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.
