Seed examples — expected behaviour

Curated fixtures for the program picker. Folder layout mirrors the original ACE 2.4 prgs/ tree so the dropdown shows optgroups (Turtle, BenchMarks, Gfx, …). The .b demos themselves are David Benn’s programs from that distribution (not third-party). Host-only demos live under ACEBasicJS/. ACE root-level programs (e.g. hi.b) use the prgs group.

Phase 0 only runs simple PRINT "..." lines. Later phases must meet the expectations below (observable results in the host output / runtime).

window	ACEBasicJS/window.b	320×200 screen + titled window; close gadget (or Stop) quits.
window-input	ACEBasicJS/window-input.b	Type in the window after prompts; Enter submits.
graphics	ACEBasicJS/graphics.b	Lines, boxes, circles; wait for a key or close.
ackermann	BenchMarks/ackermann.b	Ackermann table via recursive SUB.
ahl	BenchMarks/ahl.b	Time / accuracy / random accumulator lines.
lines	BenchMarks/lines.b	Random lines; press a key when done.
loops	BenchMarks/loops.b	Timing lines for FOR / WHILE / REPEAT.
sieve	BenchMarks/sieve.b	Byte sieve banner + timing.
paint	Gfx/paint.b	Patterned triangle, flood-filled circle, solid boxes.
pattern2	Gfx/pattern2.b	Dithered window fill; close gadget quits (GADGET WAIT 0).
shuttle	Gfx/shuttle.b	Wireframe shuttle; enter 3 angles (try 40/80/120), then C redraw / Q quit.
fact	Misc/fact.b	Factorials until -1.
hi	hi.b	Coloured "Hi There!" spray; press q.
sound	Sound/sound.b	Tones / period sweep (unmute tab).
boxit	Turtle/boxit.b	Recursive boxed edges; press q.
bst	Turtle/bst.b	Binary search tree menu; Insert nodes then height/count/graph.
dragon	Turtle/dragon.b	Dragon curve; prompts for depth/sides.
flower	Turtle/flower.b	Flower; press q.
snowflake	Turtle/snowflake.b	Koch snowflake; prompts for depth/sides.
spiro	Turtle/spiro.b	SpiroGraph; press q (on phone: tap Keys to open the keyboard). Original MENU deferred.
torus	Turtle/torus.b	Nested turtle loops; press a key or close.
tree	Turtle/tree.b	Recursive tree; prompt is branch length in pixels (try 40, not 5 — base case is n<5); press q.

Intentionally not seeded yet

Program	Reason
ACE prgs/Gfx/* (beyond paint / pattern2 / shuttle)	Next; defer IFF/EHB/HAM
ACE prgs/welcome.b	Needs SAY / TRANSLATE$
ACE prgs/Library/hello.b	LIBRARY selective shims later
ACE prgs/IO/seq.b	File I/O demoted

Notes

• Comments starting with '.. or REM are ignored.
• Node smoke tests feed INPUT via inputLines on the runtime; the browser types on the active text surface (console or current window) and presses Enter to submit.
• Phase 4 Intuition programs draw into the Display panel’s screen host; CLI programs still use the console surface below.
• Browser ports of tight Amiga wait loops add SLEEP so the event loop can deliver keys.
• On phones/tablets, INKEY$ / quit keys need the Keys field under Display (opens the soft keyboard). Tap it, then press q.
• manifest.json folder field drives <optgroup> labels in the program picker.
