The record · how to read it

How to read any record

Every record on this site — a contractor's cost estimate, an air permit, a water-discharge screen — is read the same five ways. Learn the grammar once and you can check any figure on the site yourself. Nothing below is summarized for you: each is a real record, read from the published bundle, with its evidence class on every line.

The five beats

One transformation — source → structured read → meaning → verify → connect — applied to whatever the record happens to be:

The source — the artifact and its provenance, messiness left visible
What we read — the structured extraction, each value's confidence shown
What it reveals — plain meaning, with the one load-bearing number called out
How to check it — the evidence tag and a link to verify it at the source
Where it connects — doors into the rest of the library

The evidence classes

Beat ④ hangs on one vocabulary. Every figure carries its evidence class — read it as a confidence signal, not decoration:

Evidence tags

[verified]
Read from a cited record or a live source — confirmed and reproducible.
[inference]
A labelled reading or derivation from cited inputs — reasoning, not a record.
[reference]
An outside published specification or dataset — authoritative, but not a record about this site.
[open]
Withheld, unresolved, or not yet checked — a question, not a verdict.

One grammar, three record types

Switch between three genuinely different records below. The artifact changes; the five beats don't. Each is a real extraction — the in the published bundle badge marks the ones whose figures are read live from the same row the library renders.

③ What it reveals

The public's road package is priced to the dollar — $14,223,081 — yet drainage is just 7.5% of it, the only one of six items detailed, with no design-storm basis and no detention shown. A number that precise on a scope that thin is the tell.

③ What it reveals

The permit fixes the plant's shape exactly — three matched groups of generators and cooling towers, 114 data-hall gensets — yet locks the one number that sets its true scale, per-engine power, as a trade secret. The ~313 MW everyone cites is the draft public-notice figure; the issued permit will not confirm it.

the lock

Engine make / model / size — and so the per-engine ekW that sets the plant's true electrical scale — is claimed as a trade secret and withheld from the issued permit.

The permit fixes the plant's shape exactly — 114 data-hall gensets and 36 cooling towers in three matched groups — yet locks the one number that would let you compute its real backup capacity. The ~313 MW everyone cites is the draft public-notice figure; the issued permit will not confirm it. The scale is set; the proof is withheld.

③ What it reveals

Ohio EPA sizes every discharge against the stream's design low flow — and the Ottawa this project discharges into runs at just 0.2 cfs, dropping to zero in the driest weeks. The tributaries are worse: American II's own fact sheet states a dilution of barely 1.3 to 1. The receiving water is near-undiluted before this project adds a drop.
