Commits on May 2, 2026 v0.42.0: eval-suite plumbing through ref-mode merge rebuild The reference-mode merge rebuild path now propagates the user's eval suite, pipeline, and metric-retirement decisions onto the mirrored merge commit instead of leaving them as the empty placeholders sync_one_commit originally planted. Ten previously ignored acceptance specs unblock as a consequence. Added ----- - `morph_core::rebuild_merge_commit` + `MergeRebuildOpts`. After `sync_to_head_with_origin` mirrors the merge commit, the rebuild helper re-derives the commit using the MergePlan's auto-union eval suite, the user's --pipeline / --eval-suite / --metrics, and any retired metrics, then re-points the branch ref onto the rewritten hash. Same recipe the non-merge `morph commit` rewrite already used. - `MERGE_REF.json` now carries pipeline / eval_suite / retired_metrics / retire_reason across the conflict boundary so `morph merge --continue` reproduces the same plan a single-shot merge would have used.…
