First release — a complete, differential-verified Python port of the SpecForge validator.
All four output layers match the reference engine byte-for-byte:
- structural — schema checks (presence, format, duplicate-order, entity counts)
- scoring — 53-entry rubric, tier weights, topology penalties, cascade floors
- cross-validation — 13 consistency checks
- guidance — composite-pattern prose suggestions
Deterministic, no-LLM. pip install crucible-forge → import crucible.
Requires Python ≥ 3.11.
