# CLVM / Puzzle Execution Context Available

Deep context for this subsystem exists at `.cursor/context/clvm-execution.md`.
Read it before exploring code — it documents the three CLVM execution paths
(mempool, block validation, block building), resource limits (cost, atoms, pairs),
canonical serialization, AGG_SIG replay protection, and `MEMPOOL_MODE` flag
behavior. Condition opcode byte values are owned by `chia/types/condition_opcodes.py`;
see `.cursor/context/types.md` for that ABI invariant.
