Two things, and the second is the reason the first is trustworthy.
.mailmap: between 2026-08-13 and 2026-08-26 this checkout carried a
`git config --local` pairing one contributor's name (Xiangzhe / @xz-dev) with
ANOTHER contributor's email (@backryun). 237 commits made here were therefore
signed with @backryun's address. The timezone split is unambiguous: @backryun's
own work commits from +0900 throughout the window and never stopped, while all
237 came from -0300, this machine. No repository file sets that address, so it
was a local config mix-up, not anything in the codebase. The local override is
now removed; the global identity was correct all along.
History is NOT rewritten: those commits live on release/v3.8.50 and
release/v3.8.51, which open PRs and other sessions build on, and the v3.8.50 tag
was cut from that line. .mailmap repairs the record for log/shortlog/blame — the
git-native answer for exactly this — without a force-push. main is unaffected:
releases squash-merge, so it carries none of the 237.
Stats: counts measured, not estimated — 1,714 commits and 248 people over
ed2db6cb19..v3.8.50, 1,666 distinct PR refs, and the 1,182 changelog entries
broken down by type. The top-25 ranking uses the consolidated identities, so
@backryun keeps their 88 real cycle commits and the misattributed 68 return to
the maintainer.
