The placeholder listed three candidates to evaluate as by-design divergences:
v-if/null comment host nodes, reactivity-driven re-render timing, and keyed
reconciliation order. Grounding each in the runtime code shows all three produce
byte-identical terminal output vs Ink — a commit always paints f(current host
tree), so *how* the tree was built never reaches the terminal. None is a
divergence, so the placeholder is removed and the three are recorded as concise
one-liners under "Framework idioms (noted, not behavioral divergences)":
- v-if=false / null|false|undefined children become an inert Comment vnode
(TuiComment) — no yoga node, paints nothing, doesn't shift a sibling's yoga
index, skipped for the positional <Transform> index (G52); output equals
omitting the element.
- Commit timing is deliberately Ink-aligned (~32ms ceil(1000/maxFps) throttle,
sync resize), so Vue's fine-grained re-render granularity stays unobservable.
- Keyed lists use Vue core's patchKeyedChildren, not React's fiber diff; output
depends on the final tree, not the move order.
