Method UpdateChatLastTurnSummary

coderd/database/querier.go:1233–1233

Updates the cached last completed turn summary for sidebar display. Empty or whitespace-only summaries are stored as NULL here so direct query callers cannot accidentally persist blank sidebar text. This intentionally preserves updated_at. The staleness guard relies on every new-turn query, such as

(ctx context.Context, arg UpdateChatLastTurnSummaryParams)

	// goroutine summary writes will be rejected as stale.
	// Two summary workers using the same freshness marker are last-write-wins.
	UpdateChatLastTurnSummary(ctx context.Context, arg UpdateChatLastTurnSummaryParams) (int64, error)
	UpdateChatMCPServerIDs(ctx context.Context, arg UpdateChatMCPServerIDsParams) (Chat, error)
	UpdateChatMessageByID(ctx context.Context, arg UpdateChatMessageByIDParams) (ChatMessage, error)
	UpdateChatModelConfig(ctx context.Context, arg UpdateChatModelConfigParams) (ChatModelConfig, error)
