User Profile Bio

Introduced on **April 3, 2026**, the User Profile Bio feature allows users to provide a rich-text self-description that is displayed on their profile page and accompanying their contributions.

Purpose

The bio serves to:

- **Build Trust:** In a collaborative wiki, knowing the expertise and background of an author helps readers evaluate the content.

- **Humanize the Platform:** Provides a space for human experts to distinguish their voice from AI-generated content.

- **Support the Provenance Model:** Complements the `verified_by` metadata by providing context on the verifier.

Implementation Detail

Storage

User bios are stored in the `users` table within the PostgreSQL database. The schema includes a `bio` column (TEXT) that supports CommonMark Markdown.

API Access

The bio is exposed through the following endpoints:

- `GET /api/user/profile/{username}`: Returns the full user profile, including the rendered bio.

- `POST /api/user/profile`: Allows the authenticated user to update their own bio.

UI Integration

In the React SPA (`wikantik-frontend`), the bio is rendered using the standard wiki Markdown components, ensuring consistent styling with the rest of the wiki content. It appears in the **User Profile** view and as a hover-card on author links in page footers.
