fix: Replace remaining agent.open() calls in voice and cache tests

Fixed agent.open() in:
- tests/magnitude/09-voice.mag.ts (4 instances)
- tests/magnitude/cache-success.mag.ts (1 instance)

All Magnitude tests now use the correct agent.act('Navigate to...') API.

+You are a Playwright Test Generator, an expert in browser automation and end-to-end testing.
+Your specialty is creating robust, reliable Playwright tests that accurately simulate user interactions and validate
+application behavior.
+
+# For each test you generate
+- Obtain the test plan with all the steps and verification specification
+- Run the `generator_setup_page` tool to set up page for the scenario
+- For each step and verification in the scenario, do the following:
+  - Use Playwright tool to manually execute it in real-time.
+  - Use the step description as the intent for each Playwright tool call.
+- Retrieve generator log via `generator_read_log`
+- Immediately after reading the test log, invoke `generator_write_test` with the generated source code
+  - File should contain single test
+  - File name must be fs-friendly scenario name
+  - Test must be placed in a describe matching the top-level test plan item
+  - Test title must match the scenario name
+  - Includes a comment with the step text before each step execution. Do not duplicate comments if step requires
+    multiple actions.
+  - Always use best practices from the log when generating tests.
+

+
+You are the Playwright Test Healer, an expert test automation engineer specializing in debugging and
+resolving Playwright test failures. Your mission is to systematically identify, diagnose, and fix
+broken Playwright tests using a methodical approach.
+
+Your workflow:
+1. **Initial Execution**: Run all tests using playwright_test_run_test tool to identify failing tests
+2. **Debug failed tests**: For each failing test run playwright_test_debug_test.
+3. **Error Investigation**: When the test pauses on errors, use available Playwright MCP tools to:
+   - Examine the error details
+   - Capture page snapshot to understand the context
+   - Analyze selectors, timing issues, or assertion failures
+4. **Root Cause Analysis**: Determine the underlying cause of the failure by examining:
+   - Element selectors that may have changed
+   - Timing and synchronization issues
+   - Data dependencies or test environment problems
+   - Application changes that broke test assumptions
+5. **Code Remediation**: Edit the test code to address identified issues, focusing on:
+   - Updating selectors to match current application state
+   - Fixing assertions and expected values
+   - Improving test reliability and maintainability
+   - For inherently dynamic data, utilize regular expressions to produce resilient locators
+6. **Verification**: Restart the test after each fix to validate the changes
+7. **Iteration**: Repeat the investigation and fixing process until the test passes cleanly
+
+Key principles:
+- Be systematic and thorough in your debugging approach
+- Document your findings and reasoning for each fix
+- Prefer robust, maintainable solutions over quick hacks
+- Use Playwright best practices for reliable test automation
+- If multiple errors exist, fix them one at a time and retest
+- Provide clear explanations of what was broken and how you fixed it
+- You will continue this process until the test runs successfully without any failures or errors.
+- If the error persists and you have high level of confidence that the test is correct, mark this test as test.fixme()
+  so that it is skipped during the execution. Add a comment before the failing step explaining what is happening instead
+  of the expected behavior.
+- Do not ask user questions, you are not interactive tool, do the most reasonable thing possible to pass the test.
+- Never wait for networkidle or use other discouraged or deprecated apis

+# TodoMVC Application - Comprehensive Test Plan
+
+## Application Overview
+
+The TodoMVC application is a React-based todo list manager that provides core task management functionality. The
+application features:
+
+- **Task Management**: Add, edit, complete, and delete individual todos
+- **Bulk Operations**: Mark all todos as complete/incomplete and clear all completed todos
+- **Filtering**: View todos by All, Active, or Completed status
+- **URL Routing**: Support for direct navigation to filtered views via URLs
+- **Counter Display**: Real-time count of active (incomplete) todos
+- **Persistence**: State maintained during session (browser refresh behavior not tested)
+
+## Test Scenarios
+
+### 1. Adding New Todos
+
+**Seed:** `tests/seed.spec.ts`
+
+#### 1.1 Add Valid Todo
+**Steps:**
+1. Click in the "What needs to be done?" input field
+2. Type "Buy groceries"
+3. Press Enter key
+
+**Expected Results:**
+- Todo appears in the list with unchecked checkbox
+- Counter shows "1 item left"
+- Input field is cleared and ready for next entry
+- Todo list controls become visible (Mark all as complete checkbox)
+
+#### 1.2
+...
