Task 208: Cross-Episode Visual Timeline

Status: DONE

Claimed by: Session (2026-02-28)

Completed: 2026-02-28

Priority: MEDIUM

Objective

Create a comprehensive cross-episode timeline visualization showing the full mission with all transfers, events, and key parameters.

Scope

1. Timeline chart: uPlot time-series chart spanning full mission (2241-09-05 → 2242-12-28)

- X-axis: mission elapsed time (days)

- Regions/bands for each episode

- Transfer events with ΔV markers

- Key narrative events (damage, cold sleep, plasmoid encounter)

1. Parameter tracks: Multiple synchronized time-series

- Ship velocity (heliocentric)

- Distance from Sun

- Accumulated ΔV

- Mass budget over time

- Radiation dose accumulation

- Nozzle remaining life

1. Orbital position track: Small orbital diagram showing ship position at each timestamp
2. Interactive: Scrub timeline to see ship position, click events to jump to episode analysis
3. Integration: Embed in cross-episode summary report

Key Files

• ts/src/timeline-analysis.ts (mission timeline computation)
• reports/data/summary/cross-episode.md (target report)
• ts/examples/uplot.html (uPlot example)
• ts/src/templates.ts (report rendering)

Dependencies

• Task 206 (455-day rethink) will change the timeline significantly
• Should be implemented AFTER Task 206 is resolved
