--- name: llmage-module description: Development patterns, architecture, and API reference for the llmage (LLM Manager & Engine) module — Sage platform's LLM lifecycle management system author: Hermes Agent tags: [llm, inference, model-management, billing, sage] --- # llmage Module Skill ## Overview llmage: LLM lifecycle in Sage (registration, display, inference, usage, billing); providers wired via uapi config. ## Accounting Failure Tracking (记账失败) 仪表盘失败数≠记账失败记录列表条数是口径差（llmusage 当前态 vs 只追加审计表，重试/双写会膨胀）。诊断 SQL、文件地图、已知 bug 见 `references/accounting-failed-tracking.md`。 ## Module Location `~/repos/llmage/` ## External Service Registration Registering external GPU/production services into Sage: see `references/external-service-registration.md`. ## Product Sync Chain & providerid Backfill llmage→product_management product sync (load_product_category_product → import_category_products.dspy), backfill SQL for product.providerid, and end-to-end verify/cleanup recipe: see `references/product-sync-providerid.md`. Key pitfall: if a synced field comes back empty, check the source-side SELECT column list first — `getattr(row,'col','')` silently degrades to '' when the sender never selected the column (2026-08 providerid bug). For adding new LLM models from existing providers (llm + llm_api_map + uapiio tables), see `references/new-llm-model-sql-pattern.md`. It covers the three-table relationship, SQL templates, worked examples (kimi-k3), verification approach, and common pitfalls. For adding third-party LLM providers that require multimodal base64 input (no external URL support, e.g. Kimi/Moonshot): see `references/multimodal-uapi-base64.md`. Covers pure Jinja2 uapi template patterns with minimal helper functions registered on `ServerEnv`. ## Architecture: llmage + uapi Collaboration ``` llmage (model business layer) uapi (API gateway layer) │ │ │ llm table │ │ upappid ─────────────────────────→│ upapp table (baseurl, myappid, ownerid, auth_apiname) │ (llm has NO apiname field!) │ │ ──1:N──> llm_api_map ────N:1──→│ (each upapp owns its uapi records directly) │ (apiname, query_apiname, │ │ query_period, ppid, │ │ llmcatelogid) │ │ apiname ─────────────────────→│ uapi table (httpmethod, path, headers, upappid) │ │ │ │ upappkey table (apikey, secretkey) │ │ │ UpAppApi(request) │ │ .stream_linify() ────────────────→│ StreamHttpClient → External LLM API │ .call() ─────────────────────────→│ sync/streaming HTTP call ``` **Key**: `uapiset` table removed. `auth_apiname` moved from `uapiset` to `upapp`. `uapi` links to `upapp` via `upappid` (was `apisetid`). Each upapp owns its uapi records directly. **CRITICAL**: `apiname` is in `llm_api_map`, NOT in `llm` table. JOIN to uapi must go through `llm_api_map.apiname`, not `llm.apiname` (which doesn't exist). ### Inference Flow ``` User clicks model card │ ▼ llm_dialog.ui (LlmIO widget) │ ← if model has multiple catelogs, renders tab buttons │ (HBox + Button per catelog, default = isdefaultcatelog='1') │ Each tab reloads UI with ?id=xxx&catelogid=yyy │ ▼ llminference.dspy → inference_generator() │ ← reads params_kw.llmcatelogid (set by bricks LlmModel) │ ← passes to get_llm(llmid, catelogid) to select correct llm_api_map row │ ├── llm.stream == 'async' ──→ async_uapi_request() ── submit task + background polling ├── llm.stream == False ────→ sync_uapi_request() ─── one-time sync call └── llm.stream == True ─────→ uapi_request() ──────── streaming (SSE) ``` ## Key Tables | Table | Purpose | Key Fields | |-------|---------|------------| | **llm** | Model definition (base metadata) | id, name, model, providerid, ownerid, upappid, enabled_date, expired_date | | **llm_api_map** | Model capability + catalog mapping (1:N) | id, llmid, llmcatelogid, apiname, query_apiname, query_period, ppid | | **llmusage** | Call records (active) | id, llmid, userid, userorgid, usages, status(SUCCEEDED/FAILED), amount, cost, use_time, accounting_status, taskid | | **llmusage_history** | Archived call records (read-only) | Same as llmusage + backup_time | | **llmusage_accounting_failed** | Accounting failure tracking | id, llmusageid, llmid, userid, userorgid, failed_reason, failed_time, retry_count, handled | | **llmcatelog** | Model categories. **ID standardization in progress**: migrating to meaningful abbreviations (t2t, t2v, etc.) managed via appcodes system. | id, name, description | **Note**: `llm_catalog_rel` table **废弃** — catalog relationship is now maintained directly in `llm_api_map`. `llm` table no longer has `llmcatelogid`, `query_apiname`, `query_period`, or `ppid`. All SQL JOINs that previously used `llm_catalog_rel` must now use `llm_api_map` (with `distinct` to handle 1:N duplication). `llm.json`'s subtable is now `llm_api_map`. Management UI: `/llmage/llm_api_map_manage.ui`. **llmcatelog ID standardization**: ✅ COMPLETED (2026-05-30). The `llmcatelog` table now uses meaningful abbreviations as IDs (t2t, t2i, t2v, i2v, r2v, tts, asr, vision, etc.). All v1 API endpoints use backward-compatible SQL matching `(b.id = ${x}$ OR b.name = ${x}$)` so callers can pass either the new ID or legacy Chinese name. See `references/llmcatelog-id-migration.md` for the complete migration record. **llm_api_map**: A multi-ability model (e.g., video generation with t2v/i2v/ref2v) has ONE row in `llm` and multiple rows in `llm_api_map`. Each row links to one `llmcatelogid` and carries ability-specific fields (`apiname`, `query_apiname`, `query_period`, `ppid`). This table replaces the deprecated `llm_catalog_rel` — it carries BOTH catalog relationship AND API capability mapping. ## get_llm() Architecture (Refactored — No More 6-Table JOIN) `get_llm()` was refactored from a 6-table implicit JOIN to a 3-step cached approach: ### Step 1: get_llmage_llm() — 3-table JOIN (llmage DB) ```python sql = """select a.id, a.name, a.model, a.providerid, a.description, a.iconid, a.upappid, a.ownerid, a.min_balance, a.status, m.llmcatelogid, m.apiname, m.query_apiname, m.query_period, m.ppid, m.isdefaultcatelog, lc.name as catelogname from llm a join llm_api_map m on a.id = m.llmid join llmcatelog lc on m.llmcatelogid = lc.id where 1=1 """ # Conditional WHERE logic: # - llmid + catelogid: filter by BOTH (user selected specific catelog) # - llmid only: filter by isdefaultcatelog='1' (default fallback) # - catelogid only: filter by catelogid (list all models of that type) ns = {} if llmid: sql += " and a.id = ${llmid}$" ns['llmid'] = llmid if catelogid: sql += " and m.llmcatelogid = ${catelogid}$" ns['catelogid'] = catelogid else: sql += " and m.isdefaultcatelog = '1'" elif catelogid: sql += " and m.llmcatelogid = ${catelogid}$" ns['catelogid'] = catelogid ``` ### Step 2: _get_uapi_cached() — uapi DB lookup (cached, 5min TTL) ```python uapi = await get_uapi(llm.upappid, llm.apiname) # Returns: ioid, stream, callbackurl, auth_apiname, headers, params, data, response ``` ### Step 3: _get_uapiio_cached() — uapiio DB lookup (cached, 5min TTL) ```python uapiio = await sor.R('uapiio', {'id': uapi.ioid}) # Returns: input_fields (JSON text) ``` ### Merge into llm result ```python llm.ioid = uapi.ioid llm.stream = uapi.stream llm.callbackurl = uapi.callbackurl llm.input_fields = uapiio.input_fields if uapiio else '{}' ``` **Performance**: First call = 3 DB round-trips; subsequent calls = 1 DB + 2 memory cache hits. Faster than old 6-table JOIN after first request. **Cache invalidation**: `invalidate_uapi_cache(upappid, apiname)` for specific entries, no-args for full flush. Exported via `env.invalidate_uapi_cache`. ## LLM API Map Management UI Available at `/llmage/llm_api_map_manage.ui` for logged-in users. Triggered from llm CRUD tool with `llmid` parameter. Features: - Add model capability mappings (catalog, API, query API, polling period, billing program) - View all current mappings in a table - Delete individual mappings - API endpoints: `api/llm_api_map_list.dspy`, `api/llm_api_map_create.dspy`, `api/llm_api_map_delete.dspy`, `api/llm_api_map_options.dspy` - `llmid` is a hidden field passed via `{{params_kw.llmid}}` — not user-selectable ## ServerEnv Functions (via load_llmage()) Available in `.dspy` files via `globals()`: | Function | Purpose | |----------|---------| | `get_llm(llmid, catelogid=None)` | Get model info with uapi/uapiio (cached). Internally calls get_llmage_llm() + cached uapi lookups. For API calls/inference. When `catelogid` is passed, filters to that specific llm_api_map entry (critical for multi-catelog models). | | `get_llmage_llm(llmid=None, catelogid=None)` | Lightweight accessor: llm + llm_api_map + llmcatelog only (for display, accounting, pricing — NOT for API calls). When `llmid` is passed without `catelogid`, filters to `isdefaultcatelog='1'`. | | `get_llm_catelogs(llmid)` | Returns ALL catelog entries for a model: `[{catelogid, catelogname, isdefault}]`. Use in UI templates to render catelog selection tabs when a model has multiple llm_api_map entries. | | `invalidate_uapi_cache(upappid=None, apiname=None)` | Invalidate uapi/uapiio process-level cache. Call when uapi config changes. | | `inference(request, params_kw)` | Inference entry (auto stream response) | | `inference_generator(request, params_kw)` | Inference generator (yields JSON lines) | | `get_llms_by_catelog(catelogid=None)` | Get models grouped by category. Optional `catelogid` filters to a single category. Uses `JOIN llm_api_map` internally (with `distinct`). Each model record includes `pricing_display` — a list of pricing display_text strings from all distinct ppids via `get_pricing_display()`. | | `get_llms_sort_by_provider()` | Get models grouped by provider | | `get_llmcatelogs()` | Get all categories | | `get_llmproviders()` | Get all providers | | `checkCustomerBalance(llmid, userorgid)` | Check if user has enough balance | | `llm_charging(ppid, llmusage)` | Calculate cost via pricing program | | `llm_query_price(llmid, config_data)` | Query price for a model | | `get_asynctask_status(request, taskid)` | Get async task status | | `get_today_asynctask_list(userid)` | Get today's async task list | | `query_task_status(request, luid)` | Manually poll task status | | `llm_query_orders(userorgid, page)` | Query order history | | `backup_accounted_llmusage(cutoff_date)` | Backup accounted records with use_date < cutoff_date to llmusage_history using INSERT SELECT, then DELETE from llmusage. Called by backend_accounting() on date change. | | `get_failed_accounting_records(filters, page, page_size)` | Search accounting failure records with optional filters (userorgid, llmid, handled, start_date, end_date) | | `retry_accounting(llmusageid)` | Reset a failed accounting record to 'created' status for re-processing. Updates failure record: handled='1', retry_count+1. Called by retry_accounting.dspy from the failed accounting UI. | ## OpenAI-Compatible v1 API Endpoints All endpoints use base path `/llmage/v1`. **Unified parameter**: all endpoints use `catelogid` (not `lctype` or `llmcatelogid`). | Endpoint | Method | Purpose | Required Params | |----------|--------|---------|----------------| | `/v1/chat/completions` | POST | Text generation (streaming/sync) | model, prompt or messages. Optional: `catelogid` (default "t2t") | | `/v1/models` | GET | List available models (OpenAI format) | Optional: `catelogid` (filter) | | `/v1/models/catelog` | GET | List models by catalog (full detail) | catelogid. Optional: `exclude_id` | | `/v1/tasks` | GET | Query async task status | taskid | | `/v1/video/generations` | POST | Video generation (async) | model, catelogid, prompt | | `/v1/image/generations` | POST | Image generation (sync only) | model, catelogid, prompt | | `/v1/music/generations` | POST | Music generation (sync) | model, catelogid="music_gen", prompt, lyrics | | `/v1/audio/speech` | POST | Text-to-speech / TTS (stream) | model, catelogid="tts", prompt. Optional: speaker, speed, emotion | | `/v1/audio/transcriptions` | POST | Speech recognition / ASR (sync) | model, catelogid="asr", audio_file | | `/v1/pricing` | GET | Model pricing display info | model. Optional: catelogid (default "t2t") | **Backward-compatible catalog matching**: All v1 endpoints accept `catelogid` as either the new abbreviation ID (`t2t`, `t2v`, `i2v`, etc.) or the legacy Chinese name (`文生文`, `文生视频`, `图生视频`). SQL uses `(b.id = ${catelogid}$ OR b.name = ${catelogid}$)`. **Common flow**: validate params → lookup llm via `llm` + `llm_api_map` + `llmcatelog` JOIN → `checkCustomerBalance()` → dispatch to `inference()` (routes to sync/streaming/async based on model config). **RBAC**: All v1 endpoints require `logined` permission. Each endpoint needs both directory and file path entries in `load_path.py`: ``` /llmage/v1/video/generations logined /llmage/v1/video/generations/index.dspy logined ``` **File naming**: v1 endpoints can use either `index.dspy` (under a subdirectory, e.g. `v1/models/index.dspy` → `/v1/models`) or a direct file (e.g. `v1/models/catelog.dspy` → `/v1/models/catelog`). Direct files work for flat endpoints that don't need their own directory. RBAC entries must match the actual file path exactly. ## Three Inference Modes ### 1. Streaming (uapi_request) — for SSE-capable LLMs ```python async for line in uapi_request(request, llm, callerid, callerorgid, params_kw): yield line # JSON lines: {"content": "..."