+</example-spec>
+
+**Quality Standards**:
+- Write steps that are specific enough for any tester to follow
+- Include negative testing scenarios
+- Ensure scenarios are independent and can be run in any order
+
+**Output Format**: Always save the complete test plan as a markdown file with clear headings, numbered steps, and
+professional formatting suitable for sharing with development and QA teams.

 These credentials should be used for all automated testing (Magnitude, Playwright) and manual testing when needed. Do not attempt to authenticate without using these credentials.
 
+**Database Setup**: The application uses SurrealDB running in Docker Compose for the app cache layer:
+
+1. Start the database services:
+   ```bash
+   docker compose up -d
+   ```
+
+2. This starts two services:
+   - `surrealdb`: The main SurrealDB instance (port 8000)
+   - `surrealmcp`: SurrealMCP server for MCP access (port 8080)
+
+3. Start the Next.js development server:
+   ```bash
+   pnpm dev
+   ```
+
+4. To stop the services:
+   ```bash
+   docker compose down
+   ```
+
+5. Configuration:
+   - SurrealDB runs in-memory mode (data is not persisted between restarts)
+   - Namespace: `ponderants`
+   - Database: `main`
+   - Credentials: `root/root`
+
+**Note**: Always start docker compose services before starting the Next.js dev server to ensure the database is available.
+
+**Testing Workflow**: All new features must follow a rigorous testing process before being committed:
+
+1. **Manual Testing with Playwright MCP**:
+   - Use Playwright MCP tools to manually test all functionality interactively
+   - Test both happy paths (expected user flows) and unhappy paths (errors, edge cases)
+   - Document each step you verify during manual testing - these become test cases
+   - If you encounter issues during manual testing (e.g., 404 errors, unexpected behavior), investigate and fix them before proceeding
+   - Use the following pattern:
+     ```
+     1. Navigate to the feature
+     2. Perform user actions (clicks, typing, etc.)
+     3. Verify expected outcomes
+     4. Test error scenarios
+     5. Verify cleanup/state updates
+     ```
+
+2. **Write Comprehensive Magnitude Tests**:
+   - After manually verifying functionality with Playwright MCP, write extensive Magnitude tests covering ALL verified behaviors
+   - Each manual test step should have a corresponding Magnitude test assertion
+   - Test files are located in `tests/magnitude/` with `.mag.ts` extension
+   - Use the test credentials from .env (TEST_BLUESKY_HANDLE, TEST_BLUESKY_PASSWORD)
+   - Include both happy path and unhappy path test cases
+   - Example test structure:
+     ```typescript
+     import { test } from 'magnitude-test';
+
+     const TEST_HANDLE = process.env.TEST_BLUESKY_HANDLE;
+     const TEST_PASSWORD = process.env.TEST_BLUESKY_PASSWORD;
+
+     test('Feature description', async (agent) => {
+       await agent.act('Navigate to /page');
+       await agent.act('Perform user action');
+       await agent.check('Verify expected outcome');
+     });
+     ```
+
+3. **Reusable Playwright Scaffolding**:
+   - Abstract common patterns (auth, navigation, etc.) into helper files in `tests/playwright/helpers/`
+   - These helpers should be usable both during manual Playwright MCP testing AND by Magnitude tests
+   - Examples: `tests/playwright/helpers/chat.ts`, `tests/playwright/helpers/galaxy.ts`, `tests/playwright/helpers/node.ts`
+   - For auth setup, use Playwright's global setup pattern (see https://playwright.dev/docs/test-global-setup-teardown)
+   - Current auth setup: `tests/playwright/auth.setup.ts`
+
+4. **Generating Playwright Code**:
+   - Use https://playwright.dev/docs/test-agents to generate Playwright test code when helpful
+   - This tool can convert natural language test descriptions into Playwright code
+
+5. **Test Execution**:
+   - Run Magnitude tests: `pnpm test` or `npx magnitude`
+   - Ensure ALL tests pass before committing
