Perform a fresh, smaller, read-only security audit of only required-member stream integrity for issue #4 in /home/byk/Code/institutional-transition-lab. This replaces a ZIP-stream reviewer that returned empty twice and is disjoint from the resource-accounting audit. Never edit files or inspect governance bodies, codings, outcomes, reports, dates, detector output, or source-adjudication scopes.

Scope only: unique selection and opening of required documents.json and v1.2-adjudication-package.json; CRC/corrupt/truncated stream handling; exact member bytes compared with the already verified durable payload bytes; member read cleanup/error behavior; whether malformed required streams can be accepted or parsed. Do not review archive path/name/mode/encryption/count metadata except uniqueness needed for these exact names; decompression resource accounting; _read_regular_file; JSON strictness; pin identity/hash ordering; or CLI outputs.

Primary files: only relevant required-member ZIP code in src/institution_lab/governance_adjudication.py and narrow tests in tests/test_governance_adjudication.py. Run read-only tests/probes. Return substantive evidence, never empty. Findings first, severity ordered, exact current file:line references, PASS/CONCERN/MUST-FIX/BLOCKED labels; deterministic regression for each defect. If clean, state PASS with probes and residual risks. End exactly MERGE or DO-NOT-MERGE.

I’ll inspect only the required-member extraction path and its narrow tests, then run isolated read-only probes for duplicate selection, CRC corruption, truncation, cleanup, byte equality, and parse reachability.

Your first result was empty. Complete the same narrow read-only required-member stream-integrity audit now and return substantive evidence or an explicit blocker. Never edit files. Scope only in /home/byk/Code/institutional-transition-lab: unique selection/opening of required documents.json and v1.2-adjudication-package.json; CRC/corrupt/truncated stream handling; exact member bytes compared with already verified durable payload bytes; member-read cleanup/error behavior; whether malformed required streams can be accepted or parsed; narrowly corresponding code/tests in src/institution_lab/governance_adjudication.py and tests/test_governance_adjudication.py. Do not review general archive path/name/mode/encryption/count metadata beyond exact required-name uniqueness, decompression resource accounting, regular-file reads, JSON strictness, pin identity/hash ordering, CLI output, or governance/source scopes. Review unchanged current working copy and run narrow read-only probes. Findings first with exact file:line evidence and PASS/CONCERN/MUST-FIX/BLOCKED labels; deterministic regression for each defect. Never return empty. End exactly MERGE or DO-NOT-MERGE.

Findings

MUST-FIX — Truncated compressed streams are accepted and parsed

archive.open(info).read(...) trusts ZipExtFile to validate the compressed stream (governance_adjudication.py:201-202). The only later integrity check compares returned decompressed bytes with durable bytes (governance_adjudication.py:203-206). It never checks whether the compression stream reached its native end marker. Parsing then proceeds at governance_adjudication.py:209 and :215.

Deterministic in-memory probes removed the final compressed byte while preserving the complete decompressed payload and CRC:

  • ZIP_DEFLATED: accepted for both required members; native decompressor eof=False.
  • ZIP_BZIP2: accepted for both; eof=False.
  • ZIP_LZMA: accepted for both; eof=False.
  • In every case, the verifier accepted the bundle and invoked all downstream parsers.

Thus malformed required streams can be accepted and parsed.

Required regression: Parameterize both required names and all three compression methods. Remove the terminal compressed byte while preserving the expected uncompressed bytes and CRC. Assert ValueError before _parse_json_object runs.

CONCERN — Corrupt DEFLATE errors escape without normalization

The read at governance_adjudication.py:202 can raise native decompressor exceptions, but governance_adjudication.py:207-208 catches only zipfile.BadZipFile.

Setting DEFLATE’s block type to the reserved value produced zlib.error: invalid block type for either required member. Neither case reached parsing. Source and archive context managers still closed correctly.

Required regression: Corrupt each required member with the reserved DEFLATE block type. Assert a validation ValueError with the decompressor error retained as its cause, no parser invocation, and closed source/archive handles.

Passing checks

  • PASS — Required-name selection: Exact duplicates and missing entries are rejected by ...
