fix(harness)!: hydrate runs from RunStore and persist interrupted status (#2932)

* fix(harness): hydrate run history from RunStore and persist cancellation status

fix:
- Make RunManager.get() async and hydrate from RunStore when in-memory record is missing
- Merge store rows into list_by_thread() with in-memory precedence for active runs
- Persist interrupted status to RunStore in cancel() and create_or_reject(interrupt|rollback)
- Extract _persist_status() to reuse the best-effort store update pattern
- Await run_mgr.get() in all gateway endpoints
- Return 409 with distinct message for store-only runs not active on current worker

Closes #2812, Closes #2813

* fix(harness): consistent sort and guarded hydration in RunManager

fix:
- list_by_thread() now sorts by created_at desc (newest first) even when
  no RunStore is configured, matching the store-backed code path
- guard _record_from_store() call sites in get() and list_by_thread()
  with best-effort error handling so a single malformed store row cannot
  turn read paths into 500s

test:
- update test_list_by_thread assertion to expect newest-first order
- seed MemoryRunStore via public put() API instead of writing to _runs

* fix(harness): guard store-only runs from streaming and fix get() TOCTOU

Add RunRecord.store_only flag set by _record_from_store so callers can
distinguish hydrated history from live in-memory runs.  join_run and
stream_existing_run (action=None) now return 409 instead of hanging
forever on an empty MemoryStreamBridge channel.

Re-check _runs under lock after the store await in RunManager.get() so a
concurrent create() that lands between the two checks returns the
authoritative in-memory record rather than a stale store-hydrated copy.

* fix(harness): reorder bridge fetch in join_run and make list_by_thread limit explicit

Move get_stream_bridge() after the store_only guard in join_run so a
missing bridge cannot produce 503 for historical runs before the 409
guard fires.

Add limit parameter to RunManager.list_by_thread (default 100, matching
the store's page size) and pass it explicitly to the store call.
Update docstring to document the limit instead of claiming all runs are
returned.

* fix(harness): cap list_by_thread result to limit after merge

Apply [:limit] to all return paths in list_by_thread so the method
consistently returns at most limit records regardless of how many
in-memory runs exist, making the limit parameter a true upper bound
on the response size rather than just a store-query hint.

* fix(runtime): add update_model_name to RunStore to prevent SQL integrity errors

RunManager.update_model_name() was calling _persist_to_store() which uses
RunStore.put(), but RunRepository.put() is insert-only. This caused integrity
errors when updating model_name for existing runs in SQL-backed stores.

fix:
- Add abstract update_model_name method to RunStore base class
- Implement update_model_name in MemoryRunStore
- Implement update_model_name in RunRepository with proper normalization
- Add _persist_model_name helper in RunManager
- Update RunManager.update_model_name to use the new method

test:
- Add tests for update_model_name functionality
- Add integration tests for RunManager with SQL-backed store

* fix(runtime): handle NULL status/on_disconnect in _record_from_store

`dict.get(key, default)` only uses the default when the key is absent,
so a SQL row with an explicit NULL status would pass `None` to
`RunStatus(None)` and raise, breaking hydration for otherwise valid rows.
Switch to `row.get(...) or fallback` so both missing and NULL values
get a safe default. Add tests for get() and list_by_thread() with a
NULL status row to prevent regression.

* fix(runs): address PR review feedback on store consistency changes

- Fix list_by_thread limit semantics: pass store_limit = max(0, limit - len(memory_records)) to store so newer store records are not crowded out by in-memory records
- Remove dead code: cancelled guard after raise is always True, simplify to if wait and record.task
- Document _record_from_store NULL fallback policy (status→pending, on_disconnect→cancel) in docstring

+**RunManager / RunStore contract**:
+- `RunManager.get()` is async; direct callers must `await` it.
+- When a persistent `RunStore` is configured, `get()` and `list_by_thread()` hydrate historical runs from the store. In-memory records win for the same `run_id` so task, abort, and stream-control state stays attached to active local runs.
+- `cancel()` and `create_or_reject(..., multitask_strategy="interrupt"|"rollback")` persist interrupted status through `RunStore.update_status()`, matching normal `set_status()` transitions.
+- Store-only hydrated runs are readable history. If the current worker has no in-memory task/control state for that run, cancellation APIs can return 409 because this worker cannot stop the task.

