The ownership repair added in e5b8de8c2 is not sufficient on every Ansible privilege-escalation setup. Git may still see a different effective owner after the checkout has been recursively chowned, as demonstrated by #5065.

Pass an exact, task-scoped safe.directory setting to all 56 server-side git tasks. Keep the ownership repair as well, because it remains necessary for filesystem permissions. The two controller-side theme checkouts already use the same protection.

The homeserver only reads appservice registrations on startup, and the
playbook only restarts it at the very end of a run. On the run which
first enables Meowlnir, bot provisioning therefore talked to a
homeserver still running without Meowlnir's registration, hitting
M_UNKNOWN_TOKEN and hanging indefinitely.

Provisioning now verifies the token upfront and restarts the homeserver
itself when needed, so a single run completes even when Meowlnir was
just enabled.

Asks the homeserver who Meowlnir's appservice token belongs to.
A 401 (M_UNKNOWN_TOKEN) response means the homeserver is running
without Meowlnir's appservice registration, which is the usual cause
of Meowlnir's "Failed to connect to homeserver" log messages.

Without a timeout, a request against an API which accepts connections
but never answers (e.g. Meowlnir stuck retrying against a homeserver
that rejects its appservice token) hangs the playbook forever instead
of failing with a usable error.

Meowlnir (https://github.com/maunium/meowlnir) is a Matrix moderation
bot which speaks the same policy-list protocol as Mjolnir and Draupnir,
but runs as an appservice and can override individual policies coming
from ban lists you do not control.

Bots and their management rooms live only in Meowlnir's own database —
nothing in its configuration file can declare one — so the role
provisions them through the management API from a declarative roster
(matrix_bot_meowlnir_bots_custom), applied under the
ensure-matrix-users-created tag. Management rooms may be declared or
created for you; bots and rooms no longer declared get pruned.

Wrapper scripts for driving the management API by hand are installed
to /matrix/meowlnir/bin.

Meowlnir re-runs its configuration upgrader in memory on every start,
so a literal `generate` value yields a new secret per restart. All
secrets are therefore rendered explicitly, validation rejects
`generate`, and the configuration directory is mounted read-only.

Draupnir and Meowlnir both want synapse-http-antispam, which the
playbook wires up to a single consumer. The wiring prefers Draupnir,
and both roles fail the run when each claims it.
