## 2026-09-22 — Security hotfix, stage 1 — close the unauthenticated write paths

Branch `parity/security-hotfix`. Authorised by the user's rulings D7, T1–T3.

### 1. Ledger routes are admin-only (SEC-09)

- **What:** removed the controller-level `@Public()` from `AccountingController`
  and gave each route a rid: `wallet.list` (balance), `wallet.charge`
  (reconcile), `document.create` (both repayments), `document.list.confirm`
  (confirm entry).
- **Why:** four of the five routes WRITE to the ledger and were reachable with no
  token at all. Faithful to the reference, whose entire admin route file is
  unauthenticated, but contrary to confirmed decision D1.
- **Reference:** `henza_server/routes/admin.php:12,272` (the `auth:api` wrapper is
  commented out at both ends)
- **Target:** `apps/api/src/modules/accounting/accounting.controller.ts`
- **Breakage check:** `api.getBalance()` is the only app-side consumer and it has
  **zero call sites** in either user app (dead code, already logged as DEAD-01/02).

### 2. Order status change is admin-only (SEC-10)

- **What:** moved `@Public()` from the class to the two customer-facing handlers,
  leaving `PATCH orders/:id/status` behind `order.list.sts.submit`.
- **Why:** it let an anonymous caller move any order's status **and** attribute
  the change to any admin through the DTO's `actorAdminUserId`.
- **Reference:** an admin operation; the admin panel posts to `admin/orders/status`
  (`apps/admin-panel/src/api/endpoints.ts:42,48`), so this route had no caller.
- **Target:** `apps/api/src/modules/orders/orders.controller.ts`
- **Still public:** `POST /orders` and `GET /orders/:id`, because the target has
  no customer session yet — closed in stage 2.

### 3. `GET /customers` no longer leaks the customer book (SEC-08)

- **What:** added `LOGIN_LOOKUP_SELECT` (`id`, `mobile`, `isActive`,
  `isArchived`) and pointed `list()` at it. Removed `fullName`, `nationalCode`,
  `goldDebtGrams`, `fiatDebtRial`, `goldCreditLimitGrams`, `verificationStep`,
  `cityId`, `referredByAgentId`, `nationalIdImageUrl`, `businessLicenseUrl`,
  `shopImageUrl`, `createdAt`, `updatedAt` from that response.
- **Why:** the route is unauthenticated because both apps match the phone number
  in the browser, so it shipped every customer's national ID number, debts,
  credit limit and identity-document URLs to any visitor.
- **Reference:** login was `POST userAuth` → SMS → `POST userVerfiy`, returning
  exactly one customer after the code matched
  (`henza_server/app/Http/Controllers/Api/ApiMobileController.php:39-78`).
- **Target:** `apps/api/src/modules/customers/customers.service.ts`,
  plus `CustomerSummary` narrowed in **both** apps' `src/api/client.ts`
  (parity rule: the same logic change in both).
- **Route survives** until stage 2 replaces the client-side phone match with OTP.

### 4. Test script

- **What:** added `apps/api/scripts/auth-smoke.sh` — asserts 401 without a token,
  403 with a low-privilege token, and pass-through for a super admin, on every
  closed route; plus that the public routes still answer 200 and that
  `GET /customers` exposes only the four login fields.
- **Result:** **23 passed, 0 failed** against a live server and the dev seed.

### Not changed

`/uploads` — per ruling T2, uploaded files including identity documents stay
public. The filename check requested alongside it passed with no changes needed
(md5 of time + name + UUID; no directory listing).

---

## 2026-09-22 — Security hotfix, stage 2 — real customer sessions

Branch `parity/security-hotfix`. Authorised by D6, D7, T1 and T3.

Stage 1 narrowed `GET /customers` but, as the user pointed out, did not close
the leak: the response still carried every customer **id**, and
`/customers/:id`, `/:id/orders` and `/:id/ledger-entries` were still public — so
two requests still reconstructed the whole book. Stage 2 removes the id-bearing
surface entirely.

### 1. Customer JWT, separate from the admin one (T1)

- **New:** `src/modules/customer-auth/` — `CustomerJwtStrategy` (passport
  strategy `'customer-jwt'`), `CustomerJwtGuard`, `@CustomerAuth()`,
  `@CurrentCustomer()`.
- Signed with **`JWT_CUSTOMER_SECRET`**, separate from `JWT_SECRET`, and every
  token carries **`typ: 'customer'`** which the strategy verifies. Either check
  alone would be enough; both are present deliberately.
- Customer state is re-read from the DB on every request, so deactivating or
  archiving a customer takes effect at once rather than at token expiry.
- **Reference:** the same split existed there — `auth:api` for admins,
  `auth('api-customer')` for the app.

