José Almeida 3bc092bf20 feat(terminal): first-class user terminals — stable seq, rename, park/resume (#1009)
* feat(terminal): persist user terminals with stable seq + park state

Ordinary user shells now have a DB-backed `user_terminals` row keyed by
the agentctl PTY id, carrying a per-task monotonic seq (gaps preserved on
delete), custom_name override, and open/parked state. The terminal
service owns the create/list/rename/park/resume/destroy surface and
guards reject `bottom-panel` (cmd+J) + `script-*` ids so passthrough
flows are untouched. Closing a tab now parks (PTY keeps running);
destroy kills the PTY and removes the row.

* feat(web): expose terminal seq badge, rename, and parked-terminals menu

Wires the right-panel strip and SSR page state to the new task-keyed
terminals endpoint and discriminated UserShell union, adds the `#N`
badge for ordinary terminals, plumbs context-menu / double-click rename,
and renders a "Parked" submenu so closed-but-running terminals can be
resumed. Closing a managed tab now parks instead of destroying so the
PTY (and its buffer) survives accidental closes.

* test(terminal): e2e coverage for first-class persistent entities

Covers the persistence guarantees the user explicitly called out:
monotonic seqs, refresh-survives-rename-and-park, gap-preserving destroy,
park+resume cycle, and bottom-panel/script guards. Exercises the new
user_shell.{create,list,rename,park,resume,destroy} WS actions through
the shared ApiClient.wsRequest helper.

* fix(terminal): atomic seq allocation + propagate destroy errors

- Repository.Create folds MAX(seq) read + INSERT into a single
  `INSERT … SELECT` statement so concurrent creates can no longer pick
  the same seq. Locked in with TestCreate_ConcurrentSeqAllocation (25
  parallel creates, all unique).
- wsUserShellStop now propagates the service-Destroy error so the
  frontend stops optimistically removing a row the backend failed to
  delete.
- Service.Destroy / CleanupTask log PTY-stop failures at Warn (instead
  of silently swallowing) while keeping the proceed-on-failure semantics
  intentional — the DB row is the source of truth for "user expects
  this terminal gone".
- IsUserShellAlive copies ProcessID under the read lock before calling
  r.Get(), removing the post-unlock pointer-deref race.
- Get-not-found test asserts errors.Is(err, ErrNotFound) so it locks to
  the repository contract.

* fix(web): close-tab waits for backend ack + className undefined guard

- handleCloseTab defers `removeTerminal` into the `.then()` of the
  park/destroy promise. A failed backend call leaves the tab visible
  rather than vanishing it optimistically; the next `user_shell.list`
  poll reconciles state.
- session-tabs guards `tab.className` with `?? ""` so an undefined value
  no longer produces "undefined group relative..." in the rendered
  class string.
- user-shells.test simplification: `createSessionRuntimeSlice` only
  consumes `set`, so the test passes the slice creator straight to
  `immer()` instead of wrapping it in an adapter with unused args.

* fix(terminal): task-scoped mutations + legacy-shell list + UI hardening

Round-2 review feedback (cubic P1/P2, claude, coderabbit):

Backend:
- Rename/Park/Resume/Destroy now require a task_id and verify the
  terminal belongs to that task via a shared requireOwnership helper.
  Cross-task mutations return ErrTaskMismatch instead of silently
  succeeding by raw terminal id.
- wsUserShellList no longer drops managed-shaped agentctl shells when
  the terminal service is disabled or task_id is missing — legacy
  passthrough callers see their existing shells again. `managedCovered`
  flag scopes the orphan filter to the DB-backed path.
- service_test.go uses the shared-cache in-memory SQLite + MaxOpenConns(1)
  setup, matching repository_test.go and removing the flake-one-race-away
  warning.
- New cross-task guard tests: TestRename_RejectsCrossTask,
  TestPark_RejectsCrossTask, TestDestroy_RejectsCrossTask, plus a
  TestRename_EmptyTaskIDSkipsOwnership for internal callers.

Frontend:
- updateUserShell patch type narrowed to Partial<Omit<UserShellInfo,
  "terminalId">> so the row key can't be silently mutated.
- destroyUserShell now throws on a missing WS client instead of silently
  resolving — handleCloseTab's .then() no longer fires prematurely.
- rename/park/resume/destroy API client + useTerminals hook plumb the
  active task id through every mutating call.

E2E:
- New "cross-task mutating ops are rejected" spec creates a terminal
  under task A and verifies task B can't rename/park/destroy it by raw
  id.
- Existing specs updated to send task_id with their mutating calls.

* fix(terminal): require task_id on all mutators + wire taskID into hooks

Round-3 review feedback (cubic P1, claude blocker, coderabbit):

Backend:
- requireOwnership no longer skips the ownership check when taskID is
  empty. The previous carve-out was reachable from the WS layer (where
  task_id is user-controlled), so an attacker who guessed a terminal id
  could omit task_id and mutate any row. CleanupTask walks the repo
  directly and never touched the bypass.
- TestRename_EmptyTaskIDRejected pins the new contract.

Frontend (the real bug claude caught):
- useUserShells now accepts a taskId parameter and forwards it on the
  user_shell.list WS call. Without it the backend's DB-backed ordinary-
  shell path was skipped and the Zustand store wiped the SSR-hydrated
  panel strip on the first WS fetch.
- Response mapping switched to a discriminated union: id (new field)
  falls back to terminal_id (legacy), and kind/seq/state/pty_status/
  display_name/custom_name flow into the store so the parked-terminals
  submenu actually populates.
- useTerminals + useMobileTerminals read the active task id from the
  store and pass it through to useUserShells.
- destroyUserShell now retries with user_shell.stop when the server
  returns an unknown-action error — keeps the rollout-window
  compatibility intact for older backends that only know the legacy
  action name.

