# Agent Observatory — Mission Control Development Tracker

## Overview

The Agent Observatory is a Streamlit-based observability and exploration application for the KDD Data Agent Creative Track. It transforms agent reasoning into a professional, judge-facing "Mission Control" experience with dark theme, executive narratives, and actionable insights — all without modifying core agent logic.

**Repository**: `src/data_agent_baseline/observatory/`  
**Launch**: `streamlit run src/data_agent_baseline/observatory/app.py`  
**Artifacts**: `/data3/dataFAIR/kdd-dev/public/artifacts/runs/` (with fallback to `artifacts/runs/`)

### Current Task Intelligence IA (Phase 19C-H, 2026-07-01)

- Task Intelligence now uses five primary judge-oriented sections:
   - Summary
   - Reasoning & Replay
   - Evidence
   - Review & Reliability
   - Raw Trace
- Reasoning & Replay is grouped via nested subsections:
   - Reasoning Flow (existing DAG renderer)
   - Guided Step Inspector (existing Replay renderer)
- Review & Reliability is grouped via nested subsections:
   - Review Signals
   - Trust Calibration
   - Diagnosis & Verification
- Evidence continues to render Evidence & Provenance content, and Raw Trace remains the final advanced forensic section.
- Task Health Strip remains above the five primary sections.
- Grouped subsection failures are isolated so one failing renderer does not break sibling subsections.
- No runtime, evaluation, HITL execution-control, runner, or artifact-schema behavior changes were introduced by this IA consolidation.

## Mission Control Features

### Professional UI/UX
- **Dark professional theme** with gradient cards and status badges
- **Hero header** with run/task context and key metrics at a glance
- **Executive Summary Card** that tells the story, not just metrics
- **KPI Cards** with color-coded status indicators
- **Visual execution flow** showing stage progression
- **Bottleneck insights** automatically identifying performance issues
- **Clean sidebar** with compact context card and collapsible sections
- **Debug mode** with raw metrics hidden behind expanders

### Design Philosophy
1. **Story First**: Answer "What happened?", "Did it succeed?", "Can I trust it?", "Why?"
2. **Visual Hierarchy**: Header → Status → Insights → Details
3. **Reduced Clutter**: No raw tables by default; everything in expanders
4. **Professional Polish**: CSS cards, badges, pills, section headers
5. **Judge-Ready**: Presentation suitable for executive stakeholders and competition judges

## Phase Completion Log

### Phase 1: Foundation & Core Loaders ✅
**Status**: Complete  
**Date**: 2026-06-16  
**Execution Time**: ~1 hour

**Files Created**:
- ✅ `src/data_agent_baseline/observatory/__init__.py` — Package initialization (exports RunDiscovery, TaskDiscovery, ArtifactFinder, ArtifactLoader, RunLoader, etc.)
- ✅ `src/data_agent_baseline/observatory/data_models.py` — Normalized dataclasses (TraceEvent, NormalizedTask, NormalizedRun, MetricNormalizer, NormalizePhases)
- ✅ `src/data_agent_baseline/observatory/loaders.py` — Artifact discovery and loading (RunDiscovery, TaskDiscovery, ArtifactFinder, ArtifactLoader, RunLoader)
- ✅ `src/data_agent_baseline/observatory/trace_parser.py` — Trace parsing helpers (parse_trace_events, extract_question, extract_final_answer, and utilities)

**Verification Results**:
- ✅ All imports successful
- ✅ RunDiscovery: finds 175 runs in `/data3/dataFAIR/kdd-dev/public/artifacts/runs/`
- ✅ TaskDiscovery: finds 50 tasks in sample run 20260616T055650Z
- ✅ ArtifactLoader: successfully loads comprehensive_evaluation.csv, summary.json, trace.json
- ✅ TraceEventParser: parses 14 trace events, identifies 9 unique tools used
- ✅ MetricNormalizer: correctly maps old field names (execution_success) to new (task_success)

**Key Decisions Implemented**:
1. **Lazy loading**: Runs listed without reading traces (startup < 1s, O(n) folder scan)
2. **Default path**: `/data3/dataFAIR/kdd-dev/public/artifacts/runs/` with fallback to `artifacts/runs`
3. **Graceful degradation**: All loaders return None/empty on missing files
4. **Backward compatibility**: Support both old and new metric column names
5. **Defensive parsing**: Handle multiple trace schema variants (steps, events, messages, etc.)

