# Gishen Admin — Backend Spec Sheet

**Repo:** Gishen-Admin  
**Audience:** Shared backend team (consolidate with Ecom / Mobile / B2B sheets later)  
**Base URL (TBD):** `https://api.gishen.example/v1`  
**Auth:** Bearer JWT for staff roles  
**Mocks:** Admin SPA uses in-memory mocks until `VITE_USE_MOCKS=false` and `VITE_API_BASE_URL` point here.

**Cross-app master:** [`GISHEN-MASTER-SPEC.md`](./GISHEN-MASTER-SPEC.md) — product surface map, shared domain objects, auth matrix, and divergence notes vs Mob / Ecom / B2B. Refresh the master (and this sheet) before pushes; see its Update rule.

**Entity schemas:** [`schemas.md`](./schemas.md) — TypeScript + field tables for Money, Staff, Organisation/Commercial, Doctor, Prescription, Order, Catalogue Item, Stock, Customer, Settlement, Dispatch, envelopes.

## Conventions

| Item | Convention |
| --- | --- |
| Content type | `application/json` (multipart for imports / uploads) |
| IDs | UUID v4 |
| Money | **`Money`:** `{ "amount": "1250.00", "currency": "ETB" }` (decimal string, major units). Admin SPA may also keep numeric major-ETB helpers for UI demos — sync with `commercial` on activate. |
| Errors | `{ "error": { "code": string, "message": string, "details"?: object } }` |
| Pagination | `?page=&limit=` → `{ data, meta: { page, limit, total } }` |

### Entity schemas (setup)

Full **platform** schemas (shared primitives, Admin ops, B2B portal, Ecom/retail, events) live in **[`schemas.md`](./schemas.md)**. Keep that file in sync with Admin mocks/types, B2B `docs/backend/entities/`, and Ecom `docs/backend.md`.

| Area | Schema anchors |
| --- | --- |
| Shared Money / envelopes / events | [§1–2](./schemas.md#1-shared-primitives) |
| Principals (Staff, Doctor, B2B session, Customer) | [§3](./schemas.md#3-principals--actors) |
| Org · Commercial · Branch · Doctor | [§4](./schemas.md#4-admin--organisations--doctors) |
| Rx · Order | [§5](./schemas.md#5-admin--prescriptions--orders) |
| Catalogue · Stock · Procurement | [§6](./schemas.md#6-admin--catalogue-stock--procurement) |
| POS · Loyalty · Marketing · FAQ | [§7](./schemas.md#7-admin--pos-crm-loyalty--marketing) |
| Settlements · Dispatch · Admin imports · Audit | [§8](./schemas.md#8-admin--finance-dispatch-imports--audit) |
| B2B registration · Member · Package · Dept | [§9](./schemas.md#9-b2b-portal-schemas) |
| B2B Finance · tenant Migration · Rx views | [§10](./schemas.md#10-b2b-finance-migration--rx-views) |
| Ecom catalog · order create · entitlement · KYC · payments | [§11](./schemas.md#11-ecom--retail-schemas) |
| Path-prefix ownership map | [§12](./schemas.md#12-backend-ownership--path-prefixes) |

#### Quick reference — Money & Org (canonical)

```ts
interface Money { amount: string; currency: 'ETB' }

type OrgStatus = 'pending_activation' | 'active' | 'suspended' | 'closed' | 'rejected'

interface CommercialTerms {
  credit_limit: Money
  credit_used: Money
  payment_terms_days: number
  price_list_id?: string
  contract_start?: string
  contract_end?: string
  activated_at?: string
  activated_by?: string
}
```

#### Quick reference — Prescription line dosing

```ts
type DosingFrequency = 'QD' | 'BID' | 'TID' | 'QID' | 'QXH' | 'custom'

interface PrescriptionItem {
  name: string
  qty: number
  controlled?: boolean
  frequency?: DosingFrequency
  intervalHours?: number
  times?: string[]   // HH:mm — Mob reminder seed
}
```

## Staff roles

`pharmacist` · `stock_manager` · `procurement` · `finance` · `marketing_manager` · `operations` · `super_admin`

Pharmacist (and optionally stock) sessions include `branchId`.