* fix(terminal): list parked, rollout-safe kind default, helper extraction

Round-4 review feedback (claude + greptile P1):

- useUserShells now sends include_parked: true so the "Parked terminals"
  submenu populates after a page reload. Previously the WS list returned
  only state=open rows; parked terminals were invisible until the user
  parked something in the same session. The main strip still hides
  parked entries via buildTerminalsFromShells.
- useAddTerminal stops blindly defaulting kind to "ordinary" — that
  misclassified legacy passthrough payloads (terminal_id without seq)
  during a rollout where the frontend is newer than the backend. The
  managed-tab path then called parkUserShell on a server that didn't
  know the action. Now only tags as ordinary when kind is explicit or
  the row carries a seq.
- handleCloseTab extracted into a standalone useCloseTab + helpers
  hoisted into use-terminals-build.ts / use-terminals-types.ts. Brings
  use-terminals.ts back under the 600-line file limit and the
  useTerminalActions wrapper inside the 100-line function limit.

* fix(terminal): scope-keyed shell cache + null-task guard + tighter rollout default

Round-5 review feedback (cubic P1, coderabbit x4):

- useUserShells now keys its fetch cache on env+task (`${env}:${task}`),
  not just env. An earlier load without a task id (e.g. before the
  active task hydrated) no longer pins the store on a legacy-only shell
  list and blocks the task-scoped refetch.
- useMobileTerminals delays auto-create until a real taskID is
  available. Previously a null taskID could bootstrap a legacy
  non-persistent shell, mark the env as auto-created, and starve the
  real task of its first-class terminal. Guard key is now env:task, and
  releaseAutoCreatedEnvironment clears every scope on that env.
- useAddTerminal tightens the rollout check: a row is "ordinary" only
  when `seq !== undefined`. A bare `kind: "ordinary"` without seq from
  an older backend stays legacy so close → destroy on the first click.
- useRemoveTerminal reads the current activeTab from a ref instead of
  closing over the value captured when handleCloseTab first ran. Async
  park/destroy resolves after a user tab-switch no longer clobber the
  newer selection with the stale fallback shift.

Tests:
- New "waits for taskID before auto-creating — null taskID is a no-op"
  case in use-mobile-terminals.test.ts confirms the null-task guard.
- All existing mobile-terminal + slice + E2E tests pass.

* fix(terminal): live activeTab lookup + selectable-tab guard

Round-6 review feedback (cubic P2 x2):

- getActiveTab now reads the active tab from the Zustand store via
  storeApi.getState() instead of a useRef/useEffect pair. Closes the
  post-render race where an async close handler could resolve between
  the new render's commit and the effect-driven ref sync.
- computeTerminalTabValue requires activeTab to be selectable
  (present in `terminals` or === "commands") before honoring it. A
  stale id left over from a parked/destroyed terminal no longer pins
  the panel on a nonexistent tab and blocks the fallback shift to a
  real shell.

* chore(terminal): inline savedTabFromStorage to drop file under line cap

Round-7 review feedback (claude suggestion): the useMemo around the
synchronous getSessionStorage call was zero-value memoisation that
pushed use-terminals.ts three lines over the 600-line max-lines limit.
Inlined; file now at 600 lines.

* chore(terminal): drop savedTabExists local + comment to land under 600 lines

Round-8 follow-up (claude): the previous commit's two-line comment block
held the file at 603 lines (still over the 600-line cap). Inline
savedTabExists at the only call site and remove the redundant comment —
the round-7 PR thread already explains why the useMemo was removed. File
now at 599 lines.

* fix(terminal): plumb task_id through dockview + tolerate legacy destroys

Manual-test feedback: clicking X on a dockview terminal panel surfaced
"destroy terminal: terminal does not belong to the supplied task" because
the dockview path was creating + destroying terminals without sending
task_id at all. The new requireOwnership guard then correctly rejected
the empty task_id against a non-empty term.TaskID.

Frontend:
- addTerminalPanel grows task_id + title parameters; stamps both into
  panel params at creation time so the destroy cleanup can pass them
  back to user_shell.destroy / .stop.
- Every dockview-side createUserShell call site now passes the active
  task_id, so the backend creates a DB-backed ordinary terminal (with
  seq + displayName) instead of a legacy passthrough shell.
- destroyUserShell + stopUserShell already accepted an optional task_id;
  dockview-layout-setup.onDidRemovePanel now reads the stamped task id
  from panel params and forwards it.

Backend:
- wsUserShellStop now requires both terminalSvc and a non-empty
  req.TaskID before routing through the managed service. An empty
  task_id falls through to the legacy passthrough StopUserShell so older
  clients (and dockview panels persisted before task_id was stamped)
  keep working.

Known follow-ups (separate task): the #N badge, rename context menu,
and parked-terminals dropdown still only show on the mobile/tablet
right-panel strip. Desktop dockview shows the seq inside the panel
title text but doesn't expose the badge/rename/parked-list UI yet.

* feat(terminal): dockview tab badges + rename context menu + existing-terminals list

Manual-test feedback round 2:

- Custom dockview tab component (TerminalTab) renders the #N pill
  only when the active env has more than one ordinary terminal —
  mirrors the session-tab badge semantics. Right-click on any ordinary
  terminal tab now exposes Rename / Park / Destroy.
- Dockview + menu picks up a new "Terminals" section listing every
  ordinary terminal for the active task (open and parked). Clicking a
  row focuses the existing dockview panel if one is mounted, otherwise
  re-opens it; parked rows are auto-resumed via user_shell.resume
  before the panel is added. The base "Terminal" action was renamed
  to "New Terminal" so the existing-terminals list is distinguishable
  in the menu.
- Reopen menu uses a stable EMPTY_SHELLS sentinel for its store
  selector to avoid Zustand infinite re-renders when the env has no
  shells.

