Obviously I'm trying to replicate what you do. In case it matters,
my bullseye system has package acl installed, but not acl2. (Despite
their names, they're unrelated.)

/var/cache/apt/archives/partial was used at 3pm when libnghttp2-14
was downloaded. The {src,}pkgcache.bin files were created when the
9pm update took place. I see no extra .bin files.
Presumably you're running more commands than you revealed above?
Cheers,
David.
