Email + TXT + one Start tap

An executive without Telegram can still register the entity. Binding is an invite deep link, the bot never cold-DMs.

01, Entity publishes

Owner signs in with email, creates a firm or individual, proves domain via _verify3 TXT, or founding review.

02, Representative binds

Owner sends an invite link. They tap Start in Telegram. The user_id is stored, never just the handle.

03, Owner authorizes

One action on the website. The bot never authorizes, only the entity does. Revoke works the same way.

04, Anyone checks

Forward a DM to @TiedToBot. Username lookup exists but is labeled weaker, it reads the cache.
