EditContext

Type: platform primitive reference

EditContext is the future-facing platform primitive in this lane.

Why it matters

• makes IME text updates, selection updates, layout updates, and text-format feedback explicit
• proves IME-owned formatting is its own lane, not just another decoration hack

Strongest local evidence

• ../edit-context/dev-design.md

Limits

• not mature enough to be today’s foundation
• track it aggressively, but do not bet the current runtime on it