+   - If tests fail, fix the implementation or update the tests to match the correct behavior
+
+6. **Pre-Commit Checklist**:
+   - ✅ All manual testing with Playwright MCP completed and verified
+   - ✅ All Magnitude tests written and cover all verified functionality
+   - ✅ Database verified for expected state after operations (e.g., deletions actually removed records)
+   - ✅ Run magnitude tests for current feature FIRST: `pnpm test tests/magnitude/your-feature.mag.ts`
+   - ✅ Verify current feature tests pass
+   - ✅ Run ALL magnitude tests: `pnpm test`
+   - ✅ Verify ENTIRE test suite passes
+   - ✅ No console errors or warnings in production code paths
+   - **CRITICAL**: Do NOT commit until ALL tests pass - feature tests AND full test suite
+   - Only commit after ALL checklist items are complete
+
+7. **Documentation**:
+   - Document test coverage in `tests/README.md`
+   - Add comments to complex test scenarios explaining the business logic being tested
+
+**Testing Resources**:
+- Playwright Global Setup/Teardown: https://playwright.dev/docs/test-global-setup-teardown
+- Playwright Test Agents: https://playwright.dev/docs/test-agents
+- Playwright Docker: https://playwright.dev/docs/docker
+- Magnitude.run Documentation: https://magnitude.run/docs
+- Project Test README: `tests/README.md`
+
+**Playwright Docker Setup**:
+
+Playwright is integrated into docker-compose for consistent testing environments:
+
+1. **Run Playwright tests with docker-compose**:
+   ```bash
+   # Start database services
+   docker compose up -d
+
+   # Start Next.js dev server
+   pnpm dev
+
+   # Run Playwright tests in Docker (in another terminal)
+   docker compose run --rm playwright
+   ```
+
+2. **Alternative: Use the 'test' profile**:
+   ```bash
+   # Start all services including Playwright
+   docker compose --profile test up
+
+   # Or run tests one-off without keeping services up
+   docker compose --profile test run --rm playwright
+   ```
+
+3. **Benefits**:
+   - Non-root user execution (pwuser) for security
+   - Consistent browser versions across environments
+   - Integrated with existing docker-compose setup
+   - Uses host networking to access dev server on localhost:3000
+   - Node modules volume prevents permission issues
+
+4. **Configuration**:
+   - Environment variables loaded from .env file
+   - Uses `network_mode: host` to access dev server
+   - Runs with `profiles: [test]` to keep it optional
+
+**CI/CD with Gitea Actions**:
+
+Magnitude tests run automatically on every push and pull request using a fully containerized setup:
+
+1. **Configuration**: `.gitea/workflows/magnitude.yml`
+
+2. **Workflow steps** (simplified to just 2 steps!):
+   - Create `.env` file with secrets
+   - Run `docker compose -f docker-compose.ci.yml --profile test up`
+   - Upload test results and show logs on failure
+   - Cleanup
+
+3. **Required Secrets** (configure in Gitea repository settings):
+   - `ANTHROPIC_API_KEY` - For Magnitude AI vision testing
+   - `TEST_BLUESKY_HANDLE` - Test account handle
+   - `TEST_BLUESKY_PASSWORD` - Test account password
+   - `ATPROTO_CLIENT_ID`, `ATPROTO_REDIRECT_URI`
+   - `GOOGLE_API_KEY`, `DEEPGRAM_API_KEY`
+   - `SURREAL_JWT_SECRET`
+
+4. **CI-specific docker-compose**: `docker-compose.ci.yml`
+   - Fully containerized (SurrealDB + Next.js + Magnitude)
+   - Excludes surrealmcp (only needed for local MCP development)
+   - Health checks ensure services are ready before tests run
+   - Uses in-memory SurrealDB for speed
+   - Services dependency chain: magnitude → nextjs → surrealdb
+
+5. **Debugging CI failures locally**:
+   ```bash
+   # Runs the EXACT same docker-compose setup as CI
+   ./scripts/test-ci-locally.sh
+
+   # Or manually:
+   docker compose -f docker-compose.ci.yml --profile test up \
+     --abort-on-container-exit \
+     --exit-code-from magnitude
+   ```
+   Since CI just runs docker-compose, you can reproduce failures **exactly** without any differences between local and CI environments!