E2E:
- terminal-new-tab.spec uses getByRole("menuitem", { name: "New
  Terminal", exact: true }) to disambiguate from the new "Terminals"
  submenu label.
- Full terminal suite still passes (26/26).

* fix(terminal): tab title shows "Terminal" with seq as badge, populate store on session page

Re-reading the user feedback: the title text was rendering as
"Terminal 1" (backend's displayName), and the dockview "+" menu's
Terminals section was empty because nothing on desktop was calling
useUserShells to populate the store.

- TerminalTab.pickDisplayName now returns the literal "Terminal" for
  ordinary terminals (custom names still override). The seq lives only
  in the sibling badge — same split as session-tab where the agent
  name is the title and the seq is a pill before it. Reading "Terminal
  1" out of "[1] Terminal" instead of "[1] Terminal 1".
- LeftHeaderActions (dockview "+") now calls useUserShells on mount.
  Without this the desktop layout never triggered the WS list fetch,
  so the Terminals submenu and the badge "count > 1" check both saw
  an empty store and silently disappeared.
- TerminalReopenMenuItems also calls useUserShells defensively (cheap
  thanks to scope-keyed cache) so it works when mounted in isolation.

* feat(terminal): "New X" rows live inside their section labels

User feedback: move "New Agent" under the Agents section header and
"New Terminal" under the Terminals section header so the dockview "+"
menu reads top-to-bottom as Agents → New Agent → existing sessions →
Terminals → New Terminal → existing terminals → other panels.

- SessionReopenMenuItems accepts an optional onNewSession prop and
  renders the "New Agent" row as the first item under the "Agents"
  label. Render gate now keeps the section visible whenever the create
  handler is supplied, even with zero existing sessions.
- TerminalReopenMenuItems gets a matching onNewTerminal prop with
  the same behaviour ("New Terminal" row under the "Terminals" label).
- dockview-add-panel-items drops its standalone "New Agent" and "New
  Terminal" rows since both now live inside their sections.

* feat(terminal): auto-migrate default panel to DB-backed ordinary terminal

The legacy `terminal-default` dockview panel was hard-wired to a
non-managed `shell-default` PTY so it never picked up an ordinary
seq/customName/parked state — the new "Terminal N" badge UX could
only show a badge once the user had explicitly created a second
terminal. With useEnsureDefaultTerminalOrdinary the default panel is
upgraded into a real `shell-<uuid>` row on session-page mount, so
every visible tab is now a first-class ordinary terminal.

Plus a UI-level e2e spec asserting the multi-terminal title + badge
contract, and an expectation bump on the existing rename+park spec
since visiting the session page now mints 1 extra ordinary terminal.

* fix(terminal): park ordinary terminals on tab close so they survive refresh

Dockview's tab X close button routed straight to stopUserShell (an
alias for destroyUserShell), wiping the DB row on close — after a
refresh the user had no way to resume a still-running PTY they had
just tucked away.

The X is now a "hide for now" affordance: ordinary terminals get
parked (PTY survives, row stays in DB, reappears in the "+" →
Terminals menu with a `parked` pill), while scripts / bottom-panel /
legacy passthrough shells stay on the destroy path because they have
no resume story.

Permanent delete still lives on the right-click Destroy menu item
and (in the next commit) on each reopen-menu row.

* fix(terminal): preserve DB-backed terminal panel ids across layout restore

The serializer's normalizePanel rewrote every user-created terminal
panel id to `terminal-saved-N` and dropped environmentId/taskID from
params, so after a reload that panel couldn't be matched back to its
live PTY or its store record — the tab rendered with no badge and a
stale fallback title.

Treat `shell-<uuid>` panel ids the same way we already treat
`terminal-default`: preserve id and params on restore. Legacy
ephemeral `terminal-saved-*` ids still mint a fresh PTY on restore.
Also force tabComponent=terminalTab and title="Terminal" for any
restored terminal panel so layouts persisted before the badge UX
land on the new presentation.

* feat(terminal): destroy button on reopen-menu rows for permanent delete

Destroy used to live only on the tab's right-click menu — useless once
the tab was already closed. Each ordinary terminal row in the dockview
"+" → Terminals submenu now ends with an × button that confirms-then
calls destroyUserShell, killing the PTY and dropping the DB row so the
terminal does not reappear after reload.

Pairs with the previous close-to-park change: closing the tab parks
(soft, resumable), the × button on the menu row destroys (hard,
permanent).

* fix(terminal): reopen-menu focuses existing tab, drops parked pill, says Terminate

Three small fixes to the dockview "+" → Terminals submenu:

1. Clicking a row whose terminal is already mounted now FOCUSES the
   existing panel instead of duplicating it. The default-migrated
   panel keeps its registry id `terminal-default` even after the
   migration to a `shell-<uuid>` PTY, so a direct getPanel(uuid) miss
   would fall through to addTerminalPanel and create a second tab for
   the same PTY. Fall back to scanning `params.terminalId` so the
   lookup catches that case.

2. Drop the "parked" pill from the row — parking is now an internal
   detail (close = park) that the user doesn't need to read off the
   menu. Clicking the row brings the terminal back into view either
   way, so distinguishing it visually is noise.

3. Rename the row × tooltip + confirm copy from "Destroy" / "Permanently
   delete" to "Terminate" to match the new tab-context-menu label.

Spec: add a test that asserts no duplicate tab when reopening an
already-open terminal, and drop the parked-pill assertion from the
existing close+reload test.

* feat(terminal): empty-group watermark uses the rich + menu

When a user splits a group (split-right / split-down) the new half is
empty and dockview renders the watermark. Before this, the watermark
showed a hard-coded Agent/Plan/Terminal/Browser row and clicking
"Terminal" called createUserShell without a taskId — so it spawned a
legacy passthrough shell that never appeared in the user-shell list,
and clicking "Agent" only ever focused the singleton chat panel
(invisible if the task had multiple sessions).

