Playing Fruit Fly World costs nothing and asks for nothing: open the game, and you are in. Everything past that — a soul-bound record of taking part, an agent running the same model — is optional and additive, never a gate in front of the game.玩 Fruit Fly World 不花钱，也不要你给任何东西：打开游戏，你就在里面了。除此之外的一切——一份灵魂绑定的参与记录、一个跑同一套模型的 agent——都是可选和叠加的，永远不是挡在游戏前面的门槛。
Each layer below stands on its own. You can stop at the first one and lose nothing.下面每一层都能独立成立。你停在第一层，也不会失去什么。
Open /play and start a generation. No account, no install, no signature. Your lineage is saved in your own browser, and nothing about the game requires a chain.打开 /play 开始一代。不要账号、不用安装、不用签名。血脉存在你自己的浏览器里，游戏本身没有任何一环依赖链。
FREE · NO WALLET免费 · 无需钱包A Passport is a non-transferable ERC-721 that says you were here. It is a participation record, not a yield-bearing asset, and the game is fully playable without one.护照是一份不可转让的 ERC-721，用来记录你来过。它是参与记录，不是生息资产；没有它，游戏照样完整可玩。
OPTIONAL · SOUL-BOUND可选 · 灵魂绑定The public escape model and separate arena scoring rule are plain JavaScript with a documented interface, so an autonomous process can reproduce the published rules.公开的逃脱模型和独立的竞技场评分规则是不带构建步骤的 JavaScript，接口有文档，所以自主进程可以复现公开规则。
OPEN INTERFACE开放接口The Passport is an ERC-721 on Sepolia at 4,444 supply. It cannot be sold, so the only thing it can be is a record — and the price tiers exist to make taking part cheaper than not taking part.护照是 Sepolia 上的 ERC-721，总量 4,444。它不能卖，所以它唯一能成为的东西就是一份记录——而分档的存在，是为了让参与比不参与更便宜。
Pass a verified mission — a win in the arena, an agent run, a quoted post. Missions are listed with the mint.通过一个已验证任务——竞技场获胜、agent 运行、引用发帖。任务清单随铸造一起列出。
Enter a recorded arena window. The claim is the server-verified entry — you do not have to win. Local /play saves do not create this qualification.进入一个有记录的竞技场窗口。资格来自服务端验证的进入记录——不必赢下。本地 /play 存档不会产生这项资格。
Public mint. No task, no history, no wait.公开铸造。不需要任务、不需要历史、不需要等待。
Four rules that hold regardless of what happens to the project.四条规则，无论项目后来怎样都成立。
The contract blocks transfer, approval, listing and gifting. One wallet, one Passport, permanently — which also means no secondary market and no floor price.合约禁止转让、授权、挂单和赠予。一个钱包一份护照，永久有效——这同时意味着没有二级市场，也没有地板价。
Signing in is a signature, not a transaction. The site never takes custody of anything and never asks for a private key.登录只是一次签名，不是一笔交易。本站从不托管任何东西，也从不索要私钥。
No token, no pool, no percentage and no date. The Passport records participation; it is not an investment and nothing here is an offer of a return. If an incentive layer ever ships, it arrives as a separate, clearly labelled design.没有代币、没有池子、没有比例、没有时间表。护照记录的是参与，不是投资标的，本页也不构成任何收益要约。如果将来有激励层，它会以独立、明确标注的设计形式出现。
The escape circuit, its synapse counts, the wiring check and the game's rules are all readable — you can reproduce the numbers instead of taking them on faith.逃脱回路、它的突触数、连线核对和游戏规则全部可读——你可以把数字复现出来，而不必凭信。
The playable lineage game, the connectome-inspired escape model, the reproducible wiring check, the deployed Genesis Passport and the documented agent interface.可玩的果蝇血统游戏、受连接组启发的逃脱模型、可复现的连线核对、已部署的 Genesis 护照，以及有文档的 agent 接口。
Deeper mutation behaviour, multi-predator encounters, and seeded daily challenges built on the same generation loop.更深入的突变行为、多捕食者遭遇，以及建立在同一套「一代」循环之上的每日种子挑战。
This is not a complete fruit-fly brain, not a neuron-by-neuron simulation, and not a financial product. No token, yield or future value is promised.这不是完整的果蝇大脑，不是逐神经元的仿真，也不是金融产品。不承诺任何代币、收益或未来价值。
