Observation series — 21 CFR Part 820 — Quality Management System Regulation

← 21 CFR Part 820 (QMSR)

141 observation(s) recorded. 141 carry an address; none is without one. 140 retained normalised text and hold a digest. 1 hold none: 1 where a server answered and no response body was recorded; and none was hashed.

Each observation is addressed by this row’s identifier, the date it was observed, and its sequence within that date — the same key /api/v1/series.jsonl publishes as `sequence`, counted in the order the store recorded them.

This digest is a leaf of the integrity root, and the command that recomputes it is published at /verify/.

Every addressed record below carries its own citation, naming the day, the URL that answered, the response as recorded, and the digest where one exists. Where none exists the citation says so and asserts no digest.

The GXP-OBS statements on the field a column renders: Normalised textcontent_length · The document observation · GXP-OBS version 1What it records Characters of normalised content.What it does not claim It measures the normalisation, not the document, and it is not a measure of how much a document says.Absent or null means Written as 0 wherever no digest was taken. A 0 here is the absence of a measurement and never a measured empty document.In the glossary · GXP-OBS

             tags, scripts, navigation and volatile strings are removed before
             hashing, so hashing the source as served will not reproduce it.

             21,133 characters of normalised text.
             The digest is of the NORMALISED text, not of the bytes served:
             tags, scripts, navigation and volatile strings are removed before
             hashing, so hashing the source as served will not reproduce it.
             Normalisation is described at https://gxplex.com/how/; the command
