# HEARTBEAT.md -- Code Reviewer Heartbeat Checklist

Run this checklist on every heartbeat. This covers your code review responsibilities.

The base url for the api is localhost:8087

**IMPORTANT: Use the Paperclip skill for all company coordination.**

## 1. Identity and Context

- `GET /api/agents/me` -- confirm your id, role, and chainOfCommand.
- Check wake context: `PAPERCLIP_TASK_ID`, `PAPERCLIP_WAKE_REASON`, `PAPERCLIP_WAKE_COMMENT_ID`.

## 2. Local Planning Check

1. Read today's plan from `$AGENT_HOME/memory/YYYY-MM-DD.md` under "## Today's Plan".
2. Review each planned item: what's completed, what's blocked, and what up next.
3. For any blockers, resolve them yourself or escalate to CTO.
4. If you're ahead, start on the next highest priority.
5. **Record progress updates** in the daily notes.

## 3. Approval Follow-Up

If `PAPERCLIP_APPROVAL_ID` is set:

- Review the approval and its linked issues.
- Close resolved issues or comment on what remains open.

## 4. Get Assignments

- `GET /api/companies/{companyId}/issues?assigneeAgentId={your-id}&status=todo,in_progress,in_review,blocked`
- Prioritize: `in_progress` first, then `in_review` (these are review tasks waiting for you), then `todo`. Skip `blocked` unless you can unblock it.
- The `opencode_local` adapter creates a silent run when `in_review` tasks are assigned to you. This is expected — the run stays quiet until you actively check out the issue. Ignore the run; focus on the task.
- If there is already an active run on an `in_progress` or `in_review` task, skip it (someone else is handling it).
- If `PAPERCLIP_TASK_ID` is set and assigned to you, prioritize that task.

## 5. Checkout and Work

- Always checkout before working: `POST /api/issues/{id}/checkout`.
- Never retry a 409 -- that task belongs to someone else.
- Do the work. Update status and comment when done.

## 6. Code Review Responsibilities

As a Code Reviewer, you ensure code quality before security review:

### Review Scope
- Review the scope of work described in the issue
- Check all files touched by the engineer
- Verify the implementation matches the requirements

### Code Quality Review
- Check for correctness, maintainability, and performance
- Ensure code follows project conventions
- Look for potential bugs and edge cases
- Verify tests are adequate

### Review Decision
When you complete a code review:
1. **If no issues found:** Mark issue status unchanged (stays `in_review`), assign to Security Reviewer, add a comment summarizing your review
2. **If issues found:** Keep issue as `in_review`, assign back to the original engineer with detailed comments explaining the issues

### Passing Work
- Assign to Security Reviewer when code looks good
- Assign back to engineer when changes are needed

## 7. Fact Extraction

1. Check for new conversations since last extraction.
2. Extract durable facts to the relevant entity in `$AGENT_HOME/life/` (PARA).
3. Update `$AGENT_HOME/memory/YYYY-MM-DD.md` with timeline entries.
4. Update access metadata (timestamp, access_count) for any referenced facts.

## 8. Exit

- Comment on any in_progress work before exiting.
- If no assignments and no valid mention-handoff, exit cleanly.

---

## Code Review Pipeline

**Your workflow:**
1. Receive issue in `in_review` status assigned to you
2. Checkout the issue: `POST /api/issues/{id}/checkout`
3. Review the code: scope, files touched, implementation quality
4. Add a comment with your review findings:
   - If good: summarize review and assign to Security Reviewer
   - If issues: detail the issues and assign back to the engineer

**Engineering team:**
- Senior Engineer - feature development and mentorship
- Founding Engineer - architecture and core systems
- Junior Engineer - learning and executing defined tasks

**Review flow:**
- Engineer → Code Reviewer → Security Reviewer → Done

- P1: Deploy workflow circular dependency (`needs.detect-environment` self-reference)
- P1: ALB health check URL hardcoded format
- P1: Secrets module constructs incorrect DB/REDIS URLs (wrong hostname pattern)
- P1: Rollback never triggers (health-check never sets failure)
- P2: ECS health check uses `wget` (not in Alpine)
- P2: CI terraform plan lacks AWS creds
- P2: Dockerfiles use `npm ci` but project uses `pnpm`
- P2: Overly permissive ECS task role

**Action Taken**:
- Checked out orphaned in_review issue (previous reviewer agent removed)
- Reviewed 3 files: voiceprint.js (259 lines), run.sh (69 lines), .env.example (19 lines)
- Mapped issue specs against actual API routes
- Identified 2 P1, 3 P2, 1 P3 issues

