📄 Description

Summary

Refuse UNC pathnames in file:// URIs as network shares before calling Node's fileURLToPath.

Problem and expected behavior

When a file:// URI contains leading slashes representing a UNC path (such as file:////remote.example.test/share/state.json), Node's fileURLToPath on Windows throws ERR_INVALID_FILE_URL_PATH because Windows paths expect a drive letter or standard absolute path. The exception handler caught this and returned "invalid params: a file:// uri names a local absolute path" instead of the intended "invalid params: a file:// uri names a path on this host, not a network share", causing src/server/environment/serveEnvironmentState.test.ts to fail on Windows.

Change and scope

Check UNC_PATH.test(url.pathname) before calling fileURLToPath in localFilePath (src/server/environment/stateIntake.ts). This ensures UNC paths with leading slashes (//... or \\...) are consistently recognized and refused as network shares across all platforms.

Contract and boundary impact

  • Semantic owner and earliest changed stage: src/server/environment/stateIntake.ts
  • Contribution scope fit and linked maintainer decision: not applicable (existing input validation bug fix)
  • CLI and MCP/tool-catalog contract: none
  • Provider, bridge, target-format, or platform compatibility: Windows and POSIX parity
  • Evidence, artifact, provenance, or reconstruction contract: none
  • Target selection, authority, upstream behavior, and cleanup details (if applicable): none
  • Generated metadata (docs/public/product-catalog.json), package, or installation impact: none

Expected effects:

  • Documentation or usability only; no target interaction.

Evidence and regression coverage

  • Tests added or updated: src/server/environment/serveEnvironmentState.test.ts (existing test opens file uris only on this host, refusing another host or a network share before opening anything now passes on Windows)
  • Base reproduction or other evidence: On Windows without this fix, fileURLToPath(new URL("file:////remote.example.test/share/state.json")) threw ERR_INVALID_FILE_URL_PATH, triggering the local absolute path error instead of the network share error.
  • User-visible CLI/MCP output (if applicable): not applicable
  • Remaining proof gaps: none

For evidence-bearing changes:

  • Observed, derived, and inferred claims remain distinguishable.
  • Artifact identity, source provenance, and failed attempts remain preserved.
  • Unsupported, incomplete, unavailable, or uncertain outcomes remain visible.

Validation performed

  • npm.cmd run test:local -- src/server/environment/serveEnvironmentState.test.ts ? 23 passed (23)
  • npm.cmd run check:fast ? 2 successful, 0 errors (typecheck + lint)
  • npm.cmd run format:check ? all matched files use correct format (oxfmt)
  • npm.cmd run verify:architecture-guards ? passed across 1760 source files
  • npm.cmd run verify:module-boundaries ? passed across 2543 source files

Compatibility, safety, and release

  • Breaking changes or migration steps: none
  • Real Hopper/Ghidra, browser, or OS coverage: Windows x64 tested
  • Package or release metadata impact: none
  • Security, privacy, process, or containment review: preserves and enforces network share boundary
