- Fix gofmt alignment in admin_service.go and trailing newline in
antigravity_credits_overages.go
- Suppress errcheck for fmt.Sscanf in client.go GetMinimumAmount
- apply default mapped model only when scheduling fallback is actually used
- preserve reasoning in OpenAI-compatible output via reasoning_content and avoid invalid input function_call ids
Backend:
- Detect and classify 403 responses into three types:
validation (account needs Google verification),
violation (terms of service / banned),
forbidden (generic 403)
- Extract verification/appeal URLs from 403 response body
(structured JSON parsing with regex fallback)
- Add needs_verify, is_banned, needs_reauth, error_code fields
to UsageInfo (omitempty for zero impact on other platforms)
- Handle 403 in request path: classify and permanently set account error
- Save validation_url in error_message for degraded path recovery
- Enrich usage with account error on both success and degraded paths
- Add singleflight dedup for usage requests with independent context
- Differentiate cache TTL: success/403 → 3min, errors → 1min
- Return degraded UsageInfo instead of HTTP 500 on quota fetch errors
Frontend:
- Display forbidden status badges with color coding (red for banned,
amber for needs verification, gray for generic)
- Show clickable verification/appeal URL links
- Display needs_reauth and degraded error states in usage cell
- Add Antigravity tier label badge next to platform type
Tests:
- Comprehensive unit tests for classifyForbiddenType (7 cases)
- Unit tests for extractValidationURL (8 cases including unicode escapes)
- Integration test for FetchQuota forbidden path
The SSE stream termination marker string was incorrectly included in
DefaultStopSequences, causing Gemini to prematurely stop generating
output whenever the model produced text containing that marker.
The SSE-level protocol filtering in stream_transformer.go already
handles this marker correctly; it should not be a stop sequence for
the model's text generation.
Add Anthropic Messages API support for OpenAI platform groups, enabling
clients using Claude-style /v1/messages format to access OpenAI accounts
through automatic protocol conversion.
- Add apicompat package with type definitions and bidirectional converters
(Anthropic ↔ Chat, Chat ↔ Responses, Anthropic ↔ Responses)
- Implement /v1/messages endpoint for OpenAI gateway with streaming support
- Add model mapping UI for OpenAI OAuth accounts (whitelist + mapping modes)
- Support prompt caching fields and codex OAuth transforms
- Fix tool call ID conversion for Responses API (fc_ prefix)
- Ensure function_call_output has non-empty output field

Add a doughnut chart showing usage statistics broken down by group on
the admin usage records page. The chart appears alongside the existing
model distribution chart (2-column grid), with the token usage trend
chart moved to a separate full-width row below.
Changes:
- backend/pkg/usagestats: add GroupStat type
- backend/service: add GetGroupStatsWithFilters interface method and implementation
- backend/repository: implement GetGroupStatsWithFilters with LEFT JOIN groups
- backend/handler: add GetGroupStats handler with full filter support
- backend/routes: register GET /admin/dashboard/groups route
- backend/tests: add GetGroupStatsWithFilters stubs to contract/sora tests
- frontend/types: add GroupStat interface
- frontend/api: add getGroupStats API function and types
- frontend/components: add GroupDistributionChart.vue doughnut chart
- frontend/views: update UsageView layout and load group stats in parallel
- frontend/i18n: add groupDistribution, group, noGroup keys (zh + en)
The ClientSecret constant was left as an empty string after
getClientSecret() was refactored to use defaultClientSecret.
Remove the dead constant and update the test accordingly.
- Fix oauth_test.go and client_test.go to use defaultClientSecret
variable instead of env var (init() already sets the default)
- Align migration 058 gemini-3-pro-high/low/preview mappings with
constants.go (map to 3.1 versions)
Add a built-in default for ANTIGRAVITY_OAUTH_CLIENT_SECRET so the
service works out of the box without requiring environment variable
configuration. The env var can still override the default.
