# Coverage Matrix — build-feature skills × fleet properties (TK-12025)
_Generated 2026-09-22T20:44:22Z · read-only distribution audit_

## Axes
- **Properties:** 75 standalone-node fleet microsites (authoritative source: `dw-fleet-registry.json`). 74 have a local repo scanned; 1 NOT-MEASURED (no local repo).
- **Features:** 41 detectable web build-features across 4 groups. NOTE: the ticket cited "64 build-feature skills" but recorded no list (empty body); this axis is the *detectable-fingerprint* operationalization — drop-in UX-primitive skills + `_shared` deployed components + Steve's standing storefront-feature rules. Membership is listed below and fully auditable.

## Gap highlights
- **Sites running ZERO tracked features:** 1 — wallco-ai
- **Features NOT deployed anywhere (adoption 0):** 9 — `ux-primitives-base`, `modal-rig`, `page-flip-ui`, `kv-list`, `bookshelf-catalog`, `oversized-cursor`, `spin-viewer`, `nav-agent`, `three-view`
- **Drop-in UX-primitive family total deployments:** 71 across 14 primitives (the Bundle-B family — this is the adoption headroom the coverage audit was built to expose).

## Feature axis membership (the exact denominator)
- **SEO / meta / page** (5): `sitemap-robots`, `structured-data-jsonld`, `social-meta-tags`, `analytics-ga`, `basic-auth-viewer`
- **_shared components** (13): `corner-nav`, `corner-nav-accordion`, `hero-4grid`, `universal-promo-banner`, `admin-catalog`, `microsite-aesthetic`, `rail-match`, `dw-theme-nav`, `color-isolate`, `nav-agent`, `three-view`, `image-proxy`, `site-config-shared`
- **drop-in UX primitives** (14): `toast-notify`, `skeleton-loader`, `empty-state`, `command-palette`, `copy-to-clipboard`, `ux-primitives-base`, `modal-rig`, `page-flip-ui`, `bento-grid`, `kv-list`, `bookshelf-catalog`, `age-adaptive-theme`, `oversized-cursor`, `spin-viewer`
- **storefront standing features** (9): `sort-select`, `density-slider`, `created-date-chip`, `href-drill`, `pairs-well-with`, `new-arrivals-rotator`, `substitutefinder`, `rotating-hero`, `memo-sample-order`
