📄 Description

Summary

Fixes #3988

Keep relationship coverage unknown when a modern headless IDA callees page omits its more truncation marker, so trace_call_path no longer turns unproven callee coverage into goal_status: "not_reached". Observed callee rows are still returned. An explicit more: false stays complete and more: true stays partial.

Problem and expected behavior

In IdaOperationRunner, the modern callees branch mapped every page that was not explicitly capped (more !== true) to { status: "complete" }. A page without more therefore claimed complete coverage. CallPathTracing adds a residual unknown only for partial or unknown coverage, so a trace to a goal outside the listed callees ended as not_reached with no residual unknowns.

Pinned upstream callees (mrexodia/ida-pro-mcp c133c385, api_analysis.py) always emits more on success, so its absence means the reply does not report coverage. The native schema already rejects that omission (IdaNativeProtocol.ts), and the legacy branch already reports unknown coverage when the reply does not report it.

Expected behavior: an omitted marker yields unknown coverage with a reason, the observed rows remain, and a trace to an unlisted goal stays unknown.

Change and scope

  • src/ida/IdaOperationRunner.ts: more: false maps to complete, more: true to partial as before, and an omitted more to unknown with the reason "Upstream callees omitted an explicit truncation marker; additional callees remain unknown."
  • Not included: the native protocol, which already rejects the omission at its schema, and the callgraph path for non-x86 targets.

Contract and boundary impact

  • Semantic owner and earliest changed stage: modern IDA callee coverage in IdaOperationRunner.
  • Contribution scope fit and linked maintainer decision: not applicable (bug fix within the existing IDA provider).
  • CLI and MCP/tool-catalog contract: unchanged schemas; relationshipCoverage can now be unknown for this reply shape.
  • Provider, bridge, target-format, or platform compatibility: modern headless IDA on x86 targets. Native and legacy profiles are unchanged.
  • Evidence, artifact, provenance, or reconstruction contract: unproven coverage is no longer reported as complete.
  • Target selection, authority, upstream behavior, and cleanup details (if applicable): not applicable.
  • Generated metadata (docs/public/product-catalog.json), 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:
    • src/ida/IdaCalleeRelationships.test.ts: an x86 callees page without more returns the observed 0x2000 row with unknown coverage and the new reason.
    • tests/boundary/providers/ida/calleeRelationships.test.ts: trace_call_path from main to an unlisted resolved goal returns goal_status: "unknown" with a residual unknown for 0x1000.
  • Base reproduction or other evidence: source-derived. On the base revision the same page yields { status: "complete" }, so projectTrace reaches not_reached because state.residual stays empty. Existing modern fixtures all send more: false and keep complete coverage.
  • User-visible CLI/MCP output (if applicable): trace_call_path reports goal_status: "unknown" and a residual unknown instead of not_reached.
  • Remaining proof gaps: no real IDA engine was run; tests use the simulated producer.

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

  • No local test commands were run: verification is source-derived; CI executes the deterministic suite.

Compatibility, safety, and release

  • Breaking changes or migration steps: none.
  • Real Hopper/Ghidra, browser, or OS coverage: none run. No IDA process is launched by these tests.
  • Package or release metadata impact: none.
  • Security, privacy, process, or containment review: no change to process ownership or target handling.
