PUT/signers/{id}●Submit a new version of a signer.

The request must include the current record hash in data.parent to prevent conflicts from concurrent updates. If the parent hash does not match the record's current hash, the request is rejected with a 422 error.

Broadcasts the signer-updated signal. Use effects to subscribe.

Add signer proof POST

Appends a signed proof to the record. The proof must be signed against the record's current hash. Use proofs to change status, update labels, or record custom data — see [About Proofs](/ledger/structuring-data/about-proofs) for details. Returns the updated record with the new proof in `meta.proofs`. Broadcasts the `signer-proofs-added` signal. Use [effects](/ledger/reference/api/effect) to subscribe.
