scripts/stage_contracts.py:
- STAGE_CONTRACTS: one authoritative definition per cognitive stage
(INWARD/OUTWARD/APPLICABILITY/ADVERSARIAL/INNOVATION/SYNTHESIS/QUALIFY)
- Each contract: required_fields (name/type/description/enum) + optional_fields
- COMPATIBILITY_ALIASES: documented field-name mappings (bounded, not open-ended)
- get_prompt_field_description(): prompt text derives from the contract
- get_aliases(): normalization aliases derive from the contract
Contract-drift tests (test_stage_contracts.py):
- All cognitive stages have contracts
- ADVERSARIAL disposition in contract (the #164 root cause: template had it, inline prompt didn't)
- INNOVATION conclusion in contract
- APPLICABILITY route in contract
- Contract-drift: validator-checked fields must be in the contract (required + optional)
- Compatibility aliases must target known fields
- Prompt derives from contract
SYNTHESIS contract promoted data_flow to required (the drift test caught it).
8 tests; full suite 1171 passed; ruff clean.
