tao.chenandClaude bca239ed4b refactor(backend): split into api/ schemas/ services/ clients/ layers
4-phase restructuring of the previously flat backend/ package. Each
phase lands as a single squash commit so future bisects stay readable
per phase if needed.

## Phase 1 — move + shim (location-only, zero behavior change)
* git mv 14 files into api/ schemas/ services/ clients/ subpackages
  (history preserved via RM/R renames)
* New files: api/{admin,auth,dependencies,jupyter,platform,resources,
  scripts,storage}.py + api/schedules/{schedules,runs}.py
* New files: schemas/{auth,common,jupyter,platform,resources,
  schedules,scripts}.py
* New files: clients/{rclone,runtime,scheduler}.py
* Old paths kept as 1-line `from backend.<new> import *` shims so
  tests/main.py/importers kept working untouched
* schemas/__init__.py now re-exports from backend.schemas.<domain>

## Phase 2 — APIRouter prefix consolidation
* Every APIRouter() now carries its prefix (e.g. prefix="/api/v1/auth")
  and decorators are stripped of the redundant path prefix
* URL paths exposed to the frontend are byte-identical to before
* Affected: api/{auth,jupyter,admin,platform,resources,scripts,
  storage}.py + api/schedules/{schedules,runs}.py

## Phase 3 — first service-layer extraction
* backend.services.schedules.validate_dag moved out of api/
  (pure DAG validator, no Request/BackgroundTasks/DB)
* api/schedules/schedules.py now re-exports the symbol so existing
  4 callsites keep working unchanged
* Added backend/tests/test_validate_dag.py: 8 unit tests covering
  DAG_EMPTY, linear chain, diamond, cycle, self-edge, duplicate
  edge, orphan edge, multi-root ordering

## Phase 4 — delete shims + unify test imports
* Removed 14 flat shim files + schemas/__init__.py
* Migrated 5 test files (32 import sites) to new paths:
  backend.scripts.* → backend.api.scripts.*
  backend.resources.* → backend.api.resources.*
  backend.jupyter.* → backend.api.jupyter.*
  backend.runtime_client.* → backend.clients.runtime.*
  backend.schemas.UpdateScriptRequest → backend.schemas.scripts.*
* audit.py kept at backend.audit (main.py references it; not a
  shim, real code)

## Final structure
backend/src/backend/
  main.py, audit.py, __init__.py
  api/            (10 files: routes + 2 subpackage)
  schemas/        (7 files: Pydantic contracts)
  services/       (storage + schedules)
  clients/        (rclone, runtime, scheduler)

## Verification
* uv run python -m compileall backend/src backend/tests — clean
* uv run --package backend pytest backend/tests -q — 122 passed
  (114 → 114 → 122 → 122 across phases)
* grep -r 'from backend\.\(scripts\|resources\|...\)' backend/ — 0 hits
* git blame --follow still traces file origins through the renames

tao.chen d68055a96c feat(scripts/resources): align list_scripts visibility with list_resources
69a9a48 把 data resources 的可见性从 list 恒真改成
workspace-wide + visibility 过滤 + admin 短路,但 scripts 端
没动。两端不对称,导致:

* 非 admin 调 list_scripts 走 user_relative_path →
  workspace/{当前用户ID}/...,永远拿不到别人的脚本
* count_scripts 同样 user-scoped,dashboard "全部脚本"
  只统计自己
* list_resources 响应没带 owner_display_name,data-only
  owner 的目录名回退到 userId.slice(-6),显示不友好

修复:
* list_scripts / count_scripts 改 workspace-wide(新建
  _build_list_scripts_workspace_descendant_prefix helper;
  旧 _build_list_scripts_descendant_prefix 保留标 deprecated
  避免破坏其它调用方);非 admin 追加
  or_(owner_user_id = me, visibility in {workspace, public})
  与 list_resources 完全对称;admin 短路
* resource_payload 加 owner_display_name 字段(与
  script_payload 对称);list_resources SELECT 加
  Users.display_name + outerjoin
* 前端 ScriptExplorer displayName 回退链:scripts 的
  owner_display_name → data resources 的 owner_display_name
  → 本人 user.display_name → userId.slice(-6) 占位
  ;ResourceItem 类型同步加 owner_display_name?: string|null

