The spike on both rigs (Rust 25877464, Oxide 2.0.7826, Carbon 2.0.262,
Backpacks 3.17.8): the Carbon restart loss did not reproduce; the read
API's shape and cost; the capacity calls need an experimental setting;
a capacity cached without its backpack pins a size until reconnect; and
the take-back the org lead asked to see (overflow to inventory, or the
ground when full, on the owner's next open).
D337 leases a backpacks.size.N permission for the run through
rust_perm_run_grants instead of +N slots; D338 keeps Backpacks' own
take-back; D339 files the Carbon never-seen-id permission leak as
Rust-Plugins#32.
