+### 第七阶段：预测市场与操纵（7.1 预测市场、7.2 操纵检出）
+
+- 操纵检出（7.2 前半）：Poinbase 主池上玩家自己的现货单会累计"推价幅度"（对数），每晚随价格回归衰减，预测盘线索里能看到。幅度超过 2% 后，价格盘押中且方向和推价一致、或 PSC 永续平仓盈利且方向一致，按幅度被查（25% + 6 × (幅度 − 2%)，封顶 95%）：预测盘本金和收益全部没收、永续盈利没收，收益的一半记 FRAUD（上限 400），永续账户冻结 3 天，报纸出一条调查新闻。把规则从最初设想的"单日推价 ≥ 15%"改成了 2% 起：manipsim 显示价格盘阈值离现价只有 3–10%，尾盘买 58 的成本就能赢上千，≥ 15% 的线形同虚设。
+- 复核（ops `research/manipsim`，第 30 天）：先空后砸本身不赚——永续单边滑点加现货来回价差，砸盘 4000–20000 配 5000–20000 的空单平均净亏 66–4400，只有砸盘 4 万（推价 57%）配小空单才勉强为正；尾盘拉价格过价格盘阈值在没有检出时几乎稳赢（成本 40–125，净赚 570–1390，亏钱概率 ≈ 0），加检出后下注 ≤ 1000 平均只赚 100–240、亏钱概率 40–60%，下注 3000 平均亏 400–1500。
+- 游戏内验证：Poinbase 买 4000 CRC 的 PSC，推价累计 +15.1%，价格盘线索栏显示"你推价 +15.1%，易被查"。没有在游戏里验证：被查后的没收、新闻、永续冻结（单元测试覆盖预测盘判定；永续平仓的判定只有代码路径）。
+
 ### 第七阶段：预测市场与操纵（7.1 预测市场）
 
 - Web3 页"预测"子页（游戏第 8 天起，Web3 治理社区已买下）：每个盘口是一道是非题，开盘当天到窗口开始前可以买卖，窗口最后一天夜里结算；每天开门后补盘，同时开放 3–6 个，每天最多新开 2 个。资金走链上钱包的 CRC：买入、全部卖出都是合约调用，要在钱包上签名（和质押一样；买入的手续费在核对页选档、用 CRC 付，卖出用价值最高的币付）；持仓记在签名的钱包名下，结算时兑付回这个钱包，同一盘口各钱包只能押同一边，持仓上限和内幕判定按盘口合计（拆到几个钱包躲不过）。污点与成本按花掉的价值比例随资金进持仓，赢的钱继承押注资金的污点比例，卖回时按比例退。

DEX swaps also need a signature on the wallet. RatDigg miners (M1 / M2 / M3) are standalone machines with far more hash than a card and a lower power draw per hash; they need a battery, take modules and use no rig slots. Only the black market's miner dealers sell them, gated by black-market standing (M1 40, M2 60, M3 80), sometimes second-hand. When one burns out, repair it by putting electronic components in its repair slot in order; it comes back 20 health lower. Somewhere between day 50 and day 90 a "miner era" arrives, announced in the paper a few days earlier: the big farms halve their power costs, network hash climbs, GPU miners are diluted and low-end cards barely earn, while miners still do fine. Perps: the Perps tab on Poinbase uses your account CRC as margin, up to 5× on PSC and 3× on SPARK, one position per product, never long and short at once. Fills are worse than the quote (more so for bigger orders, like the spot pool) and opening and closing both cost a fee. Liquidation is checked only overnight against the day's average price: equity under 10% of notional wipes the margin. There is also a nightly funding payment; when the price is above its 7-day average, longs pay shorts. If a liquidation loses more than the margin, the insurance fund covers the gap; when it runs dry (a SPARK collapse can do that) winning positions are auto-deleveraged and give up half their profit; anything beyond that becomes your debt. Debt grows 2% a day, is repaid first from CRC in the account every night, blocks new positions and cash-outs, and after seven days items in your shop are seized to cover it; whatever is still short is written off and the perp account is banned for 30 days. Poinbase is a custodial account and can withdraw straight to the connected wallet; depositing from a wallet means sending to Poinbase's deposit address, which takes only CRC and PSC. More hardware wallets are sold by Dr. Jackson; drag one onto the trading terminal to add it, up to 5. The black market has cheaper ones. A wallet you no longer want can be destroyed on the Wallets page once its coins are moved out. Transfers pay a fee: slow, normal or fast, and gas prices rise and fall over roughly a week; when the network is congested fees rise and slow transactions may be dropped from the mempool. Check the full address before sending. Staking: CRA staked in the Revolution pool earns a daily rate that compounds into the stake; withdrawing means requesting first and waiting four days, with no interest while waiting and no way to take it early. The pool pays from a subsidy fund; when it runs low the rate is cut and word of big holders pulling out may spread. Treat that as a warning: once it collapses CRA is worthless within three days and four days of unlocking is too slow. The balance token SPARK can be minted and burned against CRA at the going price (with a fee); its price swings hard and crashes with the collapse. Staking, minting and burning are contract calls and need a signature on the wallet. Black market: coin only, no CRC, 30% above normal channels, with extra markup on high-tech goods and GPUs; the coin you pay leaves its share of taint with the seller and the goods carry no stolen tag; GPUs may be fake, inspect them yourself. Orders are cheaper than spot but take days and may be intercepted; merchants sell by type at their own price factor, 5+ items get 5% off and 10+ get 10% off, and a bulk merchant appears at random with the lowest prices but six days of waiting; escrow costs 5%, is released on delivery and refunded if the seller runs; advance release takes another 10% off, but a scammer keeps the money and only sellers with 30+ trades accept; the platform itself can rug, be taken over by enforcement, or a seller can be arrested, after which your orders get traced and crime logged; forum rumors can be warnings.
