@@ -14,6 +14,11 @@ Format based on [Keep a Changelog](https://keepachangelog.com/).
 - **Atlas interaction** — double-click system on reach map opens orbital view, double-click body opens regional heightmap, M closes atlas from any screen, ESC navigates back through screen stack
 - **Inline body detail panel** — clicking a body in the orbital view shows an info panel on the right with full-size globe artwork, body stats, and population; clicking another body swaps the panel
 - **Regional atlas wiki loading** — heightmaps and markers load directly from the wiki filesystem, fixing "TERRAIN DATA PENDING" for all bodies with authored heightmaps
+- **Agent-team coordination tools** — `SendMessage` plus `TaskList`/`TaskUpdate`/`TaskGet` added to all 21 agent definitions so custom subagents work as full teammates in tmux split panes (message the lead, claim/complete tasks, shut down cleanly); `TaskCreate` deliberately withheld to keep task creation with the lead
+- **`git-centralize-guard` hook** — PreToolUse hook blocking `.git`-mutating commands for agent-team teammates, keying on the `agent_type` field present only in teammate hook input; version control stays centralized to the team lead
+
+### Changed
+- `teammateMode` set to `auto` — teammates spawn in tmux split panes when the lead runs inside tmux, with graceful in-process fallback
 
 ### Fixed
 - Godot 4.6 type inference parse errors in `main.gd` (`var zoom`, `var speed`) that prevented the main scene from loading
