+# PR #16114: Workflow Design Impact Analysis
+
+## Affected Workflows
+- lint-development: The PR modifies the implementation of the `map-unwrap-or` lint in `clippy_lints/src/methods/map_unwrap_or.rs`, which is the core library housing all lint implementations, and updates the corresponding UI test in `tests/ui/map_unwrap_or.stderr`. These files are explicitly listed in the relevant_files for this workflow.
+
+- testing: The PR updates the expected output file for the `map-unwrap-or` UI test in `tests/ui/map_unwrap_or.stderr`, which is part of the UI test infrastructure managed by `tests/compile-test.rs`. This matches the relevant_files ["tests/", "ui/"] for this workflow.
+
+## lint-development Analysis
+### Summary of design changes
+The PR changes the logic in an existing lint implementation to allow multiline suggestions in diagnostics, which is part of "implementing the analysis logic using compiler APIs" (line 87 in design doc). This does not add new steps, modify components, or change interactions in the scaffolding or integration/execution sequence diagrams. The high-level workflow for developing and integrating lints remains unchanged; only the specific lint's behavior is enhanced for better user experience, potentially benefiting lint development by providing more informative suggestions during testing. No mermaid diagrams need updates.
+
+## testing Analysis
+### Summary of design changes
+The PR updates the expected output (`.stderr`) for a UI test, which falls under "Blessing and Maintenance" where `cargo bless` or `--bless` updates expected test outputs after changes (line 96 in design doc). This is a routine step when lint behavior changes, such as new or modified diagnostics. It does not affect the UI tests sequence diagram or dogfooding sequence; the workflow for executing and validating tests via `cargo test` remains the same. The benefit is ensuring test correctness with the updated multiline suggestion output. No mermaid diagrams need updates.
