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
Fixtures that instantiate SessionStore() trigger SessionDB() with no args,
which resolves to ~/.hermes/state.db via the DEFAULT_DB_PATH module constant
(snapshot of get_hermes_home() at hermes_state import time).
The autouse _hermetic_environment fixture in tests/conftest.py monkeypatches
HERMES_HOME env, but DEFAULT_DB_PATH is already cached by then. Per-test
monkeypatch.setattr(hermes_state, 'DEFAULT_DB_PATH', tmp_path/'state.db')
forces the DB into tmp_path so the tests can't leak into the real profile.
Verified by counting u1-prefixed sessions in real state.db before/after:
delta=0.
state.db is canonical. The 'use whichever source is longer' branch was
defensive code for the pre-DB migration; on every real DB it has not
fired (verified on a session corpus with 27 jsonl files / 950 sessions —
zero jsonl-bigger cases).
Test changes:
- TestLoadTranscriptCorruptLines: deleted (tested dead JSONL code path)
- TestLoadTranscriptPreferLongerSource: deleted (tested removed fallback)
- Replaced with TestLoadTranscriptDBOnly (DB-only reads)
- TestSessionStoreRewriteTranscript: fixture now creates DB session
- test_gateway_retry_replaces_last_user_turn: fixture uses real DB
The session store was copying the ENTIRE parent DM transcript into new
thread sessions. This caused unrelated conversations to bleed across
threads in Slack DMs.
The Slack adapter already handles thread context correctly via
_fetch_thread_context() (conversations.replies API), which fetches
only the actual thread messages. The session-level seeding was both
redundant and harmful.
No other platform (Telegram, Discord) uses DM threads, so the seeding
code path was only triggered by Slack — where it conflicted with the
adapter-level context.
Tests updated to assert thread isolation: all thread sessions start
empty, platform adapters are responsible for injecting thread context.
Salvage of PR #5868 (jarvisxyz). Reported by norbert on Discord.
