 - **Ignore Files**: When creating new file types, directories, or build artifacts, ALWAYS check and update `.gitignore`, `.dockerignore`, and `.codecov.yml` to ensure they are properly excluded or included as required.
 - The root `Dockerfile` builds the Go binary and the React static assets (multi-stage build).
 - Branch from `feature/**` and target `development`.
+
+## CI/CD & Commit Conventions
+- **Docker Builds**: The `docker-publish` workflow skips builds for commits starting with `chore:`.
+- **Triggering Builds**: To ensure a new Docker image is built (e.g., for testing on VPS), use `feat:`, `fix:`, or `perf:` prefixes.
+- **Beta Branch**: The `feature/beta-release` branch is configured to ALWAYS build, overriding the skip logic.

+# Beta Release Draft Pull Request
+
+## Overview
+This draft PR merges recent beta preparation changes from `feature/beta-release` into `feature/alpha-completion` to align the alpha integration branch with the latest CI, workflow, and release process improvements.
+
+## Changes Included
+1. Workflow Token Updates
+   - Replaced deprecated `CPMP_TOKEN` usage with `CPMP_TOKEN` per new GitHub token naming restrictions.
+   - Ensured consistent secret reference across `release.yml` and `renovate_prune.yml`.
+2. Release Workflow Adjustments
+   - Fixed environment variable configuration for release publication.
+   - Maintained prerelease logic for alpha/beta/rc tags.
+3. CI Stability Improvements
+   - Prior earlier commits (already merged previously) included action version pinning for reproducibility and security.
+4. Docker Build Reliability
+   - (Previously merged) Improvements to locate and package the `dlv` binary reliably in multi-arch builds.

+# Beta Release Draft Pull Request
+
+## Overview
+This draft PR merges recent beta preparation changes from `feature/beta-release` into `feature/alpha-completion` to align the alpha integration branch with the latest CI, workflow, and release process improvements.
+
+## Changes Included (Summary)
+- Workflow token migration (`CPMP_TOKEN` → `CPMP_TOKEN`) across release and maintenance workflows.
+- Stabilized release workflow prerelease detection and artifact publication.
+- Prior (already merged earlier) CI enhancements: pinned action versions, Docker multi-arch debug tooling reliability, dynamic `dlv` binary resolution.
+- Documentation updates enumerating each incremental workflow/token adjustment for auditability.
+
+## Commits Ahead of `feature/alpha-completion`
+(See `docs/beta_release_draft_pr.md` for full enumerated list.) Latest unique commit: `5727c586` (refreshed body snapshot).
+
+## Rationale
+Ensures alpha integration branch inherits hardened CI/release pipeline and updated secret naming policy before further alpha feature consolidation.
+
+## Risk & Mitigation
+- Secret Name Change: Requires `CPMP_TOKEN` to exist. Mitigation: Verify secret presence before merge.
+- Workflow Fan-out: Reusable workflow path validated locally; CI run (draft) will confirm.
+
+## Follow-ups (Out of Scope)
+- Frontend test coverage improvements (ProxyHostForm).
+- Additional beta observability and import validation tasks.
+
+## Checklist
+- [x] YAML lint (pre-commit passed)
+- [x] Secret reference consistency
+- [x] Release artifact list intact
+- [ ] Draft PR CI run (pending after opening)
+
+## Requested Review Focus
+1. Confirm `CPMP_TOKEN` availability.
+2. Sanity-check release artifact matrix remains correct.
+3. Spot any residual `CPMP_TOKEN` references missed.
+
+---
+Generated draft to align branches; will convert to ready-for-review after validation.

+# Beta Release Draft Pull Request
+
+## Overview
+Draft PR to merge hardened CI/release workflow changes from `feature/beta-release` into `feature/alpha-completion`.
+
+## Highlights
+- Secret token migration: all workflows now use `CPMP_TOKEN` (GitHub blocks new secrets containing `GITHUB`).
+- Release workflow refinements: stable prerelease detection (alpha/beta/rc), artifact matrix intact.
+- Prior infra hardening (already partially merged earlier): pinned GitHub Action SHAs/tags, resilient Delve (`dlv`) multi-arch build handling.
+- Extensive incremental documentation trail in `docs/beta_release_draft_pr.md` plus concise snapshot in `docs/beta_release_draft_pr_body_snapshot.md` for reviewers.
+
+## Ahead Commits (Representative)
+Most recent snapshot commit: `308ae5dd` (final body content before PR). Full ordered list in `docs/beta_release_draft_pr.md`.
+
+## Review Checklist
+- Secret `CPMP_TOKEN` exists and has required scopes.
+- No lingering `CPMP_TOKEN` references beyond allowed GitHub-provided contexts.
+- Artifact list (frontend dist, backend binaries, caddy binaries) still correct for release.
+
+## Risks & Mitigations
+- Secret rename: Mitigate by verifying secret presence before merge.
+- Workflow call path validity: `docker-publish.yml` referenced locally; CI on draft will validate end-to-end.
+
+## Deferred Items (Out of Scope Here)
+- Frontend test coverage improvements (ProxyHostForm).
+- Additional beta observability and import validation tasks.
+
+## Actions After Approval
+1. Confirm CI draft run passes.
+2. Convert PR from draft to ready-for-review.
+3. Merge into `feature/alpha-completion`.
+
+## Request
+Please focus review on secret usage, workflow call integrity, and artifact correctness. Comment with any missed token references.
