The card "Let customers report a claim without calling us" reaches two backlog
levels. The card itself shows the one number that matters at a glance,
**3/10**, and the breakdown behind it answers per level, in full words:
**Features 0/3** and **Backlog items 3/10**. The next question is always which
three, and which ten. The rollup on the card is a button that answers it, and
so is the count on each linked item's row behind the link chip.

## Steps

1. On the card, select the rollup at the end of the chip row, the ring, the
   bar and the total after the link chip; its tooltip opens with **Rollup
   breakdown across 2 linked items** (just **Rollup breakdown** when a single
   item is linked). Where the linked work carries estimates, a second sentence
   follows it, *Effort at Backlog items: 13 of 40 done, 2 without a value.* The
   flyout opens below it, or above when there is too little room below and
   more room above.
2. Read the strip under the title: **Features 0/3**, then **Backlog items
   3/10**, top level first, one per backlog level that has judged items,
   whichever linked item they sit under. The card itself shows only the
   total, so this strip is where the per-level numbers appear. A linked item
   the total leaves out still has its entry here: an undecomposed Feature
   beside one with backlog items reads **Features 0/1**, and the rollup's
   tooltip says *One linked item has no Backlog items to add, so this count
   leaves it out*. [What the rollup counts](https://anykanban.com/docs/concepts/what-the-rollup-counts/)
   says why. After the counts comes the sum of the estimates, as an
   entry of its own naming its level, **Effort at Backlog items: 13/40?, 2
   without a value**, and each linked item's heading carries its own `Σ`.
3. Leave **Undone** selected, which is the default. The hierarchy is drawn parent
   before children, indented by depth, trimmed to what is still open: the
   seven backlog items not yet done, under the features that hold them. Every
   row carries its work item type's icon, so a feature is told from the
   backlog item beneath it without counting indents.
4. Select **All**. The same hierarchy, now complete: the three finished items
   join the list with a green dot, and anything excluded from the count is
   dimmed with the reason written on its row.
5. When everything is finished, **Undone** has nothing to list and says so,
   with *"Nothing is left undone"*, rather than showing a heading per linked item
   with no rows beneath it. Select **All** to see the whole tree.
6. Select any title to open that item in the native work item form. To close
   the flyout, select the same rollup again, which toggles it, or press Escape,
   or select anywhere outside it. All three return focus to the control you
   opened it from.
7. To scope the answer to one link, open the **link chip** and select the count
   on a single row instead of the rollup.

## What you should see

The list and the number cannot disagree, because both are read from the same
judged data. Items left out of the count are dimmed and carry the reason as text on the
row: **Removed (not counted)**, **Another project (not counted)**, **Unknown
state (not counted)**, or **Unavailable (not counted)**. **Undone** answers
"what is left"; **All** answers "what was counted", finished work included.
Rows at the level the estimates are summed at print their value after the
state, or *no value*. Rows on other levels print nothing more, and neither do
rows from a project whose process maps no effort field. See [What the rollup
counts](https://anykanban.com/docs/concepts/what-the-rollup-counts/) for what the sum adds up.

## Notes

A count ending in **+**, as in "8/22+", is a lower bound: the descendant tree hit a
size cap, or items it promised could not be read. The flyout then ends with a
note saying so and the board carries a warning. Deliberate exclusions never
produce a **+**; they are reported as dimmed rows instead.

A linked item with nothing beneath it appears once, as its own heading with
its ratio. There is no separate row under it, because the heading already IS
that item.

Per-row counts need not add up to the header count. The card counts each distinct
work item once, even when two linked items share a subtree, while every row keeps
its own full truth, so a row can legitimately read higher than the card.
