It compares the PR event's exact base and +head commits, resolves each direct shared dependency from `pyproject.toml` and +`uv.lock`, and reports every changed upstream production/other path separately from +documentation, tests and CI/configuration. Supported repositories are explicitly +allowlisted: QuantPlatformKit, UsEquityStrategies and HkEquityStrategies. + +The report uses a full Git tree diff, not a paginated GitHub compare response. +Renames are represented as old and new paths so neither side disappears. Fixed +path hints highlight authentication/token refresh, possible cloud/secret writes, +execution, risk and scheduler/automation changes. They are review prompts, not +semantic analysis, a generic dependency graph, a risk score or an allowlist. +Unmatched paths and dynamic imports remain unresolved, never presumed safe. + +## Safety and limitations + +- Report success is **not** an upgrade-safety verdict or merge approval. This adds + no auto-block/auto-approve policy and does not change existing CI gates. +- Nothing installs/imports upstream packages, invokes token refresh, reads token + contents, calls broker/cloud APIs, changes deployment, or writes secrets. +- The workflow uses `pull_request` with `contents: read`, no secrets/OIDC, no PR + comment writes, and checkout credentials are not persisted. Git fetch targets + fixed repository URLs with validated full SHAs, no shell interpolation, depth + one and per-command timeouts. No extra PAT/app grant is requested for forks or + private dependencies. Unavailable upstream access is explicitly INCOMPLETE. +- Missing pins, mismatches, failed comparisons, invalid/truncated output and report + size limits produce INCOMPLETE rather than a false clean report. The report is + advisory, so it returns zero after successfully writing that warning. Test or + infrastructure failures still fail the workflow; inspect the actual summary. +- Normal local startup wires `main.build_composer` through + `application/runtime_bootstrap_adapters.py`'s + `LongBridgeRuntimeBootstrap.build_contexts` to the injected upstream refresh + helper. Account-snapshot contexts bypass refresh. These are explicit local + review notes to revalidate when wiring changes, not generated reachability proof. +- The synthetic `350dd38ece0952beef096893a7dcf8ae3871609a` to + `155d74a615ccdebf7223787939c2dc7151d75efd` fixture includes + `src/quant_platform_kit/longbridge/auth.py` along with presentation changes so an + authentication change cannot be hidden by describing the upgrade as a facade. + +## Local use + +Python 3.11+ and Git suffice; no runtime environment or credentials are needed for +synthetic tests: + +```sh +python -m unittest discover -s tests -p test_review_shared_dependency_delta.py -v +python scripts/review_shared_dependency_delta.py \ + --base-ref FULL_BASE_COMMIT_SHA --head-ref FULL_HEAD_COMMIT_SHA \ + --output /tmp/shared-dependency-impact.md +``` + +The real comparison needs read access to those GitHub upstream trees.
