and live proof with the exact `OpenAgents.BuildInfo` allowlist entry. The

  broader allowlist remains unchanged and disabled outside tests.

The implementation is ready for an exact-commit local gate. Keep every deploy

lane disabled until Gate 12 provides an isolated distributed staging fleet and

an infrastructure-specific rolling provider. No staging or production

environment changed during this gate.

Gate 11 is complete locally on exact implementation commit

`2e1c9240d0b172501a93bef7b02e934a63b447ae`. The exact-SHA release gate passed

test and production compilation, precommit, 14 distributed tests, 17 browser

tests, 42 focused direct-transaction tests, live upgrade/downgrade/re-upgrade,

interrupted-install recovery, four rolling-replacement tests, 68 contract

tests, and packaged startup with zero automatic retries. The immutable local

image is `sha256:56e472ce2ac3a967e21f6906c08f87933228d74e6f26d3c041661f180872d472`.

See the [Gate 11 evidence](evidence/gate-11/2e1c9240d0b172501a93bef7b02e934a63b447ae/README.md).

Keep every deploy lane disabled until Gate 12 provides an isolated distributed

staging fleet and an infrastructure-specific rolling provider. No image was

pushed, and no staging or production environment changed during this gate.

## Gate 12: Build an isolated staging environment

# Gate 11 release fallback evidence

Date: 2026-08-20

Implementation SHA: `2e1c9240d0b172501a93bef7b02e934a63b447ae`

Gate 11 passed locally on the exact implementation commit. This evidence set

is content-free and contains no credentials, database URLs, hostnames, private

repository content, conversation content, or staging data.

## Evidence

- `release-gate-receipt.json` is the immutable result copied from the owned

  exact-SHA release gate. Test and production compilation, precommit, all 14

  distributed tests, 17 browser tests, 42 focused direct-transaction tests,

  four rolling-replacement tests, 68 contract tests, and packaged release

  startup passed without retries.

- `relup-proof.json` records the checksums for explicit `0.1.0` and `0.2.0`

  release artifacts and the generated two-way relup. The exact-SHA gate also

  proved upgrade, downgrade, and re-upgrade on a live packaged node and

  recovery after interrupting an install beyond its point of no return.

- `rolling-and-image-proof.json` records the local image digest and the rolling

  recovery cases exercised by the exact-SHA gate.

The release startup and relup drills used one newly provisioned disposable

PostgreSQL role and database. No image was pushed to a registry, and no staging

or production deployment occurred.
