v0.3.0

v0.3.0

This release expands LENA from a student-facing demo into a fuller pilot experience with instructor tooling, course management, structured exports, improved UI polish, and additional security hardening (still excluding production authentication).

Highlights

• Instructor hub with demo authentication (single sign-in for insights + course admin).
• Course management UI: add/retire courses, upload documents, add link snapshots, and re-run ingestion without touching the server filesystem.
• Export data from the Insights interface: CSV or JSON, per-course or all courses, per-component or all components, date-range controls, and ZIP output for multi-file exports.
• UI refresh: improved typography (Inter), surfaces, and chart theming using the accent color.
• Security hardening pass aligned to OWASP guidance (excluding production auth): stricter upload handling, SSRF protections for link snapshots, tighter endpoint controls and headers.

Added

• Instructor login flow (demo-only) gating instructor-only endpoints and UI.
• Course admin endpoints and UI for managing courses and resources.
• Export modal and export API supporting CSV/JSON + multi-course ZIP + optional PII export (off by default, requires explicit enablement and encryption key).
• Demo seed logs so exports show structured example data immediately.

Changed

• Navigation and IA updates: “Instructors” replaces “Staff”, and instructor tooling is consolidated in one section.
• Documentation updates for demo auth behavior, course_id requirements, and deployment notes.
• Updated screenshots to match the current UI.

Security & Hardening Notes

• Added/expanded defenses for pilot deployments: rate limiting, security headers, feature flags around higher-risk endpoints, safer file upload handling, and SSRF protections for link snapshots.
• Authentication remains demo-only; production deployments must integrate institutional auth/SSO and proper RBAC.
