* feat(supply-chain): energy flow estimates per chokepoint (mb/d card row) - Add FlowEstimate proto message + ChokepointInfo field 15; regenerate stubs - Add baselineId mapping to _chokepoint-ids.ts (7 of 13 chokepoints) - Add relayId to seed-chokepoint-baselines.mjs CHOKEPOINTS entries - New seed-chokepoint-flows.mjs: reads portwatch + baselines, computes 7d tanker avg vs 90d baseline, outputs flow_ratio and current_mbd; prefers DWT (capTanker) when available; flags disruption if last 3 days each below 0.85 threshold; writes energy:chokepoint-flows:v1 (TTL 3d) - get-chokepoint-status.ts: parallel-reads flows key, attaches flowEstimate - SupplyChainPanel: compact card gains mb/d row (red <85%, amber <95%) - 19 new unit tests for flow computation and seeder contract * fix(chokepoint-flows): base useDwt on 90d baseline window, not recent 7 days Zero recent capTanker is the disruption signal, not a reason to fall back to vessel counts. Switching metrics during peak disruption caused the seeder to report a higher (less accurate) flow estimate exactly when oil-flow collapse is most acute. useDwt is now locked to whether the baseline window has DWT data -- stable across disruption events. Adds regression test covering DWT-collapse scenario. * fix(chokepoint-flows): require majority DWT coverage in baseline before activating DWT mode capBaselineSum > 0 would activate DWT on a single non-zero day during partial data roll-out, pulling down the baseline average via zero-filled gaps. Now requires >= ceil(prev90.length / 2) days with DWT data. ArcGIS data is all-or-nothing per chokepoint in practice, so this guard catches edge cases without affecting normal operation.
