What/Why
Follow-up for WBC-1051: after a SQL connection is lost, report the backend's observed session status and recorded first failure without delaying cursor errors or shutdown.
This is a stacked draft on
codex/wbc-1051-disconnect, the head of upstream PR #74. Its diff contains only diagnostics. It is hosted in this fork because upstream branch creation is unavailable. After wherobots#74 merges, this commit can be proposed against upstream main. Deploy the companion session-status backend changes before enabling/releasing this follow-up.How
Deliver cursor failures first, then schedule a best-effort diagnostic log correlated by session ID. Diagnostic details do not modify already-delivered exceptions. Explicit close and direct connections without a status URL do not trigger lookups.
Share in-flight/recent requests by exact URL and a digest of the credential/header context. Limit each process to four daemon workers and 128 registry entries, retain completed attempts for 30 seconds, and add up to 500ms of worker-side jitter. No retries or waiting on the caller; stalled requests retain their worker slot and further optional requests are skipped at capacity.
Use a one-second HTTP socket timeout, disable redirects, stream at most 64KiB, and bound status and failure-message fields to 128 and 4096 characters. Log lookup and thread-start failures at DEBUG without request credentials or arbitrary exception text. Per-process sharing doesn't deduplicate across processes.
