When is a SaSame plan honestly purchasable?

We don't turn a price into something you can actually buy until we can deliver on what checkout promises.

Every plan goes through the same stages, always in this order (the only shortcut allowed is retiring a plan early):

Approved price → Tested internally → On sale → Retired

• Approved price — the owner has signed off on a price, but there's no real payment set up yet. Not for sale. Public pages must say so clearly.
• Tested internally — we've built the payment and delivery process and tested it end to end using fake payments. Still not for sale with real money.
• On sale — a final check has been done: real payment is wired up, the legal terms are published, and we've verified what actually happens after someone pays. This is the only stage where a plan can be sold.
• Retired — no longer sold. We keep the history; we don't delete it.

A plan can never be marked "on sale" if we don't yet know what happens after someone pays for it — that rule has no exceptions.

Technical note: internally these stages are recorded as a price_state value of APPROVED_NOT_LIVE, TEST_MODE, LIVE or RETIRED. You may see these exact labels in API responses or developer documentation.

None of these, on their own, make a plan purchasable or count as real revenue: a test-mode checkout, an approved price, a payment record sitting in our system, or one successful build. Only reaching the "on sale" stage above does.
