So, you seem to suggest to go back to TRAINCON-1 so we can resume
careful landings.

what's not clear to me is what you suggest wrt to blocking promotion.
Please confirm whether its 1. or 2.:

1. declare this issue a non-blocker for one promotion, but a blocker
for next promotion?

2. continue block promotion, but keep landings flowing which would
risk delay promotion even if we find a fix today/monday?

...or something else?
