Handing off the broker image as an immutable artifact
Fixing the build source and digest so only a current candidate advances
Purpose
The broker image advancing toward production needed to keep the built content identical to the content consumed by later stages.
Implementation
A dedicated build procedure creates the image from the selected source, registers it in one fixed store, and captures its immutable digest. Handoff evidence includes the source, digest, creation time, and expiry, and downstream stages compare the digest rather than a mutable tag.
The implementation shows source verification, a dedicated identity, immutable image creation, digest verification, and a short-lived handoff in order. Concrete commands and delivery identifiers are generalized.

What was confirmed
Verification results
Checks confirmed the relationship among build target, storage destination, digest, and expiry.
At the cutoff, an actual image build and registration in the external store were not verified.
Basis for completion
The work was complete when the build result was identified by immutable digest and the expiring evidence gate was implemented and verified.
