Run the terminal reaper once during startup.
When the host restarts after persisting disposeRequestedAt but before the daemon closes the session, startup calls only syncPortScans. The interval does not invoke run until REAP_INTERVAL_MS elapses, so the live daemon session can remain open for up to five minutes. Invoke the existing run once before starting the interval. This preserves the missing-session confirmation flow while closing live sessions with durable disposal intent promptly.

Translate the startup failure path through this message.
WorkspaceInitEffects.tsx still passes "Failed to create terminal" directly to toast.error. Non-English users therefore see English on terminal setup failures. Replace the raw string with the i18n lookup for this message.

Use the catalog’s creation-error wording.
Comparable creation-error messages use aanmaken, including Terminal session creation failed. Change this translation to Terminal aanmaken mislukt.

In `@apps/desktop/src/renderer/lib/terminal/terminal-runtime-registry.ts`:
- Around line 683-692: Update replaceEndedTerminal and prepareReplacement so the
ended terminal’s serialized history is captured before awaiting create(), or
otherwise keep the previous runtime protected from detach-triggered LRU eviction
until preparation finishes. Ensure preparation still sets the replacement
entry’s initialBuffer and the pane receives the preserved history even if
detach() occurs during asynchronous replacement.
In
`@apps/desktop/src/renderer/routes/_authenticated/_dashboard/v2-workspace/`$workspaceId/hooks/usePaneRegistry/components/TerminalPane/components/TerminalSessionDropdown/TerminalSessionDropdown.tsx:
- Line 234: Update the explicit terminal removal flow after
killTerminalSession.mutateAsync succeeds so it also clears the terminal from
workspaceRunTerminals via clearWorkspaceRunTerminal. Ensure this cleanup occurs
for the closePanesForTerminal path using intent "remove", while preserving the
existing onAfterRemove runtime-release behavior.
In `@packages/host-service/src/terminal/reaper/reaper.ts`:
- Line 210: Update the terminal disposal branch in sweepDefunct so each
successfully returned terminal ID also ends its terminal agent binding with
status "disposed" and the same endedAt timestamp, using
markTerminalAgentBindingEnded within the existing transaction. Preserve the
current terminalSessions update and return behavior.
In `@packages/host-service/src/trpc/router/terminal/terminal.ts`:
- Around line 315-325: Update createTerminalSessionInternal and killSession to
track pending terminal ownership in a registry alongside lifecycleOperations:
register the workspace after initial ownership checks and before the first
await, reject killSession when a pending owner exists for a different workspace,
and remove the registry entry during cleanup. Preserve tombstone insertion for
matching owners and creates with no pending registration.

- Around line 61-62: Update the pane-close loop in the Workspace component so

Preserve terminal history during asynchronous replacement. replaceEndedTerminal() awaits create() before prepareReplacement(). During this wait, TerminalPane can call detach(), which parks the ended runtime and schedules LRU eviction. If the parked-runtime cap is exceeded, eviction can dispose that runtime. prepareReplacement() then returns without setting initialBuffer, while the pane still switches to the replacement terminal. Capture the history before awaiting create(), or retain the previous runtime until preparation completes.

Bind pending terminal IDs to their create workspace. killSession inserts a disposed tombstone with the supplied workspace when no row exists. createTerminalSessionInternal creates its row only after daemon.open, so the tombstone can cancel an in-flight create from another workspace.
Add a pending-ownership registry beside lifecycleOperations. Register the workspace after initial ownership checks and before the first await. In killSession, reject a mismatched pending owner before inserting the tombstone. Remove the registry entry in cleanup. Preserve tombstone creation for matching and not-yet-started creates.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Isolate failures for each closed pane.
If one onAfterClose callback throws, the exception exits this loop. The store catches it only after the remaining panes are skipped. A multi-pane tab closure can therefore omit shutdown callbacks for later panes.
Catch errors inside the loop so each pane receives its callback.
Proposed fix

- registry[pane.kind]?.onAfterClose?.(pane, panes);

* docs: update weekly product documentation for September 23 Source of truth: live Notion SOP https://www.notion.so/3b3b9d5bf616810dbacaca7dd2305259 Window: GitHub merged:>=2026-09-16, through this run on 2026-09-23. gh returned 103 PRs (limit 1000, avoiding the SOP example’s 50-PR truncation). Workspace baseline: 2158895. Prior session stopped at a usage limit; the checkout was clean. ## Changes - Pages, CLI, and MCP: public sharing, workspace menus, origin labels, pagination, first-publish opening, version previews, mobile comments, and link handling: #7570, #7658, #7726, #7472, #7532, #7718. Files: pages.mdx; cli/cli-reference.mdx; mcp-server.mdx. - iPhone launch, requirements, setup, host states, and Pro checklist: #7703, #7686, #7697, #7661, #7642, #7494. Files: install.mdx; faq.mdx; overview.mdx; remote-access.mdx. - Editor save conflicts and Markdown link actions: #7711, #7621.

