RELEASE REVIEW WORKSPACE

Release evidence, in one view.

Relay gathers the code change, policy decision, and verification note into one reviewable record before a deployment moves forward.

WHY IT CHANGED

{activeFile.note}

WORKBENCH / POLICY

Read the decision, not a dashboard.

01INPUT

Change context

Files, owners, and the release intent stay attached to the decision.

02RULE

Review policy

Each requirement names the evidence it expects and the reason it exists.

03OUTPUT

Release record

The final record shows what passed, what changed, and who can revisit it.

VERIFICATION / LIVE SAMPLE

Make the release explain itself.

Run the sample policy check to update this release record. The interaction is local to this concept preview.
