The previous session reported the new code green, but measured it with --no-cov (step 1 of finish_2026_08_24.sh passes that flag), so seven branches in the recovery path had never been exercised. Coverage was 99.78%. Most of the gap was the auto-recovery itself: whether healing succeeded, whether the retry after healing succeeded, and what gets recorded when it does not. That is the code which ran in production for the first time today, and none of its outcomes were pinned. Also covers the donor search on a machine with no ~/.config, siblings whose cache is readable but holds no usable token, and the two healthy paths that must stay silent — an always-on "this may be wrong" panel is one nobody reads. Writing the UI test surfaced that collect_source_findings is never empty for a fresh tmp_path, because an empty sync is itself a finding; the stub is there so the branch under test is "nothing to report". 1115 passed, coverage back to 100%.
