+# Public docs and national validation refresh v0.10.7.5
+
+## Summary
+
+This document records the public documentation refresh and validation state after the Andalucía distributor research pipeline work.
+
+## Current public version
+
+- VERSION: v0.10.6.4-distributor-confidence-labels
+- Public distributor JSON version expected: v0.10.6.4-distributor-confidence-labels
+- Public distributor hint zones: 2610
+
+## Andalucía distributor research baseline
+
+- Andalucía municipal GeoJSON source: frontend/public/data/andalucia_municipios.geojson
+- Andalucía GeoJSON features: 786
+- Existing public Andalucía distributor hints: 254
+- Pending municipal review queue rows: 532
+- Batch 2 candidate workbench rows: 532
+
+## Current Andalucía guard scripts
+
+- scripts/check_andalucia_pending_review_queue.py
+- scripts/check_andalucia_batch2_candidate_workbench.py
+
+## Current public/version guard scripts
+
+- scripts/check_distributor_data_version.py
+- scripts/check_public_deploy_smoke.py
+- scripts/run_public_smoke_expected_version.sh
+- scripts/check_public_docs_freshness.py
+
+## National coverage checks to keep running
+
+- node --check frontend/src/geo/datasets.js
+- python3 scripts/check_all_scope_datasets.py
+- python3 scripts/audit_geo_datasets.py
+- python3 scripts/check_spain_geo_coverage.py
+- bash scripts/repo_guard.sh --no-build
+- npm --prefix frontend run build
+
+## Safety constraints
+
+The refreshed docs and guards must not add:
+
+- CUPS.
+- Addresses.
+- Exact user coordinates.
+- Customer data.
+- Private grid inventory.
+- Raw external API responses.
+- Secrets, tokens, logs or backups.
+
+## Next safe data step
+
+The next data step should select a small, source-backed Andalucía subset from the batch 2 workbench and manually review it before any import.
+
+No automatic import should be performed from the workbench.
