#### 搜索内存
在内存存储中执行带有加权L0/L1/L2评分的语义向量搜索。
```sh
-cortex-mem-cli --config config.toml --tenant acme search "用户的爱好是什么？" --thread thread-123 --limit 10
+cortex-mem --config config.toml --tenant acme search "用户的爱好是什么？" --thread thread-123 --limit 10
```
- `query`：搜索的自然语言查询。
- `--thread `：按线程ID过滤内存。
-- `--limit `：最大结果数。默认：10
-- `--min-score `：最小相关性分数（0.0-1.0）。默认：0.3
+- `--limit ` / `-n`：最大结果数。默认：10
+- `--min-score ` / `-s`：最小相关性分数（0.0-1.0）。默认：0.4
- `--scope `：搜索范围："session"、"user"或"agent"。默认："session"
#### 列出内存
从特定URI路径检索内存列表。
```sh
-cortex-mem-cli --config config.toml --tenant acme list --uri "cortex://session" --include-abstracts
+cortex-mem --config config.toml --tenant acme list --uri "cortex://session" --include-abstracts
```
-- `--uri `：要列出的URI路径（例如，"cortex://session"或"cortex://user/preferences"）。
+- `--uri ` / `-u`：要列出的URI路径（例如，"cortex://session"或"cortex://user/preferences"）。默认：`cortex://session`
- `--include-abstracts`：在结果中包含L0摘要。
#### 获取特定内存
按其URI检索特定内存。
```sh
-cortex-mem-cli --config config.toml --tenant acme get "cortex://session/thread-123/memory-456.md"
+cortex-mem --config config.toml --tenant acme get "cortex://session/thread-123/memory-456.md"
```
- `uri`：内存URI。
-- `--abstract-only`：显示L0摘要而不是完整内容。
+- `--abstract-only` / `-a`：显示L0摘要而不是完整内容。
+- `--overview` / `-o`：显示L1概览而不是完整内容。
#### 删除内存

```sh
-cortex-mem-cli --config config.toml --tenant acme delete "cortex://session/thread-123/memory-456.md"

+cortex-mem session close customer-support

+This is the key command for finalizing a conversation — it runs the full processing pipeline:
+1. **Memory Extraction**: LLM analyzes the conversation and extracts structured facts, decisions, and entities.
+2. **Layer Generation**: L0 (abstract) and L1 (overview) files are generated or updated.
+3. **Vector Indexing**: All layers are embedded and indexed in Qdrant for future semantic search.

+## ⚡ Incremental Update System
+
+Introduced an event-driven incremental update pipeline that keeps memory layers in sync efficiently:
+
+- **`MemoryEventCoordinator`**: Central hub that receives `MemoryEvent`s (create/update/delete) and orchestrates downstream processing.
+- **`IncrementalMemoryUpdater`**: Computes content diffs to only re-process changed memories, skipping unchanged content.
+- **`CascadeLayerUpdater`**: When a memory changes, cascades L0/L1 layer updates up the directory tree. Uses content hash check (Phase 1) and LLM result cache (Phase 3) to minimize redundant work.
+- **`LayerUpdateDebouncer`**: Batches rapid successive updates to the same directory (Phase 2), reducing LLM calls by 70-90%.
+- **`LlmResultCache`**: LRU + TTL cache for generated L0/L1 content. Reduces LLM API costs by 50-75% for repeated content.
+- **`VectorSyncManager`**: Keeps the Qdrant vector store synchronized with filesystem changes.
+
+## 🧹 Memory Cleanup (Forgetting Mechanism)
+
+The `MemoryCleanupService` which implements the Ebbinghaus forgetting curve:
+
+- Periodically scans the memory index and calculates **memory strength** based on recency and access frequency.
+- Memories with strength below `archive_threshold` (default: 0.1) are **archived** (marked but not deleted).
+- Archived memories with strength below `delete_threshold` (default: 0.02) are **permanently deleted**.
+- Prevents unbounded storage growth in long-running AI agents.

+
+1. **Language Consistency** (MANDATORY):
+ - Extract memories in the SAME language as the conversation
+ - If conversation is in Chinese (中文) → memories MUST be in Chinese
+ - If conversation is in English → memories in English
+ - If mixed language → use the dominant language (>60% of content)
+ - **DO NOT translate** the conversation content into another language
+
+2. **Preserve Technical Terms** (MANDATORY):
+ - Keep technical terminology unchanged in their original language
+ - Programming languages: Rust, Python, TypeScript, JavaScript, Go
+ - Frameworks: Cortex Memory, Rig, React, Vue
+ - Personality types: INTJ, ENTJ, MBTI, DISC
+ - Proper nouns: names, companies, projects
+ - Acronyms: LLM, AI, ML, API, HTTP, REST
+
+3. **Examples**:
+ ✅ CORRECT (Chinese conversation):
+ - "Cortex Memory 是基于 Rust 的长期记忆系统"
+ - "用户喜欢吃牛肉汉堡，搭配酸黄瓜、芝士和可乐"
+
+ ❌ WRONG (Chinese conversation, should NOT translate to English):
+ - "User likes beef burgers with pickles, cheese, and coke"
