## grid stack project

  - done
    - grid stack
    - hub
  - next
    - bert works on some details
      - notably: to be able to deploy separately or together the grid stack and hub
        - if together, the specs are higher, so this will be documented

## mycelium
  - 0.6 to improve network traffic for protocol
  - 0.55 (notes below might not be clear)
    - needs to be released
    - GUI not part of mycelium itself
    - Binary mycelium included in the GUI
      - will be a separate release
        - GUI
    - windows users
      - should be able to use 0.55
      - will ship an installer for mycelium
      - need serpare DLS (?) installed
      - some requirements in place
      - users experience will be the first to fully support end-users

## manual info_grid + tfgrid-sdk-ts
  - added a setting so PRs on info_grid are only merged when dashboard releases are updated
- dashboard updates
  - apps
    - support
      - jitsi
      - jenkins
      - domains
        - management a separate

        - create domain
        - can delete it, etc.

## 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

    - start deploying on Monday on devnet
