BSD script takes the command after the transcript file, needs a stdin
that is not a socket, and echoes the EOF it forwards from /dev/null.

A nested entry below the mark makes its context with ni_make_context,
so macOS clears only the top slice of the range instead of the whole of
Node's stack below the mark on every nested call (17 ms per call, and
the cross-heap GC test ran past its timeout).

The libnode-linux action becomes .github/actions/libnode, which serves
the Linux x64 and macOS lanes: the libnode-packs cache for the runner's
platform, else the development pack.

macOS binds libnode's own calls to v8::base::Stack inside libnode, so the
bridge's definitions cannot give V8 Node's stack as they do on Linux; V8
took the main thread's stack start and its conservative scan faulted in
the gap above Node's stack. While Node starts on its stack, the main
thread's pthread record now names that stack, which V8 reads once and
keeps.
macOS's makecontext clears the whole stack it is given, so it gets only
the top slice of Node's stack (no 64 MiB pass per context).
CI: dev-pack.json pins mirrored darwin-arm64 and darwin-x64 libnode
builds of the pinned Node 24.22.0 from the libnode-packs workflow, the
dev-pack action serves either platform, and the macOS lanes provision it,
so island tests fail rather than skip on macOS CI. The arm64 LLVM job
runs the island harness; the Intel job runs it and the island corpus.
bridge-smoke loads the .dylib bridge on macOS.

The native bootstrap's package checks copy the seed's distribution into a
package directory outside the workspace and, since the CLI packages depend
on their LLVM helper and runtime pack, drop the bundled copies. Nothing in
that directory resolved @scriptc/llvm-linux-x64-gnu, so
verify-native-cli.mjs failed with 'Cannot find module'. The test now links
both packages into the directory's node_modules, as pnpm links a workspace
package's dependencies.
The teardown of a type with children of its own type called itself for
each child: a call, its register saves and the segment bookkeeping per
node, 45 instructions per node in a binary tree.
A record or standalone class whose every reference field holds its own
type and that has no collector header now tears down in one loop. A child
whose last reference the dead node held goes onto a pending list linked
through its own count word, which it no longer needs, and the loop takes
the list's first node next, so nodes are visited parent first. Each node
frees its block as before (dispose observers, the RC audit, blocks of
other arenas), the calling thread's blocks go into the teardown segment
in visit order, and the segment goes onto the free list in one step, so a
structure built parent first takes the blocks in its allocation order.
Shared and immortal children keep their release. The loop needs no depth
budget. Other teardowns keep the recursive form.
forEach, map, filter, some, every, find, findIndex, findLast,
findLastIndex and flatMap on a dynamic array, and through
Array.prototype.<method>.call on a native array, called the callback
without its thisArg, so `this` in the callback was not the second
argument. These methods now bind `this` to the thisArg, or undefined
when there is none, once per call, around all of the method's callbacks.
Each @scriptc/cli-<platform> package bundled its platform's LLVM helper
and runtime pack, which are also published as @scriptc/llvm-<platform> and
@scriptc/runtime-<platform>. The CLI packages now depend on those packages
at the same version (workspace:*, which pnpm pack writes as the exact
version) and leave them out: cli-linux-x64-gnu goes from 115 MB to 60 MB
packed.
- build-native-cli.mts --platform-packages, which each CLI package's
build:native passes, writes a manifest without llvm_package, runtime_pack
and runtime_packs.
- loadNativeToolchain resolves a missing helper or host runtime pack as
Node resolves the package from the compiler's directory: nested in the
platform package, beside it (hoisted, or pnpm's virtual store) or higher
up. It requires the compiler's version, and an absent or mismatched
package fails with an error that names it.
- installNativeCli records where the package manager put both packages in
the installed manifest, with the same checks.
- verify-native-cli.mjs requires the exact dependencies of a platform
package and checks the resolved packages' versions.
- package-native-cli.mjs bundles the helper and runtime pack into the
standalone archives, which stay self-contained.
- smoke-native-install.mjs installs the helper and runtime pack tarballs
with the platform package; the bootstrap's exported package drops its
bundled copies first.
- release.yml publishes the CLI packages only once every helper and
runtime pack package resolves on npm, and scriptc only once the CLI
packages resolve, each wait at most 25 minutes. A rerun skips the
uploads npm already accepted and waits again.
