+# flashes). This MUST run on a disposable CI Windows: electron-builder's oneClick
+# installer uninstalls the registry-registered copy of the app before every
+# install, so running the harness on a machine with a real Orca install would
+# delete it. A fresh runner has no Orca registered, so it is the only safe home

+# To exercise this from the unmerged feature branch WITHOUT touching main, a

+/**
+ * Boots the BUILT terminal daemon (out/main/daemon-entry.js) under plain Node —
+ * the exact way production forks it (ELECTRON_RUN_AS_NODE = a plain-Node
+ * process) — and asserts it starts, serves a real PTY, and stops.
+ *
+ * Why this exists: native-smoke CI (and packaging) went green while
+ * v1.4.129-rc.1 shipped a daemon that exited code 1 at module load because an
+ * electron `require` leaked into its bundle graph. Nothing executed the built
+ * entry under plain Node, so the outage was invisible until an adopted old
+ * daemon died in the field. This runs on every PR that touches the daemon.
+ *
+ * Hard assertions (fail the job):
+ *   - the daemon signals `{ type: 'ready' }` over IPC within the timeout, and
+ *   - it terminates when asked (no hang / zombie).
+ * Best-effort (logged skip, never fails): an end-to-end `ptySpawnHealth` RPC,
+ * because node-pty spawn can be flaky on constrained CI runners.

The thumb stays invisible until the parent (`.scrollbar-sleek-parent`) is hovered. Used only in the worktree sidebar.

+# VS Code WSL Workspace Launch
+
+## Problem
+
+On Windows, choosing **Open in VS Code** for a workspace stored under a WSL UNC path opens the folder in a Windows VS Code environment instead of a Remote - WSL window ([issue #7649](https://github.com/stablyai/orca/issues/7649)). The renderer passes the workspace path and configured editor command unchanged (`src/renderer/src/components/sidebar/WorktreeOpenInMenu.tsx:103-121`), and the main process delegates launch argument construction to `resolveExternalEditorLaunchSpec` (`src/main/ipc/shell.ts:101-110`). The builder currently gives every non-Cursor executable only the original path (`src/main/external-editor-launch.ts:109-116`).
+
+The deterministic reproduction for `\\wsl.localhost\Ubuntu\home\aliuq\project` produces `code <UNC path>` with no remote authority. VS Code's supported Windows CLI form is `code --remote wsl+<distro> <Linux path>`.
+
+## Root cause
+
+`resolveExternalEditorLaunchSpec` does not distinguish a VS Code launch targeting a WSL UNC workspace. Orca already has a shared parser for both modern `\\wsl.localhost\...` and legacy `\\wsl$\...` paths (`src/shared/wsl-paths.ts:1-20`), but the editor launcher never uses it. VS Code therefore receives the Windows-visible UNC folder and correctly opens it as a local Windows workspace.
+
+## Non-goals
+
+- Change the Open in menu, settings UI, IPC payload, file-manager behavior, or SSH/remote-runtime behavior.
+- Infer WSL identity for ordinary drive-letter paths from project runtime settings.
+- Rewrite user-defined compound shell commands or add remote flags to Cursor, VSCodium, or arbitrary editors.
+- Install or configure the VS Code WSL extension.
+
+## Design
+
+1. In the external-editor launch-spec builder, parse the target path with the shared WSL UNC parser when the host platform is Windows.
+2. For direct/executable VS Code Stable or Insiders launchers only, reuse the existing normalized launcher-basename check and translate a recognized WSL target into `['--remote', 'wsl+<distro>', '<linuxPath>']`. The exact allowlist recognizes Stable's `code`, Insiders' `code-insiders`, and the direct `Code - Insiders.exe` basename without matching unrelated `code-*` editors. Matching is case-insensitive and strips every Windows launcher suffix already supported by Orca (`.cmd`, `.exe`, and `.bat`).
+3. Keep local paths, non-Windows hosts, non-VS-Code applications, and compound commands on their existing argument paths. The existing main-process spawn and Windows shim handling remain unchanged.
+4. Replace the temporary reproduction harness with focused regression cases in `src/main/external-editor-launch.test.ts` covering modern and legacy WSL UNC forms plus unaffected local/custom-editor behavior.
+
+## Data flow
+
+- Worktree menu selects VS Code and sends `(workspacePath, 'code')` over existing IPC.
+- Main process validates the absolute existing host path.
+- Launch-spec builder resolves the VS Code executable.
+- On Windows + WSL UNC + VS Code, the builder emits the Remote - WSL authority and Linux-native folder path.
+- Existing Windows spawn wrapping launches VS Code with those arguments.
+
+## Edge cases
+
+- Modern `\\wsl.localhost\<distro>\...` and legacy `\\wsl$\<distro>\...` paths both preserve the distro spelling and convert separators to a POSIX path.
+- Distro names and Linux folder paths containing spaces remain single arguments because launch-spec construction and Windows shim wrapping preserve argument-array boundaries.
+- A WSL distro root maps to `/`.
+- Windows drive-letter and ordinary UNC paths stay local.
+- macOS/Linux behavior stays unchanged even for strings that resemble WSL UNC paths.
+- Cursor retains `--new-window`; other custom editors retain their existing single path argument.
+- Compound commands remain user-owned and are not rewritten because inserting flags safely would require parsing arbitrary shell syntax.
+- SSH and remote-runtime workspaces remain blocked from local path opening by the existing renderer guard; this change does not alter that boundary.
+- If the VS Code WSL extension is unavailable, launch behavior is left to VS Code and Orca retains its existing spawn-success contract.
+
+## Test plan
+
+- Unit: demonstrate the pre-fix launch spec lacks `--remote` for a modern WSL UNC path.
+- Unit: assert the fixed modern UNC launch is `--remote`, `wsl+Ubuntu`, `/home/...`.
+- Unit: assert legacy `\\wsl$` and distro-root paths produce the same Remote - WSL form.
+- Unit: assert direct and resolved Windows VS Code Stable and Insiders launchers are matched case-insensitively across `.exe`, `.cmd`, and `.bat` suffixes.
+- Unit: assert distro names and Linux folder paths containing spaces remain intact arguments through launch-spec construction and Windows shim forwarding.
+- Unit: assert a Windows local path remains unchanged and explicit `darwin` and `linux` hosts do not acquire WSL remote arguments.
+- Unit: assert Cursor and another custom editor are not given VS Code remote arguments.
+- Integration/Electron: create a throwaway repo in the installed Ubuntu WSL distro, add/open it in Orca, choose Open in VS Code, and verify the VS Code remote indicator and an integrated-terminal Linux probe.
+- Adjacent smoke: open a local Windows workspace in VS Code and verify it remains a local Windows window.
+- Repository gates: focused Vitest files, `pnpm typecheck`, `pnpm lint`, and `pnpm check:max-lines-ratchet`.
+
+## UI quality bar
+
+Not UI-visible in Orca. The existing menu, labels, loading behavior, and errors do not change. The user-visible acceptance criterion is external: the launched VS Code window must identify the selected WSL distro and its terminal must run Linux.
+
+## Review screenshots
+
+1. Golden path: VS Code opened from a throwaway WSL workspace, showing the Remote - WSL indicator and a terminal Linux probe.
+2. Adjacent local path: VS Code opened from a local Windows workspace, showing a local Windows terminal/environment.
+
+## Rollout
+
+1. Add launch-spec regression tests and observe the WSL case fail against the desired arguments.
+2. Add the scoped VS Code + Windows + WSL argument translation.
+3. Run focused and repository-wide static/test gates.
+4. Validate WSL and local launches end to end, retaining local screenshots outside the PR.
+
+## Lightweight Eng Review
+
+- Scope: Kept to the launch-spec seam; no renderer, IPC, persistence, runtime-routing, or settings changes are needed because WSL filesystem identity is encoded in the UNC path.
+- Architecture/data flow: Reuse `parseWslUncPath` in the main-process pure argument builder, then leave executable resolution, Windows shim wrapping, spawn lifecycle, and renderer guards unchanged.
+- Failure modes covered:
+  - Modern and legacy WSL UNC aliases route to the correct distro and Linux path.
+  - Local/ordinary UNC paths and non-Windows platforms do not acquire remote flags.
+  - Case variants and supported Windows VS Code shim suffixes are recognized without classifying custom editors or compound shell commands as VS Code.
+  - Distro and folder names containing spaces survive the Windows shim as distinct arguments.
+  - Missing VS Code WSL support still follows the existing launch contract rather than adding a new partial-failure protocol.
+- Test coverage required:
+  - Pure launch-spec regression cases in `src/main/external-editor-launch.test.ts` for WSL aliases/root, launcher case/suffix variants, and unaffected branches.
+  - `src/main/ipc/shell.test.ts` plus the existing Windows shim contract to prove remote arguments, including spaces, are forwarded as distinct values.
+  - Live Windows + Ubuntu WSL + VS Code smoke for the actual environment boundary.
+- Performance/blast radius: One regex parse per external-editor click only; no startup, polling, watcher, terminal, or renderer cost. Blast radius is limited to direct VS Code launches of WSL UNC paths on Windows.
+- UI quality bar: Not UI-visible in Orca; VS Code must visibly attach to the requested WSL distro and run a Linux terminal.
+- Required review screenshots:
+  1. WSL VS Code window with distro indicator and Linux terminal probe.
+  2. Local Windows VS Code window demonstrating unchanged local launch behavior.
+- Residual risks: VS Code without the WSL extension may reject or prompt on the valid remote launch; this is external dependency behavior and should not cause Orca to fall back silently to the wrong Windows environment.

