It's a very rare race condition, odds are very low that you were impacted. If you were, you would have noticed (heavy builds with files being moved around where suddenly files are zero).
Another major stumbling block for train signals once you get the basics down is segment length. Signals indicate whether the next segment is occupied, not whether any given train will fit in there (and potentially block a segment or intersection behind it.)
I frequently set up tracks with segments as large as my longest train, but then end up having to add an intersection here or there, breaking up segments into smaller sizes. This is the root of most of my train woes (aside from LTN issues, which are a whole other issue!)

That's what chain signals are for. If a train waiting at a signal causes issues, replace the previous signal with a chain signal to prevent the train from problematically waiting at the signal.
The threat model for every lambda user having a password manager does not cover breaking and entering[0]: they should write down their master password and keep it at home in their bedroom drawer.
Use biometrics where possible (e.g. bitwarden on Android has that option)
[0] maybe it does for you, working on some DoD-confidential docs, but your computer-illiterate aunt doesn't.
As for bio-metrics they are not possible on all devices, and some software will require you to enter the master password once in a while even if it's activated.
But even if it was not the case, if you loose your device, you need to setup the new one, and for that, you need the master password or have backups.
It's only now added as an interactive step in the install script. It has ~always been possible to create a crypto device with the install medium by dropping to a shell: https://www.openbsd.org/faq/faq14.html#softraidFDE
Unless you actually hit the maximum your building can sustain (heat, volume). Building datacenters is incredibly expensive, so reusing existing infrastructure and packing it with more is actually important.
