Scope-B milestone NI-1, API side: the explicit call API that replaces the
build container's hand-written node subprocess (api patch 09).
- The new package @scriptc/node exports callSync(specifier, name, ...args)
and call(...). The module loads with require() from the calling module;
arguments and results cross as JSON copies; a thrown Error crosses as its
nearest intrinsic class with its message and string code, other thrown
values as JSON copies; callSync refuses a function that returns a
promise. Its Node implementation runs the calls in-process with the same
copies, so a program prints the same under Node and compiled.
- The compiler lowers calls to the named or namespace imports
(node-api-import.ts, lower-node-island.ts) to the nodeIsland.callSync
and nodeIsland.call libCalls: the calling module's real path, the
specifier, the export name and the boxed argument array, with the result
checked against the declared type like `JSON.parse(s) as T`. Arguments
and results whose types are not JSON data are refused at build time, and
the functions and the namespace refuse as values.
- Corpus programs 6800-6803 (sync and async results, errors, process.exit
from Node with the program's exit listeners, Node's pending timers
keeping the program alive) run under Node and as binaries that load
libnode; `// @requires-libnode` skips them where SCRIPTC_LIBNODE names no
pack (until the pack CI matrix publishes packs). The node-island harness
covers loading Node only on the first call, the beside packaging, a
missing pack, a pack of another Node version or bridge ABI, and the
executable's symbols.
- Release tooling publishes @scriptc/node with the other packages.

T10 and T12 of the zero-cost compatibility plan, plus the maintainer
decisions:
- Programs that name Temporal type-check against TS 7's temporal lib
(added only for them) and lower to Node 24's answers: typeof is
"undefined", globalThis.Temporal is undefined, other uses throw
ReferenceError at the root read.
- node:v8 is importable; getHeapStatistics answers allocator-derived
figures in Node's shape; other members fence with the by-design reason.
vm's refusal says why.
- node:stream/web exports the web stream globals themselves.
- node:dns/promises and dns.promises: lookup and lookupService as
promises, in the link-gated scr_dns_promises.c unit.
- eval and the Function constructor throw Node's EvalError under
--disallow-code-generation-from-strings; the corpus harness runs the
Node oracle with that flag for `// @disallow-code-generation`.
- graceful-fs is served as node:fs.
Every new lowering replaces a refusal, and the new runtime code links only
when used, so other programs compile to identical bytes (zero-cost gate).

exec(command, callback) and exec(command, { encoding, maxBuffer },
callback) lower like execFile's callback slice. The command line runs
with /bin/sh -c, as execSync runs it, the call returns the live
ChildProcess, and the error-first callback receives the captured utf8
stdout and stderr. A non-zero exit, including the shell's 127 for a
missing command, reports Node's "Command failed: <command>\n<stderr>":
scr_exec_file takes a shell flag so the message shows the command line.
Under @types/node, child_process.ExecException maps to Error, as
ExecFileException does. Its code member is the child's numeric exit
status, which the runtime error's string code slot does not hold, so
reading it, testing it with `in`, or testing its typeof is a named
refusal.

A const binding of promisify(exec) now lowers like promisify(execFile):
each call runs the command line with /bin/sh -c, as execSync does, and
settles with { stdout, stderr }. A non-zero exit, a missing command (the
shell's 127) or a timeout rejects with Node's "Command failed: <command>\n
<stderr>" message. The options are the execFile slice: encoding utf8,
cwd, env (inline spread included), timeout, and maxBuffer accepted.
Three gaps closed for both targets along the way:
- the { stdout, stderr } result maps as a record when it is held in a
variable, passed or returned, instead of only when destructured at the
await (it is an anonymous literal in @types/node and in the fallback);
- a namespace member is a recognized target (promisify(cp.exec));
- util.promisify(...) through a namespace or default import is
recognized like the named import.
- Enforce oxlint and oxfmt for owned JavaScript and TypeScript with independent CI checks.
- Preserve compiler import boundaries and protected fixtures while cleaning up lint findings.
- Standardize source formatting and validate import, fixture, and embedded-source protections.
- 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.
- Preserve fields, accessors, added properties, and cyclic references across untyped class boundaries.
- Support platform signal names and native exception handlers that resume queued work.
- Configure attached Windows consoles for UTF-8 while preserving redirected bytes and restoring host state.
- Add cross-platform output coverage and a native pseudo-console regression.

- library-mode, library-contract (cache dir plus the tmpdir npm root), and library-asyncfree now carry a plain/san path segment: both flavors run the same ordinary builds, and the nightly's concurrent both-flavor recipe raced ar/ranlib in the shared dirs ("can't open file ... lib.lib.a"); the per-build -san tag stays, it distinguishes explicitly-sanitized builds within one suite
- the same flavor split lands on npm-static's fixed npm-static-workspace dir (the two flavors even build with different sanitize flags there), provenance's shared outDir, and diagnostics' $TMPDIR/scriptc-diag scratch (some entries emit backend artifacts before failing)
- dec-oracle publishes in the differential/llvm/linux/windows lanes are now atomic (write tmp, rename): the content-keyed path is shared across flavors and lanes, and a truncate-and-rewrite could expose a torn oracle to a concurrent reader
- every other suite already keys its build dirs by a content hash that includes the flavor, and the CAS build cache folds the sanitized flags into its key, so those stay as they are
- proof: three consecutive concurrent both-flavor library-mode runs from a wiped cache all pass 45/45 with zero ar/ranlib failures, and a concurrent both-flavor run of all four library suites passes 125/125 in each flavor
- buf.compare / buf.equals / Buffer.compare arguments that are not statically bytes route through checked-dynamic validators (buffer.compareChk / bytes.equalsChk / bytes.compareChk) running Node's own ladders: ERR_INVALID_ARG_TYPE with the API's argument names and determineSpecificType renders, validateOffset's ERR_OUT_OF_RANGE, undefined slots taking Node defaults — and well-typed dyn values still compute real answers.
- The bytes range ladders (validateOffset, boundsError, checkInt, swap, fill, randomBytes, fs.readSync) stamp their Node codes (ERR_OUT_OF_RANGE / ERR_BUFFER_OUT_OF_BOUNDS / ERR_INVALID_BUFFER_SIZE / ERR_INVALID_ARG_VALUE); validateOffset renders ±Infinity as 'an integer' like Number.isInteger.
- The deprecated `new Buffer(number, enc)` string arm throws Node's ERR_INVALID_ARG_TYPE (the throwing path fires no DEP0005, so compiled silence matches); other ctor forms keep their fences.
- assert.throws/rejects accepts a plain expected object held in a variable (the shared `{ code: ... }` expectation record) through the errValue key walk.
- scr_dyn_specific_type/scr_dyn_arg_type_fail move beside the DOM core (scr_json.c) so always-linked validators render through them; the handle unit keeps the listener gate.
- The differential lanes learn `// @no-deprecation` (Node oracle runs --no-deprecation) for fixtures pinning deprecated-API error paths; corpus 2556 pins the whole ladder byte-identically on both backends.
