v0.4.0 — heuristic auto-fix proposer

[0.4.0] — 2026-05-29

Added

• Heuristic auto-fix proposer — scripts/eval/lib/autofix.sh attaches .fix_proposal to every FAILED check whose failure mode is mechanically diagnosable: output_contains, output_not_contains, jq_path_contains, file_exists, shell (exact / min / regex). Each proposal carries kind, confidence, instruction, patch_snippet, and auto_apply: false. llm_judge and unknown kinds yield fix_proposal: null — the harness won't guess prose. Gated by EVAL_AUTOFIX (default 1). (PR #13)

Verified

• 11 test suites green (v0.3.0's 10 + autofix).
