+# Heartbeat State Template
+
+Use this file as the baseline for `~/self-improving/heartbeat-state.md`.
+It stores only lightweight run markers and maintenance notes.
+
+```markdown
+# Self-Improving Heartbeat State
+
+last_heartbeat_started_at: never
+last_reviewed_change_at: never
+last_heartbeat_result: never
+
+## Last actions
+- none yet
+```
+
+## Rules
+
+- update `last_heartbeat_started_at` at the beginning of every heartbeat
+- update `last_reviewed_change_at` only after a clean review of changed files
+- keep `last_actions` short and factual
+- never turn this file into another memory log
