+## minting
+
+  - 3.14 release situation
+    - feature enabled in zos for health checks
+      - implemented in a way when when fbot nodes woke up
+        - attempt health cehck before network stack fully up
+        - creates chain of events in tfchain
+          - resolve in violation
+            - didn't wake up within 30 min
+    - Lee+Scott dsicussed this on github
+      - decision: fixing in minting code not appropriate
+        - not minting issue per se
+          - it's a zos issue
+    - Solution for now
+      - health checks disabled
+  - one month of minting affected: July
+      - numbers of node affected: TBD
+        - TODO: Scott will check the numbers of nodes affected
+        - TODO: Next meeting, we check the numbers of nodes affected and decide if we compensate
+
+## ZOS changes and minting
+
+  - change in zos needs to be compatible with minting
+    - if changes in zos, can potentially effect the minting
+      - e.g. order of events
+    - need to take special care that it is compatible with mitning
+      - e.g. fbot needs specific order of events
+
+## network filtering story
+
+  - it is paused until we have updated from ops
+    - we used 18.04 before and it led to issues
+    - fixed with ubuntu 24.04
+      - this is being worked on
+    - will take some time
+    - once fixed
+      - we can continue the testing
+  - priority
+    - get zos works with mycelium, node public IP, change in UI
+    - once we have ready images
+      - we can continue the network filtering story
