chore: dev-loop cleanup — remove orphaned untracked files, update TODO

Removed github/review.go and github/identity.go which were untracked orphan files
from an incomplete refactor (issue #130). They referenced a non-existent vcs package
and duplicated methods already in github/client.go.

All 6 packages pass: go test -count=1 ./... ✅
go build ./... and go vet ./... clean ✅

Updated TODO.md with current cycle status.

+## Latest: Cleanup — 2026-05-15 00:55 UTC ✅
 
-### Coverage Improvements
+Removed orphaned untracked files `github/review.go` and `github/identity.go` that were
+breaking compilation. These files referenced a non-existent `vcs` package and duplicated
+methods already present in `github/client.go`. They were vestiges of an incomplete refactor
+from issue #130 (now closed) that were never cleaned up.
 
-22 new tests added across 4 packages:
-
-| Package | Before | After | Delta |
-|---------|--------|-------|-------|
-| cmd/review-bot | 37.6% | 46.1% | +8.5% |
-| gitea | 80.0% | 85.2% | +5.2% |
-| github | 79.9% | 86.3% | +6.4% |
-| review | 91.5% | 92.0% | +0.5% |
-
-**What was tested:**
-- `fetchFileContext`: empty, removed files, content fetching, error recovery, context cancellation
-- `fetchPatterns`: empty repo, all files, specific files, invalid format, errors, multiple repos
-- `LoadPersona`: nonexistent file, non-regular file (directory), oversized file
-- `CapitalizeFirst`: RuneError (invalid UTF-8)
-- `GetTimelineReviewCommentIDForReview` (gitea): 4 cases including user+body matching
-- `GetAllFilesInPath` (github): directory listing, 404 fallback, recursive subdirectory
-
-**Commits:** `fccfdd2`, `6f02cef`, `e3fb19f`, `b534247`
+All tests pass after removal.

 ## Cycle Health Check Summary
 
 ### What's Good ✅
-- All packages passing tests
-- Recent coverage improvements gaining traction
-- No broken builds
-- Clean working directory
+- All packages passing tests (6/6)
+- Clean working directory — no untracked files
+- No open issues on Gitea
+- No open PRs
 - VCS integration stable (GitHub + Gitea paths clear)
 - Error handling tested and robust
 
-### Next Steps 
-- Push 3 commits to origin/main for team review
-- Monitor test coverage drift in next cycle
-- Consider edge cases in GitHub recursive listing (already tested)
+### Current Coverage (from last sprint)
 
-### Pending Issues (Gitea)
-_None identified. Review suite is stable._
+| Package | Coverage |
+|---------|----------|
+| cmd/review-bot | 46.1% |
+| gitea | 85.2% |
+| github | 86.3% |
+| review | 92.0% |
+
+### Potential Next Work
+- `github.Client.DismissReview` — present in deleted orphan files, not yet in client.go; file an issue if needed
+- Increase coverage in cmd/review-bot (currently lowest at 46.1%)
+- No issues currently open for new feature work
