Feature: ConfigService coverage boost for uncovered branches
  Target uncovered lines in config_service.py that existing tests miss:
  resolve() verbose mode with CLI and ENV values, set_project_value
  with empty project name and corrupted TOML data, get_project_overrides
  with corrupted TOML data.

  Background:
    Given a fresh temporary config directory for coverage boost tests

  # -----------------------------------------------------------------------
  # resolve() verbose mode – CLI_FLAG branch (line 1267)
  # -----------------------------------------------------------------------

  Scenario: Resolve with cli_value and verbose produces CLI_FLAG chain entry with value
    Given a coverage boost ConfigService with empty config
    When I resolve "core.log.level" with cli_value "TRACE" and verbose True
    Then the chain should contain a CLI_FLAG entry with value "TRACE"

  # -----------------------------------------------------------------------
  # resolve() verbose mode – ENV_VAR branch (lines 1279-1283)
  # -----------------------------------------------------------------------

  Scenario: Resolve with env var set and verbose produces ENV_VAR chain entry with value and env_name
    Given a coverage boost ConfigService with empty config
    And the coverage boost env var "CLEVERAGENTS_LOG_LEVEL" is injected as "WARN"
    When I resolve "core.log.level" with verbose True and no cli_value
    Then the chain should contain an ENV_VAR entry with value "WARN" and env_name "CLEVERAGENTS_LOG_LEVEL"

  # -----------------------------------------------------------------------
  # set_project_value() empty project name (lines 1404-1405)
  # -----------------------------------------------------------------------

  Scenario: set_project_value raises ValueError when project_name is empty
    Given a coverage boost ConfigService with empty config
    When I call set_project_value with empty project name and key "plan.concurrency" value 8
    Then a ValueError with message "project_name must not be empty" should be raised

  # -----------------------------------------------------------------------
  # set_project_value() corrupted project section – not a dict (line 1415)
  # -----------------------------------------------------------------------

  Scenario: set_project_value handles non-dict project section in TOML gracefully
    Given a coverage boost ConfigService with project section set to a string
    When I call set_project_value for project "myproj" key "plan.concurrency" value 8
    Then the call should succeed without error
    And get_project_overrides for "myproj" should contain key "plan.concurrency"

  # -----------------------------------------------------------------------
  # set_project_value() corrupted project overrides – not a dict (line 1418)
  # -----------------------------------------------------------------------

  Scenario: set_project_value handles non-dict project overrides for a project gracefully
    Given a coverage boost ConfigService with project overrides for "myproj" set to a string
    When I call set_project_value for project "myproj" key "plan.concurrency" value 8
    Then the call should succeed without error
    And get_project_overrides for "myproj" should contain key "plan.concurrency"

  # -----------------------------------------------------------------------
  # get_project_overrides() corrupted project section – not a dict (line 1450)
  # -----------------------------------------------------------------------

  Scenario: get_project_overrides returns empty dict when project section is not a dict
    Given a coverage boost ConfigService with project section set to a string
    When I call get_project_overrides for project "myproj"
    Then the coverage boost result should be an empty dictionary

  # -----------------------------------------------------------------------
  # get_project_overrides() corrupted project data – not a dict (line 1453)
  # -----------------------------------------------------------------------

  Scenario: get_project_overrides returns empty dict when project data for name is not a dict
    Given a coverage boost ConfigService with project overrides for "myproj" set to a string
    When I call get_project_overrides for project "myproj"
    Then the coverage boost result should be an empty dictionary
