The import list reported a line count, which is the wrong axis: these
transcripts embed screenshots as base64, so one line can be a megabyte.
On this machine a 69 MB session has 3,427 lines while a 44 MB one has
6,792 — the number on the row said nothing about what continuing the
session would cost, and size is the only thing there that predicts it.
The session behind the 2026-08-29 incident was 65 MB across 13,000 lines,
a line count that looks unremarkable.
Shown beside the line count rather than instead of it, since a short file
of long lines is exactly the expensive case. Not warned about and not
marked: importing a large session is a choice somebody is entitled to
make, and flagging it would be the interface nagging about a decision
already taken.
