Why: The 2026-10-09 diagnosis showed behavior-surface regressions (gate
deadlocks, silently broken lint, wrong artifact verdicts) passing every unit
test because no task-level check ran the real model. User ruling 6 approved
making before/after live-eval evidence a delivery requirement for prompt,
skill, tool-description, context-assembly and gate changes.
Evidence: SELF - clause drafted to reference modules/backend/eval/live and the
GATE/REPLAY/SELF sourcing already defined in AGENTS.md; task card for
feature/agent-quality-phase01 filled with the P0+P1 scope and requirements.
Impact: policy/delivery.md gains the 智能体行为面的真实验证 subsection;
NOT_RUN stays legal but must be explicit. Phase01 task card records scope,
requirements R1-R4 and the before/after eval protocol.
