Hi,

not much work done this month. The numbers still look decent.
There are some extra build failures from an experiment,
that can be ignored as it does not matter for our production use.

Here are the autogenerated bits:
last month's status:
https://lists.opensuse.org/archives/list/factory@lists.opensuse.org/thread/ZYTBSM2FG6OK2XL6KCBXHIVFTWOUB524/

Last months' reproducible builds project updates (including my work):
https://reproducible-builds.org/reports/2025-11/

I uploaded https://rb.zq1.de/compare.factory-20251231/ today

https://rb.zq1.de/spec/glossar.txt explains the meaning of below values:
total-packages: 16206 (+23)
build-tried: 16137 (+26)
build-failed: 133 (+82)
build-n-a: 190 (+28)
build-succeeded: 15814 (-84)
build-official-failed+na: 23 (-23)
build-compare-failed: 155 (+5)
build-compare-succeeded: 15659 (-89)
verify-failed: 678 (+42)
verified-semi-reproducible: 15193 (-11)
verified-bit-identical: 15003 (-5)
bit-by-bit-identical: 15644 (-62)

https://rb.zq1.de/compare.factory-20251231/graph.png
shows the change over time

https://rb.zq1.de/compare.factory-20251231/unreproduciblerings.txt
lists very unreproducible core packages (bootstrap+DVD)

Of the badly unreproducible packages,
1 were in ring0
20 were in ring1

That makes it 21/4043 => 0.52 %
which is below the overall average of
155/15814 => 0.98 %

187/15814 => 1.18 % of packages are not perfectly reproducible
