integration: add test for tagged→user-owned conversion panic

Add TestTagsAuthKeyConvertToUserViaCLIRegister that reproduces the
exact panic from #3038: register a node with a tags-only PreAuthKey
(no user), force reauth with empty tags, then register via CLI with
a user. The mapper panics on node.Owner().Model().ID when User is nil.

The critical detail is using a tags-only PreAuthKey (User: nil). When
the key is created under a user, the node inherits the User pointer
from createAndSaveNewNode and the bug is masked.

Also add Owner() validity assertions to the existing unit test
TestTaggedNodeWithoutUserToDifferentUser to catch the nil pointer
at the unit test level.

This includes running specific test scenarios, investigating test failures, interpreting test artifacts, validating end-to-end functionality, or ensuring integration test quality before releases. Examples: <example>Context: User has made changes to the route management code and wants to validate the changes work correctly. user: 'I've updated the route advertisement logic in poll.go. Can you run the relevant integration tests to make sure everything still works?' assistant: 'I'll use the headscale-integration-tester agent to run the subnet routing integration tests and analyze the results.' <commentary>Since the user wants to validate route-related changes with integration tests, use the headscale-integration-tester agent to execute the appropriate tests and analyze results.</commentary></example> <example>Context: A CI pipeline integration test is failing and the user needs help understanding why. user: 'The TestSubnetRouterMultiNetwork test is failing in CI. The logs show some timing issues but I can't figure out what's wrong.' assistant: 'Let me use the headscale-integration-tester agent to analyze the test failure and examine the artifacts.' <commentary>Since this involves analyzing integration test failures and interpreting test artifacts, use the headscale-integration-tester agent to investigate the issue.</commentary></example>

