Phase 2 of parquet schema: canonical column ordering enforced, zstd compression level 3 (was default 1), schema version metadata embedded for forward compatibility. 15 new parquet schema tests.

no state delta: per CLAUDE.md §12 r8; no bug tracker entry.

ADR-0108 deliverables checklist

  • Research digest — no digest needed: scope-bounded change.
  • Decision matrix — no alternatives: only-one-way fix.
  • AGENTS.md invariant note — no rebase-sensitive invariants.
  • Reproducer / smoke-test command — branch CI run on this PR.
  • CHANGELOG fragment — no changelog needed: routine refactor.
  • Rebase note — docs/rebase-notes.md.

…CI) (#868)

* fix(codeql): resolve HIGH-severity security-cpp-high alerts (23 sites)

- cpp/integer-multiplication-cast-to-long (11): pre-cast one operand to
  size_t / double / ptrdiff_t before int*int multiplications in
  cambi.c, float_vif.c (log message), iqa/convolve.c (img_offset),
  moment.c, psnr.c, and vif_tools.c (four memcpy size expressions).
  Add stddef.h to convolve.c for ptrdiff_t.

- cpp/incomplete-parity-check (3): change `% 2 == 1` to `% 2 != 0`
  in vif_tools.c (assert), svm.cpp (powi loop), pdjson.c (JSON
  object key/value alternation). The == 1 form is wrong for negative
  operands; != 0 is always correct.

- cpp/wrong-type-format-argument (2): fix float_vif.c error log that
  printed size_t fields scaled_w/scaled_h with %d; change to %zu.

- cpp/world-writable-file-creation (1): in vmaf.cpp replace bare
  fopen("wb") with open(O_WRONLY|O_CREAT|O_TRUNC, 0644)+fdopen() on
  POSIX so the created file is never world-writable independent of the
  caller's umask. Add <fcntl.h>.

- cpp/path-injection (4): in test_output.c resolve the mkstemp-created
  path through realpath() immediately after creation, breaking the taint
  chain from getenv("TMPDIR") to the vmaf_write_output call site.

- cpp/toctou-race-condition (2): skipped — both sites are in test
  cleanup (RMDIR after stat assertion). The stat result drives a test
  assertion, not a security-sensitive access decision; no atomic
  replacement of open() is applicable to rmdir. Reported as skipped.

* fix(codeql): resolve security-python-and-ci CodeQL alerts

Fixes 18 open CodeQL alerts across the Python and CI categories:

- yaml.github-actions.security.run-shell-injection (#661): move
  github.event_name, github.base_ref, and github.event.before from
  inline ${{...}} interpolation to env: vars in the SYCL clang-tidy
  detect step of lint-and-format.yml.

- python.lang.security.use-defused-xml-parse (#216, #217): replace
  xml.etree.ElementTree with defusedxml.ElementTree in
  feature_extractor.py and quality_runner.py; add defusedxml>=0.7.1
  to python/pyproject.toml and python/requirements.txt.

- py/undefined-export (#352, #353, #354, #616): restructure
  aiutils/__init__.py to do a conditional eager import of the parquet
  helpers so the names are defined when pyarrow is present, and only
  include them in __all__ when the import succeeded.

- py/stack-trace-exposure (#178, #179, #585): log exception detail
  server-side and return a generic message to the HTTP client in
  http_transport.py _handle_score (invalid JSON, bad params, scorer
  error branches).

- python.lang.security.audit.dangerous-subprocess-use-tainted-env-args
  (#227, #372): add shlex.quote() around user-supplied path arguments
  passed into shell strings in extract_ugc_features.py and
  test_bbb_e2e_v5_bug_cluster.py.

- py/file-not-closed (#677, #678): replace bare open() calls with
  context managers in test_coverage_round3.py.

- py/redundant-comparison (#427, #431): remove redundant
  assert not (x != y) lines that duplicate the preceding assert x == y.

- py/equals-hash-mismatch (#182): convert RdPoint to frozen=True
  dataclass so __eq__ and __hash__ are generated consistently.

- py/inheritance/signature-mismatch (#197): add result_dict=None
  default to EnsembleVmafQualityRunner._populate_result_dict so the
  signature is compatible with the base class.

- py/multiple-definition (#201): drop redundant assignment to
  feature_found in feature_extractor.py wildcard discovery path.

- py/str-format/surplus-named-argument (#204): remove unused
  dataset= kwarg from the format() call in routine.py.

Skipped: python.lang.security.audit.insecure-file-permissions (#373) —
  the Unix socket at 0o660 is intentional (Go sidecar node must write
  to it and runs as the same UNIX group); tightening to 0o644 would
  break the IPC channel.

Skipped: py/path-injection (#180, #181) — _validate_path() already
  resolves the path and checks it against an allowlist before any file
  operation; the data flow is secure and the CodeQL dataflow trace is a
  false positive on this allowlisted pattern.
