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Superseded as a live bank; kept so inbound links resolve.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

Caveat: do not fuse card_index axes (16) with board axes (23) or Hub cells (384); they are three different counts. Per-card values are point-in-time; never compare a card's accuracy to the live board as one number. RunPod pod outputs are UNSIGNED and are not counted or cited.

Smithery / MCP Connect (measured 2026-10-05 — not a certification)

• Primary Connect (free tools): https://councilof.ai/mcp — initialize 200; call tools/list. Prefer this URL in every agent config.
• Smithery discovery: https://smithery.ai/servers/csoai/gspc-mcp — external release lists upstream https://councilof.ai/mcp. Registry deploymentUrl remains the Smithery gateway (https://gspc-mcp--csoai.run.tools); POST without bearer → 401. That is gateway-by-design — do not claim the registry points at the council door.
• Stale duplicate csoai/gspc: UI /servers/csoai/gspc 404 after unlist attempt; registry row may still exist with run.tools 401. Prefer only csoai/gspc-mcp for discovery.
• Measurement only. Never invent that registry deploymentUrl equals councilof.ai/mcp. Never certify.
