* fix(workspaces): observe setup output only in the visible setup panel
Setup logs were requested for the whole session, including unrelated workspaces. Use directory status for discovery and source-owned workspace observations for details, preserving legacy delivery only for clients without the negotiated capability.
* fix(workspaces): publish external setup progress once per daemon
MCP and scheduled setup enter through the broadcast API. Publish them to the shared setup owner before session fanout so each observation gets one update and snapshots survive periods without connected clients. Keep the setup action available on older hosts to explain the required host update.
* fix(app): replace setup details with each observation snapshot
A host restart can return an empty setup snapshot. Apply that authoritative snapshot so an open panel does not retain output from the previous daemon. Assert setup membership requests as well as delivery in the browser lifecycle regression.
* test(workspaces): cover setup status catch-up after directory release
* test(workspaces): synchronize setup output and release fixture resources
Paseo subagent rows in the subagents list had an empty info strip: the row
only rendered the daemon-provided subtitle, which only provider subagents
carry. The row now uses the same facts line an agent's sheet shows when it
opens without its composer, so both surfaces resolve model, thinking, mode,
and context the way the composer's controls do.
The facts sit under the title instead of beside it, so a long task name
keeps the row's width instead of fighting the strip for it.
* Put sheet tabs on the one sheet stack
Sheets are one primitive with one stack. A sheet opened from any sheet
stacks on top of it, and closing it uncovers the sheet underneath. The
compact workspace's file and subagent sheets were an in-tree Gorhom
BottomSheet with their own stacking, so a subagent chosen from the
subagents list sheet replaced the list instead of covering it.
- SheetHostScope: a subtree hosts the sheets presented inside it, so the
sheet tabs draw inside the compact column and read the workspace
providers while still joining the app-wide stack. Needs Gorhom's
BottomSheetModalInternalProvider, which the patch exports.
- IsolatedBottomSheetModal takes enableDismissOnClose; false keeps the
content mounted through a close so the unsaved-changes guard can veto
it. Its backdrop then closes the sheet rather than dismissing the top
modal. The Gorhom patch also keeps a dismissing modal's status through
its final onChange(-1), without which such a modal unmounting while
presented never left the portal.
- SheetTabs (was WorkspaceSheetHost) renders one IsolatedBottomSheetModal
per store entry. The store never reorders sheets; a reveal of a covered
sheet drops the unmodified sheets above it.
- Subagent rows that open a sheet keep the list open (closeOnSelect
false); rows that open a tab still close it.
- A menu closes when its retained panel goes inactive, instead of hiding
and reappearing with the panel on the next tab switch.

* Show an agent's model and thinking in its sheet, and fit Open as tab in the header rail
A Paseo agent shown in a sheet has no composer, so the facts the composer's
model and thinking controls would show now sit in one line under the sheet
header, the same row provider subagents already get from the daemon. The line
resolves exactly as the controls do (resolveAgentModelSelection), from the
session agent and the providers snapshot, and shows wherever the pane host is
a sheet.
Open as tab becomes the full-screen glyph beside Close, drawn by the shared
SheetHeaderIconButton, so the title keeps its width. The tab switcher sheet is
titled "Workspace tabs" so it reads as what it lists.

* Show mode and context usage in the sheet facts line
The line under a sheet's header now carries everything the composer's
controls and context meter show: model, thinking, mode, and used/max context
tokens with the share, each resolved as its control resolves it.

* Re-render subagent rows when the workspace's tabs change
A row decides at render time whether choosing it opens a sheet or reveals
a tab, and keeps the list open only for a sheet. The hook behind it only
subscribed to the layout mode, so a row rendered while its agent was a
full tab kept closing the list after that tab was gone: on iOS, promoting
a managed child, closing its tab, and reopening it from the list dropped
the list under the sheet. Subscribe to the workspace's layout too.

* feat(app): open files and subagents in a closable sheet on compact
On phones, opening a file, a provider subagent, or a Paseo subagent now shows it
in a bottom sheet over the current tab instead of adding a tab, so the tab strip
stays for terminals and root agents. Paseo subagents get "Open as tab" to move
the same tab (same tabId and state) into a full tab with a composer; agents in a
sheet hide the composer.
