Stage 1 — Gateway SSOT Runtime Contract Foundation — 00 Readme First

Macro: BIRTH_STAGE1_GATEWAY_SSOT_IMPLEMENTATION_AND_RUNTIME_CONTRACT_FOUNDATION Date: 2026-06-06 · Mode: EXECUTION (principal-delegate) · Live mutation: YES — additive + reversible only (3 functions, 3 tables, 5 seed rows, 19 views). birth_registry NOT mutated. fn_birth_registry_auto NOT changed.

Verdict

PASS. Moved from DANGEROUS_BIRTH_DOT_EXECUTION_FROZEN + GATEWAY_SSOT_DRIFT_DETECTABLE + QT001_QT002_IMPLEMENTATION_READY to BIRTH_GATEWAY_SSOT_RUNTIME_CONTRACT_LIVE + SHARED_POLICY_IDENTITY_REGISTER_FOUNDATION_READY_FOR_QT001_QT002.

What is live now

• Runtime contract registry birth_gateway_release_registry (release v1-stage1-2026-06-06, semantic SHA-256 + normalized-md5 for 5 gateway/helper fns) + drift guard + integrity dashboard — one live place to check "which gateway contract is current", fail-closed.
• Shared foundation functions: fn_birth_policy_decision, fn_birth_resolve_identity, fn_birth_register — deterministic, no-write / dry-run-default, fail-closed, never invent identity.
• Fail-closed scaffolding: birth_admission_permit + birth_backfill_ledger (empty).

What was deliberately NOT done (safe branch)

• Live trigger gateway fn_birth_registry_auto left byte-identical (integration Option A — parity-guard-only). QT-002 live path unchanged. Full thin-wrapper integration (Option C) + setup-DOT strip staged for Stage 2 under T2 review.
• No QT-001 backfill. No DOT unfreeze. No trigger/source/owner/RP/REALRUN/event change.
