(journal page 372, PDF page 4). All 28 ions in
`src/flahax/data/conductivity_mccleskey2012.json` match the printed Eq. 8

(40.70, 0.8770, 19.20, 0.6070, 80.50, 2.090, 68.10, 39.90, 35.90, 54.80,
4.390, 48.20, 6.210, 0.8730) are the same values as the JSON numbers.
The independent fixture matches the shipped file, and
`tests.test_irrigation_ec.CoefficientTests` passed (5 tests).

This is the M1 Table 1 check. It does not decide O1, O2 or O3, and it
does not start M2 or M3.

| Assay charge residual ≤ 0.1 % (declared forms) | **26 of 26** (recount 2026-10-19; was 15 of 26) | All pass after the traceable-catalogue corrections: Mg Nitrate D1, chelate sodium D2, borax declared form. Worst −0.05 % (Tropical Lettuce). The 2026-10-18 count was 15 of 26, worst −0.32 %, from rounded label assays and undeclared chelate counterions. |
| `supplied` pH 5.8 with no recorded reagent | 0 of 26 | Speciated imbalance 0.3–6 %: the target pH implies an acid or base dose that was not recorded. Correct `partial` behaviour, and a reason for `EquilibriumPhPlan` input. |
| Charged chelate and trace complexes covered | 0 of 26 without O2 | Micromolar FeEdta⁻ and others make nearly every recipe `partial` unless covered or bounded under O2. |

So the M2 exit ("typical catalogue recipes return `estimated`") also needs
the reagent dose recorded and, for `calculated` mode, either assay
corrections in the catalogue or acceptance that those 11 formulas stay
`not_supported`. McCleskey's −0.7 ± 5 % over 1,593 natural waters is
the reagent dose recorded. The catalogue corrections have now met the
`calculated`-mode assay condition. In a 2026-10-19 recount in declared RO
water at calculated pH, all 26 formulas are still `partial` /
`missing_species_contributions`. The causes are phosphate species, citrate
pairs, CaNO₃⁺, MgH₂PO₄⁺/CaH₂PO₄⁺, NH₄SO₄⁻, Fe-EDTA species and trace
MgOH⁺/CaOH⁺, which await O1 and O2. McCleskey's −0.7 ± 5 % over 1,593 natural waters is
literature context, never an accuracy claim for these mixtures.
