Context
Phase 542 through Phase 545 recorded the whiteboard primitive model, renderer/hit-testing, persistence/schema, and Cookbook/screenshot proof gates as docs/tests-only slices. The PR stack is green but still review-blocked, so the next safe slice should not start runtime whiteboard implementation or widen parity claims.
Scope
Refresh the React Flow parity roadmap after Phase 545 by:
- recording Phase 545 as the latest whiteboard proof-route gate;
- replacing stale future-candidate wording for Phases 542-545 with completed/stacked gate status;
- defining the next tracker-backed follow-up candidates after the current stack, including one model implementation skeleton candidate and one renderer/persistence/Cookbook sequencing candidate;
- keeping stacked PR order explicit.
Out of scope
No runtime behavior changes, no public API changes, no production model/schema changes, no renderer-layer changes, no screenshot manifest expansion, no Avalonia pointer coordinator edits, no UI redesign, no drawing tool implementation, no eraser behavior, no toolbar work, no retained API removal, and no full React Flow whiteboard parity claim.
Dependency
Depends on Phase 545 and should be stacked after PR #214. This issue may be implemented as docs/tests-only while earlier PRs wait for review, but it must not claim those earlier PRs have merged.
