Extends at-rest encryption to shared spaces once per-group spaces exist. Objects in /spaces/<group> encrypt to all current members' age identities + the recovery recipient, so any member can decrypt.

  • Re-encrypt/rewrap on membership change (design: lazy vs eager).
  • Couples with the §5.4 authz work and group resolution.

Deferred from the v0.3 encryption probe.
