Chain health 链健康
Is this chain alive, is it finalizing, and does its supply add up. Rendered from an observer node that learns over P2P like any peer — it is not a privileged view of the fleet. 这条链是否活着、是否在最终化、供给是否对得上。数据来自一个像任何 peer 一样通过 P2P 学习的观察节点——它不是对节点群的特权视角。

Finality最终性
Two finalized heads, kept apart on purpose. Head #1 is the committee tracker's view and does not survive a restart. Head #3 is the one that does. 两个已最终化的 head，刻意分开呈现。Head #1 是委员会追踪器的视图，活不过重启；Head #3 是能活过重启的那一个。

Checkpoint ticker检查点走势
| height高度 | fidfid | span跨度 |
|---|
span is the height delta from the previous finalized checkpoint, so a span wider than the cadence means degraded time was crossed. The first checkpoint of a history has nothing before it and shows a named absence rather than a zero. 跨度是与上一个已最终化检查点的高度差，所以跨度大于节奏意味着中间经历过降级期。一段历史的第一个检查点前面没有东西，因此显示命名缺失而不是 0。
Work工作量
Difficulty over the window above. Implied hashrate is difficulty ÷ the 75 s target interval — presentation derived from two figures on this page, not a measurement: nobody here knows the real hashrate. 上方窗口内的难度走势。隐含算力 = 难度 ÷ 75 秒目标出块间隔——它是由本页面上两个数字推导出的呈现，不是测量值：这里没人知道真实算力。
Block-interval distribution over the same window. LWMA targets 75 s; the spread is ordinary PoW variance, not a fault. A backwards timestamp pair is dropped rather than shown as a bar — block timestamps are parent-clamped non-decreasing, so equal stamps are legal chain data. 同一窗口内的出块间隔分布。LWMA 的目标是 75 秒；离散是普通的 PoW 方差，不是故障。时间戳倒退的一对会被丢弃而不是画成柱子——区块时间戳只保证相对父块非递减，所以相等的时间戳是合法的链上数据。
Network网络
Peers, then mempool depth, over the observer's sampling ring. Sampled every 60 s and held in memory only, so this begins when the observer last started — it is not chain-lifetime history. 观察节点采样环内的对等节点数，以及内存池深度。每 60 秒采样一次且仅存于内存，所以它从该观察节点上次启动时开始——不是整条链的历史。
Committee委员会
Aggregates only. Per-signer participation is an operator's question and never appears on a public surface. 仅聚合值。逐签名者的参与情况属于运维问题，永不出现在公开面上。

Figures are integer bessel (1 QMB = 108 bessel), compared at zero tolerance. burned goes non-zero with name registrations: a burned fee is destroyed rather than paid to anyone, so it is the one figure with no other side of the ledger. 数字单位是整数 bessel（1 QMB = 108 bessel），零容差比对。已销毁会随名字注册变为非零：被销毁的费用是被摧毁掉的、不付给任何人，所以它是账本上唯一没有对侧的数字。

Fees are integer bessel (1 QMB = 108 bessel). spent and created are counts of notes, never amounts. 手续费单位是整数 bessel（1 QMB = 108 bessel）。花费与新建是 note 的个数，从来不是金额。
Names名字

A commit is an opaque hash and stays one — there is no name to show until its reveal, and that is the protocol rather than a gap in this feed. Fees burned are integer bessel; a burned fee is destroyed, not paid to anyone. commit 是一个不透明的哈希，而且一直是——在它被 reveal 之前没有名字可显示，这是协议如此，不是本视图缺数据。销毁的费用单位是整数 bessel；被销毁的费用是被摧毁掉的，不会付给任何人。
