pit: an ending can be bought and renewed

[ralyodio]

ENDING_PRICE_USD was $5 and charged by nothing. registerTld inserted a row and claiming was free and permanent — no term, no expiry, nothing to renew.

This is the lifecycle underneath that price: PRD 0005 §5's one-year term on a direct ending, plus the CoinPay checkout that starts one.

quoteTld        what an unclaimed ending costs        $5 × years, cap 10
quoteRenewal    what keeping one costs
openTldPurchase reserve it against other buyers
settleTldPurchase  hand it over, or extend the term

Modelled on the name flow, not invented beside it

Same shape and same reasons: keyed on the payment id so a webhook redelivery settles the same row; a conditional UPDATE to claim it, because CoinPay retries anything it never got an ack for and two deliveries both read pending before either write lands; a reservation that stops two people paying at once, with the UNIQUE constraint still the real arbiter at settlement.

An ending taken between checkout and confirmation is recorded refund_due and logged — real money against something the buyer can't have.

Renewals never shorten a term

Extends from whichever is later, the current expiry or now. Renewing early adds to what's left instead of throwing it away; renewing after a lapse doesn't backdate into the past. PRD 0005 R7. Both directions tested.

Grandfathering — deliberately not done

Both new columns are NULLable and every existing row keeps NULL. A NULL expiry means "no term recorded", which is what all ~250 endings claimed before today have, and isExpired reads it as not expired.

Backfilling an invented expiry would put a namespace on a clock its owner never agreed to. §21.8 wants a published grandfathering policy first — that's a decision, not a migration.

Claiming is still free. This adds the paid path; it doesn't switch the free one off. Doing that would break the bulk-claim flow mid-session and is a product call, not a refactor.

Tests

13, including the two races that cost money: a redelivered webhook, and an ending claimed in the gap. Full pwa suite green.
