Function createLogChannels

createLogChannels(
logger: ILogger,
options?: { render?: LogRenderer },
): LogChannels
Builds the log / warn / error channels for a run context.
Parameters
- logger: ILogger
  The backing sink. ConsoleLogger writes out; BufferLogger collects (the MCP path).
- Optionaloptions: { render?: LogRenderer }
  - Optionalrender?: LogRenderer
    
    Optional renderer for SDK objects - see LogRenderer.
Returns LogChannels

Remarks
Ordering is preserved across the sync/async mix: an entry that needs no rendering is written immediately unless an earlier entry is still rendering, in which case it queues behind it. So a plain log('done') stays synchronous (the CLI streams it) and log(stats) never arrives late.

A promise argument is awaited and logs as the value it settles to, in call order like any other async entry: log(sheet.evaluate('=SUM(A:A)')) prints the result. A rejection prints as [rejected] … on the same line.
