A till holds every bill in its own SQLite database and keeps it for
seven days after we acknowledge it, marking one synced only when its id
comes back in an ack. Everything here follows from that.
Silence is not acceptance, so a failing ingest publishes nothing at all
and the terminal simply sends again. A duplicate is a success, because
at-least-once delivery means a lost ack legitimately re-delivers bills
we already hold, and calling those failures would strand a day of
takings on the till. Deduplication is a unique index on the terminal's
UUID plus an advisory lock held for the transaction.
Bills land in pos_orders / pos_order_items rather than orders: a counter
bill carries a cashier, a terminal, a rounding adjustment, promos,
loyalty movement and a payment split that orders has nowhere to put, and
forcing one into the other loses whatever does not fit. Stock is *not*
split — a counter sale writes the same productstocks rows an app order
does, through helpers extracted from createOrderTx so the rule that
prevents overselling has one implementation rather than two.
GetRevenueSummary and GetSalesSummary were extended to union the new
table in; any new report has to remember the same.
Terminal health goes to Redis under a 90-second TTL, sharing the
instance the express backend uses. A heartbeat is a fact with an expiry
date: a till that loses power stops refreshing and ages off the board by
itself, where a Postgres row would need ~288k writes a day and a reaper.
Proven end to end against the live estate before commit: a bill over
HTTP and one over the real Mosquitto broker, the same bill three times
producing one row and one stock movement, and a heartbeat arriving on
the health endpoint. All probe data was removed afterwards.
Four things that only surfaced against real data. An unset jsonb column
failed the very first bill. Product SKUs are unusable as barcodes — 6,245
products share 93 SKUs and "1" covers 5,794 of them — against the till's
unique index, so barcodes fall back to the product id. A taxpercent of
-1 exists and would have put negative GST in a filed slab. And a product
with id 0 exists, which can never be billed and is now skipped.

The offline-sales import required one workbook per outlet and a store
picked in the UI. A merchant running several branches had to download,
fill and upload a file per branch, and the picker defaulted to the
tenant's first outlet — so an admin who never touched it silently
credited the wrong store, which no validation could catch because the
file and the selection agreed with each other.
One workbook now covers every branch. getsaletemplate takes locationid=0
(the default) to span the tenant, stamping tenantid, locationid and the
store name onto every row, and that row's locationid is what decides
which branch a sale is deducted from. The INNER JOIN on tenantlocations
confines it to outlets the tenant owns, so a template can never disclose
another merchant's catalogue.
uploadofflinesales accordingly takes locationid on each bill. The
locationid on the request itself becomes a scope constraint rather than
a destination: left at 0 the bills go where their rows say, and set to a
branch it pins the upload there and refuses anything else. That is what
holds a store user to their own store — the pin comes from their session,
so editing the locationid column in the spreadsheet changes nothing.
Every branch referenced is checked against the tenant regardless.
Branch context and catalogue are resolved once per branch and reused; a
workbook covering six outlets would otherwise re-run both queries for
every bill in it.
Duplicate detection is now per branch. Bill numbers only have to be
unique within a store, since counter books at different outlets
routinely restart numbering at 1, and treating a shared number as a
repeat would have silently dropped a real sale.
Verified against tenant 1087, whose two branches both stock product
6998 at 100 units: a single upload of two bills moved 1097 to 97 and
1135 to 95 independently; the same bill number at both branches imported
as two separate orders; an upload pinned to 1097 imported its own bill
and refused the 1135 one; a row naming another tenant's outlet was
refused; and re-uploading the file deducted nothing. All five test
orders were cancelled afterwards and both branches confirmed back at 100.