The decision lives in the workspace layout store's openTab, driven by a
per-kind `compactSheet` rule in the panel manifest, so every open path (chat
links, Explorer, subagents track, notifications, plugins) follows it without
call-site branching, and a new kind opts in with one manifest entry. The app
shell publishes the layout mode (compact / single-pane / split-panes) once, so
callers stop passing isCompact for placement.
A sheet holding unsaved edits is never implicitly displaced; later opens go to
tabs underneath, and closing it goes through the existing discard guard. The
editor host is position: sticky because CodeMirror's scrollIntoView otherwise
scrolls the bottom sheet's container and drags the sheet to full height.

* feat(app): unify Explorer tabs and refine interface styling
Give Explorer the workspace tab controls while keeping launcher choices separate from drag-and-drop support.
Upgrade Lucide and set a shared icon stroke width for consistent styling. Reduce the desktop composer bottom inset to align the action row with its corners.
* fix(app): show active Explorer tabs in foreground
The shared row coupled foreground styling to keyboard shortcut ownership. Separate those concerns so Explorer can highlight its active tab while Cmd+T remains with the workspace pane.
* fix(app): refine Explorer close controls and launch options
* test(app): respect singleton Files in Explorer plugin workflow
* test(server): trim unused setup from no-track checkout regression
* test(app): count visible main tab rows after pane moves
* feat(app): let users set the chat and Markdown content width
Wide and ultrawide screens were stuck with an 820px reading column. The
width is now an Appearance setting that flows through the Unistyles theme,
like the font sizes, so every content surface picks it up.
The stored value stays null until the user picks a width, so a future
change to the default reaches everyone who never customized it. Reset
writes null back.
The native composer dock keeps plain React Native styles and takes the width
inline because those styles land on Reanimated views, where theme-driven
Unistyles crash on theme changes.
* fix(app): pass the content width into the web stream viewport
The viewport read app settings itself, which required a QueryClient in every
render of the stream strategy. The agent stream view already reads settings,
so it hands the width over with the rest of the render input.
* feat(auth): authenticate daemon clients through hello
Give local CLI and desktop clients a per-run credential while remote clients send the host password inside the protocol. Keep relay passwordless admission for this mobile release so existing saved hosts keep working until the follow-up enforcement release.
Move password recovery for saved hosts into host settings and keep pairing credentials in the add flow. Include isolated web QA evidence for both flows.
* fix(auth): preserve Hub bootstrap and local credential expectations
Hub-owned sockets already carry admission; keep their hello handling synchronous through session bootstrap while resolving credentials asynchronously for ordinary sockets. Keep the resolver out of lightweight configuration imports.
Update CLI expectations for same-home credentials, let a rejected connection yield to another usable connection, and clear pairing secrets when add-flow targets change.
* fix(pairing): retain passwords across edits to the same target
Track the last valid pairing host while a URI is edited. This preserves an entered password for whitespace and partial edits but clears it when a different host becomes the target.
* test(auth): align local credential checks across platforms
Expect the CLI to authenticate through the credential in its selected home, and verify POSIX file modes only where Node exposes them.
* feat(app): move host password into a settings row with a modal
The host page rendered an always-visible password form above Name on every
host. Replace it with a Password row under a Security section below
Appearance; tapping it opens a modal with Save and, when a password is saved,
Clear. The connection-error callout keeps its guidance and gains a Set
password button that opens the same modal. Drop the unused
pairing.hostPassword body/reopen/saveError strings.
* chore: remove committed QA screenshots
QA evidence stays out of the repository; the PR body describes it in words.
* feat(app): keep the host password out of the host page
The saved password is connection data, entered only when a host is added. A
Password setting on the host page reads as the daemon's own password, so the
row, modal, and callout button are gone. A rejected host shows the daemon's
reason with guidance to remove the host and add it again with the password.
useHostMutations no longer exposes setHostPassword; relay imports still set it
inside the runtime.
* feat(app): show host connection errors in an error alert
HostConnectionError renders the existing Alert with the connection error as
its title. Auth rejections add the re-add guidance as the description; other
errors show the title only. The Overview and Connections pages share it.