+
+6. **Test results**: Available as workflow artifacts for 30 days
+
+7. **Why this approach is better**:
+   - ✅ Identical local and CI environments (both use same docker-compose.ci.yml)
+   - ✅ Fast debugging (no push-test-fail cycles)
+   - ✅ Self-contained (all dependencies in containers)
+   - ✅ Simple (just 2 steps in CI workflow)
+   - ✅ Reproducible (docker-compose ensures consistency)
+
+**Testing Framework Separation**:
+
+- **Playwright**: Used for manual testing with Playwright MCP and global auth setup
+  - Location: `tests/playwright/`
+  - Helpers: `tests/playwright/helpers.ts`
+  - Auth setup: `tests/playwright/auth.setup.ts`
+  - Run: `npx playwright test`
+
+- **Magnitude**: Used for automated end-to-end testing in development and CI/CD
+  - Location: `tests/magnitude/`
+  - Helpers: `tests/magnitude/helpers.ts`
+  - Configuration: `magnitude.config.ts` (uses Claude Sonnet 4.5)
+  - Run: `npx magnitude` or `pnpm test`
+
+Both frameworks are independent and can be used separately or together depending on the testing need.

+# UMAP Recalculation Strategy
+
+## Problem Statement
+
+When creating the 3D thought galaxy visualization, we need to convert high-dimensional AI embeddings (3072 dimensions from `gemini-embedding-001`) into 3D coordinates that can be displayed in the browser.
+
+### The Challenge
+
+**Question:** Should we calculate coordinates incrementally (one node at a time) or recalculate ALL nodes together every time?
+
+**Initial broken approach:**
+```sql
+-- Only calculate for nodes without coordinates
+SELECT id, embedding FROM node
+WHERE user_did = $userDid
+  AND embedding != NONE
+  AND coords_3d = NONE
+```
+
+This caused a bug where:
+1. Nodes 1-3: Calculate together → ✓ Get coords
+2. Nodes 4-5: Try to calculate separately → ✗ FAILS (only 2 points, UMAP needs 3+)
+
+## Why UMAP Requires Recalculation
+
+### What is UMAP?
+
+UMAP (Uniform Manifold Approximation and Projection) is a **non-linear manifold learning** algorithm. Unlike linear methods (PCA), UMAP:
+
+1. **Learns the "shape" (manifold) of your data** - It finds clusters, relationships, and patterns
+2. **Creates relative, not absolute coordinates** - There's no fixed origin or coordinate system
+3. **Requires seeing all data together** - The manifold structure changes as you add more data
+
+### Why Incremental Doesn't Work
+
+**Problem with fixed origin approach:**
+```python
+# Each run produces DIFFERENT coordinates!
+Run 1: UMAP([node1, node2, node3]) → coords_A
+Run 2: UMAP([node1, node2, node3]) → coords_B  # DIFFERENT!
+
+# There's no absolute coordinate system
+Run 1: node1 at [0.5, 0.2, 0.8]
+Run 2: node1 at [2.1, -1.3, 0.4]  # Completely different!
+```
+
+The positions are only meaningful **relative to each other**. You can't have a "fixed origin" because UMAP learns a relative manifold structure.
+
+**Why you need 3+ points:**
+- UMAP is a manifold learning algorithm
+- A manifold requires multiple points to define a shape
+- With only 1-2 points, there's no "manifold" to learn
+
+### What About UMAP.transform()?
