 | 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. |
+| Worker | Legacy Node process that polled an internal HTTP tick endpoint to claim and execute jobs. | No longer shipped or deployed in the accepted static Web + Go architecture. |
+| WorkerLoop | Embedded async task loop inside the Go backend. | The production job-execution path; it uses Go application/module seams without a Web tick endpoint. |
+| Static Web | Next.js static export (`out/`) served by unprivileged Nginx. | Has no SSR, Route Handlers, Middleware, runtime application configuration, database access, or session Secret. |
+| Cutover | Historical migration from Next-owned runtime routes and the Node Worker to Go-owned routes and WorkerLoop. | The first production rollout now deploys the static Web and Go revisions directly; no legacy drain sequence is required. |
 | Contract fixture | Language-neutral JSON contract under `contracts/` for HTTP, Cookie, auth, jobs, billing, storage, Webhook behavior. | Executable by both TypeScript and Go consumers. |
 | `zhinian_session` | Signed (HMAC-SHA256), chunked (3000 chars, up to 20 chunks) session cookie. | `HttpOnly`, `SameSite=Lax`, `Path=/`, production `Secure`. |
