# Phase 4 checkpoints Phase 4 starts from `f696f23` on `codex/ui-redesign-phase4`. The 57 preservation contracts in [Phase 2](../phase-2/PRESERVATION_MATRIX.md) and the [Phase 3 impact matrix](../phase-3/PRESERVATION_IMPACT_MATRIX.md) remain authoritative. - [P4-01 semantic colors, focus and loaded fixtures](p4-01/README.md) - [P4-01 preservation and visual evidence](p4-01/TRACEABILITY.md) - [P4-02 named controls and modal state](p4-02/README.md) P4-02 is locally validated after `115441a` and the separate documentation restructure `682a302` on the same Phase 4 branch. Its approved scope is named controls and modal/loading state; P4-03 remains unstarted. No route/layout redesign, B07, backend/schema behaviour changes or production deployment is included. F04 remains open pending actual production ingress evidence.
