Problem

Follow-ups decided with the maintainer on 2026-11-03 had no quests:

• Rust types should get a runtime wrapper where a JS native type can't hold std's semantics ("trying to support native types is probably a mistake", on feat(ts): a Vec as rt.Vec, holding std's exact capacity #555), with an aliased or branded native type kept where it holds them all with no extra allocation.
• The runtime's namespace should be rs, not rt.
• Two Python per-call costs measured in perf(ffi): hold a Python call's handles inline #560 and perf(ffi): resume a Python wake on the loop's own thread without the socket pair #564.

Approach

• ts-rs-rename [S]: rename rt to rs, as its own PR.
• ts-string-capacity becomes rs.String [L]: String, Box<str> and &str as a runtime type holding std's capacity. Measure a JS-string-backed and a UTF-8-backed wrapper and bring the numbers back as a decision.
• ts-slice-object becomes rs.Slice [L]: slices and arrays of other values as array, start and length. It absorbs ts-slice-of-one, and both waits are dropped.
• ffi-python-methods [M]: native methods on generated classes, about 25 ns per call. The GIL release is kept.
• ffi-python-loop-lookup [S]: skip perf(ffi): resume a Python wake on the loop's own thread without the socket pair #564's running-loop lookup unless something waits, about 14 ns per in-loop call.

Primitives, Option, tuples and closures stay native. The wrapper quests run in parallel with the rename.

Impact

• None: quests only.

Alternatives

• Wrap every type, primitives included: rejected, since it costs an allocation per number for no semantics gained.

Follow-ups

• None.
