# Causal Design > Design and audit identification strategies for observational causal inference. ## Output Path Per `rules/review-artefact-routing.md` (auto-loads in research projects (path-scoped to `paper-*/` and `paper/`)): - **Source slug:** `causal-design` - **Write reports to:** `reviews/<scope>/causal-design/<YYYY-MM-DD-HHMM>.md` inside the project, where `<scope>` is the paper slug (e.g. `paper-philtech`) for paper-level audits or `_project` for project-level reviews. Path is relative to the research project root, not the Task-Management repo. - **Never** at project root (`./CRITIC-REPORT.md`-style filenames are forbidden — pre-rule layout). - **Idempotency:** if today's timestamp exists, append a same-day descriptor to the path base (`{date}-HHMM-revision.md`, `{date}-HHMM-r2.md`, `{date}-HHMM-pre-submission.md`) — never overwrite. - **Index update:** if `reviews/INDEX.md` exists, write a one-line entry under "Latest per source" pointing at the new file. Otherwise `review-recap` will rebuild the index next time it runs. - **Infrastructure repos** (Task-Management, atlas-workspace, etc.): this section does not apply — the path-scoped rule won't load there. ## Modes | Mode | What it does | Entry point | |------|-------------|-------------| | **Design** | Interview-driven strategy selection and memo production | "Design my causal strategy" / "What identification can I use?" | | **Audit** | 4-phase causal inference check on existing paper/scripts | "Check my ident...
