### Correctness (Static — Structural Evidence)

| Requirement                                       | Status        | Notes                                                                                                                                                                                |
|---------------------------------------------------|---------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Explicit Code-Mode Entry                          | ✅ Implemented | CLI `code` command and explicit code profile config in `clients/agent-runtime/src/main.rs`.                                                                                          |
| Structured Code-Session Output Contract           | ✅ Implemented | `CodeSessionResult` structure + parsing/rendering in `clients/agent-runtime/src/agent/code_session.rs`; prompt enforces FINAL RESULT in `clients/agent-runtime/src/agent/prompt.rs`. |
| Delegated Code-Session Execution                  | ✅ Implemented | `delegate` Session mode launches `Agent::code_from_config_with_delegated` and returns structured result in `clients/agent-runtime/src/tools/delegate.rs`.                            |
| Security and Approval Parity                      | ✅ Implemented | Delegated sessions reuse `SecurityPolicy` and approval gates; parity tests in `clients/agent-runtime/src/security/policy.rs` and `clients/agent-runtime/src/approval/mod.rs`.        |
| Observability and Validation Reporting            | ✅ Implemented | Code-session event + audit fields in `clients/agent-runtime/src/observability/traits.rs` and `clients/agent-runtime/src/security/audit.rs`.                                          |
| Specialized Session Reuse (agent-loop delta)      | ✅ Implemented | `Agent::code_from_config_with_delegated` uses canonical bootstrap in `clients/agent-runtime/src/agent/agent.rs` and `clients/agent-runtime/src/bootstrap/mod.rs`.                    |
| Delegated Specialized Sessions (agent-loop delta) | ✅ Implemented | Session mode enforces budgets and structured result in `clients/agent-runtime/src/tools/delegate.rs`.                                                                                |

### Coherence (Design)

| Decision                                            | Followed? | Notes                                                                                                                                                      |
|-----------------------------------------------------|-----------|------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Reuse existing runtime stack for code mode          | ✅ Yes     | `Agent::code_from_config_with_delegated` + bootstrap reuse in `clients/agent-runtime/src/agent/agent.rs` and `clients/agent-runtime/src/bootstrap/mod.rs`. |
| Evolve `delegate` into session runner               | ✅ Yes     | Session branch in `clients/agent-runtime/src/tools/delegate.rs` uses canonical loop and structured output.                                                 |
| Model code-session behavior declaratively in config | ✅ Yes     | `CodeSessionConfig` + `DelegateExecutionMode` in `clients/agent-runtime/src/config/schema.rs`.                                                             |
| Keep security and approval semantics identical      | ✅ Yes     | Delegated parity tests + shared policy in `clients/agent-runtime/src/security/policy.rs` and `clients/agent-runtime/src/approval/mod.rs`.                  |
| File changes align with design                      | ✅ Yes     | New `clients/agent-runtime/src/agent/code_session.rs` plus updates to main, prompt, delegate, traits, observability, audit, policy, approval.              |

### Issues Found

**SUGGESTION** (nice to have):

- Add explicit integration test covering successful delegated session path with structured result.
