commit-hygiene sweep: (1) the #170 L4STEAMNET.h contract comment never landed in 2fe58b8 -- the git add used the lowercase filename and the case-mismatch left the tracked (uppercase) path unstaged, silently; (2) the gauges-hud #172 correction was a silent no-op -- a python str.replace whose multi-line needle didn't match printed 'corrected' anyway. Both applied for real now (verified by grep, not by exit code). Note the pattern: two silent tool no-ops in one evening -- verify edits by READING the result, not by the tool's success message
