+| **v1.15.8** | 2026-07-19 | **Bugfix:** mon HTML filter JS — drop literal box-drawing / `\-` regex that caused Python SyntaxWarning (and weird glyphs in suite logs); use Unicode code-point loop instead. |
 | **v1.15.7** | 2026-07-19 | **Bugfix:** mon HTML — do not paint «perf/ladder summary» as SUMMARY header (restore 2 INFO lines); drop converter SyntaxWarning/noise from public log; «wrote» on stderr; host-agent PYTHONWARNINGS for convert. |
 | **v1.15.6** | 2026-07-19 | **Bugfix:** aptdeploy ERROR jump list is self-contained — systemd httpd failures include before/after state, Result/SubState, failed units, and journal snippets (no more vague «see systemd lines»); ldd/--version errors embed concrete missing libs / exit output. |
 | **v1.15.5** | 2026-07-19 | **Bugfix:** devtesting CHF ladder — `ssh` was draining ladder stdin (only rung 1/23 ran → progress 45/98 then snap 52/52); use `ssh -n` + `mapfile`; incomplete ladder is WARN not false complete. |