-# New Worktree Sidebar Reveal
-
-## Problem
-
-Issue https://github.com/stablyai/orca-internal/issues/350 asks that newly created worktrees jump into view in the left sidebar list with no scroll animation.
-
-Current behavior:
-
-- `activateAndRevealWorktree(...)` always calls `state.revealWorktreeInSidebar(worktreeId)` with no options.
-- `revealWorktreeInSidebar` defaults `behavior` to `'smooth'` (`ui.ts`).
-- `WorktreeList` forwards that behavior to `virtualizer.scrollToIndex(..., { behavior })`.
-
-Result: off-screen targets animate by default, including freshly created worktrees.
-
-## Root Cause
-
-`activateAndRevealWorktree` conflates two intents:
-
-1. activate existing worktree navigation (smooth reveal is fine);
-2. activate a just-created worktree (must jump immediately).
-
-Created-worktree callers cannot currently express reveal intent, so they inherit `'smooth'`.
-
-## Scope and Non-goals
-
-- Add an opt-in reveal behavior at activation call sites.
-- Apply `'auto'` only where the worktree is newly created/added in that flow.
-- Preserve existing behavior for normal worktree navigation (clicks, keyboard, history nav, palette selection of existing worktrees, port/status-driven activation) unless a caller opts in.
-- Do not change direct raw reveal paths in IPC handlers that intentionally call `store.revealWorktreeInSidebar(...)` outside `activateAndRevealWorktree` (terminal/editor/mobile focus paths remain smooth).
-- Do not change sorting/grouping/filter UI, list virtualization strategy, or sidebar styling.
-
-## Design
-
-1. Extend `activateAndRevealWorktree` options:
-   - `sidebarRevealBehavior?: PendingSidebarWorktreeReveal['behavior']`.
-2. In `activateAndRevealWorktree`, call:
-   - `state.revealWorktreeInSidebar(worktreeId, { behavior: opts.sidebarRevealBehavior })` when provided;
-   - otherwise keep `state.revealWorktreeInSidebar(worktreeId)` so default behavior stays unchanged.
-3. Pass `sidebarRevealBehavior: 'auto'` only from created/added-worktree flows:
-   - `useComposerState` full-create path;
-   - `useComposerState` quick-create path;
-   - `useIpcEvents` `onActivateWorktree` only when the event corresponds to a newly created worktree;
-   - `launch-work-item-direct`;
-   - folder add/create flows that activate a newly-added synthetic folder worktree (`AddRepoCreateStep` folder branch, `NonGitFolderDialog`, and `repos` slice `addNonGitFolder` path).
-4. Keep existing navigation activations smooth, including:
-   - `AddRepoDialog` / `ProjectAddedDialog` “open primary worktree” actions (these can target pre-existing worktrees, not guaranteed newly created);
-   - all existing `activateAndRevealWorktree(...)` callers that do not opt in.
-5. Keep `WorktreeList` reveal effect unchanged; it already honors `pendingRevealWorktree.behavior`.
-
-## Correctness Notes and Edge Cases
-
-- Repo-filter clearing remains unchanged: `activateAndRevealWorktree` only clears `filterRepoIds` when target repo is excluded.
-- Other visibility constraints are not auto-cleared. If the target exists but is hidden by other sidebar state, `resolvePendingSidebarReveal(...)` keeps the reveal pending.
-- The reveal effect uncollapses lineage/group containers before scroll; behavior changes only animation mode, not visibility resolution.
-- Pending reveal is a single store slot (`pendingRevealWorktree`). Concurrent reveal requests are last-writer-wins; this change should not alter that behavior.
-- If activation cannot resolve the worktree (`getKnownWorktreeById` miss), behavior remains unchanged (`false`, no reveal queued).
-- `ui:activateWorktree` is an overloaded IPC used by both creation and non-creation activation paths. The renderer must choose `'auto'` only for create cases (for example, worktree absent before fetch and present after fetch), and keep default smooth reveal for existing-worktree activations.
-- Multi-window consistency remains per renderer window store; each window applies its own reveal behavior locally.
-- This change is renderer-only; it does not add main-process coordination and does not make reveal ordering transactional across concurrent async creators.
-
-## Tests
-
-Add/adjust focused tests in `worktree-activation` coverage:
-
-- explicit `sidebarRevealBehavior: 'auto'` is forwarded to `revealWorktreeInSidebar(worktreeId, { behavior: 'auto' })`;
-- no option still calls `revealWorktreeInSidebar(worktreeId)` (store default remains smooth).
-
-Add call-site regression tests (recommended, small):
-
-- one composer create path passes `'auto'`;
-- one non-created navigation path stays default (no behavior option).
-
-## Rollout
-
-1. Add `sidebarRevealBehavior` option in `activateAndRevealWorktree`.
-2. Update created-worktree callers to pass `'auto'`.
-3. Add tests above.
-4. Run targeted Vitest tests, then `pnpm typecheck` and `pnpm lint`.
-5. Validate in Electron: with sidebar overflow, create a worktree and verify the list jumps to it without smooth animation.

