A `new file mode` hunk's pre-image is the null blob (`0000000`), so there's nothing for `--3way` to reconstruct an ancestor from — it can only add-add-conflict or hard-fail, never silently \\\"just work,\\\" when the target already has that path.

This matches the gh-aw repo's own existing `tryRecoverGitAmAddAddConflict` fallback in `create_pull_request.cjs`, which already special-cases add/add conflicts by blindly preferring \\\"theirs\\\" (the patch content) — a coarser, content-blind version of the same problem. That fallback works by luck (the agent's snapshot is usually the full intended file content) but discards any target-side change history and can't repair patches that fail before ever reaching a mergeable conflict state (e.g., `git am` erroring out at \\\"already exists in working directory\\\" rather than staging an AA conflict).\\n\\n#### Fork PR review (Tarekchehahde/gh-aw#10)\\nThe PR adds `rewriteCrossRepoCreatePatches()` / `buildCrossRepoModifyDiff()` in `git_patch_utils.cjs`, wired in from `generate_git_patch.cjs` via a new `targetTreeCwd` option (populated from `safe_outputs_handlers.cjs` when `GITHUB_REPOSITORY !== target-repo`). For each `new file mode` block it checks whether `origin/<base>:<path>` exists in the target checkout; if so, it resolves both blobs via `rev-parse`/`cat-file`, diffs them with `git diff --no-index`, and splices a proper `index <old>..<new> 100644` / `---`/`+++` header with real hunks back into the patch. This is the right shape and is unit-tested against a real `git am --3way` apply.\\n\\nTwo gaps found during review:\\n- **File mode is hardcoded to `100644`.** The rewritten header always emits `100644` regardless of the original `new file mode` value or the target blob's mode, so an executable script (`100755`) added/edited cross-repo would silently lose its exec bit after rewrite. The original `new file mode <mode>` line (already captured by the block regex) should be threaded through instead of being discarded.\\n- **Path parsing assumes no spaces/quoting.** `pathMatch` uses `/^diff --git a\\\\/(\\\\S+) b\\\\/(\\\\S+)/`, which doesn't handle git's quoted-path form (`diff --git \\\"a/foo bar\\\" \\\"b/foo bar\\\"`) that `format-patch` emits for paths containing spaces or unusual characters. This repo already has a fail-closed precedent for exactly this kind of header ambiguity in `manifest_file_helpers.cjs` (rejects unparseable `diff --git` headers rather than guessing). Today the fork's behavior on a mismatch is to leave the block untouched (falls through to the pre-existing, still-broken create-hunk path) rather than corrupt anything — so it's a completeness gap, not a correctness regression, but worth aligning with the same parser/fail-closed convention rather than a bespoke regex.\\n\\nBinary files are handled safely by omission: `git diff --no-index` on binary content produces \\\"Binary files ... differ\\\" with no `@@` hunk, `hunkStart` comes back `-1`, and the function returns `null`, falling back to the original (still-failing) create block rather than emitting a corrupt patch.\\n\\n### Recommendations\\n- Before merging the fork's approach (or an in-repo reimplementation), thread the original file mode through to the rewritten header instead of hardcoding `100644`.\\n- Reuse this repo's existing quoted/`diff --git` header parser (from `manifest_file_helpers.cjs`) rather than a new regex, so cross-repo rewriting and the existing file-protection policy checks agree on what counts as a parseable header — and so paths with spaces aren't silently skipped.\\n- Add a test case for an executable file (`new file mode 100755`) and one for a path containing a space, since neither is currently covered by the fork's `git_patch_utils.test.cjs` additions.\\n- Consider extending binary-file handling explicitly (e.g., detect and emit a proper binary-patch replace via `git diff --binary --no-index`) rather than silently falling back to the still-broken create hunk, so binary asset updates in cross-repo PRs don't regress separately.\\n\\n### Key Sources\\n- [git-apply documentation — `--3way` / `--build-fake-ancestor`]((gitscm.com/redacted)\\n- [Fork PR: Tarekchehahde/gh-aw#10 — rewrite cross-repo create patches as modify diffs](https://github.com/Tarekchehahde/gh-aw/pull/10)\\n- Related issues: #17969 (original root-cause report), #18175 (added `--3way` + Strategy 3 cross-repo fallback)\\n- In-repo precedent: `actions/setup/js/create_pull_request.cjs` (`tryRecoverGitAmAddAddConflict`), `actions/setup/js/manifest_file_helpers.cjs` (fail-closed `diff --git` header parsing)\\n\\n### Suggested Next Steps\\n1.
