CI optimization

Measure GitHub Actions wait time before changing. Preserve required checks, artifacts, and failure behavior.

Discipline

Iron Law: Capture the baseline before proposing a concrete edit.

Explicit authorization is required before destructive cleanup, paid infrastructure, dependency installation, source edits, or remote dispatch.

Red Flags — stop when you notice these:

• A check, artifact, workload, or failure path is removed to create a speed result.
• A rerun, partial job page, or changed validation contract enters the primary cohort.
• A local result or zero exit status replaces a CI comparison.
