-// Command createuser inserts a users row with an operator-chosen id, bypassing
-// the normal users_id_seq auto-assignment. This works because users.id is
-// GENERATED BY DEFAULT AS IDENTITY (not GENERATED ALWAYS) -- an explicit id in
-// the INSERT is honored, the same mechanism ensureOfficialSystemUserWithDB
-// (internal/store/postgres/message_send.go) already relies on to seed the
-// built-in system accounts (ChatBot, BotFather, ...) at their fixed ids.
-//
-// Normal signup (auth.signUp) never lets a caller pick an id, so this exists
-// purely for local/dev tooling -- reserving a specific low id (below
-// OfficialSystemUserID=777000, say) for a test account.
-//
-// Usage:
-//
-//	createuser -id 1000 [-first-name Test] [-last-name User] [-username testuser] -phone "15550001234"
-//	createuser -id 1000 [-first-name Test] [-last-name User] [-username testuser] -email "test@example.com"
-//
-// -phone and -email are mutually exclusive: an email-signup account never
-// stores the address in users.phone directly (see internal/domain/emailphone.go)
-// -- it gets a synthetic "888"-prefixed display phone instead (the same one
-// assignEmailSignupDisplayPhone hands a real email-signup account), with the
-// real address recorded separately in signup_email.

-# OwpenGram Server vs. Telegram - Feature Comparison
-
-This document compares what OwpenGram Server actually implements against the
-behaviour of Telegram's official server, as seen through the MTProto API
-(layer 228) and the official clients (Telegram Desktop is the primary target,
-with Android / iOS / Web compatibility paths).
-
-It is written from the server code in this repository: ~633 canonical
-`registerRPC` handlers across `internal/rpc`, plus the domain services in
-`internal/app/*`. "Telegram" below means the closed official backend.
-
-Legend:
-
-- **Full** - implemented with real server-side state and semantics
-- **Partial** - core paths work; edges, scale features, or moderation depth missing
-- **Stub** - RPC is answered with a fixed/empty valid response so clients don't
-  hang or crash, but there is no feature behind it
-- **None** - not registered / not implemented
-

-## Summary
-
-**Strong, near-complete parity:**
-
-- MTProto edge, auth, sessions, PFS, 2FA/SRP
-- Private chat messaging: send/edit/delete/forward/reply/reactions/scheduled/
-  drafts/search/translation/albums/rich text
-- Groups, supergroups, channels: admin model, invite links, forum topics,
-  discussion groups, slow mode, anti-spam toggles, public search
-- Media pipeline with pluggable local-disk or S3 storage
-- Stickers / custom emoji / GIFs (with an extended `@gif` catalog)
-- Bots, inline mode, web apps / mini apps, games
-- Stories (incl. layer 228 albums, stealth mode)
-- Secret chats (E2E, server as blind relay)
-- Dialogs/folders/chatlists and the full update-difference sync machinery
-- Themes, wallpapers, peer colors, language packs
-
-**Partial / compatibility-first:**
-
-- Calls and live streams: signaling and state are complete; media relay needs
-  an operator-run SFU/TURN
-- Boosts, channel/story statistics, communities, business features, conference
-  calls: core flows present, some perks and edges not gated
-- Bot API HTTP gateway: a useful subset, not the full `api.telegram.org`
-- Moderation: instance-level tooling exists, no global trust-and-safety network
-
-**Deliberately not implemented:**
-
-- The entire payments/economy layer: invoices, Telegram Stars, star gifts,
-  Premium purchase, TON/revenue withdrawal, Play/App Store billing. Read-only
-  RPCs return valid empty responses so clients don't break.
