ADMIN_USER_IDS (Telegram:AdminUserIds) takes a comma separated list; the older
ADMIN_USER_ID / Telegram:AdminUserId still works, also takes a list and is merged.
Empty entries and duplicates are ignored, non-numeric entries fail validation.
Impersonation is now per admin: one admin per target, an impersonating admin
can't be impersonated, and every admin's chat menu lists /impersonate.
Streamable HTTP/SSE servers from the workspace's .volcanic/mcp/servers.json.
Headers are sealed with AES-GCM; the chat and the visible fields are the
associated data, so only /mcp_add|remove|tools change servers. Tools
<server>__<tool> go live in the session. An unreachable server is skipped
and reported in the system prompt. Keys are redacted from tool results, and
Telegram deletes messages that carry one.
OpenAI gpt-4o-mini-tts (female voice nova by default; TTS_MODEL/TTS_VOICE) renders OGG/Opus,
sent with sendVoice in order with rendered output. Up to 4500 characters per call, split
into 1500-character parts at paragraph/sentence/word boundaries; all parts are synthesized
before any is sent, and API errors come back to the agent as text with the key hidden.
On whenever OPENAI_API_KEY is set.
While on, the admin's updates are routed as the target user's (allow-list,
chat, workspace, session, settings, jobs) and the target chat's output goes
to the admin's chat. The target's own updates are dropped with a notice that
an admin is working with their account. In memory; /impersonate 0 stops.
ChatRegistry -> JobScheduler -> IScriptEnvironment -> ChatRegistry made the host
fail at startup. CalendarScriptEnvironment now takes TelegramOptions and computes
the workspace with the new static ChatRegistry.WorkspaceFor(options, chatId).
- JobScheduler: a stored job whose zone lookup throws no longer fails StartAsync; timer re-armed under the lock;
a delivery cut off by shutdown isn't recorded (one-offs fire again after restart); CancelJobAsync in one step
- Schedules.ParseAt: ISO 8601 with a date only (no machine-clock date for a bare 09:00)
- core: a FollowUp prompt that loses the race to a starting run joins it as a follow-up, not steering
- Telegram: TimeZoneFor tolerates non-numeric targets; RunPromptAsync waits only when queued; one agent dir
- ScriptRunner: bad workspace paths are Failed, not exceptions; zone id helpers share TimeZoneIds.ToIana's rule
- tests: no wall-clock sleeps in scheduler tests; transcript-entry, disabled-scheduler and failing-prompt coverage
- docs: spec notes for the above; README row for the scheduler
ChatSettingsStore keeps each chat's IANA zone in <AgentDir>/telegram/chat-settings.json;
ChatTimeZoneService is the one path for a change (store, live session, scheduler re-evaluation,
reply text). ChatRegistry.TimeZoneFor now reads the store and new sessions start in the chat's zone.
/timezone, the set_timezone tool (ChatSettingsExtension), /status zone line, DEFAULT_TIMEZONE.
The store updates its cache under the write gate so the last file written is the newest state.
Add TelegramLimits, TelegramChatChannel (every delivery through
ChatRenderer.RunInOrderAsync, auto photo falls back to a document on a 400)
and wire it into ChatRegistry as AgentSessionOptions.Channel and
ChatContext.Channel. Spec: SendTextAsync names its failure text
("Telegram did not accept the message.") and throws when any chunk fails.
A flushed batch that joins a running request gets a ๐ reaction on each message. /new and a successful /resume drop buffered and in-flight inbox parts. A forwarded message never answers a pending TelegramUi question. /help mentions replies and quotes.
Spec: unhandled /commands bypass the inbox verbatim; the header zone comes from ChatRegistry.TimeZoneFor (session zone until ChatSettingsStore); only text and photos until the attachments spec.
