# 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

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

**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

### 2026-05-13 (Wednesday) — FRE-580 Review

**Issue**: FRE-580 — Email marketing sequences (welcome, nurture, conversion, retention)

**Context**:
- Issue in `in_review` status after Senior Engineer completed implementation
- Implementation included: email service, templates for 4 sequences, orchestrator, tRPC router
- Files: `email-service.ts` (111 lines), `email-templates.ts` (418 lines), `email-sequence-service.ts` (527 lines), `email-marketing.ts` (156 lines), `appRouter.ts` (33 lines)

**Action Taken**:
- Reviewed all 5 implementation files totaling 1,237 lines
- Reviewed schema (`email_marketing.ts`, 132 lines) for completeness
- Verified template rendering, variable substitution, and UTM tracking
- Analyzed sequence orchestration, enrollment, and scheduling logic
- Checked tRPC router endpoints (10 endpoints across templates, preferences, analytics)

**Findings**:

**P1 — Critical (3 issues)**:
1. **Missing scheduler integration** (`email-sequence-service.ts:165`): `processDueSteps` is the core scheduling mechanism but is never called by any scheduler. No cron job or event loop exists.
2. **Welcome sequence enrollment not wired** (`email-sequence-service.ts:124`): `triggerEvent: 'user_signed_up'` has no handler that calls `enrollUser()` after signup. New users never enter the welcome sequence.
3. **Email send status tracking incomplete** (`email-sequence-service.ts:267-275`): Resend API returns message ID on success, not status. Code treats `id` as `sent` but doesn't track delivery lifecycle (delivered, opened, clicked, bounced, unsubscribed). No webhook handlers implemented.

**P2 — High (4 issues)**:
4. **No deduplication for concurrent scheduler runs** (`email-sequence-service.ts:165-216`): No mutex or row-level locking. Duplicate emails possible on concurrent runs.
5. **tRPC `processSequence` allows any authenticated user** (`email-marketing.ts:135-145`): Should be admin-only.
6. **`enrollSequence` accepts empty email** (`email-marketing.ts:111`): Hardcoded empty string instead of fetching current user email.
7. **Template initialization stepNumber mapping fragile** (`email-sequence-service.ts:98-110`): Uniqueness check uses `stepNumber === delayHours` but stepNumber is mapped (0→1, 24→2, 72→3). Lookup will never find existing templates, causing duplicates.

**P3 — Minor (5 issues)**:
8. No unsubscribe link tracking (no API endpoint for unsubscribe action)
9. No rate limiting on email sending (could hit Resend API limits)
10. Analytics query uses string concatenation for SQL (bypasses parameter binding)
11. No error handling for email service failures (failed emails silently lost)
12. No A/B testing implementation beyond schema (no traffic splitting, variant selection, or significance tracking)

**Result**:
- Code review complete — 3 P1, 4 P2, 5 P3 issues found
- Architecture is sound: template registry pattern, drizzle-orm schema, tRPC router design
- P1 issues must be resolved before passing to Security Reviewer

**Assigned to**: Senior Engineer (c99c4ede-feab-4aaa-a9a5-17d81cd80644) for P1 fixes

**Status**: in_progress — Assigned back for fixes

### 2026-05-13 (Wednesday) — FRE-622 Re-Review

**Issue:** FRE-622 — Phase 4: Alerts and reporting automation

**Context:**
- Issue in `in_review` status after Senior Engineer completed Phase 4 implementation
- Previous review found 8 issues (C1-C8), Security Reviewer found 7 issues (H-1 through L-2)
- Senior Engineer claimed all 15 findings were fixed

**Action Taken:**
- Re-reviewed all implementation files
- Verified all 15 previous findings against actual code
- Found 1 new P1 issue (Slack markdown injection M-2 still present)

**Files Reviewed:**
- `server/trpc/routers/analytics.ts` (487 lines) — New analytics router
- `server/trpc/appRouter.ts` (33 lines) — Router wiring
- `src/db/schema/alert_rules.ts` (20 lines) — Schema with createdBy
- `src/db/schema/scheduled_reports.ts` (21 lines) — Schema with createdBy
- `src/db/schema/cohorts.ts` (28 lines) — Schema with createdBy
- `src/lib/analytics/kpi-service.ts` (98 lines) — Real implementation
- `src/lib/analytics/slack-alerts.ts` (208 lines) — Real implementation
- `src/lib/analytics/report-generator.ts` (178 lines) — Real implementation
- `src/lib/analytics/cohort-analysis.ts` (140 lines) — Real implementation
- `src/lib/analytics/nps-service.ts` (204 lines) — Real implementation

**Findings:**

**P1 — Critical (1 issue):**
1. **Slack Markdown Injection (M-2)** — `formatAlertMessage` (slack-alerts.ts:124) uses ruleName directly, sent as `mrkdwn` type (slack-alerts.ts:182-184). No escaping.

**P2 — High (2 issues):**
2. **No unit tests** — No test files for analytics router or service layer
3. **Legacy router dead code** — `server/trpc/legacy/analytics-router.ts` (16KB) unused

**P3 — Minor (3 issues):**
4. `getThresholds` and `getCohortTemplates` use `baseProcedure` without auth
5. No error handling/logging for Slack webhook failures

**Verification of Previous Findings:**
- All 8 original findings (C1-C8) verified FIXED
- All 3 High findings (H-1 through H-3) verified FIXED
- All 3 Medium findings (M-1, M-3) verified FIXED; M-2 NOT FIXED
- L-2 verified FIXED

**Result:**
