Summary

Adds the unit-lane test that #3974's cache.ts change needed. That PR deleted the dist/apple/snapshot-bridge packaged fallback in resolveSnapshotBridgeSourceRoot; the maintainer merged it before this test landed, so the merged head failed the changed-line coverage gate (0/3) and main's single-root resolver has no unit coverage today. Test-only: one test asserting the two outcomes — the root-relative apple/snapshot-bridge directory resolves, and a project root without it reports native-source-missing. The setup writes exactly SNAPSHOT_BRIDGE_SOURCE_FILENAMES (the list the resolver checks) and one shared options object varies only projectRoot. 1 file.

Validation

Head 6511d57893 on a16d437237.

• pnpm check:affected --run --head 6511d57893: all runnable checks passed, exactCommit=true.
• cache.test.ts: 7 passed.
• Mutant (disposable git worktree at this head's tree, per test-audit): break the root check's path (apple/snapshot-bridge → apple) → this test fails (1 failed | 6 passed; baseline 7 passed).
• Test-only: no device lane, no nightly obligation.
• Self-review: no independent reviewer was available in this worker; the diff was re-read cold.

This PR is ready at 6511d57. The new source-root tests look correct, all 16 checks pass, and there are no conflicts. I did not run the tests or the mutant locally, and I did not trace findProjectRoot against an installed-package layout.

Not blocking, and you can take or leave these: the negative case at cache.test.ts#L176 uses an empty directory, so it would still pass if the removed dist/apple/snapshot-bridge fallback came back. A fixture that holds the sources only under path.join(root, 'dist', 'apple', 'snapshot-bridge') and expects native-source-missing would catch that. The same fixture shape could cover a bridge directory that lacks one SNAPSHOT_BRIDGE_SOURCE_FILENAMES entry. The test at L155 pins the single projectRoot/apple/snapshot-bridge path for both layouts, so you could name it after that one root.
