What

STOPGAP, to be deleted once agents' typing pulses reach the relay (#792 plus block/buzz#8207). While an Agents2 agent works on a mention (the same lifetime as #860's reactions, Agents2Service.working()), this device shows the agent typing in the mention's thread. Nothing is published, so other devices don't see it.

• agents2/local-typing.ts builds a kind 20002 pulse every 3 s. It uses the tags feat(agents2): show agents as typing while they work on a mention #792 would publish: h, the thread root, and the mention as reply.
• The new typing.local(event) in relay/typing.ts feeds that pulse into the session's existing typing store as if it came live. The store's expiry (8 s), the end-on-reply rule (the agent's kind 9 hides the indicator, then a 2 s quiet period) and the existing indicators all work unchanged.
• The session is the same per-community session the UI uses (communities.open → acquire). Agents2 agents are already in agentChoices through localAgents.bind(agents2.local), so the floating indicator and the thread rows show them.
• No FOUNDATION file changes: relay/session.ts already exposes typing.capability.

Removal

Every piece is tagged STOPGAP(agent-local-typing). Run grep -rn "STOPGAP(agent-local-typing)" src and delete what it marks. #860's reactions are tagged STOPGAP(agent-working-reactions) the same way.

Notes

• When the turn settles, the host feeds a local kind 9 end, so the indicator clears at once instead of when the last pulse expires (up to 8 s). Codex makes one more model call after a final send, so its indicator can stay about 3 s past its reply.
• The agent's own posts in that thread (progress updates) don't hide it, so it doesn't blink off for 2–5 s after each one. Only the local end does.
• A failed pulse warns once, then stops pulsing; it never breaks the run.
• typing.local sits on the session's typing capability, so code that can see the session could show fake typing for any pubkey. It only affects this device.

Validation

• vitest run across agents2, relay typing and activity-typing, Codex, Claude Code and TypingIndicator: 22 files / 244 tests pass. tsc --noEmit is clean.
• New tests:
  • a local pulse shows like a live one and the agent's reply ends it
  • pulses come every 3 s in the mention's thread and stop when told to
  • a pulse is skipped while the community is not ready
  • a throwing pulse stops the pulses
  • the service starts typing for a mention run
  • stopping ends the indicator at once, and a local end hides it like a reply
• Not yet done: a re-test after baxen's first test (which found the 8 s tail, now fixed).

🤖 Folded into #860 (show agents working): local typing now lives there with the 👀💬 reactions and the Codex settle fix from #863. Branch kept.
