Feature: TDD Issue #570 — session create DI container missing db provider
  As a developer
  I want to verify that `agents session create` fails due to the
  DI container missing a `db` provider
  So that the bug is captured and will be caught by a regression test

  The root cause is shared with bug #554: `_get_session_service()` in
  session.py calls `container.db()`, but the Container class has no `db`
  provider, causing an AttributeError at runtime.

  Scenario: Session create command succeeds via DI container
    Given a CLI runner using the real session DI path
    When I invoke the session create command
    Then the session create command should exit successfully

  Scenario: Session create with actor succeeds via DI container
    Given a CLI runner using the real session DI path
    When I invoke the session create command with actor "openai/gpt-4"
     Then the session create command should exit successfully

  Scenario: Session create command produces structured output via DI
    Given a CLI runner using the real session DI path
    When I invoke session create with actor "local/orchestrator" and format "json"
    Then the session create command should exit successfully
    And the session create JSON response should match the session create spec
