kshitijk4poor 66827f8947 chore: prune unused imports and duplicate import redefinitions
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

Stress / battle-test suite

Long-running tests that exercise the Kanban kernel under adversarial conditions. Not run by scripts/run_tests.sh because they can take 30+ seconds each and spawn real subprocesses.

Run manually:

./venv/bin/python -m pytest tests/stress/ -v -s
# or individual files:
./venv/bin/python tests/stress/test_concurrency.py
./venv/bin/python tests/stress/test_subprocess_e2e.py
./venv/bin/python tests/stress/test_property_fuzzing.py
./venv/bin/python tests/stress/test_benchmarks.py

What's covered

  • test_concurrency.py — 5 workers, 100 tasks, race-for-claim. Asserts no double-claims, no orphan runs, no SQLite errors escape retry.
  • test_concurrency_mixed.py — 10 workers + 1 reclaimer, 500 tasks, random ops (claim/complete/block/unblock/archive). Same invariants under adversarial scheduling.
  • test_concurrency_reclaim_race.py — TTL < work duration so the reclaimer intentionally yanks tasks mid-work; verifies the worker's late-complete is refused cleanly (CAS guard works).
  • test_subprocess_e2e.py — dispatcher spawns real Python subprocess workers that heartbeat + complete via the CLI; crash detection against a real dead PID.
  • test_property_fuzzing.py — 500 random operation sequences, ~40k operations total, 9 invariant checks after each step.
  • test_atypical_scenarios.py — 28 scenarios covering atypical user inputs: unicode/emoji/RTL, 1 MB strings, SQL injection attempts, cycles, self-parents, wide fan-in/out, clock skew, HERMES_HOME with spaces/unicode/symlinks, 1000 runs on one task, idempotency-key race across processes, terminal-state resurrection attempts, dashboard REST with weird JSON.
  • test_benchmarks.py — latency at 100/1k/10k tasks for dispatch, recompute_ready, list_tasks, build_worker_context, etc. Results saved to JSON for regression diffing.
