_get_client_cache_key把运行中的事件循环对象作为缓存键的一部分，client_instance_cache是普通Dict，因此每个键都强引用一个AbstractEventLoop。条目只有在clear_client_instance_cache、按client_type清理或配置重载时才被移除。若进程反复创建短生命周期事件循环（例如工作线程内asyncio.run），缓存会按循环数量单调增长，并让已关闭的循环与其客户端常驻内存。这与本 PR 控制内存增长的目标相反。建议在获取实例时顺带清理键中循环已

In `@src/A_memorix/core/embedding/manager.py`:
- Around line 305-317: Update load_cache() to call _prune_embedding_cache()
after replacing/restoring _embedding_cache, while holding self._cache_lock, so
disk caches exceeding MAX_EMBEDDING_CACHE_SIZE are immediately trimmed.
In `@src/A_memorix/core/utils/web_import_manager.py`:
- Around line 4512-4537: Update shutdown() to iterate over a snapshot such as
list(self._tasks.values()) before invoking _mark_task_cancelled_locked, so
pruning mutations to self._tasks cannot invalidate the active iteration.
Preserve the existing cancellation and cleanup sequence.
In `@src/A_memorix/scripts/convert_lpmm.py`:
- Around line 195-203: The _load_plugin_config() flow must distinguish a missing
configuration file from an unreadable or invalid existing file: return an empty
configuration only when the file is absent, but propagate the parse/read failure
or mark the fingerprint unusable so run() cannot publish
vectors/dual_ready.json. Ensure _load_embedding_fingerprint() and run() prevent
the ready manifest on configuration failure, and add regression coverage for
invalid TOML plus matching manifest/runtime fingerprints with a valid custom
embedding configuration.
In `@src/chat/heart_flow/heartflow_message_processor.py`:
- Around line 54-61: 在消息处理流程中，将 MessageUtils.store_message_to_db_async(message)
移到 borrow_chat(message.session_id) 上下文之前，确保运行时借用失败时消息仍完成持久化；仅在入库成功后借用运行时并调用
chat.register_message(message)。更新 heartflow_message_processor 的异常日志，包含
message.session_id、明确操作上下文及完整堆栈信息，避免继续使用缺少上下文的“出现错误”日志。
In `@src/chat/message_receive/chat_manager.py`:
- Around line 271-277: 将 evict_inactive_sessions 调用移入 save_all_sessions 成功后的
else 分支，确保保存失败或抛出异常时不会淘汰内存会话；保留现有淘汰数量日志和异常处理行为。
- Around line 207-210: Synchronize release_session with the
regularly_save_sessions/save_all_sessions path using the existing shared locking
mechanism or a deletion-marker set. Ensure _save_session skips session IDs
marked as deleted, and update release_session to apply the marker atomically
with removing entries from sessions and last_messages so a concurrent save
cannot recreate a deleted ChatSession.
In `@src/llm_models/model_client/openai_client.py`:
- Around line 1245-1248: Update the cleanup in the finally block around
accumulator.close and resp_stream.close so exceptions from awaiting
resp_stream.close are caught and logged without replacing an already-propagating
ReqAbortException or parsing exception; preserve the existing asynchronous close
behavior and accumulator cleanup.
In `@src/services/memory_flow_service.py`:
- Around line 519-521: Update the existing-state flow around
_prune_stale_states() so stale states are also cleaned during reuse of existing
sessions. Schedule pruning at a fixed interval rather than traversing _states on
every message, while preserving the current last_accessed_at update and
new-state behavior.
In `@src/webui/core/rate_limiter.py`:
- Around line 67-76: Update the rate-limiter cleanup around _requests and
record_failed_attempt so authentication-failure keys remain tracked while any
record is still within the active window, even when MAX_TRACKED_REQUEST_KEYS is
exceeded. Use separate storage for auth-failure records or exclude active auth
keys from FIFO eviction, while preserving cleanup of expired records and
unrelated request keys.
In `@src/webui/routers/data_transfer.py`:
- Around line 171-175: Update _new_job to enforce the maximum transfer-job
capacity after _evict_stale_jobs runs: if the active _jobs count still reaches
the limit, reject creation with a clear capacity error instead of inserting
another _TransferJob or creating its temporary resources. Preserve normal job
creation when eviction leaves capacity available.
In `@src/webui/routers/plugin/management.py`:
- Around line 512-516: 更新使用 get_plugin_candidate_paths(manifest_plugin_id)
的安装目录冲突检查，同时验证新格式和旧格式目录；任一候选目录已存在时都应拒绝安装，避免同一插件 ID
出现多个安装目录，并仅在两个目录均不存在时执行现有的移动逻辑。

