Research direction

No source file or test is named. Reproduce the formatting problem using debug 4.3.4 and the example involving an unused %s; trace the logging and timestamp formatting path. Done means unused format specifiers remain literal and do not consume the inserted timestamp.

Written by the indexing model from the issue text.

Description

As detailed in an issue in our tool, when unused, a %s specifier will catch the timestamp inserted by this package.

Example:
Notice the second line of regular text and the first of debug's output.
