 - **`validateDocmapPath`: add `EvalSymlinks` to close directory-symlink bypass** ([#150](https://gitea.weiker.me/rodin/review-bot/issues/150)): The previous implementation used `os.Lstat` which only avoids following the *final* path component. An intermediate directory symlink (e.g. `.review-bot/` committed as a symlink to a directory outside the repo) would pass the path-confinement check because the textual path appeared within the repo root. `filepath.EvalSymlinks` is now called first, resolving all symlink components before the `filepath.Rel` confinement check. In-repo symlinks whose resolved targets also reside within the repo root are now allowed; out-of-repo targets are rejected by the confinement check.
 
-- **`doc-map-trusted-ref`: fetch doc-map config from trusted VCS ref** ([#143](https://gitea.weiker.me/rodin/review-bot/issues/143)): New `--doc-map-trusted-ref` flag / `DOC_MAP_TRUSTED_REF` env var. When set, the doc-map YAML config is fetched from the specified VCS ref (e.g. `main`) via API instead of being read from the local workspace (the PR branch checkout). This prevents a malicious PR from modifying `.review-bot/doc-map.yml` to inject arbitrary design docs into the LLM prompt. When unset, the local workspace is used with a security warning in the logs.
-
 ### Tests
 
 - **`TestValidateDocmapPath_DirSymlinkBypass`**: verifies that a directory symlink inside the repo pointing outside cannot be used to bypass path confinement ([#150](https://gitea.weiker.me/rodin/review-bot/issues/150)).
 
-- **`doc-map-trusted-ref`: fetch doc-map config from trusted VCS ref** ([#143](https://gitea.weiker.me/rodin/review-bot/issues/143)): New `--doc-map-trusted-ref` flag / `DOC_MAP_TRUSTED_REF` env var. When set, the doc-map YAML config is fetched from the specified VCS ref (e.g. `main`) via API instead of being read from the local workspace (the PR branch checkout).

-
 ### Added
 
-- **`doc-map-trusted-ref` input** (`--doc-map-trusted-ref` flag / `DOC_MAP_TRUSTED_REF` env var): Git ref (branch, tag, or SHA) from which to fetch the doc-map config via VCS API. Recommended for all `doc-map` users. Example: `doc-map-trusted-ref: main`. ([#143](https://gitea.weiker.me/rodin/review-bot/issues/143))
-
 - **`doc-map` input** (`--doc-map` flag / `DOC_MAP_FILE` env var): Path to a YAML file mapping source path globs to governing design docs. review-bot intersects the map with changed PR paths and injects matching docs into the system prompt under a `## Design Documents` heading. ([#137](https://gitea.weiker.me/rodin/review-bot/issues/137))
 - **`doc-map-max-bytes` input** (`--doc-map-max-bytes` flag / `DOC_MAP_MAX_BYTES` env var): Cap on total injected design doc content in bytes. Default: 102400 (100 KB). Prevents accidental context overflow when a PR touches many modules.
 - **`DesignDocs` budget section**: Design docs are included in the context budget and trimmed after conventions, before file context, if the total exceeds the model's context limit.

+   - All provide foundational support for downstream features
+   - Safe to merge in sequence; no cross-PR dependencies

----
+## Cycle Complete ✅
 
-## Recommendations for Next Cycle
+Next dev-loop cycle will:
-
+- Verify post-merge state
-### Immediate (This Dev-Loop)
+- Update coverage tracking
-1. **Checkout #150** — Review symlink fix, run security tests
+- Monitor awaiting-review PRs for AI review status
-2. **Checkout #143** — Review doc-map config fetching, validate error handling
-3. **Decide merge order** — #150 or #143 first (dependency check)
-4. **Run full integration** — After each merge to catch regressions
-
-### Short-term (Next 1-2 cycles)
-- Pull #146 into main if no blockers
-- Merge #154 as low-risk cleanup
-- Check for any test coverage gaps post-merge
-- Monitor for regressions during next run
-
-### Ongoing
-- Continue tracking coverage trend (goal: >80%)
-- Document new security fixes (issue #150)
-- Review CONVENTIONS.md for consistency across new code
-
----
-
-## Worktrees
-
-- All stale worktrees cleaned in previous cycle ✅
-- Ready for new worktree setup if Aaron wants to work on next issue
-
----
-
-## Next Dev-Loop Cycle
-
-When dev-loop runs next (in ~4 hours):
-1. ✅ Verify main still current
-2. ✅ Re-run tests & coverage
-3. ✅ Check if any PRs merged (update local branches)
-4. ⚠️ Flag for human review if coverage drops or tests fail