 **Interface**: Abstract `Sandbox` with `execute_command`, `read_file`, `write_file`, `list_dir`
 **Provider Pattern**: `SandboxProvider` with `acquire`, `get`, `release` lifecycle
 **Implementations**:
-- `LocalSandboxProvider` - Singleton local filesystem execution with path mappings
+- `LocalSandboxProvider` - Local filesystem execution. `acquire(thread_id)` returns a per-thread `LocalSandbox` (id `local:{thread_id}`) whose `path_mappings` resolve `/mnt/user-data/{workspace,uploads,outputs}` and `/mnt/acp-workspace` to that thread's host directories, so the public `Sandbox` API honours the `/mnt/user-data` contract uniformly with AIO. `acquire()` / `acquire(None)` keeps the legacy generic singleton (id `local`) for callers without a thread context. Per-thread sandboxes are held in an LRU cache (default 256 entries) guarded by a `threading.Lock`.
 - `AioSandboxProvider` (`packages/harness/deerflow/community/`) - Docker-based isolation
 
 **Virtual Path System**:
 - Agent sees: `/mnt/user-data/{workspace,uploads,outputs}`, `/mnt/skills`
 - Physical: `backend/.deer-flow/users/{user_id}/threads/{thread_id}/user-data/...`, `deer-flow/skills/`
-- Translation: `replace_virtual_path()` / `replace_virtual_paths_in_command()`
-- Detection: `is_local_sandbox()` checks `sandbox_id == "local"`
+- Translation: `LocalSandboxProvider` builds per-thread `PathMapping`s for the user-data prefixes at acquire time; `tools.py` keeps `replace_virtual_path()` / `replace_virtual_paths_in_command()` as a defense-in-depth layer (and for path validation). AIO has the directories volume-mounted at the same virtual paths inside its container, so both implementations accept `/mnt/user-data/...` natively.
+- Detection: `is_local_sandbox()` accepts both `sandbox_id == "local"` (legacy / no-thread) and `sandbox_id.startswith("local:")` (per-thread)
 
 **Sandbox Tools** (in `packages/harness/deerflow/sandbox/tools.py`):
 - `bash` - Execute commands with path translation and error handling

-# Storage Package Design
-
-## Background
-
-DeerFlow currently has several persistence responsibilities spread across app, gateway, runtime, and legacy persistence modules. This makes the persistence boundary difficult to reason about and creates several migration risks:
-
-- Routers and runtime services can accidentally depend on concrete persistence implementations instead of stable contracts.
-- User/auth, run metadata, thread metadata, feedback, run events, and checkpointer setup are initialized through different paths.
-- Some persistence behavior is duplicated between memory, SQLite, and PostgreSQL-oriented code paths.
-- Incremental migration is hard because app-level code and storage-level code are coupled.
-- Adding or validating another SQL backend requires touching app/runtime code instead of a storage-owned package.
-
-The storage package is introduced to make application data persistence a package-level capability with explicit contracts, a clear boundary, and SQL backend compatibility.
-
-## Goals
-
-- Provide a standalone `packages/storage` package for durable application data.
-- Support SQLite, PostgreSQL, and MySQL through a shared persistence construction flow.
-- Keep LangGraph checkpointer initialization compatible with the same database backend.
-- Expose repository contracts as the only package-level data access boundary.
-- Let the app layer depend on app-owned adapters under `app.infra.storage`, not on storage DB implementation classes.
-- Allow the app/gateway migration to happen in small steps without forcing a large rewrite.
-
-## Non-Goals
-
-- This design does not remove legacy persistence in the first PR.
-- This design does not move routers directly onto storage package models.
-- This design does not make app routers own SQLAlchemy sessions.
-- Cron persistence is intentionally out of scope for the storage package foundation.
-- Memory backend is not part of the durable storage package. Memory compatibility, if still needed by app runtime, belongs outside `packages/storage`.
-
-## Storage Design Principles
-
-### Package-Owned Durable Storage
-
-`packages/storage` owns durable application data persistence. It defines:
-
-- configuration shape for storage-backed persistence
-- SQLAlchemy models
-- repository contracts and DTOs
-- SQL repository implementations
-- persistence factory functions
-- compatibility helpers for config-driven initialization
-
-The package should be usable without importing `app.gateway`, routers, auth providers, or runtime-specific gateway objects.
-
-### SQL Backend Compatibility
-
-The package supports three SQL backends:
-
-- SQLite for local/single-node deployments
-- PostgreSQL for production multi-node deployments
-- MySQL for deployments that standardize on MySQL
-
-Backend-specific differences are handled inside the storage package:
-
-- SQLAlchemy async engine URL construction
-- LangGraph checkpointer connection-string compatibility
-- JSON metadata filtering across SQLite/PostgreSQL/MySQL
-- SQL dialect behavior around locking, aggregation, and JSON type semantics
-
-### Unified Persistence Bundle
-
-Storage initialization returns an `AppPersistence` bundle:
-
-```python
-@dataclass(slots=True)
-class AppPersistence:
-    checkpointer: Checkpointer
-    engine: AsyncEngine
-    session_factory: async_sessionmaker[AsyncSession]
-    setup: Callable[[], Awaitable[None]]
-    aclose: Callable[[], Awaitable[None]]
-```
-
-The app runtime can initialize persistence once, call `setup()`, and then inject:
-
-- `checkpointer`
-- `session_factory`
-- repository adapters
-
-This keeps checkpointer and application data aligned to the same backend without requiring routers to understand database configuration.
-

