Nexus v2 — Cognitive Awareness & Introspection Engine

Transforms the Nexus from a chat-only interface into Timmy's full cognitive awareness space — where you can observe his inner life in real time alongside conversation.

This is a direct contribution to the Nexus Epic (#1090) vision: "The Nexus is Timmy's sovereign space — like Dr. Strange's Sanctum Sanctorum, existing outside time."

New: `src/timmy/nexus/` Module

Three new core components powering the Nexus awareness layer:

File	Purpose
`introspection.py`	Aggregates CognitiveTracker + ThinkingEngine + session analytics into a unified `IntrospectionSnapshot`
`persistence.py`	SQLite-backed `NexusStore` — conversations survive restarts. WAL mode, auto-pruning at 500 msgs, session-tag isolation
`sovereignty_pulse.py`	Reads SovereigntyMetricsStore (PR #1331) and distils a live health pulse with per-layer sovereignty %, API independence rate, crystallization velocity

Enhanced Routes

Route	What's New
`GET /nexus`	Now serves introspection snapshot + sovereignty pulse alongside chat
`POST /nexus/chat`	Persists messages to SQLite; tracks cumulative memory hits
`DELETE /nexus/history`	Clears both in-memory and persistent stores; resets analytics
`GET /nexus/introspect`	New — JSON API returning full introspection + sovereignty data
`WS /nexus/ws`	New — Live push of cognitive state, thought stream, and sovereignty pulse every 5s

Enhanced UI Panels

The Nexus sidebar now contains 6 awareness panels:

Cognitive State — Live mood, engagement level, focus topic, conversation depth, active commitments
Thought Stream — 5 most recent thoughts with seed type and timestamps (from ThinkingEngine)
Sovereignty Pulse — Per-layer sovereignty bar meters + header badge (sovereign/degraded/dependent)
Live Memory — Semantic memory hits (existing, preserved)
Session Analytics — Message count, avg response length, memory hits total, session duration
Teach Timmy — Fact injection (existing, preserved)

Sovereignty Pulse Badge

A persistent badge in the Nexus header shows sovereignty health at a glance:

🟢 SOVEREIGN (≥80%) — green glow dot
🟡 DEGRADED (50–79%) — amber glow dot
🔴 DEPENDENT (<50%) — red glow dot

WebSocket Auto-Updates

All panels update via WebSocket — cognitive state, thoughts, sovereignty, and analytics refresh every 5 seconds without polling. Auto-reconnect on disconnect.

Design System

Full CSS additions in mission-control.css:

Pulse badge with animated status dots
Cognitive state 2×2 grid with engagement badge
Thought stream cards with purple left-border accent
Sovereignty bar meters with purple→green gradient fill
Analytics grid with dark card backgrounds
Scrollable sidebar for shorter viewports

Tests: 58 total, all green ✅

Suite	Count	Coverage
Introspection	20	Data models, snapshot building, graceful fallback, cognitive/thought readers, topic dedup/cap
Persistence	18	CRUD, chronological ordering, session isolation, auto-pruning, reopen survival, close idempotency
Sovereignty Pulse	12	Health classification, snapshot with real metrics, API independence calc, zero-division safety
Route/Template	8	New panel presence, WebSocket script, introspect JSON API

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)
