Feature: ACMS service coverage round 3 — protocol stubs and default packer
  As a developer maintaining the ACMS pipeline
  I want to exercise uncovered protocol stub bodies and the DefaultBudgetPacker
  So that the test suite covers lines 34-35, 112, 120, 124, 275, 292, 309, 396, 577

  # -----------------------------------------------------------------------
  # Lines 34-35: TYPE_CHECKING imports (Settings, UnitOfWork)
  # These are behind `if TYPE_CHECKING:` and not executable at runtime.
  # We validate the DI path that accepts those types as constructor args.
  # -----------------------------------------------------------------------

  Scenario: Pipeline accepts settings and unit_of_work constructor params
    Given ascov3 I have mock Settings and UnitOfWork objects
    When ascov3 I create a pipeline with settings and unit_of_work injected
    Then ascov3 the pipeline should store the injected dependencies

  # -----------------------------------------------------------------------
  # Line 112: ContextStrategy.can_handle protocol default body (Ellipsis)
  # -----------------------------------------------------------------------

  Scenario: ContextStrategy protocol default can_handle returns None
    Given ascov3 I have a bare ContextStrategy subclass
    When ascov3 I call can_handle on the bare strategy with an empty request
    Then ascov3 the can_handle result should be None

  # -----------------------------------------------------------------------
  # Line 120: ContextStrategy.assemble protocol default body (Ellipsis)
  # -----------------------------------------------------------------------

  Scenario: ContextStrategy protocol default assemble returns None
    Given ascov3 I have a bare ContextStrategy subclass
    When ascov3 I call assemble on the bare strategy with empty fragments and a budget
    Then ascov3 the assemble result should be None

  # -----------------------------------------------------------------------
  # Line 124: ContextStrategy.explain protocol default body (Ellipsis)
  # -----------------------------------------------------------------------

  Scenario: ContextStrategy protocol default explain returns None
    Given ascov3 I have a bare ContextStrategy subclass
    When ascov3 I call explain on the bare strategy
    Then ascov3 the explain result should be None

  # -----------------------------------------------------------------------
  # Line 275: StrategySelector.select protocol default body (Ellipsis)
  # -----------------------------------------------------------------------

  Scenario: StrategySelector protocol default select returns None
    Given ascov3 I have a bare StrategySelector subclass
    When ascov3 I call select on the bare selector with empty strategies
    Then ascov3 the select result should be None

  # -----------------------------------------------------------------------
  # Line 292: BudgetAllocator.allocate protocol default body (Ellipsis)
  # -----------------------------------------------------------------------

  Scenario: BudgetAllocator protocol default allocate returns None
    Given ascov3 I have a bare BudgetAllocator subclass
    When ascov3 I call allocate on the bare allocator with empty candidates
    Then ascov3 the allocate result should be None

  # -----------------------------------------------------------------------
  # Line 309: StrategyExecutor.execute protocol default body (Ellipsis)
  # -----------------------------------------------------------------------

  Scenario: StrategyExecutor protocol default execute returns None
    Given ascov3 I have a bare StrategyExecutor subclass
    When ascov3 I call execute on the bare executor with empty allocations
    Then ascov3 the execute result should be None

  # -----------------------------------------------------------------------
  # Line 396: SkeletonCompressor.compress protocol default body (Ellipsis)
  # -----------------------------------------------------------------------

  Scenario: SkeletonCompressor protocol default compress returns None
    Given ascov3 I have a bare SkeletonCompressor subclass
    When ascov3 I call compress on the bare compressor with empty fragments
    Then ascov3 the compress result should be None

  # -----------------------------------------------------------------------
  # Line 577: DefaultBudgetPacker.pack returns fragments unchanged
  # -----------------------------------------------------------------------

  Scenario: DefaultBudgetPacker pack returns fragments unchanged
    Given ascov3 I have a DefaultBudgetPacker instance
    And ascov3 I have a list of test fragments
    When ascov3 I call pack on the packer with those fragments and a budget
    Then ascov3 the pack result should be the same fragments unchanged

  Scenario: DefaultBudgetPacker pack returns empty sequence for empty input
    Given ascov3 I have a DefaultBudgetPacker instance
    When ascov3 I call pack on the packer with empty fragments and a budget
    Then ascov3 the pack result should be an empty sequence