}, {"usage": {...}} ``` ### 2. Synchronous (sync_uapi_request) — for one-shot responses ```python result = await sync_uapi_request(request, llm, callerid, callerorgid, params_kw) ``` ### 3. Asynchronous (async_uapi_request) — for long-running tasks (video generation) ```python result = await async_uapi_request(request, llm, callerid, callerorgid, params_kw) # Returns: {"taskid": "xxx", "status": "PENDING"} # Background auto-polls via query_task_status() ``` ## Billing System - **Online calls do NOT charge immediately** — mark `accounting_status='created'` - **Background task** `backend_accounting()` runs every 10 seconds, processes all 'created' records - **Balance check**: `checkCustomerBalance(llmid, userorgid)` returns False if balance < llm.min_balance. ALL requests go through balance check — no bypass for owner organization. - **Failure tracking**: When accounting fails, `llm_accoung_failed(luid, reason)` records the failure in `llmusage_accounting_failed` table with `failed_reason`, `failed_time`, and `handled='0'`. Use `get_failed_accounting_records()` to search failures. Frontend at `/llmage/failed_accounting.ui`. - **History backup**: `backend_accounting()` detects date changes in its 10-second loop (tracking `last_backup_date`). When the date changes, it computes `yesterday = today - 1 day` and calls `backup_accounted_llmusage(yesterday)` exactly once per day. This uses `INSERT INTO ... SELECT FROM` (single SQL) to batch-copy `accounting_status='accounted'` records with `use_date < yesterday` to `llmusage_history`, then `DELETE` (single SQL) to remove them from `llmusage`. Keeps the active table lean while retaining yesterday's data for one full day. - **Accounting status values**: `'created'` (pending), `'accounted'` (success), `'failed'` (error — see llmusage_accounting_failed for details) ### Pricing Engine Internals See `references/pricing-engine-internals.md` for: - `price_factors: flat` vs `price_factors: ` behavior - Per-model ppid isolation requirement (shared ppid → billing mismatches) - Cache behavior (`get_ppid_pricing` caches by `{ppid}.{date}`) - `enabled_date` requirement - Accounting query conditions - Verification flow with concrete numbers ## Permission Setup for New Endpoints **Deployment workflow**: See `references/sage-endpoint-deployment.md` for the complete 6-step process to deploy new v1 endpoints to tokentest/production Sage instances (deploy dspy → update load_path.py → run load_path.py → fix rolepermission → restart Sage → verify). **Every new `.ui` and `.dspy` file needs RBAC permission records.** Without them, users get HTTP 401. ### Preferred: Shell Script (`scripts/setup__perms.sh`) Follow the Sage convention used in `setup_rbac_perms.sh`. `set_role_perm.py` handles both permission insertion AND role assignment — if the path doesn't exist in `permission`, it auto-creates it: ```bash #!/bin/bash set -e SCRIPT_DIR="$(cd "$(dirname "$0")" && pwd)" SAGE_DIR="$(cd "$SCRIPT_DIR/../.." && pwd 2>/dev/null || echo "")" cd "$SAGE_DIR" set_perm() { python set_role_perm.py "$1" "$2" } PERM_ROLES=("owner.superuser" "owner.admin" "reseller.admin" "reseller.operator") FEATURE_PATHS=("/llmage/new_page.ui" "/llmage/api/new_action.dspy") for p in "${FEATURE_PATHS[@]}"; do for role in "${PERM_ROLES[@]}"; do set_perm "${role}" "${p}" done done ``` **v1 API endpoints need SEPARATE customer role permissions.** The v1 endpoints are customer-facing (Bearer token auth via dapi module). Admin/operator roles alone are NOT sufficient — customers get 403 without explicit customer role entries: ```bash CUSTOMER_ROLES=("customer.admin" "customer.user") V1_API_PATHS=( "/llmage/v1/chat/completions/index.dspy" "/llmage/v1/video/generations/index.dspy" "/llmage/v1/image/generations/index.dspy" "/llmage/v1/music/generations/index.dspy" "/llmage/v1/audio/speech/index.dspy" "/llmage/v1/audio/transcriptions/index.dspy" "/llmage/v1/models/index.dspy" "/llmage/v1/models/catelog.dspy" "/llmage/v1/tasks/index.dspy" "/llmage/v1/pricing/index.dspy" ) for p in "${V1_API_PATHS[@]}"; do for role in "${CUSTOMER_ROLES[@]}"; do set_perm "${role}" "${p}" done done ``` Similarly, in `load_path.py`, customer v1 paths need a separate `PATHS_V1_CUSTOMER` list registered under customer roles, distinct from the `PATHS_LOGINED` list: ```python PATHS_V1_CUSTOMER = [ f"/{MOD}/v1/chat/completions/index.dspy", f"/{MOD}/v1/video/generations/index.dspy", f"/{MOD}/v1/image/generations/index.dspy", f"/{MOD}/v1/music/generations/index.dspy", f"/{MOD}/v1/audio/speech/index.dspy", f"/{MOD}/v1/audio/transcriptions/index.dspy", f"/{MOD}/v1/models/index.dspy", f"/{MOD}/v1/models/catelog.dspy", f"/{MOD}/v1/tasks/index.dspy", ] # In main(): for role in ["customer.admin", "customer.user"]: total += register_role_paths(role, PATHS_V1_CUSTOMER) ``` ### Fallback: Production SQL Migration For production database changes (executed by the user): ```sql INSERT INTO permission (id, path) SELECT REPLACE(UUID(), '-', ''), '/your/new/path.dspy' WHERE NOT EXISTS (SELECT 1 FROM permission WHERE path = '/your/new/path.dspy'); ``` ID must be 32-char hex string (no dashes). Use `REPLACE(UUID(), '-', '')` in SQL or `getID()` in Python. ### Permission Path Convention Paths are relative to the module's `wwwroot/` directory: - `wwwroot/index.ui` → `/llmage/index.ui` - `wwwroot/api/list.dspy` → `/llmage/api/list.dspy` ## Data Isolation Pattern **Do NOT add redundant `orgid`/`ownerid` columns to child tables.** Instead, JOIN to the parent table's `ownerid` for filtering and permission verification: ```python # In DSPY files user_orgid = await get_userorgid() # JOIN parent table for ownership check sql = "select m.* from llm_api_map m join llm l on m.llmid = l.id where l.ownerid = ${ownerid}$" ``` ## Publish/Unpublish (上架/下架) Models have a `status` field controlling visibility: - `published` — visible to users in all display pages and usable for inference/API calls - `unpublished` (default) — only visible in CRUD management interface ### Affected Query Points (all filter `a.status = 'published'`) - **utils.py**: `get_llms_by_catelog_to_customer()`, `get_llms_by_catelog()`, `get_llm()`, `get_llmproviders()`, `get_llms_sort_by_provider()` - **v1 endpoints**: `chat/completions`, `image/generations`, `video/generations` (model name lookup) - **User pages**: `t2t/index.dspy`, `get_type_llms.dspy`, `list_catelog_models.dspy`, `list_paging_catelog_llms.dspy`, `llmcheck.dspy` ### NOT filtered (admin/internal) - `api/llm_list.dspy` — CRUD list shows ALL models - `api/llm_create.dspy`, `api/llm_update.dspy` — CRUD operations - `accounting.py` — backend accounting processes all records - `get_llm_by_model()` — utility function, not called by user-facing code ### Migration `sql/add_status_field.sql`: ALTER TABLE + UPDATE SET status='published' for existing models + index on status. ## Testing v1 APIs ### Authentication v1 endpoints use Bearer token auth via the `dapi` module. The auth chain: 1. `bearer_auth()` extracts token from `Authorization: Bearer ` header 2. `get_apikey_user()` encrypts the key via `password_encode()` (RC4) and looks it up in `downapikey` table 3. Joins `users` and `downapp` tables; checks `downapp.allowedips` for IP whitelist 4. Returns user if all checks pass, `None` otherwise → 401/403 **Different downapp keys have different permission scopes.** A key that works for `/v1/chat/completions` may return 401 on `/v1/image/generations` or `/v1/video/generations`. When testing, verify the key has access to ALL target endpoints. ### Testing Workflow When writing automated test scripts for llmage v1 APIs: - **Always read the API key from `~/.hermes/config.yaml`** (`model.api_key`), never hardcode or manually type it. Hardcoded keys lead to wasted debugging time on auth failures. - **Include `catelogid` for image/video endpoints**: These are mandatory parameters. Without `catelogid`, endpoints return 400 "Missing required parameter". - **`catelogid` accepts abbreviation IDs or Chinese names**: Pass `"t2v"`, `"t2i"`, `"i2v"` (recommended) or legacy Chinese names `"文生视频"`, `"文生图"`, `"图生视频"`. Both work via backward-compatible SQL matching. - **`/v1/chat/completions`**: `catelogid` is optional (defaults to `"t2t"`). Only `model` + `messages` required. - **Handle non-JSON responses**: Some endpoints return `401: Unauthorized` as plain text, not JSON. Parse with try/except. See `references/v1-api-testing.md` for a complete test script template. ## Pitfalls See `references/pitfalls-27-33.md` for additional pitfalls (accounting, tenantid, ASR uapi, backend process). 1. **llm.stream field controls mode**: `'async'` = async task, `False` = sync, `True` = streaming 2. **新增v1端点前必须先学习现有模式**: 不要盲目创建 dspy 文件。先读现有 v1 端点（如 `/v1/chat/completions/index.dspy`）了解正确的 dspy 结构、SQL JOIN 模式、错误处理方式。用户明确纠正："不能自己瞎做，改学习一下uapi和llmage的API接口skill和规范"。下午会话的工作应该被继承，不是重新发明。默认使用 `openai_403()`/`openai_400()`/`openai_429()` 错误返回（非 `UiError`）。`/v1/media/{apiname}` 每端点需独立目录+index.dspy（非catch-all）。模板和部署流程见 `references/v1-media-dspy-template.md`。 3. **llm ↔ uapi bridge**: llm table's `upappid` + llm_api_map's `apiname` must match existing uapi configuration. JOIN chain: `llm → upapp → uapi` (no uapiset). 3. **BufferedLLMs cache**: Model definitions cached by date (`{llmid}.{date}`), auto-expire on day change 4. **IO persistence**: Input/output stored as JSON files via FileStorage; llmusage.ioinfo is the webpath 5. **API key protection**: Exception messages are sanitized by `erase_apikey()` — Bearer tokens replaced with XXXXXXXX 6. **Async query_apiname**: Can be comma-separated; each API name is polled in sequence until SUCCEEDED/FAILED 7. **query_period**: Polling interval in seconds (default 30), configured in llm_api_map table (NOT llm table) 8. **ppid**: Pricing program ID is in llm_api_map table. `llm_query_price` reads it from the BufferedLLMs result. 9. **New model requires uapi setup first**: upapp → uapi → upappkey → llm + llm_api_map (in that order). NO uapiset. 10. **input_fields**: Model input field definitions stored in uapiio table, auto-linked by BufferedLLMs 11. **llm_api_map migration**: When adding llm_api_map to an existing system, migrate existing llm data first (apiname, query_apiname, query_period, ppid) into llm_api_map rows before deploying code changes. 12. **uapiset removed**: All JOINs must not reference uapiset. `auth_apiname` is now on the `upapp` table. `uapi` links to `upapp` via `upappid` (each upapp owns its own uapi records). 14. **bricks subtable limitation**: A CRUD JSON `subtables[]` can only bind ONE subtable. When switching from `llm_catalog_rel` to `llm_api_map` as the subtable, you cannot have simultaneous CRUD for both tables from `llm.json`. Create an independent management UI (`llm_api_map_manage.ui`) with its own list/create/delete DSPYs. 15. **llm_catalog_rel 已废弃**: 所有 SQL JOIN 中引用 `llm_catalog_rel` 的地方必须改为 `llm_api_map`。因为 `llm_api_map` 是 1:N 关系，select 需加 `distinct` 去重。受影响文件：`utils.py` (get_llms_by_catelog, get_llms_by_catelog_to_customer)、所有 `*.dspy` 查询文件、`init.py` 事件绑定。 16. **Pre-existing llmusage.json float fields missing `dec`**: The existing `models/llmusage.json` and `models/llmusage.xlsx` define `responsed_seconds`, `finish_seconds`, `amount`, `cost` as `"type": "float"` with `"length": 18` but NO `"dec"`. `json2ddl` produces invalid `double(18,)` syntax. When creating new history/failed tables that mirror these fields, use `"type": "double"` with both `"length": 18` AND `"dec": 5` (for amount/cost) or `"dec": 3` (for seconds). The pre-existing issue in llmusage.json itself is a known debt item — changing it would regenerate DDL for the existing table. 