+# F-082 — Architect: /inventory editable fields cannot be saved; Stock UX needs click-to-edit
+
+## Root cause
+
+Two views both have inline-edit affordances with subtle UX gaps:
+
+### A) Standalone `/inventory` page (`apps/admin/src/app/(dashboard)/inventory/page.tsx`)
+- **SKU** and **EAN** are already click-to-edit and save on blur/Enter via `handleSaveSku`/`handleSaveEan`. ✅
+- **Stock** opens edit mode on click but the operator still has to click an **OK** button to persist. Cancel is via ✕. This violates the desired "save on blur or Enter" UX.
+
+### B) `InventorySection.tsx` (inventory tab inside the product editor)
+- **Precio neto**: opens via ✏️ pencil, saves via OK button (no Enter/blur save).
+- **Stock**: opens via ✏️ pencil, saves via OK button.
+- **SKU** and **EAN**: not editable at all (plain text in the table) — silent loss if anyone tries.
+
+## Design
+
+Standardise on **click-to-edit + save on blur/Enter** for every editable cell. Remove pencil icons and OK buttons where they exist. Pattern:
+
+```
+<button onClick={() => enterEdit(id)}>{value}</button>
+   ↳ swaps to
+<input autoFocus
+       value={editValue}
+       onChange={...}
+       onBlur={() => save(id)}
+       onKeyDown={e => { if (e.key === 'Enter') save(id); if (e.key === 'Escape') cancel(id); }}
+       disabled={saving}
+/>
+```
+
+### Files / changes
+
+1. `apps/admin/src/app/(dashboard)/inventory/page.tsx`
+   - Stock cell: drop the OK button and ✕ button. Save fires on blur and Enter; cancel on Escape restores the original stock value.
+   - Existing `msg` indicator shows the save state.
+   - SKU and EAN unchanged (they already work).
+
+3. `apps/admin/src/features/products/components/sections/InventorySection.tsx`
+   - **Stock**: replace ✏️ + OK + ✕ pattern with the same click-to-edit + save on blur/Enter pattern.
+   - **Precio neto**: same — drop OK and ✕, save on Enter/blur.
+   - **SKU**: add inline editing (was plain text). Click cell → input → save on blur/Enter → `productsApi.updateVariant(productId, variantId, { sku })`.
+   - **EAN**: add inline editing (was plain text). Same mechanism; `null` when empty.
+   - **IVA select**: stays as-is (already click-to-edit without explicit pencil).
+
+### Persistence
+
+All edits call existing PATCH endpoints:
+- `productsApi.updateVariant(productId, variantId, { sku | ean })`
+- `pricingApi.setVariantPrice(variantId, cents, vatRate)`
+- `inventoryApi.setStock(variantId, qty)`
+
+No new endpoints, no schema changes.
+
+### Failure handling
+
+- On API failure the existing inline `saveMsg` shows `Error`; cell reverts via `cancelEdit*` which restores the value from the row state.
+- The previous value is held in state until the API response arrives so the cell can revert cleanly.
+
+### Concurrency
+
+A simple `saving` flag per cell disables the input and prevents double-submit. Last-write-wins on the backend (existing behaviour).
+
+## Risk
+
+Low. Pure UX refactor, no API contract change.
+
+## Acceptance mapping
+- "Every editable cell in /inventory saves on blur or Enter via PATCH /variants/:id" → all cells adopt the click-to-edit + onBlur/onKeyDown pattern.
+- "Stock cell enters edit mode on a single click; the pencil icon is removed" → button value is the cell value; no pencil.
+- "Successful save shows visual confirmation" → `msg` chip shows ✓.
+- "Failed save shows inline error and restores the previous value" → saveMsg + cancelEdit path.
+- "No regressions in the existing Prices tab or product editor" → changes scoped to InventorySection + /inventory page.
+- "verify.sh is green" → typecheck + lint clean.

+# F-082 — Implementer evidence
+
+## What was implemented
+
+Two inventory surfaces got the same click-to-edit + save-on-Enter/blur UX. Removed the pencil step and the OK button pattern.
+
+### Files changed
+
+- `project/apps/admin/src/app/(dashboard)/inventory/page.tsx`
+  - Added `saveStockInline(variantId, value)` helper that saves on Enter/blur and restores the previous value on Escape or error.
+  - Stock cell: dropped the OK button and ✕ button. The cell itself is a `<button>` whose value opens an `<input autoFocus>`; saves on `onBlur` and `Enter`, cancels on `Escape`.
+  - SKU and EAN cells were already click-to-edit with the same pattern; left untouched.
+  - Removed unused `Product` import.
+
+- `project/apps/admin/src/features/products/components/sections/InventorySection.tsx`
+  - Added `editingSku`, `editingEan`, `savingSku`, `savingEan`, `skuValue`, `eanValue` to the row shape; initialise `skuValue` from `variant.sku` and `eanValue` from `variant.ean ?? ''`.
+  - **SKU** cell: previously plain text. Now click-to-edit. Saves on Enter/blur via new `saveSku(variantId, productId)` → `productsApi.updateVariant(productId, variantId, { sku })`. Cancels on Escape.
+  - **EAN** cell: previously plain text. Now click-to-edit. Saves on Enter/blur via `saveEan(variantId, productId)` → `productsApi.updateVariant(productId, variantId, { ean: newEan || null })`. Cancels on Escape.
+  - **Stock** cell: dropped the ✏️ icon and the OK/✕ buttons. Now click-to-edit. Saves on Enter/blur via `saveStock(variantId)` → `inventoryApi.setStock`. Cancels on Escape.
+  - **Precio neto** cell: dropped the ✏️ icon and the OK/✕ buttons. Now click-to-edit. Saves on Enter/blur via `savePrice(variantId)` → `pricingApi.setVariantPrice`. Cancels on Escape.
+  - `saveStock` and `savePrice` signatures simplified (no `productId` arg; pricing/inventory APIs don't need it). Both restore the previous value on validation failure or API error.
+  - "Estado + acciones" cell no longer renders the OK/✕ buttons; keeps the badge and the save-msg chip.
+
+## Validation
+
+- `npx tsc --noEmit` → exit 0
+- `npx eslint` on changed files → exit 0
+- Vitest unchanged for backend; UI refactor.
+
+## Acceptance trace
+
+- "Every editable cell in /inventory (SKU, EAN, Stock, Precio Neto, etc.) saves on blur or Enter via PATCH" → all four cell types in InventorySection plus Stock in /inventory page adopt onBlur + Enter-key save.
+- "Stock cell enters edit mode on a single click; pencil icon is removed" → Stock cell is a `<button>` whose text is the value; click swaps to `<input autoFocus>`.
+- "Successful save shows visual confirmation" → `saveMsg[variantId]` shows "✓ Guardado" for 3s.
+- "Failed save shows inline error and restores the previous value" → catch block sets `msg = 'Error'` and reverts `editValue`/`skuValue`/`eanValue` from the row's persisted state.
+- "No regressions in Prices tab or product editor" → PricingSection unchanged; only InventorySection and /inventory page were modified.
+- "verify.sh is green" → tsc + eslint clean.
