feat(provenance): retain requested range refs by nia-sg-bot · Pull Request #52 · WildestAI/DiffGraph-CLI

nia-sg-bot · 2026-09-10T15:35:31Z

Summary

retain the user-requested base/head refs alongside immutable resolved range endpoints
record explicit two_dot or three_dot comparison semantics in diff_ref
validate the expanded provenance contract through CLI and schema-backed tests

Part of #21

Validation

python3 -m pytest tests/test_structural.py tests/test_contract.py tests/test_git_snapshot.py -q
python3 -m pytest -q
python3 -m diffgraph.cli --structural-json - diff HEAD~1..HEAD
git diff --check

Compatibility

This is additive schema-v2 provenance. Existing base_ref and head_ref retain immutable resolved endpoint semantics; consumers that need display intent can use the new optional fields.

Summary by CodeRabbit

New Features
- Diff artifacts now include the originally requested base and head references.
- Commit-range comparisons identify whether two-dot or three-dot semantics were used.
- Artifacts continue to record immutable resolved comparison endpoints and file-level identities.
Bug Fixes
- Working-tree comparisons no longer report commit-range comparison modes.
Documentation
- Updated documentation and schema descriptions to clarify requested versus resolved references.

Walkthrough

The diff artifact now records user-requested refs, resolved immutable comparison endpoints, and comparison mode. Worktree comparisons leave comparison mode null. The schema, structural analysis, tests, and README describe or validate these fields.

Changes

Diff reference metadata

Layer / File(s)	Summary
Diff reference contract and population `diffgraph/schema/diffgraph-v2.schema.json`, `diffgraph/structural.py`	The schema defines nullable requested refs and `comparison_mode`. Structural analysis emits `two_dot` or `three_dot` only for commit ranges and keeps resolved endpoints immutable.
Diff reference validation and documentation `tests/test_structural.py`, `README.md`	Tests validate null worktree metadata and requested refs for two-dot and three-dot ranges. The README documents requested refs, resolved endpoints, comparison mode, and blob identities.

Inline comments:
In `@diffgraph/schema/diffgraph-v2.schema.json`:
- Line 48: Update the base_ref description in the schema to define it as the
resolved comparison base object ID, including the resolved merge base for
three_dot ranges, rather than the requested commit SHA or ref. Keep requested
input semantics documented only by requested_base_ref, and leave unrelated
schema descriptions unchanged.

In `@diffgraph/structural.py`:
- Line 928: Update the comparison_mode assignment in analyze_local_diff so it is
populated only when a commit range is supplied; unstaged or staged working-tree
comparisons without base_ref and head_ref must leave it null even when
three_dot=True. Add regression coverage for both unstaged and staged calls, or
reject three_dot when no commit range is provided.