**Findings**:
- P1: generateAudioPayload claims 96KB but sends ~2.7KB — misrepresents load profile
- P1: handleSummary passed always false — metric?.thresholds?.every chokes on metrics without thresholds (same bug as FRE-4928)
- P2: Failed enrollments/verifications return random UUID, polluting model-retrieval success rates
- P2: run.sh mixed case has empty heredoc redirect to stdin
- P2: New scripts not wired into CI — load-test.yml runs old script with wrong endpoints

- Compared against voiceprint.js pattern and CI pipeline
- Verified P99 thresholds match spec (login: 200ms, logout: 100ms, refresh: 150ms)
- Verified 500 req/s / 5 min configuration

**Findings**:
- P1: VU iteration rate ≠ HTTP request rate — mixedWorkload makes 2-3 HTTP calls per iteration, actual load is 1000-1500 RPS instead of 500
- P1: run.sh individual scenario commands fail — endpointScenarios not merged into options.scenarios, invisible to k6 --scenario
- P1: Unique email per login creates ~60K accounts in 5 min — unrealistic load pattern
- P2: Logout sends access_token in both body + Bearer header (redundant/wrong API contract)
- P2: handleSummary passed always false — iterates over all metrics including ones without thresholds
- P3: Dead code (endpointScenarios export), no CI integration

**Result**:
- Code review complete — 3 P1, 2 P2, 2 P3 issues found
- Assigned back to Senior Engineer for fixes
- Status moved to in_progress

- Reviewed `internal/mail/client_test.go` (1386 lines, 46 tests)
- Compared against source `client.go` and `api/client.go`

**Findings**:
- P1: Compile error — `NewProtonMailClient(cfg)` uses old 1-arg signature, but commit `691a2ac` changed to 2-arg `(cfg, refresher)`. 5 call sites affected.
- P1: `TestListMessages_APIError` — 401 triggers session refresh (new code), test expects `"invalid token"` but gets `"refresh failed"` error.

**Action Taken**:
- Checked out issue for re-review after commit `619a804`
- Verified all P0-P3 fixes from first-pass review
- Verified CTO's Clone() context correction

**Verified Fixes**:

- Error messages: Clear and descriptive for debugging

**Code Quality**:
- ✅ Clean separation of concerns (refresh logic in SessionRefresher interface)
- ✅ Proper error wrapping with `%w` for error chain preservation
- ✅ Thread-safe auth header updates via mutex
- ✅ Response body properly closed before retry
- ✅ Follows Go best practices for HTTP client implementation

**Result**:
- All first-pass findings successfully addressed
- Implementation matches go-proton-api pattern (client.go:doRes() -> authRefresh())

### 2026-05-11 (Monday) — FRE-5146 Review

**Issue**: FRE-5146 — Security Review: PremiumAnalyticsService

**Context**:
- Issue in `in_progress` status for security review of PremiumAnalyticsService
- Related to FRE-5136 (Premium Analytics Dashboard implementation)
- Service file: `/home/mike/code/Nessa/Nessa/Services/PremiumAnalyticsService.swift` (802 lines)

**Action Taken**:
- Reviewed PremiumAnalyticsService.swift (802 lines) - comprehensive analytics service
- Reviewed AnalyticsManager.swift (60 lines) - event tracking and metrics
- Reviewed WorkoutHistoryService.swift (68 lines) - workout data access
- Analyzed actor-based concurrency, caching, rate limiting implementation
- Reviewed data models: WorkoutAnalytics, PerformanceReport, Insights, Recommendations
- Evaluated predictive analytics: injury risk, plateau detection, optimal training load

**Findings**:

**P1 - Critical (4 issues)**:
1. **Incorrect userId in WorkoutAnalytics** (line 434): Uses `filter.timeRange.startDate.ISO8601Format()` instead of actual `userId` parameter
2. **Rate limit error semantics** (line 218): Throws `insufficientData` for rate limit, should use dedicated error
3. **Unsafe force unwrap in CSV export** (line 335): `csvData.data(using: .utf8)!` could crash
4. **Empty PDF implementation** (line 341-345): Returns `Data()` placeholder without actual PDF generation

**P2 - High (4 issues)**:
5. **Cache never invalidated** (lines 196-197): analyticsCache and reportCache grow unbounded
6. **Hardcoded expected workouts** (line 456): Consistency score assumes 3 workouts/week
7. **Benchmark uses mock data** (line 564-565): Hardcoded `benchmarkAvg = 0.75`
8. **Performance trend edge case** (line 470-472): Uneven splits for odd workout counts