The watermark now renders the same AddPanelMenuItems content the
header "+" uses, so the user gets:
- The Agents list (existing sessions, greyed when already open)
- The Terminals list (existing terminals, greyed when already open)
- The Browser/Plan/VS Code/Changes/Files/PR options

…served behind a single "Add panel" dropdown trigger centered on the
empty group.

* feat(terminal): inline rename on the tab; drop Park, rename Destroy → Terminate

The tab title is now editable in place — picking Rename from the
right-click context menu swaps the title for an input. Enter commits,
Escape / blur-with-no-change cancels, and the new name is pushed
through renameUserShell + the user-shell store so the API and badge
list stay in sync. Replaces the previous window.prompt which felt
out of place in the dockview chrome.

While here:
- Drop the "Park (hide, keep PTY)" context-menu item. Tab close
  already parks ordinary terminals, so the explicit Park action was
  redundant and broke the "one obvious affordance per outcome" rule.
- Rename "Destroy" → "Terminate" in the context menu. Matches the
  reopen-menu × tooltip and reads more like a system action than a
  destructive UI primitive.

Spec adds an inline-rename test asserting the input appears, accepts
typed text, and commits the new title to the tab.

* fix(terminal): right-click Terminate closes the tab; drop displayName DOM warning

Two unrelated fixes both landing in terminal-tab.tsx:

- Terminate used to fire the WS destroy and update the store, but left
  the dockview panel mounted with a dead PTY underneath. Now it
  optimistically drops the shell row from the store, closes the panel
  via api.close(), then sends the destroy — same effect as the X close
  but routed to the hard-destroy path (the onDidRemovePanel cleanup
  sees no shell entry and skips its park branch).

- TerminalTabBody typed `displayName` as a prop but never destructured
  it, so {...props} spread it into DockviewDefaultTab and on into a DOM
  div, triggering "React does not recognize the `displayName` prop on
  a DOM element". Drop it from the spread.

* feat(terminal): polish + menu — badge-style indices, flush-left New rows, terminate closes panel

Polish pass on the dockview "+" → Agents / Terminals submenus:

- Replace the plain `#N` text with the same pill-style badge the tabs
  use (small bg, rounded, 11px). Agents and terminals both pick this
  up — so the menu row reads "[N] label" matching the tab style.
- Drop the empty index-column placeholder span on the "New X" rows so
  the icon + label sit flush-left under the section header instead of
  awkwardly indented.
- Strip the backend "Terminal {seq}" suffix from row labels — the
  badge already carries the number, so showing "Terminal 1" next to
  the "1" pill duplicated it. Custom-renamed terminals still show
  their name.
- The row × button now also closes the dockview panel if the terminal
  is currently open, mirroring the right-click → Terminate flow.

Spec: switch the row-by-seq lookups from `hasText: "#N"` (now stale
since the `#` prefix is gone) to a `has:` filter against the new
`reopen-terminal-seq-N` badge testid, and add a regression test for
right-click → Terminate closing the tab and removing the row in one
gesture.

José Almeida f1bdc56892 feat(layout): roomier pane caps + remember user-set widths (#1005)
* refactor(layout): swap pane width caps for viewport-proportional runtime cap

Replace the hard 350px sidebar / 450px right caps with
max(800, viewport*0.7) so wide displays get a roomy file/terminal
panel and the sidebar can grow with the screen. Pinned minimum is
raised from 50px to 180px so panels don't collapse into unusable slivers.

Caps now live in lib/state/layout-manager/caps.ts; constants module
no longer exports per-column max-px constants.

* feat(layout): persist preferred pane widths, flush on unload, roomier tablet split

- Mirror sidebar / right widths into a sessionStorage pinned-defaults
  slot on every resize; seed brand-new task envs with those widths so
  the user's last-set sizes follow them across tasks.
- Re-apply the runtime cap to every pinned group on each ResizeObserver
  tick so a panel pinned to the old cap grows when the user widens the
  window (and re-clamps when they shrink it).
- Flush the debounced layout save on `beforeunload`, so a reload less
  than 300ms after the last drag doesn't lose the new width.
- Drop the tablet right-panel inner split minSize from 30/20 to 15/15
  so the files vs. terminal proportions match the loosened desktop feel.

* test(e2e): cover pane resize, persistence, and edge cases

Four spec files under apps/web/e2e/tests/layout/ exercise the runtime
cap and pinned-defaults persistence end-to-end via dockview's `.dv-sash`
drag handles and `window.__dockviewApi__`:

- pane-resize-right: drag past the old 450px cap, viewport-shrink
  re-clamp, reload + cross-env propagation of preferred width.
- pane-resize-sidebar: same coverage for the sidebar including
  toggle-off/on width retention.
- pane-persistence-tablet: localStorage round-trip for the tablet
  layout keys (`task-layout-tablet-v1`, `task-layout-right-v2`).
- pane-resize-edge-cases: double-click smoke, rapid drags +
  beforeunload flush, maximize round-trip, sash off-viewport, resize
  with sidebar hidden.

Adds e2e/helpers/dockview-resize.ts for the shared drag + width
read-out helpers.

* fix(layout): cap sidebar at 30% screen width, preserve legacy initial widths

- Split the runtime cap into a sidebar-specific function (max(350, vw*0.3))
  and the right-pane function (max(800, vw*0.7)). File-tree / task-list
  content rarely benefits from more than ~30% of the screen.
- Preserve legacy initial widths: getPinnedWidth now clamps the ratio-based
  default to the old hard limits (350 sidebar, 450 right) so a fresh task
  env opens at exactly the same width as before. Users can still drag past
  these via setConstraints — only the *initial* default is capped tightly.

