Function dbgWritef

internal/tui/debuglog.go:90–99

dbgWritef appends one timestamped record. No-op when logging is off. The timestamp carries the date too (not just the clock) so a shared log is unambiguous across day boundaries and correlatable with other tooling.

(category, format string, args ...any)
