Verification

gofmt -w cmd internal
go test ./...
openspec validate bootstrap-job-tutor-platform --strict

Additional smoke check:

• Diagnostic create/answer followed by readiness-map and next-challenge reads returned readiness 75, one concept, and a typed challenge.

Deferred

• Frontend readiness visualization.
• Persistent campaign and streak state.
• Multi-concept cluster graph beyond simple stable-count boss unlock.