* style(app): soften alert borders to half-opacity accent
* feat(app): size alerts on the button scale
Alert takes a size prop (xs/sm/md/lg, default md) whose geometry lives next to
the button's in control-geometry: one font size for title and description, the
button icon size centered on the first text line, button padding and radius,
and a one-line alert as tall as the button of the same size. Consumers pick
sm among settings rows, cards, panels, and modals, and md when the alert is
the whole page or sheet state.
* style(app): roomier, rounder alerts with a tight title block
Alert sm padding returns to the original 12/16 and every size is at least
borderRadius.xl. Title and description sit a small gap apart with no line
height override. The icon slot carries a zero-width text strut in the alert's
font so the icon centers on the first line for titled, title-only, and
description-only alerts.
* refactor(app): align the alert icon with a centered lead row
Drop the zero-width strut. The icon and the alert's first text (title, else
description) share one row centered on each other; the description and actions
sit below, indented by the icon slot width plus gap so they start at the lead
text's left edge.
* refactor(app): drop the unused Alert icon override
* fix(app): dock the New workspace composer like a chat on phones
Only the composer is bounded by the viewport; the setup fields sit above it in a
bottom-anchored stack that moves up as the draft grows. The keyboard reservation
is retained on every screen, so the composer keeps one height across keyboard
transitions. Removes the per-screen reserve policy.
* fix(app): share composer docking across mobile hosts
Extract chat's retained capacity and platform keyboard motion so chat,
workspace drafts, and New workspace share one sizing and dismissal boundary.
Keep the native drivers and settled portal reconciliation unchanged.
* fix(app): preserve overlays in centered composer docks
Honor the optional overlay child in both layouts so changing dock placement does not silently discard part of its content.
* test(app): resolve keyboard controller through its web entry
The shared keyboard entry point makes stream tests load the provider. Keep its real ESM dependencies inside the Vitest resolver so CommonJS does not bypass the React Native web alias and parse native Flow sources.
* fix(app): keep native chat scrolling responsive
Place keyboard dismissal behind scrollable content so an idle Android Fabric JS responder cannot intercept native drags. Keep decorative form padding transparent to iOS hit testing and exercise idle native scrolling after submission from every composer host.
* fix(app): stabilize native composer sizing after edits
* test(app): verify workspace composer space after keyboard dismissal
* test(app): start the hold-to-delete regression mid-draft
From the end of the draft the pre-fix input also returns to baseline. Placing the cursor
eight lines into the draft before the first hold-delete leaves the old build at the
capped height with the placeholder visible, and the fixed build at one line.
* fix(app): preserve composer capacity when the keyboard closes
Releasing the keyboard reservation enlarged an unchanged capped draft. Retain the last editing reservation while still recalculating capacity for viewport changes and subsequent keyboard openings.
* perf(app): isolate composer editing and resize updates
Draft and cursor subscriptions rerendered the chat and full composer on every native edit. Give editing consumers a live text source, preserve attachment identity on text updates, and read viewport settling state without a render.
Read live input text for web resize measurement so removing per-keystroke props does not collapse a draft when its width changes.
* fix(app): restore current draft when the composer remounts
The last replacement command does not include subsequent edits. Seed remounted editors from the live draft snapshot so switching launch modes restores the saved text without subscribing the composer to every edit.
* fix(app): synchronize composer resolution state before paint
Avoid an extra passive-effect delay when forwarding forge resolution state from the isolated binding. Exercise live-text width measurement through the actual composer E2E journey instead of a hook-only test component.
* fix(app): keep open chats current and show resume progress
Keep open-chat delivery independent of mounted views, freeze hidden chat rendering, and catch up visible chats before hidden ones. Distinguish host reconnection from timeline freshness so cached messages do not silently appear current after resume.
* fix(app): prevent sync status from overlapping action errors
Share the existing panel toast slot so action errors remain readable during reconnect and catch-up. Verify the interaction and draft retention in the real browser, preserve the tested freeze transition, and refresh the Nix dependency hash for react-freeze.
* test(hub): expose complete creation and message retry failures
Partial response assertions hid the creation error and allowed duplicate responses with incomplete agent data. Check complete success envelopes, the shared agent snapshot, and null message errors so future failures print the actual error payload.
* fix(app): dismiss retained chat menus before freezing
An async fork navigates before its closing state commits, so freezing the source chat could leave its portal backdrop blocking the destination. Remove the shared menu surface in the inactive commit before suspension.
