chore: dev-loop health check — PR #138 ready for merge at 2026-05-15 03:33 UTC

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 Delivered: Issue #130 ✅
-
-### GitHub API + VCS Routing Complete
-
-**Phase 1: GitHub API Methods** ✅
-- 12+ methods implemented in `github/client.go`
-- GetPullRequest, GetPullRequestDiff, GetPullRequestFiles
-- GetCommitStatuses, GetFileContent, ListContents, GetAllFilesInPath
-- PostReview, ListReviews, DeleteReview, GetAuthenticatedUser, RequestReviewer
-
-**Phase 2: VCS Abstraction** ✅
-- `vcsClient` interface (GitHub + Gitea)
-- `giteaExtClient` interface (Gitea-specific ops)
-- Adapters for both platforms
-- URL-based auto-detection (github.com → GitHub, else Gitea)
-- `--vcs-type` flag and `VCS_TYPE` env override
-
-**Quality Metrics** ✅
-- 474 lines of GitHub client tests
-- 82 lines of routing tests
-- 361 lines of VCS adapter code
-- Security review: APPROVED (MINOR: URL heuristic note)
-- All tests passing; go vet clean
-
-**Known Limitations** (Documented)
-- GitHub: Can only delete PENDING (draft) reviews, not submitted (handled gracefully)
-- GitHub pagination: per-page=100 with Link header checking
-- Check-runs: Uses statuses API; check-runs deferrable to future enhancement

-
-## Next Phase: Backlog Priorities
-
-### Priority 1: PR Submission
-**Issue:** #132+ (create)
-**Goal:** Enable review-bot to create PRs (not just post reviews)
-**Scope:** PR creation flow, commit logic, test coverage
-**Est. Time:** 3–5 days
-**Impact:** Enable automated improvements, fix suggestions with diff context
-
-### Priority 2: GitHub Enterprise Support
-**Goal:** Explicit testing & routing for GitHub Enterprise
-**Gap:** Enterprise URL patterns, /api/v3 suffix handling, token scopes
-**Scope:** Tests, URL routing, documentation
-**Est. Time:** 2–3 days
-**Impact:** Enable enterprise customers, reduce integration risk
-
-### Priority 3: Performance & Observability
-**Areas:**
-- Load testing under concurrent reviews
-- Metrics collection (review latency, LLM token usage, API call counts)
-- Audit logging for compliance workflows
-- Dashboard (review history, metrics, team analytics)
-**Est. Time:** 5–7 days
-**Impact:** Operational confidence, troubleshooting, compliance
-
-### Priority 4: Enhanced Context
-**Opportunities:**
-- Semantic code understanding (AST-based analysis for specific languages)
-- Project-specific review rules (.review-bot.yaml in repo root)
-- Team-level customization
-**Est. Time:** 7–10 days
-
----
-
-## Dev Loop Schedule
-
-- **Interval:** 4 hours
-- **Next check:** ~6:10 AM UTC (May 15)
-- **Health:** ✅ Optimal — all systems running
-- **Status:** Ready for next phase work
