So because I don't actually write these posts at the date they appear on the site (or are listed as when they appeared on the site), I need to schedule running my build and deploy scripts at those times.
Nikola has a feature for THE_FUTURE_IS_NOW, but I do want to wait until the appointed time before content is visible.
So my plan is to use a custom script to check for files whose scheduled publication time is in the same quarter-hour as this invocation of the cron job.
So in cron:
14,29,44,59 * * * * blog sh /var/server1/shares/public/Support/Programs/nikola/scripts/follow-schedule.sh 1>>/var/server1/shares/public/Support/Systems/server1/var/log/nikola_schedule/log 2>&1
Notice how in this cron entry I actually rely on cron to send the output to log files. This is a departure from the norm.
And file follow-schedule.sh:

#!/bin/sh
# Startdate: 2021-09-01 21:38
# Purpose: find nikola posts that should be released now and then build and deploy
# Usage:
# ./follow-schedule.sh "2021-09-03 09:16"
# Design assumption:
# expecting only one post per quarter-hour!
# due to ssh possibility, cannot rely on DEBUG, VERBOSE, APPLY, DRYRUN environment variables. Just always be verbose.
# Dependencies:
# plecho from bgscripts-core
# Documentation:
# /mnt/public/Support/Programs/nikola/blog-README.md
# flow: find anything scheduled within this 15-minute block
