Milestone v1.12 complete. All 6 requirements satisfied:
- REQ-129: adapter dedup defect fixed (CAP-013 Verified).
- REQ-130: 2 regression-probe bugs fixed (CAP-017/018).
- REQ-134: lifecycle tests plan-only default + ACDL_LIFECYCLE_MODE flag.
- REQ-131: decks match CAPABILITY_INVENTORY.md (22/22 Verified, zero
  stale claims except the honest 'v1.10 status is closed' disclosure).
- REQ-132: decks reflect v1.11 architecture + roadmap (v1.10 no longer
  NEXT); version refs bumped to @v1.12.
- REQ-133: A6 (real cost figures + pre-mortem) + A7 (stateless adapter +
  lifecycle pipeline); HTML re-rendered; PPTX exported for the release.

Verification: 522 tests pass; 22/22 capabilities Verified (D-091);
run_platform.sh --check-only green; run_ci.sh green; ci-doc-verifier
grep clean; multi-persona review clean (P1 remediated).

ROADMAP.md v1.12 section added; v1.11 marked complete; config.json
status -> complete, ship_tag v1.12.0. Version refs @v1.11 -> @v1.12
(decks re-rendered). PPTX in /tmp/v1.12-release/ for the Gitea upload.
