Trace data revealed subscription_subscriptionsettings was consuming
1,983s of cumulative DB time per day (180× more than the next-largest
table) for a 32-byte singleton row of admin-toggleable global flags.
Root cause was a 30-second poll loop in monitoring.Service per pod
plus uncached reads on every authed status check / CreateResidence /
Stripe webhook. Fix is layered:
1. Redis cache for SubscriptionSettings — same shape as the
residence-IDs cache. 30-min TTL, explicit invalidation on admin
write. New CacheService.{Cache,GetCached,Invalidate}SubscriptionSettings
plus a cachedSubscriptionSettings helper in services/.
2. SubscriptionService, StripeService, and both admin handlers
(settings + limitations) now read through the cache. Admin write
handlers invalidate so toggles propagate cluster-wide within ms
instead of waiting for the TTL.
3. monitoring.Service.syncSettingsFromDB also reads from Redis first
(raw redis.Client to avoid a services→monitoring import cycle).
Polling interval bumped 30s → 5min. Combined with Redis-shared
cache, cluster-wide DB hits from this poll go from ~480/hour to
~2/hour — a 240× reduction.
4. StripeService.CreateCheckoutSession now takes ctx so the cached
settings span (and the Stripe webhook trace) stay attached to the
request. Handler call site updated.
5. Admin handlers' direct h.db.First calls switched to
db.WithContext(ctx) so the resulting orphan SQL spans nest under
the admin request span in Jaeger.
Net DB query rate for subscription_subscriptionsettings should drop
from 0.101/sec to ~0/sec with occasional invalidation-driven refills,
and the table's cumulative DB time from 1,983s/day to ~10s/day.

Every public method on these five services now takes ctx context.Context as
the first arg and routes its repo calls through .WithContext(ctx). With
TaskService and ResidenceService already migrated, this means every
in-process service that touches Postgres now produces a flame graph in
Jaeger where the SQL spans nest under the parent HTTP request span.
Endpoints now fully traced (HTTP → service → SQL):
- /api/auth/login, /register, /logout, /me, /verify-email, /resend-verification
- /api/auth/forgot-password, /verify-reset, /reset-password, /update-profile
- /api/contractors/* (CRUD + favorite + by-residence + tasks)
- /api/documents/* (CRUD + activate/deactivate + image upload/delete)
- /api/notifications/* (list, count, mark-read, prefs, devices)
- /api/subscription/* (status, purchase, cancel, triggers, promotions)
- All previously-migrated /api/tasks/* and /api/residences/* paths
Internal helpers also threaded:
- TaskService.sendTaskCompletedNotification → forwards ctx
- TaskService.UpdateUserTimezone → forwards ctx to NotificationService
- ResidenceService.CreateResidence → forwards ctx to SubscriptionService.CheckLimit
- NotificationService.registerAPNSDevice / registerGCMDevice → both take ctx
~75 method signatures, ~120 handler/test call sites updated. Tests pass
green; the only failure is the pre-existing flaky TaskHandler_QuickComplete
SQLite race that fails ~60% of runs on master.
Step 3 of the observability plan is now genuinely complete: every API
endpoint backed by a Go service emits a per-request flame graph with
HTTP → service → SQL spans, plus B2/APNs/FCM/asynq spans where applicable.

- Stripe integration: add StripeService with checkout sessions, customer
portal, and webhook handling for subscription lifecycle events.
- Free trials: auto-start configurable trial on first subscription check,
with admin-controllable duration and enable/disable toggle.
- Cross-platform guard: prevent duplicate subscriptions across iOS, Android,
and Stripe by checking existing platform before allowing purchase.
- Subscription model: add Stripe fields (customer_id, subscription_id,
price_id), trial fields (trial_start, trial_end, trial_used), and
SubscriptionSource/IsTrialActive helpers.
- API: add trial and source fields to status response, update OpenAPI spec.
- Clean up stale migration and audit docs.
