| 1 | # The outer memory wall of the memory-pressure containment design |
| 2 | # (2026-08-28 §2.2), moved here from carlos-edge.service by the isolated-exec |
| 3 | # design (§4.3): exec-backed instances used to be the edge's children, so a |
| 4 | # ceiling on the edge unit bounded the agent plus every awake instance at |
| 5 | # once. They are sibling units now, so the ceiling lives one level up, on |
| 6 | # a slice that holds the edge AND carlos-instances.slice, and bounds exactly |
| 7 | # what it bounded before. Borrowing between agent and tenants and the OOM |
| 8 | # candidate set (a tenant at OOMScoreAdjust=500 is picked before the agent) |
| 9 | # are unchanged. |
| 10 | # |
| 11 | # Percentages so one file fits a t4g.micro and a t4g.medium; 80% leaves what |
| 12 | # the box's other units (keymail, console, ssm, litestream, journald) use. |
