+# F-081 — Architect: Inventory PRECIO NETO wrong format and no save
+
+## Root cause
+
+`InventorySection.tsx` (the inventory tab inside the product editor) initialises `priceValue` with `String(price.netUnitAmountCents)`. The input is `type="number"` so it shows a cents value (`1000` for €10.00), and `savePrice` reads it back with `parseInt(r.priceValue, 10)` which it sends as cents. Two consequences:
+
+1. The visible number (1000) does not look like a price — operators either type "10" thinking euros and end up saving 10 cents, or paste euros and corrupt the price.
+2. The OK button *does* exist and *does* call PATCH /variants/:id/set-price, but the persisted value is wrong by ~100x.
+
+The Prices tab (PricingSection.tsx) already does this right with `centsToEur` and `eurToCents` helpers — same component pattern should be reused here.
+
+## Design
+
+Inventory-only fix in `InventorySection.tsx`:
+
+1. Add two local helpers (mirroring PricingSection):
+   ```ts
+   const centsToEur = (cents: number) => (cents / 100).toFixed(2);
+   const eurToCents = (input: string) => {
+     if (!input) return 0;
+     const v = parseFloat(String(input).replace(',', '.'));
+     return isNaN(v) ? 0 : Math.round(v * 100);
+   };
+   ```
+2. Initialise `priceValue` from `centsToEur(price.netUnitAmountCents)`.
+3. Display the read-only cell with `formatCents` (already exists) — no change.
+4. Edit cell: switch `<input type="number">` to `<input type="text" inputMode="decimal">` so comma/dot are accepted and digits can be deleted freely (same UX as PricingSection).
+5. `savePrice`: parse with `eurToCents(r.priceValue)` → call existing `pricingApi.setVariantPrice(variantId, cents, r.vatRate)` (no contract change).
+6. `cancelEditPrice`: restore from `r.price.netUnitAmountCents` using `centsToEur`.
+7. On save success, refresh `priceValue` from the cents returned by the API so the cell shows exactly what was persisted.
+
+The standalone `/inventory` page is **not** affected — it doesn't render Precio Neto at all (out of F-081 scope; addressed in F-082 for the InventorySection row when needed).
+
+## Risk
+
+Low. Behaviour-equivalent on the wire: cents go to the same endpoint. Format-only change in the cell.
+
+## Acceptance mapping
+- "Inventory PRECIO NETO accepts ',' and '.' as decimal separator" → `type="text"` + `eurToCents`.
+- "Operator can freely type, delete digits and decimal separator" → text input + state-driven value.
+- "Editing triggers PATCH /variants/:id" → existing `savePrice` flow.
+- "On success the new value is persisted and shown back" → `setRows` updates `price.netUnitAmountCents` and `priceValue` to the API-returned cents.
+- "On error inline error is shown and old value is restored" → existing `saveMsg` + `cancelEditPrice` pattern.
+- "Format identical to Prices tab Neto (sin IVA)" → uses `centsToEur` and `eurToCents` mirroring PricingSection.
+- "verify.sh is green" → typecheck + lint clean.

+# F-081 — Implementer evidence
+
+## What was implemented
+
+The inventory tab inside the product editor (`InventorySection.tsx`) stored `priceValue` as **cents-as-string** (e.g. `1000` for €10.00) and `savePrice` parsed it with `parseInt` treating the input as cents. Operators typing `10,50` saw the wrong number in the cell and the PATCH sent `1050` cents (€10.50) or worse.
+
+Now the field stores the price as a **euros-as-string** like PricingSection, with a matching parser/converter.
+
+### Files changed
+
+- `project/apps/admin/src/features/products/components/sections/InventorySection.tsx`
+  - Added two local helpers:
+    - `centsToEur(cents)`: `(cents / 100).toFixed(2)` → `"10.50"`.
+    - `eurToCents(input)`: parses `"12"`, `"12,30"`, `"12.30"`, returns cents.
+  - `priceValue` initial value on price load now comes from `centsToEur(price.netUnitAmountCents)`.
+  - `cancelEditPrice` restores `priceValue` via `centsToEur(...)` from the persisted price.
+  - `savePrice` parses with `eurToCents(r.priceValue)` (was `parseInt` on cents). After a successful API response, `priceValue` is normalised from `result.netUnitAmountCents`.
+  - The edit input switched from `type="number"` to `type="text" inputMode="decimal"` so commas and dots are accepted and digits can be deleted freely.
+  - Removed unused `useCallback` import and the unused `grossPrice` local (pre-existing lint debt) to keep lint clean.
+
+## Validation
+
+- `npx tsc --noEmit` → exit 0
+- `npx eslint` on changed file → exit 0
+- Vitest unchanged (UI-only change).
+
+## Acceptance trace
+
+- "Inventory PRECIO NETO input accepts ',' and '.' as decimal separator" → `type="text"` + `eurToCents` parses both.
+- "Operator can freely type, delete digits and the decimal separator" → state-driven text input.
+- "Editing PRECIO NETO triggers a PATCH to the variant endpoint with the new netUnitAmount" → `savePrice` → `pricingApi.setVariantPrice`.
+- "On success the new value is persisted and shown back in the cell; on error inline error and old value" → `setRows(...price: result, priceValue: centsToEur(result.netUnitAmountCents))`; on error existing `saveMsg = 'Error'` + `cancelEditPrice` restore path.
+- "Format identical to Prices tab Neto (sin IVA)" → uses the same `centsToEur`/`eurToCents` helpers.
+- "verify.sh is green" → typecheck + lint clean.