17. **Pre-existing CRUD gaps**: `json/llm.json` and `json/llm_api_map.json` are missing the mandatory `editable` paragraph (spec Pitfall 7). `json/llm.json` also has `browserfields.alters` referencing `"ppid"` — this field was moved from `llm` to `llm_api_map` during the uapiset removal migration, so the alters reference is broken. These are known debt items. 18. **Read-only CRUD pattern for archive tables**: When a table is append-only or read-only (e.g., `llmusage_history`), still provide `editable` in the CRUD JSON per spec, but point create/update/delete DSPYs to stub endpoints that return `{'success': False, 'message': '只读'}`. This satisfies the spec validator while enforcing read-only at the API level. 19. **backup_accounted_llmusage uses INSERT SELECT for efficiency**: The function executes a single `INSERT INTO llmusage_history SELECT FROM llmusage` followed by a single `DELETE FROM llmusage` — both with the same WHERE clause (`accounting_status='accounted' AND use_date < cutoff_date`). Do NOT rewrite as Python loop (sor.C + sor.D per row) — this is orders of magnitude slower for large datasets and lacks atomicity. The `cutoff_date` is always `yesterday` (today - 1 day), passed by `backend_accounting()` on date change. 20. **Indexing for large llmusage/llmusage_history/llmusage_accounting_failed tables**: These tables grow rapidly. Essential indexes: - `llmusage`: `(accounting_status, use_date)` — for backup SELECT queries - `llmusage_history`: `(use_date)`, `(userid)`, `(userorgid)`, `(llmid)`, `(backup_time)` — for historical queries - `llmusage_accounting_failed`: `(handled)`, `(failed_time)`, `(use_date)`, `(userid)`, `(userorgid)`, `(llmid)` — for failure record searches and filtering 21. **Accounting failure lifecycle**: When `backend_accounting()` fails to process a record, `llm_accoung_failed(luid, reason)` does two things: (a) sets `llmusage.accounting_status='failed'` so the record stays in the active table, and (b) INSERTs a tracking row into `llmusage_accounting_failed` with `retry_count=0`, `handled='0'`. Failed records can be retried via the "重试" button on `/llmage/failed_accounting.ui`, which calls `retry_accounting.dspy` to reset `accounting_status='created'` (picked up by the next loop iteration) and mark the failure record as handled with `retry_count+1`. Manual handling without retry: mark `handled='1'`, set `handled_time`/`handled_note`. 22. **Graceful table-existence detection for migrations**: When adding new tables (e.g., `llmusage_history`, `llmusage_accounting_failed`) to a live production system, use `_table_exists(sor, tablename)` probe before querying to prevent crashes before the migration SQL is executed. Pattern: `await sor.sqlExe(f"SELECT 1 FROM {tablename} LIMIT 0", {})` wrapped in try-except. Returns True if table exists, False otherwise. Module code should fallback gracefully when the table doesn't exist yet. See `references/graceful-migration-patterns.md` in the sqlor-database-module skill. 23. **v1 API endpoints require explicit RBAC entries for deep paths AND customer roles**: Endpoints under `/v1/` subdirectories (e.g., `/v1/video/generations/index.dspy`) need explicit RBAC permission entries. The parent `/llmage logined` entry does NOT cover nested paths. Each endpoint needs both the directory and the `index.dspy` file path registered. **Additionally, v1 endpoints are customer-facing (Bearer token auth via dapi) — they need customer.admin and customer.user role permissions, NOT just admin/operator roles.** Without customer role entries, customers get 403 even with valid API keys. Missing entries cause 403 errors with no indication in server logs — the request is rejected at the RBAC middleware level before reaching the .dspy file. **Direct file endpoints** (e.g. `v1/models/catelog.dspy`) only need the file path entry, not a separate directory entry. 24. **get_llmage_llm() vs get_llm() — architecture after refactor**: - `get_llmage_llm(llmid=None, catelogid=None)` — lightweight 3-table JOIN (llm + llm_api_map + llmcatelog). Use for display, accounting, pricing, listing. Returns `None` when called with llmid and not found; returns `list` when called with catelogid or no args. - `get_llm(llmid, catelogid=None)` — calls `get_llmage_llm()` internally, then adds uapi/uapiio fields via **cached lookups** (not JOIN). Use when you need `input_fields`, `stream`, `ioid`, `callbackurl` (i.e., inference/API calls). Returns merged DictObject. - **Refactored from 6-table JOIN to 3-step + cache**: Step 1 = `get_llmage_llm()` (3-table JOIN), Step 2 = `_get_uapi_cached(upappid, apiname)` (process-level cache, 5min TTL), Step 3 = `_get_uapiio_cached(ioid)` (process-level cache, 5min TTL). Fields merged into result: `llm.ioid`, `llm.stream`, `llm.callbackurl`, `llm.input_fields`. - **Cache management**: `invalidate_uapi_cache(upappid=None, apiname=None)` — call when uapi config changes. Specific key invalidation with both args; full flush with no args. Exported via `env.invalidate_uapi_cache`. - **Pitfall**: `get_llm()` still requires uapi records to exist (via `_get_uapi_cached`). If a model has no uapi config yet, `get_llm()` returns None but `get_llmage_llm()` returns the model data. Use the right one for the context. - All non-inference code paths (`checkCustomerBalance`, `llm_accounting`, `llm_query_price`) should use `get_llmage_llm()`. 25. **v1 endpoints use backward-compatible SQL matching, BUT llm_api_map migration is incomplete**: All v1 endpoints (`v1/chat/completions`, `v1/video/generations`, `v1/image/generations`, `t2t/index.dspy`, `get_type_llms.dspy`) use `WHERE (b.id = ${catelogid}$ OR b.name = ${catelogid}$)` for matching against `llmcatelog`. External API callers can pass the abbreviation ID (e.g., `"t2v"`) or Chinese name (e.g., `"文生视频"`). **However**: `llm_api_map.llmcatelogid` was NOT updated during migration — it still references old IDs (text2text, text2image, text2video, image2text). This breaks the JOIN chain `llm → llm_api_map → llmcatelog` for image/vision/TTS catalogs. Only `t2t` works because some `llm_api_map` records were individually updated. Fix: UPDATE `llm_api_map` to use new abbreviation IDs matching `llmcatelog.id`. 26. **v1 image/video endpoints require `catelogid` parameter**: Unlike `/v1/chat/completions` (where catelogid defaults to "文生文"), image and video endpoints return 400 "Missing required parameter" if `catelogid` is omitted. Always include it in test payloads. 27. **API testing: always read key from `~/.hermes/config.yaml`**: When writing automated test scripts for v1 APIs, read `model.api_key` from config.yaml programmatically. Never hardcode or manually type the API key — the user corrected this explicitly. Hardcoded keys waste debugging time on auth failures when the real issue is just using the wrong key. 28. **Different downapp keys have different v1 endpoint scopes**: The `downapikey` + `downapp` auth system means some API keys only work for certain v1 endpoints. A key that successfully calls `/v1/chat/completions` may return 401 on `/v1/image/generations` or `/v1/video/generations`. When all text models pass but all image/video models fail with 401, the issue is likely the key's permission scope, not the API itself. 29. **llmcatelog vs llm_api_map ID migration inconsistency (critical)**: After the llmcatelog ID standardization, `llmcatelog.id` was updated to new abbreviations (t2t, t2v, t2i, etc.) but `llm_api_map.llmcatelogid` still references the OLD IDs (text2text, text2video, text2image, image2text, etc.). This causes JOIN failures: `catelogid=t2i` matches `llmcatelog.id='t2i'` but `llm_api_map.llmcatelogid='text2image'` doesn't JOIN to it. Result: `?catelogid=t2i` returns 0 models, while `?catelogid=t2t` returns 23 (because `t2t` happens to exist in llm_api_map too). **Fix required**: UPDATE `llm_api_map` SET `llmcatelogid` to new abbreviations matching `llmcatelog.id`. Until fixed, image/vision/TTS catalog filters are broken on v1/models endpoint. 30. **uapi data template can be empty — causes upstream "Parameters error"**: When a uapi record has an empty `data` template (like the 即梦 tongyi-wan t2i models), the upstream API call sends no request body, resulting in a 400 "Parameters error" from the external provider. The v1 endpoint code itself works correctly — it's the uapi configuration that's incomplete. When debugging 400 errors from v1 endpoints, always check the uapi.data template is populated, not just the v1 endpoint code. 31. **upappkey quota can cause 400/429 from upstream**: When the upstream provider's API key (stored in `upappkey` table) has exhausted its quota, the external API returns 429 "insufficient_quota" which gets passed through to the v1 caller. This is indistinguishable from a parameter error without checking the upstream response details. 32. **Video generation API responses are Python dict strings, not JSON**: The async video generation endpoints return responses using Python dict syntax (single quotes), not valid JSON. `resp.json()` throws `JSONDecodeError`. Always parse with `ast.literal_eval()` as fallback. Content-Type header may be `text/html` even on HTTP 200. This applies to all async inference responses (video, image generation). 33. **API callers must use uapiio input_fields names exactly**: When calling `/v1/video/generations` or `/v1/image/generations`, the parameter names in the request body must match the `name` values defined in the model's uapiio.input_fields. For example, if uapiio defines `{"name": "image_file", ...}`, the API request must use `image_file` as the key — NOT `image_url`. The uapi.data Jinja2 template references `{{image_file}}` and will throw `UndefinedError` if the field name doesn't match. To discover correct field names: `llm → llm_api_map → uapi.ioid → uapiio.input_fields`. 34. **Seedance Ref2V requires `ratio` parameter despite doc saying optional**: The doubao-seedance-2-0-260128 model's r2v endpoint returns 400 Bad Request from upstream Volcengine Ark API if `ratio` is omitted. API.md documents it as optional with default value, but the upstream API actually requires it. Always include `ratio` (e.g., `"16:9"`) in Seedance Ref2V requests. 35. **Vidu Ref2V has two separate proxy bugs**: - **viduq3-pro r2v**: All parameter combinations (images array, subjects array, image_file) return "Parameters error" from upstream Vidu API. The uapi.data template's parameter structure doesn't match what Vidu expects. - **viduq2-pro/vidu2.0 r2v**: URL path duplication — `upapp.baseurl` already contains `/ent/v2`, and `uapi.path` also includes it, producing malformed URL like `https://api.vidu.cn/ent/v2/ent/v2/reference2video`. - **viduq3-turbo**: Not configured for r2v catelog at all (no llm_api_map entry). 36. **Video API responses use inconsistent status values**: Different providers return different status strings — Seedance uses `"CREATED"`, HappyHorse uses `"PENDING"`, Vidu uses `"created"`. Client code should normalize to uppercase for comparison. 37. **API documentation drift — update docs whenever modifying ANY service behavior**: This applies to v1 endpoints, v1/media GPU service endpoints, and any service whose external API contract changes. When you modify a service endpoint's parameters (adding `task_type`, changing response format, adding new modes like `separate_full`), the API docs MUST be updated in the same session. The user explicitly corrected this: "api文档也也要同步更新". This is NOT optional.\n\n **Multiple doc locations**: `~/repos/llmage/wwwroot/api_doc.md`, `~/repos/llmage/docs/API.md`, `~/repos/dashboard_for_sage/wwwroot/api_doc.md`. At minimum update `dashboard_for_sage/wwwroot/api_doc.md` (customer-facing) and `llmage/docs/API.md` (developer-facing).\n\n **Also update the model description** in the llm table or API doc model list when adding capabilities (e.g., changing "人声/伴奏分离" to "人声/伴奏分离（支持MIDI乐器替换）").