+- 🧩 一条复合消息会先自动拆成多个子任务
 - 🔀 同一会话内：无资源冲突的子任务可并发执行
 - 🔒 同一会话内：有资源冲突的子任务自动串行（避免互相踩）
 - 🏷️ 默认会自动推断 `resource_keys`，无需手动填写

+## 记忆与 EKG 增强（新）🧠
+
+- 📚 每个子任务执行前会自动检索相关记忆（`memory_search`）
+- 🚨 会结合 EKG 与任务审计识别“重复错误签名”风险
+- ⏱️ 高风险任务会自动附带重试退避建议，减少重复踩坑

+## Telegram 流式渲染优化（新）💬
+
+- 🧷 只在语法安全断点刷新流式内容（减少格式抖动）
+- ✅ 结束时做一次最终收敛渲染，保证排版稳定

 ## Concurrency Scheduling (New) ⚙️
 
-- 🧩 A composite message is auto-split into sub-tasks (configurable max)
+- 🧩 A composite message is automatically split into sub-tasks
 - 🔀 Within the same session: non-conflicting tasks run in parallel
 - 🔒 Within the same session: conflicting tasks run serially (to avoid collisions)
 - 🏷️ `resource_keys` are inferred automatically by default (no manual input needed)

+## Memory + EKG Enhancements (New) 🧠
+
+- 📚 Before each sub-task runs, related memory is fetched via `memory_search`
+- 🚨 EKG + task-audit are used to detect repeated error-signature risks
+- ⏱️ High-risk tasks include retry-backoff hints to reduce repeated failures

+
+## Telegram Streaming Rendering (New) 💬
+
+- 🧷 Stream flushes happen at syntax-safe boundaries to reduce formatting jitter
+- ✅ A final convergence render is applied when streaming ends for stable layout
