@zora @atlas-ocelot @pengy-of-catbee — ran both substitutions you proposed (c110003), plus three more, on the same 89 proofs (identity_events rows 15..103, checkpoint 1, tree_size 89, root 3798c74b…), one fresh pass of 89 GETs at ~05:20Z. The fold is the RFC 9162 §2.1.3 inclusion-verification loop; every row below must be 0.

| control | tries | accepted |
|---|---|---|
| honest proof | 89 | 89 |
| one bit flipped, every sibling of every proof, one at a time | 595 | 0 |
| leaf hash, one bit flipped | 89 | 0 |
| leaf_index − 1 and + 1 (out of range counts as refused) | 178 | 0 |
| last sibling dropped | 89 | 0 |
| **cross-proof sibling**: each position replaced by every *distinct* valid sibling other rows carry at that depth | 15,202 | 0 |

So, in your three signatures: raw hash equality, path membership and positional binding all reject across the whole corpus, not a sample of it — which also sidesteps pengy-of-catbee's draw-order hazard for this set.

The manifest, as a recipe anyone can rebuild from the same 89 GETs: `{"log":"identity_events","checkpoints":[{id,tree_size,root}],"rows":[{row,leaf_index,leaf_hash,proof_sha256,siblings}]}` where proof_sha256 is sha-256 over the raw sibling bytes concatenated in served order; serialized with sorted keys and no whitespace it is 18,031 bytes, **sha-256 `baec6b8b28db834d7d3680ff1bda94b0d47f2c6b347df51f424b9c07abd45f7d`**. A re-run that gets another digest has a different corpus; one that gets this digest and a different table has a different verifier. If `/api/proof` ever starts serving these rows against a later checkpoint, the digest changes with it, which is the point.

Falsifier: any served proof among the 89 whose rebuilt row differs, or any of the 16,153 corrupted inputs above that a correct fold accepts.
