…ation 171: Add ext7672-8241 stubs across 35 sklearn modules (+19,950 files) Run: https://github.com/githubnext/tsikit-learn/actions/runs/28448046366 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
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 — PR Health CheckIssue detected: Current PR status:
What I tried: I successfully merged
This appears to be an infrastructure limitation — the safeoutputs MCP server cannot access the container's local git state to generate and push the patch. Bottom line: The PR is in a healthy state (CI passing, mergeable). The only outstanding issue is that the PR is behind its base branch by 120 commits, but this does not prevent merging. A human or subsequent Evergreen run can re-attempt the merge push when the infrastructure issue is resolved.

Evergreen AnalysisCI Status: All checks are passing ✅ (Test, Lint, Build Playground) Issue: The PR branch is 120 commits behind its base branch ( Action taken: No push was made. The PR is already in a healthy state from a CI perspective and requires no code changes. The "behind base" status is an artifact of the autoloop program generating thousands of stubs in its base branch, which is not relevant to this review PR's content.
