Completes the route-DB pipeline that is the realistic path to 100% under the prose-only / independent constraint (pure RAD-prose synthesis can't guarantee 100% on arbitrary pairs): - discover: synthesize -> oracle-validate -> store if no-error -> reuse instantly next time (verified: 2nd LFPG-EDDF returns via "reused stored IFPS-valid route", 0 IFPUV calls). - learn --from --to --route --fl: validate a user-supplied route against IFPUV and, if no-error, record it (source=ifps, ifps_ok=1) so discover reuses it forever. --force keeps a still-erroring route for review (source=manual, not reused). This is how a real ops route DB grows and how the pairs the generator can't yet crack reach 100% (seed once). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
