+#### OpenAI Responses WebSocket ingress limits
+
+`gateway.openai_ws` bounds the lifetime and aggregate count of client-facing
+Responses WebSocket sessions. These safeguards apply independently from
+per-turn user and account concurrency slots, which are released between turns.
+
+```yaml
+gateway:
+  openai_ws:
+    # Total time to receive and decompress the first client message.
+    client_first_message_timeout_seconds: 30
+    # Close a client socket idle between completed turns; 0 disables this safeguard.
+    ingress_inter_turn_idle_timeout_seconds: 300
+    # Distributed API-key limit for live client ingress sessions; 0 disables it.
+    max_ingress_connections_per_api_key: 64
+```
+
+The first-message timeout is a total read deadline. Deployments that accept
+large contexts or image-heavy requests over slower links can raise it to
+120-300 seconds. It expires before HTTP bridge routing, so bridge mode does not
+override this limit.
+
+The connection cap is coordinated through Redis using a 60-second lease that
+is refreshed every 20 seconds. A process that cannot confirm a lease for a
+full lease lifetime closes its local WebSocket rather than continuing outside
+the global cap.
+
+Enable the v2 mode router before selecting an account-level WS mode such as
+`http_bridge`:
+
+```yaml
+gateway:
+  openai_ws:
+    mode_router_v2_enabled: true
+```
+
+Or set `GATEWAY_OPENAI_WS_MODE_ROUTER_V2_ENABLED=true` in the environment.
+Use `http_bridge` for client-WebSocket/upstream-HTTP operation when rolling out
+or mitigating upstream WebSocket issues.
+
 #### ⚠️ Important: Creating the Admin Account
 
 The initial admin account is **only created via the setup wizard** (served at `http://<host>:8080` on first run). The `default.admin_email` / `default.admin_password` fields in `config.yaml` are **not used** to create it — they exist in the template for historical reasons.

+New Grok image and video generation requests use a media-specific eligibility check. API-key accounts remain eligible. OAuth accounts require positive paid-entitlement evidence from the xAI billing probe; Free, forbidden, missing, malformed, and inconclusive billing observations are excluded from new media generation. Unobserved OAuth accounts are probed before the first media request is forwarded, and 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.

+# Ingress rejection log cleanup
+
+This maintenance command removes historical admission rejections from
+`ops_error_logs` without matching unrelated authentication or upstream errors.
+It is a dry run unless `--execute` is supplied, and always requires an explicit
+RFC3339 cutoff.
+
+```sh
+go run ./cmd/cleanup-ingress-reject-logs --before 2026-07-17T00:00:00Z
+go run ./cmd/cleanup-ingress-reject-logs --before 2026-07-17T00:00:00Z --execute
+```
+
+Run the execute form only after every application instance has been upgraded so
+older instances cannot add new ingress rejection rows below the chosen cutoff.
+The classifier intentionally retains invariant failures such as
+`USER_NOT_FOUND`, database errors, quota/billing errors, and upstream failures.
+
+After the rollout and cleanup are verified, run
+`backend/scripts/finalize-ingress-reject-cleanup.sql` in a maintenance window to
+remove the deprecated plaintext-key audit table and attribution columns.