+# Source Control Push Failure AI Recovery
+
+## Problem
+
+Push, force-push, publish, and sync push-stage failures flow through the shared
+remote operation formatter in `src/renderer/src/lib/source-control-remote-error.ts:94`
+and the editor-store toast paths in `src/renderer/src/store/slices/editor.ts:3716`
+and `src/renderer/src/store/slices/editor.ts:3821`. A local pre-push hook or
+lint hook is not an auth, protected-branch, or transport problem, so generic
+remote guidance sends the user in the wrong direction.
+
+PR #7787 proves the behavior is useful, but the prototype needs tightening before
+it is maintainable:
+
+- `src/renderer/src/components/right-sidebar/SourceControl.tsx:1938` and
+  `src/renderer/src/components/right-sidebar/SourceControl.tsx:5799` repeat
+  push-failure predicates and feed live branch/file state into a prompt that says
+  "at failure time".
+- `src/renderer/src/components/right-sidebar/use-source-control-recovery-ai.ts:63`
+  imports push detection again instead of consuming one derived recovery model.
+- `src/renderer/src/components/right-sidebar/source-control-ai-commit-failure-launch.ts:24`
+  and `src/renderer/src/components/right-sidebar/source-control-ai-push-failure-launch.ts:24`
+  are copied launch flows with action-specific copy.
+- `src/shared/source-control-commit-failure-agent-command.ts:6` and
+  `src/shared/source-control-push-failure-agent-command.ts:6` are identical
+  command-template builders.
+- `src/renderer/src/components/right-sidebar/source-control-fix-split-button.tsx:21`
+  already contains a reusable split button, while `SourceControl.tsx:6415`
+  carries a second inline version.
+- `src/renderer/src/lib/source-control-remote-error.ts:148` currently treats
+  any `isSync` error as push-like for hook detection. `syncBranch` calls the
+  formatter for fetch, upstream-status, pull, and push failures, so the renderer
+  cannot prove a sync error came from the push stage without an explicit marker.
+- `src/renderer/src/components/right-sidebar/SourceControl.push-failure-recovery.test.ts:2`
+  imports prompt helpers through the large React module instead of shared prompt
+  modules.
+
+## Goal
+
+Add first-class recovery for pre-push hook failures without growing a parallel
+push-only subsystem:
+
+1. Toasts for push, force-push, publish, and sync push-stage failures say
+   "blocked" for detected pre-push or lint-hook output.
+2. Source Control shows a concise Push blocked panel with Details and AI Fix
+   only for a failure snapshot that is both push-like and hook-like.
+3. AI Fix launches the configured `fixPushFailure` Source Control action with a
+   safe, provider-neutral prompt.
+4. Commit-failure recovery and push-failure recovery share launch,
+   command-template, split-button, and dense error-panel primitives.
+
+## Non-goals
+
+- Do not fix server-side pre-receive hooks, hosted CI failures, or provider-side
+  protected-branch failures from this entry point.
+- Do not bypass hooks, add `--no-verify`, push from the launched agent, create a
+  PR, or assume GitHub-specific terminology.
+- Do not add app-wide persistence for this transient failure panel.
+- Do not redesign the Source Control panel or the Source Control AI settings
+  model.
+- Do not fold unrelated launch surfaces such as checks recovery into this change
+  unless a tiny shared helper is already needed for commit/push recovery.
+
+## Design
+
+1. Keep push-hook detection and prompt building in shared code.
+   - `src/shared/source-control-push-failure.ts` owns normalization, bounded
+     scanning, summary text, Details eligibility, prompt truncation, prompt
+     rules, and changed-file list bounding.
+   - Detection must stay conservative: explicit `pre-push`/`prepush`,
+     `hook declined to push`, hook-runner output in push context, or lint output
+     in push context. Auth, non-fast-forward, protected branch, pre-receive,
+     submodule, and generic transport failures stay on the existing remote-error
+     path.
+   - Keep the output scan bounded at 64 KiB and the prompt failure-output
+     section bounded. Also cap prompt file lines to a small constant with an
+     omitted-count line; do not rely on the git-status cap, which is far too high
+     for prompt context.
+
+2. Make remote-error formatting sync-stage aware.
+   - Extend `RemoteOperationErrorOptions` with an explicit push-stage flag for
+     sync, for example `isSyncPushStage`.
+   - Gate push-hook classification on `isPush`, `isForcePush`, `publish`, or
+     `isSyncPushStage`; do not use bare `isSync` as evidence of a push failure.
+   - In `syncBranch`, pass the push-stage flag only inside the two inner
+     `pushRuntimeGit` catch blocks. The outer fetch, upstream-status, and pull
+     catches still pass `isSync` for Sync-shaped generic copy but must not render
+     blocked hook copy.
+   - Carry the same push-stage fact back to the renderer, either by tagging the
+     thrown `Error` with a narrow exported marker or by wrapping it in a typed
+     error that preserves the original message/cause. `SourceControl` must set
+     `syncPushStage` only from that marker, not from `kind === 'sync'` plus
+     hook-like stderr.
+   - Keep submodule push messages before hook detection so submodule guidance
+     remains more specific than AI recovery.
+
+3. Replace one-off command builders with one shared recovery command builder.
+   - Add a shared builder that accepts `{ actionId, promptOverride,
+     commandInputTemplate, basePrompt }` and renders the existing Source Control
+     AI command template for launch actions.
+   - Keep compatibility exports for commit and push helpers if nearby tests or
+     call sites still use those names, but make them wrappers over the generic
+     builder.
+   - Move prompt-builder tests to import from shared modules, not
+     `SourceControl.tsx`.
+
+4. Capture and derive push recovery state once.
+   - Extend `SourceControlActionError` with the raw error, a push-stage marker
+     for sync failures, the branch name at failure time, a bounded status-entry
+     snapshot at failure time, and a per-worktree sequence token.
+   - `runRemoteAction` clears the worktree's previous error and increments its
+     sequence before starting. A catch may write an error only if its sequence
+     still owns that worktree, so a slow failure cannot overwrite a newer retry
+     or success.
+   - Add a focused renderer helper that accepts the captured
+     `SourceControlActionError` and the current branch name, then returns either
+     `null` or a model with raw/sanitized detail text, summary, details flag,
+     kind label, and AI prompt.
+   - The helper returns `null` unless the operation is `push`, `force_push`,
+     `publish`, or `sync` with the sync push-stage marker and
+     `isPushHookFailure(rawError)` passes.
+   - If the current branch is known and differs from the captured branch, hide or
+     clear the model instead of launching an agent with wrong branch context.
+   - Pass that single model to `useSourceControlAi` and `CommitArea`; neither
+     prop construction nor `CommitArea` should repeat the push-hook predicate.
+
+5. Use one generic recovery launcher for commit and push failures.
+   - Replace the separate commit and push launch files with
+     `source-control-ai-recovery-launch.ts`, or keep the old files as one-line
+     wrappers if import stability is cheaper.
+   - The generic launcher owns connection resolution, SSH/local agent discovery,
+     saved-agent validation, agent-args validation, agent selection, terminal
+     launch, focus, and success/failure toasts.
+   - Resolve connection without collapsing local and unresolved states: read
+     `const worktreeConnectionId = getConnectionId(worktreeId)`, use it when it
+     is a string or `null`, and only fall back to `sourceRepoConnectionId` when
+     the worktree lookup returns `undefined`. If the fallback is also
+     `undefined`, show the workspace-connection error instead of launching
+     locally. `null` means proven local; a string means SSH/remote.
+   - Validate saved CLI args before agent detection or terminal creation. On
+     Windows, keep using PowerShell-safe planning through
+     `planAgentCliArgsSuffix(..., 'powershell')`.
+   - Action-specific data is limited to action id, base prompt, empty-prompt
+     copy, unavailable-agent copy, and success copy.
+
+6. Keep the recovery hook thin.
+   - `use-source-control-recovery-ai.ts` builds the commit prompt, accepts the
+     already-derived push recovery prompt/model, keeps independent loading
+     flags, and calls the generic launcher.
+   - It should not import push-hook detection, resolve agents, or duplicate
+     launch plumbing.
+
+7. Extract and reuse the recovery UI.
+   - Reuse or replace the existing
+     `src/renderer/src/components/right-sidebar/source-control-fix-split-button.tsx`
+     rather than adding another split-button component.
+   - Move the dense recovery notice and Details dialog into focused renderer
+     modules named for source-control recovery. Avoid `helpers`, `utils`, and new
+     max-lines suppressions.
+   - Reuse the same notice/dialog component for commit and push recovery with
+     action-specific labels, summary, details, prompt, saved recipe, and launch
+     callback.
+   - Keep normal remote errors filtered out when a push recovery model is
+     rendered, so the user does not see both Push blocked and generic remote
+     error copy for the same failure.
+
+8. Retain `fixPushFailure` in the existing Source Control AI action model.
+   - The prototype already adds `fixPushFailure` to
+     `src/shared/source-control-ai-actions.ts`; keep it as a launch action like
+     `fixCommitFailure`.
+   - Verify default settings, normalizers, global settings rows, repository
+     override rows, labels, descriptions, and variable chips all include Push
+     failure fixes.
+   - Do not create a push-specific settings store or migration. Existing
+     `normalizeSourceControlAiSettings` hydrates missing action defaults.
+
+## Data Flow
+
+- User clicks Push, Force Push, Publish Branch, or Sync.
+- `runRemoteAction` clears that worktree's previous remote error, records a new
+  sequence token, and starts the editor-store remote action.
+- Git push fails and throws.
+- `pushBranch` or sync's inner push-stage catch calls
+  `resolveRemoteOperationErrorMessage` with push-like options. Sync fetch, pull,
+  and upstream-status failures do not pass the push-stage flag.
+- Sync's inner push-stage catch marks the rethrown error as push-stage so
+  `runRemoteAction` can preserve `syncPushStage` in the captured snapshot.
+- The formatter classifies hook output before auth/transport fallbacks only for
+  push-like options and shows blocked toast copy.
+- `SourceControl` catches the same error, and if the sequence still owns the
+  worktree, stores `{ kind, rawError, message, syncPushStage, branchName,
+  entriesSnapshot }`.
+- The push recovery helper derives one `pushRecovery` model from that snapshot.
+- `CommitArea` renders normal remote errors or the Push blocked recovery notice.
+- AI Fix builds the `fixPushFailure` command input and launches the selected
+  agent in the owning local or SSH runtime.
+
+## Edge Cases
+
+- Auth, missing repo, protected-branch, pre-receive, non-fast-forward, and
+  transport failures must not show the Push blocked panel.
+- Submodule push errors keep their existing specialized messages before
+  push-hook detection.
+- Sync failures from fetch, upstream-status, or pull stages must not show Push
+  blocked, even if stderr contains words like "lint" or "hook".
+- Create PR intent remote failures use the same `runRemoteAction` plumbing; if
+  CommitArea is not visible, blocked toast copy is still required but no hidden
+  panel work is needed.
+- A newer remote operation for the same worktree must clear stale recovery state
+  immediately and prevent an older in-flight failure from writing after it.
+- Switching worktrees or branches must not show another worktree or branch's
+  push failure.
+- External edits or another Orca window may make the failure stale. Do not add
+  cross-window persistence for this feature; rely on local retry/remount/branch
+  mismatch clearing and list this as residual risk.
+- Source Control AI hidden for a repo still shows the blocked notice and Details;
+  it hides AI Fix.
+- SSH worktrees must detect and launch agents on the owning connection, not a
+  local fallback.
+- Windows launch planning must continue to use PowerShell-safe agent args.
+- Very large hook output and very large changed-file sets must be bounded before
+  prompt generation.
+- ANSI/control output must not leak into summaries or Details comparison logic.
+  Details may show sanitized text while preserving enough line breaks for
+  debugging.
+- Empty custom command templates must stay empty so the launcher rejects them
+  with a clear settings error.
+- Prompt text must treat file paths, branch names, and hook output as data, not
+  instructions.
+
+## Test Plan
+
+- Shared unit tests:
+  - `src/shared/source-control-push-failure.test.ts` covers detection positives,
+    auth/protected/pre-receive/non-fast-forward negatives, ANSI/control
+    stripping, bounded scanning, details comparison, prompt output truncation,
+    prompt file-list capping, and provider-neutral prompt rules.
+  - Shared command-template tests cover the generic recovery builder plus
+    commit/push wrappers, including empty templates and prompt overrides.
+  - `src/shared/source-control-ai-actions.test.ts` covers `fixPushFailure`
+    label, default template, variables, normalization, and action-list inclusion.
+- Remote formatter and store tests:
+  - `src/renderer/src/lib/source-control-remote-error.test.ts` covers push,
+    force-push, publish, and sync push-stage blocked copy plus sync non-push
+    stage negatives, auth/non-fast-forward/protected/pre-receive/submodule
+    regressions.
+  - `src/renderer/src/store/slices/editor.test.ts` covers the `pushBranch` toast
+    path and both sync push-stage and sync non-push-stage toasts.
+- Renderer model and UI tests:
+  - A focused push recovery derivation test covers operation kind, sync
+    push-stage marker, branch mismatch, stale sequence ownership, snapshot file
+    entries, summary, details flag, prompt contents, and ordinary remote errors.
+  - `CommitArea` tests cover the Push blocked notice, Details dialog, AI Fix
+    visible/hidden, ordinary remote errors, no duplicate remote error when a push
+    model exists, and unchanged commit-failure recovery rendering.
+  - Settings tests cover global and repository Source Control AI action rows
+    showing Push failure fixes.
+- Launcher tests:
+  - Generic recovery launcher tests cover commit and push action ids, invalid CLI
+    args before detection, empty template rejection, unavailable saved agent,
+    local versus SSH agent detection, successful launch/focus, and success copy.
+- Checks:
+  - Run targeted vitest files above, `pnpm typecheck`, `pnpm lint`, and
+    `pnpm check:max-lines-ratchet`.
+
+## UI Quality Bar
+
+The Source Control recovery UI must match `docs/STYLEGUIDE.md`: monochrome,
+quiet, dense, token-based, and consistent with adjacent commit-failure recovery.
+Use existing shadcn `Button`, `DropdownMenu`, and `Dialog` primitives, lucide
+icons, `card`/`border`/`destructive`/`muted` tokens, and the existing action
+recipe row patterns. The Push blocked notice should keep the summary readable at
+narrow right-sidebar widths, avoid nested cards, avoid new color values, show
+stable split-button geometry while launching, and keep Details as progressive
+disclosure for long hook output. Dialogs and dropdowns must remain usable in
+light/dark mode and under SSH latency.
+
+## Review Screenshots
+
+1. Source Control after a simulated pre-push hook failure: Push blocked notice
+   with summary, AI Fix, and Details.
+2. Push failure Details dialog showing hook output and Fix with AI.
+3. AI Fix customize-launch dialog for `fixPushFailure`.
+4. Ordinary push auth/protected/remote failure state: regular remote error, no
+   Push blocked notice.
+5. Sync fetch/pull-stage failure state: Sync-shaped remote error, no Push
+   blocked notice.
+6. Source Control AI hidden for the repo: Push blocked notice and Details, no AI
+   Fix.
+7. Source Control AI settings showing the Push failure fixes launch recipe.
+8. Adjacent commit-failure recovery notice still rendering correctly after the
+   shared UI extraction.
+
+## Rollout
+
+1. Tighten shared push-failure classifier/prompt bounds and add the generic
+   recovery command builder.
+2. Make remote formatter/store sync-stage aware and update toast tests.
+3. Add the `SourceControlActionError` snapshot/sequence data and one push
+   recovery derivation helper.
+4. Replace duplicated commit/push launchers with the generic recovery launcher
+   and thin hook wiring.
+5. Extract/reuse source-control recovery UI components, including the existing
+   split-button module.
+6. Verify `fixPushFailure` settings/default/normalizer coverage and i18n labels.
+7. Update targeted tests and run typecheck, lint, and max-lines ratchet.
+8. Validate rendered Electron states with screenshots before opening the PR.
+
+## Lightweight Eng Review
+
+- Scope: Reduced from PR #7787's push-specific parallel path to a shared
+  recovery layer. Keep the feature limited to local pre-push/lint-hook detection,
+  blocked copy, an inline recovery notice, Details, and AI launch. No persistence
+  or provider-specific recovery.
+- Architecture/data flow: Shared code owns classification, prompt text, and
+  command-template rendering; the editor store owns stage-aware toast formatting;
+  `SourceControl` owns transient worktree-scoped failure snapshots and sequence
+  invalidation; the generic launcher owns local/SSH agent discovery and terminal
+  launch.
+- Failure modes covered:
+  - Sync stage ambiguity: only the inner push stage may classify as hook-blocked.
+  - Auth/protected/pre-receive/non-fast-forward/submodule/transport errors stay
+    out of push recovery.
+  - Branch or worktree switches suppress stale recovery models.
+  - Per-worktree sequence tokens prevent older in-flight failures from
+    overwriting newer retries or successes.
+  - Empty custom templates, invalid CLI args, unavailable saved agents, missing
+    worktree context, SSH host detection, and Windows shell planning fail before
+    terminal launch.
+  - Large or hostile hook output and file lists are bounded and treated as data
+    in prompts.
+- Test coverage required:
+  - Shared classifier/prompt/command/action-model tests in `src/shared`.
+  - Remote formatter and editor-store tests for push, force-push, publish, sync
+    push-stage, and sync non-push-stage paths.
+  - Renderer derivation and `CommitArea` tests for Push blocked, Details, AI Fix,
+    hidden AI actions, stale branch/sequence, ordinary remote errors, and
+    existing commit failure recovery.
+  - Generic launcher tests for local/SSH, invalid args, saved-agent unavailable,
+    empty template, and success launch.
+  - Settings tests for global and repo Push failure fixes rows.
+  - Electron validation for all required screenshots; no separate E2E is
+    required if renderer tests cover the model and Electron validates the real UI.
+- Performance/blast radius: No polling, watchers, migrations, or startup work.
+  Runtime cost is one bounded classifier pass over at most 64 KiB, bounded prompt
+  output, and a bounded file snapshot only when a remote action fails. Largest
+  blast radius is the shared recovery UI and launcher used by existing commit
+  failures, so commit recovery needs tests and a screenshot.
+- UI quality bar: Match `docs/STYLEGUIDE.md` and adjacent Source Control density:
+  token-based error state, stable split-button geometry, progressive Details
+  disclosure, no nested cards, concise copy, light/dark compatibility, and
+  visible disabled/loading state under SSH latency.
+- Required review screenshots:
+  1. Push blocked notice after pre-push hook failure.
+  2. Push failure Details dialog with Fix with AI.
+  3. `fixPushFailure` customize-launch dialog.
+  4. Ordinary push auth/protected/remote failure with no Push blocked panel.
+  5. Sync non-push-stage failure with no Push blocked panel.
+  6. Source Control AI hidden: Push blocked without AI Fix.
+  7. Source Control AI settings showing Push failure fixes.
+  8. Existing commit-failure recovery notice after shared UI extraction.
+- Residual risks: Classifier false positives remain possible for unusual local
+  hook-runner output that mentions push context; keep tests biased toward
+  preserving auth, protected-branch, and non-fast-forward behavior. Failure
+  panels are renderer-local, so another Orca window or an external terminal can
+  fix the problem while the old panel remains visible until local retry, remount,
+  or branch/worktree change. Electron validation may need a mocked or temporary
+  repo scenario to trigger a real pre-push hook without mutating user data.