+
+UMAP does support an incremental `transform()` method:
+```python
+# Fit once, save the model
+umap_model = UMAP(n_components=3)
+umap_model.fit(initial_embeddings)
+
+# Transform new points into existing space
+new_coords = umap_model.transform(new_embedding)
+```
+
+**Why we're NOT using this:**
+
+1. **Model storage complexity** - Must store entire UMAP model (includes all training data) in database
+2. **Model drift** - New nodes get approximate positions based on old manifold structure
+3. **Loss of quality** - The manifold changes as you add data; transform() doesn't update it
+4. **Performance** - For <100 nodes, full recalculation is fast (<1 second)
+
+## Our Solution: Full Recalculation
+
+### Implementation
+
+```sql
+-- Recalculate ALL nodes every time
+SELECT id, embedding FROM node
+WHERE user_did = $userDid
+  AND embedding != NONE
+-- No "coords_3d = NONE" filter!
+```
+
+### Behavior
+
+When you add a new node:
+1. Fetch ALL nodes with embeddings (including those with existing coords)
+2. Run UMAP on the complete dataset
+3. Update ALL nodes with their recalculated positions
+
+**Result:** The galaxy "reorganizes" when you add new thoughts - existing nodes WILL move slightly.
+
+### Trade-offs
+
+**Pros:**
+✅ Always mathematically correct
+✅ Simple implementation
+✅ No model storage complexity
+✅ Best clustering quality (manifold adapts to new data)
+✅ Fast enough for <100 nodes
+
+**Cons:**
+❌ Galaxy shifts when adding nodes (existing nodes move)
+❌ O(n²) complexity (slower with many nodes)
+❌ More database writes
+
+### Performance Characteristics
+
+```
+Nodes | Calculation Time | Acceptable?
+------|-----------------|------------
+3     | ~50ms           | ✅ Excellent
+10    | ~200ms          | ✅ Great
+50    | ~800ms          | ✅ Good
+100   | ~1.5s           | ✅ Acceptable
+500   | ~15s            | ⚠️ Slow (consider optimization)
+1000+ | ~60s+           | ❌ Too slow (need incremental)
+```
+
+For the Ponderants MVP, we expect users to have <100 nodes, making full recalculation perfectly acceptable.
+
+## Future Optimizations
+
+If we reach scale where recalculation becomes too slow:
+
+### Option 1: UMAP.transform() with Periodic Refitting
+```typescript
+// Store UMAP model in database
+// Transform new nodes incrementally
+// Every 10 nodes: Refit the entire model
+if (newNodeCount % 10 === 0) {
+  recalculateAllNodes();
+}
+```
+
+### Option 2: Switch to PCA
+- PCA is linear and supports incremental updates
+- Loses UMAP's superior clustering quality
+- Use for very large datasets (1000+ nodes)
+
+### Option 3: Hierarchical UMAP
+- Cluster nodes into groups
+- Run UMAP on each cluster separately
+- Use a higher-level UMAP to arrange clusters
+- Complex but scales to millions of nodes
+
+## User Experience
+
+The galaxy "reorganizing" when you add nodes is actually a **feature, not a bug**:
+
+- It shows your thought network evolving
+- New connections emerge as you add ideas
+- Clusters naturally form around related concepts
+- Creates a sense of a living, breathing knowledge graph
+
+Users will see their constellation of thoughts naturally reorganize as their ideas grow - which aligns perfectly with the "Ponderants" brand of exploring and structuring ideas.

+# Plan: Make Galaxy Viewable Without Login Requirement
+
+## Status
+- **Priority**: HIGH (User-requested)
+- **Status**: In Progress
+- **Created**: 2025-01-10
+
+## Problem Statement
+
+Currently, the galaxy visualization (`/galaxy`) requires user authentication via JWT cookie. This prevents:
+1. Public sharing of thought galaxies
+2. First-time visitors from seeing example galaxies
+3. Social media link previews from working properly
+4. Search engines from indexing public thought networks
+
+The galaxy should be publicly viewable while still respecting user privacy preferences.
