Step 7 of the way off eudplib: several programs in one map, programs for several players, and the walk surviving a player who leaves.

What changed

• own.ts: a run per program, and one for each player of a per-player program (owners checked against the map's slots and forces, as the Python side's owner_slots). Each run's graph has its own labels, scratch cells and variables, except shared ones, which belong to the program. Nothing is indexed by player while the game runs: the program is copied for each player. That is faster, and the payload grows with each copy.
• layout.ts: each run's @wake also checks that its player's list is not empty (eudplib's f_playerexist). The start-up goes in every player's triggers and links each list to an entry node of that player's own, alone in the list. A gate lets the walk into the runs only when every player before this one has an empty list.
  • Why it is shaped this way: measured in the lifted game, when a player leaves, the game empties their list by following next pointers, zeroing each node's two pointers and freeing it. Only the per-player entry is ever reachable from a list, and its next pointer is back at the list's end whenever the walk is not in it.
• emit.ts: prints to All Players or a force use the map's human and computer slots. hasLeft(p) is one condition, as eudplib's.
• build-own.mts: PEOPLE and // probe-players: as in build-fixture; the map's slots and forces passed through.
• Fixed: a program whose first statement jumps (let done = false) lost the jump in a map of our own, and the walk came in at the true side. eudplib's build was right.

Ledger: step 7, 27 of 28 (a program owned by P12 is refused on purpose, as Python refuses it). Nothing outside step 7 flipped to takes; three rows of steps 11 and 12 kept their refusals, now naming their own step's feature. New rows: array-per-player, recursion-per-player, owner-player-twelve, boolean-declared-first.

Lifted game, Remastered's weights	Own	eudplib
own-programs start: 5 runs of 4 programs	0.008 ms	1.077 ms
A frame where every run sleeps	< 0.001 ms	0.007 ms
fog-lib: the fog library's program, a frame	0.003 ms	0.007 ms

Checked

• probes/own-programs.ts: built both ways, the same lines at the same frames, every line ok.
• probes/fog-lib.ts: the tile flags hash the same in both builds every frame.
• probes/own-leaver.ts: a game of two people, either leaving at frame 40, each player's deaths the same in both builds at every frame.
• The step 7 rows against the simulator.
• npx vitest run: 1267 passed.

probes/own-programs.ts is in Maps/TrigScript as own-step7.scx with an answer sheet, for Remastered.
