* 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).

* feat(token): support custom auto group order
* feat(keys): enhance auto group presentation
* fix(keys): rework Auto flow border and compact inherited order
The Auto group highlight previously tinted the whole control surface
with a gradient and animated only a 1px top sweep, which read as a
background color rather than a flowing border. Replace it with a
border-only effect: an aria-hidden, pointer-events-none overlay whose
conic gradient is masked down to a thin ring hugging the rounded
perimeter, so the highlight travels around all four edges and corners
every 3.2s. The interior stays neutral with a restrained static
primary border and glow; prefers-reduced-motion hides the moving
layer while keeping the static emphasis.
The inherited global Auto order also rendered as spacious two-line
rows with circular sequence markers, wasting drawer space. Render it
as a compact wrapping strip of one-line chips (index, name, ratio
badge) with descriptions kept accessible via title and sr-only text,
scrolling only past a much smaller max height.
Custom add/remove/reorder editing, empty-array inheritance semantics,
and the submit payload are unchanged.
* fix(keys): preserve Auto inheritance and unify effects
* refactor(keys): temporarily disable AutoGroupBadge in api-key-group-cell
Follow-up to #6518 (issue #6480) addressing three review findings:
- Document and lock in arrears semantics for the wallet Reserve top-up:
when an auto-group retry lands on a more expensive group, the full
reservation delta is deducted unconditionally (balance may go
negative), mirroring settlement, so the logged pre-consumed quota
always reconciles with the actual balance movement. Genuine DB
errors still fail the attempt with update_data_error. Subscription
funding keeps its insufficient-quota behavior: subscriptions enforce
a hard used<=total cap and do not support arrears.
- PriceData.FreeModel is cleared when a retry switches from a free
group to a paid one, keeping it consistent with the billing session
created at that point.
- getChannel refreshes GroupRatioInfo only after channel selection
succeeds, and the retry loop records the channel in use_channel
before PrepareTieredBillingForSelectedGroup can fail.
* fix(oauth): stop treating a foreign window.opener as a bind flow
The /oauth/:provider callback decided between an account bind and a plain
login with `window.opener ? 'bind' : 'login'`. Any tab opened from an
external link (target="_blank", Slack, mail clients, another site) carries
a live opener, and that opener survives the cross-origin round trip to the
identity provider. Such a login callback was therefore misread as a bind:
it posted a handshake to a window that speaks no such protocol, showed the
"binding your account" screen, and hung until the 30s deadline fired with
"OAuth binding timed out" — while the backend was never called at all.
Reproduced against a real Keycloak round trip: a tab opened via window.open
still reports window.opener !== null on the callback, so mode resolved to
'bind' for an ordinary OIDC login.
A bind now requires positive proof: the popup we open for it is same-origin
(about:blank) before being sent to the provider, so we stamp its own
sessionStorage. The stamp rides through the provider round trip and is
scoped to that popup alone, so a login tab can never carry it. Ambiguity
resolves to 'login', which is the recoverable direction.
Affects every provider sharing this callback (OIDC, GitHub, Discord,
LinuxDO, custom).
* fix(oauth): harden bind popup detection
* docs: add design spec for OIDC custom display name
Mirrors the existing Custom OAuth Provider name pattern so admins can
