Cleanup Stale With No Existing Branch Is Idempotent
    [Documentation]    cleanup_stale does nothing when no stale branch exists
    ${result}=    Run Process    ${PYTHON}    ${HELPER}    cleanup-stale-no-branch    cwd=${WORKSPACE}
    Log    ${result.stdout}
    Log    ${result.stderr}
    Should Be Equal As Integers    ${result.rc}    0
    Should Contain    ${result.stdout}    cleanup-stale-no-branch-ok

Cleanup Stale Removes Existing Branch
    [Documentation]    cleanup_stale removes a stale worktree branch
    ${result}=    Run Process    ${PYTHON}    ${HELPER}    cleanup-stale-removes-branch    cwd=${WORKSPACE}
    Log    ${result.stdout}
    Log    ${result.stderr}
    Should Be Equal As Integers    ${result.rc}    0
    Should Contain    ${result.stdout}    cleanup-stale-removes-branch-ok

Cleanup Stale With Empty Plan ID Is Safe
    [Documentation]    cleanup_stale handles empty plan_id without raising
    ${result}=    Run Process    ${PYTHON}    ${HELPER}    cleanup-stale-empty-plan-id    cwd=${WORKSPACE}
    Log    ${result.stdout}
    Log    ${result.stderr}
    Should Be Equal As Integers    ${result.rc}    0
    Should Contain    ${result.stdout}    cleanup-stale-empty-plan-id-ok

Diff Against Head Returns None When No Branch
    [Documentation]    diff_against_head returns None when no worktree branch exists
    ${result}=    Run Process    ${PYTHON}    ${HELPER}    diff-no-branch    cwd=${WORKSPACE}
    Log    ${result.stdout}
    Log    ${result.stderr}
    Should Be Equal As Integers    ${result.rc}    0
    Should Contain    ${result.stdout}    diff-no-branch-ok

Diff Against Head Returns Diff When Branch Has Changes
    [Documentation]    diff_against_head returns a non-empty diff when the branch has commits
    ${result}=    Run Process    ${PYTHON}    ${HELPER}    diff-with-changes    cwd=${WORKSPACE}
    Log    ${result.stdout}
    Log    ${result.stderr}
    Should Be Equal As Integers    ${result.rc}    0
    Should Contain    ${result.stdout}    diff-with-changes-ok

Diff Against Head With Empty Plan ID Returns None
    [Documentation]    diff_against_head returns None for empty plan_id
    ${result}=    Run Process    ${PYTHON}    ${HELPER}    diff-empty-plan-id    cwd=${WORKSPACE}
    Log    ${result.stdout}
    Log    ${result.stderr}
    Should Be Equal As Integers    ${result.rc}    0
    Should Contain    ${result.stdout}    diff-empty-plan-id-ok

Strategy Actor Resolves To None For Stub Config
    [Documentation]    resolve_strategy_actor returns None when config_value is "stub"
    ${result}=    Run Process    ${PYTHON}    ${HELPER}    strategy-actor-stub    cwd=${WORKSPACE}
    Log    ${result.stdout}
    Log    ${result.stderr}
    Should Be Equal As Integers    ${result.rc}    0
    Should Contain    ${result.stdout}    strategy-actor-stub-ok

Strategy Actor Resolves To None Without Registry
    [Documentation]    resolve_strategy_actor returns None when no registry is provided
    ${result}=    Run Process    ${PYTHON}    ${HELPER}    strategy-actor-no-registry    cwd=${WORKSPACE}
    Log    ${result.stdout}
    Log    ${result.stderr}
    Should Be Equal As Integers    ${result.rc}    0
    Should Contain    ${result.stdout}    strategy-actor-no-registry-ok

Correction Diff Returns Output For Plan Without Changeset
    [Documentation]    correction_diff returns a message when no changeset exists
    ${result}=    Run Process    ${PYTHON}    ${HELPER}    correction-diff-no-changeset    cwd=${WORKSPACE}
    Log    ${result.stdout}
    Log    ${result.stderr}
    Should Be Equal As Integers    ${result.rc}    0
    Should Contain    ${result.stdout}    correction-diff-no-changeset-ok

Correction Diff Returns Output For Plan With Changeset
    [Documentation]    correction_diff returns diff output when a changeset exists
    ${result}=    Run Process    ${PYTHON}    ${HELPER}    correction-diff-with-changeset    cwd=${WORKSPACE}
