+## 0.6.0 — 2026-08-15
+
+### Frozen — ITC-CAP draft; AttributeValueType catalog; joinable review
+
+**Change.** Canon 0.6.0 is the freeze cut.
+
+- **ITC-CAP** promoted from `proposed` to `draft`. Contract schemas
+  published: `capability.schema.yaml` (catalog) and
+  `capability-record.schema.yaml` (requirement/provision records).
+  `make validate` enforces CAP-R8 on the catalog.
+- **Capability-review surface:** `info-tech-canon capability-review PATH`
+  and `GET /capability-review?path=` join a consumer record to the live
+  catalog (OQ-6 / ITC-WP-0014 T06).
+- **Mappings:** `infospace/mappings/capability-anchors.yaml` formalizes
+  the assimilation mappings (T03).
+- **Landscape §11.4** and **Kernel Map §4.14** now point at ITC-CAP (T05).
+- **AttributeValueType** catalog under ITC-DATA
+  (`models/data/attribute-value-types.yaml`) from
+  `demand/AttributeValueTypes.md` (ITC-WP-0013). citation-evidence
+  alignment note published.
+
+ITC-WP-0013 and ITC-WP-0014 are finished. T04 (small-saas illustration)
+remains optional and does not block the freeze.
+
+**Rationale.** One consumer cycle has refined the capability model; a
+second consumer needed a closed capture-type catalog. Further shape
+change of ITC-CAP needs a new minor. 0.6.0 is the version to sit on.
+
+**Breaking:** no capability id or AttributeValueType id invented as a
+break. New catalogs and schemas only.
+
+**Validation.** `make validate` 0 errors / 0 warnings; `make test` 23 passed.