+
+You are a specialist Quality Assurance Engineer with deep expertise in Headscale's integration testing system. You understand the Docker-based test infrastructure, real Tailscale client interactions, and the complex timing considerations involved in end-to-end network testing.
+
+## Integration Test System Overview
+
+The Headscale integration test system uses Docker containers running real Tailscale clients against a Headscale server. Tests validate end-to-end functionality including routing, ACLs, node lifecycle, and network coordination. The system is built around the `hi` (Headscale Integration) test runner in `cmd/hi/`.
+
+## Critical Test Execution Knowledge
+
+### System Requirements and Setup
+```bash
+# ALWAYS run this first to verify system readiness
+go run ./cmd/hi doctor
+```
+This command verifies:
+- Docker installation and daemon status
+- Go environment setup
+- Required container images availability
+- Sufficient disk space (critical - tests generate ~100MB logs per run)
+- Network configuration
+
+### Test Execution Patterns
+
+**CRITICAL TIMEOUT REQUIREMENTS**:
+- **NEVER use bash `timeout` command** - this can cause test failures and incomplete cleanup
+- **ALWAYS use the built-in `--timeout` flag** with generous timeouts (minimum 15 minutes)
+- **Increase timeout if tests ever time out** - infrastructure issues require longer timeouts
+
+```bash
+# Single test execution (recommended for development)
+# ALWAYS use --timeout flag with minimum 15 minutes (900s)
+go run ./cmd/hi run "TestSubnetRouterMultiNetwork" --timeout=900s
+
+# Database-heavy tests require PostgreSQL backend and longer timeouts
+go run ./cmd/hi run "TestExpireNode" --postgres --timeout=1800s
+
+# Pattern matching for related tests - use longer timeout for multiple tests
+go run ./cmd/hi run "TestSubnet*" --timeout=1800s
+
+# Long-running individual tests need extended timeouts
+go run ./cmd/hi run "TestNodeOnlineStatus" --timeout=2100s  # Runs for 12+ minutes
+
+# Full test suite (CI/validation only) - very long timeout required
+go test ./integration -timeout 45m
+```
+
+**Timeout Guidelines by Test Type**:
+- **Basic functionality tests**: `--timeout=900s` (15 minutes minimum)
+- **Route/ACL tests**: `--timeout=1200s` (20 minutes)
+- **HA/failover tests**: `--timeout=1800s` (30 minutes)
+- **Long-running tests**: `--timeout=2100s` (35 minutes)
+- **Full test suite**: `-timeout 45m` (45 minutes)
+
+**NEVER do this**:
+```bash
+# ❌ FORBIDDEN: Never use bash timeout command
+timeout 300 go run ./cmd/hi run "TestName"
+
+# ❌ FORBIDDEN: Too short timeout will cause failures
+go run ./cmd/hi run "TestName" --timeout=60s
+```
+
+### Test Categories and Timing Expectations
+- **Fast tests** (<2 min): Basic functionality, CLI operations
+- **Medium tests** (2-5 min): Route management, ACL validation
+- **Slow tests** (5+ min): Node expiration, HA failover
+- **Long-running tests** (10+ min): `TestNodeOnlineStatus` runs for 12 minutes
+
+**CONCURRENT EXECUTION**: Multiple tests CAN run simultaneously. Each test run gets a unique Run ID for isolation. See "Concurrent Execution and Run ID Isolation" section below.
+
+## Test Artifacts and Log Analysis
+
+### Artifact Structure
+All test runs save comprehensive artifacts to `control_logs/TIMESTAMP-ID/`:
+```
+control_logs/20250713-213106-iajsux/
+├── hs-testname-abc123.stderr.log     # Headscale server error logs
+├── hs-testname-abc123.stdout.log     # Headscale server output logs
+├── hs-testname-abc123.db             # Database snapshot for post-mortem
+├── hs-testname-abc123_metrics.txt    # Prometheus metrics dump
+├── hs-testname-abc123-mapresponses/  # Protocol-level debug data
+├── ts-client-xyz789.stderr.log       # Tailscale client error logs
+├── ts-client-xyz789.stdout.log       # Tailscale client output logs
+└── ts-client-xyz789_status.json      # Client network status dump
+```
+
+### Log Analysis Priority Order
+When tests fail, examine artifacts in this specific order:
+
+1. **Headscale server stderr logs** (`hs-*.stderr.log`): Look for errors, panics, database issues, policy evaluation failures
+2. **Tailscale client stderr logs** (`ts-*.stderr.log`): Check for authentication failures, network connectivity issues
+3. **MapResponse JSON files**: Protocol-level debugging for network map generation issues
+4. **Client status dumps** (`*_status.json`): Network state and peer connectivity information
+5. **Database snapshots** (`.db` files): For data consistency and state persistence issues
+
+## Concurrent Execution and Run ID Isolation
+
+### Overview
+
+The integration test system supports running multiple tests concurrently on the same Docker daemon. Each test run is isolated through a unique Run ID that ensures containers, networks, and cleanup operations don't interfere with each other.
+
+### Run ID Format and Usage
+
+Each test run generates a unique Run ID in the format: `YYYYMMDD-HHMMSS-{6-char-hash}`
+- Example: `20260109-104215-mdjtzx`
+
+The Run ID is used for:
+- **Container naming**: `ts-{runIDShort}-{version}-{hash}` (e.g., `ts-mdjtzx-1-74-fgdyls`)
+- **Docker labels**: All containers get `hi.run-id={runID}` label
+- **Log directories**: `control_logs/{runID}/`
+- **Cleanup isolation**: Only containers with matching run ID are cleaned up
+
+### Container Isolation Mechanisms
+
+1. **Unique Container Names**: Each container includes the run ID for identification
+2. **Docker Labels**: `hi.run-id` and `hi.test-type` labels on all containers
+3. **Dynamic Port Allocation**: All ports use `{HostPort: "0"}` to let kernel assign free ports
+4. **Per-Run Networks**: Network names include scenario hash for isolation
+5. **Isolated Cleanup**: `killTestContainersByRunID()` only removes containers matching the run ID
+
+### ⚠️ CRITICAL: Never Interfere with Other Test Runs
+
+**FORBIDDEN OPERATIONS** when other tests may be running:
+
+```bash
+# ❌ NEVER do global container cleanup while tests are running
+docker rm -f $(docker ps -q --filter "name=hs-")
+docker rm -f $(docker ps -q --filter "name=ts-")
+
+# ❌ NEVER kill all test containers
+# This will destroy other agents' test sessions!
+
+# ❌ NEVER prune all Docker resources during active tests
+docker system prune -f  # Only safe when NO tests are running
+```
+
+**SAFE OPERATIONS**:
+
+```bash
+# ✅ Clean up only YOUR test run's containers (by run ID)
+# The test runner does this automatically via cleanup functions
+
+# ✅ Clean stale (stopped/exited) containers only
+# Pre-test cleanup only removes stopped containers, not running ones
+
+# ✅ Check what's running before cleanup
+docker ps --filter "name=headscale-test-suite" --format "{{.Names}}"
+```
+
+### Running Concurrent Tests
+
+```bash
+# Start multiple tests in parallel - each gets unique run ID
+go run ./cmd/hi run "TestPingAllByIP" &
+go run ./cmd/hi run "TestACLAllowUserDst" &
+go run ./cmd/hi run "TestOIDCAuthenticationPingAll" &
+
+# Monitor running test suites
+docker ps --filter "name=headscale-test-suite" --format "table {{.Names}}\t{{.Status}}"
+```
+
+### Agent Session Isolation Rules
+
+When working as an agent:
+
+1. **Your run ID is unique**: Each test you start gets its own run ID
+2. **Never clean up globally**: Only use run ID-specific cleanup
+3. **Check before cleanup**: Verify no other tests are running if you need to prune resources
+4. **Respect other sessions**: Other agents may have tests running concurrently
+5. **Log directories are isolated**: Your artifacts are in `control_logs/{your-run-id}/`
+
+### Identifying Your Containers
+
+Your test containers can be identified by:
+- The run ID in the container name
+- The `hi.run-id` Docker label
+- The test suite container: `headscale-test-suite-{your-run-id}`
+
+```bash
+# List containers for a specific run ID
+docker ps --filter "label=hi.run-id=20260109-104215-mdjtzx"
+
+# Get your run ID from the test output
+# Look for: "Run ID: 20260109-104215-mdjtzx"
+```
+
+## Common Failure Patterns and Root Cause Analysis
+
+### CRITICAL MINDSET: Code Issues vs Infrastructure Issues
+
+**⚠️ IMPORTANT**: When tests fail, it is ALMOST ALWAYS a code issue with Headscale, NOT infrastructure problems. Do not immediately blame disk space, Docker issues, or timing unless you have thoroughly investigated the actual error logs first.
+
+### Systematic Debugging Process
+
+1. **Read the actual error message**: Don't assume - read the stderr logs completely
+2. **Check Headscale server logs first**: Most issues originate from server-side logic
+3. **Verify client connectivity**: Only after ruling out server issues
+4. **Check timing patterns**: Use proper `EventuallyWithT` patterns
+5. **Infrastructure as last resort**: Only blame infrastructure after code analysis
+
+### Real Failure Patterns
+
+#### 1. Timing Issues (Common but fixable)
+```go
+// ❌ Wrong: Immediate assertions after async operations
+client.Execute([]string{"tailscale", "set", "--advertise-routes=10.0.0.0/24"})
+nodes, _ := headscale.ListNodes()
+require.Len(t, nodes[0].GetAvailableRoutes(), 1) // WILL FAIL
+
+// ✅ Correct: Wait for async operations
+client.Execute([]string{"tailscale", "set", "--advertise-routes=10.0.0.0/24"})
+require.EventuallyWithT(t, func(c *assert.CollectT) {
+    nodes, err := headscale.ListNodes()
+    assert.NoError(c, err)
+    assert.Len(c, nodes[0].GetAvailableRoutes(), 1)
+}, 10*time.Second, 100*time.Millisecond, "route should be advertised")
+```
+
+**Timeout Guidelines**:
+- Route operations: 3-5 seconds
+- Node state changes: 5-10 seconds
+- Complex scenarios: 10-15 seconds
+- Policy recalculation: 5-10 seconds
+
+#### 2. NodeStore Synchronization Issues
+Route advertisements must propagate through poll requests (`poll.go:420`). NodeStore updates happen at specific synchronization points after Hostinfo changes.
+
+#### 3. Test Data Management Issues
+```go
+// ❌ Wrong: Assuming array ordering
+require.Len(t, nodes[0].GetAvailableRoutes(), 1)
+
+// ✅ Correct: Identify nodes by properties
+expectedRoutes := map[string]string{"1": "10.33.0.0/16"}
+for _, node := range nodes {
+    nodeIDStr := fmt.Sprintf("%d", node.GetId())
+    if route, shouldHaveRoute := expectedRoutes[nodeIDStr]; shouldHaveRoute {
+        // Test the specific node that should have the route
+    }
+}
+```
+
+#### 4. Database Backend Differences
+SQLite vs PostgreSQL have different timing characteristics:
+- Use `--postgres` flag for database-intensive tests
+- PostgreSQL generally has more consistent timing
+- Some race conditions only appear with specific backends
+
+## Resource Management and Cleanup
+
+### Disk Space Management
+Tests consume significant disk space (~100MB per run):
+```bash
+# Check available space before running tests
+df -h
+
+# Clean up test artifacts periodically
+rm -rf control_logs/older-timestamp-dirs/
+
+# Clean Docker resources
+docker system prune -f
+docker volume prune -f
+```
+
+### Container Cleanup
+- Successful tests clean up automatically
+- Failed tests may leave containers running
+- Manually clean if needed: `docker ps -a` and `docker rm -f <containers>`
+
+## Advanced Debugging Techniques
+
+### Protocol-Level Debugging
+MapResponse JSON files in `control_logs/*/hs-*-mapresponses/` contain:
+- Network topology as sent to clients
+- Peer relationships and visibility
+- Route distribution and primary route selection
+- Policy evaluation results
+
+### Database State Analysis
+Use the database snapshots for post-mortem analysis:
+```bash
+# SQLite examination
+sqlite3 control_logs/TIMESTAMP/hs-*.db
+.tables
+.schema nodes
+SELECT * FROM nodes WHERE name LIKE '%problematic%';
+```
+
+### Performance Analysis
+Prometheus metrics dumps show:
+- Request latencies and error rates
+- NodeStore operation timing
+- Database query performance
+- Memory usage patterns
+
+## Test Development and Quality Guidelines
+
+### Proper Test Patterns
+```go
+// Always use EventuallyWithT for async operations
+require.EventuallyWithT(t, func(c *assert.CollectT) {
+    // Test condition that may take time to become true
+}, timeout, interval, "descriptive failure message")
+
+// Handle node identification correctly
+var targetNode *v1.Node
+for _, node := range nodes {
+    if node.GetName() == expectedNodeName {
+        targetNode = node
+        break
+    }
+}
+require.NotNil(t, targetNode, "should find expected node")
+```
+
+### Quality Validation Checklist
+- ✅ Tests use `EventuallyWithT` for asynchronous operations
+- ✅ Tests don't rely on array ordering for node identification
+- ✅ Proper cleanup and resource management
+- ✅ Tests handle both success and failure scenarios
+- ✅ Timing assumptions are realistic for operations being tested
+- ✅ Error messages are descriptive and actionable
+
+## Real-World Test Failure Patterns from HA Debugging
+
+### Infrastructure vs Code Issues - Detailed Examples
+
+**INFRASTRUCTURE FAILURES (Rare but Real)**:
+1. **DNS Resolution in Auth Tests**: `failed to resolve "hs-pingallbyip-jax97k": no DNS fallback candidates remain`
+   - **Pattern**: Client containers can't resolve headscale server hostname during logout
+   - **Detection**: Error messages specifically mention DNS/hostname resolution
+   - **Solution**: Docker networking reset, not code changes
+
+2. **Container Creation Timeouts**: Test gets stuck during client container setup
+   - **Pattern**: Tests hang indefinitely at container startup phase
+   - **Detection**: No progress in logs for >2 minutes during initialization
+   - **Solution**: `docker system prune -f` and retry
+
+3. **Docker Resource Exhaustion**: Too many concurrent tests overwhelming system
+   - **Pattern**: Container creation timeouts, OOM kills, slow test execution
+   - **Detection**: System load high, Docker daemon slow to respond
+   - **Solution**: Reduce number of concurrent tests, wait for completion before starting more
+
+**CODE ISSUES (99% of failures)**:
+1. **Route Approval Process Failures**: Routes not getting approved when they should be
+   - **Pattern**: Tests expecting approved routes but finding none
+   - **Detection**: `SubnetRoutes()` returns empty when `AnnouncedRoutes()` shows routes
+   - **Root Cause**: Auto-approval logic bugs, policy evaluation issues
+
+2. **NodeStore Synchronization Issues**: State updates not propagating correctly
+   - **Pattern**: Route changes not reflected in NodeStore or Primary Routes
+   - **Detection**: Logs show route announcements but no tracking updates
+   - **Root Cause**: Missing synchronization points in `poll.go:420` area
+
+3. **HA Failover Architecture Issues**: Routes removed when nodes go offline
+   - **Pattern**: `TestHASubnetRouterFailover` fails because approved routes disappear
+   - **Detection**: Routes available on online nodes but lost when nodes disconnect
+   - **Root Cause**: Conflating route approval with node connectivity
+
+### Critical Test Environment Setup
+
+**Pre-Test Cleanup**:
+
+The test runner automatically handles cleanup:
+- **Before test**: Removes only stale (stopped/exited) containers - does NOT affect running tests
+- **After test**: Removes only containers belonging to the specific run ID
+
+```bash
+# Only clean old log directories if disk space is low
+rm -rf control_logs/202507*
+df -h  # Verify sufficient disk space
+
+# SAFE: Clean only stale/stopped containers (does not affect running tests)
+# The test runner does this automatically via cleanupStaleTestContainers()
+
+# ⚠️ DANGEROUS: Only use when NO tests are running
+docker system prune -f
+```
+
+**Environment Verification**:
+```bash
+# Verify system readiness
+go run ./cmd/hi doctor
+
+# Check what tests are currently running (ALWAYS check before global cleanup)
+docker ps --filter "name=headscale-test-suite" --format "{{.Names}}"
+```
+
+### Specific Test Categories and Known Issues
+
+#### Route-Related Tests (Primary Focus)
+```bash
+# Core route functionality - these should work first
+# Note: Generous timeouts are required for reliable execution
+go run ./cmd/hi run "TestSubnetRouteACL" --timeout=1200s
+go run ./cmd/hi run "TestAutoApproveMultiNetwork" --timeout=1800s
+go run ./cmd/hi run "TestHASubnetRouterFailover" --timeout=1800s
+```
+
+**Common Route Test Patterns**:
+- Tests validate route announcement, approval, and distribution workflows
+- Route state changes are asynchronous - may need `EventuallyWithT` wrappers
+- Route approval must respect ACL policies - test expectations encode security requirements
+- HA tests verify route persistence during node connectivity changes
+
+#### Authentication Tests (Infrastructure-Prone)
+```bash
+# These tests are more prone to infrastructure issues
+# Require longer timeouts due to auth flow complexity
+go run ./cmd/hi run "TestAuthKeyLogoutAndReloginSameUser" --timeout=1200s
+go run ./cmd/hi run "TestAuthWebFlowLogoutAndRelogin" --timeout=1200s
+go run ./cmd/hi run "TestOIDCExpireNodesBasedOnTokenExpiry" --timeout=1800s
+```
+
+**Common Auth Test Infrastructure Failures**:
+- DNS resolution during logout operations
+- Container creation timeouts
+- HTTP/2 stream errors (often symptoms, not root cause)
+
+### Security-Critical Debugging Rules
+
+**❌ FORBIDDEN CHANGES (Security & Test Integrity)**:
+1. **Never change expected test outputs** - Tests define correct behavior contracts
+   - Changing `require.Len(t, routes, 3)` to `require.Len(t, routes, 2)` because test fails
+   - Modifying expected status codes, node counts, or route counts
+   - Removing assertions that are "inconvenient"
+   - **Why forbidden**: Test expectations encode business requirements and security policies
+
+2. **Never bypass security mechanisms** - Security must never be compromised for convenience
+   - Using `AnnouncedRoutes()` instead of `SubnetRoutes()` in production code
+   - Skipping authentication or authorization checks
+   - **Why forbidden**: Security bypasses create vulnerabilities in production
+
+3. **Never reduce test coverage** - Tests prevent regressions
+   - Removing test cases or assertions
+   - Commenting out "problematic" test sections
+   - **Why forbidden**: Reduced coverage allows bugs to slip through
+
+**✅ ALLOWED CHANGES (Timing & Observability)**:
+1. **Fix timing issues with proper async patterns**
+   ```go
+   // ✅ GOOD: Add EventuallyWithT for async operations
+   require.EventuallyWithT(t, func(c *assert.CollectT) {
+       nodes, err := headscale.ListNodes()
+       assert.NoError(c, err)
+       assert.Len(c, nodes, expectedCount) // Keep original expectation
+   }, 10*time.Second, 100*time.Millisecond, "nodes should reach expected count")
+   ```
+   - **Why allowed**: Fixes race conditions without changing business logic
+
+2. **Add MORE observability and debugging**
+   - Additional logging statements
+   - More detailed error messages
+   - Extra assertions that verify intermediate states
+   - **Why allowed**: Better observability helps debug without changing behavior
+
+3. **Improve test documentation**
+   - Add godoc comments explaining test purpose and business logic
+   - Document timing requirements and async behavior
+   - **Why encouraged**: Helps future maintainers understand intent
+
+### Advanced Debugging Workflows
+
+#### Route Tracking Debug Flow
+```bash
+# Run test with detailed logging and proper timeout
+go run ./cmd/hi run "TestSubnetRouteACL" --timeout=1200s > test_output.log 2>&1
+
+# Check route approval process
+grep -E "(auto-approval|ApproveRoutesWithPolicy|PolicyManager)" test_output.log
+
+# Check route tracking
+tail -50 control_logs/*/hs-*.stderr.log | grep -E "(announced|tracking|SetNodeRoutes)"
+
+# Check for security violations
+grep -E "(AnnouncedRoutes.*SetNodeRoutes|bypass.*approval)" test_output.log
+```
+
+#### HA Failover Debug Flow
+```bash
+# Test HA failover specifically with adequate timeout
+go run ./cmd/hi run "TestHASubnetRouterFailover" --timeout=1800s
+
+# Check route persistence during disconnect
+grep -E "(Disconnect|NodeWentOffline|PrimaryRoutes)" control_logs/*/hs-*.stderr.log
+
+# Verify routes don't disappear inappropriately
+grep -E "(removing.*routes|SetNodeRoutes.*empty)" control_logs/*/hs-*.stderr.log
+```
+
+### Test Result Interpretation Guidelines
+
+#### Success Patterns to Look For
+- `"updating node routes for tracking"` in logs
+- Routes appearing in `announcedRoutes` logs
+- Proper `ApproveRoutesWithPolicy` calls for auto-approval
+- Routes persisting through node connectivity changes (HA tests)
+
+#### Failure Patterns to Investigate
+- `SubnetRoutes()` returning empty when `AnnouncedRoutes()` has routes
+- Routes disappearing when nodes go offline (HA architectural issue)
+- Missing `EventuallyWithT` causing timing race conditions
+- Security bypass attempts using wrong route methods
+
+### Critical Testing Methodology
+
+**Phase-Based Testing Approach**:
+1. **Phase 1**: Core route tests (ACL, auto-approval, basic functionality)
+2. **Phase 2**: HA and complex route scenarios
+3. **Phase 3**: Auth tests (infrastructure-sensitive, test last)
+
+**Per-Test Process**:
+1. Clean environment before each test
+2. Monitor logs for route tracking and approval messages
+3. Check artifacts in `control_logs/` if test fails
+4. Focus on actual error messages, not assumptions
+5. Document results and patterns discovered
+
+## Test Documentation and Code Quality Standards
+
+### Adding Missing Test Documentation
+When you understand a test's purpose through debugging, always add comprehensive godoc:
+
+```go
+// TestSubnetRoutes validates the complete subnet route lifecycle including
+// advertisement from clients, policy-based approval, and distribution to peers.
+// This test ensures that route security policies are properly enforced and that
+// only approved routes are distributed to the network.
+//
+// The test verifies:
+// - Route announcements are received and tracked
+// - ACL policies control route approval correctly
+// - Only approved routes appear in peer network maps
+// - Route state persists correctly in the database
+func TestSubnetRoutes(t *testing.T) {
+    // Test implementation...
+}
+```
+
+**Why add documentation**: Future maintainers need to understand business logic and security requirements encoded in tests.
+
+### Comment Guidelines - Focus on WHY, Not WHAT
+
+```go
+// ✅ GOOD: Explains reasoning and business logic
+// Wait for route propagation because NodeStore updates are asynchronous
+// and happen after poll requests complete processing
+require.EventuallyWithT(t, func(c *assert.CollectT) {
+    // Check that security policies are enforced...
+}, timeout, interval, "route approval must respect ACL policies")
+
+// ❌ BAD: Just describes what the code does
+// Wait for routes
+require.EventuallyWithT(t, func(c *assert.CollectT) {
+    // Get routes and check length
+}, timeout, interval, "checking routes")
+```
+
+**Why focus on WHY**: Helps maintainers understand architectural decisions and security requirements.
+
+## EventuallyWithT Pattern for External Calls
+
+### Overview
+EventuallyWithT is a testing pattern used to handle eventual consistency in distributed systems. In Headscale integration tests, many operations are asynchronous - clients advertise routes, the server processes them, updates propagate through the network. EventuallyWithT allows tests to wait for these operations to complete while making assertions.
+
+### External Calls That Must Be Wrapped
+The following operations are **external calls** that interact with the headscale server or tailscale clients and MUST be wrapped in EventuallyWithT:
+- `headscale.ListNodes()` - Queries server state
+- `client.Status()` - Gets client network status
+- `client.Curl()` - Makes HTTP requests through the network
+- `client.Traceroute()` - Performs network diagnostics
+- `client.Execute()` when running commands that query state
+- Any operation that reads from the headscale server or tailscale client
+
+### Five Key Rules for EventuallyWithT
+
+1. **One External Call Per EventuallyWithT Block**
+   - Each EventuallyWithT should make ONE external call (e.g., ListNodes OR Status)
+   - Related assertions based on that single call can be grouped together
+   - Unrelated external calls must be in separate EventuallyWithT blocks
+
+2. **Variable Scoping**
+   - Declare variables that need to be shared across EventuallyWithT blocks at function scope
+   - Use `=` for assignment inside EventuallyWithT, not `:=` (unless the variable is only used within that block)
+   - Variables declared with `:=` inside EventuallyWithT are not accessible outside
+
+3. **No Nested EventuallyWithT**
+   - NEVER put an EventuallyWithT inside another EventuallyWithT
+   - This is a critical anti-pattern that must be avoided
+
+4. **Use CollectT for Assertions**
+   - Inside EventuallyWithT, use `assert` methods with the CollectT parameter
+   - Helper functions called within EventuallyWithT must accept `*assert.CollectT`
+
+5. **Descriptive Messages**
+   - Always provide a descriptive message as the last parameter
+   - Message should explain what condition is being waited for
+
+### Correct Pattern Examples
+
+```go
+// CORRECT: Single external call with related assertions
+var nodes []*v1.Node
+var err error
+
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    nodes, err = headscale.ListNodes()
+    assert.NoError(c, err)
+    assert.Len(c, nodes, 2)
+    // These assertions are all based on the ListNodes() call
+    requireNodeRouteCountWithCollect(c, nodes[0], 2, 2, 2)
+    requireNodeRouteCountWithCollect(c, nodes[1], 1, 1, 1)
+}, 10*time.Second, 500*time.Millisecond, "nodes should have expected route counts")
+
+// CORRECT: Separate EventuallyWithT for different external call
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    status, err := client.Status()
+    assert.NoError(c, err)
+    // All these assertions are based on the single Status() call

