Feature: Container module coverage round 2
  As a developer maintaining container.py
  I want every uncovered line and branch exercised
  So that container.py achieves full coverage

  # -------------------------------------------------------------------
  # get_ai_provider – non-mock paths (lines 51 False, 66-67, 69)
  # -------------------------------------------------------------------

  Scenario: AI provider returns None when mock disabled and no providers configured
    Given r2cont- the mock AI environment flag is disabled
    And r2cont- a provider registry with no configured providers
    When r2cont- I call get_ai_provider with the mocked registry
    Then r2cont- the ai provider result should be None

  Scenario: AI provider returns real provider when mock disabled and providers exist
    Given r2cont- the mock AI environment flag is disabled
    And r2cont- a provider registry with configured providers
    When r2cont- I call get_ai_provider with the mocked registry
    Then r2cont- the ai provider result should not be None

  # -------------------------------------------------------------------
  # get_ai_provider – features path already on sys.path (line 57 partial)
  # -------------------------------------------------------------------

  Scenario: AI provider with features path already on sys.path does not duplicate it
    Given r2cont- the mock AI environment flag is enabled
    And r2cont- the features path is already on sys.path
    When r2cont- I call get_ai_provider without registry args
    Then r2cont- the features path should appear exactly once on sys.path

  # -------------------------------------------------------------------
  # _build_project_resource_link_repo (lines 125-130)
  # -------------------------------------------------------------------

  Scenario: Build project resource link repo creates valid repository
    When r2cont- I build a project resource link repo with an in-memory database
    Then r2cont- the result should be a ProjectResourceLinkRepository instance

  # -------------------------------------------------------------------
  # get_database_url – env var branches (lines 82, 87)
  # -------------------------------------------------------------------

  Scenario: get_database_url returns fallback when no env vars are set
    Given r2cont- no database URL environment variables are set
    When r2cont- I call get_database_url
    Then r2cont- the database URL should start with "sqlite:///"

  Scenario: get_database_url returns CLEVERAGENTS_DATABASE_URL when set
    Given r2cont- the env var "CLEVERAGENTS_DATABASE_URL" is set to "sqlite:///explicit.db"
    When r2cont- I call get_database_url
    Then r2cont- the database URL should be "sqlite:///explicit.db"

  Scenario: get_database_url returns CLEVERAGENTS_TEST_DATABASE_URL when primary is unset
    Given r2cont- the env var "CLEVERAGENTS_DATABASE_URL" is cleared
    And r2cont- the env var "CLEVERAGENTS_TEST_DATABASE_URL" is set to "sqlite:///test.db"
    When r2cont- I call get_database_url
    Then r2cont- the database URL should be "sqlite:///test.db"

  Scenario: get_database_url skips empty env var values
    Given r2cont- the env var "CLEVERAGENTS_DATABASE_URL" is set to empty
    And r2cont- the env var "CLEVERAGENTS_TEST_DATABASE_URL" is set to empty
    When r2cont- I call get_database_url
    Then r2cont- the database URL should start with "sqlite:///"

  # -------------------------------------------------------------------
  # get_container – cached instance (line 256 False branch)
  # -------------------------------------------------------------------

  Scenario: get_container returns the cached instance on subsequent calls
    Given r2cont- the global container has been reset
    When r2cont- I call get_container twice
    Then r2cont- both calls should return the same container instance

  # -------------------------------------------------------------------
  # override_providers – non-existent attribute (line 285 False)
  # -------------------------------------------------------------------

  Scenario: override_providers ignores non-existent provider names
    Given r2cont- the global container has been reset
    When r2cont- I override a provider with a non-existent name
    Then r2cont- no error should have been raised

  # -------------------------------------------------------------------
  # override_providers – non-database_url provider (line 288 else)
  # -------------------------------------------------------------------

  Scenario: override_providers handles non-database_url providers via Object
    Given r2cont- the global container has been reset
    When r2cont- I override the settings provider with a mock value
    Then r2cont- the settings provider should return the mock value
