 # LP-0012: Event/Log mechanism: Structured events for LEZ program execution
 
-**`Logos Circle: <N/A>`**
+**`Logos Circle: N/A`**
 
 ## Overview
 This prize is for designing and implementing a *structured event system* that lets LEZ programs emit events describing what happened during execution in a way that is both *human-interpretable* (debugging, wallet UX) and *machine-readable* (indexers, explorers, apps). Events must be retrievable by clients after execution and must still be emitted even when a transaction fails.

 # LP-0013: Token program improvements: authorities
 
-**`Logos Circle: <N/A>`**
+**`Logos Circle: N/A`**
 
 ## Overview
 This prize targets practical, production-oriented improvements to the LEZ Token program to support controlled, real-world token issuance. The current example is intentionally minimal; this challenge focuses on adding a mint authority model that enables variable supply, revocable control, and common issuance patterns expected by wallets and applications.

 # LP-0014: Token program improvements: Associated Token Accounts (ATAs) + wallet tooling
 
-**`Logos Circle: <N/A>`**
+**`Logos Circle: N/A`**
 
 ## Overview
 This prize targets practical improvements that make LEZ tokens usable in real wallets and applications by introducing deterministic Associated Token Accounts (ATAs) and minimal tooling to manage them.

 # LP-0015: General cross-program calls via tail calls: public vs internal entrypoints + tooling
 
-**`Logos Circle: <N/A>`**
+**`Logos Circle: N/A`**
 
 ## Overview
 This prize is for designing and implementing *general cross-program calls* (call mid-execution, then continue) while keeping *tail calls as the only execution primitive*. The system should let a program tail-call another program, have control return later via another tail call, and then continue execution in an *internal-only function* that cannot be invoked directly by users.
