nodes_log

var (
	LogInfo  = newLogNode("log.info", slog.LevelInfo)
	LogWarn  = newLogNode("log.warn", slog.LevelWarn)
	LogError = newLogNode("log.error", slog.LevelError)
)

LogInfo, LogWarn, LogError emit a structured line at the matching slog level and return the input unchanged. The message field, when present, becomes the slog message; every other field becomes an attribute after passing through redact.Map, which masks any field whose name looks like a credential. The input map itself is never mutated — the same value flows downstream unchanged.
