- Infer safe input lifetimes across checked reads, calls, conversions, and comparisons.
- Reuse immutable primitive values during construction and JSON parsing.
- Preserve callback ordering, result ownership, and exception cleanup.
- Preserve fresh constructor identity and shared captures across local class instances.
- Carry constructors through unknown values without a JavaScript engine.
- Support runtime-length spreads into fixed and rest parameters.
- Run production scope and closure capture logic with native TypeScript 7 symbols.
- Give lowering caches explicit pass ownership and stable symbol identities.
- Support reference collection arrays and optional Set seeds on both native backends.
- Share program creation, checker queries, virtual files, and snapshot lifetimes between Node and native compiler clients.
- Preserve typed async-context results and opaque compiler objects through checked native boundaries.
- Support native realpath and Unicode Windows filesystem operations needed by the compiler host.
- Compile production IR serialization and runtime dependency scans on both native backends
- Support native JSON callbacks and checked records with unknown payloads
- Verify native IR round trips and executable generation with focused sanitizer coverage
- The ratified rename rider (world-unification §7 lane 5): "DOM" collided with the browser DOM and, post-lane-1, the structure is no longer a document tree. Comments and doc prose now say "the checked-dynamic tree" for the noun and "dyn" adjectivally; runtime symbol names (scr_dyn_*), the error.domClone libCall, and the real web DOMException family are unchanged.
- The few user-facing strings carrying the nickname move with it (the structuredClone cyclic message, the dc subscriber/publish fences, two emitter ICE texts); diagnostics snapshots regenerated (96 pass). One private compiler constant (DOM_PROTO_METHOD_NAMES -> DYN_PROTO_METHOD_NAMES) rides along.
- Mechanical sweep, 142 files, comments/prose only — no behavior change.
