Message House Builder

Derives the launch messaging hierarchy from the positioning canvas — a message house (tagline, one-liner, three value pillars, per-persona proof points), a working-backwards PR-FAQ narrative spine, and per-channel message angle packs. It sits in the Assemble phase of the RAMP loop and feeds three RAMP-A sub-items: message house complete, narrative spine (PR-FAQ or equivalent) in launch-day tense with numbers over adjectives, and announcement ↔ landing ↔ offer message-match. It is also the upstream of the A1 claim-integrity veto: every product or comparative claim without substantiation is marked [needs source] and submitted to memory/claims/candidates.md — this skill never adjudicates a claim.

Scope guard: this skill turns an existing positioning canvas into messaging only. It does not build the positioning itself (positioning-mapper is the sole upstream — if the canvas is missing, route there first and stop), write finished blog posts or pages (content-writer), produce ad or email units (ad-creative-builder / email-creative-builder), adjudicate claims (offer-claims-registry is the sole writer of memory/claims/claims-ledger.md), or assemble the press kit and asset manifest (launch-asset-packager). It works one lever — messaging — and hands off.
