# Launch feature verification — September 4, 2026

| Feature | Implementation and verification |
| --- | --- |
| Historical check-ins | Calendar selection and date picker open dated count, checkbox, and task controls. Integration coverage changes a habit's method and corrects yesterday without changing today. Browser verified a saved historical count and refreshed calendar. |
| Account settings | Timezone changes refresh the dashboard; JSON exports include owned records without session credentials. Typed-confirmation deletion removes dependent records and revokes sessions. API tests cover ownership, Origin checks, confirmation, foreign keys, and another account remaining intact. Browser verified timezone persistence. |
| Discord sharing controls | SQLite reservations enforce one new post per user per minute and ten per channel per minute; duplicate checks remain safe. Tests cover cooldowns, channel quotas, allowlists, and rejected/uncertain delivery behavior. |
| Backup and recovery | Production snapshots, pre-migration snapshot, retention, optional replica directory, and fresh-path recovery. Tests restore committed WAL progress, revoke sessions, disable recovered reminders, verify replicas and retention, reject unavailable storage and existing destinations, and execute both CLIs. |
| Monitoring | Request IDs and sanitized structured error events; database/backup-aware health; independent monitor with sustained-failure and recovery transitions. Tests exercise a closed database and live HTTP probes; one-shot CLI passed against the disposable server. |
| Archive and restore | Dashboard archive action, history view, and restore. Integration and browser checks confirm a restored habit returns to today's dashboard while earlier completion remains intact. |
| Daily reminders | Opt-in settings, timezone/quiet hours, unfinished-only private messages, persistent daily reservations, rate-limit deferral, and delivery status. Tests cover concurrent workers, DST fall-back, opt-out during channel creation, uncertain sends, ownership, export, and deletion. Browser saved the selected time, delivered one message through the local stub, showed Delivered, and saved opt-out. |

Validation commands: `bun run typecheck`, `bun test`, `bun run test:smoke`, and
`git diff --check`. Browser checks used the in-memory preview on port 3107 and
verified desktop and narrow layouts (480px minimum layout viewport available in
the in-app browser), with no page-level horizontal overflow in settings.

Live Discord messages, production account deletion, and deployment were not
performed. Set the production origin, bot credentials/permissions, any sharing
allowlist, durable backup volume/replica, and independent monitor/log collection
when deploying. Off-machine storage and an external alert destination must be
provided by the deployment environment; their provisioning is outside the app.
