Compile the shared Rust CLI for wasm32-wasip1-threads and supply filesystem,
network, process, terminal and cancellation capabilities through a Node host.
Select host implementations at compile time so native builds retain their
native dependency/features and execution paths.
Bundle the WASM runtime in the regular npm wrappers and select it from the
WebContainer runtime marker. Keep Node launchers usable without installation
scripts. Native installation replaces all four launchers with native bytes.
Regenerate shims after upgrades or dependency builds replace Node targets with
native binaries, including before dependent lifecycle scripts run. Preserve
collision winners and publish replacement shims with executable permissions.
Reject non-descendant permission templates and intermediate symlink escapes, validate before creating directories, and avoid path-based cleanup races.
Restore direct native aliases in both version-management implementations.
Retain process cleanup after failed stdin shutdown. Prevent cross-origin redirects from replaying login credentials in both CLI lines, and strip npm-otp from cross-origin WASM requests. Avoid repeated selected-snapshot and removed-bin scans.
Preserve resolution, lockfile, integrity and build-approval behavior. Use an
isolated WASM store with rollback journals and process leases. Patch WASI path
normalization for multiple parent segments and retain that patch in bundles.
Add pinned tooling, release packaging, real-browser workflow and selection
tests, documentation and a release note. Document host limits, including the
Corepack cold-download failure in WebContainer's streaming hash implementation.
Controlled native CLI cases showed no separated slowdown, and the latest
hoisted rebuild and repeat-install fixture improved. Retain the documented
microbenchmark uncertainty and host limitations.
