Corrections

A public log of what we got wrong

Security content decays fast, and this field moves faster than most. Every correction is logged here with a date, what it said before, what it says now, and how the error got in.

Lands in build stage 3h

Every substantive correction, dated, with what changed and why.
Regulatory and standards content is re-verified quarterly; the threat-landscape track monthly.
Where good sources disagree, we publish ranges with per-figure attribution instead of picking one and presenting it as settled.
