FACTUAL ACTIVITY RECORD · An activity record based on work that took place

Promoting a candidate release in stages

Advancing from a no-traffic candidate through limited validation to production

Activity period:

Purpose

Safe broker publication required a stage where a fixed candidate could be validated with limited exposure instead of combining placement and traffic switching.

Implementation

Preparation, no-traffic candidate placement, limited-traffic validation, renewed preparation, and full traffic switching are separate phases. A fixed candidate tag is bound to the artifact digest, and each phase validates prior evidence and expiry to reject out-of-order operations or candidate substitution.

The implementation preserves the ordered gates from prepare-artifact verification through candidate apply, canary, and the next handoff. Source runs, artifacts, identities, URLs, secrets, and concrete commands are omitted.

What was confirmed

Verification results

Checks confirmed release-phase order, candidate identity, and the gates from limited traffic through full switching.

At the cutoff, production candidate placement and traffic switching had not been executed.

Basis for completion

The work was complete when the release gates separating placement, limited validation, and full switching were implemented and verified while preserving candidate identity.
