The Antigravity native Gemini route (generateContent) expects each
contents entry to carry an explicit "user" role, matching the request
shape used by the established Antigravity account-test flow. Without it
the probe body is rejected with 400 INVALID_ARGUMENT, so Gemini channel
monitors report false failures.
Add the explicit role to the Gemini provider adapter body and cover it
with a regression test that parses the generated request body.
Cyber-policy detection only inspected response.failed, and the ingress check ran after error-specific early returns. As a result, error-shaped failures and the connection-pool, HTTP-bridge, and WSv2 paths could miss cyber-policy hits.
Centralize event marking and invoke it before retry and failover returns across the WebSocket implementations. Preserve the recorded guard during account failover and defer connection blocking until the logical failover chain completes, avoiding duplicate records while ensuring subsequent turns are blocked.
Official OpenAI hosts and models.dev entries without an api field left
Astra falling back to reasoning effort none and empty Fast tiers. Persist
complete per-model metadata, advertise Astra reasoning/Fast locally, and
surface partial sync warnings when image models remain incomplete.

Anthropic gates newer models on a minimum Claude Code client version. With
CLICurrentVersion pinned at 2.1.220, claude-fable-5-1 fails every request with
"Claude Code 2.1.220 does not support this model; version 2.1.251 or newer is
required", and the only fix is a release that bumps one constant.
Add SUB2API_CLAUDE_CLI_VERSION, mirroring what internal/pkg/xai already does
with XAI_GROK_CLI_VERSION. CLICurrentVersion remains the built-in pin; the new
CLIVersion() is what every consumer reads. With no env var set the resolved
value equals the pin, so existing deployments are unaffected.
The value is resolved once at package init rather than per call: the User-Agent
header and the request body's cc_version are written by different code paths for
the same request, and reading different values would make that request
contradict itself.
Validation is strict (three numeric segments, not below the pin) because
identity_service.go documents what a malformed version does once it reaches an
account's persistent fingerprint: sustained 429s without reset headers, 5s
fallback cooldown, pool collapse into a 503 storm, and no reset entry point.
Invalid values warn and fall back rather than being silently dropped.
