1. Scope the repo and time window (optional `--since/--until`).
2. Decide sensitivity rules (use defaults or provide a CSV config).
3. Build the ownership map with `scripts/run_ownership_map.py` (co-change graph is on by default; use `--cochange-max-files` to ignore supernode commits).
4. Communities are computed by default; graphml output is optional (`--graphml`).
5. Query the outputs with `scripts/query_ownership.py` for bounded JSON slices.
6. Persist and visualize (see `references/neo4j-import.md`).
By default, the co-change graph ignores common “glue” files (lockfiles, `.github/*`, editor config) so clusters reflect actual code movement instead of shared infra edits. Override with `--cochange-exclude` or `--no-default-cochange-excludes`. Dependabot commits are excluded by default; override with `--no-default-author-excludes` or add patterns via `--author-exclude-regex`.
If you want to exclude Linux build glue like `Kbuild` from co-change clustering, pass:
```bash
python skills/skills/security-ownership-map/scripts/run_ownership_map.py \
--repo /path/to/linux \
--out ownership-map-out \
--cochange-exclude "**/Kbuild"
```
