Summary

After #189–#191, Replay stages layout and paint before installing a replacement view. When a resize or replacement needed to reveal recovered focus, finish_update called back into settle and reentered finalization. Command-driven focus also applied the same scroll updates separately.

Apply focus reveal offsets through one helper. During finalization, complete the optional second layout and focus recovery in place, then refresh pointers and publish the generation and its semantic observation. This preserves the public API, Replay v1/v2 encoding, focus reveal policy, and the step commit and rollback boundaries.

Candidate review

Area	Evidence	Scope and tradeoff
Runtime	ReplayPlayer::finish_update reentered via settle, and reveal repeated the offset writes.	Addressed here. Preserve both focus recovery passes when a second layout is needed and publish only after pointer refresh.
Widget	#186–#188 consolidated numeric draft parts, axis adjustment and geometry lookup. SplitPaneDispatcher::dispatch and ScrollbarDispatcher::dispatch still have similar move, release and cancellation branches.	Leave drag handling with its controls until a shared contract is clear. Capture and geometry invalidation differ.
Style / Paint	build_paint_list converts fill, fallback and opacity within the traversal and emits backend-independent commands.	Revisit at the next fill extension. Extracting the conversion must preserve visibility and draw order.
Tests / CI	The prior hosted Core contracts step took 299 s. The current local CTest phase took 27.72 s, with replay_serialization at 27.69 s.	Measure serialization fixture setup before considering any change to coverage. Hosted end-to-end and local test-only timings have different scope. Prior run

Verification

• Windows x64 Debug Core contracts passed 64/64, including Replay, host updates, serialization and offscreen runner. The reused build took 0.35 s to configure, 9.80 s to build and 27.72 s to test with two build workers and four CTest workers.
• The window-free Hierarchy / Inspector smoke passed in 184.30 s.
• Changed-file clang-format 23.1.1, documentation, release metadata, the 28 CI selection checks and git diff --check passed.
