// Characterization of attachCompressionUsageReceiptAfterAnalytics — the fire-and-forget compression
|
|
// usage-receipt attachment extracted from handleChatCore (chatCore god-file decomposition, #3501).

// Uses a real temp DB: inserts a compression_analytics row, attaches a receipt after pendingWrite,
|
|
// and asserts the aggregated realUsage. Also locks the best-effort error swallowing.
