# tower-data — small PVC backing the OpStore JSON snapshot so the
# notification bell + Activity history survive tower-backend pod
# restarts (rollouts, OOMs, node drain). 200 ops × ~2 KB each =
# ~400 KB at full retention; 1 GiB is plenty of headroom and lets us
# add other Tower-side state files later (cache, audit log, etc.)
# without re-provisioning.
#
# Single-replica RWO is fine because tower-backend Deployment is
# single-replica (no leader election yet). When we move to multi-
# replica or HA Tower, replace with RWX or move state to Postgres.
