[AZ-455] Cumulative review batches 07-08 (cycle close, PASS_WITH_WARNINGS)

K=3 cadence cumulative review for the final 2 batches of
Phase A. Verdict: PASS_WITH_WARNINGS (0 Critical / 0 High;
F-CUM-5 lifts production-drift backlog to 23 entries;
F-CUM-4 long-running soak tagging carries over).

Phase A is now COMPLETE: 25 test tasks delivered across 8
batches; 0 production source mutations; 26/26 ACs covered
in this window; 100% cumulative AC coverage; 29 commit-time
static gates active.

Next autodev action: Step 7 (Run Tests).
