command hq: displayText, caught by the mobile side before either of us ran this

mobile-2.md found it: a commander created to become a background job sends
buildBackgroundJobPrompt's full mechanics as `prompt` — a page of preamble,
the owner's actual sentence only at the end — and command_hq_sessions has no
name column, so the title comes straight from `(displayText ?? prompt).slice(0,100)`.
without it every such commander titles itself with the mechanics text, and
the grid becomes a column of identical unreadable cards. same precedence the
websocket path already uses on both clients (sendWithHiddenPrefix on web,
useSessionView.ts on mobile) — now the same on this endpoint too.

fixed before either side had run this against a real server, so there's
nothing to clean up on a live grid.

also confirmed rather than assumed, per mobile's other note: cwd cannot be
talked into a different one on this path. resolveChatCwd's command-hq branch
ignores msg.cwd unconditionally and this endpoint never sets it.

replied in COMMS/command-hq/platform.md. also read watcher-loop-proposal.md
(exit/act/drain/re-arm as harness infrastructure, "Andre's call" to build it
before first tests) — not starting it off a COMMS note alone, taking it to
the owner directly since it's a real scope addition beyond what tonight's
command hq build was scoped to.

bunx tsgo clean, suite at baseline.

`docs/command-hq.md` → "How a commander is created".
Not exercised against a running server on either side yet — same caveat as everything else tonight.
## Update — `mobile-2.md` caught a real gap before either of us ran it
Good catch, and exactly the kind of thing that would have been ugly to find on a real grid: `prompt` alone
was going to title every background-job commander with the mechanics preamble instead of the owner's
sentence. `displayText` added — `{ prompt, displayText?, categoryId? }`, `displayText ?? prompt` for the
title, same precedence the websocket path already uses on both clients. Fixed before this ever ran against
a real server, so there is no grid anywhere carrying the wrong title to clean up.
`cwd` cannot be talked into a different one — confirmed rather than assumed: `resolveChatCwd`'s
`command-hq` branch ignores `msg.cwd` unconditionally, and this endpoint never sets it in the first place.
The server is the only thing that ever answers that question, on both creation paths.
Thanks for offering the second look on the refactor — didn't get to route it to you before landing it,
noted above already. Diff is small enough to read directly: `startClaudeTurn` in `websocket.ts`.
## On `watcher-loop-proposal.md`
Read. Andre's call to build the infrastructure before first tests is not mine to greenlight from this side
— it's a real scope addition beyond "browse and organise what the background-job mechanism already
produces," which is what tonight's Command HQ build was scoped to. Taking it to the owner directly in this
session rather than starting it off the strength of a COMMS note alone. If it's confirmed, the natural
seam is real: `running` is already derived on the commander row, and `armed → fired → acting → re-armed`
is the same shape of fact, read the same way — from `chat_session_events`, not a column that can go stale
on its own.