存储物理布局仍是 workspace/{user_id}/...,仅读取侧
listing/count 跨 owner。

tao.chen cdcfcb2e43 feat(audit): skip audit log for excluded health/root paths
健康检查与根路径(/health/live、/health/ready、/api/v1/health、
/、/health/storage)没有用户、没业务动作,每秒被 K8s/LB
探针刷一次只会灌进无意义噪音。命中排除集即跳过审计行;
诊断日志(method/path/status/ms 走 stderr)照常打,对容器
运维排错仍有用。

* settings.audit_excluded_paths: list[str] 默认覆盖 5 条
  基础设施路径,env AUDIT_EXCLUDED_PATHS 用逗号分隔
  (pydantic NoDecode + field_validator 兼容 str/list)
* main.py 模块级 _AUDIT_EXCLUDED = frozenset(...),
  access_log 的 success/exception 两条审计行各加守卫
  诊断无条件打
* 测试用 _AccessLogReplica 复刻 access_log 契约(不 import
  真实 main.py),新增 4 个 case:排除根路径、排除 /health/live、
  不排除路径照写审计、自定义排除集

顺带 schedule 模块:ExecutionResult 与 context 已迁到
schedule.domain.*(execution.py / orchestrator.py /
scheduler.py / worker.py),调用点跟进;schedule 自身
18 个测试在改前改后均通过。

tao.chen d2c87de32c refactor(audit): fold audit logging into access_log, drop AuditMiddleware
按用户复查意见把审计折进 main.py 已有的 access_log 中间件,
少一个 middleware、让诊断与合规共用一个出口。

* 删 backend.audit.AuditMiddleware(user_id 解析搬到 main.py
  的 _audit_user_id 模块级 helper,cookie/Bearer 头 + JWT
  验签,失败/缺失一律 '-',全异常捕获不让审计拖死业务)。
* access_log 在 success 路径补 logger.bind(user_id, method,
  path, status).info('audit');exception 路径同样补一条
  status=500 的审计行,然后 re-raise 让全局 handler 转 500。
* 删 app.add_middleware(AuditMiddleware)。
* audit.py 只剩 _DailyFileSink / configure_audit_logging /
  AUDIT_LOG_FORMAT,文件 sink 与 retention 清理逻辑不变。
* 测试改用 _AccessLogReplica 复制 access_log 审计契约(不
  import main.py 避免触发 lifespan 里的 MySQL/engine 初始化),
  删 3 个 middleware 单独 case,加 access_log 端到端 success /
  5xx / 无 JWT 三个 case。

tao.chen 97825ca86d feat(audit): per-request loguru audit middleware with daily rotation
按需为每个 HTTP 接口写一条合规记录到
data/logs/audit/audit-YYYY-MM-DD.log,字段:时间 / 用户 /
METHOD path / 状态码。

设计:
* 复用全局 loguru logger,文件 sink 由 audit._DailyFileSink
  自管:缓存当天文件句柄、跨日重建。不走 loguru 的
  rotation=00:00(产物是 audit.log.YYYY-MM-DD_HH-MM-SS,
  不符合按天单文件的命名要求)。
* AuditMiddleware 只做 CPU 验签拿 user_id:cookie access_token
  优先,Authorization Bearer 兜底,无/坏 JWT 一律记 '-'。
  绝不查 DB(RequestContext 在路由解析后才注入)。
* 审计失败不拖死请求:所有异常捕获。
* 与 main.py 现有 access_log 严格分离:access_log 走 stderr
  诊断(method/path/status/耗时),audit 走独立文件合规
  (时间/用户/接口),并存。
* 启动时按 settings.audit_log_retention_days 清理过期文件
  (设 0 关闭)。
* 新增 settings.audit_log_dir(默认 data/logs/audit,相对 cwd)
  与 settings.audit_log_retention_days(默认 30)两个配置项;
  .env.example 同步。

新增 9 个 case:文件创建、行字段、未登录 '-'、坏 JWT、ULID
path、retention 清理/关闭、Bearer 头、幂等。

tao.chen 2b1f6b5303 perf(jupyter): 5s (workspace_id, user_id) validation cache
Jupyter 一次会话会拉几十次 auth_request(HTML shell / static /
WebSocket / api/contents / autosave / kernels),每次都跑 JWT
verify + WorkspaceMembers JOIN + Scripts.is_locked 查 + runtime
RPC,重复开销大。

新增 module-level (workspace_id, user_id) -> payload 缓存:
* 只缓存 membership 校验通过 + 拿到 runtime 信息的成功结果
  (x-upstream-addr、x-jupyter-internal-token)
* JWT 验签、lock check 仍每请求执行(前者是信任边界,后者
  per-URI 状态易变)
* TTL 5s,time.monotonic(),threading.Lock 保护
* 失败结果(lock 403 / runtime 500)不写缓存

