What survived the check — each claim with the passage that supports it
A strong validator is representation metadata that changes value whenever a change occurs to the representation data that would be observable in the content of a 200 (OK) response to GET.
rfc9110#8.8.1 — 100% of
this claim's content words appear in that passage.
A weak validator is representation metadata that might not change for every change to the representation data.

this claim's content words appear in that passage.
Strong validators are ideal for comparisons but can be very difficult, and occasionally impossible, to generate efficiently.
rfc9110#8.8.1 — 100% of
this claim's content words appear in that passage.
Weak validators are easy to generate but are far less useful for comparisons.
rfc9110#8.8.1 — 100% of

A strong validator is unique across all versions of all representations associated with a particular resource over time.
rfc9110#8.8.1 — 100% of
this claim's content words appear in that passage.
A validator is weak if it is shared by two or more representations of a given resource at the same time, unless those representations have identical representation data.

rfc9110#8.8.1 — 100% of
this claim's content words appear in that passage.
