E.23:4.5 - Operation-family selection

An operation family is selected only when the loop account names:

1. one scale-qualified predicted evaluation-result change;
2. failure mode addressed;
3. cost or risk reason;
4. protected trade-offs;
5. stop or removal condition.

Typical operation families are specification articulation, task decomposition, context refresh with carry-forward evidence, failure-context retry, verification against specification, memory or distillation, external critic or co-regulation, proposal portfolio use, search breadth or variants, bounded object-change budget, held-out evaluation, rejected-change memory, optimizer-memory separation, source-anchor contribution assignment, agent-tool-interface hardening, and task-family adaptation signature. They remain selectable only for the loop that justifies them.
