alex 9de77f7e5e lane O: 7 purpose-built saves - issued turn commands, node routes, research-roll-pending
Produces the game states several board rows were blocked on, and reads each
one back out of the save before claiming it.

- CD/TurnCommands_v5 decoded: three saves with issued orders (research target,
  research boost, build orders, system rates, colonize, fleet move). Layout in
  SAVE_FORMAT.md section 11; ids cross-checked against the same file's Sys/Flt.
- Waypoint type 3 (NodeRoute) now has 16 instances in one save and the player's
  own fleet is a mover in two. Type 2 is shown NOT to be produced by a Move
  order for either node-drive race (Zuul and Human both emit type 3).
- research_roll_pending true at load in two saves; the ProcessTurn gate constant
  at 0x00a2c788 is a float 0.5, so the flag survives into ProcessResearch only
  while progress/cost <= 0.5 at the start of the turn.
- Budget tail: construction and a large maintenance are live; Nexp is empty in
  all 11 saves and the 1.8 UI has no expense slider, so slot 12 looks dead.

VM140 restored to the original 8-file SavedGames set (autosaves byte-identical)
and left at the main menu; VM140 row set FREE.

Read out of dumps/sots.exe: .rdata bytes at 0x00a2c788 are 00 00 00 3f (float 0.5); the following word 0x00a2c78c is float 100.0, so this is a float32, NOT the double an 8-byte read would suggest (that reads as 5.28e13). CONSEQUENCE, measured on the live game: ResErrRoll survives into ProcessResearch only while progress/cost <= 0.5 at the START of the turn, so the OnTechResearched draw (0x0088df20) can fire only when a single turn supplies more than half the target tech's remaining cost.
