* feat: add mobile library targets for iOS and Android
- three library-mode-only triples join SCRIPTC_TARGET:
aarch64-apple-ios, aarch64-apple-ios-simulator (darwin hosts with
Xcode's iPhoneOS/iPhoneSimulator SDKs), and aarch64-linux-android
(any host with an NDK). The consuming pattern is an embedding app
linking profile-configured static archives — Xcode on the Apple side,
Gradle/NDK on the Android side — so the executable lane refuses the
triples with SC3002 and the pointer to --lib
- zig bundles no Apple or bionic libc: resolveCc discovers the sysroot
(xcrun for the selected Apple SDK; ANDROID_NDK_ROOT or the newest
ndk/<version> under the SDK root) and spells it into targetArgs,
where every cache tier already keys it. The canonical LLVM spellings
map to zig's own with the minimum-version floors pinned:
aarch64-ios.15.0[-simulator] stamps LC_BUILD_VERSION minos 15.0 into
every object, aarch64-linux-android.26 pins the bionic stub level an
embedder's minSdkVersion must meet. API 26 bionic carries everything
the library-lane units call (arc4random_buf included), so no shim TU
joins the archive
- localization follows the existing object-format rule: both iOS
platforms ride the Mach-O host-ld64 arm (ld64 reads iOS objects and
preserves platform/minos through the -r merge), Android rides the
cross-ELF arm (zig relocatable merge + in-process demotion) via the
driver's zig spelling. abi.instance_per_thread needed no per-target
work — thread-local statics compile identically on all three
- admission is a pure env/host check ahead of toolchain discovery: an
iOS triple off a darwin host and near-miss mobile spellings refuse
SC3002 with the pairing or the supported set named, in compile() and
compileLibrary() both, decorated by the profile teaching machinery
- library-multi grows the mobile lanes: M12 admission shape always
runs; SCRIPTC_IOS=1 builds localized a/b archives per target and
emission (M1 symbol exactness, ambient audit, version floor), links
probes with the Xcode clang, and EXECUTES the two-instance and
four-thread probes on a booted simulator byte-for-byte against the
desktop expectations (device-arch archives are build+link verified);
SCRIPTC_ANDROID=1 does the same through the NDK clang and an
emulator, reusing a running device or writing and booting a headless
arm64 AVD directly
- the surface manifest's coverage notes record the mobile posture (the
library-admissible surface only; no mobile claim outside it), the
profile spec and the platforms page carry the mobile matrix with the
version floors, and non-mobile builds are unchanged byte-for-byte

- Verify the workspace build plus plain and sanitized full test lanes.
- The CA-store surfaces (tlsca.get/root/set) demote the determinism attestation but no fence could deny them: three AMBIENT_SURFACE_FNS rows, one per Node spelling. Split rather than folded into a single "CA store" surface — an author who denies REPLACING the trust anchors is making a different decision from one who denies reading them, and rootCertificates is a value read with no call form to hang a table row on.
- The parity test's full-fence declaration set names the new node-builtin.tls. family; surface-manifest.json regenerated.
- Order-parity baselines for the seven fixtures the two lanes added (2556-2558, 2582-2585). Pure insertions: no recorded baseline moved.
- The crypto introspection statics (getFips and the cipher/hash/curve name lists) bake at the call site, and the crypto constant table joins http2's under a generalized per-module baked-constants lowering.
- The CA-store introspection surface lands in its own unit (scr_tls_ca.c) behind its own link gate, so a getCACertificates-only binary never pulls mbedTLS: getCACertificates, rootCertificates, setDefaultCACertificates.
- http2.createSecureServer grows the eager request handler and the runtime options record, riding the same server-options walk as tls.createServer; string-typed 'data' listeners decode.
- process once/off for 'unhandledRejection' plus the sibling 'rejectionHandled' registry, removal by closure identity per the warning-registry stance.
- Merge resolution unions this lane with main's fs ladders, createRequire erasure, and dyn secure-context work; the runtime's retired "DOM" nickname is spelled "dyn" throughout.
- Node serves the builtin for both spellings — a builtin wins over a same-named npm package for the bare specifier — so both key the same lowering tables
- The stale prefix-only caution predated the createRequire erasure; the hint's claim and the behavior now agree
- text, json, and buffer settle real promises over the readable machinery with Node's settle timing and rejection set; arrayBuffer and blob fence with their representation reasons
- createRequire over this file's URL is compile-time plumbing: builtin specs become namespace imports, relative JSON bakes as validated documents, npm packages ride the require-condition graph, unresolvable names throw Node's catchable MODULE_NOT_FOUND
- module.builtinModules bakes as the compat target's exact list
