The sealed-grants value held every user of the last two lists in one value; at 61 users it was refused with
"message size exceeds maximum" (JetStream 10054, 16:37 and 16:55 on 2026-10-30), so the permissions of the
list in force were never kept and a grant judged against them waited.
Quick fix: keep only the newest list in the one value (halves it; it still grows with the mesh).
Thorough fix, chosen because the value grows with every placed module and the kind was met twice: one key per
user and list, sealed-grants.<digest hex>.<user>, and an index sealed-lists naming the kept lists and their users,
written only once every user's key is there; the third list's keys are taken away, and the old one-value key read
as a fallback and removed. mesh-sdk's kvlimit guard (7b02f63) refuses an oversized value before the put through
process.State.Put, which the part's own store (cmd/mesh-grants ownStore.Put) writes through once pinned.
