# Bridgev2 permission values are: block, relay, commands, user, admin.
# The old Python bridge had different levels (relaybot, user, puppeting, full, admin).
# `user` and `admin` still exist in both but with different semantics (the new `user` is
# equivalent to the old `full`/`puppeting`). `relaybot`, `puppeting` and `full` don't exist
# in bridgev2 and will cause the bridge to reject its config at startup.
#
# We check the fully-merged configuration (not just `matrix_mautrix_telegram_bridge_permissions`)
# because users commonly override permissions via `matrix_mautrix_telegram_configuration_extension_yaml`,
# and those overrides would otherwise slip through validation.
- name: Fail if bridge permissions still reference legacy Python-bridge permission levels
  ansible.builtin.fail:
    msg: |-
      Your final mautrix-telegram configuration contains a `bridge.permissions` entry with
      value `{{ item.value }}` (for `{{ item.key }}`). This was a permission level in the legacy
      (Python) mautrix-telegram bridge but is not valid in the bridgev2 rewrite shipped in v0.2604.0
      — the bridge would reject this at startup.

      Valid values are: `relay`, `commands`, `user`, `admin` (plus `block`).

      Rough mapping from the old levels:

        relaybot  -> relay
        user      -> user (semantics changed: this now grants full puppeting, like the old `full`)
        puppeting -> user
        full      -> user
        admin     -> admin

      See https://docs.mau.fi/bridges/general/permissions.html and the bridge's example config
      for details. Update either `matrix_mautrix_telegram_bridge_permissions` or the `bridge.permissions`
      section inside `matrix_mautrix_telegram_configuration_extension_yaml` — whichever you use.
