📄 Description

Summary

Fixes #3183. When REA_CUTTER_BRIDGE_DIR was set to ~/... or to an empty string, CutterBridgeClient used it as given (configured ?? default), so it looked in a literal ~ folder or the current directory and live Cutter sessions disappeared. The Python bridge (bridge/cutter/rea_bridge.py) already expands ~ and treats an empty value as unset, so the two sides disagreed about where the bridge directory was.

Problem and expected behavior

Smallest trigger: REA_CUTTER_BRIDGE_DIR='~/rea-bridge' (quoted, so the shell doesn't expand it) or REA_CUTTER_BRIDGE_DIR=''. The Cutter plugin writes sessions under the expanded or default directory, but the TS client reads from ~/rea-bridge relative to the working directory, or from '', and reports no sessions. Expected behavior: the client resolves the same directory as the Python bridge.

Change and scope

In src/cutter/CutterBridgeClient.ts, the configured value is resolved like this:

  • A leading ~ or ~/... expands to the home directory.
  • An empty or whitespace-only value is treated as unset, so the platform default is used.
  • Any other path is unchanged.

Not included: other environment variables, ~user expansion, and any change to the Python bridge.

Contribution scope: an ordinary fix within existing boundaries, so no maintainer scope decision is needed.

Contract and boundary impact

  • Semantic owner and earliest changed stage: src/cutter/CutterBridgeClient.ts, when it resolves the bridge directory.
  • Contribution scope fit and linked maintainer decision: ordinary bug fix; not applicable.
  • CLI and MCP/tool-catalog contract: none.
  • Provider, bridge, target-format, or platform compatibility: the TS client now matches the Python Cutter bridge's resolution. Paths that were already valid are unchanged.
  • Evidence, artifact, provenance, or reconstruction contract: none.
  • Target selection, authority, upstream behavior, and cleanup details (if applicable): not applicable.
  • Generated metadata, package, or installation impact: none.

Expected effects:

  • Read existing files or captured data.
  • Launch or attach to a process.
  • Inject instrumentation or run scripts/code.
  • Change process memory, registers, files, or configuration.
  • Contact network services.
  • Recover protected code or work around protections.
  • Documentation or usability only; no target interaction.
  • Not sure yet; investigation or maintainer guidance needed.

Evidence and regression coverage

  • Tests added or updated: CutterBridgeClient tests for ~, ~/x, "", whitespace-only, and a normal absolute path.
  • Base reproduction or other evidence: executed. On the old resolver, the ~ case returned ~, ~/x returned ~/x, "" returned an empty string, and whitespace was kept, so all four failed. The normal path /var/tmp/rea-cutter-bridge already passed. With the fix, all five pass.
  • User-visible CLI/MCP output (if applicable): not applicable. Only directory resolution changes.
  • Remaining proof gaps: no live Cutter session was run end to end, and macOS/Windows home-directory resolution wasn't run locally.

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 run check:fast — passed (typecheck and lint).
  • Focused Cutter tests (CutterBridgeClient, CutterBridgeCapacity, CutterBridgeNullIdentity, cutterBridgeProducer, cutterCommands, cutterMcp) — passed, 47 tests.

Compatibility, safety, and release

  • Breaking changes or migration steps: none. Setups that used ~ or an empty value were already broken. Explicit paths behave the same.
  • Real Hopper/Ghidra, browser, or OS coverage: Linux only, and no live Cutter run.
  • Package or release metadata impact: none.
  • Security, privacy, process, or containment review: none. No new process, network, or file authority.
