Prior session committed AZ-619 (Phase A of AZ-618) as 8abfb02,
transitioned the tracker, and archived the spec, but did not write
the batch report. Content reconstructed from git show + the AZ-619
task spec + the prior _docs/_autodev_state.md sub_step.detail.
No code change. Pure audit-trail housekeeping.
