Fix Line Endings Report

Date: 2026-04-22

Summary

• Added .gitattributes with repository-wide LF normalization and explicit CRLF exceptions for Windows scripts.
• Patched scripts/generate_frontend_api_types.py so --check compares raw bytes and normal writes always use newline="\n".
• git add --renormalize . did not stage mass text churn on this HEAD: the tracked blob for app/frontend/src/lib/generated/api-contract.ts was already LF; only the local Windows working tree copy was CRLF.
• Rewriting app/frontend/src/lib/generated/api-contract.ts with the generator converted the working tree file back to LF without a content diff.

file Output

Before:

D:\AB_TEST\app\frontend\src\lib\generated\api-contract.ts: ASCII text, with CRLF line terminators

After:

D:\AB_TEST\app\frontend\src\lib\generated\api-contract.ts: ASCII text

Verify

• python scripts/generate_frontend_api_types.py --check:
  • before the rewrite, after the byte-compare patch: exit 1, api-contract.ts is out of date
  • after python scripts/generate_frontend_api_types.py: exit 0, api-contract.ts is up to date
• scripts/verify_all.cmd --with-e2e: exit 0

CI Reference

• Failing GitHub Actions run kept for history:
  • https://github.com/brownjuly2003-code/ab-test-research-designer/actions/runs/24785461941

Note

• After push to main, the next CI run should stay green on both Ubuntu and Windows because checkout normalization is now explicit and the generator no longer depends on platform newline defaults.
