- README stays the source of truth for current state; drive/item-5 now
reflects the settled decision: String IDs for the MVP, slotmap deferred.
- ROADMAP gains a 'point de depart' (present-state) block, marks glam done,
removes the slotmap Phase-1 mandates, and documents the String-ID decision
plus the deferred 'typed handles' step.
- PLAN corrects stale [X] checkmarks (App render() cannot draw, Scene
rendering not automated, simple example does not compile) and notes its
verification checklist against current reality.
- Remove the unused slotmap direct dependency from wsg-lib (package remains
in Cargo.lock only as a transitive dep of glow).
