STOP-765: counter 2 not receiving registrations (camp 454)
STOP-774: X-ray/TrueNat order never created when the screening is saved while the tablet cannot reach the hub (camp 458)
Why
A new STOP-TB tablet's first changes-feed download needed about 235 pages (25 beneficiaries each) and took 20+ minutes of uninterrupted pulling, which camp Wi-Fi and Android rarely allow. Tablets that never finished it never saw other counters' registrations.
STOP-774: the tablet placed X-ray/TrueNat orders with its own order/push right after saving a screening. With the hub unreachable at that moment the order was marked FAILED on the tablet only and never retried, and the registrar cannot open the X-ray/TrueNat screens to retry it (camp 458: 25 of 28 referred screenings on 4 Nov had no order).
What
WorklistPagePrefetch.addressesForRegIds: mapping + address rows for a whole page in two queries.
BeneficiaryServiceImpl.getBeneficiaryRecordsByRegIds uses it; the old per-row lookups remain as the fallback.
StopTBSyncServiceImpl.MAX_BENEFICIARIES_PER_PAGE: 25 → 100. The per-beneficiary FHIR call and identity lookups that justified 25 were already replaced by page-level prefetch.
STOP-774, the hub creates referral orders:
StopTBReferralOrderService: after a nurse/tbScreening/save commits, creates XRAY_CHEST / MTB orders for today's referred screenings (referredForDigitalChestXray, referredForSputumCollection) through createAndPushOrderAsSystem, on one background thread so device timeouts never hold up screening sync. Patient name/DOB/sex come from the hub's identity tables.
Sweep every 2 minutes (diagnostic.referral-sweep.tick-ms, default 120000): this van's referred screenings from today that still have no order.
Skips a beneficiary with an order of that type created today (any status, so a FAILED device push stays with the nurse's Retry) or an open/completed one, same as the existing dedup. Only screenings dated today create orders.
Runs only on a camp hub (stoptb.van.id set); central never sends device orders.
Each changes-feed page reports createsReferralOrders (true on a camp hub); the tablet stops pushing screening orders only once it sees it.
Also: feed beneficiary records are built from the requested registration's mapping, not the newest mapping at the address, so a shared address ID can no longer drop a record (CodeRabbit).
Tests
Sync tests pass locally except StopTBSyncCoverageTest.everyMappedTableIsSyncedOrDeliberatelyNot, which fails identically on untouched release-3.12.1 (badge/notification/general check-up tables not classified); unrelated to this change. StopTBReferralOrderServiceTest (7 tests) passes.
Pairs with STOP-TB-App #347 (release-2.3.1): feed-only reads, and the screening form no longer pushes orders in camp mode. Either can go first: a tablet keeps pushing orders until its hub reports createsReferralOrders.
TB screenings flagged for chest X-ray or sputum collection can trigger referral orders automatically when camp configuration allows it. Duplicate and outdated referrals are skipped.
Performance Improvements
Beneficiary address information is retrieved more efficiently, with a fallback when the faster lookup is unavailable.
Worklist pages can process up to 100 beneficiaries at a time, increased from 25.
Bug Fixes
Beneficiary records are matched to the requested registration when available, reducing mismatches in address information.
The change adds asynchronous chest X-ray and sputum referral-order processing for TB screenings, including a scheduled sweep. It also adds registration-aware beneficiary address lookup with a per-registration fallback, raises the beneficiary page cap from 25 to 100, and adds a camp-configuration flag to sync pages.

saveNurseTBScreening collects referral flags and calls the referral service once per batch. Sync pages include a camp-configuration referral flag. Tests cover order requests, patient fields, duplicate suppression, failure handling, camp configuration, and sex mapping.
addressesForRegIds retrieves addresses in input registration order using the newest mapping with a non-null address. Beneficiary record building retains the registration association and falls back to per-registration lookups if batch retrieval fails.

The changes-feed snapshot capped beneficiaries at 25 per page because each one
used to cost several identity lookups and a FHIR call. Records are now built
with one query per table for the whole page (WorklistPagePrefetch, health IDs
read locally); the remaining per-beneficiary mapping and address lookups in
getBeneficiaryRecordsByRegIds are batched too, with the old per-row queries as
the fallback. Raise the cap to 100 so a new tablet needs a quarter of the
pages for its first download.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Do not retry a database outage as per-beneficiary lookups.
If the batch query fails because the identity database is slow or unavailable, this catch starts up to two more queries per registration ID against that database. Limit the fallback to failures specific to the batch implementation. Let connection and timeout failures reach the feed so the tablet can retry the page. Based on learnings, catch the specific exceptions that warrant fallback rather than generic Exception. (raw.githubusercontent.com)

The tablet placed these orders with its own order/push right after saving the

notACampHubDoesNothing does not cover the configured-camp path of createAfterCommit or sweep.
The tests cover createOrders and the disabled case. They do not cover the sweepRunning reset in sweep, or the empty-referrals early return. This is a coverage gap on the new scheduled path. Add a test where findReferredSince returns an empty list and a second sweep() call still queries the repository. That test would prove the flag is reset.

