Every file the walk records now gets three hashes: head and tail, of
its first and last 64 KiB, and content. The content hash covers the
whole file under 100 MiB, and 1 MiB at each gigabyte from 100 MiB up,
so a large file is never read in full. One 100 MiB constant replaces
the 10 MiB and 50 MiB thresholds. The size census, the records stored
without hashes and the content phase are gone, so a rescan reads only
new and changed files. report and trees no longer special-case a
missing content hash. README "Duplicate detection" and "Rationale" are
rewritten.
Judgement call: info drops its two hash-count lines, which now always
equal the record count.
Model: opus-5-5
info prints the database's path and source, the sizes of the database
file and its -wal file, when the database file last changed, the schema
version and the record counts, one per line as a name, a tab and the
value. It opens the database as report does and shows an open and a
count phase on stderr. The schema version and the counts come from one
read-only transaction, the counts from one query.
seedDatabase now closes test databases out of WAL mode, as scan does;
otherwise info's own connection creates an empty -wal file. The open
phase's name and text became constants for the linter, and the scan
command moved to newScanCommand to keep newRootCommand short enough.
Judgement call: the lines are written after the last display ends, so they skip the display's stdout writer.
