+# Architect Artefact — Feature: F-003
+
+## SDD Changes
+- Added `spec/sdd/decisions/003-replace-raw-sql-with-sanitized-dev-baseline.md`
+- Extended product, tech, and acceptance specs for F-003
+- Will update development baseline component doc to reflect sanitized synthetic dataset
+
+## BDD Coverage
+- Added `spec/bdd/features/data/sanitized-sql-baseline.feature`
+- Coverage target:
+  - tracked SQL baseline is sanitized
+  - private local data handling is documented
+
+## Technical decisions
+- Keep the current tracked SQL path for compatibility.
+- Replace raw snapshot content with a small sanitized baseline.
+- Seed only the tables and sample data needed by the legacy PHP module.
+
+## Risks found
+- Raw dump still exists in git history from earlier commits.
+- Synthetic baseline may not cover every future workflow without more fixtures.
+
+## Next step
+- Replace tracked SQL file content with safe synthetic baseline.
+- Add SQL handling docs and ignored path guidance.
