Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
Two gateway fixes:
1. MessageDeduplicator.is_duplicate() now checks TTL at query time (#10306)
Previously, is_duplicate() returned True for any previously seen ID
without checking its age — expired entries were only purged when cache
size exceeded max_size. On normal workloads that never overflow, message
IDs stayed deduplicated forever instead of expiring after the TTL.
Fix: check `now - timestamp < ttl` before returning True. Expired
entries are removed and treated as new messages.
2. Gateway --config flag now uses yaml.safe_load() (#10216)
The --config CLI flag in gateway/run.py main() used json.load() to
parse config files. YAML is the only documented config format and
every other config loader uses yaml.safe_load(). A YAML config file
passed via --config would crash with json.JSONDecodeError.
