// Characterization of recordStreamingUsageStats — the per-request usage-stats persistence extracted
|
|
// from handleChatCore's onStreamComplete (chatCore god-file decomposition, #3501). Uses a real temp
|
|
// DB and polls usage_history (saveRequestUsage is async + fire-and-forget). Locks: the non-object
|
|
// usage guard, the streaming field mapping (status/success/ttft/errorCode), and a non-200 stream.
