梦境

梦境机制

Nightly creative narratives generated after light sleep; not factual memory. Persisted as a content_block with semantic component dream, parented to the agent world’s dated diary_entry.

概述

梦境是数字生命记忆巩固的想象性对应物。它不提取事实、不更新语义记忆库——而是根据当日的情绪基调与随机情景片段，生成超现实的第一人称叙事。

触发

Condition	Result
No limbic brick with `intensity > 0.5` in the day’s creation window	Skip (`no_strong_emotion`)
Dream block already exists for that day’s diary	Skip (`already_dreamed`)
At least one strong limbic anchor produced that day	Generate dream

触发纯由情绪驱动（无随机掷骰）。不要求 conversation 活动；情景片段可为空。

输入

Emotional tone — top 3 limbic content_blocks whose created_at falls in [conversation day 00:00 CST, next day 06:00 CST) where intensity > 0.5.
Episodic fragments — random sample of user/assistant messages from the day’s sessions, capped ~4k chars.

须先完成浅睡第 2 阶段，以确保感性锚点已写入。

输出

Ensure agent default private world diary for CST dream_day (create empty shell if missing).
Insert content_block (block_type: text) with components content_block + dream.
仅追加；创建后内容不更新。
Does not create notification inbox entries.

Legacy dream_memory / dream_entry rows are backfilled and removed in Drizzle migration 20260717180000_memory_bricks_to_diary.

编排

Sleep-cycle DAG node dream (unchanged topology):

light-sleep
  ├─► deep-sleep ──► memory-ref-sync
  ├─► dream        (parallel)
  └─► self-layer-refresh

工具与 UI

Surface	Purpose
`diary_get` / `content_block_list` (`component=dream`)	Read dream narrative
Shell `/diary`	Browse dream blocks labeled「梦境」（只读）

No independent /dream Shell module or dream ToolSet.

设计说明

梦境不会注入系统提示或常驻记忆。
准确性明确不是目标；联想与隐喻才是。
