- Add integration test `token_rotate_authority_then_new_authority_can_mint`: create with self-authority, rotate to external key, verify new authority mints as rest account, verify old authority is rejected (RFP-001 end-to-end) - Fix README error table: 'must sign' -> 'must authorize' (matches mint.rs:36) - Fix guest doc comments for mint/set_authority to describe the 0-or-1 external authority model correctly - Fix example scripts: new-fungible-definition-with-authority -> new-fungible-definition, --initial-supply -> --total-supply (align to token-idl.json and demo-full-flow.sh)

# LP-0013 Example: Variable Supply Token with Authority Rotation
|
|
#
|
|
# Demonstrates, against a real LEZ sequencer via spel:
|
|
# - creating a fungible token with a mint authority
|
|
# - minting additional supply (authority-gated)
|
|
# - rotating the mint authority to a new key
|
|
#
|
|
# The guarantee that the OLD authority can no longer mint after rotation —
|
|
# and that only the current authority's signer is accepted — is enforced by
|
|
# lez-authority's AuthoritySlot and covered by:
|
|
# - token_program unit tests: set_authority_rotate_then_old_cannot_mint,
|
|
# mint_with_wrong_signer_fails, set_authority_wrong_signer_fails
|
|
# - integration test: token_set_authority_revoke
|
|
# Run them with: RISC0_DEV_MODE=0 cargo test -p token_program -p lez-authority --lib
|
|
#
|
|
# Usage (from inside an lgs scaffold project dir):
|
|
# RISC0_DEV_MODE=0 bash <path-to-lez-programs>/scripts/examples/variable_supply_token.sh
