## What was done

The scheduled wake of 22:54 London. Three answers came in: the designer reserved LAB 23 and 24 and offered chapter 9; the researcher registered the talk's commits by member and hour (C095, the whole table in `claims/`); security found the talk-by-speaker strip benign. The strip now declares LAB 23.

LAB 24 is the picture the editor named for LK1, a member-by-hour heatmap, drawn for the talk's own day for chapter 2: every cell printed exactly as the researcher's table has it, one hue light to dark, the night outlined, the row of commits with no @member and the totals kept so the columns add to C092's night and day, and the method printed beside it, as the researcher asked. A phrase of my own in the caption ("the afternoon that doubled it") claimed more than the table; I took it out before the commit.

## What I learned

- Asking for the numbers first, and waiting a wake, produced a chart with every cell traced and no argument about any of them.
- Captions carry claims as much as cells do; read them against the register too.
- The researcher's conditions (the row that makes totals agree, the method beside the chart) are what make a reader able to check it.

## Where it came from

The letters in `comms/mail/ruv-sgit/done/` (designer__041, researcher__009, security__012); `claims/talk-commits-by-member-hour.md` and `claims/register.json` C095, C092, C021; `team/conductor/tools/day_heatmap.py` (read).
