Merge Conflict - diff3 Marker Style With Base Section
The same conflict with `merge.conflictStyle=diff3`, which inserts the merge base between the two sides behind a row of pipes. Tools that split a conflict on `=======` alone silently fold the ancestor text into the ours side.

Expected to pass- Scenario
- Parse a conflict region that contains a ||||||| base section.
- Expected result
- Three sections are recovered — ours, base ('timeout: 30'), theirs — and the base text is not attributed to either side.
What is a .txt file?
TXT is a plain-text file containing unformatted character data with no styling or structure beyond line breaks. Its interpretation depends on character encoding, most commonly UTF-8, and on line-ending convention. It is the most universal and portable text container.
How to use this file
Use an example TXT to test encoding detection, line-ending (LF versus CRLF) handling, and any tool that reads or streams raw text input.
How to use this file for testing
“Merge Conflict - diff3 Marker Style With Base Section” is a deterministic Novus Examples fixture for Error handling, Visual diff / regression, Code parsing. Deliberately corrupt and invalid files, clearly labelled, for testing how your tool fails.
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.

- diffCombined Diff - diff --cc With Two ParentsWhat `git show` prints for a merge commit: a `diff --cc` header, an index line naming three blobs, `@@@` hunk markers, and two prefix columns instead of one. The `++` line is the giveaway a reviewer is looking for — content that appears in the merge result but in neither parent.
- diffCombined Diff - Octopus Merge With Three ParentsAn octopus merge, so the hunk marker grows to `@@@@` and every line carries three prefix columns. Any parser that hard-codes `@@@` or assumes two columns reads the third column as the first character of the line's content.
- diffCombined Diff - Per-Parent mode LineWhen the file mode differs between the parents and the merge result, a combined diff adds a `mode a,b..result` line below the index line — a comma-separated shape that appears nowhere else in git's output. Parsers written for the single-parent `old mode`/`new mode` pair do not recognise it.
- txtMerge Conflict - Nested Markers From a Conflicted ResolutionSomeone committed a file that still contained conflict markers, and merging that commit produced markers inside markers. Region matchers that pair the first `<<<<<<<` with the first `=======` split this file in the wrong place and produce two overlapping regions that cannot both be resolved.
- mdMerge Conflict - Real Region Beside Marker LookalikesDocumentation about merge conflicts that quotes the markers inside a fenced code block, and then genuinely conflicts further down. A pre-commit hook that greps for `^<<<<<<<` reports two hits and blocks a clean commit; one that understands Markdown fences reports the one that matters.
- txtMerge Conflict - Three Regions in One FileOne file left with three independent unresolved regions and clean text between them, which is what a real deployment-values merge looks like. Editors that jump to 'the next conflict' and resolvers that report a boolean rather than a count both get exercised here.
