Sources — records for every figure on this page (39 figures)

The 39 rows below are exactly the facts the evidence-backed sections of this page printed — the 10-second verdict, the MoonshotScore, price and market value, the five questions with their receipts, and the records behind this page. Known dates and sources are recorded on their own rows; an em dash or UNRECORDED tier preserves a stored observation without inventing either. The quarterly income statement is provider-standardized (FMP) under one row, and scale definitions — a 0-100 rating, the band ladder, the Piotroski 0–9 range — are fixed rather than measured. No number in those sections was generated by a model. The register does not cover quoted third-party headlines, the dated council readings, or the Frequently Asked Questions; each of those says where it came from where it stands.

"As of" is the date the value is true for where the source carries one — a quarter end, a filing date, a price close, the day the score was computed. A cached observation with no source date remains undated; the page publication date is not used as a substitute.
