Address gaps found in adversarial verification of the in-flight balance
reservation:
- Early release: the reservation is now a ref-counted handle carried on the
request context. Billing tasks submitted via submit*UsageRecordTask take a
ref and return it only after RecordUsage has run; with reservation enabled
the balance cache is deducted synchronously inside the billing task, so the
reservation is released only after admission can see the deduction. Dropped
tasks return their ref immediately. The reservation is renewed every ttl/3
while the handler runs; after the handler returns it is no longer renewed,
so the post-handler hold is bounded by one TTL.
- Estimate: use the same billing model (channel mapping + BillingModelSource,
max over requested/mapped when ambiguous) and ModelPricingResolver (group
ModelPricing incl. wildcards, channel per_request/image/video/token
overrides), default/group/user rate + peak multiplier, plus image, video,
audio and search surcharge kinds. Unpriced requests fail open with a
throttled log; new billing.inflight_reservation.fail_closed_on_unpriced
(default false) rejects them instead.
- Wire images, embeddings, web/x search, alpha search, grok media generation,
grok realtime/voice, OpenAI-platform /v1/messages and ResponsesWebSocket
(session-level reservation with renewal).

Balance-mode admission only checked cached balance > threshold, so N
concurrent expensive requests could all pass and overdraw the user.
Add a Redis in-flight reservation: at admission estimate a conservative
per-request cost (input estimate + output price x max_tokens, times rate
multiplier) and atomically require cached_balance - inflight >= estimate
(first in-flight request always admitted). Reservations are released via
defer on every path and expire by TTL. Fails open on estimation / Redis
errors. Configurable via billing.inflight_reservation (enabled by default).

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.
Add gateway.models_list_read_max_bytes with the existing 8 MiB behavior as its default, and apply it consistently to generic, Codex, and Antigravity model-list reads.
Read one sentinel byte for Codex manifests so oversized responses return an explicit bounded upstream error instead of malformed JSON.
H1/H2: bill search and voice with code defaults when group prices are
nil (explicit 0 remains free); bump API key auth snapshot to v19 and
refresh incomplete media/search/audio projections.
M1–M6: free-quota soft gate fails open on cache miss with background
refresh and 60s default TTL; correct password_auth config docs; default
cross-client model map to true (→ grok-4.5); audit /tts and /web_search;
exclude composite from migration 220 video-price clears; never let a
search surcharge mask token pricing failures.
Require oauth state/redirect consistency, fail closed on missing proxy,
and remove password login from create/reauth UI (admin-only password path stays off by default).
The proxy stream circuit introduced in v0.1.164 (#4749) removes every
account behind a quarantined proxy from scheduling. When all schedulable
accounts share one proxy (a common deployment), two mid-stream
disconnects within a minute zeroed out capacity for 10 minutes and every
request failed with 502. One HTTP/2 connection loss also killed all
multiplexed streams at once, tripping the threshold from a single event.
- Quarantine now degrades to a preference: when the only reason no
account is available is proxy quarantine, selection retries once with
the quarantine bypassed, so capacity can never reach zero.
- Disconnects within 3s per proxy collapse into one failure event.
- Add gateway.openai_proxy_stream_circuit.disabled escape hatch.
- A completed stream still clears the quarantine immediately; TTL,
thresholds and recording guards are unchanged.
- parseSettings now reports passkey_enabled=false whenever the WebAuthn
deployment config is absent: a stale "true" row left behind after the
config is removed previously made the admin update gate reject every
settings save while the UI toggle was disabled, leaving no recovery
path from the admin panel. Added a regression test.
- update the admin settings API contract goldens with the new
passkey_enabled/passkey_configured/passkey_rp_id/passkey_rp_origins
fields.
- errcheck: check rows.Close in passkey repository (repo convention).
- staticcheck QF1001: apply De Morgan's law in WebAuthn origin scheme
validation.
