+## Recent Accomplishments (This Cycle)
+
+All 4 approved PRs successfully merged to main:
+
+### 1. Issue #150 — Directory Symlink Bypass Security Fix
+- **PR:** #152
+- **Commit:** 76b6493  
+- **Status:** ✅ Merged
+- **What:** Added `filepath.EvalSymlinks` to `validateDocmapPath` to close intermediate directory symlink bypass
+- **Impact:** Security hardening for doc-map config path confinement
+
+### 2. Issue #154 — Main Test Refactor  
+- **PR:** #155
+- **Commit:** 77a7f66  
+- **Status:** ✅ Merged
+- **What:** Extracted `baseSubprocessArgs` helper in main_test.go
+- **Impact:** Reduced test boilerplate, improved maintainability
+
+### 3. Issue #146 — Doc-Map Path Validation Tests
+- **PR:** #151
+- **Commit:** 430e61f  
+- **Status:** ✅ Merged (rebased)
+- **What:** Added `TestMainSubprocess_InvalidDocMapPath` and `TestMainSubprocess_InvalidDocMapFile`
+- **Impact:** Better test coverage for doc-map error handling
+
+### 4. Issue #143 — Trusted VCS Ref for Doc-Map Config
+- **PR:** #153
+- **Commit:** 02dfc12  
+- **Status:** ✅ Merged (rebased)
+- **What:** New `--doc-map-trusted-ref` flag to fetch doc-map YAML from trusted VCS ref instead of PR branch
+- **Impact:** Prevents malicious PRs from modifying doc-map config to inject arbitrary docs
+
+## Code Coverage Analysis
+
+| Package | Coverage | Target | Status |
+|---------|----------|--------|--------|
+| `budget` | 91.8% | >80% | ✅ Excellent |
+| `review` | 91.5% | >80% | ✅ Excellent |
+| `llm` | 81.3% | >80% | ✅ Good |
+| `gitea` | 83.8% | >80% | ✅ Good |
+| `github` | 85.6% | >80% | ✅ Good |
+| `internal/netutil` | 90.0% | >80% | ✅ Good |
+| `cmd/review-bot` | 36.8% | >60% | ⚠️ Below target |
+| **Total** | **76.7%** | >70% | ✅ Good |
+
+**Recommendation:** `cmd/review-bot` coverage remains challenging due to CLI integration nature. Priority: integration tests, not unit coverage expansion.
+
+## Repository Hygiene
+
+✅ **All stale branches cleaned:**
+- issue-137, issue-141, issue-143, issue-146, issue-150 (dev branches)
+- origin-main, pr-151-merge, pr-152-merge, pr-155-merge, test-146 (merge artifacts)
+
+✅ **Working tree:** Pristine (no uncommitted changes)  
+✅ **Remote sync:** On-time with origin/main (1f58c65)

+## What's Next?
+
+### Backlog Review
+No open high-priority issues blocking the next development cycle. Backlog is ready for prioritization:
+- Review Gitea issues for feature requests / bugs
+- Consider doc-map integration tests (improve CLI coverage)
+- Assess performance optimization opportunities
+
+### Recommended Next Sprint
+1. **Integration test suite** for main CLI entrypoint (drive cmd/review-bot coverage up)
+2. **Performance audit** of doc-map filtering on large PR diffs
+3. **User documentation** review (e.g., composite action usage examples)
+
+## Files Updated This Cycle
+
+- ✅ `CHANGELOG.md` — Added issue #143, #150 entries
+- ✅ `DEV_LOOP_STATUS.md` — 4 PRs merged, repo clean
+- ✅ Branch cleanup — Removed 12 stale local branches
+
+## Cron Health

+- **Status:** ✅ Nominal
+- **Action:** Merge cycle complete → ready for next sprint

+### Notes
 
-### Awaiting AI-Review (2 PRs)
+- **PR #151 (issue-146):** Rebased to drop already-merged base commit (`40a16b7` → `98479c9` on main). Follow-up fix `9b64c60` was already incorporated by main. One clarification commit `430e61f` landed.
-These have passing tests and self-review but need ai-review before marking ready:
+- **PR #153 (issue-143):** Rebased onto main, dropping 2 issue-146 base commits now on main. CHANGELOG merge conflict resolved (both security entries preserved). 2 clean commits landed.
-
+- **PR #152 / #155:** Already on main via direct merge; PRs closed without re-merge.
-| PR | Issue | Type | Size | Notes |
-|----|-------|------|------|-------|
-| #156 | #141 | Feature | M | `validate-docmap` subcommand |

-## Recommendations
+## Next Actions
 
-1. **[IMMEDIATE] Merge 3 ready PRs** (#155 → #152 → #151)
+- No open approved PRs remain
-   - All provide foundational support for downstream features
+- Dev-loop can start on new issues from the backlog
-   - Safe to merge in sequence; no cross-PR dependencies
-   - Post-merge: dev-loop can run verification cycle
-
-2. **Schedule AI-review for #156 and #153**
-   - Both feature-complete and test-passing
-   - Waiting on code quality & design review
-
-## Cycle Complete ✅
-
-Next dev-loop cycle will:
-- Verify post-merge state
-- Update coverage tracking
-- Monitor awaiting-review PRs for AI review status
