As a result, distinct authenticated Matrix accounts can normalize to the same authorization identity. A Matrix participant controlling a colliding account identifier (a protocol-valid identifier that differs from the configured one only by characters OpenClaw case/Unicode folds; display-name matching is not required) can inherit allowlist, owner-command, exec-approval, or plugin-approval authority configured for another account.
