+**Testability-run specifics** (guided mode invoked by autodev existing-code flow Step 4):
+- Run name is `01-testability-refactoring`.
+- Phase 3 (Safety Net) is skipped by design — no tests exist yet. Compensating control: the `list-of-changes.md` gate in Phase 1 must be reviewed and approved by the user before Phase 4 runs.
+- Scope is MINIMAL and surgical; reject change entries that drift into full refactor territory (see existing-code flow Step 4 for allowed/disallowed lists). Flagged entries go to `RUN_DIR/deferred_to_refactor.md` for Step 8 (optional full refactor) consideration.
+- After Phase 4 (Execution) completes, write `RUN_DIR/testability_changes_summary.md` as Phase 4.5. Format: one bullet per applied change.
+  ```markdown
+  # Testability Changes Summary ({{run_name}})
+
+  Applied {{N}} change(s):
+
+  - **{{change_id}}** — changed {{symbol}} in `{{file}}`: {{plain-language reason}}. Risk: {{low|medium|high}}.
+  ```
+  Group bullets by category (config extraction, DI insertion, singleton wrapping, interface extraction, function split). Present the summary to the user via the Choose format before proceeding to Phase 5.
+
 At the start of execution, create a TodoWrite with all applicable phases.
