v0.11.0 — drag-to-split, Worker channel cards, a composer that gets out of the way

[ojowwalker77]

Minor release. Six strands, kept in one commit because ChatView sits in the middle of most of them and a path-based split would have been arbitrary.

Worker channel card

A cross-Worker request rendered its raw protocol prompt straight into the transcript — channel id, tool instructions, "never edit the requesting Worker's repository". That is model-facing text.

It is now a card: subject, peer Worker, live status, the ask, replies, and controls to open the peer Thread or close the channel. Channel traffic is recognised by the message id the reactor already minted (moved to packages/shared so both ends share one scheme) rather than by dispatchOrigin: "automation", which would also have swallowed scheduled automations.

Card status is deliberately not Task status. A Task is in_progress from the moment the responder session starts, but the reader wants to know whether an answer actually came back — so the card computes waiting / answered / closed separately.

Drag-to-split

Drag a Thread from the sidebar onto a pane. Outer thirds split, middle replaces.

Panes form a tree, not a list. A list has one axis, so splitting a pane inside a column had to reorient every other pane — which is exactly the bug the first attempt shipped. Each branch owns its axis and divides evenly at every depth. Same-axis drops join the existing branch instead of nesting, which is what keeps siblings equal rather than handing the new pane half of one sibling's space. Structure collapses on removal, so repeated split/close leaves no invisible single-child branches still dividing the space.

Splits persist across reloads, keyed by the Thread that owns the route, and prune when their Threads are deleted so a persisted split cannot resurrect a deleted Thread as an empty pane.

Composer

⌘J collapses it into a provider-icon button, taking its gutter and the branch row with it — the transcript gets the whole pane. The composer footer carries a collapse control too, since a shortcut advertises nothing. Both refuse while a turn is running or a prompt is waiting.

It now floats rather than sitting in flow. As a flex sibling it took height off the content region, which cut scrolling surfaces short and clipped the research document at its top edge.

Model and effort pickers moved into the branch bar — Model, Effort, Local, Branch — and the overflow tiering that already existed for the footer follows them: it measures the bar now, so a narrow pane drops the effort label, then the model name, leaving the provider icon. The branch label ellipsises instead of clipping. Local/Worktree disappears once the Thread has its first message and the environment stops being changeable.

Sidebar edge peek

Arc-style, ported from phibrowser-mac after asking that Worker through the inbox channel this release also improves. A 10px edge strip armed 350ms after collapse, opening immediately, closing on a 120ms delay with a 500ms floor. Hover is re-sampled when the timer fires rather than trusted from the leave event — a panel appearing under a stationary cursor never emits an enter. Peeked, the sidebar paints an opaque surface; docked it is deliberately transparent over the shell canvas, which let the header read straight through it.

Departures from the source: the app's shared 220ms disclosure timing instead of 150ms, prefers-reduced-motion handling it lacks, and window blur/visibility dismissal in place of its AppKit occlusion observer.

Settings regrouped

General was a dumping ground of eight unrelated groups, while shortcuts, worktrees and archived Threads hid under Advanced and permissions was split across two places.

Eleven sections in four nav groups now, using grouping the nav component already supported. Every retired section id still resolves, so existing deep links keep working. Eleven dead search entries pointing at rows that no longer render are gone, along with one stale title whose anchor never resolved — and Profile, previously unreachable from settings search, has entries. A guard test asserts every section has searchable rows, which is how the Profile gap surfaced.

File tagging removed from @

Agents read the repository themselves. Workers, Tasks and plugins stay — only file and folder paths go, along with the @local folder browser. Existing @path chips still render, so old Threads are unchanged; only authoring is gone.

Fixes

Stuck sidebar resize (pre-existing): the drag ended only via React handlers on the rail, so a lost pointer capture, a re-render, or a release outside the window left it running — the ref stayed set, the body kept col-resize, and the next pointer move resized again. It now ends from window listeners including lostpointercapture and blur, with unmount cleanup.

Split-pane close button was unclickable: it floated over the chat header, whose -webkit-app-region: drag makes macOS swallow clicks for anything painted inside it regardless of z-index. Adding no-drag to the overlay does not help — it is a sibling, not a descendant. It is a real header control now.

Research document header collapsed to one word per line: flex-1 measures as zero when deciding whether a row fits, so the actions never wrapped and the title just shrank.

Verification

bun fmt, bun lint (exit 0, 261 warnings — one below the 262 baseline), bun typecheck (8/8) all pass locally. Test suites left to CI.

Not verified

None of this has been watched end to end in the running app. Drag hit-testing across nested flex containers, localStorage rehydration timing versus first paint, and the peek's pointer edge cases are all things only real use surfaces.