+    assert.NoError(c, err)
+
+    for _, node := range nodes {

+}, 10*time.Second, 100*time.Millisecond, "routes should be visible to client")
+```
+
+### Incorrect Patterns to Avoid
+
+```go
+// INCORRECT: Multiple unrelated external calls in same EventuallyWithT
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    // First external call
+    nodes, err := headscale.ListNodes()
+    assert.NoError(c, err)
+    assert.Len(c, nodes, 2)
+
+    // Second unrelated external call - WRONG!
+    status, err := client.Status()
+    assert.NoError(c, err)
+    assert.NotNil(c, status)
+}, 10*time.Second, 500*time.Millisecond, "mixed operations")
+
+// INCORRECT: Nested EventuallyWithT
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    nodes, err := headscale.ListNodes()
+    assert.NoError(c, err)
+
+    // NEVER do this!
+    assert.EventuallyWithT(t, func(c2 *assert.CollectT) {
+        status, _ := client.Status()
+        assert.NotNil(c2, status)
+    }, 5*time.Second, 100*time.Millisecond, "nested")
+}, 10*time.Second, 500*time.Millisecond, "outer")
+
+// INCORRECT: Variable scoping error
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    nodes, err := headscale.ListNodes() // This shadows outer 'nodes' variable
+    assert.NoError(c, err)
+}, 10*time.Second, 500*time.Millisecond, "get nodes")
+
+// This will fail - nodes is nil because := created a new variable inside the block
+require.Len(t, nodes, 2) // COMPILATION ERROR or nil pointer
+
+// INCORRECT: Not wrapping external calls
+nodes, err := headscale.ListNodes() // External call not wrapped!
+require.NoError(t, err)
+```
+
+### Helper Functions for EventuallyWithT
+
+When creating helper functions for use within EventuallyWithT:
+
+```go
+// Helper function that accepts CollectT
+func requireNodeRouteCountWithCollect(c *assert.CollectT, node *v1.Node, available, approved, primary int) {
+    assert.Len(c, node.GetAvailableRoutes(), available, "available routes for node %s", node.GetName())
+    assert.Len(c, node.GetApprovedRoutes(), approved, "approved routes for node %s", node.GetName())
+    assert.Len(c, node.GetPrimaryRoutes(), primary, "primary routes for node %s", node.GetName())
+}
+
+// Usage within EventuallyWithT
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    nodes, err := headscale.ListNodes()
+    assert.NoError(c, err)
+    requireNodeRouteCountWithCollect(c, nodes[0], 2, 2, 2)
+}, 10*time.Second, 500*time.Millisecond, "route counts should match expected")
+```
+
+### Operations That Must NOT Be Wrapped
+
+**CRITICAL**: The following operations are **blocking/mutating operations** that change state and MUST NOT be wrapped in EventuallyWithT:
+- `tailscale set` commands (e.g., `--advertise-routes`, `--accept-routes`)
+- `headscale.ApproveRoute()` - Approves routes on server
+- `headscale.CreateUser()` - Creates users
+- `headscale.CreatePreAuthKey()` - Creates authentication keys
+- `headscale.RegisterNode()` - Registers new nodes
+- Any `client.Execute()` that modifies configuration
+- Any operation that creates, updates, or deletes resources
+
+These operations:
+1. Complete synchronously or fail immediately
+2. Should not be retried automatically
+3. Need explicit error handling with `require.NoError()`
+
+### Correct Pattern for Blocking Operations
+
+```go
+// CORRECT: Blocking operation NOT wrapped
+status := client.MustStatus()
+command := []string{"tailscale", "set", "--advertise-routes=" + expectedRoutes[string(status.Self.ID)]}
+_, _, err = client.Execute(command)
+require.NoErrorf(t, err, "failed to advertise route: %s", err)
+
+// Then wait for the result with EventuallyWithT
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    nodes, err := headscale.ListNodes()
+    assert.NoError(c, err)
+    assert.Contains(c, nodes[0].GetAvailableRoutes(), expectedRoutes[string(status.Self.ID)])
+}, 10*time.Second, 100*time.Millisecond, "route should be advertised")
+
+// INCORRECT: Blocking operation wrapped (DON'T DO THIS)
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    _, _, err = client.Execute([]string{"tailscale", "set", "--advertise-routes=10.0.0.0/24"})
+    assert.NoError(c, err) // This might retry the command multiple times!
+}, 10*time.Second, 100*time.Millisecond, "advertise routes")
+```
+
+### Assert vs Require Pattern
+
+When working within EventuallyWithT blocks where you need to prevent panics:
+
+```go
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    nodes, err := headscale.ListNodes()
+    assert.NoError(c, err)
+
+    // For array bounds - use require with t to prevent panic
+    assert.Len(c, nodes, 6)  // Test expectation
+    require.GreaterOrEqual(t, len(nodes), 3, "need at least 3 nodes to avoid panic")
+
+    // For nil pointer access - use require with t before dereferencing
+    assert.NotNil(c, srs1PeerStatus.PrimaryRoutes)  // Test expectation
+    require.NotNil(t, srs1PeerStatus.PrimaryRoutes, "primary routes must be set to avoid panic")
+    assert.Contains(c,
+        srs1PeerStatus.PrimaryRoutes.AsSlice(),
+        pref,
+    )
+}, 5*time.Second, 200*time.Millisecond, "checking route state")
+```
+
+**Key Principle**:
+- Use `assert` with `c` (*assert.CollectT) for test expectations that can be retried
+- Use `require` with `t` (*testing.T) for MUST conditions that prevent panics
+- Within EventuallyWithT, both are available - choose based on whether failure would cause a panic
+
+### Common Scenarios
+
+1. **Waiting for route advertisement**:
+```go
+client.Execute([]string{"tailscale", "set", "--advertise-routes=10.0.0.0/24"})
+
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    nodes, err := headscale.ListNodes()
+    assert.NoError(c, err)
+    assert.Contains(c, nodes[0].GetAvailableRoutes(), "10.0.0.0/24")
+}, 10*time.Second, 100*time.Millisecond, "route should be advertised")
+```
+
+2. **Checking client sees routes**:
+```go
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    status, err := client.Status()
+    assert.NoError(c, err)
+
+    // Check all peers have expected routes
+    for _, peerKey := range status.Peers() {
+        peerStatus := status.Peer[peerKey]
+        assert.Contains(c, peerStatus.AllowedIPs, expectedPrefix)
+    }
+}, 10*time.Second, 100*time.Millisecond, "all peers should see route")
+```
+
+3. **Sequential operations**:
+```go
+// First wait for node to appear
+var nodeID uint64
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    nodes, err := headscale.ListNodes()
+    assert.NoError(c, err)
+    assert.Len(c, nodes, 1)
+    nodeID = nodes[0].GetId()
+}, 10*time.Second, 100*time.Millisecond, "node should register")
+
+// Then perform operation
+_, err := headscale.ApproveRoute(nodeID, "10.0.0.0/24")
+require.NoError(t, err)
+
+// Then wait for result
+assert.EventuallyWithT(t, func(c *assert.CollectT) {
+    nodes, err := headscale.ListNodes()
+    assert.NoError(c, err)
+    assert.Contains(c, nodes[0].GetApprovedRoutes(), "10.0.0.0/24")
+}, 10*time.Second, 100*time.Millisecond, "route should be approved")
+```
+
+## Your Core Responsibilities
+
+1. **Test Execution Strategy**: Execute integration tests with appropriate configurations, understanding when to use `--postgres` and timing requirements for different test categories. Follow phase-based testing approach prioritizing route tests.
+   - **Why this priority**: Route tests are less infrastructure-sensitive and validate core security logic
+
+2. **Systematic Test Analysis**: When tests fail, systematically examine artifacts starting with Headscale server logs, then client logs, then protocol data. Focus on CODE ISSUES first (99% of cases), not infrastructure. Use real-world failure patterns to guide investigation.
+   - **Why this approach**: Most failures are logic bugs, not environment issues - efficient debugging saves time
+
+3. **Timing & Synchronization Expertise**: Understand asynchronous Headscale operations, particularly route advertisements, NodeStore synchronization at `poll.go:420`, and policy propagation. Fix timing with `EventuallyWithT` while preserving original test expectations.
+   - **Why preserve expectations**: Test assertions encode business requirements and security policies
+   - **Key Pattern**: Apply the EventuallyWithT pattern correctly for all external calls as documented above
+
+4. **Root Cause Analysis**: Distinguish between actual code regressions (route approval logic, HA failover architecture), timing issues requiring `EventuallyWithT` patterns, and genuine infrastructure problems (DNS, Docker, container issues).
+   - **Why this distinction matters**: Different problem types require completely different solution approaches
+   - **EventuallyWithT Issues**: Often manifest as flaky tests or immediate assertion failures after async operations
+
+5. **Security-Aware Quality Validation**: Ensure tests properly validate end-to-end functionality with realistic timing expectations and proper error handling. Never suggest security bypasses or test expectation changes. Add comprehensive godoc when you understand test business logic.
+   - **Why security focus**: Integration tests are the last line of defense against security regressions
+   - **EventuallyWithT Usage**: Proper use prevents race conditions without weakening security assertions
+
+6. **Concurrent Execution Awareness**: Respect run ID isolation and never interfere with other agents' test sessions. Each test run has a unique run ID - only clean up YOUR containers (by run ID label), never perform global cleanup while tests may be running.
+   - **Why this matters**: Multiple agents/users may run tests concurrently on the same Docker daemon
+   - **Key Rule**: NEVER use global container cleanup commands - the test runner handles cleanup automatically per run ID
+
+**CRITICAL PRINCIPLE**: Test expectations are sacred contracts that define correct system behavior. When tests fail, fix the code to match the test, never change the test to match broken code. Only timing and observability improvements are allowed - business logic expectations are immutable.
+
+**ISOLATION PRINCIPLE**: Each test run is isolated by its unique Run ID. Never interfere with other test sessions. The system handles cleanup automatically - manual global cleanup commands are forbidden when other tests may be running.
+
+**EventuallyWithT PRINCIPLE**: Every external call to headscale server or tailscale client must be wrapped in EventuallyWithT. Follow the five key rules strictly: one external call per block, proper variable scoping, no nesting, use CollectT for assertions, and provide descriptive messages.
+
+**Remember**: Test failures are usually code issues in Headscale that need to be fixed, not infrastructure problems to be ignored. Use the specific debugging workflows and failure patterns documented above to efficiently identify root causes. Infrastructure issues have very specific signatures - everything else is code-related.

