Perplexity Computer 77cdfde3a2 [perplexity] feat: Nexus v2 — Cognitive Awareness & Introspection Engine (#1090) ...

Extends the Nexus from a chat-only interface into a full cognitive
awareness space with real-time introspection, persistent sessions,
and sovereignty health monitoring.

New modules (src/timmy/nexus/):
- introspection.py — Aggregates CognitiveTracker, ThinkingEngine, and
  session analytics into a unified IntrospectionSnapshot. Surfaces mood,
  engagement, focus, commitments, and recent thoughts.
- persistence.py — SQLite-backed NexusStore so conversations survive
  process restarts. WAL mode, auto-pruning at 500 messages, session-tag
  isolation for future per-operator sessions.
- sovereignty_pulse.py — Reads the SovereigntyMetricsStore (PR #1331)
  and distils a live health pulse: per-layer sovereignty %, API
  independence rate, crystallization velocity.

Enhanced routes (src/dashboard/routes/nexus.py):
- GET  /nexus          — now serves introspection + pulse alongside chat
- POST /nexus/chat     — persists messages; tracks memory hits
- DELETE /nexus/history — clears both in-memory and SQLite stores
- GET  /nexus/introspect — JSON API for introspection + sovereignty data
- WS   /nexus/ws       — live push of cognitive state, thought stream,
                          and sovereignty pulse every 5 seconds

Enhanced template (nexus.html):
- Cognitive State panel (mood, engagement, focus, depth, commitments)
- Thought Stream viewer (5 most recent, seed type, timestamps)
- Sovereignty Pulse badge + detail panel (per-layer bars, stats)
- Session Analytics grid (message count, avg response, duration)
- WebSocket client with auto-reconnect for live updates

CSS (mission-control.css):
- Full Nexus v2 design system: pulse badges, health indicators,
  cognitive grid, thought stream cards, sovereignty bar meters,
  analytics grid, scrollable sidebar

Tests: 58 total (all green)
- 20 introspection tests (data models, snapshot, fallback, cognitive/thought readers)
- 18 persistence tests (CRUD, ordering, session tags, pruning, reopen)
- 12 sovereignty pulse tests (classify health, snapshot, API independence)
- 8 route/template tests (new panels, WebSocket script, introspect API)