同步 release_session 与后台保存。
regularly_save_sessions 会在线程中执行 save_all_sessions，但 release_session 会并发修改 self.sessions。聊天删除流程在数据库事务提交后才调用此方法。保存线程如果在此窗口持有旧会话，就可能在删除后通过 _save_session 再次插入 ChatSession。删除接口会返回成功，但聊天流会重新出现。
使用共享锁或删除标记覆盖保存和释放路径。保存时必须跳过已删除的 session_id。

在已有状态路径中也定期清理过期状态。
_prune_stale_states() 只在创建新状态后调用。
如果服务持续处理同一个已有会话，旧会话状态即使超过七天也不会被删除。_states 会继续保留历史状态。
在 if/else 之后按固定时间间隔执行清理。不要在每条消息上无条件遍历全部状态。

为导入结果增加可恢复的持久化状态。
当 plugin_instance 未提供 ingest_text 时，_execute_import() 会先写入段落、实体和关系。Line 708-713 随后调用 store.save()，但直到保存完成后才调用 upsert_external_memory_ref()。如果保存失败，重试无法通过 _existing_summary_result() 去重。重试还会再次累加实体计数，并可能因 LLM 返回不同摘要而创建新的段落及关系关联。请让保存失败可恢复，或让重试只执行未完成的持久化步骤。

为 metadata-only 实体写入增加向量回填。
当 allow_metadata_only_write=True 且 _ensure_entity_vectors() 写入失败时，_execute_import() 只记录 warning 并继续导入。现有回填队列只处理段落向量，因此实体 metadata 会存在，但 graph vector 缺失，后续实体向量检索无法命中。

876-890: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift实体向量失败时避免提交部分实体。
metadata_store.transaction()和graph_store.batch_update()在_ensure_entity_vectors()调用前结束。metadata-only 模式关闭时，如果实体向量写入失败，实体 metadata 和图节点已经提交，但导入仍返回失败。由于 external ID 索引尚未写入，下一次重试可能重复创建实体和关系。请在提交前建立可恢复的实体向量状态，或让重试只执行未完成的实体向量步骤。

external_id幂等引用。
upsert_external_memory_ref()会立即提交引用；_existing_summary_result()只检查段落记录，不检查向量库或图存储。如果后续save()失败，重试会返回“总结已存在”并跳过未完成的持久化步骤，导致数据不完整。请让引用仅在所有持久化步骤成功后提交，或增加 pending/completed 状态。请增加保存失败后的重试回归测试。

1. 心流生命周期与锁优化
WeakValueDictionary管理会话锁与运行时实例，防止死会话锁常驻内存。borrow_chat在协程被取消（CancelledError）路径下必定释放使用租约，杜绝死锁与租约悬挂。2. 全仓内存泄露与资源控制
openai_client/gemini_client在外部打断或解析异常时未显式关闭底层 stream（SSE 连接滞留）的问题。maisaka/reply_effect：终态且无活跃引用的回复效果记录在评审完成后自动移除。maisaka/runtime：心流history_loop改为有界deque(maxlen=200)。chat_manager：增加 24h 不活跃会话与过期消息的定期内存淘汰。A_memorix检索调优：增加已完成任务记录上限（50 条）与修剪机制；画像刷新循环自动剔除过期人物时间戳。embedding向量缓存、llm_cache_stats统计键、rate_limiterIP 表均增加容量上限与淘汰机制。rpc_server/rpc_client在调用方被取消时 pending 请求表条目残留问题。emoji_manager启动加载增加 SQL 层过滤，避免全表物化聊天图片；注册成功后及时释放常驻的image_bytes。limit=0穿透触发全库物化。runner_rpc_debug.jsonl增加单代 16MB 自动轮转（保留一代.1）。replyer_action_*.json每次写入后自动维护，保留最近 200 个文件。memory.py预取最新消息改为按会话最大时间戳子查询；时间界探测改为有界采样。3. 测试用例与兼容性修复
test_startup_bindings、test_jargon_routes、test_memory_routes、test_model_routes、test_plugin_management_routes、test_lpmm_convert等存量测试断言与 mock 桩。ruff check0 警告 0 报错。其他信息
src/A_memorix的改动均为最小化防御性补丁（向量缓存上限、调优任务修剪与时间戳清理），严格遵守 A_memorix 修改策略。Summary by CodeRabbit