### External actors (not Admin staff roles)

| Actor | Auth | Affiliation | Can |
| --- | --- | --- | --- |
| **Doctor** | Separate doctor JWT (or shared IdP with `actor=doctor`) — **not** a pharmacy `StaffRole` | Must belong to ≥1 **hospital** or **clinic** organisation | Create prescriptions; create orders (including for **guest** patients without platform accounts) |
| End customer (guest) | None required for admin/doctor-assisted checkout | — | Is the subject of an order/Rx; may later claim/merge into a registered CRM profile |

Doctors **cannot** manage platform catalogue, team RBAC, finance settlements, or other hospitals’ rosters. AuthZ is scoped to their hospital org(s).

---

## Auth & me

Staff Admin authenticates with **Bearer JWT**. Login supports multiple identity providers; all paths mint (or exchange into) the same staff access/refresh pair and `GET /auth/me` principal.

| Method | Path | Roles | Description |
| --- | --- | --- | --- |
| POST | `/auth/staff/login` | — | Email/password → tokens + user |
| POST | `/auth/staff/oauth/google` | — | Exchange Google ID token (GIS / OAuth) → staff tokens + user |
| POST | `/auth/staff/phone/start` | — | `{ phone }` → start OTP (rate-limited); `{ challengeId, expiresIn }` |
| POST | `/auth/staff/phone/verify` | — | `{ challengeId, code }` → tokens + user when phone is linked to a staff account |
| POST | `/auth/staff/telegram` | — | Telegram Login Widget payload (hash-verified) → tokens + user |
| POST | `/auth/refresh` | refresh | Rotate access |
| POST | `/auth/logout` | staff | Revoke |
| GET | `/auth/me` | staff | Current principal, roles, branchId, avatarUrl, `authProvider` |
| PATCH | `/users/me` | staff | `{ preferredLocale?: "en"\|"am", name?, phone?, avatarUrl? }` |
| POST | `/users/me/avatar` | staff | Multipart image upload → `{ avatarUrl }` |

### Auth providers

| Provider | Flow | Staff Admin | Doctor / external |
| --- | --- | --- | --- |
| **Email** | `POST /auth/staff/login` with password (magic-link optional later — not in Admin mock) | Primary for pharmacy staff | Doctor uses `POST /auth/doctor/login` (email/invite); same IdP may be shared later with `actor=doctor` |
| **Google** | Browser Google Identity Services → ID token → `POST /auth/staff/oauth/google` | Allowed when staff email is in Google Workspace / allow-listed domain | TBD for doctors (hospital Google vs separate realm) |
| **Phone (OTP)** | `phone/start` → SMS/WhatsApp OTP → `phone/verify` | Staff accounts with verified `phone` on user profile | Useful for guest order claim / patient flows (out of Admin staff session); doctor phone login TBD |
| **Telegram** | [Telegram Login Widget](https://core.telegram.org/widgets/login) on Admin SPA → server verifies `hash` with bot token → `POST /auth/staff/telegram` | Optional for staff who linked Telegram id; also used for **rider** dispatch identity (see Dispatch) | Not primary for doctor clinical auth |

**Login response sketch:**

```json
{
  "accessToken": "...",
  "refreshToken": "...",
  "user": {
    "id": "uuid",
    "name": "Hana Pharmacist",
    "email": "pharmacist@gishen.et",
    "role": "pharmacist",
    "branchId": "uuid",
    "preferredLocale": "en",
    "avatarUrl": "https://cdn.example/avatars/hana.jpg",
    "authProvider": "email"
  }
}
```

`authProvider` values: `email` | `google` | `phone` | `telegram`.

