+- **`audit --fail-on-no-sbom` gate** — *the* 0.8 feature deliverable. The observational `--sbom` tier
+  already reports SBOM presence; the remaining step is the CI gate that *fails* the build when a
+  stamped image lacks an SBOM. This **closes the enforcement ladder**: all four rungs
+  (`uncovered < stamped < signed < has-SBOM`) now carry both an observational tier and a
+  `--fail-on-*` gate. *(ADR 0029, P0.5)*
+
+- **Docs polish pass.** The docs site shipped in 0.7.0; 0.8 raises its quality bar:
+  - an **architecture presentation** — a narrative overview of the hexagon (sourced from the C4 model), not just the reference;
+  - a **richer examples section** — broaden and deepen the worked `MirrorPolicy` walkthroughs;
+  - **diagrams** woven into the prose (the committed Mermaid C4 exports, inline where they explain);
+  - **fenced code blocks** throughout — runnable, copy-pasteable commands and policy snippets.
+
+- **Schema rendering — readable generated reference (tooling, carries risk).** Distinct from the prose
+  polish above: the generated `MirrorPolicy`, config `HOUBA_*`, and scan-predicate `/scan/v1` reference
+  each render as a deep, noisy `anyOf > item N` tree (json-schema-for-humans default). Make them
+  readable — collapse the union noise, friendlier property paths, or a different renderer. Tracked as
+  its own line because the renderer swap/config is real work, not free polish.
 
 ## Deferred — revisit only on a real signal (YAGNI until then)
