+# @refkit/provider-nailbook
+
+## 0.1.0
+
+### Minor Changes
+
+- 17469ad: New keyless provider `@refkit/provider-nailbook` — image references from Nailbook
+  (nailbook.jp), a large Japanese nail-design catalog. Recall is best with Japanese tag
+  words (マグネット, ニュアンス, ちゅるん…). Results are discovery-class: no per-item
+  license metadata, so each carries `license: 'unknown'` + `rehostPolicy: 'thumbnail-only'`
+  and gates to `needs-review` (never auto-allowed) — surface the CDN thumbnail only, never
+  rehost the original.
+
+  Rather than scraping the client-rendered `/design/` list HTML (whose embedded bootstrap
+  carries photo IDs but no image URLs), the provider calls the same JSON endpoint the site's
+  own frontend uses (`POST /api/web/photo/search`), returning full photo objects in one
+  request. Each `search()` makes exactly one request with no multi-page fan-out.
+
+  `@refkit/mcp` boots Nailbook in its zero-config keyless default set.
+
+- 431d834: Provider resource declarations: open `ResourceKind` vocabulary with optional
+  `kinds` + `description` on providers and `kind` on references; declaration-gated
+  kind routing (a kind-filtered search skips providers whose declared `kinds`
+  lack the value, with a new `unsupported-kind` skip reason) composed with the
+  existing `sources` id filter; MCP tool schema, per-provider source list, and
+  the `modalities` / `media.kind` enums now derived from registered provider
+  declarations at startup.
+
+  Note: the MCP `modalities` input enum is now deployment-dependent (derived

+
+- 431d834: Provider resource declarations: open `ResourceKind` vocabulary with optional
+  `kinds` + `description` on providers and `kind` on references; declaration-gated
+  kind routing (a kind-filtered search skips providers whose declared `kinds`
+  lack the value, with a new `unsupported-kind` skip reason) composed with the
+  existing `sources` id filter; MCP tool schema, per-provider source list, and
+  the `modalities` / `media.kind` enums now derived from registered provider
+  declarations at startup.
+
+  Note: the MCP `modalities` input enum is now deployment-dependent (derived
+  from the registered providers). A request naming a modality no registered
+  provider supports is now rejected at the schema boundary — previously a
+  fully-unsupported request threw at search time, and a mixed request (e.g.
+  image+audio against an image-only deployment) returned the supported subset.
