 The three PO forms (`new-po-form`, `edit-po-form`, `manager-edit-po-form`) render a shared `<DeliveryLocationField>` — a native `<select name="placeOfDelivery">` populated from the **active** locations, each formatted by `lib/delivery-location.ts` `formatDeliveryLocation(company, address)` → `"Company — address"`. **`PurchaseOrder.placeOfDelivery` stays a free-text snapshot** (no FK): the dropdown only changes how the value is picked, so the export, import, and historical/imported POs are unchanged. On edit, a current value not in the active list is preserved as a leading "(current)" option so it's never silently dropped. Deleting a location is therefore always safe (no PO references it).
 
+### Terms & Conditions catalogue (issue #11)
+
+Same admin-list-feeds-PO-dropdown pattern as Delivery Locations. `TermsCondition` (`category: TermsCategory` enum + `text` + `isActive`) is an admin-managed clause library, managed at `/admin/terms` (gated by **`manage_terms`** — Manager + SuperUser + Admin; CRUD mirrors `/admin/delivery-locations`). The migration **seeds** the prior `TC_DEFAULTS` wording as the starting clauses. The five **named** PO T&C slots (Delivery / Dispatch / Inspection / Transit Insurance / Payment Terms — the `tc*` columns, mapped via `lib/terms.ts` `TC_FIELD_CATEGORY`) become a shared `<TermsField>` **combobox** (native `<input list>` + `<datalist>`) — type a one-off clause or pick a catalogued one — suggesting the active clauses of that category (`lib/terms-data.ts` `getActiveTermsByCategory`). **"Others" stays free text**, and the fixed boilerplate lines (`TC_FIXED_LINE` / `TC_FIXED_LINE_2`) are not catalogued. The `tc*` columns stay **free-text snapshots** (export/import unchanged); since the slot is a free-text combobox, any current/custom value is preserved as-is. No "work order" type — POs only (per the issue's steer).
+
 ### PO Numbering (`lib/po-number.ts`)
 
 Structured format: **`COMPANY/VESSEL/PO_ID/FY`** — e.g. `PMS/HNR1/9000/2024-25`. The financial year is Indian (Apr–Mar) rendered `YYYY-YY`. System-generated `PO_ID` starts at **9000** to avoid clashing with historical numbers. **Imported POs keep their original PO number** verbatim; `parsePoNumber()` extracts the company/vessel/id parts on import.
