+New Grok image and video generation requests use a media-specific eligibility check. API-key accounts remain eligible. OAuth accounts with explicit Free or forbidden billing evidence are excluded from new media generation. Missing or malformed observations are probed before dispatch; a successful but incomplete billing response is treated as `billing_inconclusive` and remains eligible for backwards compatibility, because an unknown billing schema is not proof that the account lacks media entitlement. Operators can quarantine a known-bad account with `extra.grok_media_eligible=false` or force-enable a verified account with `true`. Imports run the billing-first quota probe proactively. Chat requests and video status lookups are not affected by this media-only quarantine. If no eligible account remains, the media endpoint returns HTTP `503` with error type `grok_media_no_eligible_account`.
 
 Administrators can override automatic media eligibility through the account create/update API by setting `extra.grok_media_eligible` to `false` (exclude) or `true` (force eligible). On update, set it to `null` to remove the override and return to automatic probe-based behavior; omitting the field preserves the current override. A weekly allowance period alone is not treated as a paid tier signal. Successful image responses must contain at least one actual image output; empty HTTP `200` responses trigger account failover instead of being counted and returned as successful generations.

+## Codex Fast/Flex 策略说明
+
+管理员后台的 `系统设置 -> 网关服务 -> OpenAI Fast/Flex 策略` 只负责处理请求体中的 `service_tier`，不会修改 Codex 客户端的模型目录，也不会让 Codex UI 自动出现 Speed 或 `/fast` 选项。
+
+策略支持以下处理方式：
+
+- `pass`：保留客户端传入的 `service_tier`；`fast` 会规范为上游使用的 `priority`。
+- `filter`：移除 `service_tier`，按普通优先级请求。
+- `block`：拒绝匹配的 Fast/Flex 请求。
+- `force_priority`：将匹配请求强制设置为 `priority`，会按 Priority/Fast 价格计费。为避免升级后改变既有规则语义，`all` 只匹配显式存在的 tier；如需让省略 `service_tier` 的 OpenAI 请求也强制升级，必须新增 `service_tier=missing + force_priority` 规则。非 OpenAI 平台不会执行缺省 tier 注入。这种方式可以让请求实际使用 Fast，但 Codex UI 仍可能不显示 Fast 状态。
+
+Codex 的 Fast 入口由客户端模型目录驱动。只有当前模型目录声明了 `additional_speed_tiers: ["fast"]` 和对应的 `service_tiers`，Codex 才会显示 `/fast`。通过 API Key 或自定义模型提供商连接 Sub2API 时，如果模型目录没有这些字段，即使后台配置了 `force_priority`，重启 Codex 后也不会出现 Speed 选项。
+
+客户端可在 `~/.codex/config.toml` 中直接指定默认请求级别：
+
+```toml
+service_tier = "fast"
+
+[features]
+fast_mode = true
+```
+
+其中 `service_tier = "fast"` 会让请求携带 Fast 设置；`features.fast_mode` 只启用客户端 Fast 功能。模型目录没有声明 Fast 能力时，`/fast` 仍可能不显示。可通过 Sub2API 使用记录确认最终 `service_tier` 是否为 `priority`。

+
+OAuth / Setup Token 图片请求使用 Responses 主控模型调用 `image_generation` 工具，默认主控为 `gpt-5.6-luna`。可设置 `SUB2API_IMAGES_MAIN_MODEL` 切换为账号支持的文本模型；Docker Compose 用户修改 `.env` 后执行 `docker compose up -d` 重建容器。该配置不会替换所选图片模型，也不会覆盖 `/v1/responses` 请求中已经提供的文本主控模型。
+
+升级后，无模型限制的账号自动支持新模型。已有显式账号映射或分组白名单需要加入两个 2.5 模型（日期快照按需加入）；升级不会自动扩大管理员设置的模型权限。新模型内置价格包含官方文本输入、图片输入和图片输出 token 费率，远端价格表尚未更新时使用内置 2.5 价格；实际按次或按 token 计费仍由既有分组/渠道配置决定。

