* fix(relay): set Request.GetBody so the HTTP/2 transport can transparently retry after an upstream stream reset
The outbound request body is a type-erased io.Reader over BodyStorage, so
net/http cannot derive Request.GetBody (it only does so for *bytes.Reader,
*bytes.Buffer and *strings.Reader). With GetBody nil, the HTTP/2 transport
cannot transparently retry a request once the body has been written and the
upstream resets the stream with a retryable error (REFUSED_STREAM, or a
connection-level GOAWAY); the relay request then fails with:
http2: Transport: cannot retry err [...] after Request.Body was written;
define Request.GetBody to avoid this error
This affects every relay path that goes through DoApiRequest (chat, claude,
gemini, responses, embedding, image, rerank).
BodyStorage (memory and disk) already implements io.Seeker, so replay support
only needed wiring:
- NewOutboundJSONBody additionally returns a getBody that rewinds the storage
and hands out a fresh non-closing reader. The transport only calls GetBody
after the previous attempt's body has been abandoned, so the rewind cannot
race an in-flight read.
- RelayInfo carries it in the new UpstreamRequestGetBody field, set alongside
UpstreamRequestBodySize by the handlers that build storage-backed bodies.
- applyUpstreamGetBody (symmetric with applyUpstreamContentLength) wires it
into DoApiRequest/DoFormRequest/DoTaskApiRequest, only when req.GetBody is
still nil.
Also remove the hand-rolled GetBody override in DoTaskApiRequest: it returned
the same already-consumed reader, so any transport-level replay would have
silently sent an empty body, and it clobbered the correct snapshot-based
GetBody that net/http derives from the *bytes.Reader bodies the task adaptors
pass in. For non-replayable bodies GetBody now stays nil, so a retry fails
loudly instead of corrupting the request.
Covered by unit tests plus an end-to-end raw-frame HTTP/2 test that resets
the first stream with REFUSED_STREAM after the body is written and asserts
the transport transparently retries with the complete body.

* fix(relay): hand out independent readers from GetBody (address review)
Per the http.Request.GetBody contract ("returns a new copy of Body"),
each call must yield a reader with its own cursor. The previous
implementation rewound and reused the shared BodyStorage, so two
consecutive GetBody readers would interfere with each other, and a
replay could disturb the primary body's offset under extreme transport
timing (e.g. attempt N's body write not yet fully abandoned when the
transport builds attempt N+1).
Instead of snapshotting the payload (an extra copy), add
BodyStorage.NewReader, which returns an independent zero-copy reader:
- memory mode: a fresh bytes.Reader over the same immutable backing
array;
- disk mode: a separate file descriptor over the cache file, so the
transport closing a replayed body only closes that descriptor.
NewOutboundJSONBody's getBody now simply hands out storage.NewReader,
and once the handler releases the storage, GetBody fails with
ErrStorageClosed instead of replaying stale data.
Tests: interleaved reads across two replay readers and the primary
body each observe exactly their own byte stream, for both the memory
and the disk-backed storage; the existing GetBody and HTTP/2 retry
suites still pass (h2 e2e tests flake-free with -count=20).

