check / check (push) Successful in 12m29s
The startup banner moves from stdout to stderr, so a `completion` script, a `config get` value and the hidden `__complete` command print only their own output. `--quiet`, `--cron` and `--json` still suppress it. A failing `remote info`, `prune` or `snapshot remove` under `--json` now reports its error on stderr. Their reporters returned early under `--json`, so the failure reached neither stream. `snapshot verify --quiet` writes no report. A failure is still returned and printed on stderr, with the same exit status. Judgement call: the banner's stream, posted on the issue for the owner. Model: opus-5-5
