-- Built-in @verifierbot: the applicant front door for THIRD-PARTY verification
-- (core.telegram.org/api/bots/verification).
--
-- This is the first verifier bot of a deployment, shipped so the feature has a
-- working reference: it collects applications for its own icon+description mark
-- and reports the operator's decision back to the applicant. It is deliberately
-- NOT a second way to get the platform checkmark -- @verifybot (0153) owns that
-- mechanism, and the two never read each other's state.
--
-- verified = false on purpose. The official flag is granted by the operator to
-- peers that passed platform review; a verifier bot carrying it would blur exactly
-- the distinction this bot has to explain to every applicant. What makes this
-- account a verifier is a row in bot_verifier_settings (0155), which an operator
-- grants by hand in the admin panel -- never this migration: seeding verifier
-- status here would hand out a badge printer with the schema.
--
-- Seeded rather than created lazily on first message so the username is occupied
-- from the moment the schema is current: peer_usernames.username_lower is the only
-- thing standing between a reserved bot handle and an ordinary user claiming it,
-- and a lazily created account would leave that window open.
--
-- access_hash is double-written with domain.VerifierBotAccessHash; the two must
-- never drift, exactly as for the other service bots (0044, 0045, 0047, 0153).
--
-- The peer_usernames insert carries the multi-username registry columns added in
-- 0149, so the handle occupies the editable slot.
