…ss per session
Verified against claude 2.1.221 with --input-format stream-json: the CLI
settles a turn with `result` while stdin stays OPEN (EOF is the exit
signal, not the turn signal); the next user message on the same stdin is
a new turn in the same process; a message that arrives MID-turn is
delivered before the model's next call and folded into the same turn's
one result. That last behaviour is exactly the "steer" the plan wanted.
- claude.ts keeps one live process per thread across turns: reused while
idle, unchanged in spawn contract, and the session the harness wants;
otherwise closed and respawned with --resume. `result` settles the
turn, not the process; the process closes after 10 minutes idle
(OMB_CLAUDE_SESSION_IDLE_MS). steer() writes into the open stdin.
- contract: capabilities.queueing and an optional adapter.steer() — the
one-file driver promise holds; every other driver keeps the 409.
- harness: POST /messages while busy on a queueing engine steers instead
of 409ing; the message is appended in order and marked `steered`. The
composer stays open on such engines ("Enter sends this into the running
turn"); a "sent mid-turn" tag on the bubble says the model saw it.
- 3.1 remainder: injected local models carry contextWindow from Ollama's
/api/ps context_length when the model is running, so a small model's
rebuild is sized to what it can hold instead of a name-based guess.
- fake claude rewritten line-driven (steer folding, `slow` mode).
Items 3.2 (and the 3.1 remainder) of docs/plans/agent-harness-upgrades-v2.md.
Answers the plan's open question 3.

…iver main already reaches local models by INJECTING them into the installed agent CLIs (Claude Code, Codex, ACP agents pointed at Ollama et al.) — the right route when a CLI is present, since it keeps tools, approvals and the computer. What it cannot do is run anything on a machine with only Ollama or LM Studio and no CLI at all. This is that path. - server/drivers/local.ts, factored from grok.ts: an OpenAI-shaped SSE client spoken to directly, transcript-replay (the harness's rebuild feeds it), generateText, `system` role (not `developer`), a bearer on keyless hosts (some hide their models without one). Hosts come from LOCAL_HOSTS (Ollama, LM Studio, oMLX, EXO, Unsloth) or a custom URL. - catalog from the HOST: /v1/models is what is pulled, /api/ps (Ollama) is what is running — running first and flagged — with each running model's real context window; refreshModels() re-probes live. - detection in the CLI engines' vocabulary: nothing listening → unavailable with "Ollama isn't running — start it with `ollama serve`", ProviderSnapshot.notRunning, and the setup card offers "Start Ollama" (signInCommand) instead of an install; brew/curl install commands when it is not installed at all. - capabilities honest: no MCP, no asks, no computer, no live session — a chat bot. Registered in builtIn.ts and shipped into existing fleets as `local` (Ollama) the way Qwen/Hermes were. Item 3.1 of docs/plans/agent-harness-upgrades-v2.md, rescoped to what main's injection does not cover. Stacked on #219 (uses its contextWindowsFromPs and capabilities.queueing).

🎯 Functional Correctness | 🔴 Critical | 🏗️ Heavy lift
The provisional broker destroys the live session's permission socket.
permissionSocketPath(threadId) depends only on threadId (lines 194-197), so every turn on a thread builds its broker on the same socket path. In acceptEdits mode the code creates the broker at line 482 before it knows the session will be reused. createPermissionBroker unlinks the existing socket file and listens on the same path (lines 210-212, 259). The live session's broker then has no socket file, and broker?.close() at line 545 unlinks the path again. After the first follow-up turn on a reused session, the CLI's permission proxy cannot connect, every ask times out, and approvals become silent denials. The same collision applies on the respawn path: the old session's close handler calls session.broker?.close() at line 699 and unlinks the socket the new session already listens on.
Create the broker only on the spawn path, or make the socket path unique per session and keep the session's own broker untouched.

turn.completed carries a field the contract does not declare.
RuntimeEvent for turn.completed declares ok, stopReason, cost, and denials only (server/contracts.ts lines 88-94). The spread adds usage, so TypeScript does not reject it, but typed consumers cannot read it. server/drivers/local.test.ts line 99 asserts on that field, which locks the test to an undeclared shape. Either declare usage on turn.completed in server/contracts.ts, or drop it here and rely on the thread.token-usage.updated event emitted on line 252.

Align steering eligibility with the active turn.
bot.busy does not prove that busyBot.threadId owns the active provider turn. A room turn marks its member busy but runs on the room thread, so this call attempts to steer a nonexistent personal-thread session. Also, steer() can reject after the provider turn settles while busy is still true. The fallback then calls startTurn(), which rejects with 409 because the store has not folded completion yet.
server/index.ts#L2656-L2669: identify the active turn thread before steering. Do not steer a personal-thread message into a room turn.

A bot can now run on a local model with nothing else installed — no Claude Code, no Codex, no account. Just Ollama (or LM Studio / oMLX / EXO / Unsloth) running on the machine.
ollama serveand a "Start in Terminal" button — not an install card. Once it's up, the models you've pulled appear, running ones first and flagged, and you pick one like any other model.Why this shape
mainalready covers local models by injecting them into installed agent CLIs (#174/#177): the better route when a CLI exists. The plan's 3.1 "done when" — a bot runs on a locally pulled model with no cloud credentials configured anywhere — still failed on a CLI-less machine.