\n\n Public API doc (`~/repos/sage/wwwroot/public/api/api_zh.md`) was left stale for months — the old doc still referenced `llmid` (UUID) and `/llmage/video` instead of `model+catelogid` and `/llmage/v1/video/generations`. When adding/changing v1 endpoints, update the API doc in the same session. Always use `model` (string name) + `catelogid` (abbreviation) in examples, never `llmid` (UUID). 38. **DashScope API versioning — wan2.7 uses completely different endpoint and request format**: Newer DashScope models (wan2.7 series) use a different API endpoint and request body structure than older models (wan2.2 series). **wan2.2**: endpoint `/api/v1/services/aigc/text2image/image-synthesis`, request body `{"model": "...", "input": {"prompt": "..."}, "parameters": {...}}`. **wan2.7**: endpoint `/api/v1/services/aigc/multimodal-generation/generation`, request body `{"model": "...", "input": {"messages": [{"role": "user", "content": [{"text": "..."}]}]}, "parameters": {...}}`. When integrating new DashScope models, **always check the official API documentation** for the correct endpoint and request format — do not assume backward compatibility with existing `tongyi-wan` uapi configurations. The `llm.apiname` field must point to a uapi record configured for the correct endpoint version. See `references/dashscope-api-versioning.md` for endpoint comparison and uapi configuration examples. 39. **DashScope status endpoint is shared — do NOT create duplicate status uapi records**: DashScope's task query endpoint `GET /tasks/{task_id}` is unified across ALL models under the same provider (upappid=tongyi-wan). Whether the task was created via `/text2image/`, `/multimodal-generation/`, or `/image-generation/`, the status query is always the same. If a status uapi (e.g., `wan-t2i-status`) already exists for the upappid, **reuse it** in llm_api_map.query_apiname. Creating per-model status uapis wastes records and causes confusion. 40. **Prefer sync mode when DashScope supports it**: Official docs explicitly recommend sync ("一次请求即可获得结果，流程简单，推荐大多数场景使用"). Sync uses `stream='sync'` in uapi and eliminates the need for status polling (no query_apiname needed in llm_api_map). Only use async for genuinely long-running tasks where sync would timeout. 41. **Async task polling stuck at CREATED after schema migration**: After moving `query_apiname` and `query_period` from `llm` to `llm_api_map`, the `get_llm_llmusage()` function in `asyncinference.py` still used `sor.R('llm', {'id': llmid})` — a direct table read that only returns `llm` table fields. This caused `llm.query_apiname` to be `None`, crashing `query_task_status()` with an `AttributeError` that was silently swallowed, leaving `llmusage.status` permanently stuck at "CREATED". **Fix**: Replace `sor.R('llm', ...)` with a JOIN query: `SELECT a.*, m.query_apiname, m.query_period FROM llm a JOIN llm_api_map m ON a.id = m.llmid WHERE a.id = ${llmid}$ AND m.isdefaultcatelog = '1'`. **General rule**: When schema migration moves fields between tables, scan ALL code paths (not just the ones you're actively working on) for direct table reads (`sor.R`) that need updating. Background tasks like polling are especially vulnerable because errors may be silently caught. 39. **"Model exists but doesn't work" diagnostic checklist**: When a model is registered in the `llm` table but fails during inference or doesn't appear in category listings, check these in order: 1. **llm_api_map entry exists?** — `SELECT * FROM llm_api_map WHERE llmid = ''`. Without this, the model has no API capability mapping and won't appear in `get_llmage_llm()` results. 2. **uapi record matches the model's API version?** — `llm_api_map.apiname` must point to a `uapi` record whose `path` and `data` template match the provider's current API format. New model versions (e.g., wan2.7 vs wan2.2) may need entirely new uapi records. 3. **upappkey exists for the provider?** — `SELECT * FROM upappkey WHERE upappid = ''`. Without API credentials, calls will fail. 4. **llm.status = 'published'?** — Unpublished models are invisible to users. 5. **llm_api_map.llmcatelogid matches llmcatelog.id?** — After the ID standardization, old IDs (text2image, text2video) won't JOIN to new abbreviation IDs (t2i, t2v). 40. **Async task response uses `taskstatus` field, NOT `status`**: When submitting an async image/video generation request, the response body is `{"taskid": "xxx", "taskstatus": "PENDING"}` — note the field name is `taskstatus`, not `status`. The `/v1/tasks` query endpoint also returns `taskstatus` inside `data`. The API doc previously showed `status` and an outer `{"status":"ok","data":{...}}` wrapper for submit — this was wrong. Actual submit response is direct (no wrapper): `{"taskid":"...","taskstatus":"PENDING"}`. Task query wraps in `{"status":"ok","data":{"taskid":"...","taskstatus":"PENDING"}}`. When SUCCEEDED, the data block contains `image`/`output` fields directly. Always use `taskstatus` when parsing async responses programmatically. 41. **Sync inference responses have NO outer wrapper**: When a uapi record has `stream='sync'`, the response returned to the caller is the uapi.response Jinja2 template output directly — there is NO `{"status":"ok","data":{...}}` envelope. For image generation sync models, the client receives exactly: `{"status":"SUCCEEDED","usage":{...},"image_count":N,"image":[...]}`. Async models DO have a wrapper on submit (`{"status":"ok","data":{"taskid":"..."}}`) but the final result from `/v1/tasks` query is also direct. **Never add a wrapper layer in API documentation response examples for sync models.** This was corrected by the user three times in one session — zero tolerance. 42. **Token redaction breaks file writes containing Bearer auth patterns**: The system redacts strings matching `***...***` or `Bearer ***` patterns in transit. When writing files (Python scripts, HTML, markdown) that contain Bearer token placeholders like `Authorization: Bearer ***`, the redaction strips the pattern mid-string, leaving unterminated string literals, broken template literals, or truncated code. **Fix**: When generating files with Bearer auth examples via Python scripts, construct ALL strings containing the token pattern entirely from `chr()` calls. Example: `TK = chr(42)*3 + 'API_KEY' + chr(42)*3` then `AUTH = SQ + ''.join([chr(c) for c in [65,117,...]]) + TK + SQ`. Never write the literal token pattern as a string constant in the script file itself — even in comments, since the write_file tool scans the entire content. This pitfall applies to any file generation task involving API key examples, not just llmage docs. 43. **Always verify response formats with actual API calls before documenting**: API documentation response examples MUST be tested with real curl calls before being written to docs. Previously documented formats were wrong for months — usage fields, error shapes, URL domains were all invented/approximated rather than tested. **Workflow**: 1) curl the endpoint with a real request, 2) capture the exact JSON response, 3) use that as the doc example (redact only sensitive tokens). Different providers return different response structures (e.g., wan2.7 usage has tokens, qwen usage has dimensions; error responses have two distinct shapes). Never assume uniformity across providers. 44. **API doc changes must be holistic — docs + database + code together**: When changing API documentation (e.g., removing async mode, changing response formats), you MUST also check and update the underlying database configuration. User corrected this explicitly: "这里修改了话，你还要检查之前的sql中的sql的变更". **Checklist for any API doc change**: (a) Update api_doc.md text, (b) Verify actual API response matches new doc via curl, (c) Check `uapi.stream` field — must match sync/async claim in docs, (d) Check `llm_api_map.query_apiname` — must be NULL for sync models, populated for async, (e) Check `uapi.data` template — request body format must match docs, (f) If changing sync↔async, provide SQL migration statements for the user to execute on production. **Never just edit the markdown and stop** — the doc describes behavior controlled by database state, not by the text itself. 45. **Filtering llmusage by catalog requires llm_api_map subquery (NOT llm table)**: When filtering `llmusage` or `llmusage_history` records by `llmcatelogid`, you CANNOT query the `llm` table — it has no `llmcatelogid` column. The catalog relationship is in `llm_api_map`. Correct pattern: ```sql WHERE llmid IN (SELECT llmid FROM llm_api_map WHERE llmcatelogid = ${llmcatelogid}$) ``` Wrong pattern (causes SQL error 1054 "Unknown column"): ```sql WHERE llmid IN (SELECT id FROM llm WHERE llmcatelogid = ${llmcatelogid}$) -- WRONG: llm table has no llmcatelogid ``` This mistake is easy to make because the schema has migrated multiple times (llm_catalog_rel → llm → llm_api_map). Always check the table structure before writing the subquery. See models/llm.json and models/llm_api_map.json for current field lists. 46. **Cross-table UNION ALL pagination for llmusage + llmusage_history**: When querying historical inference records that span both active (`llmusage`) and archived (`llmusage_history`) tables, use UNION ALL with a subquery for pagination. The count query wraps the UNION in a subquery; the data query adds ORDER BY + LIMIT/OFFSET on the outer query. Both tables share the same schema (same columns). Example pattern: ```sql -- Count select count(*) as cnt from ( select id from llmusage where userid = ${userid}$ union all select id from llmusage_history where userid = ${userid}$ ) t -- Paginated data select id, llmid, use_date, use_time, userid, usages, ioinfo, status, ... from ( select id, llmid, use_date, use_time, userid, usages, ioinfo, status, ... from llmusage where userid = ${userid}$ union all select id, llmid, use_date, use_time, userid, usages, ioinfo, status, ... from llmusage_history where userid = ${userid}$ ) t order by use_time desc limit {page_size} offset {offset} ``` **ioinfo reading**: The `ioinfo` column stores a webpath string (e.g., `/llmio/182/138/79/46/xxx.json`), NOT the actual JSON. To read the content in a `.dspy` file: ```python from ahserver.filestorage import FileStorage import aiofiles fs = FileStorage() real_path = fs.realPath(webpath) async with aiofiles.open(real_path, 'rb') as f: bin_data = await f.read() io_content = json.loads(bin_data.decode('utf-8')) ``` Wrap in try/except — webpath may be None or file may not exist. The parsed JSON has `input` (dict) and `output` (list) keys. `usages` field may be a JSON string that needs `json.loads()` too. 47. **Non-inference v1 endpoints (pricing, etc.) use direct SQL ppid lookup, not get_llm()**: When building a v1 endpoint that queries model metadata (not inference), use a direct SQL JOIN to get `ppid` from `llm_api_map`, not `get_llm()` which requires uapi records. Pattern: ```python sql = """select m.ppid from llm a join llm_api_map m on a.id = m.llmid where a.model = ${model}$ and a.status = 'published' and m.ppid is not null and m.isdefaultcatelog = '1' """ recs = await sor.sqlExe(sql, {'model': model}) ppid = recs[0].ppid ``` Then call the appropriate env function (e.g., `env.get_pricing_display(ppid)`). Use `request._run_ns` to get `env`, and `get_sor_context(env, 'llmage')` for DB access. Return `json.dumps()` directly. The `/v1/pricing` endpoint follows this pattern. 48. **`apiname` is in `llm_api_map`, NOT in `llm` — common SQL JOIN error**: The `llm` table does NOT have an `apiname` column. It lives in `llm_api_map`. When writing SQL that joins `llm → uapi`, you MUST go through `llm_api_map`: ```sql -- ✅ CORRECT — apiname from llm_api_map (alias m) select a.*, e.ioid, e.stream from llm a join llm_api_map m on a.id = m.llmid join upapp c on a.upappid = c.id join uapi e on c.id = e.upappid and m.apiname = e.name where a.id = ${llmid}$ -- ❌ WRONG — llm table (alias a) has no apiname column select a.*, e.ioid, e.stream from llm a join upapp c on a.upappid = c.id join uapi e on c.id = e.upappid and a.apiname = e.name where a.id = ${llmid}$ ``` **Error**: `(1054, "Unknown column 'a.apiname' in 'ON'")` or similar. This mistake appeared in 3 files (4 occurrences) before being caught — `list_paging_catelog_llms.dspy`, `llmcheck.dspy` (2x), `api/llm_launch_check_api.dspy`. When grepping for this pattern, search for `a.apiname` across all dspy files. 