* test(relayconvert): add golden snapshot matrix and relaykit boundary guard
Phase 0 of the relaykit extraction plan: pin byte-level output of every
registered (from,to) request/response/stream conversion route, and
forbid kit-bound packages from growing host-only imports.
* wip(relayconvert): drop gin.Context from converter signatures; add convmeta draft
Phase 1 in progress: relayconvert now takes context.Context; host media
resolver adapts gin.Context back at the service boundary.
* refactor(relayconvert): decouple converters from RelayInfo, gin, and settings
Phase 1 of the relaykit extraction plan:
- converters now depend on convmeta.Meta (implemented by RelayInfo) instead
of *relaycommon.RelayInfo; ClaudeConvertInfo and the format guesser move
to convmeta with aliases left behind
- host settings reach converters via a convmeta.Options snapshot built in
RelayInfo.ConvOptions; no more model_setting/reasoning global reads inside
the conversion layer
- effort-suffix helpers move to service/relayconvert/reasoning (old package
forwards); chat-to-responses upgrade policy moves to service (host routing
logic, not conversion)
- golden conversion matrix unchanged
* test(relayconvert): tighten boundary — kit packages now free of gin/setting imports
* refactor(dto): drop gin and logger dependencies
Phase 2 (part 1): dto.Request.IsStream now takes *http.Request instead of
*gin.Context (Gemini's impl reads query/path off the std request); dto's
three logger calls become common.SysError. Boundary test allowlist is now
empty — kit-bound packages import no gin/setting/logger/model.
* refactor(kit): extract dependency-free kitutil; dto/types/relayconvert stop importing common
Phase 2 of the relaykit extraction plan:
- new service/relayconvert/kitutil holds the pure helpers the kit needs
(JSON wrappers, pointer/string/uuid/timestamp utils, MaskSensitiveInfo,
pluggable LogInfo/LogError hooks, Debug flag)
- dto, types, and all relayconvert packages now use kitutil; their only
remaining internal deps are dto/types/constant
- common keeps every original symbol (MaskSensitiveInfo delegates to
kitutil) so host code is untouched; main.go routes kit logging into
common.SysLog/SysError and mirrors DebugEnabled
- golden conversion matrix unchanged
* refactor(kit): move EndpointType/FinishReason to types; OpenRouter dialect via Options
Kit packages (dto/types/relayconvert/reasonmap) no longer import constant:
- EndpointType and finish-reason values live in types; constant re-exports
- the OpenRouter special-case in claude->openai request conversion reads
Options.OpenRouterDialect, set by the host from the channel type;
InitChannelMeta invalidates the cached snapshot on channel switch
* refactor: extract relaykit submodule (dto/types/relayconvert/reasonmap)
Phase 3 of the relaykit extraction plan:
- new go module github.com/QuantumNous/new-api/relaykit containing dto
(minus task family), types, relayconvert (with convmeta/kitutil/reasoning),
and reasonmap; host consumes it via require + replace, go.work for dev
- task-family dto (task/suno/midjourney/video) stays in the host dto
package; dual-consumer host files alias it as taskdto
- relaykit builds and tests standalone (GOWORK=off): no host imports,
no gin, no DB, no settings
- golden conversion matrix unchanged
* build(docker): copy relaykit/go.mod before go mod download
The local-replace submodule's go.mod must exist inside the build context
for the main module graph to resolve.
* fix: address relaykit extraction regressions
* fix: address relaykit review regressions
* docs: document Meta nil receiver contract
* fix(relaykit): fail OpenAI→Claude conversion without max_tokens; reject negative default_max_tokens
The Claude Messages API requires max_tokens (omitting it is a 400
"Field required"), but with a nil Options.Claude.DefaultMaxTokens hook
the converters silently emitted a request the upstream is guaranteed to
reject. Both OpenAI Chat and Responses → Claude conversions now return
sharedclaude.ErrMissingMaxTokens when no path (client value, default
hook, thinking-adapter floor) supplied one. Unreachable in the host,
which always configures the hook.
Host side, claude.default_max_tokens now rejects negative values at the
option API before persisting — they would wrap into huge unsigned values
during conversion. Zero stays allowed: the current API treats
max_tokens: 0 as cache pre-warming.

* fix: harden billing usage settlement and hot-path route matching
- estimate Gemini completion tokens locally when billable usageMetadata is
prompt-only but output content was received (e.g. client aborts the stream
before the final chunk), and rebuild the attached billing_usage as estimated
so settlement does not bill zero output tokens
- guard NewClaudeMessagesBillingUsage against all-zero ClaudeUsage, matching
the OpenAI/Gemini constructors, so a zero billing_usage cannot override a
non-zero top-level usage during settlement
- cache compiled advanced-custom route model regexes; they run on the request
hot path and were recompiled per request
- move the effectiveBillingUsage remap to PostTextConsumeQuota only, and
document that calculateTextQuotaSummary expects remapped usage
- document the updatePricingLock -> channelSyncLock lock ordering that
InitChannelCache/CacheUpdateChannel rely on, and the aux-struct pitfall in
GeminiChatResponse.UnmarshalJSON
* fix(openai): harden Chat-to-Responses compatibility

Add deterministic service tests and relay SSE tests for the conversion path.

Three layered optimizations targeting Gemini-style 5MB base64 payloads where
RSS could balloon to tens of GB under concurrent load:
1. Byte-based param override (relay/common/override.go)
- Switch legacy/operations hot paths from common.Marshal round-trips and
map[string]any conversions to gjson/sjson on []byte directly.
- Avoids cloning 5MB strings during each Set/Delete operation.
2. strings.Builder for Gemini response markdown (relay/channel/gemini/relay-gemini.go)
- Replace string concatenation + strings.Join when assembling
"" content for inline image responses.
- Pre-allocates capacity from inline_data byte sizes.
3. Outbound BodyStorage + streaming Decoder (this commit's core)
- New relay/common/outbound_body.go helper wraps marshaled upstream bodies
in common.BodyStorage, allowing disk-cache mode to offload jsonData to
a temp file while waiting for upstream TTFB. The original []byte can
then be GC'd, removing ~5MB/req of heap residency during the longest
window of a request.
- All 7 relay handlers (gemini/claude/responses/embedding/image/compatible/
rerank) plus chat_completions_via_responses adopt the helper with
defer closer.Close() and explicit jsonData = nil.
- relay/common/relay_info.go: new UpstreamRequestBodySize so
relay/channel/api_request.go can populate req.ContentLength (lost when
body becomes a type-erased io.Reader).
- common/gin.go UnmarshalBodyReusable: when storage is disk-backed and
content-type is JSON, decode via DecodeJson(storage) instead of
storage.Bytes()+Unmarshal, removing one transient 5MB copy per request.
memory mode and form/multipart paths unchanged.
- Added support for tiered billing expressions in the billing system.
- Introduced new types and functions for handling billing expressions, including caching and execution.
- Updated existing billing logic to accommodate tiered billing scenarios.
- Enhanced request handling to support incoming billing expression requests.
- Added tests for tiered billing functionality to ensure correctness.
