📄 Description

Summary

Fixes #3990

Reject a modern headless IDA find_regex page that carries an embedded producer error, including a completed empty match list with a terminal cursor. search_strings must not present that page as a successful scan that found no strings.

Problem and expected behavior

The headless IDA adapter returns a successful empty search_strings result when a modern string page contains an explicit producer error, an empty match list, and a terminal cursor. The caller receives the failure only inside raw Evidence. A failed scan can look like a complete search that found no matching defined strings.

nativeStringsSchema already throws on page.error. modernStringsSchema omitted the field, so Zod stripped error and the runner mapped matches: [] as success.

Expected behavior: the same embedded error is an AnalysisProtocolError. A later empty page without error remains a successful empty result.

Change and scope

• In src/ida/IdaProtocolValues.ts, admit optional error on modernStringsSchema.
• In src/ida/IdaOperationRunner.ts, raise AnalysisProtocolError when the parsed page includes error.
• In src/ida/IdaSessionClient.test.ts, drive headless search_strings for the failing page and a clean empty page.

Contract and boundary impact

• Semantic owner and earliest changed stage: IDA string inventory in src/ida/IdaOperationRunner.ts and modernStringsSchema.
• Contribution scope fit and linked maintainer decision: not applicable (bug fix within existing IDA string search).
• CLI and MCP/tool-catalog contract: unchanged schemas. Failed search is a protocol error instead of a successful empty list.
• Provider, bridge, target-format, or platform compatibility: modern headless IDA MCP find_regex. Native pages still fail in nativeStringsSchema.
• Evidence, artifact, provenance, or reconstruction contract: producer errors are no longer presented as complete empty inventories.
• 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/IdaSessionClient.test.ts: headless search_strings fails with AnalysisProtocolError when find_regex returns error: "Search fixture failed" on an empty completed page, then succeeds with [] when a later page has no error.
• Base reproduction or other evidence: on the base revision, modern error is stripped and search_strings returns a successful empty list.
• User-visible CLI/MCP output (if applicable): search_strings reports a protocol failure naming the producer error.
• Remaining proof gaps: tests were verified by source inspection; CI executes the deterministic suite. No IDA engine was launched.

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. A previously successful empty result for an embedded producer error becomes a protocol failure.
• Real Hopper/Ghidra, browser, or OS coverage: none run.
• Package or release metadata impact: none.
• Security, privacy, process, or containment review: no added execution authority; failed producer pages are no longer treated as complete absence.

Before merge

• This PR addresses a concrete problem or an agreed enhancement.
• Material scope and authority questions are resolved, and any required maintainer scope decision covers the final diff.
• The PR has one focused outcome and the title follows type(scope): outcome.
• Related issue is linked, or the reason for not linking one is stated above.
• Tests cover changed observable behavior and meaningful failure paths.
• Owning docs, contracts, and generated metadata are updated where needed.
• User-visible CLI/MCP changes include representative output.
• I checked the final diff for secrets, unrelated cleanup, and unsupported claims.