Order ids were duplicating in production: 160 distinct (tenant, orderid) pairs
are shared by more than one order, worst of them "1135-1" on 108 orders, and
every order tenant 1147 has ever placed is numbered "1147-1".
getSequenceno read MAX(seqno)+1 and updateSeqno incremented, both against
r.db rather than the order's transaction and separated by the whole order
insert. Two concurrent orders therefore read the same number before either
wrote, and an order that rolled back still consumed one. Three further
defects made it worse:
- A NULL orderseqno made COALESCE(MAX(orderseqno) + 1, 1) evaluate
NULL + 1 = NULL and fall through to a hardcoded "<tenantid>-1". The
increment then computed NULL + 1 = NULL too, so the counter could never
leave NULL and every subsequent order reused that same id.
- Tenants with several ordersequences rows (tenant 1135 has ~25) hit a
GROUP BY returning multiple rows, of which Scan kept the first
arbitrarily, while the increment updated all of them.
- A tenant with no row at all fell back to "<tenantid>-1" indefinitely,
because nothing ever created one.
nextSequenceNo replaces both functions with a single UPDATE ... RETURNING run
inside the caller's transaction, so the counter row stays locked until the
order commits and concurrent orders queue rather than collide. A NULL seeds
from the tenant's existing order count — at least as high as any number
already issued, so recovery cannot reissue a used id — the counter is pinned
to the tenant's lowest sequenceid so reads and writes address one row, and a
missing row is created on first use.
Verified against production data in rolled-back transactions: tenant 1147
(NULL) now yields 1147-9, 1147-10, ...; tenant 1135 (NULL plus duplicate rows)
1135-356 onward; tenant 916 keeps its 916-2024115209 subprefix format; an
unknown tenant creates its row and starts at 1. Eight concurrent allocations
produced eight distinct ids. Two real orders through the API returned 1147-9
and 1147-10, then were cancelled with stock restoring to its baseline.

products.productstatus is a per-product lifecycle field holding
"Active"/"Inactive". CreateProductStock overwrote it with "available" on every
stock receipt — an availability value written into a lifecycle column — which
destroyed the real lifecycle state of the rows it touched. 136 products now
read "available" and 12 "outofstock" with no way to recover what they were.
A single column on products cannot express availability anyway: the same
product can be stocked at one outlet and empty at another. That fact belongs
to productlocations.status, which SyncProductLocationStatus already derives
from the ledger, so the receipt path now updates only that and leaves
productstatus alone. UpdateProductStatus remains available as an explicit
admin operation; it is simply no longer called as a side effect of stock
movement.
GetProductCount counted available/outofstock off the same corrupted column and
returned near-nonsense as a result: across 6245 products it matched
'available' on 136 and 'outofstock' on 12, leaving 6097 — the real answer —
uncounted under "Active". It now derives both from the ledger, counting a
product available when it holds positive stock at any of the tenant's outlets,
so total = available + outofstock (6245 = 22 + 6223).

Stock shown in the console did not match the productstocks ledger, and two
product endpoints were failing outright. Every cause was on the read side or
in how the availability flag was maintained; the ledger writes themselves
(CreateOrder's "out" entry, cancellation's "in" entry) were already correct.
Read fixes, repositories/productRepository.go:
- GetProductStocks returned SQLSTATE 42803 on every call: bare a.tenantid /
a.stocktype / a.status under GROUP BY a.productid. The per-ledger-row
columns are now aggregated and the grouping covers the identity columns.
- FetchFilteredProducts filtered on an alias `e` that no query defines, so
every /getallproducts call carrying a locationid failed with SQLSTATE 42P01
instead of returning products.
- FetchFilteredProducts joined productlocations on productid alone and joined
a (productid, locationid)-grouped stock subquery on productid alone, so a
product carried by three outlets came back three times, each row showing
another outlet's quantity and status. Both are now tenant-scoped subqueries
collapsed to one row per product and scoped to the outlet when one is given.
- GetProductStocks and FetchFilteredProducts compared stocktype = 'in'
case-sensitively. Production holds 'in' and 'IN' both, so uppercase receipts
were silently dropped from the balance: one outlet reported 0 for a product
holding 50, another reported 0 for twelve products holding 200-840.
- GetStockStatement summed opening over stockdate <= CURRENT_DATE, making it
arithmetically identical to closing. The Inventory ledger showed the same
number in both columns on every row, which reads as stock never moving.
Availability flag:
productlocations.status was maintained by two different rules — the order path
derived it from the balance, the receiving path set 'available' on any "in"
entry regardless of the resulting balance. A partial restock that left the
balance at or below zero marked a product sellable, and a flag set by an old
order never cleared for stock that arrived by a route the API did not own.
Both paths now derive the flag from the live balance through one rule:
SyncProductLocationStatus (receiving side) and syncProductLocationStatus
(order side, inside the caller's transaction). ReactivateProductLocations is
replaced by the former; the service no longer filters refs by stocktype, since
the direction of the movement is no longer what decides the flag. A row that
has already drifted now repairs itself on its next ledger entry.
Verified against the live database: all four stock endpoints return matching
balances, /getallproducts no longer duplicates rows, and the flag sync was
exercised in both directions inside a rolled-back transaction.

