+## Final Gaps: Detailed Implementation
+
+The following gaps were identified during a full audit of the plan vs implementation. Each takes a TDD approach.
+
+### G1: Complete computeWins — add baselines_ready, cooldown, improve back_in_range
+
+**Status of computeWins today:** Implements `personal_best` and `all_in_range` only. Missing `back_in_range` (needs prior state), `streak` (needs weekly history), `baselines_ready` (needs first-time flag), and per-metric 30-day cooldown.
+
+**Changes to `mobile/src/utils/experiments/computeWins.ts`:**
+
+1. **`baselines_ready`** — Accept an `isFirstBaseline: boolean` parameter. When true and at least one metric has `personal_status != null`, emit a one-time win. The caller (`my-body.tsx`) tracks this via AsyncStorage key `baselines_ready_win_shown`.
+
+2. **Cooldown** — Accept `recentWinDates: Record<string, string>` (metric_key → ISO date of last win). Skip personal_best for a metric if its last win was within 30 days. The caller persists this in AsyncStorage.
+
+3. **`back_in_range`** — Accept optional `previousStatuses: Record<string, string | null>` (metric_key → previous personal_status). When a metric was `'outside_bad'` and is now `'within'` or `'outside_good'`, emit a win. The caller persists the previous scorecard's statuses in AsyncStorage after each render.
+
+4. **`streak`** — Defer. Requires weekly aggregation of trend data across multiple sessions, which we don't have. Leave the TODO. This is the lowest-value win type.
+
+**Updated signature:**
+```typescript
+export function computeWins(
+  scorecard: MetricScore[],
+  opts?: {
+    isFirstBaseline?: boolean;
+    recentWinDates?: Record<string, string>;
+    previousStatuses?: Record<string, string | null>;
+    currentDate?: string;
+  },
+): WinEvent[]
+```
+
+**Tests (`mobile/src/utils/experiments/__tests__/computeWins.test.ts` — update existing):**
+- Returns `baselines_ready` win when `isFirstBaseline` is true and baselines exist
+- Does NOT return `baselines_ready` when `isFirstBaseline` is false
+- Skips personal_best for metric when recentWinDates shows win within 30 days
+- Does NOT skip when recentWinDates shows win >30 days ago
+- Returns `back_in_range` when metric transitioned from `outside_bad` to `within`
+- Does NOT return `back_in_range` when metric was already `within`
+- Does NOT return `back_in_range` when previousStatuses not provided
+
+**Wire in `my-body.tsx`:**
+- Read/write `baselines_ready_win_shown`, `recent_win_dates`, `previous_scorecard_statuses` from AsyncStorage
+- Pass to `computeWins` as opts
+- After rendering, persist current statuses for next comparison
+
+**Test count:** ~7 new + update existing
+
+---
+
+### G2: Starter pack returns respiratory_rate
+
+**File:** `supabase/functions/ai-engine/engines/starter-pack.ts`
+
+**Change:** Extract respiratory_rate from `sleep_sessions.vendor_metadata` the same way the compute-baselines function does. WHOOP stores it at `vendor_metadata.respiratory_rate`, Oura at `vendor_metadata.breath.average`. Average across sessions per day, include in `metricAverages` and `dailyHistory`.
+
+**Tests (add to `starter-pack.test.ts`):**
+- `daily_history.respiratory_rate` has entries when sleep sessions contain respiratory rate data
+- Metric averages include `respiratory_rate` when data exists
+- WHOOP respiratory_rate extracted from `vendor_metadata.respiratory_rate`
+- Oura respiratory_rate extracted from `vendor_metadata.breath.average`
+
+**Test count:** ~4
+
+---
+
+### G3: Insert user_cycle_reports on confirm + refine cycle_length_days
+
+**File:** `mobile/src/app/(tabs)/my-body.tsx`
+
+**Changes to `onCycleConfirm` callback:**
+1. After `updateProfile`, insert a row into `user_cycle_reports` via `supabase.from('user_cycle_reports').insert({ user_id, period_start_date, source: 'user_input' })`
+2. Query the last 3 `user_cycle_reports` rows for this user, compute the rolling average of intervals between consecutive `period_start_date` values, and update `cycle_length_days` on user_profiles.
+
+**Changes to `onCycleSubmit` callback (CycleInsightCard):**
+1. If a `last_period_date` is provided, also insert into `user_cycle_reports`.
+
+**Tests (add to `cycleConfirmDismiss.test.ts` or new file):**
+- After onCycleConfirm, a row is inserted into user_cycle_reports
+- After 3 confirmations, cycle_length_days is updated to the rolling average
+- After onCycleSubmit with a date, a row is inserted into user_cycle_reports
+
+**Test count:** ~3
+
+---
+
+### G4: Profile "Turn off" triggers recomputation and deletes cycle_reports
+
+**File:** `mobile/src/app/(tabs)/profile.tsx`
+
+**Changes to the "Turn off cycle tracking" handler:**
+1. After clearing cycle fields on user_profiles, call `supabase.functions.invoke('compute-baselines', { body: { user_id } })` to rebuild all-phase baselines.
+2. Delete all `user_cycle_reports` rows for this user: `supabase.from('user_cycle_reports').delete().eq('user_id', userId)`.
+3. Invalidate personalBaselines query cache.
