Historical V2 — Canonical Current Schema Contract (L0)

Diese Artefakte materialisieren den CURRENT VERIFIED PRODUCTION SCHEMA CONTRACT als kanonische L0-Autorität (D1/D2 Remediation, forward-only).

  • historical_v2_schema.sql — schema-only PostgreSQL-Contract (kein DML/Secrets/volatile Artefakte)
  • historical_v2_schema.json — maschinenlesbares kanonisches Modell
  • historical_v2_schema.sha256 — deterministischer SHA-256-Fingerprint
  • Kanonischer Fingerprint: b49f64337ffafc0e73d46e009aa802cd0172d59421b7df61d3eb198775c1986d

Dies ist KEINE historische Migrationskette. DO NOT INVENT HISTORY: der L0-Contract beansprucht ausschliesslich CURRENT PRODUCTION TRUTH (§1). Historische Artefakte (Wave1 6983526da3ca51fd2ececffbef0ccbd66b048a3d11c228000011aaba3e1d6bc5, WaveD 7aa4e2a10c98fa327e000a49f6a497efb5814c8808dba429dfebfc90c544a02b) bleiben unverändert.

Semantic Overrides (§4):

  • last_successful_chunk = timestamp with time zone (Production+Owner; WaveD-historical text bleibt immutable Evidence)
  • interrupt_reason = text (preserved, origin unknown, do not remove)
  • technical_quality = text nullable default 'VALID' (historical provenance debt OPEN)