### 2. Real OTP (D6)

- **New table `CustomerOtp`** (migration `20260922000000_customer_otp`,
  additive: one new table, nothing existing touched).
- `POST /api/customer/auth/request-otp` ← `ApiMobileController::userAuth` (:39-49)
- `POST /api/customer/auth/verify-otp` ← `ApiMobileController::userVerfiy` (:51-64)
- **Parity behaviour:** the 4-digit `rand(1000,9999)` range, the
  active-customer filter, `Utility::faTOen()` digit normalisation on both the
  number and the code, and rejection on mismatch.
- **Deliberate improvements over the reference** (user-approved, recorded in
  DECISIONS.md so the matrix does not flag them later):
  - the code is stored as a **bcrypt hash**, never plain text;
  - it **expires** after 2 minutes (the reference's never did);
  - **5 attempts** per challenge, then lockout (the reference had no limit);
  - **single use** — a consumed code cannot be replayed;
  - **send throttle**: 60s cooldown per number, 5 per number and 20 per IP per
    10 minutes, counted off the table so it survives restarts;
  - **no enumeration** — an unregistered number returns the same `{sent:true}`.
    The reference's `firstOrFail()` leaked a 404 for unknown numbers.
- No SMS gateway exists in this project (STUB-02), so the code is logged in
  non-production only and the message is persisted as an `SmsMessage` row. The
  reference's message text is kept verbatim for when a gateway lands.

### 3. The id-bearing customer routes are gone

- **Deleted** `customers.controller.ts` — with it `GET /customers`,
  `/customers/:id`, `/:id/orders`, `/:id/ledger-entries`.
- **Replaced by** `/api/customer/me`, `/me/orders`, `/me/ledger-entries`, which
  take the id **from the token**. There is no longer any route that accepts a
  customer id, so the IDOR is closed structurally rather than by a check.
- `CustomersService` stays and is reached only through those routes.
- The admin panel was unaffected — it uses `admin/customers-omde/*`.

### 4. Both apps migrated together (parity rule)

- `stores/session.ts`: `token` is now the credential and `isLoggedIn` is
  token-based. `customerId` is kept for display only and is no longer an
  identity claim.
- `api/client.ts`: sends `Authorization: Bearer`, throws `UnauthorizedError` on
  401 and calls the handler registered in `main.ts`, which clears the session
  and routes to login so stale personal data cannot stay on screen.
- `LoginView.vue`: real two-step OTP. Each app keeps its own markup and styling;
  only the logic changed, and it is identical in both.
- The four account screens now call `getMe()` / `getMyOrders()` /
  `getMyLedgerEntries()`; router guards test `isLoggedIn`.

### Tests

- `apps/api/scripts/auth-smoke.sh` extended with the stage-2 assertions:
  **46 passed, 0 failed** against a live server — old routes 404, customer
  routes 401 without a token, wrong/reused code 401, correct code 200, throttle
  429, no enumeration, customer token rejected on admin routes and admin token
  rejected on customer routes, no id-bearing surface, and `/customer/me`
  returning the token's own customer.
- **jest installed** (dev-only, user-approved) with `jest.config.cjs`, so
  `pnpm test` works for the first time: **7 passed** covering `faToEn`.
  `faToEn` moved to its own `digits.ts` so it can be tested without booting Nest.
- Typecheck clean on api, user-app and user-app-v2; both apps build.

---

## 2026-09-22 — Security hotfix, stage 3 — SEC-02 (orders) + OTP audit

Branch `parity/security-hotfix`. The user declined to defer SEC-02 to Phase 2:
a public `POST /orders` taking `customerId` from the body let anyone place an
order on any customer's account, and an order lands on that customer's **gold
debt and ledger**. That is a money hole, so it is closed here.

### 1. `POST /orders` is customer-authenticated

- **What:** the route is behind `@CustomerAuth()`. `OrdersService.createOrder`
  now takes `customerId` as a **separate argument**, supplied by the controller
  from the token. The body's `customerId` is ignored entirely; a mismatch is
  logged (`OrdersService` warn) and the token always wins.
- `CreateOrderDto.customerId` and the shared `CreateOrderDto` are **optional**,
  so both apps keep validating while they still send it. Removed in Phase 2.
- **Reference:** `ApiMobileController::setOrder` read `auth()->id()`
  (henza_server:533) behind the `api-customer` guard — this restores that.
- **Admin path unaffected:** `AdminOrdersService` places orders *for* a selected
  customer and passes that id explicitly; its route is admin-guarded.

