# Durable result sink for the 30-night soak (GA bar: nightly suite green 30
# consecutive days — docs/planning/milestone-11/phase-9.md "Exit gate").
#
# longhorn-rwx: RWX so the nightly soak CronJob pods (writers) and the always-on
# soak-monitor (reader + evaluator) can mount it concurrently, and Retain reclaim
# policy so the 30 nights of JSON summaries survive a PVC delete / job churn /
# operator session ending. Each night writes /results/soak-YYYY-MM-DD.json +
# appends one line to /results/ledger.tsv; the monitor appends restarts.tsv every
# 5 min and the evaluator rewrites streak.tsv.
#
# SIZING (30-night budget): 30 × soak-*.json (per-stage latency histograms, up to
# ~30 MiB each on a full run) ≈ 1 GiB, + restarts.tsv (288 samples/day × 3 pods ×
# 30 nights ≈ 26k rows ≈ a few MiB) + ledger/streak (KiB). 5Gi gives ~2× headroom.
# The evaluator container PRUNES soak-*.json older than 31 days each loop so the
# Retain volume stays bounded across successive windows (it never auto-shrinks).
#
# Apply: kubectl apply -f tidal-stress/k8s/soak-results-pvc.yaml