Keep regression assertions aligned with open-chat subscriptions, per-agent incremental recovery, plugin contribution lifetimes, and rendered image completion.
* test(app): expect the reloaded plugin to contribute its pill again
A full reload discards the pressed pill with the page, then evaluates the plugin again and its agents snapshot re-adds the pill. The old count-zero assertion only passed on main because the chat was not ready yet when the URL settled; open chats now subscribe from session start, so the pill is rendered by then.
* fix(app): suspend hidden chats on web only
react-freeze is Suspense with a never-resolving thenable. Suspending a committed subtree hides its host nodes, tears down layout effects, and detaches refs, which changes Fabric ownership of the retained chat. Split the boundary by platform: the web file keeps the two-commit freeze, the native file keeps the chat mounted and live, and the retained-panel signal remains the only thing that stops background work. Restore the mobile-panels rule the branch had rewritten.
* fix(creation): never read a receipt while replacing it
Admission reads the creation receipt while the runner replaces it atomically. On Windows a rename over a file this process still has open for reading fails with EPERM, and that error marked an otherwise completed creation as failed (#4865). Queue reads and writes per receipt so one owner never overlaps them, and serialize the record when the write is queued because the runner mutates it afterwards. No retry on EPERM: the conflict is removed rather than tolerated.
Linux cannot reproduce the rename failure, so the Windows server-tests job (creation/index.test.ts and hub/execution-session.websocket.test.ts) is the verification for this change.
* fix(agents): prevent OOM from cumulative tool history
Repeated progress updates retained complete historical copies of growing tool output. Retain projected items on ingestion and serve them for every history fetch, preserving source sequence coverage for catch-up. Keep intermediate payloads only in streaming; confine compatibility degradation to child transcripts and overwritten fork checkpoints.
* test(client): expect projected subagent capability in hello
* fix(app): report unexpected child history failures
Keep connection failures recoverable while forwarding unexpected fetch and reconciliation errors to diagnostics. Name observer arguments to keep server and agent identities explicit.
* test(agents): assert projected history after rewind
* docs(protocol): tag projected child compatibility gates
* fix(app): keep growing composers below the header
Native keyboard translation left the dock at full height, so intrinsic composer growth could extend behind the header. Reserve the keyboard destination at motion boundaries and bound the composer to its stationary viewport while preserving native input scrolling and animation.
* docs: reuse existing test suites and automation
* fix(agents): restore archived Codex workspaces without losing focus
History selection must survive without cached agent records, and reading an archived Codex thread must not acquire an interactive writer. Keep workspace restore explicit, serialize native lifecycle transitions, and leave transcript lifetime with its owner.
* test(app): express Codex restore specs as user journeys
* test(app): finish restore fixture cleanup after teardown errors
* test(app): align restore coverage and await fixture readiness
Workspace restore leaves agents archived until explicit Unarchive. Keep that distinction covered for multiple agents. Compile the recovery fixture before its interaction test starts, and wait for sidebar agent hydration before asserting tab presence.
Restored tabs render before the terminal list arrives. Mark their titles as loading until metadata is available so they do not briefly display the generic terminal name.
* perf(app): restore live sessions immediately after resume
Foregrounding now reconnects every host without waiting for scheduled backoff, while cached turns, timelines, agents, and workspaces remain internally consistent until authoritative catch-up arrives. Replica persistence is keyed and incremental so ordinary updates avoid whole-directory serialization.
* fix(app): preserve turn ownership through session updates
Stream turn closure now wakes queued-message delivery, while same-turn snapshots retain local cancellation state. Offline liveness remains visible until an authoritative close arrives.
* fix(app): preserve pending chat cache writes and trim resume refactor
Directory baseline replacement must preserve independently accepted timeline changes until the deferred flush. Keep the reconnect and persistence fixes while removing the session-data facade and broad read-hook migration.
* fix(app): initialize reconnect policy from current app state
Initialize visibility before host bootstrap so a background mount cannot leave reconnect enabled. Seed sidebar fixtures through the workspace owner so cache hydration preserves their rows.
* test(app): verify submission settlement across reconnect
Keep submission acknowledgement separate from turn liveness: disconnect preserves the running turn until authoritative catch-up. Wait for confirmed running chrome before exercising queued cancellation so the alternate-send shortcut cannot race turn startup.
