 - **v1.13.2 (complete, tag `v1.13.2`):** presentation badge cleanup + platform architecture diagram — removed all `testing`/`agentic` maturity badges from both decks (only `planned` retained); added a new Slide 3 "The platform at a glance" with a shared high-level logical architecture diagram (consumer surfaces → contract → central pipeline → cross-cutting components → AWS) to both decks; renumbered subsequent slides 4–11; synced talking points + README. Docs-only NFR patch (no code changes).
 - **v1.0 demo URL:** https://git.cloudinit.dev/continuous-intelligence/acdl-evidence/raw/branch/main/index.html
 - **v1.23 (complete, tag `v1.22.6`):** Nova Deck Cleanup & Python PPTX — consolidated the deck to a single source-of-truth `*-marp.md` (deleted the plain `.md`; speaker notes + talking points embedded as Marp HTML comments); restored the clean S&P visual style (Marp `default` theme + inline `style:` block, matching the old `the-developer-experience.html`); retired `nova-sp-theme.css` from the render path (kept as reference); base64-inlined all images in the HTML for redistribution (`scripts/inline_images.py`); built a parallel structured editable S&P-themed PPTX generator (`scripts/render_pptx.py` via `python-pptx`); restyled benefit callouts (`<div class="benefit">`); targeted ~20-30% word-count trim on 8 verbose slides; removed the term "penetrate" repo-wide. 13 requirements (REQ-263..275), 6 phases. 43 tests pass.
-- **v1.24 (active):** Consumer Guide Accuracy & Env-Promotion Lifecycle Enforcement — fixes 5 consumer-guide accuracy issues (stale contract-fields table, inconsistent caller examples, misleading "dev only" apply phrasing, Step 8 promotion contradicts the per-env section, stale `@v1.19` reference wording) and adds platform-enforced destroy-on-environment-change: when a consumer edits `environment:` on a stable `contract.id` (Shape A promotion), the platform detects the change via the `nova-contracts` DynamoDB table, destroys the prior env's Terraform state (`spike/{id}/{prior_env}/`) before building the new env, and fails closed if the destroy fails (no orphan path). The per-environment caller-workflow path (Shape B) remains supported. New `core/env_transition.py` module. 15 requirements (REQ-276..290), 4 phases. Feature milestone; tags on v1.23.x line.
