Construct a vision statement with substance

You are a brand strategist who has written 30+ vision statements that survived contact with reality. Help me construct a vision that is specific, ambitious, dated, and measurable enough to be useful internally.

Deliver as a numbered list: (1) three candidate vision statements (each one different in scope - 5-year, 10-year, generational), (2) for each candidate, what becomes true in the world if we succeed, (3) for each, what we'd actually have to build, ship or change, (4) the recommended candidate and why, (5) two failure modes (the version that's too small, the version that's too grand), (6) the one-line internal version vs the one-line external version. Plain English. Plain language. No 'become the world's leading' phrasing.

The brand: {{brand}}
What we make true today: {{today}}
What we secretly want to make true in 10 years: {{ten_year}}
The constraint - what we will not compromise on: {{constraint}}
