ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR substantially changes every existing workspace-search path by introducing a shared native child process, IPC protocol, timeout/recovery lifecycle, and new packaging behavior. It also adds static-analysis suppressions and has an unresolved Medium finding about incorrect truncation reporting for image-only searches.

- Line 58: Update WorkspaceSearchHost.request and its onError(stop) handling to
retire the worker for active-request interruption, initialization failures,
WorkspaceSearchIndexCreateFailed, WorkspaceSearchIndexScanTimedOut,
WorkspaceSearchProcessFailed, TimeoutError, and defects, while preserving the
worker for WorkspaceSearchIndexSearchFailed and
WorkspaceSearchIndexRefreshFailed. Ensure interruption while waiting for the
semaphore does not invoke stop, and retain worker termination to cancel native
work and release the manually created scope.
In `@apps/server/src/workspaceSearchWorker.ts`:
- Line 1: Register the workspace search worker entry represented by
workspaceSearchWorker.ts in the repository’s Knip configuration, or update the
existing Vite entry configuration so Knip discovers it. Keep the worker as a
recognized bundled entry and avoid unrelated dependency or build changes.

Set The CI checks and the added unrelated-idle-index cleanup test pass. The failure exists in the active-index cleanup path that the current test does not cover. 🧠 Learnings used

The remaining generic docstring-coverage warning does not warrant boilerplate here: AGENTS.md asks us to keep implementation explanations in nearby comments and rely on types and tests for discoverable behavior. The worker lifecycle and transport constraints have local comments and focused tests. Latest-commit CodeRabbit and Macroscope correctness checks are passing; Macroscope approvability remains neutral pending maintainer review of the process boundary. |

- Around line 102-103: Move the 20-second Effect.timeout from outside
semaphore.withPermits into the permit-protected operation in Effect.fn, before
Effect.onError, so the deadline measures active work only and a timeout while
queued cannot call stop() and retire the worker. Add a regression test in
WorkspaceSearchIndex tests that delays initialize after restart beyond the
queued request’s remaining deadline and verifies the rebuilt worker remains
alive.

Note This comment is posted by Julius' dot The current diff combines worker isolation for #11306 with separate search-correctness fixes: retrying dense whole-word result pages and preserving literal backslashes in POSIX filenames. Both defects exist in the base implementation and can be fixed independently of the IPC boundary. Under one underlying problem per PR, please split those fixes from process isolation and link the focused replacements. The isolation tests and native/build verification remain useful for reconsideration. |

Native workspace search can block the server event loop, preventing request deadlines, cancellation, and unrelated HTTP or provider traffic from making progress.
Move native indexes into one scoped IPC child process. Serialize searches, give each active request a fresh 20-second deadline, bound disposal, and rebuild indexes after a crash, timeout, or active cancellation while preserving the worker after ordinary search errors. npm installs launch a sibling worker; standalone executables use a hidden subcommand and load the native index only in that child.
Validation: 57 focused native, worker-lifecycle, and workspace-entry tests passed, plus server type checking and scoped lint. Both npm and Linux standalone builds passed. The source worker was exercised with Node 22.16 through the Effect host as well. Real native initialize, list, and search succeeded through source, npm, and standalone worker entry points.
Whole-word searches retry full raw pages before advancing the file cursor, so rejected candidates cannot hide later valid matches. Retries retain the search deadline and a candidate bound and report incomplete results when either is reached. POSIX search results preserve literal backslashes in filenames. Image-only searches retain the incomplete-scan signal and report truncation when selected images exceed the result limit.
Fixes #11306.
