v0.2.0 — The Mirror Update 🪞

🪞 Student Self-View (Mirror) Layer

Students now see their own behavioral data — a mirror, not a report card. Pure SQL, zero LLM cost. The institutional-scale port of Cogito Directions A & B.

• Attention footprint — visited concepts overlay the knowledge graph with amber heat; "Mastery / My footprint" fill toggle
• Learning Rhythm — 7×24 heatmap of when you actually study, with pattern statements. Shades compare only against your own busiest hour, never against classmates
• Look Back card — a mirror you can veto. Appears only when asked. Template pattern statements, each with a "Sounds like me / Not quite" verdict button. Verdicts persist to a student-only LTM (selfview_snapshots) no instructor endpoint can read — the system's only ground-truth signal
• My Courses redesigned — xAPI activity counts as enrollment; full-width flip cards with labeled module bars; keyword search across names, codes, and module titles

🎨 UI & Docs

• New shared AmberSelect component — every native <select> replaced, one dropdown language site-wide
• Architecture docs split out and rewritten around user-visible surfaces, now bilingual: ARCHITECTURE.md / ARCHITECTURE.zh.md
• READMEs slimmed ~110 lines each

Red lines held throughout: no scores, no rankings, no class comparison in any student-facing view. The mirror speaks only when asked, and you decide if it's true.