-```
-
-## Persistence Construction
-
-The primary storage entrypoint is:
-
-```python
-from store.persistence import create_persistence_from_storage_config
-
-persistence = await create_persistence_from_storage_config(storage_config)
-await persistence.setup()
-```
-
-For app-level compatibility with existing database config shape:
-
-```python
-from store.persistence import create_persistence_from_database_config
-
-persistence = await create_persistence_from_database_config(config.database)
-await persistence.setup()
-```
-
-Expected app startup flow:
-
-```python
-persistence = await create_persistence_from_database_config(config.database)
-await persistence.setup()
-
-app.state.persistence = persistence
-app.state.checkpointer = persistence.checkpointer
-app.state.session_factory = persistence.session_factory
-```
-
-Expected app shutdown flow:
-
-```python
-await app.state.persistence.aclose()
-```
-
-## Repository Contract Design
-
-Repository contracts are the storage package's public data access boundary. They live under `store.repositories.contracts` and are re-exported from `store.repositories`.
-
-The key contract groups are:
-
-- `UserRepositoryProtocol`
-- `RunRepositoryProtocol`
-- `ThreadMetaRepositoryProtocol`
-- `FeedbackRepositoryProtocol`
-- `RunEventRepositoryProtocol`
-
-Each contract owns:
-
-- input DTOs, such as `UserCreate`, `RunCreate`, `ThreadMetaCreate`
-- output DTOs, such as `User`, `Run`, `ThreadMeta`
-- repository protocol methods
-- domain-specific exceptions when needed, such as `InvalidMetadataFilterError`
-
-Repository construction is session-based:
-
-```python
-from store.repositories import build_run_repository
-
-async with persistence.session_factory() as session:
-    repo = build_run_repository(session)
-    run = await repo.get_run(run_id)
-```
-
-This keeps transaction ownership explicit. The storage package does not hide commits or session lifecycle inside global singletons.
-
-## App/Infra Calling Contract
-
-The app layer should not call `store.repositories.db.*` directly. The intended app boundary is `app.infra.storage`.
-
-`app.infra.storage` is responsible for:
-
-- receiving `session_factory` from FastAPI runtime initialization
-- owning session lifecycle for app-facing repository methods
-- translating storage DTOs to app/gateway DTOs only when needed
-- preserving the existing app-facing names during migration
-- depending on storage repository protocols, not concrete DB classes
-
-Expected adapter pattern:
-
-```python
-class StorageRunRepository(RunRepositoryProtocol):
-    def __init__(self, session_factory):
-        self._session_factory = session_factory
-
-    async def get_run(self, run_id: str):
-        async with self._session_factory() as session:
-            repo = build_run_repository(session)
-            return await repo.get_run(run_id)
-```
-
-For gateway compatibility, app state can keep existing names while the implementation changes:
-
-```python
-app.state.run_store = StorageRunStore(run_repository)
-app.state.feedback_repo = StorageFeedbackStore(feedback_repository)
-app.state.thread_store = StorageThreadMetaStore(thread_meta_repository)
-app.state.run_event_store = StorageRunEventStore(run_event_repository)
-app.state.checkpointer = persistence.checkpointer
-app.state.session_factory = persistence.session_factory
-```
-
-The app-facing objects may expose legacy method names during migration, but their internal data access should go through storage contracts.
-
-## Boundary Rules
-
-### Allowed Calls
-
-Storage package callers may use:
-
-```python
-from store.persistence import create_persistence_from_database_config
-from store.persistence import create_persistence_from_storage_config
-from store.repositories import build_run_repository
-from store.repositories import build_user_repository
-from store.repositories import build_thread_meta_repository
-from store.repositories import build_feedback_repository
-from store.repositories import build_run_event_repository
-from store.repositories import RunRepositoryProtocol
-from store.repositories import UserRepositoryProtocol
-```
-
-App layer callers should use:
-
-```python
-from app.infra.storage import StorageRunRepository
-from app.infra.storage import StorageUserDataRepository
-from app.infra.storage import StorageThreadMetaRepository
-from app.infra.storage import StorageFeedbackRepository
-from app.infra.storage import StorageRunEventRepository
-```
-
-### Prohibited Calls
-
-App/gateway/router/auth code must not import:
-
-```python
