+## Preferred Data-Collection Workflow (Decoupled)
+
+Use dedicated run specs for SLM data collection instead of editor sprint plans:
+
+1. Run spec batch + capture:
+   - `tools/mcp/run_spec_batch_with_capture.sh datasets/run_specs`
+2. Spec corpus:
+   - `datasets/run_specs/` (`runspec_*.md` + `index.jsonl`)
+3. Keep sprint plans for editor/product work, not synthetic data generation.

+## Multi-Project Corpus (New)
+
+Use cross-project fixtures and specs to avoid local minima:
+
+1. Fixtures:
+   - `example_projects/`
+2. Specs:
+   - `datasets/example_run_specs/` (`runspec_*.md` + `index.jsonl`)

+4. Novelty loop:
+   - `tools/mcp/run_novelty_churn_loop.sh`
+   - includes project specs when `INCLUDE_EXAMPLE_PROJECT_SPECS=1` (default)
+5. Concurrency fix:
+   - `tools/mcp/run_spec_batch_with_capture.sh` now uses unique batch summary names (`timestamp + pid + random`) to prevent file overwrite in concurrent runs.
