v3	2026-09-28	The Goodhart's law sentence now states the law as Goodhart worded it, 'any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes', and notes that the familiar 'when a measure becomes a target, it ceases to be a good measure' is Strathern's (1997) later generalization. Added a footnote for Strathern (1997), 'Improving Ratings': Audit in the British University System.	prose — detailed body (prose edited)
v2	2026-09-28	The footnote for Goodhart's law now cites 'Problems of Monetary Management: The U.K. Experience' (1975), the paper where the law is stated, instead of a companion paper from the same volume; its dead link was replaced.	prose — detailed body (prose edited)

Editions are cut at publish time from a content hash of the entity's canonical source, so a version changes only when the content actually changed. Full canonical content for every edition, and the exact per-part diffs between them, are in the downloadable editions archive (editions_archive.jsonl); the current-state index is versions.jsonl.
