+# F-080 — Architect: PVP (IVA incl.) input locks decimal editing
+
+## Root cause
+
+`PricingSection.tsx` binds the PVP `<input>` to `value={grossEur}` where `grossEur` is **recomputed on every render** as `centsToEur(Math.round(netCents * (1 + ratePercent / 100)))`. Every keystroke in PVP fires `onChange` which writes to `net`; the next render immediately rewrites the PVP `value` based on the (new) net. The input shows a value that never matches what the user typed — feels "locked".
+
+Secondary issue: `<input type="number">` ignores locale decimals. Browsers (Chrome/Safari) reject commas outright, and Firefox sometimes snaps to an integer. Sibling Neto input has the same `type="number"` but happens to feel usable because the value displayed in Neto is the actual state (`net[v.id]`), so the user controls the display string directly.
+
+## Design
+
+Treat PVP as a first-class controlled input, exactly like Neto:
+
+1. Add a `gross` state alongside `net`: `Record<string, string>` holding the PVP value per variant (euros as a user-typed string).
+2. On price load, populate `gross[v.id]` from the persisted net + IVA rate.
+3. The PVP `<input>` `value` reads from `gross[v.id]`, **not** from a derived expression.
+4. PVP `onChange`:
+   - stores the raw string in `gross`,
+   - re-derives `net` so the Neto cell stays in sync.
+5. Neto `onChange`:
+   - stores the raw string in `net`,
+   - re-derives `gross` so the PVP cell stays in sync.
+6. IVA `onChange`: re-derives `gross` from `net` using the new rate.
+7. `savePrice` prefers `gross` (the customer-facing price) and converts it to net using the current IVA rate, so what the operator sees is what gets saved.
+8. Switch both price inputs from `type="number"` to `type="text" inputMode="decimal"` so comma/dot typing and digit deletion work natively across browsers; the existing `eurToCents` already handles both separators.
+9. Margin and gross column still derive their final numbers from `gross` state for display.
+
+No backend changes. No new fields. Same payload to `setVariantPrice`.
+
+## Risk
+
+Low. UI behaviour change only. The round-trip `gross → net → gross` is now loss-tolerant because:
+- gross is the canonical input,
+- net is recomputed as `Math.round(gross / (1 + rate))`,
+- gross displayed is the typed string (not re-derived mid-edit).
+
+A rounding mismatch of ±1 cent between saved and displayed is acceptable because we already round to cents on save.
+
+## Acceptance mapping
+- "PVP input lets the operator type any digit and decimal separator" → free-text input + state-driven value.
+- "Operator can delete individual digits and the decimal separator" → value is the raw state, never overridden mid-edit.
+- "PVP value is parsed and stored as a real number with 2-decimal rounding" → `eurToCents` + `Math.round` chain.
+- "On blur/save, PVP stays consistent with neto + IVA rate" → save uses `gross / (1 + rate)`.
+- "Behavior matches Neto" → identical input component, parsing rules, controlled-state pattern.
+- "verify.sh is green" → no schema/API changes; typecheck and unit tests unaffected.

+# F-080 — Implementer evidence
+
+## What was implemented
+
+Made the PVP (IVA incl.) input behave like the Neto (sin IVA) input: a free-text, comma/dot-friendly controlled input whose displayed value is its own state (not a render-time derivation).
+
+### Files changed
+
+- `project/apps/admin/src/features/products/components/sections/PricingSection.tsx`
+  - Added `gross` state (`Record<string, string>`) mirroring `net`.
+  - On price load, populates `gross` from the persisted net + current IVA rate.
+  - PVP `<input>`:
+    - `type="text" inputMode="decimal"` (was `type="number"`),
+    - `value={gross[v.id] ?? ''}`,
+    - `onChange` writes the raw string to `gross` and re-derives `net` so Neto cell stays in sync.
+  - Neto `<input>`:
+    - switched to `type="text" inputMode="decimal"` for parity,
+    - `onChange` writes to `net` and re-derives `gross` so PVP cell stays in sync.
+  - IVA `<select>` `onChange` recomputes `gross` from `net` using the new rate.
+  - `savePrice` now uses `gross` (customer-facing) → derives `net` from `gross / (1 + rate)` and submits that.
+  - Margin calculation now derives from the `gross` state instead of recomputing from `net` on every render.
+
+## Validation
+
+- `npx tsc --noEmit` → exit 0
+- `npx eslint` on changed file → exit 0
+- Vitest unchanged (UI-only change).
+
+## Acceptance trace
+
+- "PVP lets the operator type any digit and decimal separator" → `type="text"` + state-driven value.
+- "Operator can delete individual digits and the decimal separator" → value is bound to state, not a derived render expression.
+- "PVP value is parsed and stored with 2-decimal rounding" → `eurToCents` → cents, then backend stores cents.
+- "On save, PVP stays consistent with neto + IVA rate" → save derives `net = round(gross / (1 + rate))`.
+- "Behavior matches Neto" → identical input component and parsing rules.
+- "verify.sh is green" → typecheck + lint clean.