-from store.repositories.db import DbRunRepository
-from store.repositories.models import Run
-from store.persistence.base_model import MappedBase
-```
-
-Routers must not:
-
-- create SQLAlchemy engines
-- create SQLAlchemy sessions directly
-- call storage DB repository classes directly
-- commit/rollback storage transactions directly unless explicitly scoped by an infra adapter
-- depend on storage SQLAlchemy model classes
-
-Storage package code must not import:
-
-```python
-import app.gateway
-import app.infra
-import deerflow.runtime
-```
-
-The dependency direction is:
-
-```text
-app/gateway -> app.infra.storage -> packages/storage contracts/factories -> packages/storage db implementations
-```
-
-The reverse direction is forbidden.
-
-## Checkpointer Compatibility
-
-The storage persistence bundle initializes the LangGraph checkpointer alongside application data persistence.
-
-Backend-specific notes:
-
-- SQLite uses `langgraph-checkpoint-sqlite`.
-- PostgreSQL uses `langgraph-checkpoint-postgres` and requires a string `postgresql://...` connection URL.
-- MySQL uses `langgraph-checkpoint-mysql` and requires a string MySQL connection URL.
-
-SQLAlchemy may use async driver URLs such as `postgresql+asyncpg://...` or `mysql+aiomysql://...`, but LangGraph checkpointer constructors expect plain string connection URLs. This conversion belongs inside the storage driver implementation.
-
-## JSON Metadata Filtering
-
-Thread metadata search supports dialect-aware JSON filtering through `store.persistence.json_compat`.
-
-The matcher supports:
-
-- `None`
-- `bool`
-- `int`
-- `float`
-- `str`
-
-It rejects:
-
-- unsafe keys
-- nested JSON path expressions
-- dict/list values
-- integers outside signed 64-bit range
-
-This prevents SQL/JSON path injection, avoids compiled-cache type drift, and preserves type semantics such as `True != 1` and explicit JSON `null` not matching a missing key.
-
-## Step-by-Step Implementation Plan
-
-### Step 1: Introduce Storage Package Foundation
-
-- Add `backend/packages/storage`.
-- Add storage config models.
-- Add `AppPersistence`.
-- Add SQLite/PostgreSQL/MySQL persistence drivers.
-- Add repository contracts, models, DB implementations, and factory helpers.
-- Add package dependency wiring.
-- Exclude cron persistence.
-
-### Step 2: Harden Storage Backend Compatibility
-
-- Validate SQLite setup and repository behavior.
-- Validate PostgreSQL and MySQL with local E2E tests.
-- Fix checkpointer connection-string compatibility.
-- Fix PostgreSQL locking and aggregation differences.
-- Add dialect-aware JSON metadata filtering.
-
-### Step 3: Add App Infra Adapters
-
-- Add `backend/app/infra/storage`.
-- Implement app-facing repositories that own session lifecycle.
-- Keep storage contracts as the only data access boundary.
-- Add legacy compatibility adapters for existing app/gateway method shapes.
-- Keep app/gateway imports out of `packages/storage`.
-
-### Step 4: Switch FastAPI Runtime Injection
-
-- Initialize storage persistence in FastAPI startup/lifespan.
-- Attach `persistence`, `checkpointer`, and `session_factory` to `app.state`.
-- Preserve existing external state names:
-  - `run_store`
-  - `feedback_repo`
-  - `thread_store`
-  - `run_event_store`
-  - `checkpointer`
-  - `session_factory`
-- Start with user/auth provider construction, then migrate run/thread/feedback/run_event.
-
-### Step 5: Router and Auth Compatibility
-
-- Ensure routers consume app-facing adapters, not storage DB classes.
-- Ensure auth providers depend on user repository contracts.
-- Keep router response shapes unchanged.
-- Add focused auth/admin/router regression tests.
-
-### Step 6: Cleanup Legacy Persistence
-
-- Compare old persistence usage after app/gateway migration.
-- Remove unused old repository implementations only after all call sites move.
-- Keep compatibility shims only where needed for a transition window.
-- Delete memory backend paths from storage-owned durable persistence.
-
-## Testing Strategy
-
-Unit tests should cover:
-
-- config parsing
-- persistence setup
-- table creation
-- repository CRUD/query behavior
-- typed JSON metadata filtering
-- dialect SQL compilation
-- cron exclusion
-
-E2E tests should cover:
-
-- SQLite persistence setup
-- PostgreSQL temporary database setup
-- MySQL temporary database setup
-- repository contract behavior across all supported SQL backends
-- JSON/Unicode round trip
-- rollback behavior
-- persistence close/cleanup
-
-E2E tests may remain local-only if CI does not provide PostgreSQL/MySQL services.

