hum persists stdout and stderr independently for every detached service. A small native sink rotates both streams and exits automatically when they close; CLI and TUI readers do not own the service pipes.

max_file_bytes: 10485760
rotated_files: 3
max_line_bytes: 65536
retention: 7d
redact_patterns:
- "(?i)(token|password)=[^ ]+"max_file_bytes bounds every active or rotated stream file.
rotated_files controls the retained generations, while retention removes
expired rotations when sinks start and rotate. max_line_bytes bounds display
buffers for unusually long or newline-free output.
Redaction patterns apply when logs are displayed; raw persisted files remain faithful to the original process output.

# Combined template tail
hum storefront all-services logs --lines 100
# Follow one service
hum storefront all-services logs api --lines 100 --followThe initial CLI tail reads a bounded amount from each stream and reports
truncation. In the TUI, scrolling pauses live follow, Home loads older pages,
End returns to the tail, / searches the loaded view, and c clears only the
view—not the files.