**Testing Status**: Ready for unit tests in Phase 12

- ✅ Run discovery: Lists 175 runs with dropdown
- ✅ Task discovery: Lists 50 tasks per run with dropdown
- ✅ Session state: Caches run/task to avoid re-loading
- ✅ Tab structure: All 8 tabs present with placeholder content

**Key Features**:
1. **Interactive run selection** — Dropdown with 175 runs (most recent first)
2. **Task selection** — Dropdown with available tasks for selected run
3. **Artifact path configuration** — Text input with default path, fallback logic
4. **Run info panel** — Shows task count, timestamp, metadata
5. **Task info panel** — Shows status, success metric, score
6. **Artifact status indicator** — Checkmarks for trace.json, CSV, replay, provenance
7. **Session caching** — Lazy-load on selection; no repeated file reads
8. **Tab placeholder structure** — Phases 3-10 ready for implementation

**Design Decisions**:
- Use `st.session_state` for persistent selections within app session (not page reloads)
- Lazy-load: Discovery on startup (fast), run/task load on selection
- Expanders for run/task info to keep sidebar clean
- `@st.cache_data` not needed for loaders (small overhead)

**Performance**:
- Sidebar rendered: < 500ms
- Run discovery: ~100ms (cached)
- Run metadata load: < 500ms
- Task load: ~1-2s (includes trace parsing)

### Phase 17: Executive Summary Enhancement ✅
**Status**: Complete  
**Date**: 2026-06-17  
**Execution Time**: ~2 hours

**Objective**: Incorporate CLI exec-report narrative structure into Streamlit Mission Summary

**Files Modified**:
- ✅ `src/data_agent_baseline/observatory/overview_page.py` — Added comprehensive executive narrative

**New Helper Functions**:
1. `_extract_refinement_attempts(task)` — Extracts execution/refinement cycles from trace events
2. `_extract_decision_reasoning(task)` — Extracts strategy, target output, expected results
3. `_extract_deliverables(task, run)` — Extracts results file path and output columns

**New Executive Summary Section**:

Placed at **top of Mission Summary** (before Question/Answer cards), includes 4 professional blocks:

#### A. Mission Overview Block
- **Execution Status** (with colored badge)
- **Completion Time** (formatted as "Xm Ys")
- **Refinement Cycles** (attempt count)
- **Confidence Level** (derived from refinement count):
  - 1 attempt → "High confidence — succeeded on first attempt"
  - 2-3 attempts → "Moderate confidence — N refinement cycles"
  - 4+ attempts → "Multiple iterations — N refinement cycles"

#### B. Decision Reasoning Block (blue gradient card)
- 💡 **Strategy**: Extracted from plan reasoning (up to 500 chars)
- 📋 **Target Output**: Column names from output_columns
- 📊 **Expected Result**: Row count from expected_row_count
- Graceful fallback to question if no reasoning found

#### C. Execution & Refinement Timeline
- Professional table showing attempts
- Columns: **Attempt #**, **Status** (Pass/Refine), **Insight / Action Taken**
- Extracts insights from trace events:
  - Feedback messages
  - Error descriptions
  - Verification results
  - Success confirmations
- Color-coded: Green (✓ Pass), Yellow (⟳ Refine)
- Shows "No refinement cycles detected" if none found

#### D. Deliverables Block (green gradient card)
- 📁 **Results File**: Full path to prediction.csv
- 📊 **Output Columns**: Comma-separated column list
- ⚠️ **Status**: Warning if task failed
- 📁 **Output Directory**: Shown if no prediction file

**Terminology Updates in KPI Cards**:
- "OUTCOME" → "EXECUTION STATUS"
- "TRUST" → "VERIFICATION"
- "TASK SCORE" (unchanged)
- "RUNTIME" (unchanged)

**Visual Design**:
- Mission Overview: Clean table with aligned labels
- Decision Reasoning: Blue gradient background, left border accent
- Timeline: Professional table with borders and hover effects
- Deliverables: Green gradient background, left border accent
- All cards use dark theme with proper spacing

**Data Extraction Strategy**:
1. **Refinement Attempts**: Parse trace_events for execute/critic/verify/refine events
2. **Decision Reasoning**: Extract from raw_trace → plan_reasoning, output_columns, expected_row_count
3. **Deliverables**: Construct path from run.base_path + task_id, extract columns from trace

**Graceful Degradation**:
- Missing reasoning → Shows "No refinement cycles detected"
- Missing strategy → Falls back to question text
- Missing deliverables → Shows output directory instead
- All sections handle None/empty values gracefully

**Page Structure After Enhancement**:
1. Compact Header (status pills + metrics)
2. **Executive Summary** ← NEW comprehensive 4-block section
3. Question Card
4. Answer Card  
5. KPI Cards (with updated labels)
6. Execution Story
7. Debug sections (collapsed)

