…on mitigations - Move 49 domain tests from FIX-12 to UNSUPPORTED-MODULE - Fix Sign/Verify classifier matching non-crypto tests - Move unsupported-module/api category check before reason-based classifiers - Add 3 additional cross-validation mitigations (crypto test vectors, error snapshots, host-side assert) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…entries dgram (UDP) is planned for implementation, not out of scope. https, http2, tls, net, readline, diagnostics_channel, async_hooks are bridged/deferred modules incorrectly globbed as unsupported-module. ~822 of 1226 UNSUPPORTED-MODULE tests are actually fixable.

…bility Lists modules (cluster, worker_threads, vm, inspector, domain, repl, trace_events, wasi), APIs (fork, execPath, V8 flags, snapshots, native addons), and behaviors (OS signals, fs.watch, multi-context, QUIC) that cannot be supported due to sandbox architecture constraints, with explanations for each.

Explains the virtual kernel architecture: all I/O routes through VFS, network stack, process table, and permissions engine. Clarifies that HTTP server loopback routes through the kernel without real TCP, VFS is not the host filesystem, and embedders provide host adapters.

All I/O must route through the virtual kernel. Network loopback is kernel-mediated. VFS is not the host filesystem. New I/O features must go through the kernel, never bypass to host directly. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Covers virtual socket table, loopback routing, server sockets, UDP, Unix domain sockets, socket options, network permissions, signal handlers, VFS change notifications, and migration of 13 Node.js bridge components to the shared kernel. Includes standalone test strategy and migration order. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…ction - Detail WasmVM current state (TCP/TLS/DNS/poll exists but bypasses kernel) - Specify migration path: driver sockets → kernel socket table - Add new WASI extensions: net_bind, net_listen, net_accept, net_sendto, net_recvfrom - Specify C sysroot patches for bind/listen/accept/sendto/recvfrom - Detail kernel-worker.ts and driver.ts changes - Specify blocking semantics (Atomics.wait for accept/recv) - Specify cooperative signal delivery at syscall boundaries - Add WasmVM-specific test files and C test programs - Add proofing section: implementation review, conformance re-test, expectations update, and PRD update via Ralph Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Addresses all 8 use cases: - K-10: Unified blocking I/O wait system (WaitQueue/WaitHandle) - K-11: Inode layer (allocator, refcount, deferred unlink, hard links) - K-8 expanded: Full sigaction (SA_RESTART, sigprocmask, coalescing) - Socket API: add shutdown(), socketpair(), sendTo(), recvFrom(), poll() - Socket flags: MSG_PEEK, MSG_DONTWAIT, MSG_NOSIGNAL, O_NONBLOCK - Socket states: add read-closed/write-closed for half-close - HostSocket: add setOption(), shutdown() - Wildcard address matching, error semantics, datagram limits - Updated test file list and migration order Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
