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

Adding prepare and apply gates to infrastructure changes

Fixing source, artifact, and state so only the reviewed candidate can advance to application

Activity period:

Purpose

Production infrastructure changes needed separate stages that fixed source, artifact, and state so the reviewed plan could not diverge from the applied target.

Implementation

Read-only preparation and mutating application are separated by identity and procedure. Preparation records the source revision, artifact digest, state lineage and serial, inputs, and phase; application accepts only the candidate carrying the same evidence. Expiry and consistency checks reject stale plans or substituted artifacts.

The implementation rechecks the plan, variables, state, and expiry fixed during prepare before apply. Repository, commit, run, and concrete target checks are omitted from the public account.

What was confirmed

Verification results

Checks confirmed prepare/apply separation, candidate-evidence consistency, and expiry rejection.

At the cutoff, an application run against the live environment had not been verified.

Basis for completion

The work was complete when the gate linking a reviewed candidate to its application target was implemented and checks rejected state or artifact mismatches.