**P3 - Minor (5 issues)**:
9. **HealthKit not integrated** (line 358): Status checked but data not used in calculations
10. **Unused protocol method** (line 711): `AnalyticsManagerProtocol.calculateMetrics` shadowed
11. **Date formatter not cached** (line 798-800): Creates new formatter on each call
12. **Missing filter validation** (line 241-246): minDuration filter not validated
13. **Magic number thresholds** (lines 369, 377, 385): Hardcoded confidence thresholds

**Result**:
- Code review complete — 4 P1, 4 P2, 5 P3 issues found
- Architecture is sound: actor-based concurrency, protocol dependencies, comprehensive features
- P1 issues must be resolved before passing to Security Reviewer

**Assigned to**: Founding Engineer for P1 fixes

### 2026-05-11 (Monday) — FRE-5146 Second-Pass Verification

**Issue**: FRE-5146 — Security Review: PremiumAnalyticsService

**Context**:
- Issue was in `in_review` status awaiting P1 fixes from previous review
- Required verification that all 4 P1 issues were addressed

**Action Taken**:
- Reviewed PremiumAnalyticsService.swift (802 lines) to verify P1 fixes
- Checked lines 436, 217, 331, and 338-343 for the 4 P1 fixes

**Findings**:
All 4 P1 issues still present:
1. ❌ Line 436: `userId: filter.timeRange.startDate.ISO8601Format()` — still uses date instead of userId
2. ❌ Line 217: `throw PremiumAnalyticsError.insufficientData` — still uses wrong error semantic
3. ❌ Line 331: `data(using: .utf8)!` — still has force unwrap
4. ❌ Lines 338-343: `data: Data()` — still has empty PDF placeholder

**Result**:
- Second-pass verification complete — no P1 fixes applied yet
- Issue remains in `in_progress` status
- Assigned to Founding Engineer (d20f6f1c-1f24-4405-a122-2f93e0d6c94a) for P1 fixes

- Assigned back to Founding Engineer for fixes
- Status moved to in_progress

**Status**: Done — Passed with issues, assigned to Founding Engineer


### 2026-05-13 (Wednesday) — FRE-4764 Review

**Issue**: FRE-4764 — Improve retry logic, rate limiting, and error handling to match official library

**Context**:
- Issue in `in_review` status after Senior Engineer completed implementation
- Implementation included: structured error codes, NetError, connection monitoring, HV handling, exponential backoff with jitter
- Files: `internal/api/client.go` (553 lines), `internal/mail/client_test.go` (1390 lines)

**Action Taken**:
- Reviewed `internal/api/client.go`: error codes, NetError, RetryConfig, executeWithRetry, RateLimiter, StatusObserver
- Reviewed `internal/mail/client_test.go`: 53 route handlers, 46 test cases
- Verified route correctness: `/mail/v4/messages/*` endpoints, HTTP methods, response formats
- Analyzed resource management on error paths
- Checked for race conditions and thread safety

**Findings**:

**P1 — Critical (2 issues)**:
1. **Resource leak on retry exhaustion** (`internal/api/client.go:418-440`): When retries exhausted with `lastErr` set, `lastResp.Body` is never closed — connection pool exhaustion under failure
2. **Context cancellation response leak** (`internal/api/client.go:343-344`): When context cancelled during retry backoff delay, `lastResp.Body` is leaked

**P2 — High (3 issues)**:
3. **Unreachable code in `shouldRetryError`** (`internal/api/client.go:465-486`): `NetError` check is unreachable because `net.OpError` always matches first via `errors.As` unwrapping
4. **RateLimiter `Wait()` GC pressure** (`internal/api/client.go:277-298`): Creates new slice on every call instead of in-place filtering
5. **Race condition on auth refresh retry** (`internal/api/client.go:381-386`): Retry response body not closed when `doSingleRequest` fails after auth refresh

**P3 — Minor (3 issues)**:
6. **Thread-unsafe rand jitter** (`internal/api/client.go:523`): Uses `math/rand` without locking
7. **Missing error code constants**: SessionExpired (10005), TokenExpired (10006), AccountSuspended (10050), QuotaExceeded (10011)
8. **Test route ambiguity** (`internal/mail/client_test.go:72-82`): Generic handler matches multiple operations

**Test Coverage Gaps**:
- No retry logic tests (backoff, jitter, Retry-After parsing)
- No connection monitoring tests
- No HV handling tests
- No rate limiter tests
- No concurrent auth refresh test

**Result**:
- Code review complete — 2 P1, 3 P2, 3 P3 issues found
- P1 response body leaks must be fixed before passing
- Reassigned to Senior Engineer for P1 fixes

**Status**: in_progress — Assigned back to Senior Engineer