### 2. `GET /orders/:id` is scoped to the owner

- `getOwnedById(orderId, customerId)` matches on both, and a miss is **404, not
  403** — a 403 would confirm the id exists, the same enumeration leak the old
  `/customers/:id` routes had. A nonexistent id and someone else's id are
  indistinguishable.
- Operators use the new `GET /orders/admin/:id` behind rid `order.list`.
  Declared **before** `:id` because Nest matches in declaration order.

### 3. Both apps

- `CartView.vue` in **both** apps now gates on `session.isLoggedIn` (the token)
  rather than on a remembered `customerId`, which is no longer a credential.

### 4. OTP audit (user request 3)

- **No master code, no bypass, no hardcoded code** anywhere in the API or either
  app — verified by grep for `master.?code|bypass|backdoor|1111|0000|1234|skipOtp|DEV_OTP|TEST_OTP`.
  Exactly one code path issues a token, and only after `bcrypt.compare`.
- **SMS provider: none.** No gateway is wired up (STUB-02). In development the
  code is logged once via `Logger`, guarded by `NODE_ENV !== 'production'`.
- **Fixed while auditing:** `deliver()` persisted the real message text — with
  the code in it — into `SmsMessage.body`, which the admin SMS grid both lists
  and full-text searches (`admin-misc.service.ts:135-136`). Any operator with
  the `sms` rid could read live OTP codes, defeating the point of hashing
  `codeHash`. The persisted row is now a redacted audit line; the real text is
  built for the future gateway and not stored. The 9 test rows created during
  this session were deleted.

### Tests

`apps/api/scripts/auth-smoke.sh` extended again — **53 passed, 0 failed**:
order routes 401 without a token, a spoofed body `customerId` ignored in favour
of the token, own order readable, unknown/foreign order id 404, and the admin
order route rejecting a customer token while admitting an admin one.
Typecheck clean on api, user-app, user-app-v2 and shared-types.

## 2026-09-22 — migrate resolve, D13 scope, and the D0/percent migration set

### Standing rule adopted (owner, 2026-09-22)

1. **Migrations run only through the standard Prisma workflow** — `migrate dev`
   in development. **`prisma db execute` is no longer used to apply schema
   changes.** (It was used once, in the security hotfix, to create the
   `CustomerOtp` table; that is what the resolve below repairs.)
2. **Every data deletion is recorded here** — including throwaway rows this
   session creates itself.

### Data deletions (rule 2, applied retroactively to this session)

| When | What | How many | Why |
|---|---|---|---|
| Security hotfix stage 3 | `SmsMessage` rows written by the OTP flow during testing, whose `body` still held the live code before the SEC-11 fix | 9 | They contained real OTP codes in a grid any `sms`-rid operator can read. Test data only; no customer-facing message was ever sent (no gateway is wired). |

No other data has been deleted in this project.

### Ledger repair — approved and executed

```
npx prisma migrate resolve --applied 20260922000000_customer_otp
→ Migration 20260922000000_customer_otp marked as applied.
npx prisma migrate status
→ 9 migrations found. Database schema is up to date!
```

The `CustomerOtp` table already existed (created with `db execute` in stage 2);
this wrote the missing `_prisma_migrations` row **without running any SQL**, so
`migrate deploy` will no longer try to re-create the table. No schema change.

### Documentation

- **D13 recorded** — the retail storefront (wallet, cashback,
  `ConfigStatic['percent']`) is preserved but out of scope. `DECISIONS.md` §D13,
  `PROTECTED.md` §H, and status `⏸️` plus RULE C1 added to the audit skill.
- **Endpoint count corrected: 412, not 369.** `routes/admin.php` has 151 live
  explicit routes, not the 117 the Phase 0 inventory recorded (DOC-01). Of the
  412, **109 are retail storefront**, 15 are `web.php` dev/ops, and **288 stay
  in scope** (218 admin + 70 B2B app).
- **SMS provider report** — the reference uses the Trez panel
  (`smspanel.trez.ir`, `Sms.php:69,97`) with **credentials committed to git**
  (SEC-12, must be rotated). All 12 message templates catalogued, env var names
  proposed. **Nothing implemented; awaiting approval.**
- **MON-08 answered** — `henza_pwa` **computes** `percent_pay`, `discount` and
  `rial_pay`; the user types none of them (`cart.vue:170-179`,
  `Mixins/product/index.ts:69-75`). So Phase 2 item #1 is to derive them
  server-side and ignore the client's values, with a comparison test proving the
  total is unchanged for an ordinary customer. `rash_weight` stays read from the
  DB, recorded as a deliberate deviation.

