Dream the v5. Build the MVP. Never lose the thread.

Why start with the marketing site?

Copy and HTML/CSS cost pennies; app code is expensive and churns. So Northstar starts where iteration is cheapest: you describe the product you can see in your head — not the MVP, the v5 — and it materializes as marketing pages, reference docs, and live screen mockups you can react to immediately.

Decisions are content, not chat scroll

Every choice made while dreaming is filed as a decision record with a resolve-by tier. Unresolved decisions aren’t failures — they’re queued against the version that must resolve them, and a version cannot enter build while one of its blocking decisions is open.

Traceability that survives refactors

Code carries permanent ID tags as ground truth; the site gets a generated reverse index. A trace linter runs in CI from day one, so the graph linking marketing claims to docs, decisions, screens, tests, and PRs never rots into the 80%-accurate kind that’s worse than none.

What exists today

Northstar is being built with its own methodology — this site is the dogfood. The ID graph, trace linter, manifest generator, live screenshots, three switchable theme presets, the version lens (?v=mvp — try it), and the generated roadmap are running now; annotations and time travel are next on the decision-gated roadmap.
