- Compile production program loading across module graphs, packages, and configuration
- Preserve optional defaults and support runtime URL bases and regex split captures
- Isolate host execution services and initialize lowering tables outside module cycles
Lower static and non-overridden instance generator methods through spawn wrappers. Bind sync and async generator loop values through declarations or assignment patterns, and preserve compound assignment expression values.
* Warn on non-null assertions
- Surface non-null assertions during linting without making them blocking.
- Preserve existing assertion sites for opportunistic cleanup.
* Classify internal compiler errors
- Export InternalCompilerError and migrate compiler invariant throws without changing messages.
- Rename the native cache test to match cc.ts and update test scheduling references.
- Document test placement by unit, package integration, and cross-package scope.
* Fix internal compiler error classification
* Reuse IR across comment-only library edits
- Restore validated lowered IR when TypeScript edits change only non-semantic comments
- Rebase source locations and regenerate exact-source sidecar and build identities
- Add semantic invalidation, integrity, and real-cache coverage
* Fix semantic cache lexical validation
* Use canonical IR version in semantic cache
* Fix semantic cache lexical rebasing
* Fix semantic cache Unicode identifiers
- the fs shadow serves opted-in bundle files with the plumbing space-padded and one canonical tail table: chased getter values as alias-plumbed entries, star re-exports as spreads plus per-name member reads, lexer-visible-but-unchaseable names as checked-dynamic any bindings valued undefined
- lexer parity is the contract: the rewritten text answers the same name set to the CJS lexer that the original answers Node, unused helper declarations sweep away, and esbuild's __esModule marker is deliberately omitted (Node never lexed it; spelling it flips default-import interop)
- npmStaticPackageOfPath answers for opted-in workspace realpaths, and the shadow registers a symlinked install's realpath the moment resolution touches it (nested-realm monorepo drivers)
- non-opted UNTYPED node_modules packages serve as an any-surface stub so maxNodeModuleJsDepth cannot change the program's own types under the flag
- auto eligibility refuses only bundler-runtime markers (__webpack_require__) now that degradation is graceful
