Merge Risk: 🟡 Moderate · up to Fix before merge: stale manager references can still delete index data after cleanup, and shutdown can leave recreated indexing services running. The identified lifecycle tests should also assert the missing behavior. Caution Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional.

✅ Passed checks (6 passed)
Full details: Regression EvidenceExplanation Focused coverage is incomplete for two changed manager lifecycle behaviors. Resolution Add manager-level tests. First, create a manager with mocked state/orchestrator/provider resources, call Full details: Lifecycle Resource CleanupExplanation The new disposal path does not cancel all in-flight initialization work. Resolution Make disposal cancellation cover the full asynchronous startup path. Add a disposed/cancellation check before and after every awaited initialization or indexing start, including

deactivate() to call CodeIndexManagerRegistry.disposeAll(). Ensure
registry-owned cleanup runs before the registry can serve managers on a later

- Around line 768-769: Remove the as any casts from the
CodeIndexManagerRegistry.getInstance calls by typing sharedContext as
vscode.ExtensionContext and passing it directly to both managerA and managerB.
In `@src/services/code-index/manager-registry.ts`:
- Around line 55-57: Update disposeAll() to snapshot and clear
managersByWorkspacePath before disposing entries, then attempt
instance.dispose() for every snapshot manager while retaining the first thrown
error. After all disposal attempts complete, rethrow that first error so later
managers are always processed and the registry remains cleared.

All 14 extension tests and monorepo lint/type checks pass locally. The diagnostic assertion finding was already fixed in 8ae217c and its thread is now resolved. Waiting for CI and automated review of the latest commit. |

Final validation update for b583717: all test/build/security checks, Linux and Windows coverage jobs, Codecov patch checks, and mutation-diff are passing. All known review findings have been addressed. The repository review gate still reports "Required CI passed. Waiting for automated review of the latest commit." Maintainer review/review-process follow-up is needed; no review-state labels or gate settings have been changed. |

Addressed the lifecycle cleanup finding in 3657535 with a deliberately minimal guard. CodeIndexManager.dispose() now marks the instance disposed and is idempotent. If disposal occurs while service recreation is in flight, initialize() stops the late-created orchestrator/provider, clears the initialized service references, and does not start indexing. Added a focused regression test for this race. The registry disposal-failure recovery case is covered as well. Focused tests (42), lint, and type checks pass. |

Cover the pending Semble-provider disposal path.
This test only creates _orchestrator and _searchService after recreation. It does not execute this._sembleProvider?.dispose() in initialize(). Add a parallel test that creates a fake Semble provider after the pending recreation completes, then assert stopIndexing() and dispose() each run once after disposal.
As per path instructions, tests must cover relevant lifecycle paths with behavior-focused assertions.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert the resolved initialize() value after disposal.
The disposal branch returns { requiresRestart }, and this test configures requiresRestart as false. The current await initialization assertion does not detect an incorrect {} result. Use await expect(initialization).resolves.toEqual({ requiresRestart: false }).

Guard handleSettingsChange() after service recreation.
handleSettingsChange() can await _recreateServices() while extension shutdown calls dispose(). For non-Semble providers, _recreateServices() assigns _orchestrator and _searchService after awaited setup. Without a post-await _disposed check, the manager can retain these services after disposal and report itself initialized, while later dispose() returns early. Apply the same cleanup guard used by initialize() after this await.

Add direct coverage for CodeIndexManager.dispose() idempotency.
No manager-level test calls dispose() twice on the same manager. Registry cleanup does not cover this branch because it clears the registry before the second cleanup. The Line 301 conditional mutant survives for this reason. Stub a Semble provider, call manager.dispose() twice, and assert its dispose() method runs once.
As per path instructions, tests must cover relevant lifecycle paths with behavior-focused assertions.

Reject clearIndexData() after disposal.
dispose() sets _disposed but retains _configManager, _orchestrator, and _cacheManager. For an initialized manager, clearIndexData() still passes isFeatureEnabled and can delete the vector collection and cache through those services. Add an early _disposed guard to prevent retained managers from mutating index state after registry cleanup.

Related GitHub Issue
Closes #1594
Related umbrella tracker: #1592 (not closed by this PR).
Description
Indexing, scanner, provider and orchestrator behavior is not redesigned here. One deliberate implementation detail: vscode.Uri.file replaces the hand-built fallback URI for explicit paths outside open workspace folders. Its canonical serialization can change URI-derived keys for unusual paths; real workspace folder URIs are preserved.
Test Procedure
Local validation on macOS (Node 24.7.0; repository requests Node 22.23.1, so CI remains authoritative):
Registry tests: run
pnpm exec vitest run services/code-index/__tests__/manager-registry.spec.ts services/code-index/__tests__/manager.spec.tsfromsrc.Full CI/Codecov results are pending; no manual extension-host smoke test was performed.
