Results:
- agent-node unit test: 35 pass, 0 fail, 75 expect calls.
- server unit tests: 31 pass, 0 fail, 76 expect calls.
- Docker qa-rfc026-create-node: failed on current main-adjacent suite expectations before any model-optional-specific failure:
  - Suite 1 reported PASS=58 FAIL=1 SKIP=1; failure was cross-network rejection expecting the old error shape while hub returned access_denied.
  - Suite 2 failed daemon startup with alias_identity_mismatch after login-state convergence.
