# 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)
- [P4-03 builder preview keyboard boundary](p4-03/README.md)

P4-02 is locally validated after `115441a` and the separate documentation restructure `682a302` on the same Phase 4 branch. P4-03 follows the P4-02 checkpoint `ebd4a3e`, adding preview keyboard access and preserving focused panes through viewport transitions. P4-04 remains unstarted. No route/layout redesign, CV margin/template rendering correction, B07, backend/schema behaviour changes or production deployment is included. F04 remains open pending actual production ingress evidence.
