Move 529 overload cooldown configuration from config file to admin
settings UI. Adds an enable/disable toggle and configurable cooldown
duration (1-120 min) under /admin/settings gateway tab, stored as
JSON in the settings table.
When disabled, 529 errors are logged but accounts are no longer
paused from scheduling. Falls back to config file value when DB
is unreachable or settingService is nil.
Update model mapping target for claude-haiku-4-5 and
claude-haiku-4-5-20251001 from claude-sonnet-4-5 to claude-sonnet-4-6.
Includes migration script, default constants, and test updates.
Empty text blocks ({"type":"text","text":""}) cause Anthropic upstream to
return 400: "text content blocks must be non-empty". This was not caught
by the existing error detection pattern in isThinkingBlockSignatureError,
nor handled by FilterThinkingBlocksForRetry.
- Add empty text block stripping to FilterThinkingBlocksForRetry
- Fix isThinkingBlockSignatureError to match new Anthropic error format
- Add fast-path byte patterns to avoid unnecessary JSON parsing

Add a platform filter dropdown to the admin subscriptions view, allowing
filtering subscriptions by platform (Anthropic, OpenAI, Gemini, etc.)
through the group association.

Cover IsValidModelSource/NormalizeModelSource, resolveModelDimensionExpression SQL expressions, invalid model_source 400 responses on both GetModelStats and GetUserBreakdown, upstream_model in scan/insert SQL mock expectations, and updated passthrough/billing test signatures.
Support querying model statistics by 'requested', 'upstream', or 'mapping' dimension. Add resolveModelDimensionExpression for safe SQL expression generation, IsValidModelSource whitelist validator, and NormalizeModelSource fallback. Repository persists and scans upstream_model in all insert/select paths.
Propagate UpstreamModel through ForwardResult and OpenAIForwardResult in Anthropic direct, API-key passthrough, Bedrock, and OpenAI gateway flows. Extract optionalNonEqualStringPtr and optionalTrimmedStringPtr into usage_log_helpers.go. Store upstream_model only when it differs from the requested model.
Also introduces anthropicPassthroughForwardInput struct to reduce parameter count.
- Add compile-time interface assertion for sessionWindowMockRepo
- Fix flaky fallback test by capturing time.Now() before calling UpdateSessionWindow
- Replace stale hardcoded timestamps with dynamic future values
- Add millisecond detection and bounds validation for reset header timestamp
- Use pause/resume pattern for interval in UsageProgressBar to avoid idle timers on large lists
- Fix gofmt comment alignment

TestConnection now reuses antigravityRetryLoop instead of a standalone
HTTP loop, gaining credits overages, smart retry, and 429/503 backoff
for free. AccountSwitchError is caught and surfaced as a friendly
message. Also populates RateLimitedModel in TempUnscheduled switch error.
Test fixes:
- Use RATE_LIMIT_EXCEEDED in 503 short-delay test to avoid 60x1s timeout
- Clamp waitDuration=0 instead of 999s to avoid 15s max-wait timeout
- Enhance mockSmartRetryUpstream with repeatLast and body caching
Click on a group name, model name, or endpoint name in the distribution
tables to expand and show per-user usage breakdown (requests, tokens,
actual cost, standard cost).
Backend: new GET /admin/dashboard/user-breakdown API with group_id,
model, endpoint, endpoint_type filters.
Frontend: clickable rows with expand/collapse sub-table in all three
distribution charts.
The 5h window reset time displayed for Setup Token accounts was inaccurate
because UpdateSessionWindow predicted the window end as "current hour + 5h"
instead of reading the actual `anthropic-ratelimit-unified-5h-reset` response
header. This caused the countdown to differ from the official Claude page.
Backend: parse the reset header (Unix timestamp) and use it as the real
window end, falling back to the hour-truncated prediction only when the
header is absent. Also correct stale predictions when a subsequent request
provides the real reset time.
Frontend: add a reactive 60s timer so the reset countdown in
UsageProgressBar ticks down in real-time instead of freezing at the
initial value.

OAuth upstreams (ChatGPT) reject requests containing role:"system" in
the input array with HTTP 400 "System messages are not allowed". Extract
such items before forwarding and merge their content into the top-level
instructions field, prepending to any existing value.

Antigravity streaming handlers were missing the keepalive mechanism
that exists in the standard gateway, causing proxy/CDN idle timeouts
to break connections during long thinking phases (e.g. claude-opus-4-6).
This resulted in truncated responses with missing tool calls.
Add StreamKeepaliveInterval support to all three Antigravity streaming
paths: Claude SSE, Gemini SSE, and upstream passthrough.
Removes hasMeaningfulWindowStats guard so the /usage endpoint consistently
returns WindowStats for both time windows. The frontend now controls
zero-value display filtering at the component level.
- Fix gofmt alignment in admin_service.go and trailing newline in
antigravity_credits_overages.go
- Suppress errcheck for fmt.Sscanf in client.go GetMinimumAmount
Remove SimulateClaudeMaxEnabled field and related logic from
admin_service.go, and remove applyClaudeMaxCacheBillingPolicyToUsage,
applyClaudeMaxNonStreamingRewrite, setupClaudeMaxStreamingHook calls
from antigravity_gateway_service.go. These symbols are not yet
available in upstream/main.
Replace process-memory sync.Map + per-model runtime state with a single
"AICredits" key in model_rate_limits, making credits exhaustion fully
isomorphic with model-level rate limiting.
Scheduler: rate-limited accounts with overages enabled + credits available
are now scheduled instead of excluded.
Forwarding: when model is rate-limited + credits available, inject credits
proactively without waiting for a 429 round trip.
Storage: credits exhaustion stored as model_rate_limits["AICredits"] with
5h duration, reusing SetModelRateLimit/isRateLimitActiveForKey.
Frontend: show credits_active (yellow ⚡) when model rate-limited but
credits available, credits_exhausted (red) when AICredits key active.
Tests: add unit tests for shouldMarkCreditsExhausted, injectEnabledCreditTypes,
clearCreditsExhausted, and update existing overages tests.
