Schema

Field	Type	Meaning
date	ISO date	Date of the action as announced by the actor, not the date of coverage.

actor_type	enum	One of Central Bank, Chipmaker, Enterprise, Lab, Multilateral, Platform, Regulator, Sovereign .
action	string	Short verb phrase, at most eight words.
magnitude	string	The stated magnitude in the actor's own units, or an em dash for policy without a figure.
usd_b	number or null	Headline dollar figure in billions, at the announcement-date rate. Null when there is no dollar figure. This is what sizes the dots and sorts the table.
gw	number or null	Stated power capacity in gigawatts, where the announcement includes one.
summary	string	One factual sentence, at most 25 words, no adjectives.
source_name, source_url	string	The primary source. Filings, releases, and government sites are preferred; tier-one press otherwise.

What the ledger is and isn't

It records actions with a stated economic magnitude by institutions: labs, platforms, sovereigns and sovereign funds, central banks, multilaterals, regulators, chipmakers, and large enterprises. Magnitudes are as announced and are not adjusted for what's been deployed; the analyses treat that gap directly. It is selective, not exhaustive: the test for inclusion is whether the action changes the economics of the buildout, not whether it made news. Corrections and additions to hello@kylewisniewski.com.