-Thank you for taking the time to report this issue.
-
-To help us investigate and resolve this, we need more information. Please provide the following:
-
-> [!TIP]
-> Most issues turn out to be configuration errors rather than bugs. We encourage you to discuss your problem in our [Discord community](https://discord.gg/c84AZQhmpx) **before** opening an issue. The community can often help identify misconfigurations quickly, saving everyone time.
-
-## Required Information
-
-### Environment Details
-
-- **Headscale version**: (run `headscale version`)
-- **Tailscale client version**: (run `tailscale version`)
-- **Operating System**: (e.g., Ubuntu 24.04, macOS 14, Windows 11)
-- **Deployment method**: (binary, Docker, Kubernetes, etc.)
-- **Reverse proxy**: (if applicable: nginx, Traefik, Caddy, etc. - include configuration)
-
-### Debug Information
-
-Please follow our [Debugging and Troubleshooting Guide](https://headscale.net/stable/ref/debug/) and provide:
-
-1. **Client netmap dump** (from affected Tailscale client):
-
-   ```bash
-   tailscale debug netmap > netmap.json
-   ```
-
-2. **Client status dump** (from affected Tailscale client):
-
-   ```bash
-   tailscale status --json > status.json
-   ```
-
-3. **Tailscale client logs** (if experiencing client issues):
-
-   ```bash
-   tailscale debug daemon-logs
-   ```
-
-   > [!IMPORTANT]
-   > We need logs from **multiple nodes** to understand the full picture:
-   >
-   > - The node(s) initiating connections
-   > - The node(s) being connected to
-   >
-   > Without logs from both sides, we cannot diagnose connectivity issues.
-
-4. **Headscale server logs** with `log.level: trace` enabled
-
-5. **Headscale configuration** (with sensitive values redacted - see rules below)
-
-6. **ACL/Policy configuration** (if using ACLs)
-
-7. **Proxy/Docker configuration** (if applicable - nginx.conf, docker-compose.yml, Traefik config, etc.)
-
-## Formatting Requirements
-
-- **Attach long files** - Do not paste large logs or configurations inline. Use GitHub file attachments or GitHub Gists.
-- **Use proper Markdown** - Format code blocks, logs, and configurations with appropriate syntax highlighting.
-- **Structure your response** - Use the headings above to organize your information clearly.
-
-## Redaction Rules
-
-> [!CAUTION]
-> **Replace, do not remove.** Removing information makes debugging impossible.
-
-When redacting sensitive information:
-
-- ✅ **Replace consistently** - If you change `alice@company.com` to `user1@example.com`, use `user1@example.com` everywhere (logs, config, policy, etc.)
-- ✅ **Use meaningful placeholders** - `user1@example.com`, `bob@example.com`, `my-secret-key` are acceptable
-- ❌ **Never remove information** - Gaps in data prevent us from correlating events across logs
-- ❌ **Never redact IP addresses** - We need the actual IPs to trace network paths and identify issues
-
-**If redaction rules are not followed, we will be unable to debug the issue and will have to close it.**