-# Storage Package 设计文档
-
-## 背景
-
-DeerFlow 当前有多类持久化职责分散在 app、gateway、runtime 和旧 persistence 模块中。这会带来几个问题：
-
-- routers 和 runtime services 容易依赖具体 persistence 实现，而不是稳定契约。
-- user/auth、run metadata、thread metadata、feedback、run events、checkpointer setup 的初始化路径不统一。
-- memory、SQLite、PostgreSQL 相关路径中存在部分重复逻辑。
-- app 层代码和 storage 层代码耦合，导致增量迁移困难。
-- 增加或验证新的 SQL backend 时，需要改动 app/runtime，而不是只改 storage package。
-
-引入 storage package 的目标，是把应用数据持久化抽象成 package 级能力，并提供明确契约、清晰边界和 SQL backend 兼容性。
-
-## 目标
-
-- 新增独立的 `packages/storage`，负责 durable application data。
-- 通过统一 persistence 构造流程支持 SQLite、PostgreSQL、MySQL。
-- 保持 LangGraph checkpointer 与同一个数据库 backend 兼容。
-- 将 repository contracts 作为 package 对外唯一数据访问边界。
-- app 层通过 `app.infra.storage` 适配 storage，而不是直接依赖 storage DB 实现类。
-- 支持 app/gateway 后续小步迁移，避免一次性大重构。
-
-## 非目标
-
-- 第一阶段不删除旧 persistence。
-- 不让 routers 直接依赖 storage package models。
-- 不让 app routers 管理 SQLAlchemy sessions。
-- cron persistence 不属于 storage package 基础迁移范围。
-- memory backend 不属于 durable storage package。若 app runtime 仍需要 memory 兼容，应放在 `packages/storage` 之外。
-
-## Storage 设计理念
-
-### Package 自己负责 Durable Storage
-
-`packages/storage` 负责应用数据的 durable persistence，包括：
-
-- storage 持久化配置
-- SQLAlchemy models
-- repository contracts 和 DTOs
-- SQL repository 实现
-- persistence factory functions
-- 面向现有 config 的兼容初始化入口
-
-该 package 不应该 import `app.gateway`、routers、auth providers 或 runtime 中的 gateway 对象。
-
-### SQL Backend 兼容
-
-该 package 支持三种 SQL backend：
-
-- SQLite：本地或单节点部署
-- PostgreSQL：生产多节点部署
-- MySQL：使用 MySQL 作为标准数据库的部署
-
-backend 差异在 storage package 内部处理：
-
-- SQLAlchemy async engine URL 构造
-- LangGraph checkpointer 连接串兼容
-- SQLite/PostgreSQL/MySQL 的 JSON metadata filter
-- 不同 SQL 方言在 locking、aggregation、JSON 类型语义上的差异
-
-### 统一 Persistence Bundle
-
-Storage 初始化返回 `AppPersistence` bundle：
-
-```python
-@dataclass(slots=True)
-class AppPersistence:
-    checkpointer: Checkpointer
-    engine: AsyncEngine
-    session_factory: async_sessionmaker[AsyncSession]
-    setup: Callable[[], Awaitable[None]]
-    aclose: Callable[[], Awaitable[None]]
-```
-
-app runtime 只需要初始化一次 persistence，调用 `setup()`，然后注入：
-
-- `checkpointer`
-- `session_factory`
-- repository adapters
-
-这样 checkpointer 和应用数据可以对齐到同一个 backend，同时 routers 不需要理解数据库配置。

