1. Redeem code affiliate rebate: balance-type redeem codes now trigger
invite rebate for the inviter. Payment fulfillment uses context key
to prevent double-rebate.
2. Batch concurrency update: new POST /admin/users/batch-concurrency
endpoint supporting mode=set/add with all=true for all users.
3. Markdown page rendering: new GET /api/v1/pages/:slug API serves local
.md files. Custom menu items with url="md:slug" render markdown with
collapsible TOC sidebar, scroll spy, and copy buttons on code blocks.

When a preflight ping fails or previous_response_not_found is returned,
sub2api drops previous_response_id and retries. But if the payload
contains function_call_output (tool results), the upstream API loses
the response chain context needed to match tool_result to tool_use,
causing 400: "No tool call found for function call output".
Add hasFunctionCallOutput checks to both recovery paths:
- Preflight ping failure recovery (forcePreferredConn path)
- recoverIngressPrevResponseNotFound function
DeriveUpstreamEndpoint hard-codes /v1/responses for PlatformOpenAI,
but APIKey accounts probed to not support Responses API are forwarded
directly to /v1/chat/completions via forwardAsRawChatCompletions.
Add resolveRawCCUpstreamEndpoint which returns /v1/chat/completions
when the account's extra.openai_responses_supported is explicitly false.
The forwardAsRawChatCompletions path (used when APIKey accounts target
upstreams that don't support Responses API, e.g. DeepSeek) was missing
reasoning_effort and service_tier extraction, causing all reasoning
effort values to be silently dropped.
Extract both from the raw Chat Completions body before forwarding, and
propagate them through streamRawChatCompletions / bufferRawChatCompletions
to the OpenAIForwardResult.
Fix four issues flagged by copilot-pull-request-reviewer on PR #2143:
1. Probe URL missing /v1 prefix (openai_apikey_responses_probe.go)
Replaced bare TrimSuffix + "/responses" with buildOpenAIResponsesURL(),
which handles bare domain → /v1/responses correctly. Affected:
- ProbeOpenAIAPIKeyResponsesSupport (probe URL)
- TestAccount endpoint (apiURL for APIKey accounts)
2. Create endpoint not triggering probe (account_handler.go)
Capture created account from idempotent closure and call
scheduleOpenAIResponsesProbe after success, same pattern as
BatchCreate and Update.
3. Tests (openai_gateway_chat_completions_raw_test.go)
Added TestBuildOpenAIChatCompletionsURL (7 cases covering
bare domain, /v1 suffix, trailing slash, third-party domains,
whitespace) and TestBuildOpenAIResponsesURL_ProbeURL (6 cases
locking the probe URL construction for bare-domain inputs).
All unit tests pass; go build ./cmd/server/ clean.