* docs: remove cache implementation recap
* fix(subagents): preserve recursive provider ownership
Provider events retained enough lineage to identify nested work, but the canonical descriptor discarded the direct owner. Preserve that relationship at ingestion so child timelines and hierarchy remain attached to the process that emitted them, including after history replay.
* test(e2e): clarify nested ownership journey
* test(e2e): separate nested ownership actions
* fix(subagents): retain nested ownership across replay
Wait and interaction events can reference descendants without spawning them. Preserve the original spawning owner and route persisted background notifications through that same relationship after history reload.
* test(subagents): hide provider turn plumbing
* fix(subagents): scope nested tracks to their host
Plugin-provided icons are host-specific. Carry the panel host through nested child tracks so the rebased ownership UI resolves the same provider presentation as its parent.
* fix(workspaces): preserve launched terminal focus
Allow trusted local plugins to register complete coding-agent providers through the existing agent lifecycle. Includes direct and ACP implementations, SVG provider icons, custom timeline items, runnable examples, and public authoring documentation.
Closes#3547Closes#3556
* perf(app): smooth mobile keyboard transitions
Animating dock padding forced Fabric and Yoga to relayout the chat tree on every keyboard frame, producing visible stepping and React list churn. Keep the surface full-height and move it as one translated unit, with scroll range and portal measurements updated only after keyboard motion settles.\n\niOS keeps its native keyboard animation driver behind the same component boundary because its Reanimated signal reports the endpoint at animation start.
* fix(app): isolate native keyboard implementation
* feat(workspaces): gate fork repository automation
Cross-repository change requests can execute contributor-controlled package hooks even when the setup command comes from the base repository. Persist the checkout provenance and require one explicit workspace-level setup action before repository automation runs.
* fix(workspaces): clarify blocked script errors
* fix(app): keep long toasts readable
* test(server): expect fork repository provenance
* test(server): make setup marker portable
* test(app): retry transient sidebar layout
* fix(app): keep Changes comparison and diff in sync
Own the working comparison at the workspace checkout so the Changes tree and adjacent working diff share it. Immutable commit diffs remain scoped to their commit SHA.
* docs(app): align working diff ownership notes
Allow the composer constraint chain to shrink inside KeyboardDock so overlong drafts scroll internally without hiding controls behind the IME. Extend the Android keyboard invariant to cover the maximum-height case.
The keyboard-sync change needed submission blur to dismiss the native keyboard, but applying it to every platform interrupted consecutive keyboard-driven messages on web and desktop. Keep submission blur native-only.
* fix(app): keep chat synchronized with keyboard
Dock the complete chat surface with worklet-driven layout padding so visual and native touch geometry move together. Reset cleared multiline native inputs and keep autocomplete portals anchored to the docked composer.
* fix(android): tolerate detached composer inputs
Return the nullable base input connection during IME restart instead of force-unwrapping it after the composer has blurred or unmounted.
* fix(app): restore rewound text atomically
The native composer could consume a replacement revision before the matching draft-store value arrived, leaving the mounted input blank until remount. Carry the replacement text with its revision so scheduling order cannot split the command from its payload.
* fix(app): isolate launch composer drafts
Give chat and terminal launch composers separate React identities so each uncontrolled editor lifetime remains owned by its draft mode.
* fix(app): paint cached conversations before reconnect
Cold startup restored every saved host before publishing any session, so a valid cached chat was blocked behind unrelated directory validation and network-only readiness. Directory and timeline owners now resolve demand through typed storage and authoritative reconciliation while consumers remain source-agnostic.
* fix(app): stabilize demand-driven cache restore
Create host projections before network availability, route cached workspace and timeline preparation through their owners, and coalesce directory reconciliation per online connection. Update browser cache fixtures for per-agent timeline rows.
* fix(app): resume cached timeline through owner
* fix(app): surface timeline owner load errors
* fix(app): route workspace actions semantically
Separate Explorer visibility from view navigation, and give composer changes and pull request opens semantic routing owners. Unify diff destinations, keep compact PR navigation in Explorer, and derive maximize availability from visible workspace panes.
* test(app): cover composer changes routing
Update the browser journey for the Explorer-first composer action, then assert the second press follows the shared diff destination.