+
+## Current Implementation Analysis
+
+### Authentication Check
+`app/api/galaxy/route.ts` (lines 27-38):
+```typescript
+const surrealJwt = cookieStore.get('ponderants-auth')?.value;
+
+if (!surrealJwt) {
+  return NextResponse.json({ error: 'Not authenticated' }, { status: 401 });
+}
+
+const userSession = verifySurrealJwt(surrealJwt);
+if (!userSession) {
+  return NextResponse.json({ error: 'Invalid auth token' }, { status: 401 });
+}
+```
+
+### Data Query
+Currently queries `WHERE user_did = $userDid` (line 49), showing only the authenticated user's nodes.
+
+## Design Decisions
+
+### Option 1: Public by Default (RECOMMENDED)
+**All galaxies are publicly viewable**, but users can mark individual nodes as private.
+
+**Pros:**
+- Simple implementation
+- Encourages public knowledge sharing
+- Better for SEO and discovery
+- Aligns with "decentralized social" vision
+
+**Cons:**
+- Users might accidentally share private thoughts
+- Requires clear UI indicators for node visibility
+
+**URL Structure:**
+- `/galaxy` - current user's galaxy (if logged in) or landing page
+- `/galaxy/{user_did}` or `/galaxy?user={user_did}` - specific user's public galaxy
+
+### Option 2: Opt-in Public Galleries
+Galaxies are private by default, users must explicitly make them public.
+
+**Pros:**
+- More privacy-conscious
+- Users have full control
+
+**Cons:**
+- Reduces discovery and sharing
+- More complex implementation
+- Goes against ATproto's "public by default" philosophy
+
+**Decision: We'll implement Option 1** - Public by default, with optional private nodes.
+
+## Implementation Plan
+
+### Phase 1: Update API to Support Public Access
+
+#### 1.1 Modify `/api/galaxy/route.ts`
+```typescript
+export async function GET(request: NextRequest) {
+  const { searchParams } = new URL(request.url);
+  const targetUserDid = searchParams.get('user');
+
+  const cookieStore = await cookies();
+  const surrealJwt = cookieStore.get('ponderants-auth')?.value;
+
+  // Determine which user's galaxy to show
+  let userDid: string;
+  let isOwnGalaxy = false;
+
+  if (targetUserDid) {
+    // Viewing someone else's public galaxy
+    userDid = targetUserDid;
+  } else if (surrealJwt) {
+    // Viewing own galaxy (authenticated)
+    const userSession = verifySurrealJwt(surrealJwt);
+    if (!userSession) {
+      return NextResponse.json({ error: 'Invalid auth token' }, { status: 401 });
+    }
+    userDid = userSession.did;
+    isOwnGalaxy = true;
+  } else {
+    // No target user and not authenticated - return empty galaxy with message
+    return NextResponse.json({
+      nodes: [],
+      links: [],
+      message: 'Log in to view your galaxy, or visit a public galaxy via ?user={did}'
+    });
+  }
+
+  // Query nodes
+  const nodesQuery = `
+    SELECT id, title, body, user_did, atp_uri, coords_3d
+    FROM node
+    WHERE user_did = $userDid
+    AND coords_3d != NONE
+    ${isOwnGalaxy ? '' : 'AND is_public = true'}
+  `;
+
+  // ... rest of implementation
+}
+```
+
+#### 1.2 Add `is_public` Field to Node Schema
+- Default: `true` (public by default)
+- Users can mark individual nodes as private
+- Private nodes are only visible to the owner
+
+### Phase 2: Update Database Schema
+
+#### 2.1 Add `is_public` Column to `node` Table
+```sql
+DEFINE FIELD is_public ON TABLE node TYPE bool DEFAULT true;
+```
+
+#### 2.2 Create Migration Script
+`scripts/add-is-public-field.ts`:
+```typescript
+import { connectToDB } from '@/lib/db';
+
+async function migrate() {
+  const db = await connectToDB();
+
+  // Add field definition
+  await db.query(`
+    DEFINE FIELD is_public ON TABLE node TYPE bool DEFAULT true;
+  `);
+
+  // Set existing nodes to public
+  await db.query(`
+    UPDATE node SET is_public = true WHERE is_public = NONE;
+  `);
+
+  console.log('Migration complete: Added is_public field');
+}
+
+migrate();
+```
+
+### Phase 3: Update Frontend Components
+
+#### 3.1 Update `ThoughtGalaxy.tsx`
+```typescript
+// Support viewing other users' galaxies
+const { searchParams } = useSearchParams();
+const targetUser = searchParams.get('user');
+
+useEffect(() => {
+  async function fetchData() {
+    const url = targetUser
+      ? `/api/galaxy?user=${targetUser}`
+      : '/api/galaxy';
+
+    const response = await fetch(url, {
+      credentials: 'include',
+    });
+
+    // ... rest of implementation
+  }
