+# V2 Provider Promotion Field Evidence
+
+Date: 2026-08-12
+Scope: shared-staging signed receipt promotion, production read-only verification, and the two-node control drills.
+
+## Result
+
+The dynamic Provider promotion gate passed on two independent nodes. Both nodes reported the same immutable release, receipt, signing key, and image digest. Receipt-key revocation propagated to both nodes in 2.64 seconds, within the 60-second drill SLA. The kill switch was restored to the fail-closed state (`true`) after the canary.
+
+This evidence does **not** authorize public traffic. The production `edge` container was not started, DNS and traffic were not changed, and the production readiness gate is intentionally blocked by the restored kill switch. Identity execution, support access, and destructive identity-write APIs remain disabled.

+The named legal approval was verified offline against the exact approved payload `c3246b5b7ba5b98604acf3e7f49c3186ad79a7e77426d272c0e2745e4e230702`. The approval covers 10 knowledge cards, 18 Provider results, and 31 product golden assets.
+
+## Field Evidence
+
+| Check | Result | Local evidence SHA-256 |
+| --- | --- | --- |
+| Initial two-node kill switch | passed; both nodes `blocked` | `c462064c9fd99b2fd02bec2b76f8a506abf07e8206bd4ed27e1135e2b8676d` |
+| Receipt key revocation | passed; both nodes observed `receipt signing key is revoked` | `ea11e27302b9852e4e9387e871fd8260bcb83129b9817443b4373f1752d91008` |
+| Two-node read-only canary | passed; both nodes `ready`, acceptance verified, release allowed | `28300c61073cedb5ee4af2f6b1ee85cba7e24290d00b23f6a9f754a0708e5631` |
+| Final fail-closed restore | passed; both nodes `blocked`, kill switch active | `b048ba2c03a53e8ee87e107b0cfda649eb6e7c12102892726dd2b8f24ef1d6d` |
+
+The revocation drill changed only the receipt keyring in memory on each node, restored the original bytes in a `finally` path, and verified the original keyring SHA-256 on both nodes as `1af246affb53f244681723ea328d49babcfdeedff24fdee48cfc50160ecf388d`.
+
+The second node restored the AI PostgreSQL dump into an isolated canary database and enforced `default_transaction_read_only = on`. Its AI API was bound to loopback only and reached through the WireGuard/SSH verification path; no public listener was created.
+
+## Backup and Recovery
+
+Backup `backup-20260811T152805Z` completed with three PostgreSQL dumps, Contract file archive, manifest checksums, and three one-time restore databases. The restore verifier used database-owned markers `contract_api_alembic_version` and `ai_platform_alembic_version`, plus a public-table count for operations. Temporary restore databases were removed.
+
+## Code Regression
+
+- Infra Provider/promotion and production release tests: `72 passed`.
+- Contract Web API base-path regression: `6/6 passed`.
+- Contract Web TypeScript typecheck: passed.
+- Python compileall and `git diff --check`: passed.
+- Production Contract and AI APIs, workers, PostgreSQL, Redis, and MinIO: healthy at closeout.
+- Public `edge` container: absent by design.
+
+## Remaining Release Boundary
+
+The Provider promotion evidence is closed. Formal public production launch remains a separate decision: first complete the production Web/edge and TLS/DNS cutover review, observability and rollback sign-off, and the independent support-access gates (external IdP/MFA, session binding, real-resource TOCTOU, immutable per-request audit, privacy/legal approval). Until then, keep the kill switch active and do not add or enable an identity `execute` API.
