 "grain_reason": "CENTURION PIPELINE: a GATHERING system, on the Harvest Midstream argument (gathering has no nameplate because it has no single bore) and with more evidence than Harvest had. 2,617 `lease` rows across 234 distinct leases, plus 109 truck receipts into Andrews Station from 12 counterparties (both as measured 2026-08-19): trucks and leases are not a line's traffic. 76 facilities across 11 districts (02, 03, 04, 05, 06, 7B, 7C, 08, 8A, 09, 10). The split is the shape of a gathering network rather than a trunk -- other_delivery 183 rows / 240.7 MMBBL, other_receipt 885 / 166.8, lease 2,617 / 63.7. ONE ROW OF IT IS THE CENTURION EDGE, WIRED 2026-10-19 BY HQ RULING (T1_CORRIDOR_SLICE): the filer's own delivery out of Texas, counterparty Centurion Pipeline itself at facility 'Oklahoma' under the centred EXPORTS banner -- the long-haul line crossing into its Oklahoma segment toward Cushing, one row a month, against the pair's published '170,000 barrels per day (bpd) combined' (Reuters, 2019). The rest of the book is gathering and stays system grain. CORRECTED THE SAME DAY: this reason said, from 2026-08-19, that there was no Cushing delivery in the filing at all; that held only until the banner reader learned the centred EXPORTS heading, and the 'still no row names Cushing' re-measures below are kept as history -- the row names Oklahoma, not Cushing. Note the total, 471.3 MMBBL over 12 months = 1,291 MBBL/D against the 1,500 network.yaml then used, is 0.86x -- A PLAUSIBLE RATIO IS NOT EVIDENCE OF LINE GRAIN, it is what an aggregate of the right rough size looks like, and it was the reason this filer sat 'plausibly line-grain' and unassigned for a fortnight. Ruled 2026-08-19. Re-measured 2026-09-27 after two more months arrived: the span widened from four districts to six (03 and 06 are new), and there is STILL not one row naming Cushing, so the ruling's decisive fact is untouched. The ratio moved 0.9x to 0.84x and means as little as it did. Re-measured 2026-09-29, when short sections began publishing their lines: facility keys 60 -> 65, six districts -> eleven, other_receipt 815 -> 885 rows, the ratio 0.84x -> 0.86x -- and still no row names Cushing. Re-measured 2026-10-08 after the 2025-01 re-read: facility keys 65 -> 76, volume and districts unchanged. That re-read splits facilities out of welded counterparty names (C-Ranch North and South, Pegasus Trucks, 'from Enterprise'), three of them with scanner residue ('Maliet Station Trucks', 'Midland Trucks ee', '7 Halley Station Trucks'); still no row names Cushing.",
