An AI SDLC release gate must prove what it accepted

A passing check and a release approval can refer to different things. A practical acceptance record connects the candidate, policy, environment, evidence, and decision.

Consider an illustrative release: a reviewer approves candidate A, a repair produces candidate B, and the deployment job sees an approval flag left over from A. Every component may report success while the approval refers to a different artifact. The engineering problem is the relationship between the records. More persuasive review text cannot repair that relationship.

Claude Academy’s hooks lesson shows how to move policy into enforced controls. It explicitly covers managed settings, sandboxing, and the limits of its configuration examples. Its small approval-variable example is a starting illustration. For a consequential release, I would replace a bare flag with a decision authenticated by the release system and bound to the candidate it covers.

Name the subject of the decision

The acceptance record below is an original LockedIn Labs implementation pattern. It can be represented in a release service, CI attestation, or another governed record store. The format matters less than the system’s ability to validate the relationships and reject a mismatch. A Markdown worksheet is useful for design; enforcement needs to occur where the action is authorized.

What a release decision should identify

Accepted scope: The authoritative requirement, allowed behavior, affected systems, and acceptance-policy owner.
Candidate identity: The source revision and deployable artifact digest. Include dependency and runtime configuration identities where they affect the accepted behavior.
Verification context: The verifier workflow, test or eval set, thresholds, relevant environment, and execution identity. Preserve actual results and failed attempts.
Disposition: Approve, hold, or reject; the named human release authority and policy applied; the permitted environment and action; conditions and expiry.
Operational reference: The observed deployment, owner, recovery procedure, and the retained records needed to investigate or reverse the change.

This develops the published CQ-10 evidence requirements and the informative per-change evidence kit. The full record above is our implementation proposal; it is not presented as a quotation from a single CQ clause or a claim of independent certification.

A change to the gate is a change to the decision

An agent may correctly discover that a test is obsolete or a threshold is poorly chosen. The answer is a reviewed policy change with its own rationale and evidence. The authoring identity should not quietly edit the protected acceptance controls and then use the resulting green status to approve its product change. Separate authority makes legitimate updates possible without erasing the distinction.

Anthropic’s eval lesson reinforces this point by treating models, prompts, instructions, skills, and hooks as configuration worth evaluating. A code diff is only part of the candidate when behavior also depends on those inputs. Record the versions that matter to the task; avoid a sprawling inventory of details that nobody can connect to an acceptance decision.

Independence is also an access property. A fresh context or different model can improve critique, but it does not by itself prevent a verifier from changing source or granting approval. Inspect effective permissions, the identity that reports a required status, and who can alter or bypass the policy. Keep probabilistic review findings distinguishable from executed deterministic results.

Exercise the paths that should not succeed

Release-gate challenge cases

Use synthetic candidates in an isolated release environment. Record the observed result and control owner for each case.

Change the artifact after approval: the old decision must not authorize the replacement.
Present an expired approval or an approval for another environment: the action must be refused.
Cancel, skip, or omit a required check: the release must remain blocked.
Attempt to change protected tests or thresholds with the authoring identity: the unauthorized change must fail.
Replay an authorization outside its allowed action or use conditions: the release service must reject it.
Exercise an approved exception, then its expiry: the recorded policy must return to the required restriction.

These are proposed acceptance cases, not reports of tests we ran against Anthropic’s products. Their value is local: they reveal whether your actual integration connects authorization to the right object. Passing a shell demonstration cannot establish the behavior of a separate deployment service, credential path, or administrator bypass.

Retain enough evidence to explain the outcome

The deployment receipt should identify what actually ran. Keep it with the accepted candidate, decision, and supporting results under an appropriate retention policy. Test whether an investigator can reconstruct the release after short-lived CI logs disappear. Retention must also respect data boundaries; a useful evidence record does not require copying secrets or customer payloads into an article, repository, or unrestricted log.

Recovery needs its own acceptance evidence. A rollback command exiting successfully does not prove that business state was restored. Depending on the system, queues, external messages, data migrations, or transactions may require reconciliation or compensation. Define the observable recovered condition and the point at which automation must stop and hand control to the service owner.

Read the playbook comparison for the lifecycle context, and Model judgment is advice. Never a gate. for the distinction between review and acceptance authority.