折衷:被踢出 workspace 后最坏 5s 仍返 200;Runtime 单实例下
无需 Redis。新增 8 个 case 覆盖 hit/miss/TTL/lock-every-request/
jwt-every-request/failure-does-not-populate。

tao.chen 69a9a48a0b fix(resources): enforce visibility on list + get (private invisible to non-owner)
回退 5483d19 的 workspace-wide 改动。用户真实语义:
- owner 永远可见自己的资源(含 private)
- 非 owner 只见别人 visibility in {workspace, public} 的资源
- admin 全部可见

can_view 与 list_resources 共享同一谓词。list 端点恢复
owner == me OR visibility in {workspace, public} 的过滤,
admin 跳过。get_resource / download_url / jupyter-relative-path
/ delete_resource 全部经 get_visible_resource → can_view,自然
收敛到同一语义。补 1 个 owner-看自己-private 测试,4 个
visibility 测试保持。
2026-08-21 12:46:09 +08:00
tao.chen 5483d19dbd fix(resources): align can_view with list_resources (workspace-wide)
list_resources 已放开成 workspace-wide,但 can_view 仍要求
visibility in {workspace, public} 或 admin,导致 A 的 private
资源出现在 B 的列表里、但 B 调 GET /{id}、POST /{id}/download-url
与 POST /{id}/jupyter-relative-path 全部 404。

can_view 改为恒真,访问边界全部交给 get_visible_resource 的
workspace_id + status=active SQL 限定;visibility 字段保留为
上传/绑定时的语义标签。delete_resource 仍按 owner/admin 校验
403,不受影响。补 4 个 unit test。

tao.chen 48fe49df3b feat(scripts/data-resources): merge tree + add parent_path filter
- Backend: GET /api/v1/data-resources accepts parent_path; LIKE
  '{ws_id}/%/{escaped}/%' AND NOT LIKE '{ws_id}/%/{escaped}/%/%' on
  StorageObjects.object_key (workspace-wide, escapes _ and %, mirrors
  list_scripts parent_path semantics). 13 new tests in
  test_resources.py (helper unit / SQL compile / SQLite behavioral).
- Frontend: listResources gains parentPath arg, propagated through
  WorkspaceBoundApi + AuthContext binding. WorkspaceTreeGroup title
  count and ScriptExplorer header count now include dataResources.
  memberScriptGroups backfills data-only owners so users with only
  data resources still render a group. loadDataResources accepts an
  optional parentPath, default empty preserves prior behavior.

tao.chen ffec234e40 fix(scripts): actually escape LIKE pattern literals + scope count endpoint
Codex review of #36 + #37 surfaced that my prior `escape="\\"` only
declared the escape character — the pattern literals themselves still
contained unescaped `_` and `%`, so `parent_path="foo_bar"` continued
to match `fooXbar/...`, `foo2bar/...`, etc. My earlier ESCAPE-clause
assertions were tautological: they verified the SQL rendered the
ESCAPE keyword without ever checking that the pattern was actually
escaped. The tests passed; the leak persisted.

Fix in three layers:

1. Real escape: `backend/src/backend/scripts.py` gains
   `_escape_like_pattern(value)` that escapes `\` → `\\`, `%` → `\%`,
   `_` → `\_` (in that order — the escape char MUST be escaped first).
   `_build_list_scripts_descendant_prefix` now returns the escaped
   prefix. `list_workspace_directories` and `delete_workspace_directory`
   also escape their server-built prefixes. `count_scripts` escapes
   the user subtree prefix.

2. Same bug elsewhere: `backend/src/backend/resources.py:404` had the
   identical `DataResources.resource_name.like(f"%{keyword}%")`
   pattern; a search for "100%" would match everything. Now escaped
   too.

3. Count endpoint scope: `count_scripts` was workspace-wide and
   skipped the StorageObjects JOIN. Now INNER JOINs StorageObjects
   (drops orphans whose current_object_id is dangling) and filters
   by `workspace/{user_id}/` subtree so the result matches what
   `list_scripts(parent_path="")` would return. Multi-member
   workspaces no longer over-report, and orphan rows no longer
   inflate the count.

