The frontend calls tokenStartOfNode, getTextOfNode, getSourceFileOfNode and
forEachChild instead of AstNode's position and traversal methods. Node lists
answer hasTrailingComma(), and a declaration's modifiers are a modifier list
with their flags.
Symbol, Type, Signature, IndexInfo, TypePredicate, Program, TypeChecker and
Diagnostic have tsc-ts/api's members and types. Compiler code reads symbol
names with symbolName(symbol).
tsc-ts goes to 0.0.5. api-conformance.ts asserts that AstNode, AstNodeList,
SourceFile and each node interface are assignable to tsc-ts/api's interface of
the same name, and names the members where the wire format differs.
package-shims.ts registers implementation modules shipped with the
compiler per package and major version (chosen by the importer's
installed version) and reads the project's never-loaded packages from
"scriptc": { "packages": { "<name>": "unloaded" } }. Module edges go
through resolveProjectImport; the npm resolution, the npm-edge walk and
the --npm-static set skip such packages; the tsgo host reads a shimmed
package's index.d.ts as a re-export of its implementation; an unloaded
package's require() throws Node's not-installed MODULE_NOT_FOUND.

scriptc's frontend talks to a TypeScript 7 API server. tsc-ts serves the
same API as tsgo, and it is now the default checker; SCRIPTC_CHECKER=tsgo
selects tsgo, which scriptc still includes.
- @scriptc/compiler depends on tsc-ts 0.0.3. The native distribution
ships its platform package as lib/tsc-ts, named by a new tsc_ts field
of the toolchain manifest; a manifest without it takes the executable
of an installed tsc-ts package.
- The executable cache key includes the tsc-ts executable's identity, in
the compiler and in the CLI's startup route.
- tsc-ts keeps the syntax trees it builds for the life of its process,
so the source parser starts a new server after 256 KB of parsed
source instead of letting one server grow with every file.
- A CI job compiles every corpus program with both checkers, in release
and dev, and requires the same LLVM IR and diagnostics
(scripts/checker-identity.mjs).
- Tests that compare with the TypeScript 7 SDK, the checker-panic
diagnostics, and the protocol tests run against tsgo.
- Synchronize published packages and the compiler surface manifest at v0.2.8, and bump the runtime ABI marker to v9.
- Add release notes for worker graph sharing, catchable deep recursion, parallel code generation, runtime performance, and compatibility fixes.
- Synchronize all published packages and the compiler surface manifest at v0.2.7.
- Record native features, runtime performance improvements, and compatibility fixes since v0.2.6; leave Unreleased empty.
- Verify version and manifest contracts, compatibility output, and cross-target library conformance locally; use CI for full validation.
- Release native workers, shared memory, and broader language and library support.
- Include runtime and compiler improvements in the release notes.
- Synchronize all published packages and the surface manifest at 0.2.6.
- Bump all published packages to 0.2.4.
- Document collection, performance, and Windows toolchain updates.
- Regenerate the versioned compiler surface manifest.
- Synchronize published compiler, runtime, and native platform packages at 0.2.0.
- Document the native CLI, LLVM migration, and compatibility and performance improvements.
- Keep release version checks scoped to published packages.
* feat: ship the self-hosted native scriptc CLI

- Install native platform packages and ship relocatable standalone distributions.
- Preserve program semantics and reuse validated build artifacts for fast rebuilds.
* fix: complete native CLI integration and validation
- Preserve library diagnostics and run recursive compiler work on the main stack.
- Restore packaged helper permissions and exercise native npm and Wasm library builds.
- Recover interrupted Sandbox status probes within the original command deadline.
- Remove C emission, debugging options, and automatic backend fallback.
- Complete LLVM lowering and native bootstrap coverage across supported targets.
- Link executables and libraries with precompiled C runtime packs, including iOS and Android.
- Align all published package versions and the surface manifest at 0.1.6.
- Record the static Array, Object, and String updates in the changelog.
- Summarize the runtime memory and terminal performance improvements.
- Bump published packages and the surface manifest to 0.1.5.
- Summarize the HTTP, numeric, and npm-static updates in the changelog.

* chore(release): prepare v0.1.4
- Bump the CLI, compiler, runtime, and platform packages to 0.1.4.
- Add v0.1.4 release notes and regenerate the static surface manifest.
* test: keep upgrade fairness client open through timer check
- Keep upgraded clients connected through the fairness timer check under CI load.
- Fail the driver clearly if its watchdog expires.
* test: record fork dispatch TS7 baseline
- Record the new fork dispatch corpus entry in the TS7 order canary.
- Pin its single-module evaluation order and empty preflight diagnostics.
* fix(runtime): complete fork IPC shutdown before close
- Release the IPC writer listener when the remote channel closes after writes finish.
- Deliver disconnect before close for forked children with active IPC listeners.
- Sync the CLI, compiler, runtime, and platform package version spine.
- Regenerate the compiler surface manifest for v0.1.2.

* Expand LLVM native output targets
- Add owned helper and runtime-pack contracts for macOS x64, Linux glibc/musl, Windows x64, and WASI.
- Generalize LLVM target selection, package validation, linker plans, and release/CI matrices.
- Document linker boundaries and add focused native-output and runtime-pack coverage.
* Pin Windows LLVM helper CI to VS 2022
The official LLVM archive needs the Visual Studio 2022 CMake generator, which is not guaranteed by windows-latest.
* Align bootstrap cache with LLVM runtime-pack builds
Use the same target-specific helper and linker identity before and after compiler loading so routed executable cache hits remain lightweight.
* Install Windows LLVM CI tools with Chocolatey
windows-2022 includes Visual Studio but not winget; use its available Chocolatey bootstrap for CMake and Ninja.
* Prevent Zig version probes from leaving runtime-pack objects
Run runtime-pack compiler version probes in a private temporary directory and remove the accidental tracked WASI a.o file.
* Use 7-Zip for Windows LLVM setup
Extract the official LLVM development archive with two-stage 7-Zip instead of Windows tar.exe, which timed out while materializing the toolchain tree.
* Define ssize_t for the MSVC runtime pack
Clang's MSVC target does not expose POSIX ssize_t through sys/types.h; define the pointer-sized runtime type without affecting MinGW.
* Build the Windows runtime pack with Zig
Use the MinGW-compatible Windows sysroot required by the runtime while retaining COFF helper output and installing Zig in the Windows native CI lane.
* Give macOS LLVM differential shard time to finish
Shard 1 passed its setup and focused contracts but was cancelled during its cold LLVM differential slice at the 20-minute job limit.