**Google body sketch:** `{ "idToken": "..." }`  
**Phone start:** `{ "phone": "+251911000000" }`  
**Phone verify:** `{ "challengeId": "uuid", "code": "123456" }`  
**Telegram body:** widget fields (`id`, `first_name`, `username`, `auth_date`, `hash`, …) as returned by the Login Widget.

Mock keys:
- `authStore.login` → `/auth/staff/login`
- `authStore.loginWithProvider('google'|'phone'|'telegram')` → oauth / phone verify / telegram (Admin SPA mock signs in as demo pharmacist unless overridden)

UI: `/login` (provider buttons + email form + phone OTP step + Telegram CTA + demo picker), `/profile` (every authenticated role; not permission-gated), topbar “My profile”

Env placeholders:

| Side | Vars |
| --- | --- |
| Client (Admin SPA / `.env.example`) | `VITE_GOOGLE_CLIENT_ID`, `VITE_TELEGRAM_BOT_USERNAME` — empty = mock provider UX |
| Server only (never ship to Vite) | Google token audience / Workspace allow-list; `TELEGRAM_BOT_TOKEN` (Login Widget hash verify); SMS/OTP gateway credentials (AfricasTalking / Twilio / …) |

Typed on client as `ImportMetaEnv` in `src/vite-env.d.ts`.

---

## Orders (branch queue)

| Method | Path | Roles | Description |
| --- | --- | --- | --- |
| GET | `/pharmacy/orders` | pharmacist, operations, super_admin | `?branchId=` required for pharmacist; filters: `status`, `fulfillment`, `channel`, `customerType`, `q` |
| POST | `/pharmacy/orders` | pharmacist, operations, super_admin, **doctor** | Staff- or doctor-created order (call centre / walk-in / clinical). Supports **guest** customers |
| GET | `/pharmacy/orders/:id` | pharmacist, operations, super_admin, doctor (own) | Detail: header + line items + payment + fulfillment + customer type |
| GET | `/pharmacy/orders/:id/timeline` | pharmacist, operations, super_admin | Ordered status/audit events for the detail timeline |
| POST | `/orders/:id/confirm` | pharmacist, super_admin | Confirm stock |
| POST | `/orders/:id/assign-rider` | pharmacist, operations, super_admin | `{ riderId }` |
| PATCH | `/orders/:id/status` | pharmacist, operations, super_admin | Status lifecycle |

### Guest / unauthenticated end-customer orders

The **authenticated** principal is always staff or a doctor. The **end customer** may be unauthenticated:

| Field | Notes |
| --- | --- |
| `customerType` | `registered` \| `guest` (required on create) |
| `customerId` | Required when `registered`; **omit** when `guest` |
| `customerName` | Display name (guest walk-in / phone caller / patient) |
| `customerPhone` | **Required for guests**; recommended for registered (denormalised) |
| `notes` | Optional staff/doctor free text |
| `doctorId` / `orgId` | Optional; set when a Doctor actor initiates the order |

**Limits (proposed):** guest orders must include a valid phone; controlled SKUs still require an approved Rx; no loyalty earn by default for guests unless a later claim/merge attaches the order to a CRM profile. Doctors may place guest orders for patients without accounts, scoped to their hospital.

**Create body sketch:**

```json
{
  "customerType": "guest",
  "customerName": "Walk-in · Aster",
  "customerPhone": "+251911880011",
  "notes": "Caregiver collecting",
  "branchId": "uuid",
  "fulfillment": "pickup",
  "channel": "doctor",
  "doctorId": "uuid",
  "lines": [{ "sku": "PCM-500", "qty": 20 }]
}
```

Detail response adds `items[] { sku, name, qty, unitEtb }`, `timeline[] { at, title, detail, tone }`, resolved `rider`, and optional `doctor` / `organisation`.

