## 3. Echo6 Homepage — SearXNG Custom Theme

### Overview
The Echo6 homepage at `echo6.co` is a customized SearXNG instance (not a standalone static page). The default SearXNG UI is reskinned via CSS overlay, template overrides, and settings.yml changes to match the Echo6 cyberpunk brand.

### Implementation Approach
- **CSS overlay** (`echo6-custom.css`) — all color, font, layout, and component overrides
- **Logo replacement** — Echo6 logo replaces SearXNG default logo via volume mount or direct file copy
- **Template override** (`base.html`) — injects the top navigation bar, waffle menu JS, and custom footer
- **settings.yml** — instance name, theme, base URL configuration

### SearXNG Settings

```yaml
general:
  instance_name: "Echo6"

ui:
  default_theme: simple
  center_alignment: false   # results stretch to fill viewport
  theme_args:
    simple_style: dark

server:
  base_url: "https://echo6.co/"

brand:
  issue_url: false
  docs_url: false
  public_instances: false
  wiki_url: false
```

### Homepage Layout (Google.com-inspired)

```

```

- Homepage locked to viewport (no scroll, `overflow: hidden` on body.index)
- Logo + search bar vertically centered at ~35-40% from top using flexbox
- Default SearXNG text/wordmark hidden via CSS
- Results pages scroll normally (only homepage is viewport-locked)

### Top Navigation

## 4. Authentik Theme — Echo6 Branding

### Overview
The Authentik instance at `auth.echo6.co` is themed to match the Echo6 cyberpunk aesthetic. This covers the login flow, user dashboard, and admin interface.

### Brand Settings (Admin → System → Brands)

| Setting | Value |
|---------|-------|
| Branding title | `echo6` |
| Logo | Echo6 logo (uploaded via Customization → Files) |
| Favicon | Echo6 favicon |
| Theme | `dark` (forced — not automatic) |
| Custom CSS | Echo6 Authentik CSS (see below) |

### Flow Text Customization

| Flow | Title |
|------|-------|
| Authentication | `echo6 // login` |
| Invalidation | `echo6 // logout` |
| Recovery | `echo6 // recovery` |
| User settings | `echo6 // settings` |

### User Dashboard Layout

```yaml
settings:
  theme:
    base: dark
    cardLayout: 3-column
```

### CSS Customization Scope

The Authentik CSS overrides PatternFly (`pf-c-*`) components:
- Login flow: dark gradient background, cyan buttons, JetBrains Mono font
- Form inputs: dark backgrounds (`#111827`), cyan focus borders
- User dashboard: dark app cards with cyan hover borders
- Admin interface: dark sidebar, cyan active nav indicators
- Buttons: primary = Echo6 cyan with dark text, secondary = border-only
- Tables, tabs, modals, alerts, dropdowns — all themed
- Global font override to JetBrains Mono

### Application Icons
Each Authentik application has a matching service icon uploaded for the user dashboard tiles. Icons sourced from official project assets or cyberpunk-styled variants.

### Version Note
Authentik 2025.12.4 — custom CSS is applied via the Brand CSS field in System → Brands → Edit. The Shadow DOM CSS injection bug from 2025.12.0 is fixed in this version. Logo/favicon use the Files system (Customization → Files) rather than the old `/media/` mount path.

## 6. RECON — Knowledge Extraction Pipeline

### What It Does
Processes PDFs and web content → extracts structured knowledge concepts via Gemini AI → embeds into a vector database → provides RAG-augmented retrieval for Aurora.

### Pipeline Flow
```
PDF/Web Source → Extract Text → Gemini Enrichment → JSON (saved) → Embed (TEI) → Qdrant
```

### Key Stats

| Metric | Value |
|--------|-------|
| Total documents catalogued | ~13,239 PDFs + web sources |
| Documents complete | ~1,200+ (and growing) |
| Vectors in Qdrant | 95,000+ |
| Embedding throughput | 1,711 embeddings/sec (TEI) |
| Enrichment rate | ~100 docs/hour |
| Search latency | <10ms (HNSW index) |
| Full catalogue reprocess time | ~50 hours |
| Full catalogue cost | ~$135 (Gemini API) |

