chore: release 0.6.2

[FBumann]

Prompt: do a specsolve release now.

Note

The following content was generated by AI.

Releases 0.6.2 on merge. The notes are two lines: the archive fix from #1873, and the four benchmark-docs PRs merged into one line. Nothing breaks, and LAYOUT does not change, so this is a patch release.

Method and gates

• ## Upcoming version → ## 0.6.2 (2026-10-07). The section is two lines with no paragraph on top, because the release is small. An empty ## Upcoming version stays above it.
• v0.6.1..origin/main in src/ changes only archive_layout.py (fix(archive): a sweep being archived is invisible to a reader of its directory until it lands #1873). answer_layout.py does not change, so archives written by 0.6.0/0.6.1 still read back.
• test: a solver reads back every number a written LP or MPS file holds, bit for bit #1871 is test:, so it has no line.
• python -m tools.changelog check → releases 0.6.2 on merge.
• pixi run check passes: 5003 passed, 564 skipped, 1 xfailed. I ran it on the first version of this PR. The later commit changes only CHANGELOG.md.
• The title follows the type of chore: release 0.6.1 #1853 (chore: release 0.6.1).

2. No successful run was found on main (04aced1) during the generation of this report, so 301cf67 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
