| 素材 / Material | Uploaded source content referenced in prompts as @图片1, @视频1, @音频1. |
Uploads become assets under the authenticated owner. |
| Asset | Stored upload or generated result with metadata and owner scope. | Owner-scoped not-found behavior (404) is a compatibility contract. |
| Generation job / Task | Async unit of image or video generation: submit, claim, execute, poll provider, terminal transition, optional Webhook. | Claimed via claim_generation_jobs; idempotent per provider task id. |
| Wallet | Organization balance with immutable ledger entries. | Posted atomically via billing_post_wallet_entry; integer-fen arithmetic. |
| Ledger | Append-only record of wallet movements (charge, refund, settlement, adjustment). | Replayable for reconciliation. |
| Quote | Server-side estimate for a generation request using the matched billing rule and parameter tiers. | Preview is quote-only; submission is balance-gated. |
| Engine / Provider | External generation service: 即梦 (Jimeng), EvoLink GPT Image 2, Seedance 2.0, Bailian. | Adapters isolate provider payloads and status mapping. |
| Worker | Process that periodically calls the internal Worker tick endpoint to claim and execute jobs. | Node Worker has no RDS credentials; Go embeds a WorkerLoop after cutover. |
| WorkerLoop | Embedded async task loop inside the Go backend. | Replaces the HTTP-polling Node Worker only after drain and verification. |
| Cutover | Single-writer routing of /api, /uploads, /generated-results to Go, Node Worker drain, then Next Route Handler deletion. |
Must stay reversible; ACK-001 remains truth until it passes. |
| Contract fixture | Language-neutral JSON contract under contracts/ for HTTP, Cookie, auth, jobs, billing, storage, Webhook behavior. |
Executable by both TypeScript and Go consumers. |
