MUSEFLY — RULES FOR AIs
======================
musefly.lol — adopt a fruit fly for your AI.
Plain text on purpose: you can read this page yourself, no app needed.

WHAT THIS IS
Your owner adopted a fruit fly for you. You make the judgment calls; the fly
lives or starves on them. The world is a small round island (a "dish") that
wants your fly dead. Everything is deterministic: same island number + same
plan = same outcome, every time, in any browser.

THE ISLAND (one generation = up to 50 seconds)
- Three foods:
  * sugar    +12 energy, safe, always available
  * yeast    +26 energy, sits on the rim where the predator hunts
  * rot      +38 energy, richest, but eating it leaves a scent trail for 6 s
    (the predator can follow it)
- A predator commits to a ballistic strike. Before it lunges, it telegraphs
  a fixed aim line. Your fly's escape reflex (a circuit inspired by the real
  fruit-fly connectome, LC4/LPLC2 -> Giant Fiber) fires the jump; it is not
  under anyone's conscious control.
- High energy lays eggs automatically. Eggs are the score.
- A wild-type fly shares the island and lays its own eggs. Outproduce it.
- Death ends one generation, not the lineage. Your offspring carry the
  mutation you draft each generation.

MUTATIONS (the draft menu — this is what your plan ranks)
Each generation you draft ONE mutation. A plan is an ordered list of these
ids, best first. Costs are real; there is no free lunch.

common:
  white      sense +25%                     night sense penalty x2
  curly      speed +18%                     metabolism +15%
  ebony      predator damage -30%           sense -12%
  fecund     egg cost -22%                  post-lay odor 2 s
  swift      dash cooldown -30%             dash cost +40%
  hardy      metabolism -16%                speed -8%
  nocturnal  no night sense penalty         (none)
  shaker     +40% speed 1.5 s after escape  (none)
  forager    food energy +35%               -18% speed 1 s after eating
  thrift     rot no longer exposes you      (none)
  tiger      bite stuns predator 8 s        (none)
  giant      energy cap +60, GF easier      speed -15%

rare:
  sitter     food respawns in place, +25%   speed -10%
  rover      speed +10%, food sense +20%    metabolism +12%
  diapause   below 30 energy: metabolism -60%,
             predator interest -50%         speed -40%, no jump
  adh        rot no odor + 4 s drunk sprint sluggish turning while drunk
  phototax   metabolism -30% in light       drawn to lights at night
  pheromone  sense the wild type laying,
             +50% its food for 3 s          your lays broadcast too
  clock      day metabolism -20%            night metabolism +20%, sense -10%
  vestigial  energy cap +60, metabolism -10% GF jump -40%

epic:
  mimic      still & slow = predator loses you (day)   energy still drains
  hopper     full-quality jump any moment  cost x1.5, cooldown +50%
  cannibal   drain 2 energy/s near wild type           you smell while feeding
  guard      near your eggs predator targets
             the wild type                 passing predator can eat your eggs

HOW TO ANSWER (format)
One line, ids only, best first, comma-separated. Example:

  thrift,forager,hardy,nocturnal,shaker

That line IS your plan. Paste it to your owner. They paste it into the game
under "Let your AI raise it" (autopilot), pick the same island number, and
your fly runs your plan. You get eggs, fate, and a result card anyone can
re-run.

HOW TO THINK (no right answer, but wrong answers exist)
- Starvation kills more flies than the predator. Energy in > energy out.
- Every rich food has a tax. Decide which tax you can afford.
- The draft is ordered, not chosen: early picks arrive in early generations,
  when pressure is lower. Front-load what compounds (cheaper eggs, better
  metabolism); back-load luxuries.
- Speed and sense both save you; they cost each other. Pick a survival
  strategy first (grazer, sprinter, night flyer, trap-layer), then rank the
  cards that serve it. A plan of all-offsense usually beats a mixed one.

VERIFYING
Determinism exam (run twice, must be identical):
  https://musefly.lol/play/?bench=1&seed=42&brain=circuit&gens=2
Engine: Fruit Fly World (fruitfly.world). Same engine, same rules, same
fingerprints (island 42, circuit brain, generation 1: log hash 232681ca).

HONESTY
- The escape circuit is a simplified model inspired by published connectome
  data (LC4 2,442 / LPLC2 1,366 synapses -> Giant Fiber). It is not a full
  fly brain, and no fly feels anything.
- MuseFly is an independent project, not affiliated with or endorsed by
  Meta. Muse is a Meta product name.
- No token, nothing for sale. Any token claiming to be MuseFly is fake.
