Odd One Out <mv-odd-one-out>
在一组本应相同的条目中自动发现异常值：服务器、容器或环境之间的配置漂移，同一商品各变体之间的价格和库存不一致，某个员工的权限与同岗位同事不同，某个区域的设置出现偏差。
文化出处
芝麻街，Children's Television Workshop（Joan Ganz Cooney 和 Lloyd Morrisett）（1969 年，剧集）。在一个固定环节中，四样东西并排展示，观众要在答案揭晓前找出与其他不同的那一个。在界面中，一组本应相同的项目会逐字段与其自身的多数值比较，打破规律的值会被原地指出、计数并解释，同时提供让它们恢复一致的方法。
工作原理
自动找出一组本应相同的项目中的异常值：服务器、容器或环境之间的配置漂移，同一商品各变体之间的价格和库存不一致，某位员工的权限与同一角色的同事不同，某个区域的设置与其他区域有出入。可以包裹你自己的卡片或表格行（项目带 data-item，值带 data-field="key"），也可以传入 items 数组，由它渲染成表格（每行或每列一个项目）或卡片。对每个字段，它会找出多数值（精确匹配、不区分大小写和重音，或使用你自己的 normalize 或 comparator），数字则使用中位数加稳健的 MAD 检验或绝对值 / % 容差，并原地标出突出的值：一个圆环、一个着色单元格和一个徽标，徽标的符号说明差异类型（≠ 不同，▲ 偏高，▼ 偏低，∅ 缺失，+ 仅此处有），并附 “differs from 7 of 8”。每个项目都各不相同的字段（主机名、IP）不做处理，没有明确多数值的字段单独列出，缺少大多数其他项目都有的字段的项目也会被标记。摘要列出每个异常项目（“web-04 differs on 3 fields: TLS min version, Max body size, Region”），将异常值与多数值并列显示，并提供跳转链接、在异常之间切换的 N / P 导航，以及可选的逐值 “Align” 操作，该操作经由可取消的 mv-align 事件，由应用执行修正；“Differences only” 开关会淡化所有一致的内容（渲染出的视图还会折叠一致的字段）。当标记、输入或数据变化时会实时重新检查，并以礼貌方式播报。

When to use
- A fleet of servers, containers or feature-flag environments must share one configuration and drift has to jump out
- A product's variants (sizes, colors, bundles) should share price, weight or tax codes except for the one mistyped
- An access review compares people in the same role and must surface the one with an extra or missing permission
- A small set of regions, stores or tenants should be configured alike and a reviewer wants the exceptions first
Avoid when
- Two or three documents of different kinds must be reconciled field by field against a reference, with a verdict → use Cross-Check instead
- Several sources describe the same event over time and the disagreements are about what happened when → use Accounts instead
- Thousands of records are involved: compute outliers server-side and show them in a paginated table → use Data table instead

用法
快速开始，最小可运行标记：
<mv-odd-one-out item-key="host">
<p data-item="web-01"><b data-field="host">web-01</b> <span data-field="tls">TLS 1.3</span></p>
<p data-item="web-02"><b data-field="host">web-02</b> <span data-field="tls">TLS 1.2</span></p>
<p data-item="web-03"><b data-field="host">web-03</b> <span data-field="tls">TLS 1.3</span></p>
</mv-odd-one-out>标准标记，可在此基础上通过属性、data-* 和 CSS 变量进行定制：