### New, not yet applied — awaiting approval

| File | Purpose |
|---|---|
| `prisma/migrations/20260922120000_customer_name_parts/migration.sql` | D0 — adds `firstName`/`lastName`, backfills first-token/rest, adds a `customer_sync_full_name` trigger keeping `fullName` in sync in both directions, indexes both parts. Additive; nothing dropped. |
| `prisma/migrations/20260922120100_customer_making_charge_offset/migration.sql` | D9 — adds `makingChargeOffsetPercent DECIMAL(6,3) NOT NULL DEFAULT 0`. |
| `scripts/report-name-split.cjs` | Read-only review report for names with more than two tokens (D0 requirement 3), with `--csv` output. |

### Added and already passing

| File | Purpose |
|---|---|
| `src/modules/pricing/variant-price.ts` | The reference price formula ported verbatim from `ProductVariant.php:183-190`, with the customer offset as an explicit input defaulting to 0. |
| `src/modules/pricing/variant-price.spec.ts` | 11 tests against **hand calculations** derived from the PHP source, covering with/without the offset, the VAT-on-non-metal-portion-only rule, floor-to-1000, and the equivalence between the app folding the offset into `percent_pay` and the server deriving it. |

`npx jest` → **18 passed** (7 existing + 11 new), 2 suites.

---

## 2026-09-22 (later) — D0 + percent applied, SMS provider implemented

### Migrations applied

`migrate dev` could not run (interactive-only, and this shell is not a TTY).
Drift was checked read-only first: the only difference is the pre-existing
`_goldbank_migrations` table, which Prisma would DROP — **it was not dropped**
(DEAD-07). Applied with `migrate deploy`, which touches only the pending files:

```
Applying migration `20260922120000_customer_name_parts`
Applying migration `20260922120100_customer_making_charge_offset`
All migrations have been successfully applied.
→ 11 migrations found. Database schema is up to date!
```

Backfill result (`node scripts/report-name-split.cjs`): 8 customers, 7 split
reliably, 0 single-token, 0 empty, **1 needs review** — `customer-dev-test`
(«کاربر تست توسعه»), a row this session created itself.

### Data deletions (standing rule 2)

| When | What | How many | Why |
|---|---|---|---|
| Round-trip test | `Customer` rows created by the test: 2 successful + 1 whose Persian text the Windows shell had mangled into `?` | 3 | Test fixtures. Customer count back to its original 8. |
| Trigger test | 1 temporary `Customer` row per run, deleted by the script itself and reported on stdout | 1/run | Test fixture. |

### API

- `toRow()` returns the **real** `fname`/`lname` (D0) and `percent` now reads
  `makingChargeOffsetPercent` **from the customer** instead of the referring
  agent's commission rate (D9 / CUST-02).
- `create()` stores the name parts, and **requires `percent`** with the
  reference's own message, `وارد کردن percent الزامی است` — Laravel's stock
  `required` text (`resources/lang/fa/validation.php:99`) with no attribute
  translation for `percent`, so it is verbatim.
- `update()` writes the parts (letting the trigger rebuild `fullName`) and
  **persists `percent`**, which it previously ignored entirely.
- `updateCredit()` accepted `percent` in its signature and never wrote it —
  fixed.
- Sort/filter aliases `fname`/`lname` pointed at `fullName`; they now point at
  the real columns, and `percent` is aliased too. Grid search covers both parts.
- `createSingle()` (retail form, D13) stores the parts too. No storefront
  behaviour changed — only the shared columns are kept consistent.

