- Move copilot history and CSV to docs/archive/
- Add docs/product/ (SSP, intermediate, genre packs) and engineering/adrs/
- Rename all spaced/special-char doc paths to kebab-case
- Nest competitive GTM under docs/gtm/competitive/
- Point README and NORTH_STAR at CANONICAL_STRATEGY
- Leave code/ unchanged for later monorepo Phase B

+# Genre packs
+
+Generic business fields are scaffolding. Durable differentiation is **genre-specific primitives** — structured tools and schemas that match how a vertical actually works.
+
+## Planned early packs
+
+- Auto repair  
+- Beauty  
+- Home services  
+- Tourism activity (especially with destination pilots)
+
+## Detail source
+
+[Canonical Strategy](../strategy/CANONICAL_STRATEGY.md) (§5.3).
+
+## Repo note (future)
+
+Genre packs will live under top-level `genres/` in a later monorepo phase. Product intent is documented here first.
