Task 044: Security Fix & EP05 Data Quality

Status: DONE

Description

Fix HTML escaping vulnerability in scenario result rendering and populate missing computedDeltaV values in EP05 report.

Changes Made

1. XSS Fix in Scenario Result Rendering (templates.ts)

renderScenarioRow(): String values in ExplorationScenario.results were rendered without HTML escaping
Added escapeHtml(String(v)) for non-numeric result values
Added test case verifying HTML entities are properly escaped

2. EP05 computedDeltaV Population

ep05-transfer-02 (Brachistochrone): Set computedDeltaV: 15207 (300t most plausible scenario, matching cross-episode mass boundary analysis)
ep05-transfer-03 (Earth capture): Set computedDeltaV: 3.18 (LEO 400km capture, matching actual in-story outcome)

3. Test Coverage

Added escapes HTML in string result values test to templates.test.ts
Total tests: 831 TS + 79 Rust = 910

Files Modified

ts/src/templates.ts — escapeHtml fix in renderScenarioRow
ts/src/templates.test.ts — XSS escaping test
reports/data/episodes/ep05.json — computedDeltaV for transfers 02 and 03