### SMS — implemented (owner-approved)

- New `SmsModule` / `SmsService` (`@Global`), a port of `Sms.php:57-82`: POST,
  form-urlencoded, 20s timeout, `PhoneNumber`/`Username`/`Password`/`Mobile`/
  `Message`, body trimmed, every message persisted as `Sms::set()` did.
- **Failure handling matches the reference**: `send()` never throws. The
  reference discarded `Sms::Send`'s result, so a gateway outage never aborted
  the order, the document approval or the customer creation that triggered it.
  Failures are logged and returned in `SmsSendResult`.
- **OTP text is byte-identical** to `ApiMobileController.php:47`, including the
  `<#> code is …` first line and the trailing `aMo6iFyUQaY` — the Android SMS
  Retriever hash. A unit test asserts the exact string.
- `assertSmsConfigured()` runs in `main.ts` **before the server listens**: in
  production a missing key throws, naming it; outside production it warns and
  codes are logged locally, so today's dev flow is unchanged.
- Credentials come from the environment only. `.env.example` lists the six names
  with **empty values**; `.env` is gitignored (verified).
- The 12 B2B message templates are implemented per flow in their own phase —
  admin in Phase 1, app in Phase 2 — not pre-emptively.

### Admin panel

- `singleCustomer.vue` — the `split(' ')` fallback is **removed** (D0 item 6).
- `bulkCustomer.vue` — `percent` defaults to **3** on create and is required
  with the legacy message; the edit path coerces the Decimal string to a number
  so diff-send does not re-send an unchanged field; `name` is only sent when a
  name part actually changed, so the whole name is no longer re-submitted on
  every save.
- `ReagentCustomer.vue` — **unchanged**. Its «درصد کمیسیون» is
  `AdminUser.wagePercent`, a genuinely different field from `customers.percent`.

### Tests

- `npx jest` — **32 passed** (7 existing + 11 price formula + 14 SMS config/template).
- `scripts/test-name-trigger.cjs` — **9 assertions**, all three sync directions.
- `scripts/auth-smoke.sh` — **53 passed, 0 failed**.
- **Round-trip test (D12 rule E0)** on the customer entity, live:
  create «محمد علی» + «احمدی» + percent 3 → edit form shows each field
  separately and correctly → no-op save leaves the row **byte-identical** →
  changing only `lname` changes `lastName` and `fullName` (trigger) and nothing
  else → changing only `percent` changes exactly that column. The two-token
  first name «محمد علی» survives intact, which is the defect the owner
  originally reported.
- Typecheck: api ✅ · admin-panel ✅.

---

## 2026-09-22 (later still) — D16 priority change, SEC-02 re-verified

### PRICE-01 stopped (D16)

Price display is retail-storefront work, so it falls under D13 and is now ⏸️.

- `apps/api/src/modules/pricing/variant-price.ts` and its 11 tests are **kept**
  and still run; they are simply not used.
- **Nothing needed reverting.** `computeVariantPrice` was never called from
  anywhere outside its own file and spec — verified by grep over `apps/api/src`
  and `apps/admin-panel/src`. No code had been wired to display a price.
- Making-charge work (`percentage_pay`, `makingChargeOffsetPercent`, wage display
  on variants and order lines) **stays in scope**.
- `ISSUES.md` PRICE-01 re-marked ⏸️ rather than deleted, so the evidence survives.

### SEC-02 re-verified live

Re-tested end to end rather than quoting the earlier run:

| Check | Result |
|---|---|
| `POST /orders` with no token | 401 |
| Body `customerId: "customer-2"` + `customer-dev-test` token | landed on **customer-dev-test**; warn-logged |
| `GET /orders/:id` own | 200 |
| `GET /orders/:id` another customer's | **404** (not 403) |
| `GET /orders/:id` unknown | 404, identical |
| `GET /orders/admin/:id` with a customer token | 401 |

**9/9 passed**, plus **32/32** in `auth-smoke.sh`.

### Data deletions (standing rule 2)

| What | How many | Why |
|---|---|---|
| 1 `Order` created by the SEC-02 test, with its `OrderItem`, `OrderStatusEvent` and `LedgerEntry` rows | 1 order + its children | Test fixture, removed by the test itself. |

### A testing note worth keeping

The dev OTP line briefly appeared to be missing after the SMS change. It was not
a regression: a **stale API process from an earlier test still held port 3077**,
so the new instance died with `EADDRINUSE` and the log being tailed belonged to
the old process. Kill the listener (`netstat -ano | grep :3077`) before
concluding anything from a log. `smsConfigured()` returns false with no
credentials, so the dev log fires exactly as intended — confirmed once the port
was free.

## 2026-09-22 (evening) — D17: SalesExpertProfile + AdminUser name parts

### Migration `20260922180000_sales_expert_profile_and_admin_name_parts`

Shown, dry-run and approved before running. Applied with `migrate deploy`
(D14); drift afterwards is **zero**.