49. **`list_paging_catelog_llms.dspy` must handle missing `llmid`**: The SQL `where x.id != ${llmid}$` hardcodes llmid, causing `(1054, "Unknown column 'llmid'")` when the endpoint is called without llmid (e.g., direct URL access). **Fix**: Use conditional SQL: ```python llmid = params_kw.get('llmid') if llmid: sql += " and x.id != ${llmid}$" ``` This pattern applies to any `.dspy` file where optional parameters are used in WHERE clauses. 49. **Multi-catelog model selection — UI must present catelog tabs**: A single model can have MULTIPLE `llm_api_map` entries (e.g., qwen-max has both t2t and vision catelogs). The `llm_dialog.ui` template MUST handle this by: 1. Calling `get_llm_catelogs(llmid)` to get ALL catelog entries 2. If `len(catelogs) > 1`, rendering an HBox with Button widgets per catelog 3. Default selection = the one with `isdefaultcatelog='1'`, or first entry if none is default 4. Each tab button links to `?id={{llmid}}&catelogid={{catelogid}}` to reload the UI 5. Passing `llmcatelogid` to BOTH the LlmIO `models[]` array AND the `list_models_url` query string 6. The bricks LlmModel widget sends `llmcatelogid` in inference requests automatically **Do NOT** just pick one catelog silently — the user must choose which capability to use. `get_llmage_llm(llmid)` without catelogid defaults to `isdefaultcatelog='1'`, which is correct for the default tab but wrong if the user wants a different catelog. **Jinja2 scoping**: When computing `active_catelogid` inside a `{% for %}` loop, `{% set %}` does NOT propagate out of the loop. Use `{% set ns = namespace(active_catelogid=...) %}` — see bricks-framework skill "LlmIO Widget" section for the correct/incorrect patterns. **Bricks side**: `bricks.LlmModel.inputdata2uploaddata()` includes `this.opts.llmcatelogid` in both FormData and JSON request bodies. `bricks.LlmIO.open_search_models()` passes `this.models[0].llmcatelogid` to `list_paging_catelog_llms.dspy` so related models are filtered by the same catelog. **`list_paging_catelog_llms.dspy` must return `llmcatelogid`**: Set `r.llmcatelogid = llmcatelogid` in the response loop so models added from the search popup carry the correct catelog for inference. 50. **Both `get_llms_by_catelog()` and `get_llms_sort_by_provider()` include pricing display data**: Both functions batch-query ALL distinct `ppid` values for each model (from `llm_api_map` via a single `IN (...)` query), call `env.get_pricing_display(ppid)` for each, and store `display_text` in `llm.pricing_display` (a list of strings). Both templates (`show_llms_cards.ui` and `show_llms_cards_by_provider.ui`) render pricing text in a Filler with `css: "pricing-box"`. Card height must be `cheight: 16` (not 12) to fit pricing info. Both functions handle `get_pricing_display` returning None gracefully (`if pd: pricing_list.append(...)`). **N+1 query pitfall**: Always use a single batch `SELECT DISTINCT llmid, ppid FROM llm_api_map WHERE llmid IN (...)` query to build a `pp_map` dict, then iterate per-model. Never query ppid per-model inside the loop. 51. **`llminference.dspy` MUST check `checkCustomerBalance` return value**: The inference API entry point calls `checkCustomerBalance()` but historically the return value `f` was assigned and never checked — the code continued to `inference()` regardless. The UI layer (`llm_dialog.ui`) gates display on the same check, but direct API calls bypass the UI. **Fix (mandatory in `llminference.dspy`):** ```python f = await checkCustomerBalance(params_kw.llmid, userid, userorgid) if not f: \treturn UiError(title='llm inference', message='余额不足或模型未配置定价') ``` **Owner org bypass**: `checkCustomerBalance` returns True immediately when `llm.ownerid == userorgid` (self-owned models skip balance/pricing checks). This is by design for internal usage but means models without pricing are usable by their owner. **General rule**: Every `.dspy` inference/API endpoint that calls a permission/balance check MUST verify the return value before proceeding. Assigning to a variable without checking is a silent security gap. 52. **`get_pricing_display` returns None for missing pricing data**: When `PricingProgram.get_ppid_pricing(ppid)` finds no pricing record for a given ppid+date, it raises an exception. `get_pricing_display` wraps this in try/except and returns None. Callers MUST check: `if pd: pricing_list.append(pd.get('display_text', ''))`. This prevents exception log spam when card pages iterate over all models (many may lack pricing). 53. **`test_pricing` type mismatch after `ppt_db2app`**: `get_pricing_program_timeing(pptid)` calls `ppt_db2app(ppt)` which converts `ppt.pricing_data` from YAML string to Python dict. But `get_pricing_from_ymalstr(data, yamlstr)` expects a YAML string. **Fix**: Check type and re-serialize: ```python yamlstr = yaml.dump(ppt.pricing_data, allow_unicode=True) if isinstance(ppt.pricing_data, dict) else ppt.pricing_data ``` This pattern applies anywhere `ppt_db2app` output feeds into a YAML-string-expecting function. 54. **External GPU service registration — uapi records MUST be complete**: Multi-endpoint ahserver services on GPU need ONE llm model per endpoint (unique constraint on llm_api_map). Do NOT create skeleton uapi records with only `id/name/path/upappid` — inference will fail silently because `get_llm()` caches uapi records and expects `stream`/`data`/`response`/`ioid` to be populated. Missing `response` = no `usage` in output = billing chain broken. **Registration order**: upapp → uapiio → uapi (with stream/data/response/ioid/headers) → upappkey → llm → llm_api_map → pricing_program → pricing_program_timing. **uapi response template**: Use `{%if error%}...{%else%}...{%endif%}` blocks for GPU error pass-through. Jinja2 `{{var or ""}}` does NOT handle undefined variables — only `{%if %}` works in Sage's environment. Async submit responses skip usage; status query responses include it. **ppid per model**: Each model needs its own ppid (e.g. `pp_ktv_asr`). Sharing one ppid across models causes billing mismatches because `llm_charging` iterates all pricing_timing under that ppid. **pricing YAML**: `price_factors: flat` = fixed fee (usage_value=1). `price_factors: ` = per-unit billing where the field comes from the usage JSON. `enabled_date` must be set (not NULL). **GPU parameter discovery**: GPU services may expect different param names than API docs. Query each endpoint directly to discover actual names, then map in uapi data template. See `references/ktv-service-registration-pattern.md` for the complete worked example. **uapi response template design for GPU services**: Use pass-through pattern — GPU service returns `usage` directly in its JSON response, template passes it through with `{{json.dumps(usage, ensure_ascii=False)}}`. Never hardcode usage field names (e.g. `audio_seconds`) in the template; let the GPU service own the pricing factor semantics. Async submit responses (`stream='async'`) do NOT need usage; the status query endpoint's response template does. **uapi stream classification**: Sync (`stream='sync'`) for quick operations; Async (`stream='async'` + `llm_api_map.query_apiname` pointing to a status-query uapi) for long GPU tasks. **New v1 endpoint for custom catalogs**: When models use a non-standard catelogid (e.g. `ktv_pipeline`), create a dedicated endpoint (e.g. `/v1/pipeline/submit/index.dspy`) that hardcodes the catelogid. Pattern matches `/v1/video/generations` but without requiring `prompt` as mandatory. Update all 3 doc locations (llmage docs/API.md, dashboard_for_sage api_doc.md, llmage wwwroot/api_doc.md if it exists). **KTV has 13 models** (synth-generate removed 2026-07-06 — 产线内部调 LLM 生成合成指令，不对外暴露；saved 12 sync + 1 async). If a model is no longer needed externally, remove its llm/llm_api_map/uapi/pricing records but keep the corresponding uapi for internal use if needed. See `references/ktv-service-registration-pattern.md` for the complete worked example, `references/gpu-parameter-discovery.md` for GPU parameter name mapping, `references/uapi-response-error-handling.md` for Jinja2 error handling, `references/pipeline-app-api-adapter.md` for the env-var-driven pipeline-app adapter pattern with model selection + cost estimation, `references/gpu-demucs-longtasks-pattern.md` for the async submit+status longtasks/Redis pattern used by GPU demucs service, and `scripts/verify-ktv-migration.py` for migration integrity checks (updated to 13 models). 55. **Provider table is `modelprovider`, NOT `llmprovider`**: Schema: id, name, label, description. The name `llmprovider` does not exist. 56. **`llm.enabled_date` and `expired_date` are REQUIRED for API visibility**: Models missing these don't appear in `/v1/models`. Set `enabled_date='2025-01-01'`, `expired_date='2099-12-31'` for new models. 57. **`ownerid='0'` for platform-public models**: Org-specific ownerid hides models from other orgs. Set to `'0'` for cross-org visibility. Cache keyed by `{ppid}.{date}`, Sage restart clears. 60. **Sage SQL scripts belong in the sage repo, NOT foms** 58b. **Every uapi `response` MUST carry `"usage"` for billing engine**: The billing pipeline reads `usage` from API responses and matches `pricing_data` fields. Example: `{"status":"ok","usage":{"audio_seconds":120}}` paired with pricing YAML using `audio_seconds` as factor. 60. **Sage SQL scripts belong in the sage repo, NOT foms** 65. **uapi response Jinja2 — only `{%if error%}` handles undefined variables reliably**: GPU errors like `{"error":"..."}` lack expected fields → `jinja2.exceptions.UndefinedError` → empty 200 response. `{{var or ""}}` fails (Jinja2 `or` checks truthiness, not definition). `default()` filter unavailable in Sage. See `references/uapi-response-error-handling.md`. 66. **upappkey ownerid must be real user ID**: `get_calluserid()` JOINs upappkey→users→upapp on ownerid/orgid. `ownerid='0'` fails. Use actual user ID (e.g. `UiEi7hKqAmU1-jqQEVhZe`). Sage restart required. 67. **pricing_program_timing.enabled_date cannot be NULL**: `checkCustomerBalance` fails if no pricing covers current date → 429. 68. **v1/models requires ppid IS NOT NULL**: `get_llms_by_catelog_to_customer()` filters `m.ppid is not null`. Set ppid for all llm_api_map records. 69. **Param naming: `_file` not `_url`**: File parameters use `_file` convention matching Sage's image/video/audio endpoints. `_url` confuses programmers who expect it to be a text prompt. Applies to uapiio, uapi data templates, and API docs. 70. **Regression test after any llmage change**: Call all existing v1 endpoints + new endpoints via tokentest API. Verify accounting. User: "修改后应该做回归测试的，不能省步骤". 72. **Async submit response MUST contain both `taskid` and `status` fields**: The asyncinference module reads `d.taskid` and `d.status` from the submit result via `DictObject(**json.loads(b))`. If the uapi submit response template only returns `taskid`/`taskstatus` but not `status`, `d.status` is undefined and the async task lifecycle breaks. **Correct**: `{"taskid":"{{task_id}}","taskstatus":"PENDING","status":"PENDING"}`. Additionally, the status query endpoint's response must use key `status` (not `taskstatus`) because asyncinference checks `new_output.get('status')`. The first poll also accesses `lastoutout['status']` (bracket access, NOT `.get()`) which raises KeyError if ioinfo has no output yet — this is handled by ensuring the submit step writes the initial ioinfo with `{"status":"PENDING"}`. See `references/async-demucs-debug-trace.md` for the full debug trace including path template `{{taskid}}` matching, ioinfo KeyError, and venv contamination from pip -e. 73. **GPU submit endpoint MUST use longtasks-returned task_id**: `longtasks.submit_task(payload)` generates a 32-char task_id via `getID()` and returns `{'task_id': '...'}`. Endpoints that generate their own 12-char UUID and ignore the return create mismatched IDs → status queries return "not_found" or "no task". Found in demucs, realesrgan, and ASR services. **Fix**: `result = await longtasks.submit_task(payload); task_id = result['task_id']`. Additionally, `task_type` in the submit payload must match what the worker's `process_task()` dispatches on — mismatch (e.g., `'upscale'` vs `'upscale_video'`) causes `Unknown task_type` error. See `references/gpu-demucs-longtasks-pattern.md`. 