Anthropic OAuth/setup-token accounts now expose a Fable-only 7d window in
429 responses (anthropic-ratelimit-unified-7d_oi-*). Previously, a 429
triggered solely by this window fell through to the legacy path and marked
the whole account rate limited (picking the sooner 5h/7d reset) even though
5h/7d were still "allowed".
Backend:
- HandleUpstreamError: when only 7d_oi is rejected/exceeded, set a
model-level rate limit (scope "claude-fable-5") and skip account-level
SetRateLimited / session-window rewrite / temp-unsched entirely.
Real 5h/7d exhaustion keeps the exact legacy account-level behavior.
- modelRateLimitKeysForRequest: append the Fable family scope for any
mapped Anthropic model containing "fable", so claude-fable-5[1m] and
other variants are excluded from scheduling together.
- Passive sampling: collect 7d_oi utilization/reset into Extra
(passive_usage_7d_oi_*), including from the 429 response itself so the
usage bar doesn't freeze at a stale value during the limit window;
cleared on 5h window reset like the existing 7d keys.
- Usage API: new seven_day_fable window in UsageInfo. GetPassiveUsage
builds it from passive samples; active queries parse the upstream
seven_day_overage_included field (claim name from the
representative-claim header) and fall back to passive data when the
upstream usage API doesn't return it, so the active-query button keeps
the bar populated. seven_day_sonnet handling is preserved unchanged.
Frontend:
- /admin/accounts usage cell renders a "7d F" (amber) progress bar next to
the existing 5h / 7d / 7d S bars for Anthropic OAuth/setup-token accounts.
