status="ready" · 46 cards across 6 columns. In review holds 9 against a limit of 4, and Blocked holds 2 in a column limited to 0 — two breaches for two different reasons. Backlog has no limit at all: it is the biggest column on the board, and it stays out of headroom and overflow because a column nobody capped can neither comply nor breach.

Each rail is scaled to its own column: the track ends at that column’s limit, and anything past the line is drawn beyond it. Widths compare how full a column is, never how much it holds.

1 column has no limit set — a dashed rule rather than a rail, and is left out of every total except the board count. Not policed is not the same as compliant.

A limit of 0 is a closed column, not a missing limit: a single card in it is already a breach, which is why its line sits at the very start of the rail.

status="empty" · a valid payload carrying no columns — told apart from “loading” and from “the fetch failed”.

No columns to police

A work-in-progress limit needs at least one board column, carrying a count and either a cap or an explicit “no limit”.

status="loading" · a skeleton hero over four skeleton rows, aria-hidden with an sr-only role=status beside it. The pulse stops under prefers-reduced-motion; no timers are involved.

status="error" · the request failed. “Try again” is rendered only when onRetry is passed, and pressing it switches this card to ready.

Couldn’t load this board

The data source didn’t respond.

Every column has limit: null. 53 cards are in flight under no policy at all, so the big number is 0 and the sentence under it refuses to call that compliant — an unpoliced board is not a clean board.

4 columns have no limit set — a dashed rule rather than a rail, and are left out of every total except the board count. Not policed is not the same as compliant.

null is not 0. Intake has no limit and gets a dashed rule instead of a rail; Expedite lane is closed and empty, the only compliant state a limit of 0 has; Blocked holds 3 where zero are allowed, so its line sits at the very start of the rail and everything after it is past the line.

Each rail is scaled to its own column: the track ends at that column’s limit, and anything past the line is drawn beyond it. Widths compare how full a column is, never how much it holds.

1 column has no limit set — a dashed rule rather than a rail, and is left out of every total except the board count. Not policed is not the same as compliant.

A limit of 0 is a closed column, not a missing limit: a single card in it is already a breach, which is why its line sits at the very start of the rail.

No breach. In review sits exactly on its limit of 3 — legal, and deliberately not counted as over — so the big number stays 0 and the sentence switches to the 5 cards of headroom the board still has.

Each rail is scaled to its own column: the track ends at that column’s limit, and anything past the line is drawn beyond it. Widths compare how full a column is, never how much it holds.

Every count is 0: the board holds no work in progress, so there is no whole to take a share of and the per-column share is dropped rather than printed as a 0% that came from dividing by zero. Headroom still reads 12 cards.

order="pressure" · nine columns, long stage names, story points instead of cards. The three breaches sort to the top, then the column on its line, then the three with room; the closed-and-empty column and the unpoliced one sort last, having no verdict to rank. Long names wrap instead of being truncated away.

1 column has no limit set — a dashed rule rather than a rail, and is left out of every total except the board count. Not policed is not the same as compliant.

A limit of 0 is a closed column, not a missing limit: a single point in it is already a breach, which is why its line sits at the very start of the rail.

Ordered by pressure, not by board position.

showRails={false} · the density dial for a dashboard tile. Every verdict survives as text — over by how much, room for how many, closed, no limit set — because none of them was ever carried by the rail alone.

1 column has no limit set, and is left out of every total except the board count. Not policed is not the same as compliant.

A limit of 0 is a closed column, not a missing limit: a single card in it is already a breach.

Contract refusal: two columns share the id “review”. Every reading is keyed by id, so a duplicate would let one column's verdict quietly overwrite the other's — the component names the id instead of drawing a board that looks fine.