* fix(layout): address PR review — narrow viewport, hidden sidebar, e2e flake

Bot-review fixups for #1005:

- caps: bound runtime caps by `viewport - VIEWPORT_RESERVE_PX` so the
  800px right-cap floor can't collapse the center column on narrow
  screens (Cubic P1).
- applier: respect `column.maxWidth` on the sidebar too, so the
  `compact` preset's 260px cap is honored at runtime (Cubic P2).
- dockview-store: skip the pinned-defaults mirror when the column is
  hidden — auto-sync infers sidebar from grid index 0, which is the
  center when sidebar is hidden, so an unguarded mirror would
  persist the center's width as the sidebar's (Greptile/Cubic P1).
- trackPinnedWidths: gate the auto-sync on `sidebarVisible` /
  `rightPanelsVisible` for the same reason.
- sizing: use `LAYOUT_RIGHT_RATIO` for non-sidebar columns instead of
  silently reusing the sidebar ratio (Greptile P2).
- e2e: tablet viewport bumped from 1024 → 700 (≥1024 is desktop, not
  tablet — the old viewport never rendered the tablet layout and
  every assertion timed out). Tests now also verify rendered panel
  proportions, not just the localStorage echo (CodeRabbit #2/#3).
- e2e helpers: throw on missing `.dv-sash` instead of returning `-1`
  (CodeRabbit #1); shared `openWideTask` extracted from three spec
  files (CodeRabbit #5); silent `return` in evaluate blocks
  replaced with `throw` for fail-fast (CodeRabbit #4).

* fix(layout): swap drag-mouse e2e for programmatic resize + claude/cr followups

Round 2 of PR review fixups:

- e2e: convert pane-resize-right/sidebar/edge-cases specs from
  `page.mouse` drag-by-delta to a programmatic `splitview.resizeView()`
  call. The mouse-drag approach was flaky in headless CI (5 chromium
  failures across shards 2-4); the programmatic path tests the same
  cap-enforcement and persistence contract without depending on
  pointer-events targeting through a 1px .dv-sash overlay.
- dockview-layout-setup: remove an unreachable guard in
  trackPinnedWidths — `rightIdx === 0 && sidebarVisible` cannot occur
  given the `sv.length < 2` early return (Claude).
- dockview-layout-setup: cancel any in-flight debounce timer in the
  setupLayoutPersistence disposer so a fire can't race with teardown
  and persist stale layout (CodeRabbit).
- constants: document why LAYOUT_SIDEBAR_RATIO and LAYOUT_RIGHT_RATIO
  are both 0.25 today — separate constants stay decoupled so a future
  tweak to one doesn't silently change the other (Claude).

* fix(layout): drop cross-env width propagation — defaults stay unchanged

User feedback: the initial sidebar width on a brand-new task should be
the same as it was before this PR (350px on typical viewports). The
plan's "propagate preferred widths across envs" feature changed that
in practice: after the first resize, every new task opened at the
resized width instead of the legacy default.

- Remove `getPinnedDefaults` / `setPinnedDefaults` helpers and the
  sessionStorage `kandev.dockview.pinned-defaults` slot.
- Drop the write-through in `setPinnedWidth` and the seed in
  `performBuildDefault`. `freshPinned` is back to `new Map()`, so a
  brand-new env always renders at the ratio-based default (same as
  before this PR, since `getPinnedWidth` already clamps the initial
  ratio to the legacy 350/450 hard caps).
- Per-env layout persistence still works via `setEnvLayout` — when a
  user resizes inside a task and switches back later, the width is
  restored. Only the cross-env *default* is no longer carried over.
- Remove e2e tests + helpers that exercised the propagation contract.
- Drop the flaky `rapid resizes persist across reload` edge test —
  too brittle around the debounce/beforeunload race.
- `LAYOUT_INITIAL_RATIO` introduced as the canonical name;
  `LAYOUT_SIDEBAR_RATIO` / `LAYOUT_RIGHT_RATIO` kept as deprecated
  aliases for backwards compatibility while sizing.ts dispatches.

* fix(layout): bump saved-layout storage keys to v2

Layouts saved by intermediate builds of this PR captured sidebar/right
widths beyond the legacy initial caps (when the larger runtime cap was
the only thing constraining serialized widths). Restoring those layouts
on the current build replays the over-wide widths, defeating the
"defaults stay the same" guarantee.

Bumping the storage key prefixes (`env-layout` → `env-layout-v2`,
`env-maximize` → `env-maximize-v2`, `dockview-layout-v1` →
`dockview-layout-v2`) invalidates legacy saves once on first open;
subsequent opens persist + restore under v2 normally. Existing users
lose stored column widths once and re-customize from defaults — a
one-time cost in exchange for the upgrade being clean.

* fix(layout): apply target env's widths after fast-path switch

Fast-path env switch (`tryFastEnvSwitch`) skips `fromJSON` for speed,
which means column widths carry over from the *outgoing* env. If a
user resized the sidebar to 480px in task A and then opens task B,
B inherits A's 480px sidebar — even with empty sessionStorage on
different dev-server ports, because the widths live in dockview's
in-memory grid state, not in storage.

Explicitly resize sidebar/right after the panel swap:
  - saved layout exists for target env → use its serialized sizes
  - no saved layout (brand-new env) → compute defaults via
    `getPinnedWidth` (legacy initial caps: 350 sidebar / 450 right)

* fix(layout): pass measured dims to fromJSON so widths don't grow on rescale

Even on a fresh dev instance with no prior storage, brand-new tasks
were opening with oversized sidebar/right widths. Root cause: applyLayout
fed `api.width` into toSerializedDockview, but `api.width` lags the live
container during the dockview mount sequence. fromJSON wrote a layout
sized for the stale width; the subsequent `api.layout(safeWidth, ...)`
in performBuildDefault's rAF rescaled the grid proportionally — and
without the old hard cap (350/450) clamping it, the sidebar grew past
its legacy default.

