place, newest first, in short sentences, with every fact, date and link
kept. Nothing else changes.

- Each record holds `disk_size`, the bytes the file takes on disk. That is its
allocated blocks, `st_blocks` × 512, from the `lstat` call the walk already
makes. `trees` prints a `disk_size` column after `size`. It is the sum over
the `dupe` copy's files. On a compressed or sparse file `disk_size` differs
from `size`. A rescan updates the `disk_size` of an unchanged file whose size
on disk changed, without reading the file (2026-10-27,

- The database keeps the number of records and the sum of their sizes in the one
row of a `totals` table. Three triggers on `files` keep that row current.
`info` reads that row. So do `scan`'s `load` phase and the `read` phases of
`report` and `trees`, for their totals. No count reads every record any more.
The triggers make each write to `files` slower. `scan` keeps SQLite's
temporary data in memory. That wins back part of that time (2026-10-27,
