Parse the vendored schema with serde_json::Value and serialize compact JSON
in build.rs. Embed the generated bytes without request-time processing.
Verify the embedded protocol matches the complete vendored schema.
Validation on the unchanged final source tree: cargo fmt --all;
cargo clippy --workspace --all-targets --all-features -- -D warnings;
cargo nextest run --no-fail-fast (20,505 passed, 18 existing skips).
Expose protocol-independent InstanceCommand and BrowserInstanceControl with a
native serve_with_control entry. Keep shutdown coordination in the server and
CDP session validation and response flush in a dedicated adapter, bypassing
renderer work without creating another actor or shutdown state.
Parse each CDP envelope once and check live frontend-owned session routes
through a weak registry view. Match Chromium Browser.close on browser, page,
tab, and worker sessions; ignore params and reject null or foreign session IDs.
Update optional-session test requests to omit absent routes.
Add native and pending-promise lifecycle regressions and cross-engine smoke
coverage for acknowledgment ordering, natural process exit, and isolation.
