1effect/LogSpan#LogSpan:
2 replacement: "readonly [label: string, timestamp: number]"
3 note: "The module was removed. Active log spans are tuples in References.CurrentLogSpans; ordinary callers should prefer Effect.withLogSpan."
4effect/LogSpan#make:
5 replacement: "[label, startTime] as const"
6 note: "Construct the tuple directly, or use Effect.withLogSpan so Effect obtains the timestamp and scopes the span."
7effect/LogSpan#render:
8 replacement: "custom tuple formatter"
9 note: "No public standalone renderer remains. Built-in loggers format span tuples internally; custom formatters can render label and elapsed milliseconds themselves."
