forgejo: 6Gi exceeded namespace quota, set to 4Gi (quota ceiling)
Some checks failed

The 3Gi->6Gi bump in ff3cc44a was rejected by the forgejo namespace tier-quota (requests.memory capped at 4Gi). With Guaranteed QoS the 6Gi request exceeded quota; FailedCreate left forgejo with 0 pods for ~6 min (git remote + OCI registry outage) until I patched the live Deployment back to a schedulable 4Gi. 4Gi is the most the quota allows and is still a headroom bump over the OOM-prone 3Gi. To go higher the tier-quota must be raised in the same change. This reconciles TF to the live 4Gi so the pending/next apply is a no-op rather than reverting to the quota-busting 6Gi.

# tier-quota caps requests.memory at 4Gi and Guaranteed QoS means
# request == limit, so a pod can request at most 4Gi. A first

# left forgejo with 0 pods until reverted -- do NOT raise memory

# registry was frozen + emptied 2026-06-13 (ADR-0002, ghcr), so the
# remaining spike is git ops / integrity-probe catalog walk / a
# possible leak; 4Gi should suffice. If it still OOMs, raise the
# tier-quota and this limit together.
