How to read this library
Claims are labeled by confidence
Standards and platform policies change. Each technical tool should state its source, scope, review date, and method. Until a calculation has public fixtures and review evidence, it should not be described as formal compliance certification.
Reference
Summarizes a primary standard, policy, or published platform recommendation.
Estimated
Useful for planning or education, but not a substitute for a formal delivery meter or human review.
Validated
Backed by published fixtures, tolerances, and a documented comparison or review process.
Experimental
A working prototype whose behavior or method is still being evaluated.

Review and corrections
Every standards-sensitive page should show an owner, reviewer, sources, applicable version, last reviewed date, supported scope, and known limits. Report a factual or accessibility issue through the corrections process. Material corrections should be documented in the page changelog.
