Billing implements reserve -> commit -> refund against bl_quota and bl_ledger with row-level locking and idempotency keys; the refund commits on its own transaction so a failed request cannot silently keep a user's quota. Task implements the unified task centre over the state machine. Identity issues and resolves users. Remaining domains are placeholders whose READMEs state what belongs there and what must not.

# `packages/memory/` — 记忆系统（占位）
|
||
|
||
架构 §8.4。与 `packages/profile` 配合：`profile` 管表，这里管策略。
|
||
|
||
## 读（注入）
|
||
|
||
```
|
||
get_memory_snapshot(user_id, budget_tokens)
|
||
→ 优先级：L0 身份 > L1 画像 > L2 显式偏好 > L5 衣橱 > L3 事件
|
||
→ 过滤 status=active 且 confidence >= 阈值
|
||
→ 裁剪到预算内（≤ 500 token，FR-MEM-04）→ 缓存（hash 变更才重建）
|
||
```
|
||
|
||
## 写
|
||
|
||
| 来源 | 置信度 | 行为 |
|
||
| --- | --- | --- |
|
||
| 显式（用户明确说的） | 0.95 | 立即生效，回执告知「已记住」 |
|
||
| 报告产出 | 诊断置信度 | 写 L1 |
|
||
| 行为推断（隐式） | 累积证据 | 达阈值生成 `pending_confirm`，确认后才 active |
|
||
|
||
## 铁律
|
||
|
||
**用户在「我的记忆」页面的编辑拥有最高优先级，且不可被自动覆盖**
|
||
（FR-MEM-05/07）。所有变更写 `pf_memory_event` 留痕。