- **`SalesExpertProfile`** — `adminUserId` (unique FK, cascade), `cityId`
  (FK → City, SET NULL), `gramLevel`, `phone`, `nationalCode`.
- **`AdminUser.firstName` / `lastName`** — additive, backfilled first-token/rest,
  with the `admin_user_sync_full_name` trigger (**parts win** when both change).
  Applies to **all** admins, closing D0 requirement 7.
- **Profile backfill** — `INSERT … WHERE NOT EXISTS` gave all 3 existing sales
  experts a profile; the id is derived from the admin id, so a replay cannot
  duplicate.

Owner's two corrections, both applied:

1. **Profiles for existing experts** + an `upsert` in the service on create and
   on a role change to `SALES_EXPERT`, and `listReagents` **left-joins** so an
   expert without a profile still lists (verified by test).
2. **`gramLevel` type matched** to `Customer.goldCreditLimitGrams` —
   `DECIMAL(14,4)`, asserted identical in the dry-run.

**Validation research (as instructed).** The reference is deliberately lax:
`ncode` is `string(20)` nullable and **NOT unique**
(`2020_10_01_120430_customers_table.php:22`), `phone` is `string(15)` nullable
(`2020_10_25_155247_customers_cols.php:17`). Neither has a server rule —
`createCustomer` validates only `mobile` (required|unique) and `percent`
(required) (`AdminController.php:354`) — and both are `required: false` on the
client (`ReagentCustomer.vue:31,95`). Copied exactly; **no uniqueness invented**,
since that would reject data the reference accepts.

### Dry-run before applying

Ran the whole file inside a transaction, **twice**, then rolled back: 14
statements, table created, 3 profiles inserted, backfill correct, replay
produced no duplicates, and the rollback left the database untouched (verified
by re-querying `information_schema`).

### API

- `listReagents` returns **real** `city_id`, `city`, `gram_level`, `phone`,
  `ncode`; the grid's «شهر» and «سطح اعتبار» filters map through the relation.
  `remain` / `rial_remain` stay null — a sales expert is an AdminUser and has no
  ledger of its own (D10).
- `findOne` includes the profile so the edit form populates.
- `create` stores name parts and creates the profile for a sales expert;
  `update` writes the parts and upserts the profile.
- **Every remaining `fname: fullName, lname: ''` was fixed** — 6 more sites in
  `admin-users`, `admin-comments`, `admin-documents` (×2), `admin-orders`,
  `admin-preorders`.

### Admin panel

`ReagentCustomer.vue` gains «شهر», «سقف اعتبار», «کد ملی», «تلفن», and the
**city → commission autofill** ported verbatim from
`henza_admin/src/views/apps/customer/ReagentCustomer.vue:215-228` — including
the reference's falsy test, so a city percent of 0 also falls through to
`cities/get-percent-aux/{id}` (replicated, not "fixed" — D4). `name` is now sent
only when a name part changed, so diff-send is not defeated.

### Tests

| Suite | Result |
|---|---|
| `scripts/test-sales-expert-roundtrip.cjs` (new) | **33/33** |
| `npx jest` | 32/32 |
| `scripts/auth-smoke.sh` | 53/53 |
| `scripts/test-name-trigger.cjs` | 9/9 |
| Typecheck | api ✅ · admin-panel ✅ |

The round trip covers create-with-every-field → edit form populated separately →
byte-identical no-op save → single-field edits, with **«محمد علی» + «احمدی»**
surviving intact, plus both grid filters (positive **and** negative), the
left-join case, and the referrer dropdown.

**A test bug worth recording:** the filter assertions first failed because the
test sent `op: 'eq'`. The grid actually sends `op: '='`
(`XTable.vue:197-200`), and `toCondition` returns null for an unknown operator,
so the filter was silently dropped and the "returns ONLY matches" assertions
passed vacuously against an empty list. The product was correct; the test was
not. **A filter test needs a negative case, or a dropped filter looks like a
pass.**

### Data deletions (standing rule 2)

| What | How many | Why |
|---|---|---|
| `AdminUser` rows created by the round-trip test (one full expert, one profile-less) + their `SalesExpertProfile` rows | 2 per run | Test fixtures, removed by the test itself. |
| 1 temporary `Customer` row per `test-name-trigger.cjs` run | 1 per run | Test fixture. |
