The stack's account of a failure was scattered across four writers in three processes and reachable only from a terminal, so anyone running the app from a launcher had no way to see why something did not work, and no way to attach that account to a report. The console tails the file the host assigns and filters it by domain, severity and text, with an export for the whole file or for exactly what the filters pass. Every failure the backend reports now goes to the log as well as the strip, through one reporter, which is also what stops a reason the module could not supply from rendering as a trailing colon. Only a bounded window of the file is held, shared out between domains rather than kept strictly newest first, and a domain gives up its ordinary lines before its severe ones. A writer producing thousands of lines a minute would otherwise push every quieter one out of reach within minutes, leaving a filter chip counting lines nothing could show and a header counting errors that were no longer there. What a line says about itself outranks what relayed it, so a severity the writer stated beats the pseudo level the host stamped, and a field naming a module beats the innermost scope beside it.
