A plain blocklist for names like @support - separate from the collectible
system, so a reservation has no owner, no price and no "bought on Fragment"
badge.
- reserved_usernames table + migration.
- Enforced in replacePeerUsernameTx (the single editable-username write point:
account.updateUsername, channels.updateUsername, @BotFather /setusername) and
in the collectible mint path; a reserved name returns USERNAME_OCCUPIED.
- admin.Service: ReserveUsername / UnreserveUsername (journalled commands) and
the ReservedUsernames listing.
- adminapi: /v1/reserved-usernames{,/reserve,/unreserve}.
- telesrv-admin panel + a "Reserved Usernames" page in the web UI (dist rebuilt).
- Postgres and in-memory store implementations; the memory registry gains an
optional reserved-name check so tests exercise the same rule.
Keep bot credentials out of durable command results, fail bot deletion closed when session revocation fails, reject invalid scam/fake states at every write boundary, and make direct collectible grants a single replayable PostgreSQL aggregate.
Also lock admin gift sender/message limits and add regression coverage for rollback, replay, moderation constraints, and credential redaction.
Admin console additions (Layer 228):
- Give Gifts: dedicated tab with sorted Lottie/TGS gift picker + inline form; grant any catalog gift to a user/channel from 777000 (no charge)
- Upgraded/collectible delivery: mint a unique gift with admin-selected model/pattern/backdrop and custom number, or random/auto (DB FK + UNIQUE(gift_id,num) enforce invariants)
- SCAM/FAKE flags for users/channels (migration 0136) with configurable profile warning (TELESRV_SCAM_WARNING/TELESRV_FAKE_WARNING)
- Support toggle, force channel settings incl. gigagroup (migration 0137), username management, cosmetic color/emoji-status
- Emoji admin tab (custom emoji list + document IDs + Lottie/TGS preview)
- Bot management; soft UI / dark theme
Wired through Router -> admin.Service -> adminapi -> BFF -> React panel (en/zh/ru).
Sync telesrv 4c0e2d9 (feat: complete official star gift lifecycle and admin tooling).
Public adjustments: skipped private docs/deploy-nginx/README source changes, kept iamxvbaba/td public dependency, replaced local/private sample IP and orange seed label.
