ProvBench — C2PA binding survival under transforms

ProvBench — C2PA binding survival under transforms, with the bound stated honestly. provbench-canonical-bound.json records the finding in its own words: 0 of 20 assets survived binding-intact across the killing transforms (jpeg_reencode, strip_metadata), with a rule-of-three 95% upper bound of 15.0% and Wilson one- and two-sided upper bounds beside it, plus the note that cells cluster by (asset, binding) so a naive pooled CI does not apply. reconciliation names the three earlier numbers this run supersedes and why. A zero result with a stated upper bound is a measurement; a zero reported as "0.000" would not be.

Superseded as a live bank; kept so inbound links resolve.

The live board is the authority

GET https://councilof.ai/api/gspc — quote totals.public_count. This Hub card is a printer of that GET, never a second engine. If the fetch fails the honest answer is UNCHECKABLE — never a fabricated 0.000. Status words: LOADING / UNREACHABLE / UNMEASURED / UNCHECKABLE.

Lid: 22 axes measured · 14 model fleets · 3 public leader scores · 8 fact runs · TIE is TIE · not a certificate.