The Explorer pane rewrite routed semantic Changes and pull-request actions through ordinary workspace tabs on compact layouts. Centralize those actions so mobile and native dock layouts select the Explorer surface while desktop keeps its placement preferences.
* fix(rewind): refresh canonical timeline after rewind
A rewind replaces the daemon timeline and epoch, but replaying the rebuilt history made long conversations visibly reload from the beginning. Capable clients now refresh the existing bounded tail path after a replacement signal while legacy clients retain replay compatibility.
* test(rewind): cover coherent timeline replacement
Hold rewind completion in the browser regression so it can verify the existing pending state and detect any reconstructed timeline rows before the normal tail refresh is allowed to finish.
* feat(app): open the tab chooser beside the pointer
Keep keyboard-created and empty-pane New tabs as persistent launcher surfaces, while giving pointer users an anchored chooser at the pane-local plus button. Both presentations resolve the same launch catalogue so future ordering and customization cannot drift.
* test(app): follow the anchored tab chooser
The browser helpers still searched inside the pane for persistent-launcher controls after clicking the portalled menu trigger. Exercise the menu through its own roles and stable catalogue IDs.
* feat(app): replace empty panes with New tabs
Give every retained pane an independently identified New tab, replace it in place when a destination is chosen, and preserve split close and move invariants. Keep existing workspace startup and compact explorer routing explicit, with focused unit and browser regression coverage.
* test(app): count content tabs in subagent integration
* fix(app): preserve workspace shortcut ownership
Restore compact message and footer spacing, reserve independent composer-pill clearance for transcript content and floating controls, and keep visible web tool-call expansion from shifting the reading position.
* fix(app): keep file navigation in place
Retargeting a File tab allocated a new tab identity, causing the tab track to unmount and remount during navigation. Preserve the identity for File-to-File changes while retaining new instances for cross-kind replacements.
* feat(app): expand workspace panel actions
Keep the Command Center aligned with workspace tab and pane primitives. Add explicit panel placement, focused open behavior, keyboard navigation for empty panes, and a Changes pill that toggles the visible Side panel without closing its tab.
* feat(app): refine workspace pane actions
Prioritize Changes when available, keep Files useful before a selection, and reserve desktop diff clicks for selection so comments require the explicit affordance. Move the Changes shortcut to Shift+G to avoid consuming a likely copy variant.
* feat(app): improve access to workspace changes
* fix(app): restore smart Changes comparison selection
The tab migration persisted the selected comparison, pinning Changes to an empty view after checkout state changed. Keep comparison overrides ephemeral per surface and expire them when dirtiness changes, while preserving only presentation state in tabs.
* chore(app): date Changes compatibility cleanup
* feat(app): let the file panel close its tree rail
The file panel's tree rail was permanent on desktop — the changes panel
had a folder-tree toggle in its toolbar, the file toolbar had nothing, so
the rail was there whether you wanted it or not.
The changes panel's private DesktopTreeToggle becomes a shared
TreeRailToggle so both toolbars render the same affordance; that also
drops the treeToggleStyle prop threaded through ChangesToolbarProps,
which recomputed exactly what the component already built internally.
The i18n keys move out of workspace.git.diff into workspace.tree, since a
shared component reaching into the git namespace would rot.
The two rails keep independent flags — the file rail in panel-store, the
changes rail in useChangesPreferences — so closing one leaves the other
alone. FileTreeToggle wires itself to the store rather than taking a
callback: the bar renders several components below FilePanel, where the
rail actually lives.
Both rails also get narrower (320 -> 260 default, 200 -> 180 minimum).
The persist version bump resets treeRailWidth on purpose: nearly every
existing install carries the old 320 default, so without the reset the
narrower rail would only ever reach new users. Anyone who dragged their
rail to a deliberate custom width loses it once.
Note that MIN_CONTENT_WIDTH still clamps the rail to
`containerWidth - 240`, so in a narrow pane the new default never
applies — that floor, not the default, is what sets the width there.
* feat(app): make the side panel an empty workspace surface
The fixed, hideable side panel keeps supporting context beside an agent without seeding content. Pane-local choices stay local, while implicit supporting opens follow a persisted routing preference.