Frontend: `DashboardRoute` is not keyed by workspace/user (only
ScriptsPage is), so without a workspace_id dep the previous
workspace's count persisted across navigation. useEffect now depends
on `currentWorkspace?.workspace_id`; `loadScriptCount` clears the
count to null at the start of the fetch so the dashboard doesn't
flash a stale number.

Tests — backend/tests/test_list_scripts_parent_path.py
- Rewritten with three layers of coverage:
  * Pure helper tests for `_escape_like_pattern` (7 cases including
    backslash-escape-first ordering).
  * SQL-contract tests asserting the COMPILED PATTERN contains the
    escaped form (lowercased to neutralise SQLAlchemy keyword casing).
  * BEHAVIORAL tests on SQLite in-memory with the same LIKE
    semantics — proves the fix actually prevents the wildcard leak.
    Includes a negative test (without escape, siblings DO match) so
    the fixture is verified to exercise the bug.

Tests — backend/tests/test_count_scripts.py
- Updated to assert the JOIN + user-scope filter. New test verifies
  two different users in the same workspace get different subtrees.

Verified:
- pytest backend/tests: 65 passed (43 baseline + 12 list_scripts + 4 count + 6 helper/SQLite behavioral)
- pnpm typecheck: clean
- Raw SQL on MySQL (live DB) confirms `LIKE 'workspace/.../foo\_bar/%%' ESCAPE '\\'`.

tao.chen 79650c61ed feat(scripts): GET /api/v1/scripts/count + DashboardRoute wiring
After #34 the workspace store only holds the root-level scripts plus
whatever subfolders the user has expanded. DashboardRoute's
"全部脚本"/"工作副本" counts derived from scripts.length therefore
underreport the workspace total until the user navigates to /scripts
and expands every folder.

Fix: separate count endpoint + dedicated store field, mounted
independently.

Backend — backend/src/backend/scripts.py
- New endpoint GET /api/v1/scripts/count.
- Route declared BEFORE /api/v1/scripts/{script_id}/... so FastAPI's
  declaration-order matching does not interpret "count" as a script_id.
- Returns { data: { total: number }, meta: {} }; SQL is a single
  COUNT(*) on scripts filtered by workspace_id + status='active'.

Frontend — services/api.ts + context/AuthContext.tsx
- countScripts(workspaceId) client; WorkspaceBoundApi gains the field;
  AuthContext binding forwards workspaceId.

Frontend — state/scriptWorkspaceStore.ts
- scriptCount: number | null, scriptCountLoading: boolean.
- loadScriptCount() action: idempotent (no-op while in-flight), silent
  on failure (dashboard tolerates a stale count).
- Initial state and reset() clear both fields.

Frontend — features/platform/DashboardRoute.tsx
- Subscribes to scriptCount; calls loadScriptCount() on mount.
- Falls back to scripts.length until the count resolves so the
  dashboard never blanks.

Tests — backend/tests/test_count_scripts.py (new)
- 3 unit tests: scalar result handling, NULL coercion, route callable.

Verified: pytest 55 passed (52 + 3 new); pnpm typecheck clean.

tao.chen 9233d99237 fix(scripts): escape LIKE wildcards in tree-walking queries
Codex review of #34 surfaced that folder names containing ``_`` (matches any
single character in SQL LIKE) or ``%`` (matches any sequence) would leak
across sibling paths when used as parent_path / descendant_prefix. Two
endpoints were vulnerable:

- list_workspace_directories (pre-existing, line 780/781, 814/815)
- list_scripts (added in #34, line 1101/1102)

Both had four LIKE calls total, all unescaped. ``safe_directory_name``
allows ``_`` and rejects nothing relevant, so any user-created directory
named e.g. ``foo_bar`` would have its queries silently match
``fooXbar/...`` paths too.

Fix: add ``escape="\\"`` to every .like() / ~.like() call so MySQL emits
``ESCAPE '\\'``. SQLAlchemy doubles the escape character for SQL string
literals (renders as ``ESCAPE '\\\\'``); test asserts the rendered form
appears for both positive and negated clauses in each endpoint.

Also touched get_workspace_tree's `like(like_prefix)` (line 707) and
delete_workspace_directory's `like(f"{child_prefix}%")` (line 1017) —
the prefixes are server-built so technically not user-controllable,
but defense in depth costs nothing.

