Conversation (30 messages)

Perform a fresh read-only security audit of only the filesystem/archive half of issue #4 frozen-input verification in /home/byk/Code/institutional-transition-lab. This replaces a reviewer that returned empty twice and is disjoint from the JSON/pin/snapshot reviewer. Never edit files and never inspect governance record bodies, coding decisions, outcomes, reports, dates, detector output, or source-adjudication scopes.

Scope only:

  • regular-file descriptor opening and rejection of symlinks, FIFOs, devices, and other special files without blocking
  • input byte limits and read behavior
  • ZIP entry count and total/per-member resource limits
  • duplicate required members, normalized/path/case/backslash collisions, absolute/parent paths, symlink/encryption metadata
  • decompression and exact required-member byte comparisons
  • narrowly corresponding tests/probes

Do not review strict JSON parsing, frozen pin identity/order, canonical hash semantics, or CLI output writing; other reviewers own those. Primary files are src/institution_lab/governance_adjudication.py and only relevant tests in tests/test_governance_adjudication.py. Review current working copy read-only.

Return substantive evidence, never empty. Findings first, severity ordered, with exact current file:line references and PASS/CONCERN/MUST-FIX/BLOCKED labels. Every defect needs a deterministic regression. If no defects, state PASS and identify tests/probes plus residual risks. End exactly MERGE or DO-NOT-MERGE.

Your prior result was empty. Complete the same read-only filesystem/archive security audit now and return substantive evidence or an explicit blocker. Never edit files. Scope remains only: regular-file descriptor opening and rejection of symlinks/FIFOs/devices/special files without blocking; input byte limits/read behavior; ZIP entry count and total/per-member resource limits; duplicate members and normalized/path/case/backslash collisions; absolute/parent paths, symlink/encryption metadata; decompression and exact required-member byte comparisons; and narrowly corresponding tests/probes in src/institution_lab/governance_adjudication.py and tests/test_governance_adjudication.py. Do not review JSON parsing, frozen pin identity/order, canonical hash semantics, CLI output writing, governance bodies/codings/outcomes/reports/dates, or source-adjudication scopes. Review the unchanged current working copy. Findings first with exact current file:line evidence and PASS/CONCERN/MUST-FIX/BLOCKED labels; include a deterministic regression for each defect and commands/probes run. Never return empty. End exactly MERGE or DO-NOT-MERGE.
