+# Phase 8 Handoff — Interactive Prototype and Usability Testing
+
+Phase 8 is test-ready.
+
+Use `08_INTERACTIVE_PROTOTYPE_USABILITY_TESTING_v1.0.md` as the authoritative research specification, `prototype/` as the clickable test build, and `DECISION_LOG_v8.0.md` as the cumulative decision record.
+
+The prototype provides:
+
+- EN/FR/AR content with true Arabic RTL;
+- Light/Dark/System selection with persistence;
+- context-preserving locale changes;
+- demo form validation, simulated service failure, confirmation, and reset;
+- four-step product tour;
+- mobile navigation with focus containment, inert background, Escape handling, and focus return;
+- session-local, non-PII research events and export in `?test=1` mode.
+
+Research must begin with three pilot sessions, then the balanced core and accessibility cohorts defined in `PARTICIPANT_PROFILE_v1.0.md`. Do not mark Phase 8 accepted until the thresholds in `SUCCESS_METRICS_v1.0.csv` pass and every Critical/High issue is fixed and retested.
+
+Unresolved product, recruitment, market, analytics, CRM, legal, and content matters remain in `OPEN_QUESTIONS_v1.0.md`.
