The nested carrier in tasks/utils/load/app.yml inherited run_once from the apply of sys-stk-full's front-proxy include, so ansible-core wrote the stack host's carrier, keyed with its group_names, to every play host. Workers and the NFS server then missed their own key and re-rendered the whole applications SPOT on the next carrier and on every task that read it. run_once: false keeps each host's carrier.
The email lookup's onion check renders the provider host's group view, a key no carrier on a worker holds, so every lookup('email') there rendered the whole SPOT: 8-11 s per task, 17 tasks per swarm pass in the stalwart roundtrip. Hand the provider host's carrier, read untemplated via hostvars.raw_get, to that view; get_merged_applications still serves it only when its key matches and renders as before otherwise.
Each bug hid the other: fixing either alone only moves the misses. Together they remove about 142 s per swarm pass. With real ansible-playbook and HostVars the worker email task drops from 3.97 s to 0.77 s on ansible-core 2.20.6 and from 4.22 s to 0.70 s on 2.21.5 with the same result; the new tests fail with the reuse disabled.
