Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
Databases can have a lot of user actions, self joining and running an
aggregate on millions of rows can be very costly
This optimisation will reduce the regular window of consistency down to 13
hours, this ensures the job runs much faster
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
Now that post numbers are monotonically increasing we should not need this job
Stuff should just self correct as users browser along
Corrected the job not to reset the disimissed posts in case we need it