Verified: pytest 52 passed (50 + 2 new ESCAPE assertions).

tao.chen cee080b7df fix(scripts): AuthContext binding + load() cache invalidation (Codex review)
Codex (deepseek-v4-flash) review of feat(scripts) parent_path filter
surfaced four problems:

1. Critical — AuthContext listScripts binding silently dropped parentPath
   - frontend/app/context/AuthContext.tsx:224 had:
       listScripts: () => rawApi.listScripts(workspaceId)
     so loadScripts("foo/bar") hit GET /api/v1/scripts with no query and
     always received root-level scripts. Typecheck passed because
     `() => ...` is assignable to `(parentPath?: string) => ...`.
   - Fix: forward the parentPath argument.

2. High — load() cache invalidation gap on toolbar refresh / create / delete
   - load() replaced `scripts` with root-only items but never invalidated
     `loadedScriptPaths` for subfolders, so previously-expanded folders
     rendered empty (cached no-op on re-expand) and open tabs pointing
     into subfolders were dropped by the validIds filter.
   - Fix: load() now re-fetches every path currently in
     loadedScriptPaths (and loadedChildPaths for directories), then
     dedups by id/path. On initial mount the cache is empty so this
     degrades to a single root fetch.

3. Low — test docstring overclaimed coverage
   - The "actual ORM roundtrip is covered by the existing integration
     tests" line is false (no other list_scripts test exists).
   - Fix: honest docstring noting the repo has no endpoint integration
     test layer; SQL assertions are brittle to SQLAlchemy/dialect
     formatting.

4. Low — backend docstring overclaimed index role
   - Claimed `idx_storage_workspace_relative_path` "avoided全表扫", but
     the index isn't declared in the ORM model, only exists via the
     baseline migration's upgrade path, and EXPLAIN doesn't drive
     through it (scripts-first plan via idx_scripts_workspace).
   - Fix: accurate description — MySQL drives via idx_scripts_workspace,
     storage_objects PK lookup applies LIKE per row. Notes where to
     optimize if 10万-scale perf becomes a real problem.

Skipped findings (out of scope):
- Medium LIKE escape for `_` / `%` (pre-existing in
  list_workspace_directories; not introduced here).
- Low dashboard `scripts.length` count underreport (separate UI bug,
  pre-existing assumption that broke under the new semantics).

Verified: pytest 50 passed, pnpm typecheck clean.

tao.chen 02c25fcc8e feat(scripts): listScripts parent_path filter + lazy load by directory
Backend — backend/src/backend/scripts.py
- list_scripts accepts optional parent_path Query (default "").
- Extracts _build_list_scripts_descendant_prefix helper for the
  "direct children of parent_path" prefix.
- WHERE clause now adds:
    StorageObjects.relative_path LIKE '<prefix>/%'
    AND NOT LIKE '<prefix>/%/%'
  so deeper descendants and prefix-siblings (foo/bar vs foo/bar2)
  are excluded. Empty parent_path filters to root-level only —
  this is the symmetric, intent-aligned behavior the lazy-load
  frontend relies on.
- EXPLAIN confirms idx_scripts_workspace drives the scripts table;
  storage_objects PK lookup applies the LIKE filter per row.

Frontend — frontend/app/services/api.ts + scriptWorkspaceStore.ts
- listScripts accepts optional parentPath; built URL preserves
  the new filter param.
- Store gains loadedScriptPaths / loadingScriptPaths Sets and a
  loadScripts(parentPath) action: idempotent, in-flight dedupe,
  dedup-by-id when merging into the flat scripts array so existing
  find() callers keep working.
- load() now uses listScripts("") instead of bulk fetch — root
  only on first paint.
- toggleExpanded() triggers loadScripts(parentPath) in parallel
  with loadChildren(parentPath) so folder expansion loads both
  sub-directories and direct-child scripts.

Tests — backend/tests/test_list_scripts_parent_path.py
- 7 unit tests: prefix construction, normalization, traversal
  rejection, and SQL compilation contract (LIKE prefix + NOT LIKE
  prefix + scripts.status filter).

Verified:
- pytest backend/tests: 50 passed (43 existing + 7 new)
- pnpm typecheck: clean
- alembic: no schema changes (migration-less feature)
- EXPLAIN with real workspace: idx_scripts_workspace → PK lookup

tao.chen b600c6810b fix: P0-5 — upload-status rollback, streaming copy (LOCAL only), user re-verify, honest lock
B1: `_mark_upload_failed_and_raise` now commits on a separate session
  - Helper takes `request + upload_id`, opens a fresh session from
    `request.app.state.session_factory` and commits there before raising.
  - Closes the named-lock connection-pool leak Codex flagged: the old
    "commit-on-the-same-session" implementation could return the
    GET_LOCK connection to the pool before the enclosing
    `finally: release_named_lock` ran, leaking `mp:<hash>` for up to
    `pool_recycle` and re-opening the same-key upload race.
  - Same helper now used by `create_server_object_payload`'s put-failure
    branch — two failure paths have identical semantics.

