Feature: Resume model coverage boost
  As a developer
  I want full test coverage for the resume domain models
  So that the record_checkpoint error path and as_cli_dict method are verified

  # --- ResumeMetadata.record_checkpoint error path ---

  Scenario: Recording a checkpoint with negative step_index raises ValueError
    Given I have a ResumeMetadata instance with 5 total steps
    When I record a checkpoint with step_index -1
    Then a ValueError should be raised with message "Checkpoint step_index must be >= 0"

  # --- ResumeSummary.as_cli_dict base case ---

  Scenario: as_cli_dict returns base fields when no optional fields are set
    Given I have a ResumeSummary with no optional fields
    When I call as_cli_dict on the resume summary
    Then the cli dict should have key "plan_id"
    And the cli dict should have key "phase"
    And the cli dict should have key "processing_state"
    And the cli dict should have key "last_completed_step"
    And the cli dict should have key "next_step_index"
    And the cli dict should have key "total_steps"
    And the cli dict should lack key "decision_id"
    And the cli dict should lack key "last_checkpoint_id"
    And the cli dict should lack key "sandbox_ref"

  # --- ResumeSummary.as_cli_dict with decision_id ---

  Scenario: as_cli_dict includes decision_id when set
    Given I have a ResumeSummary with decision_id "DEC001"
    When I call as_cli_dict on the resume summary
    Then the cli dict value for "decision_id" should be "DEC001"

  # --- ResumeSummary.as_cli_dict with last_checkpoint_id ---

  Scenario: as_cli_dict includes last_checkpoint_id when set
    Given I have a ResumeSummary with last_checkpoint_id "01JCHKPT0000000000000CHKPT"
    When I call as_cli_dict on the resume summary
    Then the cli dict value for "last_checkpoint_id" should be "01JCHKPT0000000000000CHKPT"

  # --- ResumeSummary.as_cli_dict with sandbox_ref ---

  Scenario: as_cli_dict includes sandbox_ref when set
    Given I have a ResumeSummary with sandbox_ref "/tmp/sandbox-abc123"
    When I call as_cli_dict on the resume summary
    Then the cli dict value for "sandbox_ref" should be "/tmp/sandbox-abc123"

  # --- ResumeSummary.as_cli_dict with all optional fields ---

  Scenario: as_cli_dict includes all optional fields when all are set
    Given I have a ResumeSummary with all optional fields set
    When I call as_cli_dict on the resume summary
    Then the cli dict should have key "decision_id"
    And the cli dict should have key "last_checkpoint_id"
    And the cli dict should have key "sandbox_ref"
    And the cli dict should have exactly 9 keys

  # --- ResumeSummary.as_cli_dict verifies correct base values ---

  Scenario: as_cli_dict base field values match the model
    Given I have a ResumeSummary with plan_id "01JABCDE1234567890ABCDEFGH" and phase "execute" and state "processing" and last_step 2 and next_step 3 and total 5
    When I call as_cli_dict on the resume summary
    Then the cli dict value for "plan_id" should be "01JABCDE1234567890ABCDEFGH"
    And the cli dict value for "phase" should be "execute"
    And the cli dict value for "processing_state" should be "processing"
    And the cli dict integer for "last_completed_step" should be 2
    And the cli dict integer for "next_step_index" should be 3
    And the cli dict integer for "total_steps" should be 5
