Description
🧐 Motivation
The core is deliberately role-free — _mint / _mintNote are ungated — so every deployment would otherwise re-implement the same single-issuer gate.
📝 Details
contracts/src/token/extensions/ConfidentialNoteFungibleTokenIssuer.compact
- Binds one ISSUER role:
_issuerPk = Hf(issuerSecret); the issuer is whoever proves the secret in-circuit via witness, so the identity never appears on chain. _assertIssueris the gate the composing contract puts in front of mint.- Self-rotation: prove the current secret, bind the new key.
- Imports no token module; the consumer wires it.
Landed in #679 (draft).

Research direction
Start with contracts/src/token/extensions/ConfidentialNoteFungibleTokenIssuer.compact and review the draft work referenced in #679. Confirm the extension defines the single issuer binding, issuer assertion, and self-rotation described here, without importing a token module; done means the composing contract can wire it in front of mint.