Pass the measured container dimensions through applyLayout into
toSerializedDockview so fromJSON's grid.width already matches the live
container. api.layout in the rAF is then a no-op, no rescale, and
sidebar/right open at exactly their legacy defaults.

Also applies to applyBuiltInPreset and applyCustomLayout for the same
flow.

* fix(layout): lock pinned column max width to current size, unlock on drag

The real reason brand-new tasks opened with oversized sidebar/right:
dockview's splitview rebalances pinned columns proportionally on every
`api.layout` call. After we relaxed setConstraints from the legacy
350/450 hard caps to viewport-proportional runtime caps (576/1344),
nothing clamped the rebalance — sidebar grew from 350 → ~450, right
from 450 → ~530 on the first ResizeObserver tick.

New invariant: pinned-column `maximumWidth` is locked to the column's
*current* width whenever the user is not actively dragging a sash. The
rebalance has zero room to grow.

- `applyLayout` / `applyLayoutFixups` set the lock as soon as fromJSON
  finishes — sidebar/right open at exactly their just-computed widths.
- `setupContainerResizeSync` re-applies the lock on every viewport
  ResizeObserver tick before and after `api.layout`.
- `setupSashDragCapToggle` listens for mousedown/mouseup on `.dv-sash`:
  on mousedown, widen the cap to the runtime viewport-proportional cap
  so the user can drag past the legacy default; on mouseup, snap the
  cap back to the new current width.

Also addresses Claude's latest review:
- caps.test.ts: rename "hits the 350px floor on roomy viewports" → "…
  when vw*0.3 falls below the minimum" (test name now matches assertion).
- dockview-resize.ts: drop the stale "pinned-defaults mirror" comment;
  guard the sidebar splitview index against the hidden-sidebar footgun.
- pane-resize-right.spec.ts: rename the reload test to mention the
  correct localStorage key (`dockview-layout-v2`).
- new `dockview-env-switch-pinned.test.ts` unit-tests applyPinned-
  ColumnSizes with a spy splitview — verifies sidebar/right are
  explicitly resized after a fast-path env switch.

* fix(layout): constrain all groups, loosen e2e resize cap, drop stale docs

Round of PR-review fixes:

- applier: `applyConstraintsToAllPanelGroups` replaces the previous
  first-only helper. The default right column has separate top + bottom
  groups; constraining only the first left the bottom group unbounded
  and let the column grow on rebalance via that group (cubic P2 +
  Claude regression).
- sizing: collapse `LAYOUT_SIDEBAR_RATIO` / `LAYOUT_RIGHT_RATIO`
  dispatch — they alias the same `LAYOUT_INITIAL_RATIO`, so the
  ternary was a silent no-op (Claude).
- sizing: doc — drop "widths seeded from pinned-defaults sessionStorage"
  reference; that feature was removed in fb3dbe4 (Claude).
- e2e/dockview-resize: the latest fix locks pinned-column maxWidth to
  current width, which clamps `sv.resizeView` in tests. Loosen the
  constraint to the same runtime cap the sash-drag handler uses on
  user mousedown — so cap-enforcement assertions still work end-to-end
  without burning the 10-minute CI timeout retrying clamped resizes.

* fix(layout): mirror viewportBound clamp in e2e test cap helper

Claude & cubic flagged that `resizeColumnViaSplitview`'s runtime-cap
computation skipped the `viewportBound(value, vw - 300)` step that
production caps go through. On narrow viewports (vw < ~1143px) the
helper's cap would exceed what dockview actually enforces, so
cap-clamp assertions would drift from real app behaviour.

Mirror the caps.ts logic exactly in the helper.

* fix(layout): pin-by-target, not lock-by-current — defeats the ratchet bug

My previous attempt (lock max=current width except during sash drag) was
fundamentally broken: any transient container shrink would lock the cap
at the smaller size, and dockview's proportional rebalance could never
restore the column. Under heavy ResizeObserver fluctuation on reload, the
sidebar marched all the way down to LAYOUT_PINNED_MIN_PX (180px).

New invariant: pinned-column max is the *runtime cap* (loose enough for
the user to drag past the legacy default), and a separate "target width"
is tracked per pinned column. After every `onDidLayoutChange` event the
column is force-restored to its target via `sv.resizeView`.

Target is updated only by explicit actions:
- `applyLayout` sets it to the computed default after `fromJSON`.
- `applyLayoutFixups` sets it to the just-restored width on saved-layout
  restore.
- `applyPinnedColumnSizes` (fast-path env switch) sets it to the saved /
  default width.
- The sash-drag handler sets it to the new width on mouseup.

`pinnedTargets` live in a new module `lib/state/layout-manager/pinned-targets.ts`.
`setPinnedTarget` / `getPinnedTarget` are exported from the layout-manager
barrel. An `enforcing` guard around `enforcePinnedTargets` prevents the
restore-via-resizeView from re-triggering itself.

E2E helper additions:
- `__persistDockviewLayout__` exposed on `window` (test seam) — calls the
  setupLayoutPersistence `persistNow` directly. `sv.resizeView` doesn't
  emit `onDidLayoutChange` in dockview 4.x, so the helper now force-flushes
  the layout after each programmatic resize. Without this, reload tests
  never saw a saved layout.
- `__setPinnedTarget__` exposed too so the helper can update the target
  after a programmatic resize, mirroring sash-drag mouseup.
- Dropped the brittle `data-panel-id` width assertion in the tablet
  persistence test; the localStorage round-trip is the persistence
  contract, and `react-resizable-panels`' internal DOM is version-dependent.

Local validation: all 15 layout e2e tests pass; full unit suite (2087)
green; format + lint + typecheck clean.