* test(app): exercise side panel policy through its capability boundary
The browser rail journey already covers the real tree-toggle behavior. Side-panel policy tests now pass their platform capability through the public boundary instead of replacing a production module.
* test(app): expect an empty side panel after upgrade
* test(app): expect an empty first split pane
* test(app): account for the empty side panel in split retention
* feat(app): make workspace panel tabs independent
Give explicit New actions fresh tab instances, keep panel state opaque to tab management, preserve File navigation context, and stabilize uncached File transitions.
* fix(app): preserve file conflicts during preview refresh
Keep the current preview mounted for same-target reads and conversions so the editor retains its conflict observation state. Clear retained previews only when the file target changes.
Upgrading to 0.5.0-beta.1 left the old docked explorer sidebar showing
next to the new explorer pane, with no way to dismiss it.
The sidebar rendered off the persisted `desktop.fileExplorerOpen` flag.
#3287 rerouted the explorer toggle to the workspace-layout explorer pane,
so nothing on a wide layout ever wrote that flag false again, and no
migration cleared it. Assistant directory links and review attachments
could still set it. On Windows and Linux the sidebar's close button was
suppressed because the OS window controls own the top-right corner, so
there was no affordance at all.
The explorer is now one surface picked from two facts — is the layout
compact, and can the platform render split panes:
compact -> slide-over overlay (panel store)
non-compact + splits -> dedicated right pane (layout store)
non-compact, no splits -> ordinary tabs in the focused pane
`workspace-tabs/explorer-surface.ts` owns that choice and every entry
point routes through it, so the toggle, Ctrl+E, Ctrl+., directory links,
review attachments and side file opens can no longer disagree about where
the explorer lives.
Pane splits stay gated on `isWeb`: they depend on dnd-kit and DOM-backed
accessibility helpers. Native tablets are non-compact without splits, so
they get explorer tabs rather than a second pane — deliberately trading
side-by-side agent and Changes for a surface that only renders what the
single-column tab row can actually reach.
Ctrl+. is handled by the workspace screen rather than the app shell. The
pathname alone cannot identify the active workspace: desktop cold-starts
at "/" and restores the remembered workspace from route params, so a key
derived from the pathname is null exactly when a workspace is mounted,
and the explorer reads as permanently closed.
`desktop.fileExplorerOpen` and `explorerWidth` are dropped by a migration
to panel-state v15 but stay declared in the persisted schema. That schema
is a strict object and the validated storage deletes the whole entry when
parsing fails, so removing the keys outright would wipe every upgrading
user's sidebar width, expanded paths and diff-collapse state.
Tapping a subagent or provider subagent from the composer track now opens its tab in the explorer companion pane when desktop split panes are active, keeping the parent agent visible in the primary pane.
Mobile and compact layouts continue using single-pane tab navigation, and cross-workspace subagents continue routing to their own workspace.
A host can refuse a timeline read for as long as it likes. Codex does
this whenever another writer holds the thread: every catch-up fails with
"already has an active writer" until the other session lets go. The app
retried that on a fixed 1s timer with no ceiling, so an idle window sat
there issuing a request and logging a warning every second, indefinitely.
The refusal is normal lifecycle; the traffic was the bug.
Catch-up and subscription retries now double from 1s to a 30s ceiling,
resetting on success, reconnect, delivery-mode change, and visibility
change so recovery stays immediate once the condition clears.
Backing off alone would leave the user waiting up to 30s with no way in,
so both failure surfaces get a retry they can press. Background retries
stay silent; a retry the user asked for is a fallible user action and
owns its pending state, so "retrying" is a status the sync model
publishes rather than a React boolean.
The blocking "Failed to load agent" screen was the worse half: its load
effect self-gates on the error state, so a refused first resume was
terminal until the user navigated away. Its retry resets the state to
idle, which re-arms the effect.
Layout measurement excluded pill margin on some renderers, collapsing the intended gap above visible tracks. Keep the two-pill rail on one line and derive its complete tail clearance from shared geometry so chat switching and layout callbacks cannot change the result.
Keep the roomier 16px separation on compact layouts while using 10px on wide layouts. Apply the same breakpoint contract to track and import-session pills so their spacing stays consistent.
The empty-state text inherited the platform default color, making it unreadable on dark surfaces. Use the app foreground tokens so it follows the active theme.
