Deployment promotion gate: Mandatory deployment approval is ignored · case 01

Mandatory deployment approval is ignored.

Verified by executionVariant 1 · 9 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The implementation substitutes True for (not state['approval_required'] or state['approved']), so mandatory deployment approval is ignored.

THE FAILURE

The implementation substitutes True for (not state['approval_required'] or state['approved']), so mandatory deployment approval is ignored.

Unsuccessful approach: The attempted repair substitutes state['approved']. Fixture 1 still yields False instead of True.

Case contract

Promote only if desired revision matches tested revision, all required checks pass, minimum healthy replicas is reached, approval is present when required, and no freeze is active.

Why this case matters

An offline model of deployment promotion gate, suitable for testing build and release tooling without external services.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 9 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.

Observations recorded using Python 3.12.14 at 2026-09-29T14:38:35.872090+00:00.