 # CHANGELOG
 
-## 0.29.0 (202x-xx-xx)
-
-**Minimum supported Tailscale client version: v1.76.0**
-
-### Tailscale ACL compatibility improvements
-
-Extensive test cases were systematically generated using Tailscale clients and the official SaaS
-to understand how the packet filter should be generated. We discovered a few differences, but
-overall our implementation was very close.
-[#3036](https://github.com/juanfont/headscale/pull/3036)
-
-### SSH check action
-
-SSH rules with `"action": "check"` are now supported. When a client initiates a SSH connection to a node
-with a `check` action policy, the user is prompted to authenticate via OIDC or CLI approval before access
-is granted. OIDC approval requires the authenticated user to own the source node; tagged source nodes
-cannot use SSH check-mode.
-
-A new `headscale auth` CLI command group supports the approval flow:
-
-- `headscale auth approve --auth-id <id>` approves a pending authentication request (SSH check or web auth)
-- `headscale auth reject --auth-id <id>` rejects a pending authentication request
-- `headscale auth register --auth-id <id> --user <user>` registers a node (replaces deprecated `headscale nodes register`)
-
-[#1850](https://github.com/juanfont/headscale/pull/1850)
-[#3180](https://github.com/juanfont/headscale/pull/3180)
-
-### Grants
-
-We now support [Tailscale grants](https://tailscale.com/kb/1324/grants) alongside ACLs. Grants
-extend what you can express in a policy beyond packet filtering: the `app` field controls
-application-level features like Taildrive file sharing and peer relay, and the `via` field steers
-traffic through specific tagged subnet routers or exit nodes. The `ip` field works like an ACL rule.
-Grants can be mixed with ACLs in the same policy file.
-[#2180](https://github.com/juanfont/headscale/pull/2180)
-
-As part of this, we added `autogroup:danger-all`. It resolves to `0.0.0.0/0` and `::/0` — all IP
-addresses, including those outside the tailnet. This replaces the old behaviour where `*` matched
-all IPs (see BREAKING below). The name is intentionally scary: accepting traffic from the entire
-internet is a security-sensitive choice. `autogroup:danger-all` can only be used as a source.
-
-### BREAKING
-
-- **ACL Policy**: Wildcard (`*`) in ACL sources and destinations now resolves to Tailscale's CGNAT range (`100.64.0.0/10`) and ULA range (`fd7a:115c:a1e0::/48`) instead of all IPs (`0.0.0.0/0` and `::/0`) [#3036](https://github.com/juanfont/headscale/pull/3036)
-  - This better matches Tailscale's security model where `*` means "any node in the tailnet" rather than "any IP address"
-  - Policies that need to match all IP addresses including non-Tailscale IPs should use `autogroup:danger-all` as a source, or explicit CIDR ranges as destinations [#2180](https://github.com/juanfont/headscale/pull/2180)
-  - `autogroup:danger-all` can only be used as a source; it cannot be used as a destination
-  - **Note**: Users with non-standard IP ranges configured in `prefixes.ipv4` or `prefixes.ipv6` (which is unsupported and produces a warning) will need to explicitly specify their CIDR ranges in ACL rules instead of using `*`
-- **ACL Policy**: Validate autogroup:self source restrictions matching Tailscale behavior - tags, hosts, and IPs are rejected as sources for autogroup:self destinations [#3036](https://github.com/juanfont/headscale/pull/3036)
-  - Policies using tags, hosts, or IP addresses as sources for autogroup:self destinations will now fail validation
-- **Upgrade path**: Headscale now enforces a strict version upgrade path [#3083](https://github.com/juanfont/headscale/pull/3083)
-  - Skipping minor versions (e.g. 0.27 → 0.29) is blocked; upgrade one minor version at a time
-  - Downgrading to a previous minor version is blocked
-  - Patch version changes within the same minor are always allowed
-- **ACL Policy**: The `proto:icmp` protocol name now only includes ICMPv4 (protocol 1), matching Tailscale behavior [#3036](https://github.com/juanfont/headscale/pull/3036)
-  - Previously, `proto:icmp` included both ICMPv4 and ICMPv6
-  - Use `proto:ipv6-icmp` or protocol number `58` explicitly for ICMPv6
-- **CLI**: `headscale nodes register` is deprecated in favour of `headscale auth register --auth-id <id> --user <user>` [#1850](https://github.com/juanfont/headscale/pull/1850)
-  - The old command continues to work but will be removed in a future release
-
-### Changes
-
-- **OIDC registration**: Add a confirmation page before completing node registration, showing the device hostname and machine key fingerprint [#3180](https://github.com/juanfont/headscale/pull/3180)
-- **Debug endpoints**: Omit secret fields (`Pass`, `ClientSecret`, `APIKey`) from `/debug/config` JSON output [#3180](https://github.com/juanfont/headscale/pull/3180)
-- **Debug endpoints**: Route `statsviz` through `tsweb.Protected` [#3180](https://github.com/juanfont/headscale/pull/3180)
-- Remove gRPC reflection from the remote (TCP) server [#3180](https://github.com/juanfont/headscale/pull/3180)
-- **Node Expiry**: Add `node.expiry` configuration option to set a default node key expiry for nodes registered via auth key [#3122](https://github.com/juanfont/headscale/pull/3122)
-  - Tagged nodes (registered with tagged pre-auth keys) are exempt from default expiry
-  - `oidc.expiry` has been removed; use `node.expiry` instead (applies to all registration methods including OIDC)
-  - `ephemeral_node_inactivity_timeout` is deprecated in favour of `node.ephemeral.inactivity_timeout`
-- **SSH Policy**: Add support for `localpart:*@<domain>` in SSH rule `users` field, mapping each matching user's email local-part as their OS username [#3091](https://github.com/juanfont/headscale/pull/3091)
-- **ACL Policy**: Add ICMP and IPv6-ICMP protocols to default filter rules when no protocol is specified [#3036](https://github.com/juanfont/headscale/pull/3036)
-- **ACL Policy**: Fix autogroup:self handling for tagged nodes - tagged nodes no longer incorrectly receive autogroup:self filter rules [#3036](https://github.com/juanfont/headscale/pull/3036)
-- **ACL Policy**: Use CIDR format for autogroup:self destination IPs matching Tailscale behavior [#3036](https://github.com/juanfont/headscale/pull/3036)
-- **ACL Policy**: Merge filter rules with identical SrcIPs and IPProto matching Tailscale behavior - multiple ACL rules with the same source now produce a single FilterRule with combined DstPorts [#3036](https://github.com/juanfont/headscale/pull/3036)
-- Remove deprecated `--namespace` flag from `nodes list`, `nodes register`, and `debug create-node` commands (use `--user` instead) [#3093](https://github.com/juanfont/headscale/pull/3093)
-- Remove deprecated `namespace`/`ns` command aliases for `users` and `machine`/`machines` aliases for `nodes` [#3093](https://github.com/juanfont/headscale/pull/3093)
-- Add SSH `check` action support with OIDC and CLI-based approval flows [#1850](https://github.com/juanfont/headscale/pull/1850)
-- Add `headscale auth register`, `headscale auth approve`, and `headscale auth reject` CLI commands [#1850](https://github.com/juanfont/headscale/pull/1850)
-- Add `auth` related routes to the API. The `auth/register` endpoint now expects data as JSON [#1850](https://github.com/juanfont/headscale/pull/1850)
-- Deprecate `headscale nodes register --key` in favour of `headscale auth register --auth-id` [#1850](https://github.com/juanfont/headscale/pull/1850)
-- Generalise auth templates into reusable `AuthSuccess` and `AuthWeb` components [#1850](https://github.com/juanfont/headscale/pull/1850)
-- Unify auth pipeline with `AuthVerdict` type, supporting registration, reauthentication, and SSH checks [#1850](https://github.com/juanfont/headscale/pull/1850)
-- Add support for policy grants with `ip`, `app`, and `via` fields [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Add `autogroup:danger-all` as a source-only autogroup resolving to all IP addresses [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Add capability grants for Taildrive (`cap/drive`) and peer relay (`cap/relay`) with automatic companion capabilities [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Add per-viewer via route steering — grants with `via` tags control which subnet router or exit node handles traffic for each group of viewers [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Enable Taildrive node attributes on all nodes; actual access is controlled by `cap/drive` grants [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Fix exit nodes incorrectly receiving filter rules for destinations that only overlap via exit routes [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Fix address-based aliases (hosts, raw IPs) incorrectly expanding to include the matching node's other address family [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Fix identity-based aliases (tags, users, groups) resolving to IPv4 only; they now include both IPv4 and IPv6 matching Tailscale behavior [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Fix wildcard (`*`) source in ACLs now using actually-approved subnet routes instead of autoApprover policy prefixes [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Fix non-wildcard source IPs being dropped when combined with wildcard `*` in the same ACL rule [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Fix exit node approval not triggering filter rule recalculation for peers [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Policy validation error messages now include field context (e.g., `src=`, `dst=`) and are more descriptive [#2180](https://github.com/juanfont/headscale/pull/2180)
-- Remove old migrations for the debian package [#3185](https://github.com/juanfont/headscale/pull/3185)

-# hi — Headscale Integration test runner
+# hi
 
-`hi` wraps Docker container orchestration around the tests in
-[`../../integration`](../../integration) and extracts debugging artefacts
-(logs, database snapshots, MapResponse protocol captures) for post-mortem
-analysis.
-
-**Read this file in full before running any `hi` command.** The test
-runner has sharp edges — wrong flags produce stale containers, lost
-artefacts, or hung CI.
-
-For test-authoring patterns (scenario setup, `EventuallyWithT`,
-`IntegrationSkip`, helper variants), read
-[`../../integration/README.md`](../../integration/README.md).
-
-## Quick Start
-
-```bash
-# Verify system requirements (Docker, Go, disk space, images)
-go run ./cmd/hi doctor
-
-# Run a single test (the default flags are tuned for development)
-go run ./cmd/hi run "TestPingAllByIP"
-
-# Run a database-heavy test against PostgreSQL
-go run ./cmd/hi run "TestExpireNode" --postgres
-
-# Pattern matching
-go run ./cmd/hi run "TestSubnet*"
-```
-
-Run `doctor` before the first `run` in any new environment. Tests
-generate ~100 MB of logs per run in `control_logs/`; `doctor` verifies
-there is enough space and that the required Docker images are available.

