What shipped

_SCHEMA.md — gate_evidence_type field added to gate_checks schema with four-value vocabulary: prevented_spin | detected_spin | deterrence_only | ceremonial

_SCHEMA.md — inferred_risks field added to session_contract schema, documented in declared build fields reference

ignition.md §5 KNOWN TRAPS — Archived Traps table added (max 10 rows, no-recurrence-in-10-sessions threshold, promote-back-immediately rule)

ignition.md §5 KNOWN TRAPS — altitude rule updated: 'remove or archive' → 'move to Archived Traps, do not delete'

ignition.md §3 ORIENTATION — risk inference step added before session_contract: read files_to_read_before_writing before declaring risk_triggers, infer what the code implies

“The AI did not just build faster. The system learned how to build faster. That is the core IP.”
