Blind spot (现状盲点)
[`docs/specs/continuum-memory.md`](../specs/continuum-memory.md) 已经要求 memory owner 支持 checkpoint / rollback,并且 reflection durable apply 是 bounded 的。但只要系统允许 promotion、decay、retrieval-induced reinforcement、belief writeback、derived index 重排,就一定存在**memory drift** 风险:错误事实被反复强化、过期记忆持续 dominate retrieval、某个 owner snapshot 在 session-post consolidation 后反复震荡。CMA 明确把 Memory Drift 列为失败模式,并建议记录 provenance、reinforcement history、anomaly scores;这与 VZ R10 ModificationGate 天然对齐。 但 CMA 的建议偏日志层,太浅。VZ 不应只统计"某个 fragment 被 reinforce 次数过多",而要把 drift 定义在 **PE 没下降 + retrieval dominance 上升 + owner snapshot stability 变差** 的交叉处。
Adoptable suggestions (可落地动作)
- 1.在 [`docs/specs/credit-and-self-modification.md`](../specs/credit-and-self-modification.md) 增加 "Memory Drift Telemetry" 小节,作为 ModificationGate 的 read-only 输入,不直接作为 reward。PROPOSED
Not a runnable A/B candidate — evaluated by the path above, not ablation.
- 2.定义最小 drift signals: - `reinforcement_without_pe_drop`:某记忆被持续强化,但相关 PE 没有下降; - `retrieval_dominance_spike`:少数 fragments 在多场景中过度 dominate recall; - `outdated_fact_reactivation`:已被更新/废弃的事实持续被激活; - `owner_snapshot_oscillation`:belief / commitment / relationship_state 等 owner 快照在 slow loop 后反复震荡; - `rollback_or_shadow_abort_rate`:memory 相关改动触发 rollback / SHADOW abort 的频率升高。PROPOSED
Not a runnable A/B candidate — evaluated by the path above, not ablation.
- 3.第一阶段只做 anomaly report,不自动关门;第二阶段再决定是否接入 ModificationGate 阈值。PROPOSED
Not a runnable A/B candidate — evaluated by the path above, not ablation.
- 4.若推进 CMA-1,则 CMA-3 必须先做或并行做;否则 spreading activation 的反馈回路没有 drift 护栏。PROPOSED

Expected benefit (预期收益)
- 把 memory drift 从"上线后用户感觉不对"提前到 telemetry 层发现。 - 给 CMA-1 / DM-6 / reflection writeback 这类会改变 memory dynamics 的改动加安全垫。 - 与 OA-4 VZ-Audit Agent、OA-3 FramingAwarenessCheck 共同构成 R10 的三层防线:语义 framing、防御审计、记忆漂移。

Retrieval-induced updates can slowly distort facts if feedback loops reinforce incorrect memories. Instrumentation should log provenance, reinforcement history, and anomaly scores so stewards can rewind or dampen runaway updates. - 关键观点:active memory 的收益必然伴随 drift 风险。VZ 可以借鉴 CMA 的 drift logging,但必须升级为 PE-aware / owner-snapshot-aware 的 telemetry,而不是简单 reinforcement counter。 ---
