 ## [Unreleased]
 
 ### Changed
+- Sprint 3 "Know" team briefings regenerated from database — all four files (server, client, joint, copy) now match actual sprint 3 ticket assignments
 - Ticketing database moved to shared worktree location (`../settledreach.db`) — eliminates binary merge conflicts across branches
 - All Python connectors use script-relative path resolution instead of `$REPO_ROOT` env var or git rev-parse
 - `$REPO_ROOT` environment variable removed — all scripts, skills, and docs use relative paths
