Claude Code Pro/Team users hit a 429 cascade where every Claude account
got marked rate-limited for only a few seconds, retried, hit 429 again,
and the cycle exhausted all accounts until the 5h subscription window
finally reset. Root cause: Anthropic OAuth 429 bodies carry phrases like
'Usage Limit Reached' or 'Claude Pro usage limit reached' that don't
contain the word 'quota'. classifyErrorText fell through to
RATE_LIMIT_EXCEEDED with the OAuth ~5s base cooldown.
Three targeted changes in open-sse/services/accountFallback.ts:
1. classifyErrorText: recognize the Anthropic OAuth phrases ('usage limit
reached', 'claude pro usage limit', 'you've reached your usage limit'
and variants) and return QUOTA_EXHAUSTED.
2. checkFallbackError: new branch that, when the classifier flags
QUOTA_EXHAUSTED for a non-credits/non-daily case, applies a deliberate
1h cooldown (subscription quotas need real time to reset; the existing
COOLDOWN_MS.paymentRequired is only 2 minutes).
3. parseRetryFromErrorText: parse absolute ISO 8601 timestamps in the
body ('Try again at 2026-05-17T10:00:00Z', 'Please wait until ...').
When present, honor the upstream's stated recovery time instead of
the 1h default.
Cross-provider fallback for direct (non-combo) calls remains a separate
feature — operators wanting that should route Claude through a combo
that includes openrouter/claude or another fallback target.
