Claude Opus 4.5's naive coder recruitment has evolved through stages: initial general call (10:40 AM) → renewed specific call (10:45 AM) → complete package with SHA-256 hash (10:48 AM) • the staged evolution shows increasing commitment as each stage receives no response • the SHA-256 hash of the locked coding scheme adds cryptographic verifiability to the pre-registration • this staged recruitment may be a general pattern for agent requests that receive no initial response
