Conversation
The fuzzy fallback dropped the path constraint whenever `path` ended in an extension, without checking that the pinned file was reachable. Any path under an excluded directory (node_modules/**) therefore turned into a repo-wide fuzzy search presented as if it concerned the pinned file. Widening is now limited to paths that resolve to nothing on disk (a misnamed guess) and says so; an existing-but-unindexed target reports that instead. Closes #830
📝 WalkthroughWalkthroughThe fuzzy grep fallback now checks whether a pinned path exists and whether it is indexed. Existing files keep the path constraint. Missing files trigger an explicit repo-wide fallback notice. Tests cover all path cases. ChangesFuzzy grep path handling
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to Existing extensionless files that are excluded from indexing can still return only a generic no-match result instead of the intended unindexed-file notice. This is a bounded user-visible correctness gap requiring owner awareness or follow-up, but it does not broaden results or create a security or availability risk. Sequence Diagram(s)sequenceDiagram

Check existing extensionless files too.
Line 936 calls resolvePinnedFile only for names that match the extension heuristic. An excluded existing file such as LICENSE or Dockerfile keeps its constraint, but it cannot reach the isIndexedFile branch. The result is only No matches found, not the required unindexed-file notice.
Proposed fix
- const pinnedFile =
- pathTargetsFile && params.path
- ? resolvePinnedFile(params.path, activeCwd)
- : null;
+ const pinnedFile = params.path
+ ? resolvePinnedFile(params.path, activeCwd)
+ : null;Add a regression test for an existing unindexed extensionless file.

Closes #830
Root cause
packages/pi-fff/src/index.ts:930-932decided to drop thepathconstraint from the fuzzy fallback purely from the trailing extension ofparams.path, never checking that the pinned file was reachable in the picker. SinceroutePathConstraint(packages/pi-fff/src/aux-finders.ts:165) keeps workspace-relative paths on the workspace finder, and that index excludesnode_modules/**, every grep pinned there returned 0 exact matches and then re-ran repo-wide with the constraint gone.Fix
Widening is now limited to the case the heuristic was written for: a
paththat resolves to nothing on disk (misnamed guess), and the notice says the constraint was dropped. A pinned file that exists keeps its constraint; if it is also absent from the index, the notice states that instead of returning unrelated files.Steps to reproduce
Then, with the checked-out extension loaded (
pi -e packages/pi-fff/src/index.ts -p --no-session ...), call:expected — the pinned path is honoured:
actual on
main— constraint silently dropped, unrelated file returned:The same three cases are covered deterministically by the new tests in
packages/pi-fff/test/extension.test.ts(pi-fff grep fuzzy fallback); they fail onmainwith exactly the output above and pass here.How verified
Against the real native picker on the fixture above (temporary harness, not committed):
glob("package.json")returnspackage.json,glob("node_modules/react/package.json")returns[], andffgrepwith the pinned path yields thenot indexedmessage forjsx-runtimeandsideEffectsinstead ofsrc/renderer/App.tsx.bunx oxfmtandbunx oxlint packages/pi-fffclean. The extraglobpass runs only after an exact grep already returned zero rows, so no hot query gains work.@dmtrKovalenko one unrelated thing surfaced while verifying: with
path: "node_modules/react/package.json"andpattern: "version", the exact grep still matched the workspace-rootpackage.json. That isnormalizePathConstraintemitting a FilePath constraint that matches on basename, not the fallback, and it lives in the query parser — left alone here.Automated triage via Gustav. Honk-Honk 🪿
