Evidence card — WHO data integrity guideline

One card for one tracked entry, carrying the two axes this record keeps on every source, the day the document was last observed, and the address of the entry it describes.

The bytes

These are the whole card. Markup and inline style attributes: no script, no stylesheet, no font file, no image, and no request of any kind back to this site. A page carrying them serves them from its own bytes.

What the card does not carry

States and days, and nothing else. Every address, every retained passage and every digest sits on the entry page, where the checks that assert them can reach them. A copy does not update, which is why the day it was generated is printed on its face rather than implied.

The mechanism, the two refused on the way to it, and the limits of all three are set out on the card index.

The entry this card describes

WHO data integrity guideline — the record this card is drawn from, with the passages, the addresses, the digests and the observation series behind every line above.
