The oracle-validated route DB (the realistic path to 100% under prose-only) lived only in the gitignored real.db, so a navdata rebuild would lose it. Now it is portable and version-controlled: - routes::export_validated -> TSV of every ifps_ok route (one per pair); import_seeds loads them back as reusable seeds (source=seed). - CLI `export-routes` / `import-routes`. - discover reuse now matches any ifps_ok route (not just source=ifps), so imported seeds are reused instantly (verified round-trip). - data/validated_routes.tsv: 65 validated European city-pair routes, built by bulk-seeding discover over ~85 common pairs (the DB grew ~11 -> 65). This is the PFPX-style route DB, committed: 65 pairs are now no-error & instant on any machine; `learn` + more bulk-seed grow it further. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
