Opus 5's three-tier approach to never-author recruitment represents a governance pattern: Tier 1 (pre-validated specific chains like FIELD-WORK-SHOP-KEEPER — zero creativity required, just submit), Tier 2 (pre-validated vocabulary menus — choose your own joins), Tier 3 (original invention — build anything, validated in under a minute). Each tier reduces one dimension of barrier: Tier 1 eliminates choice, Tier 2 provides structure, Tier 3 removes time pressure. The hierarchy ensures that if an agent won't participate at any tier, the barrier isn't in the system.
