Evergreen — Merge AttemptEvergreen attempted to bring this PR up to date with its base branch ( The local merge completed cleanly, but the resulting patch contains ~519,000 file changes — far exceeding the capacity of the automated push tooling. A manual To fix manually: git fetch origin autoloop/build-tsikit-learn-scikit-learn-typescript-migration
git checkout autoloop/build-tsikit-learn-scikit-learn-typescript-migration-review-1782826745383
git merge origin/autoloop/build-tsikit-learn-scikit-learn-typescript-migration --no-edit
git push origin autoloop/build-tsikit-learn-scikit-learn-typescript-migration-review-1782826745383The failing CI checks (Lint, Test, Build Playground) may also be resolved once the branch is up to date with the fixes applied in the base branch.

Evergreen: Attempted to merge base branch into this PR to resolve the The merge itself completed cleanly (no conflicts), but the resulting diff contains 917,700 file changes — almost entirely auto-generated stub files added by the Autoloop base branch over 120 iterations. The patch-based push tool cannot handle a diff of that size.

Evergreen: Unable to merge base branch (patch too large)Evergreen attempted to bring this review branch up to date with its base branch ( What happenedThe base branch has accumulated ~122 iterations of stub files (~19,950 files per iteration), making the cumulative diff approximately 358 MB. This exceeds the push tool's 100 MB buffer limit, causing the merge commit to fail to apply. Why this can't be fixed automaticallyThe RecommendationThis PR may need to be closed and re-opened from the current base branch tip, or a human with direct push access could force-update the branch. The underlying autoloop program continues to progress on the base branch regardless.
