Decision sorb, after diagnosing why @apo could not reach the wiki. apo logs in
fine; the account exists since 2026-08-16 and was used again today. It is in no
group, and wiki-anwender has zero members, so the wiki is effectively admin-only
and every non-admin who ever tried met the same wall.
Three deliberate settings compose into a dead end: OIDC self-registration creates
the account, autoEnrollGroups is empty so it gets no group, and Guests was stripped
to no permissions while the only rule for home belongs to wiki-anwender. Default
deny then applies to every path including the start page - the user sees nothing
rather than a reason, and at the current log level nothing records the attempt
either. Same class as the mrtc outage: healthy, green, unusable, silent.
The issue asks for a decision rather than assuming one: auto-enroll into
wiki-anwender (the population is already curated by the invitation token, and
betrieb/* stays admin-only through default deny), or keep per-person curation and
make the dead end speak. Acceptance is a real login, not a config diff.