### Content Sources

| Source | Count | Description |
|--------|-------|-------------|
| Army Field Manuals | ~160 | Official Army doctrine (FM series) |
| Survival Companion Library | ~6,600 | Comprehensive survival/preparedness collection |
| Other documents | ~6,300 | Assorted reference, technical, trades |
| meshtastic.org | ~247 pages | Mesh communications documentation |
| ready.gov | ~5 pages | Emergency preparedness |

### Knowledge Domains (Aurora Taxonomy)

| Tier | Domain | Examples |
|------|--------|----------|
| 1 | Foundational Skills | Water, food, fire, shelter, first aid, navigation, security |
| 2 | Sustainment Systems | Long-term food/water/energy, medical stockpiling, tool maintenance |
| 3 | Defense & Military Tactics | Perimeter defense, small unit tactics, weapons, OPSEC |
| 4 | Off-Grid Systems | Power generation, water independence, thermal, comms infrastructure |
| 5 | Communications & Intelligence | Radio ops, mesh networking, SIGINT, OSINT, backup comms |
| 6 | Scenario Playbooks | Urban collapse, rural homesteading, bug-out, governance |

### Scenario Timescales

| Tag | Scope |
|-----|-------|
| tuesday_prepper | Next-week disruption (power outage, storm) |
| month_prepper | Extended disruption (supply chain, regional disaster) |
| year_prepper | Long-term grid-down |
| multi_year | Sustained collapse |
| eotwawki | End of the world as we know it |

### Concept Schema (22 fields per concept)
Core content, classification (domain/subdomain/skill level/scenario), provenance (source type, credibility score, verification status), reference (chapter, page, key facts), and technical metadata (deterministic IDs, embeddings, download URLs).

### Pipeline Architecture

| Stage | Workers | Bottleneck | Description |
|-------|---------|------------|-------------|
| Extract | 4 | CPU-bound | PyPDF2 → pdftotext → Tesseract → Gemini Vision (4-method fallback chain) |
| Enrich | 16 | I/O-bound (Gemini API) | 10-page windows → Gemini 2.0 Flash → structured JSON concepts |
| Embed | batch | I/O-bound (TEI) | bge-m3 1024-dim → Qdrant insert, 128/batch |
| Scanner | 1 | Hourly cron | Auto-discovers new PDFs from NFS mount |

### Resilience Features
- JSON-first: all Gemini extractions saved to disk before any DB insert
- Idempotent: content hashing prevents duplicate processing
- Recoverable: full Qdrant rebuild from JSON files alone
- Exponential backoff with jitter for API rate limits
- Window-level failure tolerance (partial document processing)
- Error classification (transient vs permanent)
- Automated backup to Contabo VPS every 6 hours

## 12. Design / Copy Hooks for Landing Page

### Tagline Ideas (raw material)
- 13,000+ documents processed into searchable knowledge
- 99 curated educational channels, GPU-transcoded and self-hosted
- AI-powered knowledge retrieval across military doctrine, survival, trades, and communications
- Fully self-hosted, zero cloud dependency for core services
- From PDF to actionable knowledge in 50 hours

### Key Differentiators
- **Self-hosted everything**: LLM, video, auth, DNS, monitoring — no SaaS dependencies
- **Knowledge pipeline**: Not just storing PDFs — extracting, structuring, and making them searchable via AI
- **GPU-accelerated**: Single RTX A4000 powers video transcoding, AI inference, embeddings, and transcription simultaneously (different silicon paths)
- **Resilient by design**: JSON-first storage, automated backups, full rebuild capability, exponential backoff
- **Curated content**: 99 hand-picked channels across tactical, trades, comms, medical, and education
- **Cohesive brand**: Cyberpunk aesthetic applied consistently across search, auth, and all services

### Numbers That Pop
- 95,000+ knowledge vectors
- 13,239 documents
- 99 video channels
- 1,711 embeddings/second
- <10ms search latency
- 22-field concept schema
- 6 knowledge domains
- 5 Proxmox nodes
- 18TB storage
- ~15.3TB video library
- 11 services in the waffle menu
