 ## 2025-06-25 - [Copy-to-Clipboard UX and Immediate Feedback]
 **Learning:** Adding a copy-to-clipboard feature for key user identifiers (like email or IDs) significantly reduces friction in user workflows. Implementing this with `navigator.clipboard.writeText` and providing immediate visual feedback via a toast notification ('Correo copiado al portapapeles') confirms success. Using icon-only buttons with explicit `aria-label` and `title` ensures the feature is both accessible and intuitive.
 **Action:** Always provide a copy-to-clipboard option for static text that users frequently need to reuse, and ensure immediate feedback is provided upon action.
+
+## 2025-01-15 - [Keyboard Efficiency and Discoverability in Flashcards]
+**Learning:** For high-repetition tasks like flashcard study, keyboard shortcuts (Space/Enter for flip, 1-4 for rating) dramatically improve user flow and "flow state" immersion. However, shortcuts must be discoverable; adding bracketed visual hints like "[Espacio]" or "[1]" directly to button labels, along with descriptive "aria-label" and "title" attributes, ensures accessibility and lowers the learning curve for power users.
+**Action:** Always include keyboard shortcuts for core repetitive loops and provide integrated visual hints for those shortcuts to ensure they aren't "hidden" features.
+
+## 2025-06-18 - [Standardized Accessibility and Password Visibility in V2 Auth Forms]
+**Learning:** In V2 authentication flows, maintaining feature parity between Login, Signup, and Forgot Password pages—specifically regarding password visibility toggles and label-input associations—ensures a predictable and accessible user experience. Missing `id` and `htmlFor` attributes on inputs breaks screen reader navigation even if the layout looks correct.
+**Action:** Always audit the full authentication suite (Login, Signup, Recovery) for accessibility parity and ensure interactive password fields consistently offer visibility toggles.
+
+## 2025-06-17 - [Accessible Progress Indicators and V2 Navigation Polish]
+**Learning:** For progress indicators to be truly accessible, they must include `role="progressbar"` along with `aria-valuenow`, `aria-valuemin`, and `aria-valuemax` attributes, allowing screen readers to accurately report status. In side-navigation rails, ensuring decorative icons are marked with `aria-hidden="true"` and the active link has `aria-current="page"` significantly improves screen reader navigation. Additionally, maintaining localization consistency (e.g., 'Inicio' vs 'Home') in new UI versions (V2) is essential for a cohesive user experience.
+**Action:** Always implement full ARIA attributes for progress components and audit new navigation structures for both accessibility markers and language consistency.
+
+## 2025-06-17 - [Accessible Checkboxes and Consistent Prop Spreading]
+**Learning:** Enhancing base form components like `CustomCheckbox` with standardized `required` indicators (visual asterisk and `aria-required`) and grid support (`s`, `m`, `l`, `xl`, `offset`) improves both accessibility and developer productivity. Ensuring that `...props` are consistently applied to the inner `input` regardless of the presence of a wrapper `div` maintains a predictable component API.
+**Action:** Always provide visual and semantic cues for mandatory fields and ensure consistent prop-spreading behavior in multi-layered components.

+
+## Testing Standards
+
+### Console Warning Interceptor
+All tests run through a global interceptor in `src/test/setupTests.js` that fails tests on specific console.error/console.warn patterns. This catches test-quality issues before they reach CI.
+
+**Blocked patterns (console.error):**
+| Pattern | Issue | Common Cause |
+|---|---|---|
+| `not wrapped in act` | Async state update after test ends | API mock resolves after `await waitFor(() => {})`; loading state mock never resolves |
+| `changing an uncontrolled` | Input rendered without `onChange` handler | Mock form with initial undefined `value`; component renders without controlled prop |
+| `does not recognize the.*prop` | Invalid prop passed to DOM element | Passing `noMargin` or other custom props directly to `<div>`/`<select>` |
+| `checked.*onChange` / `value.*onChange` | Missing onChange on controlled input | Render with `checked` or `value` but no `onChange` |
+| `Received \`.+?\` for a non-boolean attribute` | Boolean-like prop leaked to DOM | Passing `noMargin` or similar to DOM elements |
+| `Invalid DOM property` | Wrong prop casing on DOM element | Using camelCase prop that should be kebab-case |
+| `validateDOMNesting` | Invalid DOM nesting | `<a>` inside `<a>`, `<form>` inside `<form>`, etc. |
+| `Each child in a list should have a unique.*key` | Missing key in list render | Map over items without `key` prop |
+| `value prop on %s should not be null` | Null value on input | Passing `null` to `value` prop |
+
+**Blocked patterns (console.warn):** Same set (act, uncontrolled, prop leaks, keys).
+
+### Avoiding act() Warnings
+For "renders loading state initially" tests: make the primary API mock return a never-resolving promise so state never updates after render:
+
+```jsx
+ExamService.getCaso.mockReturnValue(new Promise(() => {})); // never resolves
+render(<SomeComponent />);
+// test assertions here — no async state updates will occur
+```
+
+For tests that trigger state updates (clicks, form submissions): end with `await waitFor(() => {})` to flush pending async effects:
+
+```jsx
+import { render, screen, fireEvent, waitFor } from '@testing-library/react';
+
+fireEvent.click(screen.getByText('Submit'));
+expect(screen.getByText('Saved')).toBeInTheDocument();
+await waitFor(() => {}); // flushes act() from state update
+```
+
+### Using `__SKIP_CONSOLE_CHECKS__`
+When a test **intentionally** triggers one of the blocked patterns (e.g., testing React's controlled/uncontrolled warning), set the flag before the action that triggers the warning:
+
+```jsx
+// Inside your test:
+globalThis.__SKIP_CONSOLE_CHECKS__ = true;
+// ... perform action that triggers expected warning ...
+globalThis.__SKIP_CONSOLE_CHECKS__ = false; // automatically reset in afterEach, but explicit reset is fine
+```
+
+This is rarely needed. Prefer fixing the underlying issue over skipping the check.
+
+### CI Enforcement
+The GitHub Actions workflow (`.github/workflows/node.js.yml`) runs a post-test grep check that fails CI if any blocked patterns appear in test output. The pre-commit hook (`hooks/pre-commit`) runs the full test suite locally before every commit.
+
+### Expected Console Output
+Tests that exercise error paths (e.g., API failures that display error alerts) may log to `console.error` as part of normal behavior. These are **allowed** and do not fail tests — only the specific warning patterns above are blocked.
+
+## Pre-commit Hook
+A pre-commit hook runs `npx vitest run` before every commit. To set up on a fresh clone:
+```bash
+cp hooks/pre-commit .git/hooks/ && chmod +x .git/hooks/pre-commit
+```
+To bypass temporarily: `git commit --no-verify`
