Four test files covering the modules with zero or near-zero test coverage: - scripts/qc-flag/test_lean_qc_flagger.py (55 tests) Covers all pure helpers, code-line detection, QCIssue/FileResult classes, and all 5 check functions (structural, naming, Q16, proof quality, deps). - 4-Infrastructure/shim/test_braid_diat_codec.py (22 tests) Covers Q0_2 encode/decode, ChiralityDIAT roundtrips and verify_b, MountainPacked dict↔bytes, BraidResidualPacked bracket↔bytes. - 5-Applications/tools-scripts/llm/test_emitter_utils.py (33 tests) Covers sha256_bytes, canonical_json_bytes, repo_relative, safe_slug, timestamps, context bundles, message building, extract_answer, auth guard, and verify_receipt schema rules. - 4-Infrastructure/shim/test_validate_rrc_predictions.py (28 tests) Covers require_path, parse_equation, build_proof_metrics, build_receipt with all domain mappings, and MATH_* constant sets. Build: all 138 tests pass (pytest), py_compile clean Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Co-authored-by: Allaun Silverfox <bigdataiscoming+9i37y6j2@protonmail.com>