+# Prod Release Scan — output.md
+
+**Verdict:** ready with accepted P1 risk  
+**Span:** `v1.4.130` (`31378023`) .. `v1.4.131-rc.2` (`6964bfb23`)  
+**Planned release / RC:** `1.4.131-rc.2` (user asked for 1.4.132-rc2; that tag does not exist — scanned confirmed substitute)  
+**Included PRs:** 8 matched (+ `#7567` referenced only in `#7658` title, not a separate PR); unmatched commits: 5  
+**Batches reviewed:** 6 (agent/mobile, codex/speech/WSL, UI defaults, xplat/remoting, perf, security)  
+**Security model:** `codex --model gpt-5.6-sol -c model_reasoning_effort="xhigh"` (W6 + all workers)  
+**Orchestration:** 6 same-worktree tasks injected; `task-list`/`dispatch-show` verified

+## Issue table by PR / commit
+
+### Has issues
+
+| Ref | Title | Severity | Issue summary |
+|-----|-------|----------|---------------|
+| **#7906** | Wake slept agents when opening a worktree on mobile | **P1** (×3) | (1) Non-passive / manual-sleep wake on an **unmounted** worktree creates a tab with `activate:false` but never background-mounts → **no PTY / resume lost**. (2) Mounted manual-sleep can **double-resume** the same provider session (in-place wake + generic resume). (3) Edge-triggered wake can be **lost** if mobile opens during hibernation kill before `hibernatedWakePtyId` is armed. |
+| **#7906** | (perf composition) | **P1** | Passive completed wake background-mounts the **entire** worktree → O(all saved tabs) PTY/xterm work, defeating unvisited-worktree mass-spawn guard. |
+| **#7906** | (headless remoting) | **P1** | Wake is a no-op without a live renderer window; headless `orca serve --mobile-pairing` activates without waking slept agents. |
+| **#7960** | Write in-Codex setting changes back to `~/.codex` | **P1** (×2–3) | (1) Missing `~/.codex/` parent → `ENOENT` on promote, then mirror **wipes** runtime setting (test pre-creates dir and misses this). (2) `writeFileAtomically` without `mode` widens **0600 → 0644** on promote (reproduced). (3) Host-only promotion path: **WSL Codex never promotes** (WSL prep skips `syncSystemConfigIntoManagedCodexHome`). |
+| **#7658** | Recover WSL Codex usage RPC refresh | **P2** | Every WSL quota poll uses interactive login shell (`-ilc` + discovery chain); heavy rc cost on 15m poll / double on PTY fallback. |
+| **#7977** | Disable experimental new worktree card style by default | **P2** | Fresh default is correctly off, but cohort **auto-enabled in v1.4.130** stays on via persisted `true` (no rollback migration). |
+| **#7845** | Sidebar scrollbar only when overflow | **P2** (docs only) | Behavior OK; `docs/STYLEGUIDE.md` still says gutter is reserved — stale contract. |
+
+### No issues found (clean for this scan)
+
+| Ref | Title | Notes |
+|-----|-------|-------|
+| **#7860** | Separate pane identity from liveness (OMP tab flicker) | Identity vs liveness separation consistent across tab icon, PTY owner, web mirror; focused-pane owner re-owns Pi-compatible titles; no proven regression. |
+| **#7932** | Chunk offline audio decoding (ONNX SIGTRAP) | 30s chunk bound + quiet split; worker-side decode; pure chunker tests pass; no malware/native dep delta. Residual: no packaged ONNX runtime on all platforms. |
+| **#7933** | iOS native keyboard dictation in mobile terminal | Raw field echo; normalize only on send/mirror; no double-send proven. Mobile vitest not run (missing Expo deps in this worktree). |
+| `775fa956c` | Remove mobile driver overlay preview | Delete-only HTML mock. |
+| `8adfef4ff` | Update README downloads badge | `4.0m` → `4.1m` only. |
+| `ff661a7ab` / `41edc493b` / `6964bfb23` | release: v1.4.131-rc.{0,1,2} | Version bumps in `package.json` only. |

