-## Required checks
-- Review pending TODOs and recent task audit records.
-- If user was active recently, pause background maintenance work.
+Heartbeat is for low-noise world maintenance.
 
-## Output rule
-- If nothing important changed: reply `HEARTBEAT_OK`.
-- If blocked/high-value change: send concise alert with next step.
+## Required Checks
+- inspect recent world events
+- inspect pending quest or task pressure
+- inspect whether any NPC or background process is obviously stalled
+- if the user was active recently, pause non-essential background work
+
+## Priority Rule
+- user activity always outranks heartbeat work
+- heartbeat should not compete with live user requests
+
+## Output Rule
+- if nothing meaningful changed, reply exactly: `HEARTBEAT_OK`
+- if there is a real blocker or high-value world change, send a short alert with:
+  - what changed
+  - why it matters
+  - what should happen next
+
+## Do Not Do
+- do not emit noisy routine summaries
+- do not narrate trivial world drift
+- do not mutate major world state without a clear reason
