Finishes the sizing pass over every workload the deploy actually manages. Each request is at or above the container's p95 over the last seven days, so nothing is sized below what it is known to use, and each limit is between 1.6x and 5x the observed max, which is the figure that decides whether a burst gets an OOMKill. Some of these go up, and that is the point. adguard was holding 975M against a 500Mi request and netbox 962M against 512Mi, so both sat permanently above their own request and were standing eviction candidates on a node that has about 300M of headroom. Raising a request costs scheduler room; leaving it low costs the pod its place in the queue when the node gets tight. Others come down. loki ran with a 2Gi limit on 224M, gitea 1.5Gi on 305M, the authentik worker 1Gi on 305M, and a tail of single-purpose pods -- redis, glance, the two homepages, cfddns, session-keeper, the netbird dashboard, the loki gateway -- each reserved 4x to 16x more than they have ever touched. prometheus gets the opposite treatment: 768Mi/2560Mi, above its p95, because it compacts its TSDB in place and that is a burst worth budgeting for rather than throttling. Two of these limits are close enough to the observed max to be worth watching rather than trusting: adguard at 1.5x, and its DNS cache grows monotonically, so the ceiling is a date, not a margin. That was true before this change too; the pod sizing does not fix it and the cache needs bounding. CPU limits are untouched throughout. Leaving postgres alone as well: it sits in an uncommitted file that belongs to other work in progress. Verified: every request is at or above p95 and every limit above the observed max across all 74 containers, and 16/16 local gates pass.
