It is not a user-supplied MCP server. +3. **`gh-aw-mcpg` (trusted policy gateway).** The primary agent can reach the + enclave server only through `gh-aw-mcpg`.

Trusted configuration declares a shared set of private repositories, +their sensitivities, and two executor kinds: + +- **script** runs a fixed interpreter in a no-network sandbox; +- **agent** runs a fixed native agent on an API-proxy-only network. + +Runtime, image, model, network, timeout, resource, mount, credential, and tool +settings are trusted AWF configuration.

Staging credentials + exist only here. +2. **Enclave MCP server (trusted, AWF-owned).** AWF owns and launches the server. + It loads trusted executor configuration and the single repository ledger, + admits finite-schema requests, launches isolated executors, canonicalizes one + finite result, and protects audit state. It is not a user-supplied MCP server. +3. **`gh-aw-mcpg` (trusted policy gateway).** The primary agent can reach the + enclave server only through `gh-aw-mcpg`. The gateway guards the tool surface + and calls the AWF-owned server; it does not receive repository seeds, + credentials, executor configuration, or ledger state. +4. **Executor enclave (untrusted workload).** Each invocation receives only its + selected immutable seed and bounded input.

Add authenticated local + transport and readiness proof; do not expose direct broker ingress. +3. **`gh-aw-mcpg` integration.** Register and guard the AWF-owned server, wire + startup retry/timeouts, require end-to-end readiness before primary-agent + startup, and route both executor tools exclusively through the gateway. +4. **Runtime cutover.** Move staging, auditing, timing, and the shared ledger to + the unified server.
