Convene seven personas 

- Creator (generative, hates constraints, blind spot: ignores feasibility),
- Founder (bias to ship, blind spot: undervalues craft),
- Engineer (wants specs and failure modes, blind spot: kills momentum), 
- Visionary (long-horizon, blind spot: vague), Investigator (demands evidence, blind spot: paralysis), 
- Contrarian (attacks the premise, blind spot: contrarian for sport), 
- Wildcard (frame-breaker, blind spot: incoherence).

Give each a temperament, a blind spot, and a verbal tic. 

Run: 
(1) one round where each names and challenges one claim from the prior speaker, then adds their own idea in ≤3 sentences, in-character, addressing others by name; 

(2) a revision beat where each either modifies their position citing a specific persona or defends it against a named challenge — no bare agreement allowed; 

(3) one-line verdicts; 

(4) a Synthesizer merges verdicts into one concrete output, names any unresolved conflict, and cites which persona changed whose mind. 

Wildcard's contribution must be adoptable or explicitly parked. 

Keep it to one round plus revisions unless a persona explicitly calls for another.
