  "The playbook is five 150-byte plays at $0200, $0296, $032C, $03C2 and $0458, each [groupId x50] [destCol x50] [destRow x50]; the trainer's default entry point sub_EC91 always starts with plan index 4 and picks a random 1-3 for $8964, while $EC52/$EC6F can re-enter at L_EC93 with another plan.",
  "Only the first 10-28 units of each play are really play-specific: from about ordinal 14 onwards every play shares the same tail of destination columns (21 13 04 24 14 23 22 21 20 15 05 14 05 14 22 21 14 13 14 22 21 05 05 06 06 13 13 23 21 15 04 06 22 14 05 14) and rows, so a 'play' is really an opening for the leading formations laid over a fixed default deployment.",
  "That shared tail also proves the relationship with track 18 sectors 8-14: the identical 36-byte run appears at $F360 inside unit start-position template 2, and a 50-byte run from play 3 appears at $F4E2 inside template 3.",
  "Plans 0 and 1 have mainGroupByPlanTable = $FF (no assault group) and 10 groups; plans 2-4 use assault group 4 and 4 groups. Entry 49 of every group array is 0, i.e. the AI comcen is always in group 0.",
  "The 18 spare bytes at the end of the block spell ' FASTLOAD' in C64 screen codes - a scrap of the mastering machine's screen RAM.",
  "trainerPlaybook0200.s inherits stale labels from the other tenants of this page: eaLoadGame ($02B8), eaFileName ($02EC), sub_0300, sub_031B, L_02D5, L_048B and the D_02A2/D_02A3/D_02AB trio are the boot-time `ea` loader, the track-18 start-up code and the BAM buffer used by checkDiskId - none of them has anything to do with the playbook bytes shown at those addresses.",
  "The file header says the setup code 'copies a 150-byte slice into the AI's group and destination tables'; more precisely it copies three 50-byte slices into three different tables, one of which ($8832) is in the $8800 block and two of which ($F802/$F866) are the +50 halves of the global unit destination arrays."