+# Upstream error proxy attribution
+
+## Scope
+
+Gateway inference errors are stored in `ops_error_logs.upstream_errors`. Each
+array item represents one upstream attempt, including same-account retries and
+cross-account failover attempts. Proxy attribution is stored on that item; it
+must not be reconstructed later from `accounts.proxy_id`.
+
+This repository has one gateway implementation under `backend/internal/service`.
+There is no separate `gateway/backend` source copy to synchronize.
+
+## Event contract
+
+Every newly persisted event contains these fields. `proxy_id` is emitted even
+when its value is JSON `null`:
+
+| Field | Meaning |
+| --- | --- |
+| `proxy_id` | Managed proxy ID used by the attempt; `null` for direct or unknown routes. |
+| `proxy_name` | Snapshotted proxy name, `direct/no_proxy`, or `unknown`. |
+
+Only proxy ID and name are stored. Proxy URL, protocol endpoint, host, port,
+username, password, and authorization data are excluded.
+
+The two sentinel names have strict meanings:
+
+- `direct/no_proxy`: the transport was explicitly given no proxy.
+- `unknown`: the route cannot be proven from event-time evidence. This includes
+  legacy events, pre-transport credential failures, and OpenAI WebSocket use of
+  the default HTTP client.
+
+Invariant: `proxy_id` is `null` if and only if `proxy_name` is one of the two
+sentinels. A managed proxy with a blank name (defensive only; `proxies.name` is
+non-empty) is labeled `proxy`. Both the struct normalizer used at append time
+and the JSON normalizer used on detail reads enforce this, so an event can never
+carry `proxy_id=null` together with a real proxy name.
+
+## Why the account snapshot is event-time evidence
+
+Account selection loads `ProxyID` and `Proxy` into one in-memory snapshot. HTTP,
+TLS-fingerprint, Bedrock, Gemini, Antigravity, OpenAI, and OpenAI WebSocket
+forwarding use that snapshot for managed proxy routing.
+Inference transports use a managed proxy only when both the binding ID and its
+hydrated proxy object are present; the attribution accessors use the same rule.
+OpenAI WebSocket additionally retains the existing default-client environment
+proxy behavior when that snapshot does not yield a usable proxy. The transport
+does not switch to a database backup proxy during a request.
+
+Expired proxy fallback happens before scheduling by atomically rewriting the
+account binding:
+
+- backup proxy: `proxy_id` becomes the backup ID and
+  `proxy_fallback_origin_id` stores the expired proxy ID;
+- direct fallback: `proxy_id` becomes null and
+  `proxy_fallback_origin_id` stores the expired proxy ID.
+
+Custom Anthropic relays receive the same snapshotted proxy as their encoded
+relay proxy parameter. OpenAI WebSocket requests keep the existing transport
+behavior: configured account proxies use the proxy client, while an empty
+account proxy leaves the HTTP client unset so `coder/websocket` uses
+`http.DefaultClient`, including its `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY`
+handling.
+
+For WebSocket errors without a usable account proxy, the event stores
+`proxy_id=null` and `proxy_name=unknown`. It does not infer whether the default
+client selected an environment proxy or a direct connection after the fact.
+This applies to every event produced while a request is on the WebSocket
+transport, including WS handshake/fallback errors and the first-output timeout
+raised by the WS passthrough relay; `opsUpstreamWSProxyAttribution` is the
+accessor for those sites and never returns `direct/no_proxy`.
+
+Credential acquisition failures that occur before the inference transport is
+opened are also recorded as unknown. The account's proxy binding is not treated
+as proof that the credential operation or an inference request used that route.
+
+Each failure site constructs a complete `OpsUpstreamErrorEvent`. Its literal
+sets `proxy_id` and `proxy_name` from the same route input used by the attempt.
+Credential-free accessors copy only the managed proxy ID and name. A fallback
+proxy needs no special event flag: its event-time ID and name are the historical
+route evidence. Shared helpers that assemble the event on behalf of a caller
+(`handleUpstreamTransportError`, `handleOpenAIUpstreamTransportError`,
+`appendOpenAICompactFallbackRetryOps`, `recordOpenAIRawStreamTruncation`,
+`newOpenAIFirstOutputTimeoutError`) stamp attribution themselves, so a caller
+cannot forget it. Every non-test `OpsUpstreamErrorEvent{` literal in
+`backend/internal/service` must either set `ProxyName` or be passed to one of
+those helpers; grep for literals missing `ProxyName` before merging changes
+that add a failure site.
+
+`appendOpsUpstreamError` accepts only the completed event. It does not receive
+an `Account`, query current account state, or infer proxy attribution while
+appending. Once appended, the event contains only scalar snapshot values, so
+later account mutation or failover cannot change an earlier event.
+
+Queue sanitization keeps attempt events newest-first under hard bounds:
+
+- the newest 16 attempts retain `detail` and `upstream_response_body` (each
+  capped at the queue body limit) plus `upstream_url`/`message` up to 2048
+  bytes;
+- older attempts keep timestamps, account, proxy, status, kind, stage, scope,
+  reason and a `upstream_url`/`message` trimmed to 512 bytes; an attempt whose
+  only payload was a cleared `detail` is still retained;
+- at most 256 attempts and roughly 512 KiB of serialized JSON are kept per
+  request. When either bound drops attempts, the oldest retained event carries
+  `dropped_earlier_attempts` with the number of discarded earlier attempts. The
+  newest attempt is always retained because it decides the request outcome.
+
+## Legacy events and analytics
+
+Legacy JSON is not rewritten in the database. Detail reads edit only the
+`proxy_id`/`proxy_name` keys of events that lack valid attribution, so keys
+written by older struct versions and the stored key order are preserved. The
+shared parser applies the same rule to the decoded structs. Both materialize
+missing attribution as:
+
+```json
+{
+  "proxy_id": null,
+  "proxy_name": "unknown"
+}
+```
+
+Proxy and region aggregation must use the event fields first. A safe grouping
+rule is:
+
+1. A non-null event `proxy_id` groups by that ID and uses the event
+   `proxy_name` as the historical label. A join to `proxies` may enrich current
+   metadata but must not replace the event label.
+2. `proxy_id=null` and `proxy_name=direct/no_proxy` groups as direct.
+3. Missing attribution, or `proxy_id=null` and `proxy_name=unknown`, groups as
+   unknown. Do not join through the account's current `proxy_id` and present it
+   as historical attribution.
+
+If an operator deliberately produces a current-account cohort for legacy data,
+the report must be labeled as a current snapshot; it is not historical proxy
+attribution.
