Slashed file chips such as docs/GROUPS_PLAN.md opened a nonexistent path when the file lived in a nested directory. Fixes #8251.
Chips now check the literal path first, so any existing file or directory opens as written without waiting for the index. Only a missing path searches the workspace index, resolving to the one file that ends with it; ambiguous matches keep the authored path. Panel, editor, reveal, and browser actions share main's newest-click claim, so a slow lookup can't override a newer action.
This re-ports @juliusmarminge's takeover onto current main, which has since moved the lookup into @t3tools/client-runtime and landed #18389. The original commits stay in the branch history.
vp run check:changed passes against current main.Captured on the earlier head f3338cb, which resolves these cases the same way; not re-captured after the re-port.

Workspace file links now use normalized paths and indexed matches. A literal-path check can take precedence when a different indexed path matches. Panel, editor, and browser opens use resolved paths when available, with lookup claims scoped by thread.
Changes: Workspace file links
| Layer / File(s) | Summary |
|---|---|
Normalize and match lookup paths apps/web/src/workspaceBasenameLookup.ts, apps/web/src/workspaceBasenameLookup.test.ts | Lookup paths are normalized. Matching prefers exact paths and segment-boundary suffixes. Tests cover ambiguous matches, invalid paths, literal-file checks, and claims scoped by thread. |
Resolve indexed matches against workspace files apps/web/src/components/ChatMarkdown.tsx | Workspace lookup uses normalized paths. A literal-path read can suppress a differing index match when the literal file exists. Panel lookup claims are scoped by thread. |
Use resolved paths for file-opening actions apps/web/src/components/ChatMarkdown.tsx | Editor and browser actions use resolved paths when available. Editor actions preserve line and column positions. Superseded lookups stop. |

Guard editor and browser lookups against stale clicks.
claimWorkspaceBasenameLookup defines newest-click-wins behavior within a thread, and openFileInPanel already enforces it. The editor and browser callbacks await findWorkspaceBasenameMatch without claiming or checking a lookup. If an earlier lookup settles after a newer click, it can open the wrong target last.
Claim the scoped lookup before the await and check it before either fallback or open operation. Preserve the existing fallback paths.

Preserve literal files when a read fails after existence is established.
operation_failed is too broad to add as an unconditional existence signal. However, readFile can return it after opening and confirming that the path is a regular file. literalWorkspaceFileExists then returns false, so findWorkspaceBasenameMatch can select a different indexed match.
Use filesystemGetMetadata for this existence check, or classify only operation_failed results whose operation occurs after the successful regular-file check. Do not treat open, realpath-*, or stat failures as proof that the path exists.

Confirmed at e6e967fb7d6bfa49617d3a9290c31437ff17811a: capped search results can make an ambiguous slashed file link open an arbitrary candidate.
Reproduced on synthetic files using the PR-pinned native @ff-labs/fff-node@0.11.0, the server's path-index options, and unchanged server mapper / PR lookup and panel functions:
a/src/foo.py, z/src/foo.py, and 24 files f0/src/foo.py.bak through f23/src/foo.py.bak. Leave literal src/foo.py absent.src/foo.py with client limit 25 and native pageSize: 26, as the server does.z/src/foo.py at position 26. mapFileSearchResult slices to 25 and returns truncated: true, leaving only a/src/foo.py as a visible suffix match.findWorkspaceFileMatch ignores truncated, so openFileInPanel receives a/src/foo.py. Giving the chooser the full native results rejects the ambiguity instead.The same issue reproduces with 25 .bak files, where the second suffix falls outside the native page itself. Controls confirm that complete ambiguous results retain the authored path and an existing literal file wins. The original a/ + b/ fixture did not reproduce with native ranking; the a/ + z/ fixture above did, including a repeat run.
Suggestion: do not treat results with truncated: true as proof of uniqueness for the suffix fallback; preserve the authored target unless uniqueness can be established. Please cover this capped-result case with a regression test. The existing action test currently expects a redirect with truncated: true.
Verification scope: actual native index plus unchanged extracted mapping/lookup/panel functions, with the RPC contract and success-response mapping inspected. No full T3 server, WebSocket integration, or React UI was run. Incomplete initial scanning was not reproduced; this finding concerns the confirmed result-cap case only.
