+## v1.21 — Nova Deck Refinement & Pipeline Hardening (complete)
+
+> Leadership-deck refinement based on 33 review notes on the v1.20 deck.
+> Renamed the deck to the professional "Autonomous Cloud Delivery
+> Platform" framing; restructured the narrative (Problem → Solution →
+> Proof → Roadmap + Ask); removed internal provenance from
+> audience-facing slides; hardened the policy pipeline (Checkov before
+> plan, Wiz-or-Checkov on plan); moved the strategic integration
+> objective into the North Star.
+>
+> Tags run on the v1.20.x line (milestone v1.21 → tags v1.20.0..v1.20.6).
+> Flat workflow: commits on main, tags per phase.
+
+### Phase P0 — pre-execution (complete, tag v1.20.0)
+- SPECIFY → CLARIFY → RESEARCH → PLAN. Validated v1.21 requirements
+  (REQ-245..253). Established `active_milestone: "v1.21"`. Synced
+  PROJECT.md strategic-direction pillar.
+
+### Phase P1 — strategic-docs (complete, tag v1.20.1)
+- `git mv .ciagent/NO_HUMANS_THESIS.md .ciagent/AUTONOMY_THESIS.md` +
+  reframe content (autonomy in operations, not "removing humans").
+- `NORTH_STAR.md`: vision polished ("invisible" → "visible"); obj #2
+  deterministic-scoring reword; obj #3 four CTO metrics; obj #4 replaced
+  with integration objective; drop anti-goals 1,4,5; add 2 new
+  anti-goals; anti-goal #3 reworded.
+- `docs/raci.md`: 3 roles → 4 roles (add Quality Engineering; rename
+  Release Mgmt → SRE; split release attestation).
+- `docs/scope.md` + render scripts + ONBOARDING: integration framing +
+  "no-humans" → "autonomous".
+
+### Phase P2 — slides source-of-truth (complete, tag v1.20.2)
+- `git mv` all 5 deck files `nova-no-humans-platform*` →
+  `nova-autonomous-cloud-delivery*`.
+- Rewrote source of truth to 18 main + 1 appendix slides, 4-beat arc.
+  All 33 review notes applied. Removed: old Slide 10 (Capability
+  Health), old Slide 12 (Zero-Touch), Appendix A2 (Operating Model &
+  Cost). Global: tech-leadership benefits; no D-###/REQ-###/.py paths in
+  audience slides; no badges; no version in footer.
+
+### Phase P3 — marp deck + talking points + README (complete, tag v1.20.3)
+- Synthesized Marp deck from updated source; frontmatter — title
+  "Nova — The Autonomous Cloud Delivery Platform", footer without
+  version + without "Act N/5", title-slide subtitle "Product Development
+  & Citizen Developer Overview"; no badges.
+- Re-distilled talking points to 18-slide + A1 structure.
+- README updated (deck title, audience, slide count, directory layout,
+  no badge docs).
+- Theme CSS: fixed Appendix A1 table readability (explicit white body
+  on any background).
+- Tests: added v1.21 assertions (no badges, no version, 18+1 slides, no
+  D-###/REQ-###/.py paths, old files removed, default deck renamed).
+
+### Phase P4 — pipeline hardening (complete, tag v1.20.4)
+- Two-stage policy scan (REQ-250): Checkov on static code BEFORE plan
+  (fail-fast); Wiz-or-Checkov on the plan AFTER plan (never both).
+  Implemented in run_platform.sh + run_codegen.sh + run_postapply.sh.
+- `adapters/wiz/wiz_adapter.py`: added --plan mode CLI.
+- `pipelines/contract.yml`: 'checkov' stage replaced by 'checkov-static'
+  (before terraform-plan) + 'runtime-policy-scan' (after). 9 → 10 stages.
+- Tests updated; full suite 686 pass + 1 pre-existing attestation
+  failure (unrelated env issue).
+
+### Phase P5 — render + verify (complete, tag v1.20.5)
+- New mermaid diagrams: platform-pipeline.mmd/.png (slide 6),
+  telemetry-live-ops.mmd/.png (slide 9).
+- Re-rendered HTML + PPTX (20 slides, 21 media files).
+- Verify: 101 v1.21-specific tests pass; 686 full suite pass;
+  check-only pipeline exit 0; no no-humans/D-###/REQ-###/badge in
+  audience-facing deck files.
+
+### Phase P6 — final-review-ship (Final Phase, complete, tag v1.20.6)
+- Multi-file audit: git log matches `.ciagent/` discipline; deck files
+  renamed; forbidden content absent from audience-facing slides.
+- Ship: tag `v1.20.6` (final patch = milestone release). Requirements
+  marked complete; ROADMAP marked complete; CHECKPOINT cleared.
+- **Requirements:** REQ-245..253 (9 requirements, all complete).
