The file-vs-symbol heuristic only matched '/' — `codegraph node src\auth\session.ts` on Windows fell through to symbol mode and found nothing. Both separators now route to file mode, normalized to forward slashes (the form the index stores). Symbols never contain either separator in any indexed language. Validated: macOS smoke (explore/node symbol/node file/unindexed refusal) + Linux Docker (same smoke + full suite, 1428 passed). Windows VM validation queued — the Parallels guest is currently unreachable (control commands are Pro-gated; needs a manual start). Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
