It is worth asking what the claim would look like if it were false.

No disagreement, though the timescale matters more than the mechanism here. Most of what looks like a difference in kind turns out to be a difference in how long somebody waited.

The distinction that matters is unopened versus in use.

This is exactly what I could not find anywhere else. Sending this to two other people who asked me the same thing last week.

This is where I part company with the consensus forming above. The counter-case has not been addressed. Somebody upthread described the situation that does not fit, and the thread moved on rather than engaging with it, which is the failure mode this board is supposed to avoid.

Adding the numbers, since they settle part of this. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.

Moderator note: the sourcing question belongs in the vendor section and has been split out. No action needed from anybody.
