Adds a narrower spam sanction alongside the existing account freeze: a
restricted account keeps every existing membership and conversation, but
cannot join new channels/groups (public join or invite link) and cannot
start a new conversation with a non-contact. Reachable both as a standalone
admin action and as a decision on a reported user's moderation case, with
the same idempotent-supersession and appeal wiring freeze already has.
UpdateUsernameAdmin already skipped the reserved-word check in the
availability lookup, but UserStore.UpdateUsername's own write path
(replacePeerUsernameTx / CollectibleUsernameStore.SetEditableUsername)
enforces the same operator blocklist a second time, independently and
unconditionally. That second check is what was still rejecting an admin
handing out a word they'd deliberately reserved, with "username occupied".
Add UpdateUsernameAdmin/SetEditableUsernameAdmin bypass variants down the
write path (postgres and memory) and route users.Service's actual write
through them when the availability check was already bypassed.
updateChannelParticipant carries the account's qts per the MTProto spec, but
the server always sent Qts: 0, so real clients silently discarded it as a
stale duplicate -- the banned/kicked user's channel never vanished locally
and no correct "removed by admin" message showed, even though the update was
delivered successfully at the transport layer.
Add a durable per-device qts queue (channel_participant_event_queue) sharing
its qts number space with the existing secret-chat queue (one qts sequence
per device, per spec), and use it to stamp a correct, monotonically
increasing qts on the update for every device of the affected user -- for
channel bans/kicks, admin promotion/demotion, and ownership transfer. A
device offline when it happened can now recover the event via
updates.getDifference instead of missing it permanently.
Add users.Service.UpdateUsernameAdmin, which skips the
config.ReservedUsernames block that self-service UpdateUsername enforces.
Operators need to be able to hand a reserved word to a specific account
even though regular users can't claim it themselves.
botFatherHelpText became a func() string during the rebase onto upstream
(matching upstream's own runtime-configurable-branding-safe pattern); two
call sites still referenced it as a bare value.

GetPassword minted a brand-new random SRP server secret and B on every call
while only ever assigning SRPID once (when zero). Two account.getPassword
calls in a row -- e.g. a settings screen refreshing state, then the transfer-
ownership dialog's own cloudPassword().reload() moments later -- silently
invalidated each other's B with no signal the client could detect (SRPID
unchanged), so a password check built from the first response's B failed
with PASSWORD_HASH_INVALID even though the typed password was correct.
The challenge now stays stable across reads and only rotates when it's
missing entirely; UpdatePasswordSettings/RecoverPassword already mint their
own fresh challenge whenever the password actually changes.

redisstore.userBaseValue has no Deleted/DeletedAt/Status field, so caching a
deleted user silently reset Deleted back to false (and Status to the zero
UserStatusUnknown) on every round trip. That never self-healed: each later
cache miss reloaded the correctly tombstoned DB row and immediately
re-corrupted it on write, so once anyone looked a deleted account up, it kept
showing a blank name with "last seen recently" instead of "Deleted Account".
Keep deleted users off the base cache entirely so lookups always hit the
authoritative store, and stop presence overlay from touching a Deleted user's
Status at all as defense in depth.

account.checkUsername / channels.checkUsername / bots.checkUsername said a
reserved name was available and only updateUsername rejected it. Add the
blocklist check to peerUsernameAvailable (covers account + channel, both
backends) and to bots.Service.CheckUsername, so the client shows "username is
taken" immediately.
The "Manage Bot" button on a bot's profile deep-links to @BotFather with
start=<bot username>. parseBotCommand dropped the argument, so /start <bot>
just replied with the generic greeting instead of the per-bot menu.
Route "/start <arg>" to the bot's "What do you want to do?" screen (same as
/mybots then tapping the bot) when <arg> names one of the sender's own bots by
username or id; empty or unknown args keep the greeting.
New supergroups are created with "chat history for new members" hidden (the
client sets this right after creation, matching official Telegram). The
official server then forces it back to visible when the group is made public;
owpengram's UpdateUsername left the flag alone, leaving public groups in a
state where non-members (and post-join members) see no history at all.
UpdateUsername now clears pre_history_hidden whenever a non-empty username is
assigned, in the same transaction, with a matching admin-log event. Removing
the username leaves the flag untouched, so the creator can hide history again
once the group is private.
cachedParticipants returned a participant page with Hash=0 whenever the
channel_base / channel_participants rows in read_model_versions were never
seeded for a channel (e.g. groups created via messages.createChat). With
Hash=0 the RPC layer can never answer channels.channelParticipantsNotModified,
so a client that polls the member list re-fetches it in a tight loop forever.
Fall back to a deterministic content hash derived from the page itself
(channel id, page key, count, and each member's id/role/status/rank) so an
unchanged member list yields an identical non-zero Hash and the client
converges. The read-model-backed path is unchanged.
- Edit Bot now shows the current value of every field (Name/About/
Description/Botpic/Commands) like BotFather, with real botpic status
via a new PeerHasAvatar port method.
- After editing a field the dialog lands back on a fresh Edit Bot menu
(working "Back to bot" / "Bots list" buttons) instead of ending, so a
follow-up button press no longer reports the button as expired.
- Service-bot messages now render @username as a tappable mention entity.
Button-driven bot management: paginated picker, per-bot API token /
revoke, Edit Bot (name/description/about/commands/botpic), Bot Settings
toggles (inline/groups/privacy), and delete. Navigation edits the menu
message in place via a new editServiceBotMessage helper.
Edit Botpic accepts a photo the user sends to @BotFather and sets it as
the bot's profile photo (new files.SetAvatarFromExistingPhoto, wired
through bots.SetBotUserpic / WithBotAvatarStore); photos.uploadProfilePhoto
does not accept a bot target so this is the only route.
