 ### 第九阶段：剧情与收尾
 
+- 黑市买货页重排（`ui-trial` 分支）：左栏是卖家列表（平台和各商家，选中行反色，商家写类型和缩写地址），右栏是 3 列货架；币种和数量不再摆在货架上方。点"购买"后右栏换成付款面板：数量（库存内 ×1 / ×5 / ×10）、付款方式（商家接受提前放款时才有）、合计、付款币种（该商家收的币）和"生成账单"；下面是自动换币——钱包里别的币（够付）按 8% 滑点换成商家收的币，一次合约签名完成（`BmAutoSwapSlip`）；没有够用的币时写明。上架费、改价费、一键上架同样在付款面板里选币（平台收 PSC、CRT、CRA）。各类商家收的币：硬件技术类 PSC / CRT，违禁和个人卖家 CRT / 匿名币，农业养殖水务酿酒 PSC / CRA（`Merchants.Accepts`，界面里限制，域层下单不限）。游戏内验证：平台买一件商品，CRC 自动换币 224.64 CRC → 2.0842 PSC（208 信用点等值）后成交，货进储藏区；直接生成账单显示收款地址和金额；商家货架切换和付款面板正常。没有验证：卖货页改价、一键上架的付款面板、英文界面、数量选择（库存只有 1 件）。
+- 钱包页按钮：操作键放到数据格右边的纸面上（和顶栏页签同样的黑色触控键，不再压在污点字段上）；选中行只反色数据格；状态"已连接"靠右。
 - 新手期调整：低端显卡算力提高——RTX 60 1.0 → 1.8 H、RX 70 0.8 → 1.4 H（价格、耗电不变）。开局送的一矿架一卡，第 1–7 天日均净收入 14 → 33（电网电价），第 15–30 天 6 → 18；再买满 4 张同款卡的矿架 33 → 82/天，每加一张约 10 天回本（原来 24 天）。每张卡每千瓦时的产出仍低于中高端，一个矿架只有 4 个槽位，满槽 4×RTX60 约 7 H，4×RTX70 是 20 H，中后期自然要换更高档次。ops `research/starter` 有各档位的逐段结果。
 - 手册补写出金审查的全部规则（界面不显示额度和命中概率：单笔 5 倍房租、7 天累计 15 倍房租、污点 10% 起、混币和被标记地址 +30%、上限 90%、轻度 / 重度的后果、手续费和税）和"销毁钱包前自己转出持仓与存款"。
 - 金融审查（agy 在独立分支做的数值审查，核实后采纳一部分；报告 ops `research/agy/i_finance.md`，新模拟器 `research/agy_fin/subsim`、`portfoliosim`）：

Mixer: pick a coin, amount and rounds; each round takes a fee and lowers taint, rounds equal days of waiting, and the coins come back to the same address; the more you deposit, the worse the cleaning. Hardware wallets: on-chain coins sit in PLEDGER hardware wallets, each with its own balances and taint; open and connect them on the terminal's Wallets page. The Web3 page's trading, black market and mixer use the connected wallet, and coin-paying customers and mining rewards go into it too. Payments (black market, mixer, Ponero desk, listing fees) start as an invoice on the terminal; type the payee address on the wallet and hold ✓ to sign. The last two characters of an address are a checksum, so a one-character typo is usually caught; once in a while it happens to be valid and the coins go to an address nobody uses. 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.
