Product

Create or refine a product contract with the user's authority.

The contract works because it forces every claim into evidence or labeled aspiration; if a reader cannot tell which is which, the document has failed.

1. Inspect existing product, README, goals, release, and evidence sources.
2. Ask only for decisions that cannot be grounded safely from those sources.
3. State mission, users, pains, value, differentiation, and non-goals.
4. Separate evidence from hope under two required headings. Put every grounded claim under ## Proven, each carrying a resolvable citation (a README, release, test, or evidence source). Put unproven hopes, evidence gaps, and not-yet-measured success signals under ## Assumptions. A claim that cannot cite a source belongs under ## Assumptions, never ## Proven.
5. Preserve an existing PRODUCT.md unless the user authorizes replacement.
6. Return the document to the caller; Plan may use it as intent context.