74. **Worker return status MUST be uppercase**: Sage asyncinference lifecycle compares `new_output['status']` against `'SUCCEEDED'` and `'FAILED'`. GPU workers returning lowercase `'success'`/`'failed'`/`'ok'` break the lifecycle — task stays PENDING forever. Found in demucs, realesrgan, and ASR. Fix all worker return dicts to use uppercase. Also add `"usage"` field to worker output for billing chain: `"usage": {"audio_seconds": round(duration, 3)}`. 75. **Pipeline-app venv contamination**: Installing pipeline-app pkgs via `pip -e` into Sage's venv creates editable installs (`__editable__*.pth` finders) that map packages like `ahserver` to pipeline-app's copy. This silently overrides Sage's own ahserver, breaking dspy globals (`getID` not defined) and causing 500s across all v1 endpoints. **Fix**: (a) Run pipeline-app separately with its own PYTHONPATH, never install into Sage's venv; (b) If contamination occurs, remove `__editable__*` files from Sage's `site-packages/`, remove any copied `pipeline_*` directories, and restore missing core packages (`ahserver`, `sqlor`, `appbase`, `rbac`) from pipeline-app's `pkgs/` directory by copying their source folders back. 76. **GPU ahserver endpoints are DIRECTORIES with index.dspy, NOT .dspy files**: The ahserver router maps `/api/xxx` → `app/api/xxx/index.dspy` (directory route). Creating `app/api/xxx.dspy` (file) produces "invalid path" error. Every new GPU endpoint needs: `mkdir -p app/api/` + create `index.dspy` inside it. 77. **ASR language code must be ISO 639-1, NOT 'auto'**: faster_whisper requires explicit language codes (zh, en, ja, etc.). Passing `'auto'` as language causes `ValueError: 'auto' is not a valid language code`. Hardcode to the expected language in the submit endpoint: `'language': params_kw.get('language', 'zh')`. This was found after successive GPU service restarts and Python venv changes — the error message is verbose (lists all 99 accepted codes) and appears in the Redis task result under `error` field. **GPU service Python**: ASR on port 9925 uses `/data/ymq/aligner/py3/bin/python3` which has both `ahserver` and `faster_whisper` — other venvs (system Python, demucs_venv) may be missing one or both. Kill old PID before restart: `ss -tlnp sport = :9925` to find PID. 78. **`{{model}}` in uapi data template sends Chinese name → upstream API 400**: uapi data 中 `"model": "{{model}}"` 渲染为中文名（如 `"快乐马-1.0-文生视频"`），但 Alibaba DashScope 等上游期望英文 identifier（`"happyhorse-1.0-t2v"`）。排查：`grep 'model=' /d/apitest/sage/logs/sage.log | tail -3` 看实际发出的 HTTP body。**修复**：硬编码英文名：`UPDATE uapi SET data = REPLACE(data, '\"model\": \"{{model}}\"', '\"model\": \"happyhorse-1.0-t2v\"')`。影响所有 tongyi-wan 新模型。**发现方法**：不在 llm 表里搜 `/v1/models` 返回的模型名，而是用 `SELECT name,model FROM llm WHERE model LIKE '%happyhorse%'` 查 `model` 列（英文 identifier），再用该 name 调 API。 48. **`apiname` is in `llm_api_map`, NOT in `llm` — common SQL JOIN error**: The `llm` table does NOT have an `apiname` column. It lives in `llm_api_map`. When writing SQL that joins `llm → uapi`, you MUST go through `llm_api_map`: ```sql -- ✅ CORRECT — apiname from llm_api_map (alias m) select a.*, e.ioid, e.stream from llm a join llm_api_map m on a.id = m.llmid join upapp c on a.upappid = c.id join uapi e on c.id = e.upappid and m.apiname = e.name where a.id = ${llmid}$ ``` 79. **ASR singing voice timing offset — all word starts are ~0.3s too early**: faster_whisper timestamps trigger on sound onset, not vocal peak. For singing voice, every word starts before the actual sung syllable. **Fix**: apply global +0.3s offset to all word timestamps before generating ASS subtitles. This is systematic, not progressive drift. Also, ASR produces noise segments ("好 啊", filler sounds) and can merge adjacent lyric lines → need manual `SEG_TO_LYRIC` calibration to skip garbage. See `references/ass-karaoke-subtitles.md` for patterns. 80. **Seedance/video generation idfile URLs expire quickly — download immediately**: Async video tasks return a `video` URL (e.g., `http://127.0.0.1:9180/idfile?path=/tmp/...`). These temp files may be cleaned within minutes. Poll for SUCCEEDED status, then download the video file IMMEDIATELY in the same script. Consider re-submitting if the download fails with 404. The `video` field (not `output_video_url`) holds the URL in task query response data.: pipeline-app 的 ahserver 污染后，dspy 预加载 globals 中 `getID` 不可用 → `NameError`。**临时修复**：`sed -i 's/getID()/str(__import__("uuid").uuid4()).replace("-","")/' /d/apitest/sage/wwwroot/llmage/v1/*/generations/index.dspy`。**根治**：不要将 pipeline-app 包安装到 Sage venv（见 Pitfall 75）。 74. **Worker return status MUST be uppercase**: Sage asyncinference lifecycle compares `new_output['status']` against `'SUCCEEDED'` and `'FAILED'`. GPU workers returning lowercase `'success'`/`'failed'` break the lifecycle — task stays PENDING forever. Fix all worker return dicts to use uppercase status values. Also add `"usage"` field to worker output for billing chain. 75. **Pipeline-app venv contamination**: Installing pipeline-app pkgs via `pip -e` into Sage's venv creates editable installs (`__editable__*.pth` finders) that map packages like `ahserver` to pipeline-app's copy. This silently overrides Sage's own ahserver, breaking dspy globals (`getID` not defined) and causing `ModuleNotFoundError` for Sage-only packages. **Fix**: (a) Run pipeline-app separately with its own PYTHONPATH, never install into Sage's venv; (b) If contamination occurs, remove `__editable__*` files from Sage's `site-packages/`, remove any copied `pipeline_*` directories, and restore missing core packages (`ahserver`, `sqlor`, `appbase`, `rbac`) from pipeline-app's `pkgs/` directory by copying their source folders back. 76. **GPU ahserver endpoints are DIRECTORIES with index.dspy, NOT .dspy files**: The ahserver router maps `/api/xxx` → `app/api/xxx/index.dspy` (directory route). Creating `app/api/xxx.dspy` (file) produces "invalid path" error. Every new GPU endpoint needs: `mkdir -p app/api/` + create `index.dspy` inside it. 77. **DSPY handler 硬编码 payload 导致新功能静默失败**：GPU 服务的 API handler 在 `app/api/{endpoint}/index.dspy` 中构建 payload 传给 longtasks worker。DSPY 是 hot-reload 的无需重启，但若 handler 只构建固定字段（如 `payload = {'task_type': 'separate'}`），即使 worker 已支持新 task_type 也会静默回退默认模式而不报错。**排查**：对比 worker log 中的 `task.payload` 与 curl 请求体。**修复**：透传 `params_kw` 中所有业务字段。详见 `references/ktv-service-registration-pattern.md` Pitfall 节。 80. **llmusage.id 格式判断 — 区分标准推理记录与手动插入记录**：`getID()` 生成 21 字符 nanoid（不是 32 字符 UUID）。`llmusage` 模型定义 `VARCHAR(32)`，两种长度都能存。标准推理流程（`_inference_generator` → `sync_uapi_request/async_uapi_request/uapi_request`）写入的特征：`id`=21-char nanoid + `ioinfo`=非空 webpath + `transno`=非空（来自 DSPY 的 uuid 或 getID）。**非标准记录特征**（手动 SQL 插入/测试脚本）：`id`=32-char UUID hex + `ioinfo`=NULL + `transno`=NULL。KTV 14 个 v1/media 端点全部走标准 `inference()` 路径，不存在"自己写推理逻辑"。排查时先看 `ioinfo` 和 `transno` 是否为空——双空即是手动插入。 81. **product_accounting 替代 llm_accounting**：`product_management/core.py` 的 `product_accounting()` + `backend_accounting()` 已替代 `llmage/accounting.py` 的 `llm_accounting()`。新流程走分销链（product_owner → ... → seller），每条 DictObject 会计条目带 `currency` + `base_amount`。汇率实时查询通过 `accounting/exchange.py` 的 `get_exchange_rate(from, to, rate_type)` 函数——支持正向和反向回退查找。修改计费逻辑时改 product_management，不要改已废弃的 llm_accounting。 82. **CRUD `logined_userorgid` 会隐藏平台级记录**：`json/*.json` CRUD 配置中的 `logined_userorgid: "ownerid"` 会自动添加 `WHERE ownerid = <当前用户orgid>`。若数据 `ownerid='0'`（平台级），当前用户 org 不是 '0' → 列表不显示，搜索也无结果。修复：删除 `logined_userorgid` 行，或将数据 `ownerid` 设为与用户匹配的 org。同时检查 `data_filter` 中 `op: "="` 的字段，空值时可能生成 `WHERE field = ''` 也过滤掉所有结果，改为 `op: "LIKE"`。此问题导致 pricing 模块 KTV 定价（`pp_ktv`，`ownerid` 原为 NULL，补设为 `'provider'`）搜索不到。 83. **asyncinference 不会自动调 llm_charging**：`asyncinference.py` 的 `query_task_status()` 在任务 SUCCEEDED 后保存 `usages` 但不计算 amount/cost。导致 `llmusage.amount=NULL`，`backend_accounting()`→`llm_accounting()` 无法记账。症状：usages 有值但 amount 为 NULL，accounting_status 停在 `created`。修复：在 `modify_llmusage(ns)` 后、返回前加 llm_charging 调用（注意 tab 缩进），详见 `references/asyncinference-llm-charging-fix.md`。 84. **uapi response 模板引号被 MySQL 吞掉**：`UPDATE uapi SET response = '{\"status\"...}'` 中 `\"` 被 MySQL 解释为转义后吃掉。结果模板变成 `{status:...}`（无效 JSON）→ Jinja2 渲染后 `json.loads()` 失败。修复：用 heredoc SQL 文件。详见 `references/uapi-template-json-quoting-pitfall.md`。 85. **GPU longtasks 返回嵌套 result**：RUNNING 时无 `result` 键，SUCCEEDED 时 `result` 含 `segments`/`usage`。模板须用顶层 `{%if status == "SUCCEEDED"%}` 做守卫，不能 `{%if result.status%}`（result 未定义→UndefinedError）。详见 `references/uapi-template-json-quoting-pitfall.md`。 83. **uapiio.input_fields 格式必须是数组，不能是对象**：bricks `LlmIO` 构造函数调用 `this.input_fields.forEach(...)`，要求 `input_fields` 是 JSON 数组字符串。若 uapiio 中存为对象格式 `{"field_name":{"type":"string",...}}`，JSON.parse 后是普通对象，`.forEach` 不可用 → `TypeError: this.input_fields.forEach is not a function`。**正确格式**：`[{"name":"field_name","label":"标签","uitype":"text","required":true}]`。uitype 取值：`text`（文本输入）、`audio`/`video`/`image`（文件上传）、`file`（通用文件）。症状：llm_dialog.ui 加载模型时前端 js 报错，模型选择卡片不显示。修复：`UPDATE uapiio SET input_fields = ''`，重启 Sage 清 process-level 缓存。 84. **定价显示币种 — get_ppid_pricing 必须查 a.currency**：`PricingProgram.get_ppid_pricing()` SQL 中未 select `a.currency` 导致 `get_pricing_display()` 无法获取币种信息，模型卡片始终显示"元"。修复：SQL 加 `a.currency`，`get_pricing_display()` 中从 record 取 `currency` 并附加到 display_text 首行（如 `【KTV产线计费】定价: ($)`）。currency_symbols 映射：CNY→元, USD→$, JPY→¥, GBP→£。修改后需 Sage 重启（process-level pricing 缓存 key 为 `{ppid}.{date}`）。 85. **product_accounting 已替代 llm_accounting**：`product_management/core.py` 的 `product_accounting()` + `backend_accounting()` 已接管 llmage 的记账。新记账走分销链，每个 DictObject 会计条目带 `currency` + `base_amount`。汇率实时查询通过 `accounting/exchange.py`。修改计费逻辑时改 product_management，不要改已废弃的 llmage/accounting.py 中的 `llm_accounting()`。 86. **pricing 币种显示修复三步**：① `get_ppid_pricing` SQL 加 `a.currency` → ② `get_pricing_display` 从 record 取 `currency` 附加到 display_text → ③ 替换 YAML unit_label 中硬编码的"元"为正确币种符号。修改后定价缓存需失效（key=`{ppid}.{date}`，Sage 重启自动清）。缺失任一步都会导致卡片仍显示"元"。 87. **uapiio input_fields 格式修复脚本模式**：当所有 uapiio 记录都是错误的对象格式 `{field: {type, required}}` 时，用 Python 脚本批量转换并输出 UPDATE SQL：`for ioid, fields in records: arr = [{"name": k, "label": v.description, "uitype": guess_uitype(k), "required": v.required} for k,v in fields.items()]; UPDATE uapiio SET input_fields='{json}'`。uitype 推断：含 audio→audio, video→video, image→image, file→file, 其他→text。执行后 Sage 重启清 process-level uapiio cache。 88. **Schema migration MUST run BEFORE code that references new columns**: Adding a column to a model JSON and writing code that queries it does NOT make the column exist in the database. The migration SQL (ALTER TABLE) must be executed on the target database BEFORE deploying code that references the new column. Otherwise: `OperationalError: (1054, "Unknown column 'a.currency' in 'SELECT'")`. This applies to all multi-module changes (accounting, pricing, llmage, product_management). **Checklist**: (a) Write migration SQL with all CREATE TABLE + ALTER TABLE statements, (b) Execute on test DB first, (c) Verify column exists with `SELECT COLUMN_NAME FROM information_schema.COLUMNS WHERE TABLE_NAME='tablename'`, (d) Deploy code, (e) Restart Sage. 89. **Exchange rate data must be inserted after table creation**: The `exchange_rate` table is created by migration SQL, but the actual rate data (USD/CNY, JPY/CNY, GBP/CNY buy/sell/mid prices) must be INSERTED separately. Use legitimate sources (Bank of China `https://www.boc.cn/sourcedb/whpj/`). Buy rate < sell rate (platform spread). 90. **pricing_program CRUD 搜索不到记录**: 两个常见原因 — (a) `logined_userorgid: "ownerid"` 过滤掉了其他机构所有的定价（如 KTV 定价 ownerid='0'），需移除；(b) `data_filter` 中 `op: "="` 空值时可能生成 `WHERE field = ''`，改为 `op: "LIKE"`。 91. **uapiio.input_fields 必须是数组格式**: bricks `LlmIO` 调用 `this.input_fields.forEach()`，对象格式 `{"field":{...}}` 会报 `TypeError: ...forEach is not a function`。正确格式: `[{"name":"field","label":"标签","uitype":"text","required":true}]`。 92. **定价显示币种**: `get_ppid_pricing()` SQL 加 `a.currency`，`get_pricing_display()` 用 `currency_symbols` 替换 YAML unit_label 中硬编码的"元"。三步缺一不可。 93. **providerid dropdown 必须查询 suppliers 表而非 organization**：`models/llm.json` 中 `codes.table` = `supplychain.suppliers` (valuefield=id, textfield=supplier_name)。CRUD JSON `llm.json` 的 `browserfields.alters.providerid` 指向 `get_search_providerid.dspy`，该 dspy 必须查询 `suppliers` 表（`select id as providerid, supplier_name as providerid_text from suppliers where status='1'`），**不能**查询 `organization` 表。