Keep ENV metadata at section 15 and move draft capabilities to section 16. Regenerate module-library definitions together and preserve explicit host authority through canonical procedure namespace resolution.
Keep ENV imports at Wasm10.6 and JS2.2 and move invocation authority to Wasm10.7 and JS2.3. Preserve Environment15 and Capabilities16. Carry the reviewed sealed Rust ENV trait, module-library fixes, and CLI extraction/output changes. Preserve .NET10 NativeAOT linkage for the authorization import alongside ENV. Validated all five actual ENV cases, actual Wasm and V8 authority checks, four module libraries, Rust compile diagnostics, and scoped lint.

Description of Changes
Carries host-verified invocation authority into Wasm and JavaScript modules, independently of sender Identity, connection IDs, or JWT presence. Updates all four module libraries to preserve authentication through procedure transactions and use the verified sender for JWT identity. Adds the
hosted_auth_v1capability marker.The Container Hosting prerequisite is limited to authentication. Explicit visibility declarations, scheduled overrides, migration diagnostics, and lifecycle code-generation changes are deferred to #5958. Private companion: #3941. No website changes are required.
API and ABI breaking changes
Adds a V10 capability section and host imports without changing existing tags or visibility defaults. Newly compiled modules require an updated host. No V11 ABI.
Rollback safety impact
Based on merged ENV #5887. Older hosts cannot load modules using the new capability section or imports; restore compatible module builds before rolling back the host.
Expected complexity level and risk
3/5. Changes module-visible authentication and its compatibility boundary; existing lifecycle admission remains restricted.
Testing
Rust core, module-library, CLI and integration-test targets compile. 143 schema tests, 22 library tests, the real V8 invocation-authority test, and nine TypeScript authentication/ENV tests pass. Full TypeScript checking is locally blocked by missing solid-js; C# execution requires the repository's .NET 10 SDK. CI reruns on the reduced diff.
