New forwarding methods on GatewayService for Anthropic platform groups:
- ForwardAsResponses: accept Responses body → convert to Anthropic →
forward to upstream → convert response back to Responses format.
Supports both streaming (SSE event-by-event conversion) and buffered
(accumulate then convert) response modes.
- ForwardAsChatCompletions: chain CC→Responses→Anthropic for request,
Anthropic→Responses→CC for response. Streaming uses dual state machine
chain with [DONE] marker.
Both methods reuse existing GatewayService infrastructure:
buildUpstreamRequest, Claude Code mimicry, cache control enforcement,
model mapping, and return UpstreamFailoverError for handler-level retry.
Empty text blocks inside tool_result.content were not being filtered,
causing upstream 400 errors: 'text content blocks must be non-empty'.
Changes:
- Add stripEmptyTextBlocksFromSlice helper for recursive content filtering
- FilterThinkingBlocksForRetry now recurses into tool_result nested content
- Add StripEmptyTextBlocks pre-filter on initial request path to avoid
unnecessary 400+retry round-trips
- Add unit tests for nested empty text block scenarios
The settings form contains multiple <input type="url"> fields that lack
a name attribute. When a field value fails browser URL validation, the
browser silently blocks form submission without showing an error — no
network request is made, and the user sees no feedback.
Root cause: HTML5 form validation requires a focusable element with a
name attribute to surface errors. Without it, validation fails silently.
Fix:
- Add novalidate to the <form> to disable browser-native URL validation
- Add an isValidHttpUrl() helper in saveSettings() to replicate the
same checks the backend performs
- Optional URL fields (frontend_url, doc_url): auto-clear invalid values
instead of blocking the save, matching backend behaviour (these fields
accept empty string without error)
- purchase_subscription_url: block save with a clear error message when
enabled + invalid; auto-clear when disabled to prevent the backend 400
"Purchase Subscription URL must be an absolute http(s) URL" error

LegacyPrintf uses inferStdLogLevel() to infer log level from message
text. Any message containing the word "error" is classified as ERROR
level, causing the entire signature-retry recovery flow (which succeeds)
to produce spurious ERROR log entries.
Changes:
- Remove noisy [SignatureCheck] debug logs inside isThinkingBlockSignatureError
that were logging every detected signature check as ERROR
- Change retry-start log to WARN level via [warn] prefix
- Change retry-success log to INFO level by removing "error" from message

The quota reset mechanism is lazy — quota_daily_used/quota_weekly_used
in the database are only reset on the next IncrementQuotaUsed call.
The scheduling layer (IsQuotaExceeded) correctly checks period expiry
before enforcing limits, so the account remains usable. However, the
API response mapper reads the raw DB value without checking expiry,
causing the frontend to display cumulative usage (e.g. 110%) even
after the reset period has passed.
Add IsDailyQuotaPeriodExpired/IsWeeklyQuotaPeriodExpired methods and
use them in the mapper to return used=0 when the period has expired.