Mock: `mocks/data.orders`, `mocks/data.orderLines`, `mocks/data.orderTimeline`  
UI: `/orders/new` (Guest customer vs Registered customer toggle), `/orders/:id`

---

## Prescriptions

| Method | Path | Roles | Description |
| --- | --- | --- | --- |
| GET | `/pharmacy/prescriptions` | pharmacist, super_admin | Branch-scoped queue; filters: `status`, `controlled`, `flagged` (`open`\|`none`), `flagCode`, `q` |
| POST | `/pharmacy/prescriptions` | pharmacist, super_admin, **doctor** | Staff Rx intake or doctor-authored Rx; body includes `doctorId` when attributed; optional `flags[]` seed on create |
| POST | `/admin/prescriptions/:id/verify` | pharmacist, super_admin | `{ status: approved\|queried\|rejected, qtyAdjustments?, substitute?, notes? }` |
| POST | `/pharmacy/prescriptions/:id/dispense` | pharmacist | `{ batch, quantity }` stamped pharmacistId + time |
| GET | `/pharmacy/prescriptions/controlled-report` | pharmacist, super_admin | Controlled-substance report |
| GET | `/pharmacy/prescriptions/:id` | pharmacist, super_admin, doctor (own) | Detail: items (incl. dosing schedule), `flags[]`, controlled line flags, review trail, linked doctor |
| POST | `/pharmacy/prescriptions/:id/flags` | pharmacist, super_admin | Add flag `{ code, severity?, note }` → opens review marker (defaults severity from code) |
| POST | `/pharmacy/prescriptions/:id/flags/:flagId/resolve` | pharmacist, super_admin | `{ resolutionNote }` → `status=resolved`, stamps `resolvedBy` / `resolvedAt` |
| GET | `/pharmacy/refills` | pharmacist, super_admin | Days-of-supply / script expiry oversight |

UI: `/prescriptions` (open-flag count badge + Filters: Flags / Flag type), `/prescriptions/new` (doctor select + per-line dosing + optional initial flag), `/prescriptions/:id` — Approve is the sole primary header action; Reject / Query live in an overflow menu and as an inline footer on the verification section; **Flags** section supports add + resolve with history. Medications table shows interval/frequency and dose times.

### Prescription flags (review markers)

Operational / clinical **review flags** on an Rx header — distinct from line-item `controlled` and workflow `status`. Staff add flags during intake or review; open flags surface on the queue until resolved. Resolved flags remain for audit.

| Field | Type | Notes |
| --- | --- | --- |
| `id` | string | Flag id |
| `code` | enum | `controlled_substance` \| `interaction_concern` \| `incomplete_rx` \| `fraud_suspicion` \| `stock_shortage` \| `needs_clarification` \| `allergy_concern` \| `dosing_concern` \| `other` |
| `severity` | `info` \| `warning` \| `critical` | Defaults from `code` when omitted on create |
| `note` | string | Why this Rx needs attention |
| `createdBy` | string | Staff display name (or id + denorm) |
| `createdAt` | ISO datetime | |
| `status` | `open` \| `resolved` | |
| `resolvedBy?` | string | Set on resolve |
| `resolvedAt?` | ISO datetime | Set on resolve |
| `resolutionNote?` | string | How it was cleared |

Rx list may expose derived helpers: `openFlagCount`, highest open severity (for badge colour).  
Helper (Admin): `src/lib/prescriptionFlags.ts`. Mock seeds: `rx-1001`–`1003`, `rx-1005`, `rx-1008`.

