# Exxat DS consumer app

Cursor always injects this file. Keep it short. Do not paste the full handbook here.

**Always-on rule:** `_constitution.exxat-ds.mdc` only. Product, routing, brief protocol, and copy attach by glob or on demand.

**Surface router:** `exxat-surface-router` / `exxat-ui context <surface>` / `node scripts/agent-context-router.mjs <surface>`. Read the packet. Do not open `exxat-token-economy` or `exxat-senior-ux` unless IA is undecided.

**§-numbered MUST/MUST NOT + ship checklist:** `docs/exxat-ds/handbook/agents-handbook.md` (on demand). Open it only for architecture or the §13 checklist.

**Shared primitives:** `@exxatdesignux/ui`. Product code lives under `src/`, `components/`, and `lib/`.
