Keepalive is gated on downstream idle, not upstream tick cadence. The old
fixture wrote progress events every 250ms and could finish without a true
1s idle window on loaded CI runners, so ":\n\n" never appeared. Pause after
preamble long enough for the keepalive ticker before completing the stream.
Fix golangci unused/gofmt on the gentle-backfill path. Plot matrix and
line-chart X axes on the selected [requested_start, requested_end)
window (empty slots while backfill lags), and let plain mouse-wheel zoom
narrow the visible interval so pulse blocks grow wider.
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.
A Responses stream that ends with response.completed but carries no output,
no usage and no error (only response.created + response.completed observed)
is a silent upstream refusal. It was previously treated as a successful
turn, recording 0 input / 0 output tokens without triggering failover, so
clients saw an empty reply and usage was never billed.
Detect the empty terminal event in both the standard and passthrough
streaming paths while nothing has been written to the client, and return an
UpstreamFailoverError so the next account is tried; when failover is
exhausted the client gets an explicit Responses-format error instead of an
empty success. Streams with any semantic output, usage or error are
untouched. Fixes#5009.
OpenAI upstream requires reasoning input item ids to begin with 'rs' and
rejects replayed item_* ids with 400 ("Expected an ID that begins with
'rs'."). shouldStripOpenAIResponsesInputItemID handled message (msg) and
tool call (fc) ids but not reasoning items, so long Codex sessions restored
through the OpenAI API key passthrough path failed with a converted 502.
Strip non-rs reasoning ids while preserving valid rs_* ids, mirroring the
existing message/tool-call handling. Fixes#5410.
Default channel_monitor_mode to v1 (opt-in V2) so upgrades keep active
probes; existing explicit v2 rows are left alone via ON CONFLICT DO NOTHING
plus migration checksum compatibility for already-applied 195.
V2 first-enable backfill no longer compresses ticks to 5s or uses 24h
chunks. Each tick does recent overlap plus at most one historical chunk
with depth-based ceilings (2h/4h/6h), adaptive grow/shrink, and failure
backoff. Error request_id dedup is bounded by a 90-minute lookback so
ops_error_logs is not scanned for full history.
Also align hide_throughput parse default with privacy-preserving public
runtime (missing key → true).
Check Close/CloseNow errors, drop unused helpers and dead constants,
lowercase ST1005 error strings, and stop discarding unwrap status as an
unused assignment so CI golangci-lint passes.
Expand Use Key Grok CLI config.toml to include production-oriented sections
from working gateway setups: full [endpoints], preferred_method=api_key,
image_description, auto_compact threshold, and Imagine image/video feature
overrides with guided comments.
Ship Use Key templates that match Grok Build / Codex best practice: env
vars + multi-model config.toml with api_backend=responses, env_key over
hardcoded secrets, and clearer shell/path guidance for Claude/Codex/OpenCode.
Also set free_quota_token_limit default to 500k (24h soft-gate), clean up
personal-dev-only comments, and keep billing test fixtures aligned.
Mint durable grok_audio/grok_realtime usage ids, avoid CLI headers on api.x.ai
voice, retry video pending store and fail-closed when snapshot is missing without
status duration, align pure-video ImageCount tests, and escalate unset search
price_per_1k to error-level logs.
Remove optional upload_url / fake connectivity-only success from admin video
tests. Stamp Grok CLI headers only on the CLI proxy so OAuth media against
api.x.ai can complete and preview video like the gateway path.
Show free accounts only the rolling 24h soft-gate bar; paid accounts show
7d/30d and prepaid money. Drop the always-visible manual probe chip from the
usage cell in favor of scheduled recovery and usage load.
Classify free-usage bodies during account tests without quarantining content
policy, and mark billing/spending-limit refresh failures as transient so
accounts stay probe-eligible.
Store CreatedAt on pending billing at video create and use wall-clock E2E
latency when status/content first observes official done+video.url, so usage
logs no longer record only the single poll hop.
Align gateway Grok media/voice paths and model lists, harden upstream failure
and quota handling, clear non-Grok video generation config migration, and polish
temp-unsched/status indicators with model whitelist updates.
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).
Add mode-first connectivity probes for text/image/video/search/tts/stt/realtime,
standalone voice and web-search paths, media upload options, and in-browser
image/audio/video preview (including ZDR-safe b64 images and edit validation).
