The one-instance-per-repository tenet does not scale to a second
repository on a webspace (second service, port, tunnel, UI). Step 22
plans the revision in five sessions: ADR 0009 + instance registry and
key-ownership split, a RepoContext refactor with unchanged behavior,
watcher/executor multiplexing with per-repo error isolation, repo-scoped
routes and UI with single-repo back-compat, and the mih34 rollout with
Werkbaum as the second repository. Guiding idea: the repository stays
self-contained (state in its own .git/werkator), the instance is only
an aggregator — adding a repo is a registry entry, never a migration.
