Corrections log
When a published number turns out to be wrong, the fix is recorded here: the date, the page, and what changed. The build-time checks along the way are described at how we check the numbers.
No corrections have been logged yet. That is the state this site aims for: every dosing constant is re-verified against its source at build time, so drift gets caught before it ships rather than after someone soaks in it.