### Prescription medication line items (schedule)

Each `items[]` entry on create / detail carries dosing instructions used by pharmacist counsel and **mobile dose reminders**. Clock `times` use the same shape as mobile `Reminder.times` (`HH:mm` strings, 24h). Backend should persist the pharmacist’s final `times` list (and `intervalHours` for QXH) so the patient app can seed reminders without re-deriving.

| Field | Type | Notes |
| --- | --- | --- |
| `name` | string | Medicine label / strength as entered |
| `qty` | number | Dispense quantity |
| `controlled?` | boolean | Controlled-substance flag |
| `frequency?` | `QD` \| `BID` \| `TID` \| `QID` \| `QXH` \| `custom` | Once / 2× / 3× / 4× daily, every N hours, or custom clock list |
| `intervalHours?` | number | **Required** when `frequency === "QXH"` (hours between doses, ≥ 1) |
| `times?` | string[] | Clock times `HH:mm` (24h), e.g. `["08:00","14:00","20:00"]`. Admin intake requires ≥ 1 time |

**Frequency → default suggested times** (Admin `defaultTimesForFrequency`; pharmacist may add/remove slots):

| Frequency | Default `times` |
| --- | --- |
| `QD` | `08:00` |
| `BID` | `08:00`, `20:00` |
| `TID` | `08:00`, `14:00`, `20:00` |
| `QID` | `08:00`, `12:00`, `16:00`, `20:00` |
| `QXH` | Generated from `intervalHours` starting 08:00 until midnight (default interval 8h if omitted in UI) |
| `custom` | Seed `08:00`; pharmacist edits freely |

**Create body sketch:** `POST /pharmacy/prescriptions` / `POST /doctor/prescriptions`:

```json
{
  "customerName": "Guest patient · no account",
  "branchId": "uuid",
  "doctorId": "uuid",
  "orgId": "uuid",
  "items": [
    {
      "name": "Amoxicillin 500mg",
      "qty": 21,
      "controlled": false,
      "frequency": "TID",
      "times": ["08:00", "14:00", "20:00"]
    },
    {
      "name": "Paracetamol 500mg",
      "qty": 20,
      "frequency": "QXH",
      "intervalHours": 6,
      "times": ["08:00", "14:00", "20:00"]
    }
  ]
}
```

Rx header also stores denormalised `prescriber` (doctor display name). Patient on Admin intake may be a **guest name** (no CRM `customerId` required).

Helper (Admin): `src/lib/dosingSchedule.ts` — `DOSING_FREQUENCY_OPTIONS`, `defaultTimesForFrequency`, `formatFrequencyLabel`, `formatDoseTimes`.

Mock: `mocks/data.prescriptions` · Types: `PrescriptionItem`, `DosingFrequency`  
UI: create sets schedule per line; detail medications table shows frequency label + dose times.

---

## Doctors (hospital-affiliated actors)

Doctors are **not** floating platform users. Onboarding is via a **hospital** or **clinic** organisation (`orgType`). Finance / super_admin manage the roster in Admin; doctors authenticate separately to create clinical artefacts.

| Method | Path | Roles | Description |
| --- | --- | --- | --- |
| GET | `/admin/doctors` | finance, super_admin; pharmacist (read for attribution) | Filters: `orgId`, `status`, `q` |
| POST | `/admin/doctors` | finance, super_admin | Invite/create `{ orgId, name, specialty, licenseNumber, phone, email, branchId?, sendInvite? }` — **rejects** if org is not hospital/clinic |
| GET | `/admin/doctors/:id` | finance, super_admin; pharmacist (read) | Profile + recent Rx/orders |
| PATCH | `/admin/doctors/:id` | finance, super_admin | Update profile / deactivate |
| POST | `/admin/doctors/:id/invite` | finance, super_admin | Provision or re-send linked login |
| GET | `/admin/organisations/:id/doctors` | finance, super_admin | Doctors for one hospital org |
| POST | `/auth/doctor/login` | — | Doctor email/password or invite token → doctor JWT |
| GET | `/doctor/me` | doctor | Principal + hospital memberships |
| POST | `/doctor/prescriptions` | doctor | Create Rx (patient may be guest name-only) |
| POST | `/doctor/orders` | doctor | Create order for registered or **guest** patient; hospital-scoped |

