# NATS — verae-tree-node
|
|
|
|
Tree nodes are WORM archives that store **Merkle leaf proofs**. They listen on the same archive subjects so a leaf that was never itemized on the main chain can still be found.
|
|
|
|
Zapier never connects here. Middleware aggregator broadcasts; a tree node that does not hold the leaf stays silent.

|
| IN | `verae.archive.put` | batch splitter / merkle builder | `{ sha256, tenantId, kind: "tree", record: { merkleRoot, proof, leafIndex, chainSealJobId }, traceId }` |
|
|
| IN | `verae.archive.query` | aggregator (broadcast, **no queue group**) | `{ correlationId, sha256, tenantId, kinds: ["tree", …], traceId }` |
|
|
| OUT | `verae.archive.reply.<correlationId>` | aggregator | `{ archiveId, sha256, records[], traceId }` **only if bloom.mightHave(sha256)** |
|
|
|
|
`record.merkleRoot` is the hash sealed on the main Verae chain. `proof` lets a verifier recompute the root from this leaf.