+
+## Findings first
+
+### P0 — Release Blocking
+
+None.
+
+No malware, backdoor, supply-chain implant, lockfile/dependency implant, install-hook change, or updater/signing bypass in this span.
+
+### P1 — Releasable Only With Explicit Acceptance
+
+1. **#7906 Mobile wake — unmounted non-passive sleep never gets a PTY**  
+   `wake-sleeping-agents-in-background.ts:43-56` only background-mounts for passive completed records; non-passive path creates inactive tab and clears the sleep record without a mounted `TerminalPane`.  
+   *Evidence:* `wake-sleeping-agents-in-background.ts`, `resume-sleeping-agent-session.ts:93-118`, `Terminal.tsx:729-778`.
+
+2. **#7906 Mobile wake — double resume of same provider session**  
+   Broadcast in-place wake then generic resume for non-passive mounted records before spawn clears the record.  
+   *Evidence:* `wake-sleeping-agents-in-background.ts:37-56`, `pty-connection.ts:6247-6255`, `resume-sleeping-agent-session.ts:279-315`.
+
+3. **#7906 Mobile wake — race during hibernation kill**  
+   Wake before `hibernatedWakePtyId` is armed is edge-triggered and not retried; passive path keeps record without launching.  
+   *Evidence:* `pty-connection.ts:2090-2169`, `orca-runtime.ts` fire-and-forget notifier.
+
+4. **#7906 Perf — whole-worktree background mount**  
+   One passive sleep record mounts every terminal tab in the worktree permanently.  
+   *Evidence:* `wake-sleeping-agents-in-background.ts:46-54`, `background-terminal-worktree-visibility.ts`, `Terminal.tsx` mount model.
+
+5. **#7906 Headless mobile pairing — wake no-op**  
+   No renderer ⇒ no wake; headless serve still returns activated.  
+   *Evidence:* `orca-runtime.ts:12627-12633`, `orca-runtime.test.ts` “deliberate non-goal”, `mobile/scripts/start-emulator-pairing-runtime.mjs`.
+
+6. **#7960 Missing `~/.codex` directory loses first promoted setting**  
+   Promote does not `mkdir` system home; `ENOENT` swallowed; mirror then clears runtime value. Test pre-creates `.codex` and misses the case.  
+   *Evidence:* `config-settings-promotion.ts:191-192`, `fs-utils.ts:6-14`, `config-settings-promotion.test.ts:190-191`. Reproduced: missing parent → `ENOENT`.
+
+7. **#7960 Permission widening on promote (privacy)**  
+   Atomic write without mode: `0600` → `0644` under umask `0022` (reproduced). Full user config becomes world-readable to co-tenants when parent dirs are traversable.  
+   *Evidence:* `config-settings-promotion.ts:191-192`, `fs-utils.ts:11-14`.
+
+8. **#7960 WSL never gets promotion**  
+   WSL launch/rate-limit prep returns after `syncWslRuntimeForCurrentSelection` and never calls host mirror/promotion. Feature is host-only.  
+   *Evidence:* `runtime-home-service.ts:139-150,225-235`.
+
+### P2 — Nice To Have
+
+- **#7658** Interactive login shell on every WSL rate-limit poll (`buildWslLoginShellCommand` / `-ilc`).  
+- **#7960** Unchanged baseline still rewritten twice per quota cycle; CRLF insert can mix EOL on new keys.  
+- **#7977** Auto-enabled experimental card cohort not rolled back.  
+- **#7845** STYLEGUIDE scrollbar gutter text out of date.
+
+---
+
+## Clean matrix
+
+| Area | Status |
+|------|--------|
+| Security / malware / supply-chain | **Clean of malice.** Lockfile unchanged; package scripts unchanged; version-only package.json. **P1 residual:** mode widen on `~/.codex/config.toml` promote. |
+| Performance / resource use | **P1** mobile whole-worktree mount; **P2** baseline double-write + WSL interactive poll cost. STT chunking is an improvement. |
+| macOS / Linux / Windows / WSL / PowerShell | **P1** WSL promotion gap; **P2** WSL interactive poll; CRLF insert. No new hard-coded Mac shortcuts. Real Win/WSL runtime not executed. |
+| Mobile / paired web / Electron | **P1** mobile wake correctness/composition gaps; #7860 / #7933 clean by source audit. |
+| Local / SSH / remote / VM / container | Wake path failures apply to local and SSH worktrees once host renderer is involved. Headless serve gap explicit. |
+| Git providers / shared contracts | Not materially touched. |
+| Release / package / update path | Version bumps only; no workflow/signing/native rebuild changes. |
+
+---
+
+## Verification
+
+| Check | Result |
+|-------|--------|
+| `git diff --check v1.4.130..v1.4.131-rc.2` | Passed |
+| Required security grep on non-lockfile span | 2 hits — both TOML `.exec` parsers in #7960; inspected, benign |
+| `package.json` / lockfile | Version field only; `pnpm-lock.yaml` no diff |
+| Mode repro (`writeFileSync` without mode) | `before 600` → `after 644` |
+| Missing parent repro | `ENOENT` |
+| Worker unit tests (various focused suites) | Reported green by workers (promotion, STT chunker, rate-limit, wake helpers, pane owner, etc.) |
+| Mobile Expo vitest / device / real WSL / ONNX packaged | **Not run** in this environment |
+
+---
+
+## Orchestration provenance
+
+| Worker | Task | Terminal | Report |
+|--------|------|----------|--------|
+| W1 agent/mobile | `task_20d8fd2460cc` | `term_40e66a33-…` | `reports/w1-agent-mobile.md` |
+| W2 codex/speech/WSL | `task_6e280ce1760e` | `term_59f3ead8-…` | `reports/w2-codex-speech-wsl.md` |
+| W3 UI/defaults | `task_7140cb2014c9` | `term_4e274a95-…` | `reports/w3-ui-defaults.md` |
+| W4 xplat/remoting | `task_424816ffe823` | `term_03c7aac8-…` | `reports/w4-xplat-remoting.md` |
+| W5 perf | `task_1c5ac42d7659` | `term_24778551-…` | `reports/w5-perf.md` |
+| W6 security | `task_bf5de6f4913a` | `term_ae19a68d-…` | `reports/w6-security.md` |
+
+All workers: `codex --model gpt-5.6-sol -c model_reasoning_effort="xhigh"`, same worktree, `--inject` dispatch.
+
+---
+
+## Residual risk
+
+- No runtime on physical iOS/Android, Windows+WSL2, or packaged sherpa/ONNX for all platforms.  
+- Lockfile/binary deltas fully inspected: **none**. Install hooks unchanged.  
+- #7906 integration of IPC wake × mounted/unmounted panes × async PTY exit is under-tested relative to risk.  
+- #7960 Windows ACL inheritance and concurrent external `~/.codex` edits not runtime-tested; POSIX mode widen is proven.
+
+---
+
+## Bottom line
+
+**No P0.** Multiple **P1**s cluster on **#7906 (mobile wake)** and **#7960 (Codex settings promotion)**. Ship only if product explicitly accepts those gaps, or fix before stable:
+
+1. Always background-mount (or otherwise attach) when creating a navigation-suppressed resume tab.  
+2. Deduplicate in-place hibernation wake vs generic resume for the same claim key.  
+3. `mkdir` system `~/.codex` before promote; pass `mode: 0o600` (or preserve existing mode) into `writeFileAtomically`.  
+4. Decide WSL + headless pairing product stance (implement promotion/wake or document as unsupported).
+
+Clean shippable areas for this span: **#7860**, **#7932**, **#7933**, release version commits, README badge, preview delete; **#7845** functionally clean with docs P2.

