  "prompt": "The v0.5.0 release notes state that v0.4.2 was yanked from crates.io. But the May 2026 retro and issue #89 give different dates for the yank. What date does each source give, and what is the most precise reconciliation of the timeline?",
  "gold": "The May 2026 retro (retro-may-2026.md) states 'v0.4.2 was yanked from crates.io on 2026-05-27'. Issue #89 shows @svenh asked for a yank on 2026-05-26 and @lior-bz responded 'Yanked. crates.io banner now reads: kitabi 0.4.2 yanked: ABI break, see #89.' in a comment dated 2026-05-27. The v0.5.0 release notes state 'v0.4.2 was yanked from crates.io on 2026-06-01', which contradicts both other sources. The most precise reconciliation: the yank happened on 2026-05-27 per the retro and per the issue thread timestamp; the 2026-06-01 date in the release notes appears to be an error (possibly when the release notes were drafted rather than when the yank occurred).",
