+### Built-in vs External Plugins
+
+| Dimension | Built-in Plugin | External Plugin |
+|-----------|----------------|-----------------|
+| Registration | `init()` calls `plugin.RegisterFactory(name, factory)` | Implements `NewPluginFactory(name, config) (sdk.Plugin, error)` entry function |
+| Compilation | Compiled into `homed` binary, no separate build | Compiled via `plugindev build` to `.so`/`.dll` (`-buildmode=c-shared`), loaded via C ABI bridge |
+| Distribution | Bundled with kernel, not independently installable | `.hmap` package (ZIP archive), installed via WebUI or pluginmgr API |
+| Metadata | `plugin.RegisterPluginMeta()` for display name | `plugin.json` manifest file (name, version, entry, platforms, etc.) |
+| Plugin directory | No separate directory, compiled into binary | `plugins/<name>/` independent directory with `plugin.json` + binary |
+| SDK permissions | Full PluginSDK (SocialAPI read/write, Publish events) | Restricted SDK (SocialAPI read-only, Subscribe-only events) |
+| Lifecycle | Starts/stops with kernel, no individual hot-reload | Independent Start/Stop, supports hot-reload (ReloadOne) and enable/disable |
+| Crash recovery | No independent recovery | Supports `SetAutoRestart(true)` for automatic crash restart |
+
+Common ground:
+- Built-in `RegisterFactory` and external `NewPluginFactory` share the same `NativeFactory` type signature
+- `Registry.Load()` handles both uniformly: checks factory table first (built-in), falls back to dynamic loading (external)
+- Both use the same `Plugin` interface and `PluginSDK`; tool registration, stage hooks, and output channel APIs are identical
+- Both share the same tool registry (`StageHost`); LLM invocations treat them identically

 The significance lies in clear responsibility boundaries: the kernel focuses on orchestration and memory management, while plugins handle IO implementation — the two are not coupled.
 
 **Three-Layer Memory Architecture** — Manages information retention across long agent runtimes through a tiered storage strategy:
-- **Context Layer**: In-memory local word embedding scored event window (jieba + TF-IDF + PMI → CosineSimilarity), maintains recent context in real-time, low-relevance events automatically sink to the next layer
+- **Context Layer**: In-memory pretrained word embedding scored event window (StaticEmbedder word vectors → CosineSimilarity, TF-IDF fallback), maintains recent context in real-time, low-relevance events automatically sink to the next layer
 - **Document Layer**: JSON files + TF-IDF vector-indexed temporary memory, supports explicit submission and implicit archival, cold data distills to Graph
 - **Graph Layer**: SQLite graph database, persists entities and relations, BFS traversal recall, distillation pipeline extracts triples from conversations
