## 2026-06-13 - Added screen reader text for tooltip divs
**Learning:** When using `title` attributes on non-interactive elements like icon-only `div`s for tooltips, screen readers might not announce them properly because they aren't focusable. The visual tooltip is not enough for accessibility.
**Action:** Always add a visually hidden `<span className="sr-only">[Tooltip Text]</span>` inside non-interactive elements that rely on a `title` attribute so that screen readers have text content to announce.

## 2026-06-18 - Added keyboard accessibility to scrollable regions
**Learning:** Horizontally scrollable regions (like the `SectionRoadmap` component) are not accessible to keyboard-only users unless they can receive focus. Keyboard users must be able to focus the container to scroll its content using arrow keys.
**Action:** For proper keyboard accessibility in custom scrollable regions, always include `tabIndex={0}`, an appropriate `aria-label`, `role="region"`, and explicit focus visible styling (e.g., `focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-cyan-300`).

## 2026-06-19 - Internationalization
**Learning:** The desktop app uses i18n via json files located in `apps/desktop/src/locales/`
**Action:** When adding new text strings, make sure to add it to all locale files.

## 2026-06-25 - Native tooltips on disabled elements
**Learning:** Standard HTML `title` attributes used as tooltips do not render on elements that use Tailwind's `pointer-events-none` class, which is often applied to `disabled:` variants in Base UI and styled components.
**Action:** Do not rely on native `title` attributes for explaining disabled states on buttons with `pointer-events-none`. Instead, either use a custom tooltip component or ensure focus/interactive styles are preserved if an explanation is strictly required.

## 2024-07-01 - Testing components with focusable disabled button wrappers
**Learning:** When native disabled buttons are wrapped in a focusable `span` to provide accessible tooltips, tests that previously found and clicked the `button` (by temporarily removing the `disabled` attribute) may fail or become overly complex. It is cleaner and more accurate to query the wrapper element (e.g. via its `title`) and fire events on it, reflecting the actual accessible DOM structure.
**Action:** When testing UI components that wrap disabled buttons in a focusable span for accessibility (e.g., using a tooltip/title), use `screen.getByTitle(...)` to query the wrapper element for interactions like `fireEvent.click` rather than `screen.getByRole('button')`.

**Vulnerability:** CSV formula injection mitigation was naive, missing leading whitespace, tabs, and newlines.
**Learning:** Checking `/^[=+\-@]/` is not sufficient, as OWASP states that spaces and tabs before the formula triggers will also execute the formula in applications like Excel.
**Prevention:** Use a regex that allows leading whitespace (e.g. `/^[\s\uFEFF\xA0]*[=+\-@\t\r\n]/`) and include standalone tabs or new lines which are also injection vectors.

## 2026-06-29 - Path Traversal Vulnerability in Backend Audio Analysis
**Vulnerability:** Untrusted paths passed from the frontend for `audio_path` and `model_profile_path` were processed using `Path().expanduser()` and lacked validation against path traversal components like `..`, potentially exposing arbitrary local files.
**Learning:** Functions like `os.path.expanduser` or `Path().expanduser()` should not be used with untrusted inputs. Path traversal validation (e.g., checking for `..` sequences) must be explicit when dynamically accessing paths.
**Prevention:** Strictly sanitize untrusted dynamic paths, remove `.expanduser()`, and explicitly validate inputs (e.g., `if ".." in str(path): raise ValueError(...)`) to prevent path traversal risks, followed by automated CI vulnerability scanners (like Strix) validation.
