## Summary
Removes the Modal-based distributed execution machinery
(`COGNEE_DISTRIBUTED`) from cognee:
- **`distributed/` package** — Modal app, image, queues, signal, graph
write batching, queued-write tasks, and the data-point/graph saving
workers. **`distributed/deploy/` is intentionally kept**: those are the
one-click API-server deployment templates (Modal, Fly.io, Railway,
Render, Daytona) referenced from the README deployment table, unrelated
to distributed execution.
- **Pipeline wiring** — `run_tasks_distributed.py` and the
`override_run_tasks` / `COGNEE_DISTRIBUTED` env switch in
`run_tasks.py`.
- **Adapter hooks** — `@override_distributed` queue-diversion decorators
and `distributed.*` imports in the Neo4j adapter
(`add_nodes`/`add_edges`) and PGVector adapter (`create_data_points`).
- **Packaging** — the `distributed` extra (modal dependency) and the
`distributed` wheel package in `pyproject.toml`; `uv.lock` rebuilt
(modal + ~20 transitive deps dropped).
- **CI / Docker** — `distributed_test.yml` workflow, the
informational-only `distributed-tests` job in `test_suites.yml`, the
`COPY ./distributed` Dockerfile layer, and `--extra distributed` in
`Dockerfile.ci`.
- **Tests / docs** — queue-task and write-batch unit tests
(`test_islo_sandbox.py` kept — it tests the deploy templates); extras
lists in `CLAUDE.md`, `AGENTS.md`, `cognee-mcp/README.md`; stale comment
in `add_data_points.py`.
## Verification
- `ruff check` (pinned v0.15.11) clean on all touched Python files;
`ruff format --check` unchanged vs dev.
- `import cognee`, `run_tasks`, and the Neo4j adapter import cleanly;
PGVector adapter compile-checked (venv lacks optional asyncpg).
- `cognee/tests/unit/modules/pipelines`: **67 passed**.
- Repo-wide grep confirms no remaining references to
`run_tasks_distributed`, `override_distributed`, `COGNEE_DISTRIBUTED`,
or the removed extra.
Closes COG-6100
