Git Patch - deleted file mode Header

A deletion of an executable file, so the `deleted file mode 100755` header records the mode the file had rather than the mode to create. A patcher that writes an empty file here instead of unlinking leaves a broken executable behind.

The cutover finished in January; nothing calls this any more.

Testing contract

Expected to pass

Scenario: Apply a patch whose only change is the removal of an executable script.
Expected result: scripts/legacy-import.sh no longer exists; no zero-byte file is left in its place.

What is a .patch file?

A .patch file is a unified diff packaged for transmission, most often as produced by `git format-patch`. Beyond the diff itself it carries an email-style header with the author, date, and commit subject, a commit message body, per-file `diff --git` headers recording renames and mode changes, and hunk headers of the form `@@ -old,count +new,count @@`. Applying it reconstructs a specific change against a specific before-state.

How to use this file

Use an example .patch file to test patch application, code-review renderers, and diff parsers — exercising renames, mode changes, binary hunks, added and deleted files, and the `\ No newline at end of file` marker that naive parsers silently drop.

How to use this file for testing

“Git Patch - deleted file mode Header” is a deterministic Novus Examples fixture for Visual diff / regression, Code parsing, Editor testing. A/B image twins with controlled pixel changes, anti-alias variants, and UI chrome crops for screenshot diff and visual regression tools.

Documented properties for this file: seed 20260807 · UTF-8 · LF. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

Diff and patch fixtures name their target paths and the exact edge case they exercise — rename, mode change, binary hunk, CRLF↔LF, or missing trailing newline. Apply or render them against the documented before-state; every author, path, and hash is fictional.

Treat A/B twins as a visual regression unit: run your pixel or perceptual diff, assert a non-zero delta on the changed twin, and keep thresholds calibrated against the documented change kind in specs.
