  "_disclosure": "PUBLISHED GAP — minimum_for_10_cu_m_php is null for the current 2026-03 tranche. No primary or secondary source publishes MPIW's post-March-2026 minimum charge, and it is NOT derivable: the published Tranche-1 minimum is ₱252.02 against a ₱25.20/cu.m. rate, so the minimum is not a clean ten-times multiple and rate × 10 invents a charge MPIW has never billed. A figure of exactly that shape (₱286.70) was removed from the ledger on 2026-07-12. Do not fill this cell. The 11–20 and 21–30 cu.m. tiers are likewise absent: MPIW publishes them only in a stale 2018 image.",

    "No current 0–10 cu.m. minimum charge exists in any source, so this dataset publishes none. A Philippine water bill is built on that minimum, which means these rows do not add up to a monthly bill.",
    "The 11–20, 21–30 and higher consumption tiers are published by MPIW only as a stale November 2018 image and are not seeded here.",
    "The ₱28.67/cu.m. rate reaches the public record only through named secondaries. MPIW's own posted \"latest approved tariff schedule\" is still the 2018 sheet and the MIWD water-rates page is an empty stub.",
    "The two-tranche schedule is complete — there is no Tranche 3 — so the next point is a new adjustment, not a scheduled one.",
    "Service area is the Iloilo City core plus Maasin, Cabatuan, San Miguel, Santa Barbara, Oton, Pavia and Leganes. Residential only; commercial and bulk rates differ."