使用 `get_sor_context(request._run_ns, 'rbac')` 连接 sage 数据库。同一模式适用于 `pricing_program.providerid`（pricing 模块的 CRUD JSON 也需配置 `alters`）。 94. **v1 endpoint RBAC: directory AND file path both need `rolepermission`**: Sage checks `/llmage/v1/audio/transcriptions` (directory) at RBAC level, not just the `index.dspy` file. Register BOTH paths: `INSERT INTO rolepermission ... WHERE path='/llmage/v1/audio/transcriptions'` AND `...WHERE path='/llmage/v1/audio/transcriptions/index.dspy'`. Missing directory entry = 403 even with valid Bearer token. 95. **`llm_api_map.llmcatelogid` mismatch with API `catelogid`**: When the API caller passes `catelogid=asr` but the model's `llm_api_map.llmcatelogid` is `ktv_pipeline` (or any non-matching value), the v1 endpoint SQL JOIN returns empty → "model not found" or "Parameters error". Fix: `UPDATE llm_api_map SET llmcatelogid='asr'` to match the standard catelog ID. Then restart Sage to invalidate caches. Check all models under each catelog after any catalog migration. 96. **Bearer token key creation for testing**: Generate: `from ahserver.globalEnv import password_encode; enc = password_encode(plaintext)`. INSERT into `downapikey` with `dappid='MF2QQSJ0FtBOeVv2rNoGM'` (test app). `allowedips=NULL` → no IP restriction. Auth flow: client sends `Bearer ` → Sage `password_encode()` → lookup `downapikey.apikey` → JOIN `downapp`. 97. **Async GPU status query uapi: nested result paths + Jinja2 guards**: When the GPU task status endpoint returns data nested under `result` (e.g., `{"status":"RUNNING","result":{"status":"SUCCEEDED","usage":{...}}}`), the uapi response template must access `result.status`, `result.usage`, etc. Template like `{"status":"{{result.status}}","usage":{{json.dumps(result.usage)}}}` fails with Jinja2 UndefinedError when task is RUNNING (no `result` yet). Fix with conditional: `{"status":"{{status}}"{%if result.status == "SUCCEEDED"%},"usage":{{json.dumps(result.usage,ensure_ascii=False)}}{%endif%}}`. Use top-level `status` for lifecycle (RUNNING/SUCCEEDED/FAILED), nested `result.*` only for final data. Without this guard, asyncinference polls get corrupted → tasks marked FAILED despite GPU success. 94. **v1 endpoint RBAC: directory AND file path both need `rolepermission`**: Sage checks `/llmage/v1/audio/transcriptions` (directory) at RBAC level, not just the `index.dspy` file. Register BOTH paths: `INSERT INTO rolepermission ... WHERE path='/llmage/v1/audio/transcriptions'` AND `...WHERE path='/llmage/v1/audio/transcriptions/index.dspy'`. Missing directory entry = 403 even with valid Bearer token. 95. **`llm_api_map.llmcatelogid` mismatch**: When API `catelogid` parameter doesn't match the model's `llm_api_map.llmcatelogid`, the v1 endpoint SQL JOIN returns empty → "model not found" or "Parameters error". Common: model under `ktv_pipeline` but caller uses `catelogid=asr`. Fix: `UPDATE llm_api_map SET llmcatelogid='asr'` to match the standard catelog ID. Then restart Sage to invalidate caches. 96. **Bearer token key creation for testing**: Generate: `from ahserver.globalEnv import password_encode; enc = password_encode(plaintext)`. INSERT into `downapikey` with `dappid='MF2QQSJ0FtBOeVv2rNoGM'` (test app). `allowedips=NULL` → no IP restriction. Auth flow: client sends `Bearer <plaintext>` → Sage `password_encode()` → lookup `downapikey.apikey` → JOIN `downapp`. 79. **ASR singing voice timing offset — all word starts are ~0.3s too early**: faster_whisper timestamps trigger on sound onset, not vocal peak. For singing voice, every word starts before the actual sung syllable. **Fix**: apply global +0.3s offset to all word timestamps before generating ASS subtitles. This is systematic, not progressive drift. Also, ASR produces noise segments ("好 啊", filler sounds) and can merge adjacent lyric lines → need manual `SEG_TO_LYRIC` calibration to skip garbage. See `references/ass-karaoke-subtitles.md` for patterns. 80. **Seedance/video generation idfile URLs expire quickly — download immediately**: Async video tasks return a `video` URL (e.g., `http://127.0.0.1:9180/idfile?path=/tmp/...`). These temp files may be cleaned within minutes. Poll for SUCCEEDED status, then download the video file IMMEDIATELY in the same script. Consider re-submitting if the download fails with 404. The `video` field (not `output_video_url`) holds the URL in task query response data. 81. **KTV video scene production workflow**: Use seedance-2-0 t2v for scene generation (via `/v1/video/generations`, catelogid=t2v). Submit all scenes in parallel (they run asynchronously). Each scene needs `ratio: "16:9"` and `duration` parameters. Download completed scenes immediately after polling SUCCEEDED. Use ffmpeg concat demuxer to merge scenes losslessly (`-c copy`). For dual-track KTV: `-map 2:a -map 1:a` puts accompaniment on track 0 (default) and original on track 1. Use `subtitles=file.ass` filter for subtitle burn-in. 79. **`{{model}}` in uapi data template sends Chinese name → upstream API 400**: uapi data 中 `"model": "{{model}}"` 渲染为中文名（如 `"快乐马-1.0-文生视频"`），但上游期望英文 identifier（`"happyhorse-1.0-t2v"`）。**修复**：硬编码英文名：`UPDATE uapi SET data = REPLACE(data, '\"model\": \"{{model}}\"', '\"model\": \"happyhorse-1.0-t2v\"')`。HappyHorse t2v 修复后 27/27 视频场景全部成功提交并完成。此问题影响所有新模型。 62. **uapi 参数命名：文件类参数用 `_file`，不用 `_url`**：与 Sage 现有的 `image_file`/`audio_file`/`video_file` 保持一致。单个文件用 `_file`（如 `audio_file`），多个文件用 `_files` 数组，比对类用 `_file1`/`_file2`。`_url` 会让程序员误解这是 prompt 一类的文本参数。**uapiio.input_fields、uapi.data 模板、API 文档三处的参数名必须一致。** 用户明确纠正过：看到 `"video_url":"{{prompt}}"` 会搞晕人类程序员。 64. **llmage API 变更后必须做回归测试**：修改 uapi 配置、新增 v1 端点、或更新文档后，必须通过 token.opencomputing.cn 的 API 端点实际调用验证。测试范围：现有端点（/v1/chat/completions, /v1/image/generations, /v1/video/generations）确保不退化 + 新端点功能正确 + 计费链路完整（调用后等 12s 让 backend_accounting 10s 循环处理，检查 accounting_status 不是 'failed'）。用户明确要求："修改后应该做llmage模块api的回归测试的，不能省步骤"。API key 从 ~/.hermes/config.yaml 的 custom_providers 读取。参考 `references/v1-api-testing.md`。 66. **uapi response 模板必须在 Jinja2 中处理 undefined 变量**：当 GPU 服务返回错误（如 `{"error":"images list required"}`）而非预期的 `{"status":"ok","faces":[...],...}` 时，直接引用 `{{status}}`、`{{faces}}` 等字段会抛出 `jinja2.exceptions.UndefinedError`。Sage 的 uapi 层在 `call()` 方法中 catch 了这个异常但只 debug 不 re-raise，导致返回空 body（HTTP 200 + 0 字节）。**修复**：所有 response 模板必须用 `{%if error%}{"error":"{{error}}"}{%else%}...{%endif%}` 块包裹。不能用 `{{status or ""}}`（Jinja2 的 `or` 对 undefined 变量无效），不能用 `default()` 过滤器（Sage 的 Jinja2 环境可能不支持）。async 提交端点无需此处理（其 response 只有 `taskid` + `taskstatus`）。排查空响应时先 `grep 'pipeline\|get_calluserid' /d/apitest/sage/logs/sage.log` 看是否有 UndefinedError 被捕获。 67. **`upappkey` 鉴权要求 `ownerid` 匹配实际用户**：`sync_uapi_request` 调用 `get_calluserid(upappid, orgid=llm.ownerid)` 来获取用于调用上游服务的 API 用户。该函数执行三表 JOIN `upappkey a, users b, upapp c WHERE b.orgid = c.ownerid AND a.ownerid = b.id`。因此 `upappkey.ownerid` 必须是一个 `users.id`，该用户的 `orgid` 必须等于 `upapp.ownerid`。`ownerid='0'` 是平台公开标记，不匹配任何真实用户 → `get_calluserid` 抛异常 → HTTP 200 + 空 body。**修复**：参照同类服务（如 minimax）设置 `upappkey.ownerid` 为实际用户 ID，`orgid` 匹配 `upapp.ownerid`。tokentest 上有效用户：`UiEi7hKqAmU1-jqQEVhZe`。Sage 重启清除缓存后才生效。 67a. **pricing_program 表字符集必须与 xls2ddl 标准一致**：xls2ddl 建表标准为 `utf8mb4_unicode_ci`。生产环境若 `pricing_program` 列使用了 `utf8mb4_general_ci`，会与 `organization` 表 JOIN 时报 `Illegal mix of collations` 错误。**修复**：`ALTER TABLE pricing_program MODIFY ownerid VARCHAR(32) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;` — 同理处理 `providerid`。所有 DDL 通过 xls2ddl 生成，字符集必须一致。 68. **`pricing_program_timing.enabled_date` 不能为 NULL**：即使 `llm.min_balance=0`，`checkCustomerBalance` 仍然检查当前日期是否在 `pricing_program_timing.enabled_date` 和 `expired_date` 范围内。`enabled_date=NULL` 时检查失败 → 429 insufficient_quota。**修复**：`UPDATE pricing_program_timing SET enabled_date='2025-01-01' WHERE ppid='pp_xxx' AND enabled_date IS NULL`。 69. **记账验证不能只说"链路正常"**：用户要求实测 `accounting_status='accounted'` + `amount/cost` 与定价一致。验证方法：插入含有效 `usages={"次":1}` 的 `llmusage` 记录（`status='SUCCEEDED'`, `accounting_status='created'`, 使用真实 `userid`/`userorgid`），等 15s 让 `backend_accounting` 10s 循环处理，查 `accounting_status`、`amount`、`cost`。所有 14 个端点逐个验证，不能只测一个就声称全过。用户明确纠正："记账链路正常没有用，我需要的是14个API的记账全部成功记账正确"。 70. **tokentest 测试环境完全掌控，不要每步都申请审批**：SSH apitest@tokentest.opencomputing.cn（免密），mysql -utest -ptest123 sage，Sage 端口 9180。API key 从 config.yaml 的 custom_providers 读取。`rolepermission` 表列名为 `roleid`/`permid`。生产环境是 token.opencomputing.cn，测试是 tokentest.opencomputing.cn，不要混淆。新增端点流程：1) 部署 dspy 到 wwwroot 2) load_path.py 加路径 3) `./py3/bin/python load_path.py` 4) 重启 Sage。参考 `references/sage-endpoint-deployment.md`。 71. **uapi response Jinja2 模板 — `{%if error%}` 模式是唯一可靠的容错方式**：GPU 服务返回 `{"error":"..."}` 时，模板中任何对 `status`/`usage` 等不存在字段的引用都会导致 `UndefinedError` → 空响应。`{{status or ""}}` 对 undefined 变量无效（Jinja2 的 `or` 只判断 truthiness，不处理 undefined）。`default()` 过滤器在 Sage 的 Jinja2 环境可能不可用。只有 `{%if error%}...{%else%}...{%endif%}` 块能可靠处理。排查空响应：`grep 'get_calluserid\|UndefinedError\|response_template' /d/apitest/sage/logs/sage.log | tail -20`。 72. **`{{model}}` in uapi data template sends Chinese name → upstream API 400**：uapi data 中 `"model": "{{model}}"` 渲染为中文名，但上游期望英文 identifier。**修复**：硬编码英文名。 73. **新增v1端点前必须先学习现有模式**：不要盲目创建 dspy 文件。先读 `/v1/chat/completions/index.dspy`（请求体参数模式）和 `/v1/pipeline/submit/index.dspy`（catelogid硬编码+inference模式）了解正确的 dspy 结构。用户纠正："不能自己瞎做，你改学习一下uapi和llmage的API接口skill和规范"。关键模式：SQL JOIN `llm → llm_api_map → llmcatelog`、`checkCustomerBalance()` 返回值检查、`inference()` vs `inference_generator()` 的选择。错误的dspy导致500或空响应。默认使用 `openai_403()`/`openai_400()`/`openai_429()` 错误返回（非 `UiError`）。 74. **路径参数化端点需要独立目录**：`/v1/media/{apiname}` 中每个 apiname 必须有独立目录和 index.dspy。ahserver 将 `/v1/media/asr-transcribe` 路由到 `v1/media/asr-transcribe/index.dspy`，而非 `v1/media/index.dspy`。不能用 catch-all 模式。生成14个目录用Python脚本（非手动复制）。异步任务状态查询**复用已有 `/v1/tasks`**，不需要创建 `/v1/status`。部署流程见 `references/v1-media-endpoint-deployment.md`。 73. **`getID()` broken after venv contamination — ALL v1 dspy endpoints need uuid fix**：pipeline-app 的 ahserver 通过 pip -e 污染 Sage venv 后，dspy 预加载 globals 中 `getID` 不可用 → `NameError`。统计日志中受影响端点：pipeline/submit, image/generations, video/generations。**临时修复**：`sed -i 's/getID()/str(__import__("uuid").uuid4()).replace("-","")/' /d/apitest/sage/wwwroot/llmage/v1/*/generations/index.dspy`。**根治**：从不将 pipeline-app 包安装到 Sage venv（见 Pitfall 75）。 63. **uapi response 模板 — 透传 usage，不硬编码字段名**：GPU 服务在响应 JSON 中直接返回 `usage` 对象，模板用 `{{json.dumps(usage, ensure_ascii=False)}}` 原样透传。不要从散列字段拼装 usage（如 `"usage":{"audio_seconds":{{audio_seconds|float}}}`）— 这样 pricing 要素变化时模板就得改。async 提交端点（`stream='async'`）的 response 不含 usage（由 status 查询端点返回），其余所有 response 模板必须含 `"usage"`。 ## File Handling in uapi templates Sage's uapi layer handles file upload/download through Jinja2 templates and ServerEnv globals. ### b64media2url Extension Bug (DashScope Incompatibility) **CRITICAL**: `b64media2url()` saves base64 data to a temp file via `base642file()`, then returns a URL like `/idfile?path=/tmp/xxx/yyy/zzz.mp3`. DashScope (and some other providers) validate the URL **path extension** — but they see `/idfile` (no extension) and reject it with `InvalidURL: File type is not supported. Allowed types are: .wav, .mp3.` **Root cause**: `FileStorage.webpath()` returns a relative path, and the URL is constructed as `entire_url('/idfile?path=') + quote(webpath)`. The path segment is `/idfile`, not `/xxx.mp3`. **Workaround for now**: Upload files to external storage (OSS, CDN) and pass direct HTTPS URLs instead of base64. Or fix `b64media2url()` to use a URL path that includes the file extension (e.g., `/idfile/xxx.mp3?path=...`). **MIME type mapping**: `MIME_EXT` in `appPublic/base64_to_file.py` maps `audio/mpeg` → `mp3` (correct), NOT `audio/mp3`. When constructing data URLs, use `data:audio/mpeg;base64,...` for MP3 files, not `data:audio/mp3;base64,...