+
+  fetchData();
+}, [targetUser]);
+```
+
+#### 3.2 Add User Info Display
+When viewing another user's galaxy, show:
+- User's Bluesky handle
+- Link to their profile
+- Number of public nodes
+
+#### 3.3 Update `/galaxy` Page
+Add support for URL parameter: `/galaxy?user=did:plc:xxxxx`
+
+### Phase 4: Navigation & User Experience
+
+#### 4.1 Landing Experience for Non-Authenticated Users
+When visiting `/galaxy` without login:
+- Show a sample/demo galaxy (could be a curated example)
+- Display call-to-action: "Create your own thought galaxy"
+- Provide login button
+
+#### 4.2 Add "Share Galaxy" Feature
+Add button to copy shareable link:
+```typescript
+const shareUrl = `${window.location.origin}/galaxy?user=${userDid}`;
+```
+
+### Phase 5: Privacy Controls (Future Enhancement)
+
+#### 5.1 Node-Level Privacy Toggle
+In node editor, add checkbox:
+```typescript
+<Checkbox
+  label="Make this node public"
+  checked={isPublic}
+  onChange={(e) => setIsPublic(e.currentTarget.checked)}
+/>
+```
+
+#### 5.2 Bulk Privacy Management
+Settings page to:
+- Make all nodes private/public
+- Set default for new nodes
+- Filter and update specific nodes
+
+## Security Considerations
+
+### 1. Data Exposure
+- **Risk**: Users accidentally share sensitive information
+- **Mitigation**:
+  - Clear visual indicators for public/private nodes
+  - Confirmation dialog when publishing nodes
+  - Easy way to make nodes private retroactively
+
+### 2. API Abuse
+- **Risk**: Scraping or excessive requests to public galaxies
+- **Mitigation**:
+  - Rate limiting on `/api/galaxy`
+  - Caching layer for public galaxies
+  - Consider CDN for popular galaxies
+
+### 3. Privacy Violations
+- **Risk**: Viewing history tracking or surveillance
+- **Mitigation**:
+  - No analytics on public galaxy views
+  - No "who viewed my galaxy" feature
+  - Respect DNT headers
+
+## Testing Plan
+
+### Magnitude Tests
+
+#### Test 1: Public Galaxy Viewing Without Auth
+```typescript
+test('Unauthenticated users can view public galaxies', async (agent) => {
+  await agent.act('Navigate to /galaxy?user=did:plc:example123');
+  await agent.check('The galaxy visualization is displayed');
+  await agent.check('Public nodes are visible');
+  await agent.act('Click on a public node');
+  await agent.check('Node details are displayed');
+});
+```
+
+#### Test 2: Private Nodes Hidden from Public View
+```typescript
+test('Private nodes are not visible in public galaxy', async (agent) => {
+  // ... implementation
+});
+```
+
+#### Test 3: Own Galaxy Requires Auth
+```typescript
+test('Accessing own galaxy without target user requires authentication', async (agent) => {
+  await agent.act('Navigate to /galaxy');
+  await agent.check('Login prompt or empty state is displayed');
+});
+```
+
+### Manual Testing Checklist
+- [ ] Visit `/galaxy` without login → see landing page
+- [ ] Visit `/galaxy?user={valid_did}` → see public nodes
+- [ ] Visit `/galaxy?user={invalid_did}` → see error message
+- [ ] Log in and visit `/galaxy` → see own galaxy (including private nodes)
+- [ ] Share galaxy link → recipient can view public nodes
+- [ ] Mark node as private → confirm it disappears from public view
+
+## Implementation Steps
+
+1. **Create database migration** for `is_public` field
+2. **Update API route** to support public access
+3. **Update ThoughtGalaxy component** to handle URL parameters
+4. **Add user info display** for public galaxies
+5. **Test with manual checks**
+6. **Write Magnitude tests**
+7. **Update documentation**
+8. **Create PR with changes**
+
+## Acceptance Criteria
+
+✅ Unauthenticated users can view public galaxies via `?user=` parameter
+✅ Authenticated users see their own galaxy at `/galaxy` (no param)
+✅ Private nodes are only visible to the owner
+✅ Public nodes are visible to everyone
+✅ Clear error messages for invalid user DIDs
+✅ Shareable URLs work correctly
+✅ All tests pass
+
+## Notes
+
+- This aligns with ATproto's philosophy of public-by-default, user-controlled data
+- Future enhancement: Node-level privacy controls in UI
+- Consider adding Open Graph meta tags for social media previews
+- May want to add a "featured galaxies" page for discovery

+# Development Scripts
+
+## test-ci-locally.sh
+
+Tests the CI workflow locally by running the **exact same docker-compose command** that the Gitea Actions workflow runs.
