2. Hypothesis Detail Panel pages crash — undefined arrays and status on incomplete hypotheses — undefined arrays and status on incomplete hypotheses

File: tools/dashboard/src/components/panels/HypothesisDetailPanel.tsx

Problem, Segment, Unit Economics, and Value Proposition detail pages all crashed when clicked. The Value Proposition hypothesis is incomplete (no evidence, no assumptions) so several array properties were undefined. The panel accessed .length and .toLowerCase() on them directly without guards.

Seven lines changed:

// Before
{view.possibilitySpace.entries.length > 0 && (
  <li className={`possibility-item--${e.status.toLowerCase()}`}>
{view.possibilitySpace.eliminations.length > 0 && (
{view.evidence.length > 0 && (
  <span>{view.evidence.length}</span>
{view.researchSources.length > 0 && (
{view.assumptions.length > 0 && (
  <span>{view.assumptions.length}</span>
{view.channelStrategy && view.channelStrategy.channels.length > 0 && (

// After
{(view.possibilitySpace.entries?.length ?? 0) > 0 && (
  <li className={`possibility-item--${(e.status ?? '').toLowerCase()}`}>
{(view.possibilitySpace.eliminations?.length ?? 0) > 0 && (
{(view.evidence?.length ?? 0) > 0 && (
  <span>{view.evidence?.length}</span>
{(view.researchSources?.length ?? 0) > 0 && (
{(view.assumptions?.length ?? 0) > 0 && (
  <span>{view.assumptions?.length}</span>
{view.channelStrategy && (view.channelStrategy.channels?.length ?? 0) > 0 && (