+ * Relocates the terminal daemon's process image out of the app install

+ *
+ * Why: the daemon is forked as plain Node via ELECTRON_RUN_AS_NODE, so its
+ * image is the install-dir Orca.exe and its loaded modules (node-pty native,
+ * ConPTY runtime) map from the install dir. On update, electron-builder's NSIS
+ * installer deletes the old install and force-closes every process whose image
+ * lives under it — killing the daemon and every live terminal it owns. Copying
+ * the daemon's whole file closure to a version-keyed userData dir and forking
+ * from that copy takes its image + loaded modules out of the installer's reach.
+ *
+ * The copy keeps the ELECTRON binary run as node (not stock node.exe): a copy
+ * of Orca.exe (renamed to a distinct image name) is byte-identical, so
+ * run-as-node behavior — no console flashing, asar-correct — matches the in-dir
+ * fork exactly. The win-unpacked layout is mirrored verbatim so
+ * require('node-pty') and node-pty's native loader resolve the relocated tree
+ * identically to the packaged app.
+ *
+ * Fail-open everywhere: any failure returns null and the caller forks the
+ * install-dir host — the pre-relocation behavior, byte-identical off win32.

+ * interactive fs.readDir/fs.stat requests past their 30s timeout. This
+ * coordinator guarantees at most one scan in flight per client:
+ *   - a request for the same root/excludes joins the in-flight scan
+ *     (Quick Open + file-explorer filter share one scan),
+ *   - a request for a different root supersedes it — the old scan is aborted
+ *     and its request fails fast instead of running to completion (this also
+ *     protects against older Orca clients that never send rpc.cancel),
+ *   - when every joined requester cancels (rpc.cancel / client detach), the
+ *     scan is aborted so abandoned work stops immediately.

+ * and only latches `_needsFullRefresh`, so the reveal-repaint's

+/**
+ * E2E regression test for the reattach mouse-mode leak fixed alongside #7329.
+ *
+ * Why this suite exists:
+ *   A TUI that armed mouse tracking (?1000/1002/1003 + SGR 1006/1016) and died
+ *   uncleanly never emits the disable sequence. The daemon's private-mode
+ *   tracker keeps the mode and buildRehydrateSequences re-arms it on every
+ *   reattach, but POST_REPLAY_REATTACH_RESET used to clear cursor/focus/kitty
+ *   state and NOT mouse modes. A plain shell in the reattached pane then echoed
+ *   every pointer-motion report (`<35;col;rowM`) as literal text.
+ *
+ * What it covers (full stack, no mocks):
+ *   - First launch arms the leak for real: a fixture writes the enable sequence
+ *     to stdout and exits, and the live pane is asserted to enter mouse-reporting
+ *     mode (the byte flow the daemon's tracker also records and re-arms).
+ *   - After a warm reattach, the renderer terminal ends with mouse reporting
+ *     DISARMED: mouseTrackingMode is 'none', the enable-mouse-events class is
+ *     gone, and real pointer motion produces zero mouse reports.
+ *   - A positive control re-arms the same modes and confirms the motion probe
+ *     does observe reports, so the "zero reports" assertion cannot pass vacuously.
+ *
+ * What it does NOT cover:
+ *   - That the daemon's buildRehydrateSequences re-arms the mode on reattach —
+ *     locked by repro-7329-remote-snapshot-corruption.test.ts against the real
+ *     serializer + xterm. This suite proves the reset half end to end.
+ *   - Live-agent panes keeping mouse via POST_REPLAY_LIVE_AGENT_REATTACH_RESET
+ *     (unit-tested in pty-connection.test.ts).

+ * Reproduction for the "missing bottom rows on reveal, recover on drag-select"

+ * its IntersectionObserver: while `_isPaused` is true (the observer can lag a
+ * frame behind a just-revealed pane, worse under load), refresh() early-returns
+ * and only latches `_needsFullRefresh`. The reveal-repaint's terminal.refresh()
+ * is then swallowed and the freshly-cleared render model never repaints.
+ *
+ * This spec drives the REAL production reveal path (manager.resetWebglTextureAtlases
+ * -> resetWebglTextureAtlas -> forceRepaintThroughRenderPause) against a real
+ * xterm Terminal + RenderService. It:
+ *   1. proves the bug: while paused, a plain refresh() renders nothing;
+ *   2. proves the fix: the real reveal repaint forces a full-viewport render
+ *      through the paused gate and clears the pause latch;
+ *   3. confirms recovery at the pixel level.
+ *
+ * The paused state is set deterministically rather than raced, because headless
+ * Electron does not reliably reproduce the observer-lag timing (documented for
+ * this bug class). The gate we force is the exact one the field bug hits.

+# daemon-relocation-spike
+
+A throwaway probe that answers one empirical question for Phase 1 of the
+Windows update-survival work:
+
+> What is the **minimal set of files** that must be copied out of a packaged
+> `win-unpacked` build so that a **copied `Orca.exe`** — run with
+> `ELECTRON_RUN_AS_NODE=1` from a directory **outside** the install dir — can:
+> (a) start the terminal daemon and signal ready over IPC,
+> (b) spawn a real ConPTY `node-pty` session, write input, and read output back,
+> (c) do all of that while holding **no open file handles into the app/install
+> dir**, so an NSIS update could delete the original install.
+
+## Why this matters
+
+The daemon is `fork()`ed from the app's own Electron binary (`Orca.exe`) with
+`ELECTRON_RUN_AS_NODE=1`, from the **install** directory. On a Windows update,
+electron-builder's NSIS installer (a) runs `uninstallOldVersion` (deletes the
+registered install's files) and (b) `CHECK_APP_RUNNING` force-closes every
+process whose image path is under `$INSTDIR`. So the daemon dies and its held
+file locks can break the update.
+
+The Phase 1 fix copies the daemon's whole file closure **out** of the install
+dir (into `%LOCALAPPDATA%`/userData) and forks the daemon from the **copy**, so
+its image + all loaded modules live outside `$INSTDIR`. This spike measures how
+small that copy can be while still working.
+
+We keep the **Electron binary run as node** (not a stock `node.exe`): a prior
+attempt (#7473, reverted) switched to stock node and caused Windows-console
+flashing (stock node lacks Electron's `kHideConsoleWindows`) plus asar breakage.
+This spike does **not** reintroduce stock node.
+
+## Usage
+
+```
+# Real run (Windows, needs a packaged win-unpacked build):
+node tools/daemon-relocation-spike/spike.mjs \
+  --app-dir <path-to-win-unpacked> \
+  --work-dir <scratch-dir> \
+  [--tier full|no-gpu|minimal] \
+  [--keep-work-dir]
+
+# Offline logic validation (any OS, no build, no launch):
+node tools/daemon-relocation-spike/spike.mjs --selftest
+```
+
+Exit code is `0` only when the run **PASSES**: daemon ready, PTY echo
+round-trips the nonce, the daemon's main module is the copied `Orca.exe`, and
+**no** loaded module resolves under `--app-dir`.
+
+## Tiers (defined as data in `tier-file-set.mjs`)
+
+Every tier includes the irreducible core: `Orca.exe`, `icudtl.dat`, both V8
+snapshot blobs (`snapshot_blob.bin`, `v8_context_snapshot.bin`), the daemon
+bundle (`out/main/daemon-entry.js` + `chunks/` + `out/package.json`), and the
+whole `node-pty` package (native `conpty.node` + the sibling `conpty/` runtime
+dir holding `conpty.dll` + `OpenConsole.exe`).
+
+Tiers differ only in which top-level `*.dll` files they carry:
+
+| Tier      | Top-level DLLs                                                    |
+| --------- | ---------------------------------------------------------------- |
+| `full`    | **all** top-level `*.dll`                                         |
+| `no-gpu`  | all **except** GPU/render DLLs (`libEGL`, `libGLESv2`, `vk_swiftshader`, `vulkan-1`, `d3dcompiler_47`); **keeps** `ffmpeg.dll` |
+| `minimal` | **none** (exe + data blobs + daemon bundle + node-pty only)      |
+
+Trimming further is a config change (edit `TIER_DEFINITIONS` / `GPU_DLLS`), not
+a code change.
+
+## How node-pty's native + ConPTY runtime is handled
+
+The whole `node-pty` package tree is copied, and **the entire win-unpacked
+layout is mirrored verbatim** (every copy destination is relative to the
+win-unpacked root, not the asar-unpacked root). This matters because node-pty is
+packaged at `resources/node_modules/node-pty` — a **sibling** of
+`app.asar.unpacked`, not under it (see
+`config/packaged-runtime-node-modules.cjs`). Mirroring the full layout preserves
+two resolutions from the relocated path:
+
+1. **The daemon require-closure** resolves `require('node-pty')` by walking
+   parent dirs up from the mirrored
+   `resources/app.asar.unpacked/out/main/daemon-entry.js`, which passes through
+   `resources/` and finds `resources/node_modules/node-pty` — exactly as in the
+   packaged app.
+2. **node-pty's own native loader** resolves `conpty.node` from `build/Release`
+   (or `prebuilds/win32-<arch>`) relative to node-pty's own `__dirname`, and
+   node-pty's Windows addon loads `conpty.dll` from `<dir-of-conpty.node>/conpty/`
+   and spawns `OpenConsole.exe` from beside it. Copying the tree verbatim keeps
+   all three side-by-side.
+
+### `ORCA_NODE_PTY_NATIVE_DIR`
+
+The reverted #7421 added a `node-pty` patch that reads
+`ORCA_NODE_PTY_NATIVE_DIR` to override the native dir. **The current branch's
+`config/patches/node-pty@1.1.0.patch` does NOT contain that override** — it was
+reverted. The spike therefore relies on **layout preservation** (copying the
+node-pty tree at its default relative path) rather than the env override. The
+spike still *sets* `ORCA_NODE_PTY_NATIVE_DIR` to the relocated native dir so it
+keeps working if pointed at a build that carries the patch, but on this branch
+the var is inert.
+
+**Implication for the real Phase 1 implementation:** if the production copy does
+NOT preserve node-pty at the path its loader resolves by default (e.g. if the
+daemon-entry is relocated without the sibling `node_modules/node-pty`), the impl
+will need to **re-add the `ORCA_NODE_PTY_NATIVE_DIR` patch** from #7421. If it
+mirrors the layout as this spike does, the patch is not strictly required —
+though re-adding it is the more robust choice.
+
+## The handshake / client
+
+`ndjson-client.mjs` is a small standalone NDJSON client (no electron/src
+imports) that mirrors `src/main/daemon/daemon-server.ts`:
+
+1. Read the token the server writes to the token file after it begins listening.
+2. Open a **control** socket, send `hello {role:'control'}`, await
+   `{type:'hello', ok:true}`.
+3. Open a **stream** socket with the **same** `clientId`, send
+   `hello {role:'stream'}`.
+4. `createOrAttach` on control, then `write` `echo SPIKE-OK-<nonce>\r\n`, and
+   read `data` events on the stream socket until the nonce appears **alone at
+   line start** (executed output, distinct from the echoed input line).
+
+`PROTOCOL_VERSION` is read at runtime from `src/main/daemon/types.ts` so the
+client never drifts from the daemon.
+
+## The handle probe
+
+`loaded-modules.ps1` (via `loaded-module-probe.mjs`) runs
+`Get-Process -Id <pid>` and enumerates `.Modules[].FileName`. Any module path
+under `--app-dir` is a **lock risk** (the installer cannot replace a file a live
+process maps), so a passing relocation must show **zero**. It also asserts the
+process's **main module** is the copied `Orca.exe`, not the install-dir one.
+
+Loaded DLLs are the lock-critical set. Data files (`icudtl.dat`, asar) are not
+memory-mapped as modules, so this probe does not enumerate them — the copy plan
+handles those by construction (they are copied, so nothing opens the originals).
+
+## What remains unverified until CI runs it
+
+This session has **no build**, so the launch path is unproven. Verified here:
+`node --check` on every `.mjs`, a green `--selftest`, and clean
+`pnpm exec oxlint`. Open questions the real CI run must answer:
+
+- Whether `TIER_MINIMAL` (no top-level DLLs) boots `Orca.exe` as node at all, or
+  whether run-as-node still needs `ffmpeg.dll` / others — this is the core
+  empirical result.
+- Whether the daemon bundle require-closure needs any **other** unpacked
+  `node_modules` beyond `node-pty` (surfaces as a ready-timeout if so).
+- Whether any loaded module still resolves under `--app-dir` (the handle probe
+  will name it).
+
+## Recommendation for the likely-minimal tier
+
+`no-gpu` is the safe minimal target to ship: run-as-node Electron does not
+initialize the GPU/render stack, so `libEGL` / `libGLESv2` / `vk_swiftshader` /
+`vulkan-1` / `d3dcompiler_47` are very unlikely to load, while `ffmpeg.dll` and
+the ICU/snapshot data are retained because the Electron bootstrap references
+them regardless of run-as-node. Run `--tier minimal` on CI first: if it PASSES,
+ship minimal; if `Orca.exe` fails to boot without the non-GPU DLLs, fall back to
+`no-gpu`. `full` is the always-works upper bound for comparison.