Files: first-workspace.mdx; workspaces.mdx. - Slack plugin tools and gated thread follow-ups, queuing, mute and stop controls: #7583, #7585, #7586, #7588, #7592, #7594. Files: use-with-slack.mdx. - New CLI transcript, environment, and page deletion commands; connected-service plugins and MCP CLI migration: #7602, #7317. Files: cli/cli-reference.mdx; skills.mdx. - Startup recovery and pre-account workspace migration: #7764, #7649. Files: troubleshooting.mdx. Current source wins over PR descriptions: page ordering is newest-created first, search includes description, default CLI output remains a bare array, and the leaderboard automatically backfills since launch (there is no history-range picker). Slack thread commands and Mobile settings retain their availability qualifications. No assumption that every merged fix is already in the latest download. ## Deliberately skipped - [#7765](#7765) fix(host-service): report GitHub being unreachable as unavailable, not a 500: Reliability or visual fix restores expected behavior; no new workflow or necessary workaround to document. - [#7756](#7756) fix(pages): restore page.list's bare-array contract for released clients: Restores compatibility for released clients; checked the current listPaginated implementation when documenting #7726. - [#7749](#7749) fix(build): build every dist-types a filtered mobile typecheck needs: Internal build, tests, migration, developer tooling, or recovery plumbing; no new user-facing instructions. - [#7748](#7748) feat(mobile): refresh the App Store listing and load review creds from .env: Marketing/store copy, layout, or launch assets; no separate product-doc change.

What & why
A parked terminal could lose its recovery path when the reaper marked its absent PTY exited before reattachment. Ended panes then offered Reconnect against the same dead ID. Layout synchronization also treated a remote pane removal as another local kill command.
This change coordinates creation and disposal through one per-terminal queue, keeps missing sessions recoverable, and separates explicit pane-close commands from synchronized removal. Ended panes offer New shell, which creates a fresh session and preserves bounded history from the previous runtime.
No database migration. Explicit pane close retains existing termination semantics. This does not add distributed view leases or general pruning of adopted panes. If both cancellation kill attempts fail, the error propagates and a surviving shell remains manually discoverable under Background terminals.
Validation
Final multi-client verification: six new real host/PTY scenarios passed (shared input, disconnect/reconnect, explicit cross-client kill, stale-ID isolation, workspace ownership, phone visibility/sizing, and natural exit). Existing create/sequence suites: 25/26 passed; the legacy replay timeout passed an isolated rerun. This covers mobile's protocol, not the iPhone UI.
Final cleanup ensures killed panes are removed even if workspace-run bookkeeping throws; 352 renderer/recovery tests, desktop typecheck, Biome and diff checks passed locally.
710 focused tests pass: 244 host, 114 panes, 352 renderer/recovery. All three changed packages pass typecheck; repository lint and diff checks pass. Earlier terminal-router integration run: 9/9 passed.
Independent worker: two pending-ownership regressions failed before the fix; 19/19 real-daemon create-on-attach tests pass afterward. It also reviewed binding reconciliation and callback isolation without finding further issues.
Regression assertions reproduced callback short-circuiting, late history capture, and pending-disposal hydration/binding errors before their fixes.
CDP before/after: restored the original renderer implementation, held creation after the host response, switched tabs with the parked-runtime cap set to 1, and verified eviction of the ended runtime. Original code lost history; fixed code retained it and executed a command in the new shell. Screenshots visually inspected, numeric evidence agrees, zero captured renderer errors. Test UI interactions used actual mouse/keyboard input; cap adjustment and delayed response were controlled fault injection.
Earlier CDP coverage includes eight recovery cycles (exit codes 0/42), renderer reload, split-pane isolation, ten tab switches, create failure, duplicate clicks, cancellation during auto-adoption, and a lost response after a committed kill. Evidence is retained locally because screenshots contain unrelated workspace names.
Latest full native terminal run: 77/80 passed. Two disposal-related failures coincided with daemon process-inspection failures under concurrent load; both passed serial reruns. The remaining empty-input BAD_REQUEST assertion also failed with the original implementation. Full native-suite success is not claimed.
Broad host runs previously stalled in native filesystem-watcher tests; full monorepo success is not claimed. Multi-window behavior has unit coverage but was not exercised through CDP.