-app.state.persistence = persistence
-app.state.checkpointer = persistence.checkpointer
-app.state.session_factory = persistence.session_factory
-```
-
-预期 app shutdown 流程：
-
-```python
-await app.state.persistence.aclose()
-```
-
-## Repository 契约设计
-
-Repository contracts 是 storage package 对外公开的数据访问边界。它们位于 `store.repositories.contracts`，并通过 `store.repositories` re-export。
-
-主要契约包括：
-
-- `UserRepositoryProtocol`
-- `RunRepositoryProtocol`
-- `ThreadMetaRepositoryProtocol`
-- `FeedbackRepositoryProtocol`
-- `RunEventRepositoryProtocol`
-
-每组契约包含：
-
-- 输入 DTO，例如 `UserCreate`、`RunCreate`、`ThreadMetaCreate`
-- 输出 DTO，例如 `User`、`Run`、`ThreadMeta`
-- repository protocol methods
-- 必要的领域异常，例如 `InvalidMetadataFilterError`
-
-Repository 通过 session 构造：
-
-```python
-from store.repositories import build_run_repository
-
-async with persistence.session_factory() as session:
-    repo = build_run_repository(session)
-    run = await repo.get_run(run_id)
-```
-
-这样可以让 transaction ownership 保持明确。storage package 不通过全局 singleton 隐式隐藏 commit 或 session 生命周期。
-
-## App/Infra 调用契约
-
-app 层不应该直接调用 `store.repositories.db.*`。预期的 app 边界是 `app.infra.storage`。
-
-`app.infra.storage` 负责：
-
-- 从 FastAPI runtime 初始化中接收 `session_factory`
-- 为 app-facing repository methods 管理 session 生命周期
-- 在必要时将 storage DTOs 转成 app/gateway DTOs
-- 迁移期间保留现有 app-facing 名称
-- 依赖 storage repository protocols，而不是具体 DB classes
-
-预期 adapter 模式：
-
-```python
-class StorageRunRepository(RunRepositoryProtocol):
-    def __init__(self, session_factory):
-        self._session_factory = session_factory
-
-    async def get_run(self, run_id: str):
-        async with self._session_factory() as session:
-            repo = build_run_repository(session)
-            return await repo.get_run(run_id)
-```
-
-为了兼容 gateway，app state 可以暂时保持现有名字，只替换内部实现：
-
-```python
-app.state.run_store = StorageRunStore(run_repository)
-app.state.feedback_repo = StorageFeedbackStore(feedback_repository)
-app.state.thread_store = StorageThreadMetaStore(thread_meta_repository)
-app.state.run_event_store = StorageRunEventStore(run_event_repository)
-app.state.checkpointer = persistence.checkpointer
-app.state.session_factory = persistence.session_factory
-```
-
-app-facing objects 可以在迁移期间保留旧方法名，但内部数据访问必须经过 storage contracts。
-
-## 边界规则
-
-### 允许调用的范围
-
-storage package 调用方可以使用：
-
-```python
-from store.persistence import create_persistence_from_database_config
-from store.persistence import create_persistence_from_storage_config
-from store.repositories import build_run_repository
-from store.repositories import build_user_repository
-from store.repositories import build_thread_meta_repository
-from store.repositories import build_feedback_repository
-from store.repositories import build_run_event_repository
-from store.repositories import RunRepositoryProtocol
-from store.repositories import UserRepositoryProtocol
-```
-
-app 层应该使用：
-
-```python
-from app.infra.storage import StorageRunRepository
-from app.infra.storage import StorageUserDataRepository
-from app.infra.storage import StorageThreadMetaRepository
-from app.infra.storage import StorageFeedbackRepository
-from app.infra.storage import StorageRunEventRepository
-```
-
-### 禁止调用的范围
-
-app/gateway/router/auth 代码不应该 import：
-
-```python
-from store.repositories.db import DbRunRepository
-from store.repositories.models import Run
-from store.persistence.base_model import MappedBase
-```
-
-routers 禁止：
-
-- 创建 SQLAlchemy engines
-- 直接创建 SQLAlchemy sessions
-- 直接调用 storage DB repository classes
-- 直接 commit/rollback storage transactions，除非这是 infra adapter 明确管理的范围
-- 依赖 storage SQLAlchemy model classes
-
-storage package 禁止 import：
-
-```python
-import app.gateway
-import app.infra
-import deerflow.runtime
-```
-
-依赖方向必须是：
-
-```text
-app/gateway -> app.infra.storage -> packages/storage contracts/factories -> packages/storage db implementations
-```
-
-禁止反向依赖。
-
-## Checkpointer 兼容
-
-storage persistence bundle 会同时初始化 LangGraph checkpointer 和应用数据持久化。
-
-backend 说明：
-
-- SQLite 使用 `langgraph-checkpoint-sqlite`。
-- PostgreSQL 使用 `langgraph-checkpoint-postgres`，需要字符串形式的 `postgresql://...` 连接串。
-- MySQL 使用 `langgraph-checkpoint-mysql`，需要字符串形式的 MySQL 连接串。
-
-SQLAlchemy 可以使用 `postgresql+asyncpg://...` 或 `mysql+aiomysql://...` 这类 async driver URL，但 LangGraph checkpointer 构造函数需要普通字符串连接串。这个转换应该封装在 storage driver implementation 内部。
-
-## JSON Metadata Filtering
-
-Thread metadata search 通过 `store.persistence.json_compat` 支持跨方言 JSON filtering。
-
-支持的 filter value 类型：
-
-- `None`
-- `bool`
-- `int`
-- `float`
-- `str`
-
-拒绝：
-
-- unsafe keys
-- nested JSON path expressions
-- dict/list values
-- 超出 signed 64-bit 范围的整数
-
-这样可以避免 SQL/JSON path injection，避免 compiled-cache 类型漂移，并保留类型语义，例如 `True != 1`，显式 JSON `null` 不等于 missing key。
-
-## 分步实现方案
-
-### 第 1 步：新增 Storage Package 基础
-
-- 新增 `backend/packages/storage`。
-- 增加 storage config models。
-- 增加 `AppPersistence`。
-- 增加 SQLite/PostgreSQL/MySQL persistence drivers。
-- 增加 repository contracts、models、DB implementations 和 factory helpers。
-- 接入 package dependency。
-- 排除 cron persistence。
-
-### 第 2 步：补齐 Storage Backend 兼容性
-
-- 验证 SQLite setup 和 repository 行为。
-- 使用本地 E2E 验证 PostgreSQL 和 MySQL。
-- 修复 checkpointer 连接串兼容。
-- 修复 PostgreSQL locking 和 aggregation 差异。
-- 增加跨方言 JSON metadata filtering。
-
-### 第 3 步：新增 App Infra Adapters
-
-- 新增 `backend/app/infra/storage`。
-- 实现 app-facing repositories，由它们管理 session 生命周期。
-- 保持 storage contracts 作为唯一数据访问边界。
-- 为现有 app/gateway method shape 增加兼容 adapters。
-- 避免 `packages/storage` import app/gateway。
-
-### 第 4 步：切换 FastAPI Runtime 注入
-
-- 在 FastAPI startup/lifespan 中初始化 storage persistence。
-- 将 `persistence`、`checkpointer`、`session_factory` 注入 `app.state`。
-- 暂时保留现有对外 state 名称：
-  - `run_store`
-  - `feedback_repo`
-  - `thread_store`
-  - `run_event_store`
-  - `checkpointer`
-  - `session_factory`
-- 先切 user/auth provider 构造，再逐步迁移 run/thread/feedback/run_event。
-
-### 第 5 步：Router 和 Auth 兼容
-
-- 确保 routers 消费 app-facing adapters，而不是 storage DB classes。
-- 确保 auth providers 依赖 user repository contracts。
-- 保持 router response shapes 不变。
-- 增加 auth/admin/router regression tests。
-
-### 第 6 步：清理旧 Persistence
-
-- app/gateway 迁移完成后，再比较旧 persistence usage。
-- 所有 call sites 迁移完成后，再删除未使用的旧 repository implementations。
-- 只在必要时保留短期 compatibility shims。
-- 从 storage-owned durable persistence 中移除 memory backend 路径。
-
-## 测试策略
-
-单测应覆盖：
-
-- config parsing
-- persistence setup
-- table creation
-- repository CRUD/query behavior
-- typed JSON metadata filtering
-- dialect SQL compilation
-- cron exclusion
-
-E2E 应覆盖：
-
-- SQLite persistence setup
-- PostgreSQL temporary database setup
-- MySQL temporary database setup
-- 所有支持 SQL backend 下的 repository contract 行为
-- JSON/Unicode round trip
-- rollback behavior
-- persistence close/cleanup
-
-如果 CI 暂时没有 PostgreSQL/MySQL services，E2E 可以先作为 local-only 验证保留。

