WalkthroughThe CLI supports explicit two-dot and three-dot Git comparisons. It resolves immutable commits or merge bases, preserves pathspecs, records object identities, validates operands, and documents the supported forms. ChangesCommit-range analysis
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to The PR adds canonical commit-range artifact behavior and reports passing tests and validation checks; no actionable merge-blocking risk remains beyond normal review. Sequence Diagram(s)sequenceDiagram

In `@diffgraph/cli.py`:
- Around line 379-381: Update terminal-flag parsing in _terminal_options so
literal pathspecs after the -- boundary, including --compact and --all, are
preserved. Only recognize terminal flags before the pathspec boundary, keeping
_pathspecs_after_diff_separator(raw_args) consistent with diff_args and
preventing _structural_scope from raising the pathspec-scope error.
- Around line 178-188: Update _range_operand to reject operands containing four
or more consecutive dots before selecting or splitting the two- or three-dot
separator, raising the existing click.UsageError for malformed ranges while
preserving valid BASE..HEAD and BASE...HEAD handling.
