Stage 3 · Data assurance
Where did this number come from, and can we trust it?
Each value is scored against a confidence threshold and checked by deterministic assurance rules. Nothing uncertain enters a sustainability record without a person confirming it.

Assurance checks (illustrative)
A-01Readable source evidence
The document must be a supported format and not locked or password-protected.
DOCX file opened and read.
A-02Required activity data present
Facility, reporting period, activity type, value and unit are required for every record.
All required values are present.
A-03Confidence at or above threshold
Each value must be extracted with at least 85% confidence (demonstration threshold).
All values meet the threshold.
A-04Unit recognized for activity type
The unit must be a recognized measure for the activity (illustrative unit list).
"therms" is a recognized unit for natural gas.
A-05Implied unit cost is plausible
Invoice amount ÷ activity value must fall in an expected range for the unit (illustrative).
$0.943 per therms is within $0.300–$3.00.
A-06Value reconciles to source rows
The extracted activity value must equal the sum of the line-level rows on the document.
Rows sum to 412,880, matching the extracted value.
A-07No duplicate activity for the period
The same facility, period and activity must not already be recorded from other evidence.
No overlapping record found.
