Access Changes

There will be no access changes

A sync failed yesterday, I'm rerunning it now. After that, the plan will rerun here.

you have to remove Elena's username from the member list @jxs (since now it's duplicated in two lists maintainer and member)

[galargh]

This is correct. The other issue that I mentioned - the one with sync - is already resolved.

thanks! Updated

Before merge, verify that all the following plans are correct. They will be applied as-is after the merge.

Terraform plans

libp2p

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
  ~ update in-place
  - destroy

Terraform will perform the following actions:

  # github_team_membership.this["alumni:elenaf9"] will be destroyed
  # (because key ["alumni:elenaf9"] is not in for_each map)
  - resource "github_team_membership" "this" {
      - etag     = "W/\"b55ec009c609a2c629e432edf9d41bd599f4f05f3af5587ab51790ac1f356505\"" -> null
      - id       = "6201424:elenaf9" -> null
      - role     = "member" -> null
      - team_id  = "6201424" -> null
      - username = "elenaf9" -> null
    }

  # github_team_membership.this["rust-libp2p maintainers:elenaf9"] will be updated in-place
  ~ resource "github_team_membership" "this" {
        id       = "11402594:elenaf9"
      ~ role     = "member" -> "maintainer"
        # (3 unchanged attributes hidden)
    }

Plan: 0 to add, 1 to change, 1 to destroy.
