- registry/components/auth_service_account: TinyGo impl for Google
Service Account (JWT-bearer → token exchange) and base structure
for AWS SigV4.
- .component-builds/auth_service_account: independent Worker at
auth-service-account.arcrun.dev, extends wasi-shim with an
http_request host function for the token exchange step.
- Delete cypher-executor/src/lib/wasm-executor.ts (legacy, replaced
by component-loader WASM HTTP runner path).
- credential-injector.ts service_account branch now throws — all
service_account recipes must route through auth-dispatcher.
Per .agents/specs/arcrun/credential-primitives-wasm Phase 2.
