Gate every mutating action on `useOnline()`: the buttons disable, a notice explains why, and the `check`/`confirm` handlers bail on `!navigator.onLine` even if a stale render slips through.

Adds GET/PATCH /api/merchant/profile: GET serves a per-merchant unstable_cache-wrapped read tagged merchant-profile-
, and PATCH writes the update then calls revalidateTag(tag, { expire: 0 }) so the caller's next read is never stale. Other routes are left reading merchants live, since RLS scoping and settlement-signature verification must never act on a stale row.

Adds AccensaClient (packages/sdk/client.ts, exported from the new @accensa/sdk/client entry point so its @stellar/stellar-sdk dependency stays opt-in) with a contractId constructor option that defaults to Accensa's testnet ReceiptAnchor and can be overridden for a merchant-deployed instance, alongside rpcUrl/networkPassphrase to match. Documents the default-vs-custom tradeoff and RPC requirements in the SDK README. Closes #139 * fix(sdk): resolve rebase collision with the newly-merged AccensaClient Rebasing onto main picked up #257's own AccensaClient (an unrelated indexer HTTP read client re-exported from @accensa/sdk, added after this branch was created), which collided by name with the on-chain contract client added here.

Replace it with a clean reconciliation of the parallel-sweep streaming design and the batched inserts/webhook signatures: windowed onEvents consumer streams each completed ledger window, batches inserts per window in a transaction, fires webhooks after COMMIT, and advances the cursor to the sweep's sweptThrough boundary. Also fix the web DB integration tests, which failed against the CI postgres:15 service: - grant test_app_user USAGE/CREATE on the public schema and table ownership (PG15 no longer make public world-writable), run once up front to avoid racing concurrent catalog writes - coerce BIGINT ledger columns to Number (pg returns int8 as string) And apply Prettier to packages/sdk/index.test.ts. --------- Co-authored-by: Codebuff --- apps/web/src/app/api/sync/route.ts | 236 +++++++++++++++--------- apps/web/src/lib/db.integration.test.ts | 49 +++-- apps/web/src/lib/event-pager.test.ts | 160 ++++++++++++++++ apps/web/src/lib/event-pager.ts | 183 +++++++++++++++++- packages/sdk/index.test.ts | 2 +- 5 files changed, 527 insertions(+), 103 deletions(-) diff --git a/apps/web/src/app/api/sync/route.ts b/apps/web/src/app/api/sync/route.ts index dac4b6d..11b16d8 100644 --- a/apps/web/src/app/api/sync/route.ts +++ b/apps/web/src/app/api/sync/route.ts @@ -6,10 +6,24 @@ import { ensureSchema, getLastSyncedLedger, getSyncState, + setLastSyncedLedger, } from '@/lib/db'; -import { eventsToPaymentRows, insertPaymentsInTransaction } from '@/lib/insert-payments'; +import { + sweepLedgerRange, + parallelSweepLedgerRange, + PARALLEL_SYNC_THRESHOLD, + EVENTS_PAGE_LIMIT, + type EventPage, +} from '@/lib/event-pager'; +import { + eventsToPaymentRows, + chunkRows, + buildBatchInsertSql, + flattenRows, + PAYMENTS_BATCH_SIZE, + type PaymentRow, +} from '@/lib/insert-payments'; import { listMerchants, getMerchantFromRequest, type Merchant } from '@/lib/merchants'; -import { sweepLedgerRange, EVENTS_PAGE_LIMIT, type EventPage } from '@/lib/event-pager'; import { cooldownRemaining } from '@/lib/sync-status'; import { isAuthorizedCronRequest } from '@/lib/cron-auth'; import { createHmac } from 'node:crypto'; @@ -97,6 +111,43 @@ interface CooldownResult { retryAfterMs: number; } +/** + * Inserts `rows` in batches inside a single transaction. + * + * Mirrors `insertPaymentsInTransaction`'s batching but without advancing the + * sync cursor: the streaming consumer calls this once per completed ledger + * window, and the route advances the cursor to the sweep's final + * `sweptThrough` afterwards.

Failures are logged, optionally alerted, and surfaced in the response as `failures`, flipping `success` to false — which .github/workflows/sync.yml already treats as a warning worth surfacing, without disturbing the `syncedTo`/`skippedLedgers` contract that workflow depends on for merchants that did succeed.

Fixes gaps in hover states, borders, text colors, and button backgrounds that were inconsistent in dark mode. Closes #121 * feat: add rate limiting to public API routes - Integrate @upstash/ratelimit with Redis-backed sliding window - Apply 100 requests/IP/minute limit to /api/verify, /api/auth, /api/hook/* - Return 429 with Retry-After, X-RateLimit-Limit, X-RateLimit-Remaining headers - Extract client IP from x-forwarded-for / x-real-ip headers - Rate limiting runs in middleware before DB access Closes #131 * style(web): apply Prettier formatting to fix CI format check Prettier --check failed on dashboard/page.tsx, verify/page.tsx, and middleware.ts (all touched by the rate-limiting change). Reformat them so the format CI job passes.