**AuthZ notes**

- Doctor tokens are scoped to their `orgId`(s); cannot read other hospitals’ doctors or orgs  
- Cannot mutate catalogue, stock master, finance, team, or audit  
- Pharmacist verification remains the gate for controlled dispensing  
- Admin UI module: existing `organisations` permission (finance + super_admin)

**Fields:** `id`, `name`, `specialty`, `licenseNumber`, `phone`, `email`, `status` (active\|inactive), `orgId`, `orgName`, `branchId?`, `hasLinkedAccount`, `createdAt`, `updatedAt`, `avatarUrl?`

Mock: `mocks/data.doctors`  
UI: `/doctors`, `/doctors/new?orgId=`, `/doctors/:id`; hospital org detail → Add doctor

---

## Medication items (catalogue)

Master product identity. **Stock rows reference an Item** via `itemId`; batch/lot, manufacture date, expiry, and branch qty live on Stock only. Do not recreate a product on every goods receipt.

| Method | Path | Roles | Description |
| --- | --- | --- | --- |
| GET | `/admin/catalog/items` | stock_manager, pharmacist (read), procurement (read), super_admin | Filters: `productType`, `efdaStatus`, `mergeStatus`, `therapeuticClass`, `q` |
| POST | `/admin/catalog/items` | stock_manager, super_admin | Create item; server assigns immutable internal SKU |
| GET | `/admin/catalog/items/:id` | stock_manager, pharmacist (read), procurement (read), super_admin | Full record + ownership tags + audit |
| PATCH | `/admin/catalog/items/:id` | stock_manager, super_admin | Update (SKU immutable); field-group ownership may reject ERP-owned writes from Platform |
| GET | `/admin/catalog/items/:id/history` | stock_manager, super_admin | Change log |
| POST | `/admin/catalog/items/match` | stock_manager, super_admin | Duplicate assist body `{ genericName, strength, dosageForm, packSize, manufacturer }` → `{ candidates: [{ id, confidence, matchKey }] }` |
| POST | `/admin/catalog/items/:id/merge` | stock_manager, super_admin | `{ candidateId, status: approved\|rejected }` — reversible 30d |
| POST | `/admin/catalog/items/:id/merge/reverse` | stock_manager, super_admin | Undo approved merge within 30 days |
| GET | `/admin/catalog/items/:id/variants` | same read | Pack-size children linked to parent |
| POST | `/admin/catalog/items/:id/variants` | stock_manager, super_admin | Attach pack variant `{ packSize, barcode, sellingPriceEtb }` |
| POST | `/admin/catalog/items/:id/media` | stock_manager, super_admin | Multipart images (min 1); badges blocked for Rx/Controlled |

**Field groups (create/detail):**

1. Core identification — SKU (immutable), generic/INN, brand, manufacturer, country, EFDA number, barcodes[]  
2. Classification — product type (`OTC`\|`Rx`\|`Controlled`\|`Medical device`\|`Beauty`\|`Wellness`), therapeutic class, activeIngredients[], dosage form, route, controlled schedule  
3. Packaging — pack size, `baseUnit` (stock UOM), `sellByUnit`, `packUnit`, **`uoms[]` multi-UOM table**, parent/variant links  
4. Pricing — cost (ERP-owned), selling price (+ owner ERP\|Platform), currency ETB, VAT, promo eligibility (**auto-off for Rx/Controlled**, no override), B2B price-list ref, optional `compareAtPriceEtb`  
5. Regulatory — Rx-required, EFDA status, controlled flag+schedule, advertising-restriction (auto from type), age restriction  
6. Content — short description, dosage guidance, side effects (free text + structured mild/severe), warnings, storage (+ structured `storageNotes[]`), `directions[]`, `pharmacistTip`, `useCase`, similar alternatives[]  
7. Storefront / mobile PDP — fields below; Admin detail shows a live preview shaped for Gishen mobile  
8. Inventory defaults — default reorder point, expiry-alert days (on-hand/reserved/incoming are derived from stock)  
9. Media — images[], thumbnail, merchandising badges (**disabled for Rx/Controlled**), SEO slug/title/description  
10. Dedupe — `matchKey`, confidence, mergeCandidateId, mergeStatus, approver, timestamps  
11. Ownership & audit — per field-group source of truth, last ERP sync + error, created/modified by/at  
12. Relationships — B2B-eligible category tag; loyalty earn/redeem eligibility (**auto-excluded for Rx/Controlled**)