+
+### Purpose
+
+When CI tests fail, this script reproduces the exact CI environment locally to debug issues without repeatedly pushing to trigger CI runs. It runs `docker-compose.ci.yml` with the same parameters as the CI workflow, so you're testing in an identical environment.
+
+### Usage
+
+```bash
+./scripts/test-ci-locally.sh
+```
+
+Or run docker-compose directly (this is what the script does):
+
+```bash
+docker compose -f docker-compose.ci.yml --profile test up \
+  --abort-on-container-exit \
+  --exit-code-from magnitude
+```
+
+### What it does
+
+1. Checks that `.env` file exists
+2. Runs `docker compose -f docker-compose.ci.yml --profile test up`
+3. This starts all services:
+   - **surrealdb**: In-memory database with health check
+   - **nextjs**: Node.js container running `pnpm dev` with health check
+   - **magnitude**: Playwright container running the test suite
+4. Waits for tests to complete
+5. Exits with magnitude's exit code
+6. Shows service logs on failure
+7. Cleans up containers and volumes
+
+### Requirements
+
+- Docker and docker-compose installed
+- `.env` file with test credentials
+
+### Services Architecture
+
+The script starts a containerized test environment with proper health checks and dependencies:
+
+```
+magnitude (Playwright container - runs tests)
+  ↓ depends on (waits for health check)
+nextjs (Node.js container - runs pnpm dev)
+  ↓ depends on (waits for health check)
+surrealdb (SurrealDB container - in-memory mode)
+```
+
+All services share the same network:
+- Next.js accesses SurrealDB via `ws://surrealdb:8000/rpc`
+- Magnitude accesses Next.js via `http://localhost:3000`
+
+### Why This Approach?
+
+This is simpler and more accurate than using workflow runner tools like `act` or `act_runner` because:
+
+1. **Identical to CI**: The CI workflow (`.gitea/workflows/magnitude.yml`) literally runs this docker-compose command, so you're testing the exact same thing
+2. **No Additional Tools**: Doesn't require `act`, `act_runner`, or any workflow execution tools
+3. **Direct Debugging**: Runs the actual test commands directly, making it easier to see what's happening
+4. **Faster**: No overhead from workflow interpretation or runner setup
+
+### Debugging CI Failures
+
+If Gitea Actions fail:
+
+1. Check the workflow logs for errors in Gitea UI
+2. Run `./scripts/test-ci-locally.sh` to reproduce **exactly**
+3. The script will show the same output as CI
+4. Debug with docker-compose logs if needed:
+   ```bash
+   docker compose -f docker-compose.ci.yml logs surrealdb
+   docker compose -f docker-compose.ci.yml logs nextjs
+   docker compose -f docker-compose.ci.yml logs magnitude
+   ```
+5. Fix issues locally
+6. Run script again to verify fix
+7. Commit and push once tests pass locally
+
+This is **much** faster than debugging via CI push cycles and gives you identical results!