**Benefits**:
- **Judge-Facing**: Immediately explains what happened in <10 seconds
- **Narrative Structure**: Mirrors CLI exec-report (executive_reporter.py)
- **Comprehensive**: Covers reasoning, execution, and deliverables
- **Professional**: Clean cards, gradients, proper typography
- **Production Ready**: No raw JSON, all details in expanders

**Verification Results**:
- ✅ All helper functions import successfully
- ✅ Executive Summary renders properly
- ✅ Timeline extracts attempts from trace events
- ✅ Reasoning block shows strategy when available
- ✅ Deliverables block shows file paths
- ✅ No errors with missing data (graceful degradation works)
- ✅ Professional appearance maintained

4. **Demo / Future Proof** — Checkpoint/rerun/comparison/evidence workflows

**Technical Excellence**:
- Lazy loading for fast startup (< 1s discovery)
- Session state caching (no repeated file reads)
- Graceful degradation (handles missing data)
- Backward compatibility (old/new metric names)
- 13 passing unit tests
- Production-ready code quality

---

## Quick Start

```bash
# Launch the Observatory
streamlit run src/data_agent_baseline/observatory/app.py

# Or specify a port
streamlit run src/data_agent_baseline/observatory/app.py --server.port 8501
```

**What happens on launch:**
1. App auto-discovers runs from `/data3/dataFAIR/kdd-dev/public/artifacts/runs/`
2. Latest run is selected automatically
3. First task in that run is loaded automatically
4. Mission Summary displays immediately with full analysis

**To explore other runs/tasks:**
- Use the Run dropdown in the sidebar
- Use the Task dropdown in the sidebar
- All data loads instantly from cache when available

**To change artifact path:**
- Scroll to bottom of sidebar
- Expand "Advanced Configuration"
- Enter new path and click "Update"

## Troubleshooting

**Issue**: "No runs found"
- **Solution**: Check artifact path in Advanced Configuration
- **Default**: `/data3/dataFAIR/kdd-dev/public/artifacts/runs/`
- **Fallback**: `artifacts/runs`

**Issue**: "Unable to load run data"
- **Solution**: Verify run folder exists and contains `summary.json` and/or `comprehensive_evaluation.csv`
- **Check**: File permissions

**Issue**: "Unable to load task data"
- **Solution**: Verify task folder exists (e.g., `task_11/`) and contains `trace.json`
- **Note**: App works even if some files are missing (graceful degradation)

**Issue**: Broken icon text visible
- **Solution**: Hard refresh browser (Ctrl+F5 or Cmd+Shift+R)
- **Note**: CSS should hide all Material icon leakage

**Issue**: App loads slowly
- **Solution**: First load takes 1-2s for discovery; subsequent loads are cached
- **Note**: Large runs (>100 tasks) may take longer to parse traces

## Known Issues & Design Notes

1. **Question extraction**: Sample task trace doesn't have top-level "question" field — will implement fallback extraction from trace structure
2. **Specialist data**: Early runs may lack full AAT data; high-level DAG will always work
3. **Confidence model**: Will use hybrid approach (existing data + derived components)
4. **Graph rendering**: Fallback to table if PyVis/Plotly unavailable
5. **Caching**: Phase 2 will use lightweight Streamlit @st.cache_data for run list

---

## Next Immediate Steps

1. ✅ **COMPLETE**: Mission Control UI/UX transformation (Phase 15)
2. ✅ **COMPLETE**: Blank page fix and launch utilities (Phase 16)
3. ✅ **COMPLETE**: Live Trace Flow UX refinements (Phase 16b — ongoing iteration)
4. **Optional**: Enhance other tab pages (DAG, Replay, Provenance, etc.) with Mission Control styling
5. **Optional**: Add difficulty classification logic based on task metrics
6. **Optional**: Add export functionality for executive summaries
7. **Future**: Add comparison view for multiple runs side-by-side

## Current State

**Version**: 0.4.0 — Live Trace Flow Edition  
**Status**: Production-ready for judge evaluation, executive review, and live run inspection  
**All Phases**: ✅ Complete (17/17 + Phase 16b refinements)  
**Launch**: `streamlit run src/data_agent_baseline/observatory/app.py`  
**Troubleshooting**: See [OBSERVATORY_TROUBLESHOOTING.md](OBSERVATORY_TROUBLESHOOTING.md)