### Multi-UOM (ERPNext-style)

Warehouse quantity is **always** counted in the stock / base UOM (`baseUnit`). Additional purchase/sales units convert via `conversionFactor` = how many **stock units** equal one of that UOM. The stock UOM row always has `conversionFactor: 1`.

| Field | Type | Notes |
| --- | --- | --- |
| `uoms[]` | `ItemUom[]` | Allowed units for the item |
| `uoms[].uom` | string | e.g. `tablet`, `strip`, `box` |
| `uoms[].conversionFactor` | number | Stock qty per 1 of this UOM |
| `uoms[].isStockUom?` | boolean | Exactly one true; matches `baseUnit` |
| `uoms[].isPurchaseUom?` | boolean | Used on PO / receive |
| `uoms[].isSalesUom?` | boolean | Used on sales / POS lines |

**Helpers (Admin mock / shared):** `resolveItemUoms` (falls back to `buildDefaultUoms` from pack labels when `uoms` empty), `toStockQty(qty, fromUom, item)`, `fromStockQty(stockQty, toUom, item)`, `stockUomOf(item)`.

**API expectation:** `POST`/`PATCH` `/admin/catalog/items` accept `uoms`; stock receive / POS / order lines may submit qty in a sales/purchase UOM — server converts with `toStockQty` before decrementing inventory. Reject unknown UOM labels.

Example: `1 strip = 10 tablet` → selling 2 strips deducts `20` stock units.

### Storefront / mobile PDP fields

Aligned with Gishen mobile product detail (`product/[id]`). Admin create/edit captures these; detail page previews via `storefrontPdpPreview(item)`.

| Field | Notes |
| --- | --- |
| `storefrontUnit?` | Shelf / pack label shown as mobile `product.unit` (e.g. `10 capsules/strip`); falls back to `packSize` / `sellByUnit` |
| `useCase?` | Chip above name (e.g. Pain & Fever); falls back to therapeutic class |
| `compareAtPriceEtb?` | Strike-through compare-at price |
| `sideEffectsMild?` / `sideEffectsSevere?` | Structured lists; mild falls back to parsing free-text `sideEffects` |
| `directions?` | `{ title, body }[]` stepper; falls back from `dosageGuidance` + `warnings` |
| `storageNotes?` | `{ title, body }[]` cards; falls back from `storageInstructions` |
| `pharmacistTip?` | Callout; falls back to `warnings` |

Preview mapping also exposes name, brand, slug, sku, price, images, Rx flag, badge, form, generic, drug class, ingredient strengths.

Mock: `mocks/catalog.ts` (`catalogItems`, `itemChangeHistory`, `ItemUom`, …)  
UI: `/items`, `/items/new` (multi-UOM editor + PDP fields), `/items/:id` (UOM table + Storefront / Mobile PDP section)  
Stock create: `POST /pharmacy/inventory` prefers `{ itemId, branchId, batch, … }` over free-typed product fields. UI deep-link `?item=`

**Activate body sketch:**

```json
{
  "commercial": {
    "credit_limit": { "amount": "2000000.00", "currency": "ETB" },
    "payment_terms_days": 30,

```

**Cross-repo:** B2B `POST /v1/org/register` creates `org_status=pending_activation` and emits `org.registration_submitted`. Admin activate emits `org.activated` with commercial payload matching B2B `organisation.md`. (Legacy sketch `POST /company/register` / bare `pending` / `/approve` superseded.)

