The desktop app could only queue while busy — `/steer` was in the palette
but had no first-class affordance, so the "nudge the agent mid-turn without
interrupting" lane was effectively unreachable.
Add a steer action to the composer: while busy with a text-only draft, a
steering-wheel button (and Cmd/Ctrl+Enter) injects the text into the live
turn via the `session.steer` RPC — the gateway folds it into the next tool
result so the model reads it on its next iteration. Plain Enter still queues.
steerPrompt returns false when the gateway has no live tool window (or the
RPC errors), and the composer re-queues the words so nothing is lost — the
same safety net as a plain queue.
* fix(desktop): make composer message queue reliable
The queue felt 'dumb' because of three real bugs:
1. Drained-after-interrupt sends went silent. cancelRun sets
interrupted:true and nothing reset it; submitPromptText's optimistic
seed preserved it, and the message stream drops every delta while
interrupted. So Send-now-while-busy and any interrupt+drain submitted
the next turn into a muted session. Fix: a fresh submit is a new turn —
seed interrupted:false.
2. Back-to-back queue drains stalled. The drain fires on the busy->false
settle edge, but busyRef (synced from the busy store by a separate
effect) can still read true on that same edge, so the drained send hit
the busy guard, returned false, and the entry was never removed. Fix:
fromQueue sends bypass the busyRef guard (the queue drain lock
serializes them); the user path keeps the guard.
3. Double-enter-to-interrupt killed single non-queue turns. The hidden
450ms timer meant a natural double-tap after sending stopped the agent.
Fix: empty Enter while busy is a no-op; interrupting is explicit —
Stop button or Esc.
Also: clean stop (no [interrupted] marker), Send-now works while busy
(promote + interrupt + auto-drain), settle on the interrupted completion
path. Adds regression tests and unblocks the prompt-actions suite by
completing its stale @/hermes mock.
* fix(desktop): float the queue panel as an overlay so the chat doesn't resize
The queue list rendered in-flow inside the composer root, so its height
fed --composer-measured-height (the composer rect drives the thread's
bottom padding + last-message clearance). Queuing a message grew that
rect and the whole chat visibly resized.
Anchor the panel out of flow above the composer (absolute bottom-full,
capped at 40vh with internal scroll). It no longer contributes to the
measured height, so the thread layout stays put and the list overlays the
(already faded) chat. Still collapsible via the panel's own
disclosure header.
* fix(desktop): queue panel collapsed by default + shared border with composer
- Default the queue disclosure to collapsed (compact 'N queued' pill)
instead of expanded.
- Drop the gap and merge the panel into the composer: square bottom
corners, no bottom border/radius, and overlap down by the Root's pt-2
(-mb-2) so the panel's borderless bottom lands on the composer surface's
top border — one continuous bordered shape.
* style(desktop): tighten queue panel padding
* style(desktop): trim queue-ux comments to house style
* style(desktop): drop 'Cursor' references from comments
The desktop `/title <name>` command 404s with "Session not found" on
every platform (reported on Windows in #38508).
Root cause: `session.create` returns two distinct ids — a *runtime*
session id (held in `activeSessionIdRef`) and a `stored_session_id` (the
DB `sessions.id`) — and deliberately does NOT persist a DB row until the
first turn. Routing `/title` through the REST `PATCH /api/sessions/{id}`
endpoint (as #38576 proposed) resolves the id against the `sessions`
table, so the runtime id — or any brand-new, not-yet-persisted session —
never resolves and returns 404. This is an id-type mismatch, not a
Windows file-locking quirk, so it fails on macOS and Linux too.
Fix: route `/title <name>` through the gateway's `session.title` RPC —
the exact path the TUI already uses (`ui-tui/.../slash/commands/core.ts`).
The RPC maps the runtime id to the in-memory session, writes through the
gateway's own DB connection, and queues the title (`pending: true`) when
the row isn't persisted yet, so it works for a fresh chat. The sidebar is
then refreshed via the existing `refreshSessions()` plumbing.
Keeps the sidebar-refresh wiring and `refreshSessions` threading from
#38576; replaces only the broken REST/slash-worker write path. A bare
`/title` (no arg) still falls through to the worker to show the current
title.
Tests rewritten to assert `session.title` routing with the runtime-vs-
stored id distinction (which the original mock collapsed), plus the
queued/`pending` fresh-chat case and the error path.
Supersedes #38576. Fixes#38508.
