**RETIRED 2026-07-15.** Root was the hook/identity synchronous-git fanout (hertz RCA 03 → adapter v0.21.0 verified-env fast path). Post-fix measurement on this box (HFENDULEAM; "bigscreen" = ccs instance label only): `spt subnet join --help` = **0.029s**. The always-background binding is lifted — treat spt like any CLI; background only genuinely long-running verbs.

Residual truth that survives: list-shaped commands (`endpoint list`, bare picker) still carry the O(perches × p-branches) git fanout CLI-side until PROJECT-INDEX ships ([[spt-core-findings-backlog]]) — those specific verbs may still deserve backgrounding on high-perch boxes.
