The 50m ceiling on the kubernetes-* script ops is justified by a comment enumerating what the failure path can spend, and the enumeration was both incomplete and reassuring in the wrong direction. It listed some collectors, said nothing about the node-join diagnostics or the image-cache diagnosis, carried a figure for the guest Talos capture that was half its real cost, and closed by asking the reader to keep the op above the sum, which no ceiling can do because the sum runs past what is left of the op on its own. It now names the phase budget as the thing that keeps the snapshot reachable and lists the collectors this ceiling covers, in the order the phase spends it. It states no sums and no per-collector figures. Why the budget is that number is derived once, beside the budget, and pointed at from here: a figure repeated across three files is a figure that drifts, and the drift is what the reader trusts. It also says what the ceiling does not promise. The budget bounds when a collector may start rather than when the phase ends; several collectors on this path carry no wall-clock bound at all; and the bringup's own waits already exceed this op on ceilings before a single diagnostic runs. So no worst case is claimed, because none can be stated while that holds. Assisted-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <f@lex.la>
