The +freeq.at/* Tag Registry¶

Everything freeq adds to IRC rides IRCv3 message
tags. This page is the
canonical registry of the vendored +freeq.at/* namespace, plus the
standard/draft tags freeq implements. A tag-unaware client ignores all of
them and still sees readable text — that is the design contract.

Tags prefixed + are client-only tags (relayed verbatim by the server);
values are strings per the IRCv3 escaping rules.

Identity & integrity¶

Tag	On	Meaning
+freeq.at/sig	PRIVMSG, TAGMSG	Per-session ed25519 signature: ed25519:<kid>:<base64url sig>. For act messages it covers the JCS-canonicalized act-* tags; for plain messages, the message body. Public keys: /api/v1/signing-keys/<did>.
+freeq.at/account	PRIVMSG (server → client)	The sender's authenticated DID, attached by the server.
+freeq.at/origin	relayed messages	Origin server name for messages arriving via federation. Clients show "via {origin}" and suppress local verification badges.
+freeq.at/echo-nonce	PRIVMSG (client → server)	Client-chosen nonce echoed back with the server-assigned msgid, so senders can match their own echo-message.

Messaging features¶

Tag	On	Meaning
+draft/edit=<msgid>	PRIVMSG	This message replaces <msgid>. Server verifies authorship.
+draft/delete=<msgid>	TAGMSG	Soft-delete <msgid> (author or ops).
+draft/reply=<msgid> / +reply	PRIVMSG, TAGMSG	Threading / reply-to reference.
+draft/react / +react + +reply=<msgid>	TAGMSG	Add a reaction; +freeq.at/unreact removes one.
+typing=active\|done	TAGMSG	Typing indicator.
+freeq.at/reactions	CHATHISTORY replay	Server-persisted reaction tallies, so reactions survive reconnects.
+freeq.at/pin / +freeq.at/unpin	TAGMSG	Pin/unpin a message in a channel.
+freeq.at/streaming	PRIVMSG	Marks an in-progress streamed message (agents editing as they generate).
+freeq.at/multiline	PRIVMSG	Legacy multi-line encoding; new senders use standard draft/multiline BATCHes.

Agent coordination¶

Tag	On	Meaning
+freeq.at/event	PRIVMSG	Typed coordination event: task_request, task_update, task_complete, …
+freeq.at/task-id	PRIVMSG	The task this event belongs to.
+freeq.at/payload	PRIVMSG	JSON payload for the event (machine-readable half of the message).
+freeq.at/parent, +freeq.at/ref	PRIVMSG	Event lineage / cross-references (delegation, evidence links).
+freeq.at/evidence-type	PRIVMSG	Kind of evidence attached to a task event.
+freeq.at/actor-class	messages	Declares the sender class (e.g. agent vs human) for client rendering.

Signed action cards (act)¶

The handoff/action system — signed, structured "cards" (see the act RFC in
the repo). The signature in +freeq.at/sig covers every act-* tag,
JCS-canonicalized; byte-compatible across the Rust and TypeScript SDKs with
shared test vectors (spec/act-signing-vectors.json).

Tag	Meaning
+freeq.at/act	Card type/version.
+freeq.at/act-id	Stable card id.
+freeq.at/act-verb	What is being asked/done.
+freeq.at/act-title	Human-readable title.
+freeq.at/act-from	Originating actor.

Governance & budgets¶

Tag	Meaning
+freeq.at/governance	Governance verb events (pause / resume / revoke / approve).
+freeq.at/reason	Human-readable reason attached to a governance action.
+freeq.at/issued-by	Who issued a capability/credential.
+freeq.at/limit, +freeq.at/spent, +freeq.at/unit	Budgeted capabilities: spending caps for economic controls.

Voice / video (AV sessions)¶

Control plane for calls — see the AV protocol for the
full lifecycle. Media itself rides MoQ over QUIC, never IRC.

Tag	Direction	Meaning
+freeq.at/av-start	client → server	Open a call in this channel.
+freeq.at/av-join / +freeq.at/av-leave	client → server	Join / leave the call in av-id.
+freeq.at/av-end	client → server	End the call (originator/ops).
+freeq.at/av-id	both	Call identifier.
+freeq.at/av-instance	both	Per-device instance id (multi-device: your phone and laptop are distinct participants).
+freeq.at/av-state	server → channel	Broadcast call state (started, ended, participant changes).
+freeq.at/av-participants	server → channel	Current participant list.
+freeq.at/av-actor	server → channel	Who performed the state change.
+freeq.at/av-title	both	Optional call title.
+freeq.at/av-token	server → client	Media-plane auth token for the SFU.
