Skip OpenAI messages-dispatch gpt-5.x defaults for OpenCode groups and
composite OpenCode targets. Filter unpriced claude-* billing candidates,
estimate count_tokens locally, sanitize body session IDs before setting
X-OpenCode-Session, and treat Zen 402 as recoverable payg cooldown.
Stop rewriting the inbound body before protocol routing so account
model_mapping applies once and usage_logs.model stays the client name.
Keep the internal platform ID opencode_go. Product surface is OpenCode
with account_mode zen|go, model-aware routing across Chat Completions,
Responses, and Anthropic Messages, and X-OpenCode-Session derived from
prompt_cache_key / metadata.user_id so prompt cache can hit.
Unmatched models fall back to /v1/chat/completions. Related to #6742.
Cyber-policy detection only inspected response.failed, and the ingress check ran after error-specific early returns. As a result, error-shaped failures and the connection-pool, HTTP-bridge, and WSv2 paths could miss cyber-policy hits.
Centralize event marking and invoke it before retry and failover returns across the WebSocket implementations. Preserve the recorded guard during account failover and defer connection blocking until the logical failover chain completes, avoiding duplicate records while ensuring subsequent turns are blocked.
OpenAI/Composite groups can now reject requests that exceed the max
reasoning effort instead of always rewriting them down to the ceiling.
Existing groups keep the previous auto-downgrade behavior.
- Accept fast|priority (canonical priority), flex|auto|default|scale on
/v1/responses and /v1/chat/completions; reject unknown/empty/non-string
with HTTP 400; omitted and null stay compatible.
- Propagate service_tier through JSON/SSE, Responses<->Chat conversions,
fallback paths and HTTP->upstream WebSocket bridge.
- Billing prefers the upstream terminal tier; the outbound (policy-
transformed) tier is used only when upstream omits the field.
Explicit upstream default bills Standard even when Fast was requested.
- Pricing: Fast premium 2x Standard for gpt-5.6-sol/terra/luna and
gpt-5.4; 2.5x for gpt-5.5; channel FastMultiplier stays authoritative.
- Live verification (official Codex 0.149.0 + gateway, HTTP & WS):
upstream ChatGPT backend may return terminal default even when the
account catalog advertises priority; billing follows the actual tier.
sanitizeGroupMessagesDispatchFields forces AllowMessagesDispatch=false for
every non-openai platform including composite, and the gate checked only the
group platform — so composite requests resolved to grok/CN targets were
rejected 403 on /v1/messages and /v1/messages/count_tokens before reaching
the composite target whitelist, leaving the CN rollout unusable for
Claude-protocol clients.
- allowOpenAICompatibleMessagesDispatch: composite groups resolved to a
grok/CN target get the same exemption as the standalone platforms;
openai-resolved and unresolved targets keep requiring the switch
- resolveOpenAIMessagesDispatchMappedModel: skip the group-level dispatch
model mapping (openai-specific gpt defaults) for composite grok/CN
targets — model rewriting stays with account-level model_mapping
- Responses WebSocket composite whitelist stays openai+grok: CN accounts
cannot pass the WSv2 ingress transport filter and the WS HTTP bridge
has no Responses conversion for them, so admitting CN targets only
turns a clear policy rejection into a misleading no-available-account
- widen the responses/input_tokens and messages/count_tokens composite
gates to the shared openai-compatible text whitelist so CN targets get
the same local-estimate token counting as generation
- restore the Claude default-model fallback for standalone CN groups
(admin candidates and custom models list) while keeping composite
listings limited to CN account mapping keys
- refresh the scheduler bulk-rebuild comment and bucket capacity hints
for the 8-platform canonical set
