# Reserved for the remaining config-contract sections. No knob in this slice

# ── Remaining advanced env-only overrides ───────────────────────────────────
# These implemented values are still environment-only because they are host
# affinity, source-specific migration guards, or early runtime/bootstrap knobs.
# They do NOT belong in .env.example unless a deployment actually needs them.

# Embed job filesystem affinity. Compose sets the server container to
