- Move plain and shaped text line planning, trailing ellipsis, alignment, caret mapping, hit testing, and ink geometry into compiled TypeScript. Retain the independent native reference and explicit font measurement capabilities.
- Use caller-owned source facts and fixed-size copied continuations; preserve complete line state, numeric behavior, content identity, and frame-reset ownership.
- Add complete native parity tests, malformed transport coverage, long-text and font-callback cases. Focused Debug and ReleaseFast suites, portable bundle typechecking, and scriptc 0.2.4 CLI compilation pass.
… into compiled TypeScript. - Preserve native measurements, complete layout parity, and copied ABI ownership.
…final app link. - Complete paragraph transport fixtures and theme ownership expectations.
- Compile plain and shaped line, elision, caret, hit-test, and ink geometry decisions. - Preserve font capability ordering and copied caller-owned transport with complete native parity tests.

- Preserve app integer contracts while compiling text geometry across complete application graphs. - Keep planner transport, font capability ordering, and native parity unchanged.
- Share action and focusability results from one copied response. - Limit scroll observations to the queried widget while preserving full tree geometry.
- Reuse one per-call context for portable text planning. - Integrate shared semantic queries while retaining complete native parity.
- Reuse copied continuation state and avoid redundant scalar scans. - Preserve numeric behavior, font capability order, and native reference parity.
