* feat(channels): custom emoji discovery via emoji-list across Discord, Slack, Telegram
Make custom emojis discoverable by the agent. The message tool's emoji
param now documents custom-emoji syntax per channel (gate-aware, only
naming emoji-list when the action is actually advertised). Discord
emoji-list defaults guildId from the current conversation and returns
reaction-ready { name, identifier, animated? } entries; Slack returns
normalized shortcodes with aliasOf. Telegram gains emoji-list backed by
one canonical allowed-reactions owner (getChat available_reactions,
custom_emoji entries preserved), numeric custom-emoji reactions, and
replaces the dead 'reaction disallow list' error advice with a bounded
sample of the chat's allowed reactions.
* test(channels): expect telegram emoji-list provider-owned read gate in plugin shape contract
* test(telegram): prove emoji-list authority chain via mock-gateway e2e
Ephemeral gateway + mock Bot API + mock OpenAI provider: current-chat
emoji-list returns normalized standard and custom_emoji identifiers with
exactly one getChat call; a delegated cross-chat request is rejected with
the conversation-binding error and zero Bot API requests reference the
foreign chat.
Centralize untrusted audio transcript framing across channel plugins and keep Discord voice transcripts out of typed command provenance.

* feat(gateway): proxy channel conversation avatars
* feat(discord): capture conversation avatars
* feat(slack): capture DM sender avatars
* test(discord): bind guild avatar mock
* feat(ui): render channel conversation avatars
* fix(ui): align sidebar owner fixtures
* fix(gateway): version channel-avatar routes by media revision
A stable per-session URL let AuthenticatedAvatarRouteLoader's blob and
sticky-404 caches pin a mounted row to a stale or blank avatar after the
backing media changed. Append an opaque digest of the media reference so
replacement and 404-recovery change the route identity.
* test(ui): align sidebar owner facet
* fix(ui): keep owner chip until channel avatar loads
A session with a channelAvatarUrl suppressed its owner chip even while the
blob was loading, auth was not ready, or the route 404ed, leaving an empty
lead slot. The chip now rides as fallback content inside the avatar element
and yields only to a usable image. Covers 404 and auth-pending states;
avatar rows keep renderedOwnerId unset so an owner-viewer stays visible in
the facepile.
* perf(ui): keep channel avatar fallback within budget
* perf(ui): lazy-load the channel avatar element
The avatar element and its authenticated blob loader rode the startup
bundle through session-leading-indicator, pushing startup JS 51 B over the
CI gzip budget. Channel avatars are not startup-critical: register the
element on the first avatar row; the owner-chip fallback covers the
one-time upgrade window. Startup JS returns ~1 KiB under the ceiling.
* build(ui): raise startup baseline for channel avatars
CI-measured startup JS is 344379 B against a 343289 B baseline (+1090 B).
The avatar element and blob loader are code-split out of startup (previous
commit); the residual is the sidebar lead-slot render branch and row
plumbing, which cannot be deferred. Baseline updated via
check-control-ui-performance --update-baseline with CI bytes per the
script's contract; well inside the 4096 B ratchet step and 358400 B
ceiling.
Slack appends task_update details/output per update for the same id (only title/status replace); the native progress stream re-sent every row each snapshot, so bash rows accumulated "completedcompleted…". Reconcile now emits only changed rows with append-only field deltas, keeps status words out of details, and puts the once-emitted result (file delta or failing exit) in output.
The finished-turn digest ('🧠 N thoughts · 💬 N notes · 🛠️ N tool calls ·
⏱️ Ns') was synthesized onto three surfaces: Slack's Block Kit card footer
(removed in #123851), Discord's final-answer subtext, and a duplicate Telegram
implementation added to match Discord.
Nothing gated it — no config key for the receipt has ever existed on any
channel — so PR #122976, which deleted it from Slack's native progress surface,
could only ever be a partial removal. Finish it: live progress surfaces keep
their in-flight indicators, and a finished turn leaves the answer with nothing
synthesized appended.
Telegram's window collapsed *into* the digest, so it now retires like every
other surface; Discord already discarded its draft after the final landed. The
core tracker keeps only the live counters Slack's working footer reads.
The Block Kit session card terminalized into a '🛠️ N tool calls · ⏱️ Ns'
footer, leaving a per-turn receipt in the Slack transcript on the default
progress path. PR #122976 deleted the same receipt from the native progress
surface but left this sibling rendering it.
Finished cards now keep only the durable diff stat and the session link;
tool-call and elapsed counters stay live working state. Also corrects the
documented channels.slack.streaming.mode default, stale since #122552.
