…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.

📝 WalkthroughWalkthroughChangesThe PR adds reusable Claude CLI sessions with mid-turn message steering. It exposes queueing capabilities, records steered transcript messages, updates the client UI, and propagates Ollama context-window metadata into the model catalog. Live Turn and Model Metadata
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR adds retained, steerable Claude sessions and mid-turn messaging, but unresolved lifecycle and race conditions can leave approval behavior unsafe, leak processes, or lose a user's draft; local-model context sizing also has a bounded collision issue.

Close the old broker before creating a new broker. The broker uses one socket path per thread. The persistent permission-proxy.ts connection remains usable after the path is unlinked, so reused turns do not inherently time out. The contract-change path still races: the old child’s close handler can close its broker after the new broker binds the same path and unlink the new broker’s socket.

The base-id key in contextWindowsFromPs is written unconditionally, and no test pins the collision case. Line 61 of server/drivers/local-inject.ts maps id.split(":")[0] to the current row's context_length for every row, so the last variant of a model family wins and a small model can inherit a large window.

Clear the unattended window when a user steers into a running turn.
The normal send path calls clearUnattended(bot.id) inside startTurn (Line 1023), because a person typing proves human presence. The steering branch returns at Line 2663 and never reaches startTurn, so the unattended flag survives.
If a webhook or routine started the turn, markUnattended is set (Line 1021). isUnattended then refreshes its own timestamp on every read (Line 508). A user who steers into that turn keeps it in unattended mode, so later tool approvals continue to resolve without a human card, for the whole rest of the turn.
Call clearUnattended before recording the steered message.
🛡️ Proposed fix
const steered = await instance.adapter.steer(busyBot.threadId, text).catch(() => false);
if (steered) {
+ // a person typing into the live turn ends the unattended window,
+ // exactly as a plain send does through startTurn
+ clearUnattended(busyBot.id);
store.appendMessage(busyBot.threadId, { role: "user", kind: "text", text, steered: true });
return json(res, 202, { ok: true, steered: true });

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Align the send control label with the steering placeholder.
The placeholder now tells the user that Enter sends into the running turn. The send button below still uses the queue wording while busy is true: aria-label is "Queue message" and title is "Queue — sends when the bot finishes" (Lines 397-398), and the icon is Clock (Line 404).
When canSteer is true, a screen-reader user hears the wrong action name for the button that performs the steering send. Branch those three values on canSteer as well.

In plain language
You can now talk to a Claude bot while it's working. Type while it's mid-task and press Enter: the message goes into the running turn — the bot sees it before its next step and adjusts, in the same reply. Before, the composer locked and your message waited until the bot finished (or was refused).

claude2.1.221 with--input-format stream-json: a turn ends withresultwhile stdin stays open (EOF is the exit signal, not the turn signal); a second user message on the same stdin starts a new turn in the same process; a message written mid-turn is delivered before the model's next call and folded into the same turn's singleresult(the reply ended "FINISHED MANGO" — MANGO was the mid-turn ask). That is precisely pi's steer semantics, provided natively.Changes
server/drivers/claude.ts— one live process per thread (sessions): reused when idle, the spawn contract is unchanged (args minus session/config-path specifics, MCP config content, cwd, model), and the harness'sresumeCursormatches; otherwise closed (stdin end → kill after 5s) and respawned with--resume.resultsettles the turn (turn.completed,activecleared) but keeps the process; idle close afterOMB_CLAUDE_SESSION_IDLE_MS(default 10 min, floor 10s).steer(threadId, text)writes into the open stdin; false when nothing is running. The permission broker is session-scoped; the MCP config file is deleted at first settle as before.server/contracts.ts—capabilities.queueing?: boolean; optionaladapter.steer?().

Default mode's event shape is unchanged so existing driver tests still pin the canonical sequence.Not in scope: Codex/ACP steering (separate spike — the plan's open question 2), a server-side follow-up queue (the composer's client-side one still covers non-queueing engines; on Claude a follow-up simply reuses the live process via