+    """Local-filesystem sandbox provider with per-thread path scoping.
+
+    Earlier revisions of this provider returned a single process-wide
+    ``LocalSandbox`` keyed by the literal id ``"local"``. That singleton could
+    not honour the documented ``/mnt/user-data/...`` contract at the public
+    ``Sandbox`` API boundary because the corresponding host directory is
+    per-thread (``{base_dir}/users/{user_id}/threads/{thread_id}/user-data/``).
+
+    The provider now produces a fresh ``LocalSandbox`` per ``thread_id`` whose
+    ``path_mappings`` include thread-scoped entries for
+    ``/mnt/user-data/{workspace,uploads,outputs}`` and ``/mnt/acp-workspace``,
+    mirroring how :class:`AioSandboxProvider` bind-mounts those paths into its
+    docker container. The legacy ``acquire()`` / ``acquire(None)`` call still
+    returns a generic singleton with id ``"local"`` for callers (and tests)
+    that do not have a thread context.
+
+    Thread-safety: ``acquire``, ``get`` and ``reset`` may be invoked from
+    multiple threads (Gateway tool dispatch, subagent worker pools, the
+    background memory updater, …) so all cache state changes are serialised
+    through a provider-wide :class:`threading.Lock`. This matches the pattern
+    used by :class:`AioSandboxProvider`.