### What's New in v0.4.0
- **Phase 19 navigation consolidation**: primary navigation now has four pages:
   - Run Launcher
   - Run Intelligence (with Run Health Summary + Trajectory Intelligence)
   - Task Intelligence
   - Demo / Future Proof
- **Run Intelligence page structure**:
   - **Run Health Summary**: compact KPI cards (Harness Health, Execution Success Rate, Failed Tasks, Mean Score and related run KPIs) with inline tooltips
   - **Verification Summary**: compact verification cards with per-metric tooltip formulas and source-column provenance
   - **Reliability Diagnostics**:
      - Root Cause Distribution compact panel with severity metadata and task previews
      - Root-cause summary cards (failed/low-score tasks, diagnosed root causes, top root cause, no-root-cause count)
      - Root-cause task inspector (deep link only to Task Intelligence)
      - Raw root-cause table/task-id views moved behind toggles
  - **Trajectory Intelligence**: Full-run trajectory analysis including:
    - Trajectory KPI Snapshot: total trajectories/tasks, dominant patterns, mean length/branching/critic loops, success rates, recovery rates, replay artifact count
    - Dominant Trajectory Patterns: summary interpretation (Clean, Retry, Replan, Complex Recovery)
    - Phase Timeline & Token Economics: per-phase breakdown with time%, token counts, tool calls/failures, confidence
    - Recovery / Self-Correction Flow: first-try/recovery rates, retries/replans by source
      - Coordinator Decision Visibility + Trajectory Health Labels rendered as compact observability panels
      - Trajectory Examples preserved as visual insight section
   - **Recommended Tasks to Inspect**:
      - unified curated task selector across Representative Tasks + Trajectory Examples
      - single deep-link action: Open in Task Intelligence
      - no Replay/DAG/Failure Analysis buttons in Run Intelligence
  - **Detailed tables** (Summary/Detailed/Research modes): Task Outcomes, Failure Distribution, Resource Usage, Validation Diagnostics, Artifact Completeness
   - **Guided Rerun Cohort Analysis**: shown in Summary view when guided reruns exist
- **Task Intelligence shell**: Mission Summary is no longer top-level; task-level views are grouped into five internal sections (Summary, Reasoning & Replay, Evidence, Review & Reliability, Raw Trace).
- **Demo / Future Proof shell**: Checkpoint, rerun planning/comparison, evidence pack, and demo workflows are grouped in one page.
- **Fallback stability preserved**: Live Trace Flow and Guided Live Trace Flow remain available directly from the sidebar View selector, with no renderer internals refactored.
- **Primary-page cleanup**: Advanced / Fallback Views informational text was removed from the Run Intelligence app-shell area and moved to Task Intelligence guidance text.
- **Runtime behavior unchanged**: no execution, evaluation, HITL runtime, or artifact schema changes in this phase.
- **Phase 20 out of scope**: no natural-language artifact Q&A changes in this phase.
- **Live Trace Flow tab** (⚡): Start runs, attach to existing runs, inspect tasks live during execution
- **Run Intelligence no-eval fallback**: when evaluation artifacts are missing, Run Intelligence renders read-only execution telemetry sections plus explicit eval-v2 guidance (no in-page execution trigger)
- **Conditional Run Intelligence controls**: `View level` selector appears only when evaluation artifacts exist
- **Launcher-to-Intelligence handoff**: terminal runs expose a direct "Open Run Intelligence" action in Run Launcher
- **Clickable step buttons** in Live / Replay: each step is a button; clicking syncs Step Output Inspector
- **50:50 split** between Live / Replay and Step Output Inspector
- **Click-driven inspector**: no dropdown; governed solely by Live/Replay button click; refreshes only on task start/end transitions
- **Condensed run status** object-style line with icons: `Run Status | ▶️ Running | ✅ Completed | ❌ Failed | ⏳ Queued`
- **Running-task auto-selection**: task selector auto-follows the currently running task; user can override
- **Step button two-part display**: button line + caption (`<story_group> | Action - <Thought>`)
- **Key findings untruncated** in Evidence Table
- **500 ms poll interval** for live updates (previously 1 s)
- **Agent Reasoning Overlay** surfaced above Status Commentary
- **Auto-refresh always-on** (no user toggle required)

---

## Implementation Notes

- All parsing is defensive: handles missing/variant schemas gracefully
- No modifications to core agent reasoning logic; Observatory actions remain artifact-oriented (run launch, run attachment, and explicit eval-v2 trigger)
- Standalone under `src/data_agent_baseline/observatory/` (no coupling to existing visualization code)
- Load-on-demand architecture: scales to 150+ runs without upfront cost
- Session-based state in Streamlit (no persistent storage needed)
- Mission Control styling is pure CSS — no JavaScript dependencies
- All components use HTML/CSS injection via `st.markdown(unsafe_allow_html=True)`
- Backward compatible with all existing loaders and builders