Each feed page now carries createsReferralOrders (true on a camp hub). The
tablet stops placing screening referral orders itself only after it sees this
flag, so a hub older than this release keeps getting the tablet's push and no
referral is lost if the app is updated first.

Feed beneficiary records were built from the newest mapping at each address.
When two registrations share an address ID, that mapping could belong to the
other registration, so the requested record was missing and the feed moved
past it. The registration ID now travels with its address, the record is built
from that registration's mapping, and the prefetch loads that mapping's rows.

A screening that syncs on a later day than its visitDate never gets an order. Will the UI have a Retry button for it?
What the code does today: both paths only handle screenings with visitDate from today (screenedToday, findReferredSince(... startOfToday())). If the screening reaches the hub a day later, no order is ever created, and nothing records that it was skipped.
Retry doesn't help here. /diagnostic/order/retry only restarts polling on an order that already exists (retryPoll). With no order, there's nothing for it to retry.
The only way to create the order is /diagnostic/order/push. The nurse could call it from the X-ray/TrueNat screen, but only if the UI shows that beneficiary there. The registrar has no access to those screens.
How is it decided which orders to create? For example, should a pregnant beneficiary only get the MTB order and not X-ray?
What the code does today: only the two flags on the screening decide it. referredForDigitalChestXray creates XRAY_CHEST, and referredForSputumCollection creates MTB. Nothing on the hub checks pregnancy, age or anything else.
The UI draws its cards from the order status API. If the screening is done but no order exists, nothing comes back for that beneficiary. How will the UI handle that?
What the code does today:
GET /diagnostic/order/getBeneficiariesByStatus?orderType=... returns beneficiary IDs in five lists: awaitingProviderResult, completed, failed, closed and awaitingManualEntry.
Correct, the hub only creates orders for screenings dated today (screenedToday, findReferredSince(startOfToday())). That is deliberate: an order goes to a device for a patient who is at the camp now, and a beneficiary screened on an earlier day has usually left.
Recovery is the nurse's Retry Referral button, not /order/retry. In the app that button is RETRY_PUSH → AllBenViewModel.retryTest → TBRepo.createOrder → POST /diagnostic/order/push, which creates the order. A referral with no status and no order id falls into that branch on the nurse's card (BenListAdapter). The registrar cannot do it, which is expected; it is a nurse action.
2. Which orders are created (e.g. pregnancy)
The rule lives in the app, and the hub follows the two flags it receives. The screening form sets them (TBScreeningFormViewModel.initializeDiagnosticsAndPush):
So a pregnant beneficiary gets MTB only, no X-ray. saveNurseTBScreening stores both flags and StopTBReferralOrderService creates exactly those orders. Keeping the rule in one place is intentional.
3. Cards when no order exists
With the changes feed active (camp hubs), the app does not call getBeneficiariesByStatus; cards are drawn from the local diagnostics rows the feed fills. A referral with no order is still shown. Two changes in STOP-TB-App #347 tidy this up:
4fd4de78: on a hub that creates referral orders, the screening form no longer writes a local PENDING placeholder with no order id (it was never replaced if the hub made no order, and differed from other tablets).
ac38017d: for 5 minutes after the screening (the hub creates orders on upload and re-checks every 2 minutes), the card shows a disabled "Order being created"; after that it shows "Retry Referral". A Retry tapped while the hub is also creating the order is safe: createAndPushOrderLocked takes the per-beneficiary lock and returns the existing order.
Without the feed (older hub), getBeneficiariesByStatus simply has no entry for that beneficiary, so the local row and the card stay the same.
The app works out the referral. When the registrar submits, the app sets two flags on the screening from pregnancy and symptoms (TBScreeningFormViewModel.kt:264-271): referredForDigitalChestXray and referredForSputumCollection.
The flags go up with the screening. The hub stores them as they are, in the tb_screening table (StopTBServiceImpl.java:283-284).
The hub creates orders from the flags alone. StopTBReferralOrderService creates an X-ray order if the X-ray flag is true and a TrueNat (MTB) order if the sputum flag is true. Both the after-save trigger and the 2-minute sweep (findReferredSince) read only those flags.
