# Shared model-weight storage for all llama.cpp pods.
#
# All llamacpp pods are pinned to the NUCBox (roger-nucbox-evo-x2) via
# nodeSelector, so a single hostPath PV on that node is correct and matches the
# existing postgres hostPath pattern. GGUF files are large (10s of GB); baking
# them into images would be wasteful, and an initContainer downloads them
# idempotently on first boot instead.
#
# nodeAffinity keeps the PV bound to the NUCBox even if labels change later.
#
# IMPORTANT: capacity is only metadata for a hostPath volume — k8s does NOT
# enforce it and bumping it does NOT add physical disk space. The
# DeepSeek-V4-Flash-0731 UD-IQ1_M GGUF is ~87 GiB across 3 shards, so the
# hostPath filesystem (/data on the NUCBox) must physically have ~95 GiB free.
# The fetch-model initContainer checks free space and fails loudly if the disk
# is too small; expanding the disk is a host operation, not a manifest change.
