- ml/tests/dqn_training_pipeline_test.rs: the inline TODO speculated about a future `load_checkpoint` hook; loader round-trip coverage already lives in dqn_checkpoint_tests. Reword to point there. - ml/tests/ppo_lstm_training_loop_tests.rs: the assertion on `hidden_state_manager.is_some()` is the public-surface proxy for "LSTM path active"; deeper introspection isn't exposed. Say so. - ml/tests/ppo_recurrent_integration_tests.rs: the test is already `#[ignore]`d; rewrite the inline TODO as a description of the missing `from_varbuilder` constructors on LSTMPolicyNetwork / LSTMValueNetwork. - risk/risk_engine.rs: VarEngine receives a default asset-class config because the schema-to-config conversion is not wired. Reword the TODO to describe that plainly. - trading_engine/types/errors.rs: `common::ConversionError` does not exist; keep ConversionError local and drop the aspirational re-export comment. - trading_engine/tests/audit_persistence_tests.rs: describe why the query assertion only checks the Ok shape (row-to-event mapping not wired) rather than pointing at a nonexistent line number.