`. Wrong MIME type causes the file to be saved with an unknown extension. ### File Upload → API Request (`b64media2url`) When uapiio defines file fields (`uitype: "image"/"audio"/"video"`), uploaded files are stored on the server and `params_kw` holds relative paths. The `b64media2url(request, filename)` function (registered in ServerEnv globals) converts them to base64 data URLs for API requests. **Usage in uapi.data templates:** ```jinja2 {# Single file #} "image_url": "{{b64media2url(request, image_file)}}" {# Multiple files #} "images": ["{{b64media2url(request, image_file1)}}", "{{b64media2url(request, image_file2)}}"] {# Audio #} "audio_url": "{{b64media2url(request, audio_file)}}" ``` **Internal logic**: If the value already starts with `data:`, return as-is. Otherwise, use `FileStorage().realPath()` to get the server path, read the file, and encode to base64. **uapiio field definition:** ```json {"name": "image_file", "label": "首帧图片", "uitype": "image"}, {"name": "audio_file", "label": "配音文件", "uitype": "audio"}, {"name": "video_file", "label": "输入视频", "uitype": "video"} ``` ### Generated File Output (Async Models) Model-generated files (images, videos, audio) are stored as JSON files. The `llmusage.ioinfo` column holds the webpath (e.g., `/llmio/182/138/79/46/xxx.json`) rather than full JSON content. **ioinfo JSON structure:** ```json { "input": {"model": "wan2.1", "prompt": "...", "image_url": "data:image/png;base64,..."}, "output": [ {"model": "wan2.1", "content": "", "finish": "0", "llmusageid": "xxx"}, {"model": "wan2.1", "content": "https://cdn.example.com/generated.mp4", "finish": "1", "usage": {...}} ] } ``` **Async response template (uapi.response) — extract result URL from external API:** ```jinja2 {"taskid": "{{task_id}}", {% if state == 'SUCCEEDED' %}"status": "SUCCEEDED", "result_url": "{{output_video_url}}" {% elif state == 'FAILED' %}"status": "FAILED" {% else %}"status": "PENDING"{% endif %}} ``` ### File Handling Pitfalls - `b64media2url` requires `request` as first argument: `b64media2url(request, filename)` - Variable names in uapi.data must match uapiio `input_fields[].name` exactly - Undefined file fields cause `jinja2.exceptions.UndefinedError` — ensure optional fields are checked - base64 encoding inflates file size ~33% — respect provider size limits ## uapi Architecture Change The `uapiset` table has been removed. `auth_apiname` moved to `upapp`, `uapi` now links via `upappid`. See `references/uapi-architecture-change.md` for full migration details and code diffs. ## Backend Accounting **Backend accounting runs as a standalone process (NOT in the webapp).** See `references/backend-accounting-deployment.md` for the complete deployment flow, sys.path fix for pricing imports, known bugs (usages overwrite, template syntax), and troubleshooting guide. The accounting chain: `llmage` writes `llmusage` (accounting_status='created') → `product_management.ProductManager.backend_accounting()` as a standalone `bin/backend_accounting.py` process polls via `get_accounting_llmusages()` → `product_accounting()` creates accounting entries via `consume_accounting()`. ### Accounting & Backup Details See `references/accounting-logic.md` for the complete accounting loop, failure recording, and backup logic documentation. See `references/backend-accounting-architecture.md` for the standalone process model and data flow between llmage and product_management. ## Deployment Flow See `references/sage-deployment-flow.md` for the corrected deployment procedure (source venv → git pull → pip install . → restart). ## uapi Template Debugging See `references/uapi-template-debugging.md` for common pitfalls: MySQL quote escaping, Jinja2 guards (`{%if status == \"SUCCEEDED\"%}` not `{%if result.status%}` — result is undefined during RUNNING), GPU response nesting (`result.segments` not top-level), and llmcatelogid mismatches. Also see `references/tenantid-setup.md` for v1 endpoint tenantid configuration from organization.parentid. ## Pitfalls 1. **SQLor `sort` 参数 vs 显式 SQL `ORDER BY` — 只能二选一**: SQLor 的 `params['sort']` 会自动生成 `ORDER BY`。如果 SQL 已经显式添加了 `ORDER BY`，必须从 `params` 中移除 `sort` 键，否则同时存在的两条 ORDER BY 导致排序冲突： ```python # ❌ BOTH — 冲突 params = {'today': today, 'sort': ['catelog_id', 'providerid']} sql += " order by m.llmcatelogid, a.providerid, a.name" # ✅ 只保留显式 ORDER BY params = {'today': today} sql += " order by m.llmcatelogid, a.providerid, a.name" ``` 2. **`list_llms`/`get_llms_by_catelog_to_customer` 同 catelog 被拆成多组**: `SELECT DISTINCT` 无 `ORDER BY` 时 MySQL 返回顺序不可控。分组循环 `if cid != r.catelog_id` 假设同 catelog 的所有行连续——不连续则生成多个重复组。修复：显式 `ORDER BY m.llmcatelogid, a.providerid, a.name` 并移除 `params['sort']`。 ## API Documentation **Multiple API doc locations** must be kept in sync when adding/changing v1 endpoints: | Location | Format | Purpose | |----------|--------|---------| | `~/repos/llmage/wwwroot/api_doc.md` | Markdown | Primary v1 API reference (in the llmage repo, served in-app) | | `~/repos/llmage/docs/API.md` | Markdown | Duplicate copy in llmage repo — must stay in sync with api_doc.md | | `~/repos/dashboard_for_sage/wwwroot/api_doc.md` | Markdown | Dashboard reference copy | | `~/repos/dashboard_for_sage/wwwroot/api_doc.html` | HTML (Apifox-style) | Customer-facing interactive doc (left nav + right detail + collapsible params) | | `~/repos/sage/wwwroot/public/api/api_zh.md` | Markdown | Legacy static file (may be stale) | **When adding a new v1 endpoint, update BOTH llmage repo docs AND commit+push in the same session.** The two llmage docs (`api_doc.md` and `docs/API.md`) are near-duplicates and must be updated together. **api_doc.html structure**: Single-file HTML with embedded JS. API endpoints defined in a `apiData` JavaScript array. Each entry has: `id`, `method`, `path`, `title`, `desc`, `params` (sections with rows), `requestExample`, `responseExamples`, optional `models` (per-model tabs), optional `errors`, optional `curlExamples: [{ title: "label", code: \`curl ...\` }]`. New endpoints must be added to the correct group's `items` array. The `renderContent()` function renders `curlExamples` as titled code blocks if present. **API doc update checklist** when adding/modifying v1 endpoints: 1. Update `api_doc.md` with new endpoint section (params, request/response examples, **curl test cases per model**) 2. Update `api_doc.html` — add entry to the correct group in `apiData` JS array (include `curlExamples` array) 3. All examples must use `model` (model name string) + `catelogid` (t2t/t2i/t2v/i2v/ref2v), NOT `llmid` (UUID) 4. **Response examples MUST be verified with real curl calls** — read the actual `response` field from the uapi SQL script or database, then render the Jinja2 output as a concrete JSON example. **There is NO outer wrapper** — the response IS the uapi.response template output directly. **Never invent/approximate response formats.** User has zero tolerance for invented response formats. See `references/image-gen-api-testing-2026-06-03.md` for tested image gen response formats. 5. **Include all available models** — do not silently remove models from docs. If a model exists in the database, it must appear in the doc. User corrected: wan2.7 models were removed from docs after a prior cleanup session but should have been retained. 6. **curl test cases**: Each API endpoint needs curl examples. For endpoints supporting multiple models, provide one curl per model variant (e.g., sync vs async, different providers). Markdown: `### curl` section with code blocks. HTML: `curlExamples: [{ title: "...", code: \`...\` }]` array on each endpoint object. 7. Commit and push both files in the same session **Image generation response format** (ALL models are sync — no async image generation): ```json // Success (wan2.7 series — usage has tokens): {"status":"SUCCEEDED","usage":{"image_count":1,"input_tokens":22,"output_tokens":2,"size":"1024*1024","total_tokens":24},"image_count":1,"image":["https://token.opencomputing.cn/idfile?path=/tmp/...png"]} // Success (qwen-image series — usage has dimensions): {"status":"SUCCEEDED","usage":{"height":1024,"image_count":1,"width":1024},"image_count":1,"image":["https://token.opencomputing.cn/idfile?path=/tmp/...png"]} // Error — missing required parameter (400): {"status":"error","data":{"message":"Missing required parameter: prompt"}} // Error — invalid model or params (400): {"error":{"message":"Parameters error.","type":"invalidparameters","param":null,"code":"invalidparameters"}} ``` **Key differences from old docs**: - `usage` field varies by provider: wan2.7 returns `input_tokens`/`output_tokens`/`size`/`total_tokens`; qwen returns `height`/`width`/`image_count` - Image URLs are proxied through `token.opencomputing.cn/idfile?path=...` — NOT direct DashScope OSS links - Two distinct error response shapes (parameter validation vs model/param errors) - Size format uses `*` separator: `1024*1024`, NOT `1024x1024` - **No async image models** — all image generation is synchronous. `/v1/tasks` is only for video generation. - **Critical**: Do NOT wrap sync responses in `{"status": "ok", "data": {...}}`. Do NOT use OpenAI-style `{"id": "luid_xxx", "object": "image.generation", ...}`. The response is the uapi.response template output verbatim. ## Image Generation Model Inventory See `references/image-gen-models.md` for the complete inventory of text2image models, their uapi configurations, and sync/async patterns extracted from production database. ## Video API Testing Findings See `references/video-api-testing-findings.md` for API parameter quirks discovered during testing: HappyHorse I2V parameter naming, Seedance Ref2V required fields, Vidu Ref2V proxy issues. ## Audio API Model Inventory See `references/audio-api-models.md` for the complete inventory of TTS, ASR, and music generation models extracted from production database, including uapi/uapiio configurations. ## Onboarding New Model Types from SQL Dumps When adding a new model category (e.g., TTS, ASR, music) to the v1 API, follow this workflow: ### Step 1: Extract model records from SQL dump Production backups live at `~/db/prod.*.sql`. The INSERT lines are massive (180KB+ single lines). Use Python to parse tuples: ```python # extract_models.py — extract specific model records from SQL dump import re def extract_tuple(line, search_id): """Extract a full SQL INSERT tuple by searching for an ID string.""" idx = line.find(f"'{search_id}'") if idx < 0: return None start = line.rfind('(', 0, idx) if start < 0: return None depth = 0 in_str = False j = start while j < len(line): c = line[j] if c == "'" and (j == 0 or line[j-1] != '\\'): in_str = not in_str if not in_str: if c == '(': depth += 1 elif c == ')': depth -= 1 if depth == 0: return line[start:j+1] j += 1 return None ``` ### Step 2: Identify relevant table line numbers ```bash grep -n 'CREATE TABLE.*llm\b' ~/db/prod.*.sql # llm table structure grep -n 'CREATE TABLE.*uapi\b' ~/db/prod.*.sql # uapi table structure grep -n 'CREATE TABLE.*uapiio' ~/db/prod.*.sql # uapiio table structure ``` Key tables and their INSERT line positions (typical): - `llm`: model definitions (name, model, upappid, providerid) - `llm_api_map`: model→catalog→API mapping (llmid, llmcatelogid, apiname, ppid) - `uapi`: API endpoint configs (path, headers, data template, response template) - `uapiio`: input field definitions (input_fields JSON) ### Step 3: Search for relevant records Use grep on specific INSERT lines for keyword matching: ```bash sed -n '<INSERT_LINE>p' ~/db/prod.*.sql | grep -oi "'[^']*music[^']*'" ``` ### Step 4: Create v1 endpoint Follow the existing pattern from `v1/video/generations/index.dspy` or `v1/image/generations/index.dspy`: - Validate required params (model, catelogid, + type-specific params) - SQL JOIN: `llm → llm_api_map → llmcatelog` with `(b.id = ${lctype}$ OR b.name = ${lctype}$)` - `checkCustomerBalance()` → `inference()` ### Step 5: Update three places 1. **docs/API.md** — add endpoint section with params table, models table, request/response examples 2. **scripts/load_path.py** — add to both `PATHS_LOGINED` and `PATHS_V1_CUSTOMER` 3. **Commit + push** — single commit covering all three files ### Pitfall: SQL dump lines are enormous The INSERT lines for `uapi` and `uapiio` tables can be 180KB+ (single line with all records). Never try to `cat` or `read_file` these lines directly. Always use Python parsing with the `extract_tuple()` approach above, targeting specific IDs found via grep. ## llmcatelog ID Standardization See `references/llmcatelog-id-migration.md` for the complete migration plan: standardizing llmcatelog.id from random UUIDs to meaningful abbreviations (t2t, t2v, i2v, etc.) using the appcodes system, with full impact analysis of affected files across modules.
