Known Limitations + +### `--changed-files` Compares to origin/main Only + +The script's `--changed-files` mode always compares against `origin/main` or `origin/master`, not against `github.base_ref`. + +**Impact**: For PRs targeting `develop`, if `develop` diverges significantly from `main`, the changed file detection may not be accurate. + +**Example**: If a developer creates branch `feature/my-change` from `main` at commit `abc123`, then `main` advances to commit `def456`, the `--changed-files` mode will compare against `origin/main` (at `def456`), not the original branch point (`abc123`). This means: +- Files changed in `main` after branching may appear as "unchanged" in the diff +- Files that were the same at branch point but diverged in `main` may show as "changed" + +In practice, this typically results in checking *more* files than strictly necessary (files touched by both the PR and recent main commits), which is a safe failure mode. The risk scenario is if a violation was introduced in `main` after branching and the PR happens to touch the same file - the violation would be detected, but attributed to the PR. + +**Accepted for now**: The common case is PRs to `main`, and `develop` should be relatively close to `main`. A `--base-ref` argument can be added when this actually causes problems. + +### Process Requirements (Not Enforced by CI) + +The following mitigations are documentation-only and rely on code review discipline: + +1. **Config changes**: When modifying `scripts/check_transport_imports.py` or its banned modules list, manually verify all existing files +2. **Allowlist removals**: When removing a file from `TEMPORARY_ALLOWLIST`, include the actual fix in the same PR + +**Future enhancement**: Add path-based CI conditions to enforce these rules automatically. + +--- + +## 6.
