F1 fixed in da1f0ceda, with the federation acceptance red and green runs and
the script suite results. F2: the invalid-proxy-context BundleError is raised
at launcher.mjs:569, outside the try at :655, so :686 never sees it;
fromSession maps it at :1199 and launchPm rethrows it at :1215.
Append-only R2 section: correction to R1's evidence, the two causes of the
53 cli failures, items 1 to 6 with their tests, RED, hermetic and GREEN
tables, five killed mutants on 39eadf8ba, and the F1, F4 and F2 docs
follow-ups.
