Solution: LP-0013 — Token program authorities

Submitted by: edenbd1

Summary

This solution adds a rotatable mint authority model to the LEZ Token program, implemented as four additive instruction variants on top of the existing token surface. Built around lez-approval — a new agnostic single-admin approval crate fulfilling RFP-001.

Repository

• Repo: https://github.com/edenbd1/logos-execution-zone
• Branch: lp-0013-token-authorities
• Commit: d59379e

What's implemented

• lez-approval crate — RFP-001 agnostic approval library (Authority, ApprovalError, gate/rotate/revoke)
• NewFungibleDefinitionWithAuthority — create token with mint authority
• MintWithAuthority — authority-gated minting with Unauthorized/Renounced panic errors
• RotateAuthority — atomic authority rotation
• RevokeAuthority — permanent terminal revocation
• Wallet SDK facade + CLI subcommands
• Two example integrations (fixed-supply, variable-supply)
• Hand-authored canonical IDL (artifacts/token.idl.json)
• 57 unit tests (13 lez-approval + 44 token_program) + 5 integration test cases
• demo.sh — end-to-end lifecycle demo against standalone LEZ sequencer
• Architecture docs (docs/LP-0013-AUTHORITY.md)

Design highlights

• Additive, not breaking: New FungibleWithAuthority variant of TokenDefinition — existing Fungible definitions and all original instructions untouched
• Terminal revocation: Authority::renounced() is a permanent sentinel (None) that cannot be reversed — provably enforced by the RISC0 guest
• Reusable RFP-001 library: lez-approval depends only on nssa_core::account::AccountId, usable by any LEZ program

Pending: Narrated video walkthrough and CU cycle cost measurement.
