v1.5.7 Technical Notes
2026-09-19 · Durable Find the Word FTUE completion, explicit practice-board provenance, and idempotent historical profile reconciliation.
Tutorial State
- The WOTD full-word result step persists its completion flag when earned, before dismissal or navigation can interrupt it.
- First-time practice uses an explicit client-only session, so it cannot consume or complete a server-authoritative Daily attempt.
- Deterministic answer boards carry an explicit mode-FTUE practice source marker for runtime assertions and future telemetry wiring.
- A dry-run-first migration reconciles profiles found in retained authoritative winning full-word replays while preserving existing onboarding flags.
Regression Coverage
- Registry coverage locks completion persistence to the earned feedback step.
- Page coverage requires a successfully started protected practice before the guaranteed board can be installed.
- Browser coverage verifies the completion flag exists before the player dismisses the result feedback.
