+# F-085 — Architect: /tax-rates TIPO column is not editable
+
+## Root cause
+
+`/admin/tax-rates` PATCH route (`project/src/modules/pricing/api/pricing.routes.ts`) only accepts `{ name, ratePercent, active }`; `appliesTo` is not in the body schema and not written to the DB. The admin page renders the column as plain `<td>{r.appliesTo}</td>`.
+
+## Design
+
+1. Extend the PATCH body Zod schema with `appliesTo: z.enum(['general','reduced','super-reduced']).optional()`. Server validates the value against the enum (no DB constraint, but rejection is fast and the error message is clear).
+2. Add a new UPDATE branch for `applies_to` mirroring the existing ones.
+3. In the admin page, the TIPO cell is now click-to-edit:
+   - Click `<button>` → switches to a `<select autoFocus>` with the three valid values.
+   - On `change`, if the new value differs, fire PATCH immediately and close edit mode.
+   - On `blur`, if value still equals the original, just close; if different and `change` already fired, no-op.
+4. Success path updates the row in-place (`rates.map(...)`).
+
+## Risk
+
+Low. Server-side enum validation; no SQL injection; no new deps.
+
+## Acceptance mapping
+- "TIPO cell enters edit mode on click and shows a select with allowed types" → button → select.
+- "Selecting a new type and confirming triggers PATCH /tax-rates/:id" → onChange path.
+- "Invalid types are rejected client and server side" → Zod enum on server; select restricts client.
+- "Successful change is reflected without a full page reload" → in-place state update.
+- "verify.sh is green" → typecheck + lint clean.
