+# Sunzi Modernization Plan
+
+## Overview
+Update Sunzi (server provisioning tool) from 2018-era dependencies to modern Ruby ecosystem.
+
+## Changes
+
+### 1. Confirm minimum Ruby versions
+Verified minimum Ruby version for `net-ssh ~> 7` and `thor ~> 1.3` is 2.6.
+Set `spec.required_ruby_version` accordingly.
+
+### 2. Update gemspec dependencies
+**File:** [sunzi.gemspec](sunzi.gemspec)
+
+| Dependency | Current | New |
+|------------|---------|-----|
+| `thor` | unrestricted | `~> 1.3` |
+| `net-ssh` | `< 5` | `~> 7.0` |
+| `rainbow` | `~> 3.0` | (keep) |
+| `hashugar` | unrestricted | (keep) |
+| `minitest` | unrestricted | `~> 6.0` |
+
+Also add:
+- `spec.required_ruby_version = '>= 2.6'`
+
+### 3. Keep YAML.load for compatibility (document trust boundary)
+**File:** [README.md](README.md)
+
+Leave `YAML.load(ERB.new(File.read('sunzi.yml')).result)` as-is for maximum compatibility.
+Add a short README note that `sunzi.yml` must be fully trusted because ERB executes Ruby
+and YAML.load can instantiate arbitrary objects.
+
+### 4. Replace Travis CI with GitHub Actions
+**Delete:** `.travis.yml`
+**Create:** `.github/workflows/test.yml`
+
+```yaml
+name: Tests
+on: [push, pull_request]
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    strategy:
+      matrix:
+        ruby: ['3.1', '3.2', '3.3']
+    steps:
+      - uses: actions/checkout@v4
+      - uses: ruby/setup-ruby@v1
+        with:
+          ruby-version: ${{ matrix.ruby }}
+          bundler-cache: true
+      - run: bundle exec rake test
+```
+
+### 5. Update README badge + requirements
+**File:** [README.md](README.md)
+
+- Replace Travis badge with GitHub Actions badge (ensure workflow name/branch match the badge URL).
+- Add a short Requirements note for the minimum supported Ruby (from step 1).
+
+### 6. Add .ruby-version
+**Create:** `.ruby-version` with content `3.2`
+
+### 7. Update template default Ruby version
+**File:** [templates/create/sunzi.yml](templates/create/sunzi.yml)
+
+Update `ruby_version: 2.5` to match the modern baseline (e.g., `3.2`).
+
+### 8. Update CHANGELOG
+**File:** [CHANGELOG.md](CHANGELOG.md)
+
+Add a `3.0.0` entry with the breaking changes (Ruby requirement, dependency bumps, CI migration).
+
+### 9. Bump version
+**File:** [sunzi.gemspec:5](sunzi.gemspec#L5)
+
+Update version from `2.1.0` to `3.0.0` (major bump due to Ruby version requirement change).
+If a version constant exists (e.g., `lib/sunzi/version.rb`), update it too.
+
+## File Summary
+| Action | File |
+|--------|------|
+| Edit | `sunzi.gemspec` |
+| Edit | `README.md` |
+| Edit | `templates/create/sunzi.yml` |
+| Edit | `CHANGELOG.md` |
+| Delete | `.travis.yml` |
+| Create | `.github/workflows/test.yml` |
+| Create | `.ruby-version` |
+
+## Verification
+1. Run `bundle install` to update Gemfile.lock
+2. Run `bundle exec rake test` to verify tests pass
+3. Run `bundle exec sunzi version` and `bundle exec sunzi create test_project` to verify CLI works
