"""The READY page: the weekly worship checklist, checked against Planning Center.

Every couple of minutes this looks at this weekend's plan in Planning Center (PCO) and at
what is actually in place for it, and writes one verdict per checklist line into
snap.ready, which the READY page keys draw (check type "ready" in status_panel.py):

  tracks        the weekend's Ableton set exists and has a song group for every PCO song
  mix_foh       every song is mixed (a song whose tracks are all at 0 dB is not) and its
                stems go out to the console (Ext. Out), not to Master
  lights        the lighting cue track has a clip under every song
  tune          the Waves Tune clip that starts each song (a program change from the "Waves Tune - midi
                Program Change" clips) is the song's key in PCO
  routing       every stem goes where this location's template says (Keys -> Ext. Out 5/6 Keys), read live
                from Ableton over AbletonOSC, so tracks just dragged in count before the set is saved
  ears          no song stem's in-ear send (send A) is at -inf: dragged-in songs come in that way
  light_timing  every blinder flash and FX cue on the lighting track lands on the hit in the drum stem under it
                (a hit a few ms before or after the cue, with the cue itself on a quiet spot, is named)
  keys          every song is in the key PCO gives it: the set's locator for it ("3- JEHOVAH - B"), the pad
                clip under it ("B - WARM - CHURCHFRONT PADS") and a Finished Songs folder ("JEHOVAH [B]")
  prop          the ProPresenter playlist has every PCO item; lists in PCO item descriptions
                match the slides (MC announcements: one slide each; baptisms: every name)
  timecode      every song's presentation has a timeline, and PCO's LTC note for it is the timecode
                the tracks play at that song's start (worked out from the set's LTC clip and tempo map)
  backgrounds   every song's slides have a background (ProPresenter labels a slide with
                its media's file name)
  led_cross     every Resolume column Sunday's slides call up holds content, on the Service deck
                (slide -> macro -> RossTalk "CC page/row/col" to Companion -> Resolume column)
  lineup        the Band Lineup board (ProdDash) shows this plan and exactly the people on it
  mics          (a tap-to-confirm key) which mics this weekend needs, from PCO
  track_bundle  every location has this weekend's Ableton project folder on the shared drive
  prop_bundle   a ProPresenter bundle was saved to the locations' folder this week
  start         every service PCO lists this week (Sunday and special services such as First / Together
                Tuesday) has its Ableton set; the hold builds the missing ones (ableton_start.py)

What can be put right is put right by a hold (fix kind "ready", run_action below): re-sync
the lineup from PCO, put Resolume back on its deck, copy the tracks to a location that
has none, or simply look again now.

Nothing here writes to Companion, ProPresenter or Ableton's set; the Ableton set is read
from disk on the Tracks Mac (nice'd, and only when it changed), and the whole look is
skipped while a HyperDeck is recording.

Stdlib only; runs on the macOS /usr/bin/python3 (3.9).