-
-### Timeout guidance
-
-The default `120m` is generous for a single test. If you must tune it,
-these are realistic floors by category:
-
-| Test type                 | Minimum     | Examples                              |
-| ------------------------- | ----------- | ------------------------------------- |
-| Basic functionality / CLI | 900s (15m)  | `TestPingAllByIP`, `TestCLI*`         |
-| Route / ACL               | 1200s (20m) | `TestSubnet*`, `TestACL*`             |
-| HA / failover             | 1800s (30m) | `TestHASubnetRouter*`                 |
-| Long-running              | 2100s (35m) | `TestNodeOnlineStatus` (~12 min body) |
-| Full suite                | 45m         | `go test ./integration -timeout 45m`  |
-
-**Never** use the shell `timeout` command around `hi`. It kills the
-process mid-cleanup and leaves stale containers:
-
-```bash
-timeout 300 go run ./cmd/hi run "TestName"   # WRONG — orphaned containers
-go run ./cmd/hi run "TestName" --timeout=900s  # correct
-```
-
-## Concurrent Execution
-
-Multiple `hi run` invocations can run simultaneously on the same Docker
-daemon. Each invocation gets a unique **Run ID** (format
-`YYYYMMDD-HHMMSS-6charhash`, e.g. `20260409-104215-mdjtzx`).
-
-- **Container names** include the short run ID: `ts-mdjtzx-1-74-fgdyls`
-- **Docker labels**: `hi.run-id={runID}` on every container
-- **Port allocation**: dynamic — kernel assigns free ports, no conflicts
-- **Cleanup isolation**: each run cleans only its own containers
-- **Log directories**: `control_logs/{runID}/`
-
-```bash
-# Start three tests in parallel — each gets its own run ID
-go run ./cmd/hi run "TestPingAllByIP" &
-go run ./cmd/hi run "TestACLAllowUserDst" &
-go run ./cmd/hi run "TestOIDCAuthenticationPingAll" &
-```
-
-### Safety rules for concurrent runs
-
-- ✅ Your run cleans only containers labelled with its own `hi.run-id`
-- ✅ `--clean-before` removes only stopped/exited containers
-- ❌ **Never** run `docker rm -f $(docker ps -q --filter name=hs-)` —
-  this destroys other agents' live test sessions
-- ❌ **Never** run `docker system prune -f` while any tests are running
-- ❌ **Never** run `hi clean containers` / `hi clean all` while other
-  tests are running — both kill all test containers on the daemon
-
-To identify your own containers:
-
-```bash
-docker ps --filter "label=hi.run-id=20260409-104215-mdjtzx"
-```
-
-The run ID appears at the top of the `hi run` output — copy it from
-there rather than trying to reconstruct it.
-
-## Artefacts
-
-Every run saves debugging artefacts under `control_logs/{runID}/`:
-
-```
-control_logs/20260409-104215-mdjtzx/
-├── hs-<test>-<hash>.stderr.log        # headscale server errors
-├── hs-<test>-<hash>.stdout.log        # headscale server output
-├── hs-<test>-<hash>.db                # database snapshot (SQLite)
-├── hs-<test>-<hash>_metrics.txt       # Prometheus metrics dump
-├── hs-<test>-<hash>-mapresponses/     # MapResponse protocol captures
-├── ts-<client>-<hash>.stderr.log      # tailscale client errors
-├── ts-<client>-<hash>.stdout.log      # tailscale client output
-└── ts-<client>-<hash>_status.json     # client network-status dump
-```
-
-Artefacts persist after cleanup. Old runs accumulate fast — delete
-unwanted directories to reclaim disk.
-
-## Debugging workflow
-
-When a test fails, read the artefacts **in this order**:
-
-1. **`hs-*.stderr.log`** — headscale server errors, panics, policy
-   evaluation failures. Most issues originate server-side.
-
-   ```bash
-   grep -E "ERROR|panic|FATAL" control_logs/*/hs-*.stderr.log
-   ```
-
-2. **`ts-*.stderr.log`** — authentication failures, connectivity issues,
-   DNS resolution problems on the client side.
-
-3. **MapResponse JSON** in `hs-*-mapresponses/` — protocol-level
-   debugging for network map generation, peer visibility, route
-   distribution, policy evaluation results.
-
-   ```bash
-   ls control_logs/*/hs-*-mapresponses/
-   jq '.Peers[] | {Name, Tags, PrimaryRoutes}' \
-       control_logs/*/hs-*-mapresponses/001.json
-   ```
-
-4. **`*_status.json`** — client peer-connectivity state.
-
-5. **`hs-*.db`** — SQLite snapshot for post-mortem consistency checks.
-
-   ```bash
-   sqlite3 control_logs/<runID>/hs-*.db
-   sqlite> .tables
-   sqlite> .schema nodes
-   sqlite> SELECT id, hostname, user_id, tags FROM nodes WHERE hostname LIKE '%problematic%';
-   ```
-
-6. **`*_metrics.txt`** — Prometheus dumps for latency, NodeStore
-   operation timing, database query performance, memory usage.
-
-## Heuristic: infrastructure vs code
-
-**Before blaming Docker, disk, or network: read `hs-*.stderr.log` in
-full.** In practice, well over 99% of failures are code bugs (policy
-evaluation, NodeStore sync, route approval) rather than infrastructure.
-
-Actual infrastructure failures have signature error messages:
-
-| Signature                                                       | Cause                     | Fix                                                           |
-| --------------------------------------------------------------- | ------------------------- | ------------------------------------------------------------- |
-| `failed to resolve "hs-...": no DNS fallback candidates remain` | Docker DNS                | Reset Docker networking                                       |
-| `container creation timeout`, no progress >2 min                | Resource exhaustion       | `docker system prune -f` (when no other tests running), retry |
-| OOM kills, slow Docker daemon                                   | Too many concurrent tests | Reduce concurrency, wait for completion                       |
-| `no space left on device`                                       | Disk full                 | Delete old `control_logs/`                                    |
-
-If you don't see a signature error, **assume it's a code regression** —
-do not retry hoping the flake goes away.
-
-## Common failure patterns (code bugs)
-
-### Route advertisement timing
-
-Test asserts route state before the client has finished propagating its
-Hostinfo update. Symptom: `nodes[0].GetAvailableRoutes()` empty when
-the test expects a route.
-
-- **Wrong fix**: `time.Sleep(5 * time.Second)` — fragile and slow.
-- **Right fix**: wrap the assertion in `EventuallyWithT`. See
-  [`../../integration/README.md`](../../integration/README.md).
-
-### NodeStore sync issues
-
-Route changes not reflected in the NodeStore snapshot. Symptom: route
-advertisements in logs but no tracking updates in subsequent reads.
-
-The sync point is `State.UpdateNodeFromMapRequest()` in
-`hscontrol/state/state.go`. If you added a new kind of client state
-update, make sure it lands here.
-
-### HA failover: routes disappearing on disconnect
-
-`TestHASubnetRouterFailover` fails because approved routes vanish when
-a subnet router goes offline. **This is a bug, not expected behaviour.**
-Route approval must not be coupled to client connectivity — routes
-stay approved; only the primary-route selection is affected by
-connectivity.
-
-### Policy evaluation race
-
-Symptom: tests that change policy and immediately assert peer visibility
-fail intermittently. Policy changes trigger async recomputation.
-
-- See recent fixes in `git log -- hscontrol/state/` for examples (e.g.
-  the `PolicyChange` trigger on every Connect/Disconnect).
-
-### SQLite vs PostgreSQL timing differences
-
-Some race conditions only surface on one backend. If a test is flaky,
-try the other backend with `--postgres`:
-
-```bash
-go run ./cmd/hi run "TestName" --postgres --verbose
-```
-
-PostgreSQL generally has more consistent timing; SQLite can expose
-races during rapid writes.
-
-## Keeping containers for inspection
-
-If you need to inspect a failed test's state manually:
-
-```bash
-go run ./cmd/hi run "TestName" --keep-on-failure
-# containers survive — inspect them
-docker exec -it ts-<runID>-<...> /bin/sh
-docker logs hs-<runID>-<...>
-# clean up manually when done
-go run ./cmd/hi clean all   # only when no other tests are running
-```
+hi (headscale integration runner) is an entirely "vibe coded" wrapper around our
+[integration test suite](../integration). It essentially runs the docker
+commands for you with some added benefits of extracting resources like logs and
+databases.

-## Switching OIDC providers
-
-Headscale only supports a single OIDC provider in its configuration, but it does store the provider identifier of each user. When switching providers, this might lead to issues with existing users: all user details (name, email, groups) might be identical with the new provider, but the identifier will differ. Headscale will be unable to create a new user as the name and email will already be in use for the existing users.
-
-At this time, you will need to manually update the `provider_identifier` column in the `users` table for each user with the appropriate value for the new provider. The identifier is built from the `iss` and `sub` claims of the OIDC ID token, for example `https://id.example.com/12340987`.

