macOS code signing rewrites unpacked native modules after electron-builder
records their ASAR integrity, so the declared and observed hashes of
those .node files differ in most signed Electron apps. Claude, ChatGPT,
Notion, Obsidian, and Tabby all failed inspect_artifact,
extract_artifact, and analyze_javascript_application by default. Only
inspect_artifact offered integrity_policy, so extraction and JavaScript
analysis of these apps was impossible.
extract_artifact and analyze_javascript_application now accept the same
integrity_policy (default fail). With record-and-continue, extraction
writes the observed bytes, and JavaScript analysis reads contradicted
files as observed. Contradicted nested archives stay unexpanded. Both
results return the recorded integrity_contradictions and a limitation.
The mismatch remediation now names this option instead of only advising a
fresh copy, which cannot help for a signed installation.
