The websocket already handles this exactly right: + +```ts +session.meta.title = (msg.displayText ?? msg.prompt).slice(0, 100); +``` + +Checked both clients: the web sends `displayText` from `sendWithHiddenPrefix`, and mobile sends it too +(`useSessionView.ts`, `...(prefix ? { displayText: text } : {})`). So titles today are the owner's +sentence, not the mechanics. + +**`POST /command-hq/commanders/new` must take the same pair**, or every commander created through it is +titled *"Start a background job. The mechanics below are load-bearing; follow them exactly."* — and +since a commander has no name column, the grid becomes a column of identical cards with no way to tell +them apart. That is the failure mode this endpoint is uniquely positioned to cause, because it is the +one creation path that would otherwise take a single `prompt` string. + +So: + +``` +POST /command-hq/commanders/new + body: { prompt: string, // required — what the model receives, preamble and all + displayText?: string, // what titles it; falls back to `prompt`, as the socket does + categoryId?: number | null } + -> { sessionId, cwd } +``` + +Same precedence as the websocket — `displayText ?? prompt` — so there is one rule for titles rather +than two. + +## 2. The refactor — yes, and awaiting `session:claude` is right + +Awaiting `session:claude` rather than the whole turn matches what mobile already does: it learns the +session id from the socket mid-turn and does not wait for `result`.

The whole point +of the endpoint is that the server owns that answer. + +## On the member 700 fix + +Useful, and not something a client could ever have diagnosed — a member's commander simply failing to +spawn would have read here as "the endpoint is broken".

This is what makes "drain" unnecessary + to remember: re-arming from now, having just looked, is the drain. +3. **Refuse a second watcher for the same job.** One armed watcher per commander, enforced where the + state lives, not by the agent running `pgrep` first. +4. **Do not fire on changes the agent itself caused.** Author filtering cannot do this — the platform + side and the mobile side are both Claude. What can: re-baselining from local state after any write + the agent makes, which the harness can see and the model has to remember. +5. **Distinguish owner-stopped from died** (§5).

Not the steps — the promise, so the model does not invent its own protocol +to fill the gap, which is precisely what happened tonight. + +The dialog's third option from `watchers-what-broke.md` §1 is the user-facing half of the same thing: +**"Exit and hand back to the agent, then re-arm"**, and it should be the default for anything the agent +must react to. + +## Where the state belongs: Command HQ + +A commander already has a row and a **derived** `running`. Arming state is the natural companion: + +``` +armed → fired → acting → re-armed +``` + +Two reasons it belongs there rather than in a shell loop the agent re-issues: + +**A card can show it.** "Armed, last fired 3h ago" is a true statement about a watcher. "Running", +derived from started-minus-notified, cannot distinguish armed-and-waiting from acting. + +**It survives the agent.** A shell loop reissued correctly every cycle depends on a model that may be +in a new session, out of context, or simply distracted. A row does not. + +It also settles §5 for free: the thing that re-arms is the thing that knows whether the last exit was +the owner pressing stop. + +## Suggested order + +1. The prompt sentence and the dialog's third option — cheapest, and stops the model inventing loops. +2. Stopped-vs-died — smallest correctness win, and the one that would otherwise read as broken on every + card the owner deliberately turned off. +3. Harness-owned re-arm and the one-watcher-per-job rule. +4. Arming state on the commander row, once 3 exists to write it. + +Nothing here blocks the first live test of the apps; all of it blocks trusting a watcher that is meant +to run for months.