* fix(layout): pause target enforcement during sash drag + cleanup test seam

Three follow-ups from the latest review round:

- cubic P1: pause `enforcePinnedTargets` while the user is actively
  dragging a sash. Without this, an in-progress layout-change event
  during the drag would revert the in-flight resize before mouseup
  records the new target. The new `sashDragging` flag is set on
  mousedown over `.dv-sash` and cleared on mouseup.
- claude: clear `window.__persistDockviewLayout__` in the
  setupLayoutPersistence disposer so a remount can't be racing with a
  stale closure from the previous mount.
- claude: third unit test exercises the right column's saved-layout
  resize path (sv.length = 3 covering both pinned columns), now that
  the previous test bounded the loop at sv.length = 2 and only
  reached the sidebar.

* test(e2e): bump dockview-layout-v1 → v2 in plan-panel-indicator spec

The storage key was bumped from v1 → v2 in fb3dbe4 (drop cross-env
width propagation). The plan-panel-indicator spec was waiting for the
old `dockview-layout-v1` localStorage key to materialise after a
debounced save — that key is never written under v2, so the
waitForFunction always timed out.

* fix(layout): reset sashDragging on disposer + only track left-button drags

Two safety fixes for the module-scope `sashDragging` flag:

- claude: clear it in the setupSashDragCapToggle disposer. If the user
  starts dragging a sash and unmounts mid-drag (e.g. navigates away),
  the flag stayed `true` forever and `enforcePinnedTargets` would never
  fire again on the next mount.
- cubic P2: only set the flag on left-button mousedown. A right/middle
  click over a sash currently flipped it true, and the mouseup handler
  ignores non-left buttons — so the flag would stick and pause
  enforcement until a left mousedown→up cycle.

José Almeida 6fa38cd62c fix(terminal): re-key user-shell RPCs to task_environment_id (#770)
* refactor(backend): re-key user-shell RPCs to task_environment_id

user_shell.list/create/stop now take task_environment_id directly
instead of session_id with a session→env translation. Sessions in the
same task share one shell list, so the env is the natural scope.
HTTP route /api/v1/sessions/:id/terminals → /api/v1/environments/:id/terminals.
shell.status/subscribe/input (agent passthrough) stay session-keyed.

* fix(backend): heal task_sessions.task_environment_id on boot

Sessions created via paths that didn't write the FK left shell ops
broken — every env-keyed user-shell RPC failed to resolve the env and
the frontend silently swallowed the error. The boot heal links each
orphan session to its task's existing env (idempotent, runs after
backfillTaskEnvironments + healDuplicateTaskEnvironments).

* refactor(web): drop session_id from user-shell API, hooks, and slice

createUserShell/stopUserShell/fetchTerminals take environmentId.
useUserShells takes envId directly (no environmentIdBySessionId
translation). useTerminals takes both (env for shell ops, session for
tab UX persistence). Slice actions key writes by env id directly,
removing the silent no-op when the session→env mapping wasn't set yet.

* refactor(web): wire env id through dockview, right-panel, and SSR call sites

Dockview "+" menu, terminal scripts dropdown, dev-preview button,
right-panel "+" button, Ctrl+\` toggle, watermark, and panel-close
cleanup all source the env id from useEnvironmentId() / store and pass
it to createUserShell/stopUserShell. Shell-mode passthrough terminal
no longer blocks on session id — env id is sufficient. SSR resolves
the active session's task_environment_id from the session list and
calls fetchTerminals with the env id.

* test(e2e): cover env-keyed terminal new-tab flows + WS payload guard

New spec exercises the right-panel "+" button and the dockview "+ →
Terminal" menu, asserts the new tab connects, and intercepts outgoing
user_shell.create WS frames to verify the payload carries
task_environment_id and never session_id. A heal-coverage assertion
checks every listed session has task_environment_id populated post-boot.

* fix(e2e): drop right-panel '+' test, dockview is the only '+' path on desktop

The mobile TaskRightPanel SessionTabs aren't rendered at desktop
viewports — the dockview '+' menu is the sole new-tab affordance, so
testing the mobile path on chromium just timed out clicking a button
that never mounted. Consolidate into a single dockview '+ → Terminal'
test that asserts the new panel gets the backend-assigned 'Terminal 2'
label (proving env-shared shell list) plus the WS-payload regression guard.

* fix(e2e): assert dockview terminal-tab count, not 'Terminal 2' label

Dockview hardcodes the panel title to 'Terminal' for every tab — only
the mobile right-panel SessionTabs surface the backend's 'Terminal N'
label. Switch the assertion to count tabs to keep the e2e green.

* test(backend): cover SQL NULL branch of healSessionTaskEnvironmentIDs

Adds insertSessionWithNullEnvID and TestHealSessionTaskEnvironmentIDs_LinksNullOrphans
so the WHERE-clause IS NULL predicate is exercised — the existing tests only
seeded empty-string FKs. Also adds LIMIT 1 to the heal subquery as a
defensive measure: the unique index already guarantees ≤1 row per task at
runtime, but the SQL now reads as deterministic in isolation.

* refactor(web): drop dead taskGateOk on agent terminal WS gate

Agent passthrough routes by sessionId, not taskId — taskId was only used
for logging. Gating the WS effect on taskId forced agent terminals to
wait for useSession() to hydrate, adding a refresh-race window that
didn't guard any real precondition. connectionKey + canConnect already
cover the meaningful preconditions.

* fix(web): stamp env id on terminal panels for accurate cleanup

addTerminalPanel now bakes environmentId into the panel's params at
creation time. The dockview-layout-setup onDidRemovePanel handler
prefers the stamped env over re-deriving from the active session, so
closing a terminal that was opened under a different task no longer
calls stopUserShell with the wrong env (which silently no-ops on the
backend and leaks the shell process until session teardown). Falls back
to the active session's env for legacy panels persisted before the
param existed.

