端点与权限码（9 个端点 / 5 个权限码）：

| § | 端点 | 权限码 | 摘要 |
|

|---|---|---|---|
|
||
| T001 | `GET /api/v1/users/me/account/dashboard` | `account:read:self` | 我的账户看板 |
|
||
| T002 | `POST /api/v1/users/me/orders` | `trade:order:create` | 提交委托（首版市价立即成交） |
|
||
| T003 | `GET /api/v1/users/me/orders` | `trade:order:read` | 委托列表 |
|
||
| T004 | `GET /api/v1/users/me/orders/{order_no}` | `trade:order:read` | 委托详情 |
|
||
| T005 | `POST /api/v1/users/me/orders/{order_no}/cancellations` | `trade:order:cancel` | 撤单 |
|
||
| T006 | `GET /api/v1/users/me/holdings` | `holding:read:self` | 持仓列表 |
|
||
| T007 | `GET /api/v1/users/me/transactions` | `trade:txn:read` | 成交记录列表 |
|
||
| T008 | `GET /api/v1/users/me/transactions/{txn_no}` | `trade:txn:read` | 成交详情 |
|
||
| T009 | `GET /api/v1/users/me/cash-ledger` | `account:read:self` | 资金明细 |
|
||
|
||
设计要点：
|
||
- 全部走 `build_request_context`（与 memory / portfolio 一致），数据范围 `self`。
|
||
- 不走限流依赖（`enforce_rate_limit`）——场内交易为低频，由底座网关层限流。
|
||
- 信封用 `envelope` / `list_envelope`，与 §3.3 一致。