+# Repro harness: watcher.node main-process crash (issue #7547)
+
+Manual, Windows-focused harness for the `@parcel/watcher` native crash class
+(`0xc0000409` fail-fast / `0xc0000005` AV in `watcher.node`; same family as
+macOS #5377 and Linux #6635). Not run in CI — it deliberately crashes
+processes and hammers the filesystem.
+
+All watched/churned directories live under `os.tmpdir()`, never the repo.
+
+## Reproduce the bug (in-process watcher, pre-fix architecture)
+
+```
+node tools/repro-watcher-crash-7547/run.cjs delete-root 3 15000
+```
+
+Spawns `child.cjs`, which uses `@parcel/watcher` **in-process** the way
+`filesystem-watcher.ts` did before the fix. Scenarios (arg 1):
+
+- `delete-root` — subscribe to worktree-like dirs, churn files, delete the
+  watched root mid-churn, unsubscribe (worktree deletion during agent writes).
+  Crashes in seconds on Windows.
+- `unsub-churn` — rapid subscribe/unsubscribe cycles against live churn.
+  Also crashes: the trigger is `unsubscribe()` racing active event delivery
+  (`CancelIo` from the wrong thread leaves a pending `ReadDirectoryChangesW`
+  completion pointing at a freed `Subscription`).
+- `worker-mix` — worker_threads sharing the process-global native `Watcher`.
+- `del-nounsub` / `del-nochurn` / `del-1lane` — minimisation variants
+  (deletion without unsubscribe does NOT crash; unsubscribe is the trigger).
+- `overflow`, `mixed`.
+
+A native crash surfaces as the child's exit code (`0xC0000409` = 3221226505,
+`0xC0000005` = 3221225477) and the runner stops.
+
+## Verify the fix (out-of-process watcher)
+
+Build first so the forked entry exists, then run from the repo root:
+
+```
+npx electron-vite build
+node tools/repro-watcher-crash-7547/fixed-child.cjs 15000
+```
+
+`fixed-child.cjs` esbuild-bundles the real `src/main/ipc/parcel-watcher-process.ts`
+client and runs the same `delete-root` + `unsub-churn` load through the forked
+`out/main/parcel-watcher-process-entry.js`. Expected output: contained watcher
+process crashes (counted, recovered by respawn+resubscribe, surfaced through
+`onInterruption`), a final health check that sees live events, and exit 0.
+
+Exit codes: 0 pass · 5 watcher not functional at end · 6 in-process fallback
+used (isolation not exercised) · 7 watchdog · 8 premature exit.

+// Throwaway repro harness for issue #7547 — Windows main-process crash in
+// @parcel/watcher (watcher.node, 0xc0000409 fail-fast).
+//
+// Runs ONE scenario in THIS process (the parent runner spawns us in a loop and
+// watches our exit code). Each scenario mimics a real Orca usage pattern:
+//
+//   delete-root  — subscribe to worktree-like dirs, churn files, delete the
+//                  watched root mid-churn (worktree deletion during agent
+//                  writes). Exercises the WindowsBackend error path
+//                  (handleWatcherError -> Watcher::notifyError on the backend
+//                  thread).
+//   unsub-churn  — rapid subscribe/unsubscribe cycles on dirs with live churn
+//                  (worktree switching + 30s-grace teardown compressed).
+//                  Exercises pending-ReadDirectoryChangesW teardown.
+//   worker-mix   — worker_threads subscribe to the SAME dirs as the main env
+//                  (desktop explorer watch + runtime file-watcher worker on one
+//                  worktree). Workers exit cleanly, exit without unsubscribing,
+//                  or are terminate()d — then new workers subscribe again so
+//                  std::thread::id values recycle against the process-global
+//                  shared native Watcher.
+//   overflow     — one watched dir, massive delete/rename bursts with long
+//                  file names to force ERROR_NOTIFY_ENUM_DIR ("Buffer
+//                  overflow") on the backend thread.
+//   mixed        — all of the above concurrently.
+//
+// Exit code 0 = survived the scenario. A native crash surfaces as the child's
+// exit code (0xC0000409 = 3221226505) in the parent.

+# win-update-e2e — packaged NSIS update proof harness
+
+**Windows only.** Given two Orca Windows installers (version N and N+1), this
+harness performs a real silent update and proves, with machine-checkable
+assertions, what happens to the terminal **daemon** and its **sessions** across
+the update — and whether any console/terminal window flashes.
+
+It is the Phase 0 "proof harness" deliverable from
+[`docs/windows-terminal-update-survival-plan.md`](../../docs/windows-terminal-update-survival-plan.md).
+It exists specifically because the July 2026 attempt shipped four broken RCs
+without ever installing the packaged artifact (see
+[`docs/windows-terminal-update-survival-postmortem.md`](../../docs/windows-terminal-update-survival-postmortem.md),
+"Why verification missed every one of these"). Its design refuses to repeat
+those verification failures:
+
+- **Window visibility is measured by window enumeration + owner/canary
+  attribution — never by conhost command-line heuristics.** The post-mortem
+  proved conhost flags invert with parent console state and `MainWindowHandle`
+  is `0` for Windows-Terminal-hosted consoles. See `window-enum.ps1`.
+- **Interactivity is proven by execution, not by result-shape.** Typed commands
+  write sentinel **files**; the harness checks the files. A command that "runs
+  and returns correct output" but flashes a window is still caught, because the
+  window watch runs independently.
+- **The daemon is identified by command-line marker, never by exe name.** With
+  `ELECTRON_RUN_AS_NODE` the daemon image is `Orca.exe`; a relocated Phase 1
+  host may be a differently-named copied binary. See `daemon-processes.mjs`.
+- **Each run uses an isolated userData dir** so its daemon's socket/token path
+  is unique and never collides with the many other daemons a dev box or CI
+  runner can host.