</div>API
Attributes
| Name | 类型 | Default | Description |
|---|---|---|---|
item-key | string (field key) | Field that names each item (host, sku, email). It is used as the item label and never compared. In data mode it is also the id property (default "id", then "name"). | |
compare | auto | exact | fold | number | number:<tol> | number:<tol>% | ignore | auto | Default rule for fields without their own (data-compare on a header or a field, or compare in the fields property). auto treats a field as numeric when every value parses as a number with the same prefix and unit ($, ms, GB), otherwise exact. exact compares trimmed text with collapsed spaces; fold ignores case and accents; number without tolerance flags robust outliers (modified z-score over the median absolute deviation, or any value off the common one when most items are identical); number:0.5 or number:5% flags values farther than that from the median; ignore never compares. Set exact on numeric-looking codes (HS codes, ZIPs, versions you do not want ranked) so they are reported as ≠ rather than ▲ / ▼. |
sensitivity | number | 3.5 | Modified z-score above which a numeric value is an outlier (Iglewicz and Hoaglin's 3.5). Lower flags more. |
quorum | number (0..1) | 0.5 | Share of items the majority must exceed. Below it the field has no clear majority: nothing is marked in place and the field is listed under “No clear majority”. A field where every item differs (hostnames, IPs) is treated as naturally unique and left alone. |
min-items | number | 3 | Fewest items needed to speak of a majority. With fewer, the summary says so and nothing is marked. |
differences-only | boolean | Dims every agreeing value (and agreeing items further) so the odd ones pop; rendered views also hide fields where every item agrees. Reflected by the summary's switch. | |
alignable | boolean | Adds an “Align” button to each odd value in the summary. It emits mv-align (cancelable); see the event for the default action. | |
summary | top | bottom | none | top | Where the summary panel goes, or none to only mark values in place (events, navigation methods and announcements still work). |
badges | auto | full | compact | none | auto | In-place badge text: full (“differs from 7 of 8”), compact (“7/8”, full text in the tooltip and for screen readers) or none (ring only). auto is compact inside table cells, full elsewhere. |
layout | rows | columns | cards | rows | Data mode only: a table with one item per row, a table with one item per column (best for many fields and few items, like environments or people), or a grid of cards. |
label | string | Consistency check | Accessible name of the rendered table and its scroll region. |
data-item | string (on an item) | Marks an item (card, row, section) and gives its id. Without any, direct children containing [data-field] are the items. data-item-label or a [data-item-title] child gives a nicer label. | |
data-field | string (on a value) | Key of a value inside an item. The value is data-value when present, the value of an input / select / textarea (checked state for checkboxes), otherwise the text (the component's own badges are skipped). An element with data-field outside any item is the field's header: its text is the field label and it receives an odd-count pill. | |
data-compare / data-field-label | string (on a header or value) | Per-field rule (same syntax as compare) and label. | |
data-odd-one-out / -kind / -item / -current / -count | set by the component | On values: odd | agree | split | neutral, and the kind (differs, higher, lower, missing, extra). On items: odd | agree. data-odd-one-out-current on the oddity being visited; data-odd-one-out-count on headers. The host gets data-state="odd | clear | few". |
Properties
| Name | 类型 | Description |
|---|---|---|
items | object[] | null | Data mode: one object per item; the component renders the view set by layout. null (default) reads the markup. Objects are copied; align changes the copies. |
fields | (string | { key, label?, compare?, format?, normalize? })[] | { [key]: { … } } | Field order, labels and rules. compare also accepts a function (a, b) => boolean; normalize(value) returns the text actually compared; format(value) the text displayed (data mode). Applies to markup mode too (labels and rules). |
oddities | object[] | Read-only: { id, item, itemLabel, element, field, fieldLabel, fieldElement, value, majority, agree, total, kind, basis ("majority" or "median"), badge, description } in item then field order. |
splits | { field, label, groups: { value, count }[] }[] | Read-only: fields without a clear majority. |
report | { field, label, status, majority, agree, total, rule }[] | Read-only verdict per field; status is agree, odd, split, unique, ignored or skipped. |
strings | object | Every visible and announced text (en-US by default), merged with the defaults. Plural entries are [one, other] arrays. |
Methods
| Name | Description |
|---|---|
next() / previous() | Moves to the next or previous oddity (wrapping): focuses it, scrolls it into view, marks it current and announces it. Returns false when there is none. |
focusOddity(index) | Visits a given oddity. |
align(item, field) | Same as the Align button: emits mv-align and applies the default action unless canceled. Returns true if not canceled. |
refresh() | Re-checks now (changes are otherwise picked up automatically, debounced). |
Events
| Name | Description |
|---|---|
mv-oddities | After the first check and whenever the oddities change. detail: { list (as the oddities property), items (odd item ids), fields (odd field keys), splits, count, total }. |
mv-align | Align was requested for an odd value. Cancelable. detail: { item, itemLabel, field, fieldLabel, value, majority (the target value; null for kind "extra", meaning remove), kind, element, fieldElement, data (the item object in data mode) }. Default action: data mode updates the item's copy and re-renders; markup mode sets the value of an input / select / textarea (firing input and change) or the element's text and data-value. Call preventDefault() to apply it yourself (framework state, API call); the component re-checks when your DOM or data changes. |
Content structure
| Name | Description |
|---|---|
(content) | Your items: a table with data-item rows, a grid of cards, sections… Never moved or rebuilt; the component only adds data-odd-one-out-* attributes, tabindex="-1" on a visited value, and small badges marked .mv-odd-one-out-own. |
CSS classes
| Name | Description |
|---|---|
mv-odd-one-out-summary | Summary panel (title, Differences only switch, previous / next, list of odd items, No clear majority line); data-state="odd | clear | few". |
mv-odd-one-out-badge | In-place badge appended inside an odd value (after it for inputs); data-kind; holds the glyph, the visible count and a screen-reader description. |
mv-odd-one-out-count | Odd-count pill appended to a field header. |
mv-odd-one-out-view / -table / -cards / -card | Views rendered in data mode. |
mv-odd-one-out-own | Every node the component creates; ignored when values are read. |
CSS variables
| Name | Default | Description |
|---|---|---|
--mv-odd-one-out-color | var(--mv-warning) | Tint of odd values, badges and item edges. |
--mv-odd-one-out-ink | color-mix(color, --mv-fg 48%) | Text color on odd tints (kept readable in light and dark). |
--mv-odd-one-out-agree-color | var(--mv-success) | Icon tint when everything agrees. |
--mv-odd-one-out-dim | 0.4 | Opacity of agreeing values under Differences only. |
--mv-odd-one-out-list-height | 22rem | Max height of the summary list before it scrolls. |
Accessibility
Color is never the only signal: every odd value gets a ring and a badge whose glyph encodes the kind (≠ differs, ▲ higher, ▼ lower, ∅ missing, + only here), and the badge carries a screen-reader description read with the value itself (“TLS 1.2. Differs from 7 of 8: TLS 1.2, majority TLS 1.3.”); for inputs the description is linked with aria-describedby instead. Field headers get an odd-count pill with a spoken equivalent. The summary is a labelled section whose heading states the result; odd items are a real list, each with a button jumping to the item and one per odd value whose accessible name includes the full description, plus labelled Align buttons (“Align TLS min version on web-04 to TLS 1.3”). N and P move to the next and previous oddity anywhere inside the component (ignored while typing in a text field or with modifiers; buttons with aria-keyshortcuts do the same): the value is focused (tabindex="-1" is added only while it is odd), scrolled into view, marked current with a thicker ring and announced (“Oddity 2 of 5: web-04, Region. Differs from 7 of 8…”). Changes after the first check are announced once in a polite live region with the new summary, and focus stays on the equivalent summary control after a re-render. The Differences only switch is a native checkbox with role="switch". The rendered table has real th headers with scope and a focusable, labelled scroll region. Reduced motion (prefers-reduced-motion or data-motion="reduce"): the one-shot highlight pulse and badge nudge are removed and scrolling is instant. Forced colors: odd values are outlined with the Mark system color and the current one with Highlight.
