  "_comment": "Addon -> highest k8s minor each addon version supports. The preflight compat-gate (compat-gate.py) reads the RUNNING version of each addon and blocks a k8s upgrade whose target minor exceeds what that running version supports — so the chain auto-halts + alerts instead of breaking on an unsupported addon. Keep current; sources are the addons' own k8s compat matrices (last refreshed 2026-06-19 for the 1.34->1.36 catch-up). max_k8s keys are addon-version floors (major.minor); value is the highest k8s minor that floor supports.",
