- Cloud Functions: rewrite the module tree for the v2 migration (B0-B6d,
2026-07-08); add options.ts (global v2 setGlobalOptions, Cloud Run CPU
quota workaround), log.ts, the shared push/quietHours/idempotency/
pruneTokens/time infra under notifications/, releaseKey/, backup/,
the dates/onDate* triggers, couples/aggregateOutcomes, and the new
sendStreakReminder + sendThinkingOfYouCallable. Replace the single
onGamePartFinished with the four per-game part-finished triggers
shipped in B6c. Note the webhook is not deployed (RevenueCat project
not yet created; export commented out in functions/src/index.ts).
- Daily question lifecycle: replace the 'picks a random' description
with the new server-authoritative, mode-aware, deterministic picker
that mirrors the client's DailyModeResolver; add a Server-authoritative
sub-section with the frozen DOW -> mode map and the daily_fun_mc
exclusion. Note the couple-scan pagination + unseeded-pool skip.
- Billing: add the Purchases.logIn(firebaseAuth.currentUser!!.uid)
identity link (commit b99a8338) and the typed BillingException mapping.
Cross-link to the Webhook reliability section for the not-deployed state.
- iOS: fix the Repository layout iOS Crypto/ block (R24 E2EE code ships
in it; no longer 'intentionally empty'); correct the 'pairing from iOS
fails' claim (works for schemaVersion 2 path; schemaVersion 3 is
infrastructure-gated per IOS_E2EE_STATUS.md); correct the 'iOS couples
have no recovery path' claim (R24 batch 2 added iOS recovery phrase).
- TOC + anchors: add the new sub-anchors; fix three pre-existing broken
anchors (r10, ios-android-sealed-answer-bridge, recovery-phrase-change
desync). 30/30 anchors verified clean with a GFM slug checker.
- New landmines: BANNER-LIFE-001 (R30 game banner lifecycle; the B6c
per-game split means a new game also needs a per-game monitor hook)
and FUNCTIONS-V2-DEPLOY (2nd-gen deploy / CPU-quota / Eventarc
propagation pattern, the 'Changing from an HTTPS function to a
background triggered function' error and the launch-time quota
increase to restore 1 vCPU + concurrency 80).
- Engineering_Reference_Manual_Plan.md: add Phase 2 status entry.
