wald 0.1.0
First public release.
Static layer: three decided flaw classes (leakage-fit-before-split, testing-multiple-uncorrected, baserate-accuracy-imbalanced) plus a survivorship candidate. Deterministic, key-free, exit-code gated. Measured by a mutation corpus: 176 verified mutants, 0.0% false positives on 75 clean notebooks (27 real, hand-reviewed). SARIF output and agent-gate recipes (Claude Code hook, pre-commit, GitHub Actions) in docs/agent-gate.md.
The LLM narrative layer ships built but unclaimed: its quality gates need cross-provider API runs that have not happened yet. Static-only is the default and calls no API.
