`tea issues edit --add-labels` and `--remove-labels` resolve names against
the repo's own label set only, so `Kind/*`, `Priority/*` and the rest of
the org set match nothing. The command exits 0, prints the issue and
changes nothing — no error to notice. Repo-local labels work, which makes
the failure look intermittent rather than categorical.
Upstream fixed this in v0.15 (`modules/task/labels.go` also queries
`ListOrgLabels`); nixpkgs pins 0.14.0, so the note expires on a bump.
Also states the general rule the miss came from: re-read a label change
before believing it. Exit 0 is not evidence.