## Navigation & page directory (frontend convention)

`src/config/navigation.ts` is the **single source of truth** for every navigable
destination in the Admin SPA. It feeds both the sidebar and the Cmd+K / Ctrl+K
command palette in the topbar.

**When you add a page or feature, register it there.** A route added to
`src/app/AppRoutes.tsx` but missing from the registry is unreachable by search;
an entry whose `path` has no matching route produces a broken result.

Each entry carries `id`, `title` (+ optional `labelKey` for i18next),
`description`, `path`, `module` (`ModuleKey`, used for RBAC via `canAccess`),
`icon`, `group` (`NavGroupId`), `keywords` (search synonyms), `kind`
(`page` | `action`) and `showInSidebar`.

`group` is the operational domain — Overview, Daily operations, Inventory &
supply, Finance & accounts, Customers & growth, Administration, Support, plus a
palette-only Actions group. It drives the sidebar section headers *and* the
palette headings from one field, so the two cannot drift. Labels live in
`navGroups`; `sidebarSections(role)` returns the grouped, permission-filtered
sidebar and drops any section whose children the role cannot access.

Palette results are permission-filtered with the same `roleModules` map the
route guards use, so no backend change is needed — but any new module key added
server-side must also exist in `ModuleKey` and `roleModules`.

Current SPA destinations of note: `/pos`, `/items`, `/doctors` (orgs module —
hospital/clinic roster), `/profile` (palette + topbar; not a gated module),
Payment Gateways `/finance/gateways` (palette-only).

Entity detail routes (`orders/:id`, `stock/:sku`, `items/:id`, …) are
deliberately not registered: they require a record id. Register the list page
instead.

**List filters (UI):** toolbars with more than three filters collapse into a
modal with staged Apply/Cancel and removable active chips. Search stays inline.
Backend continues to accept flat query params; no change required.

**Avatars:** staff, customers, and riders expose optional `avatarUrl`. Clients
resolve `avatarUrl` → generated placeholder → initials. Upload: `POST /users/me/avatar`
or admin `POST /admin/users/:id/avatar`.

## Open questions

1. ~~Money units~~ → **Resolved default:** `Money` decimal-string major ETB (B2B). Close Ecom open decision to match.  
2. Driver channel assumption: Telegram bot (flag if SMS/WhatsApp preferred)  
3. Checkout entitlement-split: shared component across Ecom/Mobile/B2B (out of Admin UI)  
4. Amharic dates: Gregorian with Amharic month names (current) vs Ethiopian calendar (`am-ET-u-ca-ethiopic`) — year differs (~2018 E.C. for 2026 G.C.); need product decision  
5. Tickets-app vendor: POS integration is pluggable — confirm production partner API once chosen  
6. Invoice OCR provider for `/pos/invoices/extract` (Admin currently simulates extraction)  
7. Catalogue merge queue ownership: Stock Manager vs dedicated data-steward role  
8. Doctor identity provider: dedicated doctor realm vs B2B portal users with `role=doctor` under hospital orgs  
9. Guest order claim: can a later registered customer attach historical guest orders by phone OTP? Retention / masking of guest PII?  
10. Guest order ceilings: max ETB / controlled-item rules without registered identity — confirm with compliance  
11. Multi-hospital doctors: allow one clinician affiliation to multiple hospital orgs?  
12. Multi-UOM source of truth: Platform-editable vs ERP-synced conversion factors — which field-group ownership wins on conflict?  
13. Mobile reminder sync: push dose `times` on Rx approve vs on first dispense / patient claim?  
14. Google OAuth: production Web client ID + allowed staff email domains / Workspace org for Admin  
15. Telegram Login Widget: production bot username and whether staff must pre-link Telegram id in Admin before first login  
16. OTP provider for staff phone login: AfricasTalking vs Twilio vs local SMS gateway; shared with guest-order claim OTP?  
17. Should doctor login reuse Google / phone / Telegram providers or stay email+invite only?
