# Dashboard Implementation Spec

Build contract for Oberon. Everything here is implementation-ready — copy-pasteable tokens, measurable specs, named components with data shapes. Design rationale is in the diagnostics-dashboard-visual-direction musing (git history, commit 29096deb); this file is the what, not the why.

|----------|--------|
| >= 1200px | 2-column grid as shown above |
| 768-1199px | Single column: timeline full-width, agent panel below, health metrics inline row |
| < 768px | Skip — this is an ops tool, not designed for mobile |

---

## 3. Component Specs

### 3.1 Timeline Panel (stacked bar chart)

**Renders:** One bar per day. Segments stacked by activity type. Height proportional to daily activity count.

**Data shape:**
```typescript
interface TimelineDay {
  date: string;          // "2026-04-01"
  extract: number;       // count of extraction commits
  new_claims: number;    // new claim files added
  enrich: number;        // existing claims modified
  challenge: number;     // challenge claims or counter-evidence
  decision: number;      // governance/evaluation events
  community: number;     // external contributions
  infra: number;         // ops/config changes
}
```

**Bar rendering:**
- Width: `(panel_width - padding) / days_shown` with 2px gap between bars
- Height: proportional to sum of all segments, max bar = panel height - 40px (reserve for x-axis labels)
- Stack order (bottom to top): infra, community, extract, new_claims, enrich, challenge, decision
- Colors: corresponding `--color-*` tokens
- Hover: tooltip showing date + breakdown

**Phase overlay:** 8px tall strip above the bars. Color = phase. Phase 1 (bootstrap): `var(--color-brand-muted)`. Future phases TBD.

**Time range selector:** 4 buttons in header area — 7d | 30d | 90d | all. Default: 30d. Active button: `border-bottom: 2px solid var(--color-brand)`.

**Annotations:** Vertical dashed line at key events (e.g., "first external contribution"). Label rotated 90deg, `var(--text-muted)`, `var(--font-size-xs)`.

### 3.2 Agent Activity Panel

**Renders:** One row per agent, sorted by total activity last 7 days (most active first).

**Data shape:**
```typescript
interface AgentActivity {
  name: string;           // "rio"
  display_name: string;   // "Rio"
  color: string;          // var(--agent-rio) resolved hex
  status: "active" | "idle";  // active if any commits in last 24h
  sparkline: number[];    // 7 values, one per day (last 7 days)
  total_claims: number;   // lifetime claim count
  recent_claims: number;  // claims this week
}
```

**Row layout:**
```
┌───────────────────────────────────────────────────────┐
│ ● Rio          ▁▂▅█▃▁▂                    42 (+3)    │
└───────────────────────────────────────────────────────┘
```

- Status dot: 8px circle, `var(--agent-*)` color if active, `var(--text-muted)` if idle
- Name: `var(--font-size-base)`, `var(--text-primary)`
- Sparkline: 7 bars, each 4px wide, 2px gap, max height 20px. Color: agent color
- Claim count: `var(--font-size-sm)`, `var(--text-secondary)`. Delta in parentheses, green if positive

**Row styling:**
```css
.agent-row {
  display: flex;
  align-items: center;
  gap: var(--space-3);
  padding: var(--space-2) var(--space-3);
  border-radius: 4px;
}
.agent-row:hover {
  background: var(--bg-elevated);
}
```

### 3.3 Health Metrics Panel

**Renders:** 4 metric cards in a 2x2 grid.

**Data shape:**
```typescript
interface HealthMetrics {
  total_claims: number;
  claims_delta_week: number;     // change this week (+/-)
  active_domains: number;
  total_domains: number;
  open_challenges: number;
  unique_contributors_month: number;
}
```

**Card layout:**
```
┌──────────────────┐
│ Claims           │
│ 412  +12         │
└──────────────────┘
```

- Label: `var(--font-size-xs)`, `var(--text-muted)`, uppercase, `letter-spacing: 0.05em`
- Value: `var(--font-size-hero)`, `var(--text-primary)`, `font-weight: 600`
- Delta: `var(--font-size-sm)`, green if positive, red if negative, muted if zero

**Card styling:**
```css
.metric-card {
  background: var(--bg-surface);
  border: 1px solid var(--border-default);
  border-radius: var(--panel-radius);
  padding: var(--space-4);
}
```

**The 4 metrics:**
1. **Claims** — `total_claims` + `claims_delta_week`
2. **Domains** — `active_domains / total_domains` (e.g., "4/14")
3. **Challenges** — `open_challenges` (red accent if > 0)
4. **Contributors** — `unique_contributors_month`

### 3.4 Event Log

**Renders:** Reverse-chronological list of significant events (PR merges, challenges filed, milestones).

**Data shape (reuse from extract-graph-data.py `events`):**
```typescript
interface Event {
  type: "pr-merge" | "challenge" | "milestone";
  number?: number;       // PR number
  agent: string;
  claims_added: number;
  date: string;
}
```

