 2. **Git Protocol:**
 
 - **STRICT PROHIBITION:** No `git commit`, `git push`, or `git tag` without using `/git-flow` or an explicit user order.
+- **BRANCHING MANDATORY:** ALL developments, features, bug fixes, and interventions MUST be done in a dedicated Git branch separated from `master`. Committing directly to the `master` branch is strictly prohibited.
 - **Conventional Commits:** Use `feat:`, `fix:`, `chore:`, `docs:`, `perf:`, `refactor:`, `style:`, `test:`, `ci:`. Breaking changes must be marked with `!` after type/scope or `BREAKING CHANGE:` in footer.
 - **Commit Validation:** Commits are automatically linted via `commitlint`. Non-compliant messages will be rejected by the pre-commit hook.
 - **History Documentation:** Use `npm run commit` to generate structured history.

+- [x] **Older Perl Compatibility**: Verified that the script runs on Perl 5.6 and 5.8 without uninitialized value warnings or syntax errors.
+- [x] **Dependency Audit**: Renovate updates for Docker actions and softprops/action-gh-release verified in CI pipelines.
+- [x] **Idiomatic Boolean Refactoring**: Completed project-wide refactoring to use standard Perl Boolean practices (truthiness checks).
+  - Replaced `eq '0'`, `ne '0'`, `eq 0`, `ne 0`, `eq ""`, `ne ""` with truthy/falsy evaluations where appropriate.
+  - Refactored `%CLI_METADATA` defaults from `'0'` to `undef` for string/path options.
+  - Wrapped template reading logic in `get_template_model` to prevent `uninitialized value` warnings during `require`.
+  - Verified 100% test stability (262 tests passed).