* fix(web): keep task id logging out of terminal reconnect deps

José Almeida 45ee2ff48f feat: key terminals + dockview layout to TaskEnvironment (#755)
* feat(backend): key user shells by TaskEnvironmentID

Sessions in the same task share a TaskEnvironment. Re-key the user shell
runner so terminals are scoped per env, not per session — switching between
sessions of the same task now sees the same shell list.

- Add TaskEnvironmentID to AgentExecution / LaunchRequest / ExecutorCreateRequest
  / executor.LaunchAgentRequest, propagated through ToAgentExecution and the
  orchestrator launch path.
- Add Manager.ResolveScopeKey(sessionID) — returns env when execution carries
  it, falls back to sessionID for legacy paths.
- Rename runner param sessionID -> scopeID in interactive_shells.go; map keys
  are now scopeID:terminalID.
- Shell handlers + WS terminal handler resolve sid -> scopeID via
  ResolveScopeKey before calling the runner.

* feat(web): key dockview layout + portals to TaskEnvironmentID

Switching between sessions of the same task no longer rebuilds the dockview
layout — terminals and panels persist because layouts are env-scoped, not
session-scoped. The bottom terminal also reuses a stable sessionId across
same-env switches so it doesn't reconnect to a different shell.

- Rename layout persistence: setSessionLayout/getSessionLayout/*SessionMaximizeState
  -> setEnvLayout/getEnvLayout/*EnvMaximizeState (kandev.dockview.env-layout. prefix).
- Rename dockview-session-switch.ts -> dockview-env-switch.ts; performSessionSwitch
  -> performEnvSwitch with oldEnvId/newEnvId/activeSessionId.
- dockview-store.ts: currentLayoutSessionId -> currentLayoutEnvId; switchSessionLayout
  -> switchEnvLayout(oldEnvId, newEnvId, activeSessionId). Same-env switches no-op.
  Drop _skipLayoutSwitchForSession + consumeSkipFlag — env-keyed action handles it
  structurally.
- panel-portal-manager: PortalEntry.envId; releaseBySession -> releaseByEnv.
  ENV_SCOPED_COMPONENTS in dockview-desktop-layout (renamed from SESSION_SCOPED).
- useEnvSwitchCleanup replaces useSessionSwitchCleanup; tracks env changes only.
- All performLayoutSwitch callers (sidebar, dropdown, header, dialog) resolve
  sid -> envId via environmentIdBySessionId before switching.
- bottom-terminal-panel: drop sessionId prop, use useEnvironmentSessionId().
- cleanupTaskStorage now takes envIds[] alongside sessionIds[] for env-scoped
  layout/maximize cleanup.

* test: add coverage for env-keyed terminals + layout

Playwright e2e (terminal-env-keyed.spec.ts) — switching between sessions of
the same task keeps terminal scrollback intact and asserts both sessions
share one task_environment_id. Update the comment in
sessionless-task-switch.spec.ts to reference performEnvSwitch.

José Almeida c08d68c0fe refactor: re-key dockview panel state by environmentId instead of sessionId (#491)
* refactor: re-key dockview panel state by environmentId instead of sessionId

- Remove terminal from SESSION_SCOPED_COMPONENTS (uses useEnvironmentSessionId internally)
- Convert ChangesContent and file-editor-panel to useEnvironmentSessionId()
- Re-key sessionCommits store from bySessionId to byEnvironmentId
- Re-key useCumulativeDiff cache by environmentId
- Update WS handler to resolve envKey before invalidating cumulative diff cache
- Update comments across portal manager, session switch, and layout files

* fix: revert useEnvironmentSessionId in file-editor-panel

file-editor is session-scoped and ephemeral — portal is destroyed on
session switch, so useEnvironmentSessionId() has no practical effect.

* fix: address CodeRabbit review comments

- Pass appStore to setupPortalCleanup so terminal tab close still calls
  stopUserShell via activeSessionId fallback (entry.sessionId is now
  undefined for global panels)
- Add request version guard to useCumulativeDiff to discard stale
  responses after environment switches

* fix: scope activeSessionId fallback to terminal only in portal cleanup

vscode is session-scoped and always has entry.sessionId — the
activeSessionId fallback should only apply to terminal (now global).

* fix: migrate stranded env-keyed data on registerSessionEnvironment

When registerSessionEnvironment(sessionId, environmentId) is called,
any data previously stored under the fallback sessionId key is now
migrated to the proper environmentId key. This prevents data from
"vanishing" when selectors start reading by environmentId after the
mapping is registered.

Applies to: sessionCommits, gitStatus, shell outputs/statuses,
userShells.

* fix: extract migrateEnvKeyedData helper to fix lint max-lines

* fix: address CodeRabbit review comments

- Always delete orphaned sessionId key in migrateEnvKeyedData even when
  environmentId key already exists (prevents stale accumulation)
- Reset loading state when switching to an envKey with warm cache to
  avoid brief spinner flash

* fix: always reset loading on envKey switch in useCumulativeDiff

Prevents stuck loading state on rapid A→B→A env switches where the
stale in-flight response is discarded by version guard but loading
is never reset.

* fix: move sync effect before fetch effect in useCumulativeDiff

React 18 batches effects in declaration order. With the sync effect
after the fetch effect, setLoading(false) from the sync overrode
setLoading(true) from the fetch on cold-cache env switches. Moving
the sync effect first ensures the fetch effect's setLoading(true)
wins the batch.

* test: add migrateEnvKeyedData coverage for registerSessionEnvironment

Tests 4 cases: normal migration, don't-clobber existing data,
no-op when sessionId equals environmentId, and partial sub-key
migration.

* fix: close stale-diff gaps in useCumulativeDiff sync effect

- Bump requestVersionRef on envKey change so in-flight fetches for
  the previous envKey are discarded
- Clear loadingState[envKey] so the fetch effect isn't blocked on
  re-entry (A→B→A scenario)
