## [Unreleased]
- **fix(test): move advanced context strategy test doubles to features/mocks** (#7574): Extracted `FakeEmbeddings`, `RelevanceScoringStrategy`, `AdaptiveContextSelector`, `ContextFusionStrategy`, and `_pack_budget` from `features/steps/advanced_context_strategies_steps.py` into a new `features/mocks/advanced_context_strategies_mocks.py` file per CONTRIBUTING.md mock-placement rules. Updated the Robot Framework helper `robot/helper_advanced_context_strategies.py` to import directly from `features.mocks` rather than manipulating `sys.path` to reach the Behave steps file. Added `None` guard in `step_assemble_context_query` before calling `selected.assemble()`, and added explicit `ValueError` for unknown strategy types in both `step_load_yaml_strategy` and `load_strategy_from_yaml_impl`.
- **fix(a2a): regression tests for stale cleveragents.acp removal** (#5566): Added two Behave BDD scenarios verifying that `cleveragents.acp` is not importable (raises `ImportError`) and that `src/cleveragents/acp/` does not exist in the source tree. These guard against regression of the `__pycache__`-based import that allowed the removed ACP module to still be loaded from bytecode after the v3.6.0 rename to `a2a`.
- **Virtual Resource Type Base Class** (#8610): Implemented `VirtualResource` base class with two example concrete implementations (`MetricResource`, `APIEndpointResource`) for abstract/computed resources that are derived rather than mapped to physical files. Virtual resources are computed on demand via a `compute_fn` callable. Includes Behave BDD scenarios in `features/resource_virtual_types.feature` exercising construction, computation, name validation, kwargs passthrough, exception handling, string representation, and subclassing. Resource names are validated against `^[a-zA-Z][a-zA-Z0-9_-]*$` (must start with a letter; alphanumeric, hyphens, and underscores otherwise).
- **test(e2e): restore complete M2 acceptance test** (#11191): Restored the truncated M2 full actor compiler and LLM integration e2e acceptance test to its complete 10-step form. Added dynamic LLM provider selection via `Resolve LLM Actor` (falls back to Anthropic when OpenAI is unavailable or quota-exhausted), replacing hardcoded `gpt-4` / `openai/gpt-4` references in the actor config and action YAML. Added explicit return-code validation (`Should Be Equal As Integers ${r_actor.rc} 0`) for the actor registration step.

BLOCKER — Mock class in wrong location

Per CONTRIBUTING.md, all mocks, fakes, stubs, and test doubles must live in features/mocks/ exclusively. FakeEmbeddings is a fake/test-double class and must be moved to features/mocks/fake_embeddings.py (or similar), then imported here.

If RelevanceScoringStrategy, AdaptiveContextSelector, and ContextFusionStrategy are test-only constructs, they also belong in features/mocks/. If they are intended as real production strategy implementations, move them to src/cleveragents/application/services/context_strategies.py and import from there — not defined inline in a step file.

This violation is contributing to the unit_tests CI failure.

BLOCKER — Potential NoneType dereference

selected is initialised to None a few lines above and may still be None here if best_name does not match any strategy in context.assembler_strategies. This call will then raise AttributeError: 'NoneType' object has no attribute 'assemble'.

Fix — add a guard before this line:

if selected is None:
    raise AssertionError(f"No strategy found with name {best_name!r}")

Pyright strict mode will also flag this as a potential None dereference.

BLOCKER — Cross-layer import causing lint failure

This block manipulates sys.path to import from features/steps/, which is the Behave unit-test layer. Robot Framework integration tests must not import from Behave step files.

The # noqa: E402 comment is the direct cause of the CI / lint failure: robot/ files are not listed under [tool.ruff.lint.per-file-ignores] for E402 in pyproject.toml. Ruff will flag this as either a live E402 violation or a RUF100 (unused noqa directive). Either way, the lint job fails.

How to fix: Move AdaptiveContextSelector, ContextFusionStrategy, and RelevanceScoringStrategy to either:

  • features/mocks/ (if test-only constructs), or
  • src/cleveragents/application/services/context_strategies.py (if real production implementations)

Then both the Behave steps and this Robot helper can import from the canonical location, and the sys.path manipulation plus noqa can be removed entirely.