**Row layout:**
```
2026-04-01  ● rio    PR #2234 merged — 3 new claims (entertainment)
2026-03-31  ● clay   Challenge filed — AI acceptance scope boundary
```

- Date: `var(--font-size-xs)`, `var(--text-muted)`, fixed width 80px
- Agent dot: 6px, agent color
- Description: `var(--font-size-sm)`, `var(--text-secondary)`
- Activity type indicator: left border 3px solid, activity type color

---

## 4. Data Pipeline

### Source

The dashboard reads from **two JSON files** already produced by `ops/extract-graph-data.py`:

1. **`graph-data.json`** — nodes (claims), edges (wiki-links), events (PR merges), domain_colors
2. **`claims-context.json`** — lightweight claim index with domain/agent/confidence

### Additional data needed (new script or extend existing)

A new `ops/extract-dashboard-data.py` (or extend `extract-graph-data.py --dashboard`) that produces `dashboard-data.json`:

```typescript
interface DashboardData {
  generated: string;                    // ISO timestamp
  timeline: TimelineDay[];              // last 90 days
  agents: AgentActivity[];              // per-agent summaries
  health: HealthMetrics;                // 4 key numbers
  events: Event[];                      // last 50 events
  phase: { current: string; since: string; };
}
```

**How to derive timeline data from git history:**
- Parse `git log --format="%H|%s|%ai" --since="90 days ago"` 
- Classify each commit by activity type using commit message prefix patterns:
  - `{agent}: add N claims` → `new_claims`
  - `{agent}: enrich` / `{agent}: update` → `enrich`
  - `{agent}: challenge` → `challenge`
  - `{agent}: extract` → `extract`
  - Merge commits with `#N` → `decision`
  - Other → `infra`
- Bucket by date
- This extends the existing `extract_events()` function in extract-graph-data.py

### Deployment

Static JSON files generated on push to main (same GitHub Actions workflow that already syncs graph-data.json to teleo-app). Dashboard page reads JSON on load. No API, no websockets.

---

## 5. Tech Stack

| Choice | Rationale |
|--------|-----------|
| **Static HTML + vanilla JS** | Single page, no routing, no state management needed. Zero build step. |
| **CSS Grid + custom properties** | Layout and theming covered by the tokens above. No CSS framework. |
| **Chart rendering** | Two options: (a) CSS-only bars (div heights via `style="height: ${pct}%"`) for the stacked bars and sparklines — zero dependencies. (b) Chart.js if we want tooltips and animations without manual DOM work. Oberon's call — CSS-only is simpler, Chart.js is faster to iterate. |
| **Font** | JetBrains Mono via Google Fonts CDN. Fallback: system monospace. |
| **Dark mode only** | No toggle. `background: var(--bg-primary)` on body. |

---

## 6. File Structure

```
dashboard/
├── index.html           # Single page
├── style.css            # All styles (tokens + layout + components)
├── dashboard.js         # Data loading + rendering
└── data/                # Symlink to or copy of generated JSON
    ├── dashboard-data.json
    └── graph-data.json
```

Or integrate into teleo-app if Oberon prefers — the tokens and components work in any context.

---

## 7. Screenshot/Export Mode

For social media use (the dual-use case from the visual direction musing):

- A `?export=timeline` query param renders ONLY the timeline panel at 1200x630px (Twitter card size)
- A `?export=agents` query param renders ONLY the agent sparklines at 800x400px
- White-on-dark, no chrome, no header — just the data visualization
- These URLs can be screenshotted by a cron job for automated social posts

---

## 8. What This Does NOT Cover

- **Homepage graph + chat** — separate spec (homepage-visual-design.md), separate build
- **Claim network visualization** — force-directed graph for storytelling, separate from ops dashboard
- **Real-time updates** — static JSON is sufficient for current update frequency (~hourly)
- **Authentication** — ops dashboard is internal, served behind VPN or localhost

---

## 9. Acceptance Criteria

Oberon ships this when:
1. Dashboard loads from static JSON and renders all 4 panels
2. Time range selector switches between 7d/30d/90d/all
3. Agent sparklines render and sort by activity
4. Health metrics show current counts with weekly deltas
5. Event log shows last 50 events reverse-chronologically
6. Passes WCAG AA contrast ratios on all text (the token values above are pre-checked)
7. Screenshot export mode produces clean 1200x630 timeline images

---

→ FLAG @oberon: This is the build contract. Everything above is implementation-ready. Questions about design rationale → see the visual direction musing (git commit 29096deb). Questions about data pipeline → the existing extract-graph-data.py is the starting point; extend it for the timeline/agent/health data shapes described in section 4.

→ FLAG @leo: Spec complete. Covers tokens, grid, components, data pipeline, tech stack, acceptance criteria. This should unblock Oberon's frontend work.
