Implementation of LP-0013: mint authority model for the LEZ Token program.

Repository: https://github.com/bristinWild/logos-execution-zone (branch: main)

What's implemented:

  • lez-authority crate — agnostic AuthoritySlot library (RFP-001 cross-reference)
  • mint_authority: Option<[u8; 32]> field on TokenDefinition::Fungible
  • NewFungibleDefinitionWithAuthority instruction — create token with authority from day one
  • Mint instruction updated — authority-gated, deterministic rejection when revoked
  • SetAuthority instruction — atomic rotation and permanent revocation
  • Wallet SDK facade methods: send_set_authority, send_new_definition_with_authority
  • 2 integration tests against live sequencer
  • 50 unit tests (42 token_program + 8 authority scenarios + 7 lez-authority)
  • CI green: https://github.com/bristinWild/logos-execution-zone/actions
  • README: docs/LP-0013-README.md
  • Demo script: scripts/demo-full-flow.sh
  • Example scripts: scripts/examples/fixed_supply_token.sh, scripts/examples/variable_supply_token.sh

Pending: CU cost measurement on devnet and narrated video demo (will update solution doc).
