
+    warning.
+
+### PR Slicing Strategy
+
+- Decision: Single PR.
+- Rationale: Two-line, warning-only correction in two workflow files with no
+   cross-domain behavior impact.
+- Slice:
+   - `PR-1`: Add `cache-dependency-path` to the two `setup-go` steps and verify
+      workflow run logs.
+- Rollback:
+   - Revert only these two workflow edits if unexpected cache behavior appears.
+

+## PR-2 Security Patch Posture and Advisory Disposition
+
+- Date: 2026-02-23
+- Scope: PR-2 only (security patch posture + xcaddy patch retirement decision)
+- Upstream target: Caddy 2.11.x line (`2.11.1` candidate in this repository)
+- Inputs:
+  - PR-1 compatibility matrix: `docs/reports/caddy-compatibility-matrix.md`
+  - Plan authority: `docs/plans/current_spec.md`
+  - Runtime and bootstrap assumptions: `.docker/docker-entrypoint.sh`, `.docker/compose/docker-compose.yml`
+
+### 1) Final patch disposition
+
+| Patch target | Decision | Rationale (evidence-backed) | Rollback path |
+| --- | --- | --- | --- |
+| `github.com/expr-lang/expr@v1.17.7` | Retain | Enforced by current builder patching and CI dependency checks. | Keep current pin. |
+| `github.com/hslatman/ipstore@v0.4.0` | Retain | No PR-2 evidence supports safe retirement. | Keep current pin. |
+| `github.com/slackhq/nebula@v1.9.7` | Retire by default | Matrix evidence supports scenario `B`/`C`; default moved to `B` with rollback preserved. | Set `CADDY_PATCH_SCENARIO=A`. |
+
+### 2) Caddy 2.11.x advisory disposition
+
+| Advisory | Component summary | Exploitability | Evidence source | Owner | Recheck cadence |
+| --- | --- | --- | --- | --- | --- |
+| `GHSA-5r3v-vc8m-m96g` (`CVE-2026-27590`) | FastCGI `split_path` confusion | Not affected | Upstream advisory + Charon runtime path review (no FastCGI transport in default generated config path) | QA_Security | weekly |
+| `GHSA-879p-475x-rqh2` (`CVE-2026-27589`) | Admin API cross-origin no-cors | Mitigated | Upstream advisory + local controls: `CHARON_CADDY_ADMIN_API` now validated against internal allowlist and expected port 2019; production compose does not publish 2019 by default | QA_Security | weekly |
+| `GHSA-x76f-jf84-rqj8` (`CVE-2026-27588`) | Host matcher case bypass | Mitigated | Upstream advisory + PR-1 Caddy 2.11.x matrix compatibility evidence and Charon route/security test reliance on upgraded line | QA_Security | release-candidate |
+| `GHSA-g7pc-pc7g-h8jh` (`CVE-2026-27587`) | Path matcher escaped-case bypass | Mitigated | Upstream advisory + PR-1 matrix evidence and maintained security enforcement suite coverage | QA_Security | release-candidate |
+| `GHSA-hffm-g8v7-wrv7` (`CVE-2026-27586`) | mTLS client-auth fail-open | Not affected | Upstream advisory + Charon default deployment model does not enable mTLS client-auth CA pool configuration by default | QA_Security | on-upstream-change |
+| `GHSA-4xrr-hq4w-6vf4` (`CVE-2026-27585`) | File matcher glob sanitization bypass | Not affected | Upstream advisory + no default Charon generated config dependency on vulnerable matcher pattern | QA_Security | on-upstream-change |
+
+### 3) Admin API exposure assumptions and hardening status
+
+- Assumption: only internal Caddy admin endpoints are valid management targets.
+- PR-2 enforcement:
+  - validate and normalize `CHARON_CADDY_ADMIN_API`/`CPM_CADDY_ADMIN_API`
+  - host allowlist + expected port `2019`
+  - fail-fast startup on invalid/non-allowlisted endpoint
+- Exposure check: production compose defaults do not publish port `2019`.
+
+### 4) Runtime safety and rollback preservation
+
+- Runtime defaults keep `expr` and `ipstore` pinned.
+- `nebula` pin retirement is controlled by scenario switch, not hard deletion.
+- Emergency rollback remains one-step: `CADDY_PATCH_SCENARIO=A`.
+
+### Validation executed for PR-2
+
+| Command / Task | Outcome |
+| --- | --- |
+| `cd /projects/Charon/backend && go test ./internal/config` | PASS |
+| VS Code task `Security: Caddy PR-1 Compatibility Matrix` | PASS (A/B/C scenarios pass on `linux/amd64` and `linux/arm64`; promotion gate PASS) |
+
+Relevant generated artifacts:
+- `docs/reports/caddy-compatibility-matrix.md`
+- `test-results/caddy-compat/matrix-summary.csv`
+- `test-results/caddy-compat/module-inventory-*-go-version-m.txt`
+- `test-results/caddy-compat/module-inventory-*-modules.txt`
+
+### Residual risks / follow-up watch
+
+1. Caddy advisories with reserved or evolving CVE enrichment may change exploitability interpretation; recheck cadence remains active.
+2. Caddy bootstrap still binds admin listener to container interface (`0.0.0.0:2019`) for compatibility, so operator misconfiguration that publishes port `2019` can expand attack surface; production compose defaults avoid publishing this port.
+
+### PR-2 closure statement
+
+PR-2 posture decisions are review-ready: patch disposition is explicit, admin API assumptions are enforced, and rollback remains deterministic. No PR-3 scope is included.

+| Runtime posture + rollback | PASS | Default scenario shifted `A -> B` for PR-2 posture; rollback remains explicit via `CADDY_PATCH_SCENARIO=A`; admin API URL now validated and normalized at config load. |
 
-## Evidence Snapshot
+## Resolved Items
 
-- Targeted rerun passed for prior blocker tests.
-- Matrix run completed with full rows and PASS outcomes in isolated output.
-- Promotion gate condition met: Scenario A passed on linux/amd64 and linux/arm64.
-- Candidate path remains opt-in; default path remains stable.
+1. `check-version-match` mismatch fixed by syncing `.version` to `v0.19.1`.
+2. `frontend-type-check` hook stabilized to `npx tsc --noEmit` for deterministic pre-commit behavior.
 
-## Open Risks to Monitor
+## PR-2 Closure Statement
 
-- Matrix artifact contamination if shared output directories are reused.
-- Candidate behavior drift if default build args are changed in future slices.

-## Final Verdict
-
-PR-1 closure gates are satisfied for the compatibility slice.
+All PR-2 QA/security gates required for merge are passing. No PR-3 scope is included in this report.
