Follow-up to the event-time proxy snapshot: every upstream attempt now carries attribution, the direct/unknown contract is enforced everywhere, and the queued upstream_errors array has hard bounds again. Attribution coverage - compact fallback retry helper and the streaming compact failover event now stamp proxy_id/proxy_name; the non-streaming SSE compact retry previously dropped its first attempt on `continue` and now records it - raw chat-completions stream truncation events (new on main) attributed - Anthropic/Bedrock transport errors get attribution inside the shared handleUpstreamTransportError helper, so all five callers inherit it - OpenAI first-output timeout takes attribution from the caller: HTTP callers pass the HTTP rule, the WS passthrough relay passes the WS rule (no managed proxy => unknown, never direct, because http.DefaultClient may honor environment proxies) Contract hardening - single opsUpstreamProxyAttribution returns (id, name) from one decision; a hydrated Proxy without a durable ID is unknown, not id=null+name - both normalizers (struct at append time, JSON on detail reads) enforce proxy_id==null <=> sentinel name; blank managed name => "proxy" - detail-read normalization edits only the attribution keys via sjson, so keys from older struct versions and stored key order are preserved Queue bounds - keep at most 256 attempts and ~512 KiB serialized per entry, newest first; the oldest retained event records dropped_earlier_attempts - attempts outside the 16-event body window trim url/message to 512 bytes - restore the empty-event drop rule, judged before the body window clears detail so older real attempts survive Tests cover each site above (managed proxy, direct, WS unknown), the normalizer invariants, key/order preservation, and the count/byte bounds.
