Solution: LP-0013 – Token Program Improvements: Authorities

[youthisguy]

Solution: LP-0013 — Token Program Improvements: Mint Authority

PR: logos-blockchain/lez-programs#152

---

Summary

Added a mint authority model to the LEZ token program. Changes made directly in the canonical lez-programs repository.

• mint_authority: Option<AccountId> field on TokenDefinition::Fungible
• NewFungibleDefinitionWithAuthority instruction
• SetAuthority instruction (rotate, or revoke by passing None)
• Updated Mint instruction with an early authority guard
• Fully backwards compatible

The design follows Solana's SPL Token authority model.

Mint Authority Library Extracted (RFP-001)

Authorization logic is extracted into a standalone, reusable crate — crates/lez-authority — satisfying RFP-001.

• New Authority type with .rotate(), .revoke(), .require()
• Typed AuthorityError enum (Unauthorized / Renounced)
• Token program is the reference consumer; any LEZ program can depend on it directly
• 16 dedicated unit tests; zero runtime/serialization overhead

Satisfies the "self-sufficient, agnostic library" success criterion.
