The milestone is empty: 39 issues closed, 0 open. Status and Next Step
now say so, and the last six units are recorded.
Also corrects a stale caveat: Status claimed in the present tense that a
superseded CI run is recorded as skipped and rolls up green. That was
the defect #152 fixed. The narrower caveat that survives is that a
docs-only commit deliberately replays from cache (#119), so a green
check on one evidences a replay rather than an executed run.