The order-placement stock check (read available qty, then insert an "out"
deduction) had no row lock, so two concurrent orders for the same product
could both pass the availability check before either committed its
deduction, overselling the item. Locks each ordered product's
productlocations row with SELECT ... FOR UPDATE up front, in a fixed
(productid, locationid) order across all items so overlapping concurrent
orders contend for locks in the same sequence instead of deadlocking.
The store/branch QR code the app scans is just {tenantid, locationid} JSON, but the
onboarding response previously discarded the DB-assigned locationid, so the frontend
had no way to render a store's QR right after onboarding without a separate lookup.

Two gaps found while auditing the order/stock flow:
- Receiving stock via an approved stock request only updated
products.productstatus (a global per-product flag). A location
flagged outofstock by CreateOrder never got reactivated, since
nothing touched productlocations.status on the way back in.
CreateProductStock now reactivates the specific
(tenant, location, product) row to "available" for every "in"
entry, the counterpart to how it gets flagged out.
- getproductbyvariant returned no stock info at all, so the app could
only find out a product was unavailable from the 409 at order time.
It now accepts an optional locationid and, when passed, returns
live productstock (same SUM(in)-SUM(out) formula the order check
uses) and locationstatus per product. Omitting locationid keeps the
old response shape.
Added MOBILE_ORDER_VERIFICATION.md as a handoff doc for the mobile
team covering the expected request/response shapes and how to verify
their integration.

CreateTenantLocation hardcoded the new location and its auto-spawned
manager login to InActive regardless of what the caller sent (the
frontend already sends Active). AppLogin checks account status before
checking whether a password is set, so a new store's login could
never reach the password-setup screen — permanently stuck on
"Inactive Account. Contact admin."

CreateTenantUser copied the tenant form's fields onto the new
app_users row via copier.Copy, but the onboarding form never sends a
configid, so it defaulted to 0. AppLogin's GetUserByAuthname always
queries configid=1 for the web login, so any tenant onboarded through
this path was permanently unable to log in by email ("Email not
found") no matter what was typed. Set it explicitly, same as roleid.

issuperadmin on app_users (schema change already applied to the DB)
is now returned by AppLogin/TenantWebLogin's login response, gated
server-side rather than via a client-supplied roleid. Fixes the login
enrichment query (GetTenantUserById) to LEFT JOIN app_location instead
of INNER JOIN — a tenantless super-admin row was previously silently
dropped, so the login "succeeded" but returned an empty struct.
Also exposes createtenantuser on the web route group (was mob-only).
No repository changes were needed for location auto-provisioning:
GORM was already inserting the nested tenantlocations association on
tenant creation, it just wasn't reachable from the web.

subcategoryid is no longer required to import a catalogue product —
it's a display/grouping hint elsewhere (the codebase already has an
"Uncategorized" fallback for subcategoryid=0), so requiring it was
pure friction with no correctness payoff.
Fixes the category picker at the root: categoryid 2, which tenant
1135's real products actually use, has no row in productcategories at
all (not a filter bug — the master data is genuinely missing it).
Rather than inventing category master data, adds
GET /products/gettenantcategories, which lists categories a tenant's
own products actually use (falling back to a synthesized label when
the master table has no name), so the import category picker always
offers something real instead of an incomplete global list.
Also relaxes the subcategory lookup's tenant filter to include
unowned/global rows (tenantid NULL or 0), not just exact tenant
matches — categoryid 2's real subcategories carry no tenant at all,
so the strict filter was hiding them even when a tenant wanted one.

Adds a separate CatalogueDB (pgvector) connection alongside the main
nearledb, plus a new catalogue module (repository/service/controller/
routes) to browse it by brand, category, and keyword, with brand
optional so the whole ~237-product catalogue can be browsed unfiltered.
Adds the actual bridge: importing a catalogue product snapshots it into
the tenant's own products table (keyed on brand+catalogueid, since a
catalogue row's bare id is only unique within its own brand table),
then links it via the existing productlocations upsert. Re-importing
tops up stock and refreshes price instead of duplicating. Also adds an
imported-refs endpoint so the frontend can badge already-imported items
without diffing full product lists, and wires the new AWS S3 image
store used to resolve catalogue product photos.
Bumps Go/Docker to 1.24 for the AWS SDK dependency this needs.
