Transcript save errors now name the underlying system error, so a failed write says why.
What's wrong with this entry?
Errors saving transcripts carry the underlying operating-system error code and a telemetry code in their message, so a failed append, move or folder creation identifies its cause.
- A folder-creation variant was added alongside the existing append and move errors.
- A check that withholds an append when the target file is missing now reports "onlyIfExists stat failed (…) — append withheld".
transcript storage folder creation failed
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
