A four-state per-person day timeline that derives focus blocks from the gaps a calendar leaves, splits them into usable time and scraps at a stated minimum, and leads with the fragmentation score that falls out of the split.

status="ready" · six calendars over one 09:00–18:00 day. Hatched slabs are booked time; the accent is what survives in one piece; bare track is a gap under an hour. The board median is 51 — half the team loses more than half their free time to scraps. The card leads on Aisha Bello, the sharpest case: 6h 30m of open time in ten pieces, the longest 45m, so her fragmentation is 100 without a single meeting over 15 minutes — and her track carries no accent at all, because nothing on it clears an hour. Marcus Obeng is the counter-example at 0, with 7h 45m of focus in three blocks. Pick any row to lead the card with that person; pick it again to go back to the board.

Focus time · one day: Calendars as booked, Squad Atlas. 6 people over 09:00 to 18:00 on Thursday 12 March, Europe/Berlin. A gap counts as focus at 1 hour or longer. Across the board that is 22 hours 15 minutes of unbroken focus, 19 hours 30 minutes in meetings and 12 hours 15 minutes in gaps too short to use — 41, 36 and 23 per cent of the working time on the board. Median fragmentation is 51 out of 100 — that share of a person's free time arrives in pieces shorter than 1 hour. 2 of 6 get no unbroken 1 hour at all. Aisha Bello has 6 hours 30 minutes open in 10 pieces, none of them long enough to count as focus — the longest is 45 minutes, against 2 hours 30 minutes in 10 meetings. Fragmentation 100 out of 100. Every person is listed in the table below.

Each track is one person's 09:00–18:00. Hatched slabs are booked time, the accent is what is left over in one piece, and bare track is a gap shorter than 1h. Overlapping entries are merged and counted once, and the hairline inside a slab is where the next entry starts — so four half-hour meetings in a row still read as four. Fragmentation is the share of a person's open time that arrives in pieces under 1h: 0 means it all came in usable blocks, 100 means none of it did. A day with no open time has no fragmentation and prints a dash rather than a number. The board figure is the median of those scores by linear interpolation between closest ranks, over the people who have any open time. Shares are whole per cents apportioned by largest remainder, so the three add to exactly 100. Every time here is wall-clock on the stated day, so nothing on this card moves with a time zone or a daylight-saving change.

Lever: focusMinimumMinutes={90} on exactly the same board. Raising the bar from an hour to an hour and a half turns Dana Whitfield's one surviving 1h 15m block into a scrap — her score jumps from 72 to 100, the team goes from two people without a usable block to three, and the board median moves from 51 to 65. Nothing about the calendars changed; only what counts as focus did.

Each track is one person's 09:00–18:00. Hatched slabs are booked time, the accent is what is left over in one piece, and bare track is a gap shorter than 1h 30m. Overlapping entries are merged and counted once, and the hairline inside a slab is where the next entry starts — so four half-hour meetings in a row still read as four. Fragmentation is the share of a person's open time that arrives in pieces under 1h 30m: 0 means it all came in usable blocks, 100 means none of it did. A day with no open time has no fragmentation and prints a dash rather than a number. The board figure is the median of those scores by linear interpolation between closest ranks, over the people who have any open time. Shares are whole per cents apportioned by largest remainder, so the three add to exactly 100. Every time here is wall-clock on the stated day, so nothing on this card moves with a time zone or a daylight-saving change.
Guarded division: Rafael Duarte is booked 09:00–18:00 with no gap anywhere, so open time is zero and fragmentation would divide by it. The card prints an em dash rather than inventing 100 — a day with nothing free is a different finding from a day chopped to bits, and the share strip says so at 0 / 100 / 0. The four back-to-back entries merge into one slab, hairlined at each of the three joins.

Focus time · fully booked: Incident day, one responder. 1 person over 09:00 to 18:00 on Thursday 12 March, Europe/Berlin. A gap counts as focus at 1 hour or longer. Across the board that is 0 minutes of unbroken focus, 9 hours in meetings and 0 minutes in gaps too short to use — 0, 100 and 0 per cent of the working time on the board. Nobody has any open time, so there is no fragmentation figure to quote. 1 of 1 get no unbroken 1 hour at all. Rafael Duarte has no open time at all: 4 entries fill the whole window.

The other end of the same division: Wen Li has an empty calendar, so one 9h block spans the window and her score is a true 0 — which has to look different from the dash above. Marcus keeps a single 09:00–10:00 sync and still clears 8h in one piece.

Collisions and spill. Nadia Ferreira's 08:00–09:30 handover and 09:15–10:15 incident review genuinely overlap: they merge into one 09:00–10:15 slab, counted once, with a hairline at the seam. Her 07:00 gym misses the window and is dropped; her 17:30–19:00 deploy is trimmed at 18:00 — two trimmed, one dropped, all three stated in the footnote. Owen Marsh's first gap is exactly 60 minutes, and the minimum is inclusive, so it counts as focus rather than as a scrap.

Contract refusal: the export carries a "Focus block (no duration)" entry that starts and ends at 11:00. Dropping it quietly would glue the open time on either side of it into one long block and invent focus that never happened, so the contract refuses and names the entry, the person and the clock times.

"Focus block (no duration)" on Dana Whitfield's day ends at 11:00 but starts at 11:00. A zero-length or reversed entry would leave the open time on either side of it looking like one uninterrupted block, which is precisely the lie this chart exists to catch.
Density levers on the same board: sort="given" restores the order the data came in (Dana first, Aisha last) instead of worst-first, trackHeight={16} takes the bands down from 26px, and showShares / showFootnote drop the share strip and the method note for a dashboard tile. The headline, the axis and the accessible table are untouched.