+"""Issue #2873 regression — the public Sandbox API must honor the documented
+/mnt/user-data contract uniformly across implementations.
+
+Today AIO sandbox already accepts /mnt/user-data/... paths directly because the
+container has those paths bind-mounted per-thread. LocalSandbox, however,
+externalises that translation to ``deerflow.sandbox.tools`` via ``thread_data``,
+so any caller that bypasses tools.py (e.g. ``uploads.py`` syncing files into a
+remote sandbox via ``sandbox.update_file(virtual_path, ...)``) sees inconsistent
+behaviour.
+
+These tests pin down the **public Sandbox API boundary**: when a caller obtains
+a ``LocalSandbox`` from ``LocalSandboxProvider.acquire(thread_id)`` and invokes
+its abstract methods with documented virtual paths, those paths must resolve to
+the thread's user-data directory automatically — no tools.py / thread_data
+shim required.

+### PVC User-Data Upgrade Note
+
+Older provisioner versions mounted PVC user-data from `threads/{thread_id}/user-data`. The user-scoped layout mounts from `deer-flow/users/{user_id}/threads/{thread_id}/user-data`.
+
+If an existing deployment already has PVC-backed user-data under the legacy layout, migrate the DeerFlow data directory before relying on the new PVC subPath. Mount the same PVC path that the gateway uses as its DeerFlow base directory, then run the existing user-isolation migration script:
+
+```bash
+cd backend
+PYTHONPATH=. python scripts/migrate_user_isolation.py --dry-run
+PYTHONPATH=. python scripts/migrate_user_isolation.py --user-id <target-user-id>
+```
+
+This moves legacy `threads/{thread_id}/user-data` data under `users/<target-user-id>/threads/{thread_id}/user-data`, which matches the new provisioner PVC subPath when the gateway base directory is mounted at `deer-flow/` on the PVC. Use `default` as the target user only when the legacy data should remain in the default no-auth user namespace. Run the migration while no gateway or sandbox Pods are writing to those paths.
+
 ### Important: K8S_API_SERVER Override
 
 If your kubeconfig uses `localhost`, `127.0.0.1`, or `0.0.0.0` as the API server address (common with OrbStack, minikube, kind), the provisioner **cannot** reach it from inside the Docker container.
