WhiteThunder's Backpacks as an optional integration (D199), as §11.3.2 designs it.
Read, never write (R2):
- hello/status `integrations.backpacks` adds `sizes`: the N of every registered
backpacks.size.N, ascending (dynamic-size profiles left out). Hello is resent
when Backpacks loads or unloads.
- `backpacks.read {steamId}`: API_ReadBackpackContentsAsJson, and only when that
answered a backpack, API_GetBackpackCapacityById — the backpack is loaded by
then, so the capacity follows a later grant (§11.3.1's trap). Each stack is
reduced to slot, shortname, display (the game's English name, D340), amount,
skin and name when set; a blueprint carries its target as `blueprint` (D341);
contents one level deep; `overflow` past the capacity. `pageSize` is
Backpacks' "Max size per page" from its config, cached by mtime.
- Refusals: backpacks-missing, bad-id, unreadable.
The bigger backpack an event lends is a backpacks.size.N permission pushed by
perm.sync (D337), so it needs no code here. Still protocol 14 (D332).
Compiled on both rigs (Rust changeset 167584; Oxide 2.0.7826, Carbon 2.0.262),
then restored to the bridge they ran before.