+
+**Tests (add to `ProfileAboutYou.test.tsx`):**
+- Turning off cycle tracking calls compute-baselines
+- Turning off cycle tracking deletes user_cycle_reports rows
+- (These are callback verification tests — mock supabase.functions.invoke and supabase.from().delete())
+
+**Test count:** ~2
+
+---
+
+### G5: MetricScoreCard interim text and transition label
+
+**File:** `mobile/src/components/Experiments/MetricScoreCard.tsx`
+
+**Changes:**
+
+1. **"Building cycle-aware ranges..."** — When the score has `cycle_phase` set but `personal_status` is null (cycle tracking opted in but phase-specific baselines not ready yet), show: "Building your cycle-aware ranges... we need one full cycle of data."
+
+2. **"Back in your range"** — When the score has a new field `returned_to_range: boolean` (set by computeWins or buildMetricScorecard when detecting the transition), show "Back in your range" label.
+
+For (2), add `returned_to_range?: boolean` to MetricScore in types.ts and set it in computeWins or in my-body.tsx by comparing current vs previous statuses.
+
+**Tests (integration test additions to `health-snapshot-integration.test.tsx`):**
+- MetricScoreCard shows "Building your cycle-aware ranges" when cycle_phase set but personal_status null
+- MetricScoreCard shows "Back in your range" when returned_to_range is true
+
+**Test count:** ~2
+
+---
+
+### G6: CycleInsightCard real date picker
+
+**File:** `mobile/src/components/Experiments/CycleInsightCard.tsx`
+
+**Change:** Replace the stub date picker (auto-sets to 14 days ago) with a TextInput date field matching the pattern used in CycleConfirmationPrompt. User types YYYY-MM-DD or taps to select. Keep "I'm not sure" option.
+
+**Tests (integration test covers this):** Existing integration test verifies submit callback fires with the right values. No new tests needed — just implementation.
+
+**Test count:** 0
+
+---
+
+### G7: CycleConfirmationPrompt "once per cycle" guard
+
+**File:** `mobile/src/components/Experiments/CycleConfirmationPrompt.tsx`
+
+**Change:** Add `lastShownCycleDate: string | null` prop. If the current `estimatedDueDate` matches `lastShownCycleDate` (same cycle), return null. The caller persists this in AsyncStorage after the prompt is shown.
+
+**File:** `mobile/src/app/(tabs)/my-body.tsx` — read/write `cycle_confirm_last_shown_due_date` from AsyncStorage.
+
+**Tests:**
+- Prompt does not render when `lastShownCycleDate` matches current `estimatedDueDate`
+- Prompt renders when `lastShownCycleDate` is from a prior cycle
+
+**Test count:** ~2
+
+---
+
+### G8: HeroSummary improvement duration
+
+**File:** `mobile/src/components/Experiments/HeroSummary.tsx`
+
+**Change:** The improving metric sentence currently says "Your HRV has been improving." To add duration ("for 3 weeks"), `MetricScore` would need a `trend_duration_weeks` field. This requires the trend computation to output duration, which requires weekly aggregated data we don't have.
+
+**Decision:** Defer. The current sentence is accurate without the duration. Adding "for 3 weeks" requires changes to trendComputation, buildMetricScorecard, and the starter pack's daily history format. Low value relative to complexity.
+
+**Test count:** 0
+
+---
+
+### G9: Test gaps — MetricScoreCard and HealthSnapshot Phase 6/8 tests
+
+The plan specified 16 MetricScoreCard tests and 10 HealthSnapshot tests in Phases 6 and 8. These live in `.test.tsx` files in `__tests__/components/` which have a pre-existing Babel JSX parse issue. The integration test file (`health-snapshot-integration.test.tsx`) covers most of these paths end-to-end but runs via a separate command.
+
+**Fix:** Add the missing test assertions to the integration test file (which uses proper JSX compilation) rather than the broken `.test.tsx` files:
+
+- MetricScoreCard: "Building your personal baseline... X of 30 days" renders when daysOfData < 30
+- MetricScoreCard: "Building cycle-aware ranges..." renders during interim
+- MetricScoreCard: population safety callout not shown when flag is false (already covered)
+- MetricScoreCard: never renders red color (verify no element with red color style)
+- HealthSnapshot: shows CycleInsightCard with privacy text for qualifying user (already covered)
+- HealthSnapshot: does not show CycleInsightCard for male user (already covered)
+- HealthSnapshot: respiratory_rate card appears for WHOOP/Oura data (needs respiratory_rate in test data after G2)
+
+**Test count:** ~4 new integration test cases
+
+---
+
+### Implementation Order
+
+```
+G2 (respiratory_rate)     — independent, server-side
+G6 (date picker)          — independent, small UI fix
+G7 (once-per-cycle guard) — independent, small
+G3 (cycle reports insert) — independent, my-body.tsx
+G4 (profile turn-off)     — independent, profile.tsx
+G1 (computeWins complete) — depends on G3 for back_in_range testing
+G5 (MetricScoreCard text) — depends on G1 for returned_to_range
+G9 (integration tests)    — depends on G2, G5
+G8 (HeroSummary duration) — deferred
+```
+
+G2, G3, G4, G6, G7 are all independent and can run in parallel.
+
+### Total New Tests
+
+| Item | Tests |
+|------|-------|
+| G1: computeWins completion | ~7 |
+| G2: respiratory_rate in starter pack | ~4 |

+| G4: profile turn-off recomputation + cleanup | ~2 |
+| G5: MetricScoreCard interim + transition text | ~2 |
+| G6: Date picker | 0 |
+| G7: Once-per-cycle guard | ~2 |
+| G8: HeroSummary duration | 0 (deferred) |
+| G9: Integration test additions | ~4 |
+| **Total** | **~24 new tests** |