B2: streaming copy for soft-delete + restore (`get_stream() + put()`)
  - LOCAL backend: zero-copy (aiofiles stream write). OOM fixed.
  - S3 backend: still OOMs on multi-GB objects — `put()` materializes
    the async iter via `b"".join(chunks)`. Multipart `put` is a
    follow-up; do NOT claim "OOM fixed on production" since production
    defaults to S3.

C1: worker re-verifies `Users.status='active' AND is_deleted=0`
  - `_assert_user_active` called from `_execution_context` after
    resolving `triggered_by`; skips `SYSTEM_CRON_USER_ID`.
  - `USER_DISABLED` error_code goes into the `NODE_FINISHED_EVENT`
    outbox payload — `schedule_node_runs` has no `error_code` column,
    the row only carries the `message` text. Docstrings corrected to
    say so explicitly (previous docstring falsely promised row-level
    observability).

F1: honest browser-local file lock
  - `api.ts` `acquireFileLock/heartbeatFileLock/releaseFileLock/
    releaseFileLockOnUnload` are now no-ops with comments stating they
    never call the network.
  - `scriptWorkspaceStore` dropped `tickHeartbeats`; `tickCleanup`
    simplified to just clear cache.
  - `useEditSessionLifecycle` dropped its 15s heartbeat `setInterval`.
  - `ScriptWorkspace.tsx` renders `.local-lock-banner` info bar when
    `isEditing`. Two tabs may still silently last-write — banner is the
    only guard (acceptable disclosure-only tradeoff).

Dead code: deleted the duplicate `upload_bytes_to_session` in
`backend/src/backend/storage_api.py`. The `services.storage` import
is now the only source of the function; `create_upload_record`'s
docstring updated to point at `backend.resources`.

tao.chen d8a31bde95 fix: update_script rewrite metadata 2026-08-20 09:57:46 +08:00
tao.chen b6eb069849 fix(backend): enhance storage/resource concurrency, idempotency, and deletion safety
Summary of changes:

- Resources Bind Idempotency (High 1+2):
  - Check existing active storage object bindings before duplicate check.
  - Return existing binding (`reused: true`) on retry with same upload_id.
  - Filter by `status == "active"` to bypass dead/deleted rows during reuse check.

- Storage Concurrent Overwrite (High 3):
  - Add `acquire_named_lock` and `release_named_lock` helpers using MySQL `GET_LOCK`/`RELEASE_LOCK` hashed to <= 64 chars.
  - Wrap `upload_bytes_to_session` PUT+INSERT critical section with named lock on `object_key`.
  - Re-check key collision inside lock; append ULID suffix on collision.

- Shared Reference Deletion Protection (Medium 4):
  - Check active references before deleting storage objects in `delete_resource`.
  - Delete only `DataResources` record if storage object is still referenced elsewhere.

- Robust Usage Type Fallback (Medium 5):
  - Replace direct dict lookup for `USAGE_TYPE_TO_PURPOSE[item.usage_type]` with `.get(..., "workspace")` default.

- Idempotency Key Path Matching (Medium 6):
  - Move `file_name`/`target_path` validation forward and include path dimension in comparison.
  - Strip uniqueness suffix via `_strip_uniqueness_suffix` before key comparison to avoid false 409s on valid retries.

- Usage Type & Bind Concurrency Control (Low 7 & 8):
  - Reject bind requests with 409 if upload session purpose is not `data_resource`.
  - Wrap resource duplicate check and creation in named lock using `(owner, directory, name)`.

- Trash Key Uniqueness & Restore Compatibility (Low 9):
  - Update `trash_key` format to `{purpose}/{object_key}-{storage_object_id}` to prevent collisions.
  - Update `object_key_hash` on trash move.
  - Update restore logic in `storage_api.py` to strip suffix while maintaining backward compatibility with legacy keys.

- Dead Code Removal (Low 10):
  - Remove unreachable `upload_status = "failed"` and redundant `session.rollback()` in `IntegrityError` block.

- Tests & Mocks:
  - Add/update 5 test cases covering non-data_resource bind rejection, suffix stripping, and path recovery.
  - Add named lock statement mocks for DB testing.
