 ### B258 — `journalctl -p warning` shows nothing, whatever the daemon logged
 
-**Status:** Open
+**Status:** Fixed, not verified live
 **Found:** 2026-10-31, issue #53: the reporter ran `journalctl --user -u proton-drive.service -b
 -p warning`, as `docs/TROUBLESHOOTING.md` tells them to, and got `-- No entries --`.
 **Where:** `main` in `crates/pdfs-cli/src/main.rs`; `packaging/proton-drive.service`

 troubleshooting guide's filter hides all of them.
 
-**Fix.** Not done. When `JOURNAL_STREAM` says the output goes to journald, start each line with
-the `<N>` prefix for its level.
+**Fix.** When standard output is the journal stream (`JOURNAL_STREAM` names the same
+device and inode as fd 1), each line starts with the `<N>` prefix for its level, and ANSI colours
+are off. A terminal that merely inherited `JOURNAL_STREAM` keeps the plain format

+**Test:** `each_line_opens_with_the_priority_of_its_level` and
+`journal_stream_must_name_the_same_file` in `pdfs-cli`. On 2026-10-31, `pdfs diagnose` run with
+`RUST_LOG=debug` under `systemd-run --user -p StandardOutput=journal` stored its debug lines at
+`PRIORITY=7` and its report at 6.
