test-init.ts

// Tests for the Phase 15 `init` tool core (issue #64): idempotent onboarding —
// bind the repo, scaffold the convention projects, return live re-keyed IDs.
//
// Covers: fresh bind (default Foundations + UI), idempotent re-call (no dupes,
// stable IDs), custom project list, adopting an existing on-disk binding from a
// session that booted unbound, and the design-system token-count detection.
//
// Usage: npx tsx test-init.ts
