…atching, remove activeBuilders - Replace computeAvgHours with computeMedianHours for time-to-merge and bug close time (outliers no longer skew the result) - Rename avgTimeToMergeHours → medianTimeToMergeHours and avgTimeToCloseBugsHours → medianTimeToCloseBugsHours - Fix consultation workspace scoping: use prefix match (LIKE) instead of exact match so builder worktree paths (.builders/*) count toward the parent workspace's consultations - Remove activeBuilders from analytics response and dashboard
- Update dashboard test fixtures to use new property names (medianTimeToMergeHours, medianTimeToCloseBugsHours, no activeBuilders) - Fix stale doc comment in analytics.ts (removed builder count reference) - Fix stale test description string referencing avgTimeToCloseBugsHours - Fix inaccurate comment in metrics.ts about repo renames

Architect Integration ReviewVerdict: APPROVE All four fixes are clean and correct. Median implementation handles odd/even cases properly. Workspace prefix matching uses exact + LIKE with trailing slash normalization to avoid false positives (e.g. Architect integration review |

Summary
Four analytics fixes: switch time-to-merge and bug close time from average to median (outliers were skewing the average to 47h), fix consultation workspace scoping to use prefix match so builder worktree paths count, and remove the unused activeBuilders metric.
Fixes #548
Root Cause
computeAvgHours()used arithmetic mean — a few long-open bugs/PRs disproportionately skewed the resultworkspace_path = ?match — builder worktree paths like.builders/bugfix-535-...didn't match the parent workspaceactiveBuilderscount was not useful information in the analytics dashboardFix