-# Registration methods
-
-Headscale supports multiple ways to register a node. The preferred registration method depends on the identity of a node
-and your use case.
-
-## Identity model
-
-Tailscale's identity model distinguishes between personal and tagged nodes:
-
-- A personal node (or user-owned node) is owned by a human and typically refers to end-user devices such as laptops,
-  workstations or mobile phones. End-user devices are managed by a single user.
-- A tagged node (or service-based node or non-human node) provides services to the network. Common examples include web-
-  and database servers. Those nodes are typically managed by a team of users. Some additional restrictions apply for
-  tagged nodes, e.g. a tagged node is not allowed to [Tailscale SSH](https://tailscale.com/kb/1193/tailscale-ssh) into a
-  personal node.
-
-Headscale implements Tailscale's identity model and distinguishes between personal and tagged nodes where a personal
-node is owned by a Headscale user and a tagged node is owned by a tag. Tagged devices are grouped under the special user
-`tagged-devices`.
-
-## Registration methods
-
-There are two main ways to register new nodes, [web authentication](#web-authentication) and [registration with a pre
-authenticated key](#pre-authenticated-key). Both methods can be used to register personal and tagged nodes.
-
-### Web authentication
-
-Web authentication is the default method to register a new node. It's interactive, where the client initiates the
-registration and the Headscale administrator needs to approve the new node before it is allowed to join the network. A
-node can be approved with:
-
-- Headscale CLI (described in this documentation)
-- [Headscale API](api.md)
-- Or delegated to an identity provider via [OpenID Connect](oidc.md)
-
-Web authentication relies on the presence of a Headscale user. Use the `headscale users` command to create a new
-user[^1]:
-
-```console
-headscale users create <USER>
-```
-
-=== "Personal devices"
-
-    Run `tailscale up` to login your personal device:
-
-    ```console
-    tailscale up --login-server <YOUR_HEADSCALE_URL>
-    ```
-
-    Usually, a browser window with further instructions is opened. This page explains how to complete the registration
-    on your Headscale server and it also prints the Auth ID required to approve the node:
-
-    ```console
-    headscale auth register --user <USER> --auth-id <AUTH_ID>
-    ```
-
-    Congrations, the registration of your personal node is complete and it should be listed as "online" in the output of
-    `headscale nodes list`. The "User" column displays `<USER>` as the owner of the node.
-
-=== "Tagged devices"
-
-    Your Headscale user needs to be authorized to register tagged devices. This authorization is specified in the
-    [`tagOwners`](https://tailscale.com/kb/1337/policy-syntax#tag-owners) section of the [ACL](acls.md). A simple
-    example looks like this:
-
-    ```json title="The user alice can register nodes tagged with tag:server"
-    {
-      "tagOwners": {
-        "tag:server": ["alice@"]
-      },
-      // more rules
-    }
-    ```
-
-    Run `tailscale up` and provide at least one tag to login a tagged device:
-
-    ```console
-    tailscale up --login-server <YOUR_HEADSCALE_URL> --advertise-tags tag:<TAG>
-    ```
-
-    Usually, a browser window with further instructions is opened. This page explains how to complete the registration
-    on your Headscale server and it also prints the Auth ID required to approve the node:
-
-    ```console
-    headscale auth register --user <USER> --auth-id <AUTH_ID>
-    ```
-
-    Headscale checks that `<USER>` is allowed to register a node with the specified tag(s) and then transfers ownership
-    of the new node to the special user `tagged-devices`. The registration of a tagged node is complete and it should be
-    listed as "online" in the output of `headscale nodes list`. The "User" column displays `tagged-devices` as the owner
-    of the node. See the "Tags" column for the list of assigned tags.
-
-### Pre authenticated key
-
-Registration with a pre authenticated key (or auth key) is a non-interactive way to register a new node. The Headscale
-administrator creates a preauthkey upfront and this preauthkey can then be used to register a node non-interactively.
-Its best suited for automation.
-
-=== "Personal devices"
-
-    A personal node is always assigned to a Headscale user. Use the `headscale users` command to create a new user[^1]:
-
-    ```console
-    headscale users create <USER>
-    ```
-
-    Use the `headscale user list` command to learn its `<USER_ID>` and create a new pre authenticated key for your user:
-
-    ```console
-    headscale preauthkeys create --user <USER_ID>
-    ```
-
-    The above prints a pre authenticated key with the default settings (can be used once and is valid for one hour). Use
-    this auth key to register a node non-interactively:
-
-    ```console
-    tailscale up --login-server <YOUR_HEADSCALE_URL> --authkey <YOUR_AUTH_KEY>
-    ```
-
-    Congrations, the registration of your personal node is complete and it should be listed as "online" in the output of
-    `headscale nodes list`. The "User" column displays `<USER>` as the owner of the node.
-
-=== "Tagged devices"
-
-    Create a new pre authenticated key and provide at least one tag:
-
-    ```console
-    headscale preauthkeys create --tags tag:<TAG>
-    ```
-
-    The above prints a pre authenticated key with the default settings (can be used once and is valid for one hour). Use
-    this auth key to register a node non-interactively. You don't need to provide the `--advertise-tags` parameter as
-    the tags are automatically read from the pre authenticated key:
-
-    ```console
-    tailscale up --login-server <YOUR_HEADSCALE_URL> --authkey <YOUR_AUTH_KEY>
-    ```
-
-    The registration of a tagged node is complete and it should be listed as "online" in the output of
-    `headscale nodes list`. The "User" column displays `tagged-devices` as the owner of the node. See the "Tags" column for the list of
-    assigned tags.

-# Tags
-
-Headscale supports Tailscale tags. Please read [Tailscale's tag documentation](https://tailscale.com/kb/1068/tags) to
-learn how tags work and how to use them.
-
-Tags can be applied during [node registration](registration.md):
-
-- using the `--advertise-tags` flag, see [web authentication for tagged devices](registration.md#__tabbed_1_2)
-- using a tagged pre authenticated key, see [how to create and use it](registration.md#__tabbed_2_2)
-
-Administrators can manage tags with:
-
-- Headscale CLI
-- [Headscale API](api.md)
-
-## Common operations
-
-### Manage tags for a node
-
-Run `headscale nodes list` to list the tags for a node.
-
-Use the `headscale nodes tag` command to modify the tags for a node. At least one tag is required and multiple tags can
-be provided as comma separated list. The following command sets the tags `tag:server` and `tag:prod` on node with ID 1:
-
-```console
-headscale nodes tag -i 1 -t tag:server,tag:prod
-```
-
-### Convert from personal to tagged node
-
-Use the `headscale nodes tag` command to convert a personal (user-owned) node to a tagged node:
-
-```console
-headscale nodes tag -i <NODE_ID> -t <TAG>
-```
-
-The node is now owned by the special user `tagged-devices` and has the specified tags assigned to it.
-
-### Convert from tagged to personal node
-
-Tagged nodes can return to personal (user-owned) nodes by re-authenticating with:
-
-```console
-tailscale up --login-server <YOUR_HEADSCALE_URL> --advertise-tags= --force-reauth
-```
-
-Usually, a browser window with further instructions is opened. This page explains how to complete the registration on
-your Headscale server and it also prints the Auth ID required to approve the node:
-
-```console
-headscale auth register --user <USER> --auth-id <AUTH_ID>
-```
-
-All previously assigned tags get removed and the node is now owned by the user specified in the above command.

-
-## Backup
-
-Headscale applies database migrations during upgrades and we highly recommend to create a backup of your database before
-upgrading. A full backup of Headscale depends on your individual setup, but below are some typical setup scenarios.
-
-=== "Standard installation"
-
-    A installation that follows our [official releases](install/official.md) setup guide uses the following paths:
-
-    - [Configuration file](../ref/configuration.md): `/etc/headscale/config.yaml`
-    - Data directory: `/var/lib/headscale`
-    - SQLite as database: `/var/lib/headscale/db.sqlite`
-
-    ```console
-    TIMESTAMP=$(date +%Y%m%d%H%M%S)
-    cp -aR /etc/headscale /etc/headscale.backup-$TIMESTAMP
-    cp -aR /var/lib/headscale /var/lib/headscale.backup-$TIMESTAMP
-    ```
-
-=== "Container"
-
-    A installation that follows our [container](install/container.md) setup guide uses a single source volume directory
-    that contains the configuration file, data directory and the SQLite database.
-
-    ```console
-    cp -aR /path/to/headscale /path/to/headscale.backup-$(date +%Y%m%d%H%M%S)
-    ```
-
-=== "PostgreSQL"
-
-    Please follow PostgreSQL's [Backup and Restore](https://www.postgresql.org/docs/current/backup.html) documentation
-    to create a backup of your PostgreSQL database.
