# Phase 9 — User, Profile, and Dashboard Report

## Result

Phase 9 is complete. The running web application now exposes authenticated bootstrap, dashboard, and profile APIs plus permission-protected, read-only Admin user inspection.

## Delivered

1. Public settings, managed links, feature flags, currency, theme, and maintenance repositories/services.
2. Redis-backed fail-open caching with strict payload and TTL bounds.
3. Safe bootstrap aggregation for app configuration, current user, restrictions, maintenance, and unread counts.
4. Dashboard aggregation for ledger-derived balance projections, daily task progress, recent available-account transactions, task previews, referrals, and free-only reward availability.
5. DST-aware local-day and Monday-start local-week conversion into UTC database bounds.
6. User profile read/update with Telegram-owned fields made immutable to the user.
7. Transactional preference updates, row locking, feature gating, server validation, and privacy-minimized activity records.
8. Admin user list/detail services with `users.view`, network policy, parameterized filters, public IDs, and audit context.
9. Maintenance routing that preserves health, auth, bootstrap, and the exact configured Telegram webhook while respecting Admin access policy.
10. Closed-schema theme-token validation and deployment-owned URL allowlisting.

## Security invariants

- A request body cannot set Telegram identity, name, username, status, balance, reward, permissions, or internal IDs.
- Dashboard amounts and large counts remain decimal strings; no floating-point financial arithmetic is used.
- Dashboard balance is read from a server-side projection and never accepted from the client.
- Task previews omit destination URLs; Phase 11 will perform eligibility checks before disclosing a start destination.
- The free-reward preview reads only database rows constrained to zero cost and no purchase requirement. Phase 9 has no claim endpoint and no paid chance mechanism.
- Feature-flag rules not yet supported by the Phase 15 rule engine fail closed.
- Malformed cache, setting, timezone, URL, or theme values cannot weaken authorization or inject arbitrary CSS/URLs.
- User routes use route-scoped authentication so their `/api/v1` mount cannot intercept Admin namespaces.

## Verification

The Phase 9 suite covers cache failures, DST transitions, datetime normalization, theme sanitization, setting guards, profile field ownership, transaction ordering, feature gates, large integer serialization, free-reward frequency preview, Admin pagination/mapping, SQL parameterization, CSRF, authentication, RBAC, maintenance routing, and webhook reachability.

The complete release gate passed with 146 tests, lint, formatting, environment-template validation, database-schema validation, CSS compilation, and the 238-file project manifest. The lockfile-backed offline production dependency audit reported zero known vulnerabilities, and the source secret-pattern scan found no release credential.

No live MySQL database, Telegram account, Admin account, Redis deployment, or external service was modified while building Phase 9.

**Phase 9 status: COMPLETE AND VERIFIED.**
