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.