+
+### Profiles
+
+- **`cold-restore`** — **today's** behavior and the baseline that must keep
+  passing against current `main`. The installer's path sweep kills the in-dir
+  daemon, so: old daemon PID is **dead**, a **fresh** daemon exists, scrollback
+  is cold-restored (best-effort), a new terminal is interactive, and **zero**
+  unexpected console/terminal windows appear.
+- **`survival`** — the Phase 1 target. Daemon PID **unchanged** across the
+  update, marker process **still alive**, the pre-update session still
+  interactive (typed input echoes, Ctrl+C interrupts), and **zero** unexpected
+  windows.
+
+## Safety
+
+This harness installs, overwrites, and can uninstall a real app. Two guards
+protect a developer's machine; a clean CI/VM is unaffected by either:
+
+- **Pre-existing app process → hard refusal.** If an Orca _app_ process (not a
+  daemon) is already running, the run aborts and prints the offending PIDs. The
+  harness never kills a process it did not start.
+- **Pre-existing install → refusal unless `--allow-existing-install`.** If an
+  Orca install already exists under `%LOCALAPPDATA%\Programs`, the run refuses,
+  because installing N then N+1 would silently overwrite that build and leave
+  the `--to` version behind. Pass `--allow-existing-install` to proceed anyway.
+
+Uninstall behavior at teardown follows ownership:
+
+- **No pre-existing install** (harness fully owns it): teardown silently
+  uninstalls, unless `--keep-install`.
+- **`--allow-existing-install` was used** (an install existed first): teardown
+  does **not** uninstall — removing a build the harness did not place would be
+  wrong. It prints a prominent note that the machine now has the `--to` version
+  and the prior build was not restored.
+
+## Isolated install mode (developer machines)
+
+On a clean CI/VM the harness installs into the default per-user location
+(`%LOCALAPPDATA%\Programs\Orca`). A developer's box already has a real Orca there,
+and the safety guards above would (correctly) refuse to run. **Isolated mode**
+(`--install-dir <path>`) lets the harness run on that box without disturbing the
+real install.
+
+**The /D mechanism.** electron-builder's NSIS honors the standard NSIS `/D=<path>`
+override for the install *directory* (`node_modules/app-builder-lib/templates/nsis/multiUser.nsh`).
+`/D` is special: it must be the **last** argument and **cannot be quoted**, so the
+path must be absolute and **spaces-free** (validated by `validateInstallDir`). The
+installer's kill-sweep only matches processes under its own `$INSTDIR`, so a
+separate directory never touches the real install's app or daemon processes.
+
+**Why registry/shortcut backup-restore exists.** `/D` relocates *files only*.
+Regardless of `/D`, the installer writes `InstallLocation` + the uninstall entry to
+the **same per-user HKCU keys** as the real install
+(`HKCU\Software\<APP_GUID>` and
+`HKCU\Software\Microsoft\Windows\CurrentVersion\Uninstall\<key>`,
+`node_modules/app-builder-lib/templates/nsis/include/installer.nsh`) and rewrites the
+Start Menu / Desktop shortcuts. Left hijacked, the user's **next real update would
+install into the test directory**. So isolated mode, before installing:
+
+1. **Snapshots** the shared state (`registry-shortcut-backup.mjs`): `reg export`s
+   each existing key to `.reg` files, copies the Orca `*.lnk` shortcuts, and records
+   a manifest (which keys/shortcuts existed, the pre-run `InstallLocation`).
+2. Runs the full install → update → assert proof against the isolated directory.
+3. **Always restores** at teardown (a `try/finally` wraps everything after the
+   snapshot): `reg import`s keys that pre-existed, `reg delete`s keys the test
+   created, copies shortcuts back / deletes test-created ones, then **re-reads
+   `InstallLocation` and verifies** it matches the snapshot. On mismatch it prints a
+   loud block with the exact manual `reg import` command to recover. Isolated
+   teardown **always** uninstalls the test install (the harness owns the directory)
+   and removes the directory if empty — `--keep-install` is ignored.
+
+**Residual risk.** The backup/restore covers `InstallLocation`, the uninstall entry,
+and the Orca shortcuts — the state that steers a future update and the user-visible
+launchers. It does **not** attempt to snapshot auto-update state files under the real
+install's `userData` (the harness uses an isolated `userData` throughout, so it never
+writes there), and it cannot restore state if the machine loses power mid-teardown
+(re-run with a valid `--install-dir` to let restore complete, or run the printed
+`reg import` by hand). The `.reg` backups live under the run's temp dir until a
+successful teardown removes it.
+
+**Example.**
+
+```
+pnpm win-update-e2e \
+  --from-release v1.4.124-rc.9 --to-release v1.4.125-rc.1 \
+  --expect cold-restore --install-dir C:\OrcaE2E
+```
+
+Read-only, touches nothing — print what isolated mode would snapshot on this machine:
+
+```
+node tools/win-update-e2e/registry-shortcut-backup.mjs
+```
+
+## What it does
+
+1. **Preflight** — assert win32; warn if elevated; **refuse** to run if a
+   pre-existing Orca _app_ process (not a daemon) is running that the harness
+   did not start (it is printed and the run aborts — the harness never kills a
+   user's processes); snapshot the baseline set of visible top-level windows.
+2. **Install N** silently (`<setup.exe> /S`) and locate `Orca.exe`.
+3. **Launch** the installed app (Playwright `_electron`, isolated userData),
+   create ≥2 terminals, start a **marker** in one: a `powershell` loop that sets
+   a unique window-title **canary**, records its PID, and heartbeats a file.
+4. **Record** the daemon PID (scoped pid-file + live-process scan), marker PID,
+   and session tab ids.
+5. **Close** the app normally; verify the detached daemon is still alive.
+6. **Start the window watch** — a background PowerShell loop polling visible
+   top-level windows every 500ms, diffing against baseline, recording every new
+   window (and title change) to a JSONL log through the update and soak.
+7. **Install N+1** silently (the update).
+8. **Relaunch** the app.
+9. **Assert** per profile, then print a PASS/FAIL/INFO evidence table.
+10. **Teardown** (unless `--keep-install`) — close app, kill only harness-created
+    processes, silent-uninstall.
+
+Exit code is `0` when every non-informational assertion passes, else `1`
+(`2` for a CLI usage error).
+
+## Standalone instrument self-tests (no installers needed)
+
+Each probe module runs on its own so the harness's own instruments are testable:
+
+```
+# Opens a real transient console window and asserts the watch catches it:
+node tools/win-update-e2e/window-watch.mjs --selftest
+
+# Read-only: list daemon processes + PID files on this machine:
+node tools/win-update-e2e/daemon-processes.mjs [--user-data <dir>] [--scope <substr>]
+
+# Emit the current visible-window snapshot as JSON:
+powershell -File tools/win-update-e2e/window-enum.ps1
+```

+## Known limitations
+
+- **Scrollback fidelity is best-effort.** A production build renders the
+  terminal with WebGL, so xterm text is not reliably in the DOM and the e2e
+  `SerializeAddon` is not exposed. When text cannot be read the check reports
+  `INFO` (unknown), never a false `FAIL`.
+- **Daemon file log** does not exist yet in packaged builds (the fork's stdio is
+  suppressed). The "daemon log free of ERROR lines" assertion is `INFO` until
+  Phase 0 daemon logging lands, then it reads `<userData>/logs/daemon.log`.
+- The harness assumes the packaged main honors `ORCA_E2E_USER_DATA_DIR` to
+  relocate userData; verify this against a real packaged build.

+  window-enum.ps1 — enumerate visible top-level windows with owner attribution.
+
+  Dot-source this file, then call Get-VisibleTopLevelWindows. It returns objects
+  { handle, pid, processName, title } for every visible, non-cloaked top-level
+  window that has a title.
+
+  WHY window enumeration (and never conhost command-line heuristics): the July
+  2026 post-mortem proved that (a) conhost flag interpretation inverts depending
+  on the parent's console state, and (b) MainWindowHandle is 0 for
+  Windows-Terminal-hosted consoles, so handle-based "is it visible" checks read
+  a visibly-flashing window as hidden. The only sound signal is a real visible
+  top-level window, attributed to an owner process and (for our own children) a
+  canary title. This function is the single instrument every probe shares.

+  window-watch.ps1 — poll visible top-level windows and record every NEW one.
+
+  Runs a tight loop (default 500ms) that diffs the current visible top-level
+  windows against a baseline snapshot, appending any window handle it has not
+  seen before to a JSONL file as one event per line:
+    { "ts": "<iso>", "handle": <n>, "pid": <n>, "processName": "...", "title": "..." }
+
+  It stops when -DurationSec elapses or -StopFile appears (whichever comes
+  first), so the orchestrator can end the watch deterministically after the
+  post-relaunch soak window.
+
+  Attribution is by owner process + title only (see window-enum.ps1 for why

+  "unexpected" (canary title, terminal/console owner) is done by the JS
+  assertions layer against this raw event log — this probe records everything.
