-name: headscale-integration-tester
-description: Use this agent when you need to execute, analyze, or troubleshoot Headscale integration tests. 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
-    for _, peerKey := range status.Peers() {
-        peerStatus := status.Peer[peerKey]
-        requirePeerSubnetRoutesWithCollect(c, peerStatus, expectedPrefixes)
-    }
-}, 10*time.Second, 500*time.Millisecond, "client should see expected routes")
-
-// CORRECT: Variable scoping for sharing between blocks
-var routeNode *v1.Node
-var nodeKey key.NodePublic
-
-// First EventuallyWithT to get the node

-### 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.

+### v1 REST API replaced; gRPC and Protobuf removed
+
+The v1 REST API now provides an OpenAPI 3.1 specification at
+`/api/v1/openapi.yaml`, with interactive documentation at `/api/v1/docs`. This
+replaces the Swagger 2.0 document and the `/swagger` UI. The Protobuf, gRPC and
+grpc-gateway stack behind it is gone, and the `headscale` CLI now talks to the
+HTTP API directly.
+
+[#3324](https://github.com/juanfont/headscale/pull/3324)
+
+### OAuth clients and scopes for the v2 API
+
+The v2 API now authenticates with OAuth 2.0 client-credentials, the way the
+Tailscale ecosystem does. An OAuth client mints short-lived access tokens whose
+scopes limit which operations they may perform and whose tags limit the devices
+they may create, so a credential can be issued with only the access it needs.
+The `headscale oauth-clients` command manages them. This lets the Tailscale
+Terraform provider and Kubernetes operator drive Headscale unchanged; admin API
+keys remain all-access.
+
+[#3334](https://github.com/juanfont/headscale/pull/3334)
+
+### BREAKING
+
+#### API
+
+- The gRPC API is removed; all programmatic access now goes through the HTTP API at `/api/v1` [#3324](https://github.com/juanfont/headscale/pull/3324)
+- API errors are now RFC 7807 `application/problem+json`, including authentication failures, instead of the previous gRPC-status JSON shape [#3324](https://github.com/juanfont/headscale/pull/3324)
+- Errors that previously returned HTTP 500 — unknown users or nodes, malformed input, duplicate names — now return the correct 404, 400 or 409 [#3324](https://github.com/juanfont/headscale/pull/3324)
+- The OpenAPI document is OpenAPI 3.1 at `/api/v1/openapi.yaml` (docs at `/api/v1/docs`), replacing Swagger 2.0 at `/swagger` [#3324](https://github.com/juanfont/headscale/pull/3324)
+
+#### CLI
+
+- `--output json` / `--output yaml` now emit the API's shape — camelCase fields, string-encoded IDs, RFC3339 timestamps — instead of the old Protobuf encoding [#3324](https://github.com/juanfont/headscale/pull/3324)
+- `headscale policy` renames the database-bypass flag from `--bypass-grpc-and-access-database-directly` to `--bypass-server-and-access-database-directly` [#3324](https://github.com/juanfont/headscale/pull/3324)
+
+### Changes
+
+- Expiring or deleting a non-existent pre-auth key now returns an error instead of silently succeeding [#3324](https://github.com/juanfont/headscale/pull/3324)
+- Improve systemd service file hardening [#3341](https://github.com/juanfont/headscale/pull/3341)
+
+## 0.29.2 (2026-07-01)
+
+**Minimum supported Tailscale client version: v1.80.0**
+
+### Changes
+
+- Fix map generation serializing on the policy lock, so a mass reconnect on `autogroup:self`, via or relay policies no longer stalls clients into `unexpected EOF` retry loops [#3358](https://github.com/juanfont/headscale/pull/3358)
+- Fix `/ts2021` rejecting the WebSocket `GET` upgrade with 405, which prevented Tailscale JS/WASM control clients from connecting [#3359](https://github.com/juanfont/headscale/pull/3359)
+- Gracefully handle nodes with an invalid FQDN (empty or too long) instead of failing map delivery; offending names are logged at startup with the fix command [#3349](https://github.com/juanfont/headscale/pull/3349)

+### Policy tests (beta)
+
+Headscale now evaluates the `tests` block in a policy file. Tests assert reachability between
+named sources and destinations and cover the whole policy — both `acls` and `grants` rules
+contribute. They run on user-initiated writes via `headscale policy set`, on SIGHUP reload
+(`systemctl reload headscale` / `kill -HUP $(pidof headscale)`), and on `headscale policy check`.
+A failing test rejects the write before it is applied, with the same error message Tailscale SaaS
+would return for the same policy.
+
+At boot a stored policy whose tests no longer pass — for example because a referenced user was
+deleted while the server was offline — logs a warning and the server keeps running. Fix the
+policy and reload.
+
+This feature is **beta** while behavioural coverage against Tailscale SaaS broadens.
+
+[#3229](https://github.com/juanfont/headscale/pull/3229)
+
+### SSH policy tests (beta)
+
+Headscale now evaluates the `sshTests` block in a policy file. Each entry names a source, one or
+more destination hosts, and three optional user lists: `accept` asserts the listed login users
+reach every destination via an accept- or check-action SSH rule, `deny` asserts none of them
+reach any destination, and `check` requires reachability specifically through a check-action
+rule. Tests run on `headscale policy set`, on SIGHUP reload (`systemctl reload headscale` /
+`kill -HUP $(pidof headscale)`), and on `headscale policy check`. A failing test rejects the
+write before it is applied, with the same error message Tailscale SaaS would return for the same
+policy.

+### SSH rule validation
+
+SSH rule parsing now trims surrounding whitespace on `action`, `users`, `src`, and `dst`,
+rejects empty or wildcard entries in `users`, rejects empty `acceptEnv`, and rejects negative
+`checkPeriod`. `hosts:` aliases are rejected as SSH destinations, non-ASCII tag names are
+rejected at parse time, and the wording for group-nesting cycles matches Tailscale SaaS.

+all IPs (see BREAKING below). The name is intentional: accepting traffic from the entire
 internet is a security-sensitive choice. `autogroup:danger-all` can only be used as a source.
 
+### Node attributes (`nodeAttrs`)
+
+ACL policies now accept a `nodeAttrs` block. Each entry hands a list of
+Tailscale node capabilities to every node matching `target`. The accepted
+target forms are the same as `acls.src` and `grants.src`: users, groups,
+tags, hosts, prefixes, `autogroup:member`, `autogroup:tagged`, and `*`.
+
+```jsonc
+{
+  "randomizeClientPort": true,
+  "nodeAttrs": [
+    { "target": ["autogroup:tagged"], "attr": ["disable-captive-portal-detection"] },
+    { "target": ["alice@example.com"], "attr": ["nextdns:abc123"] },
+  ],
+}
+```
+
+Frequently requested capabilities this unlocks include `magicdns-aaaa`,
+`disable-relay-server`, `disable-captive-portal-detection`,
+`nextdns:<profile>` / `nextdns:no-device-info`, `randomize-client-port`,
+and the Taildrive `drive:share` / `drive:access` pair. The set is not
+limited to these, any string-only cap an operator places in policy
+reaches clients unchanged.
+
+`randomizeClientPort` also lands as a top-level policy field that toggles
+the default for every node, replacing the old server-config knob.
+
+A new `auto_update.enabled` config option controls the tailnet-wide
+default for client auto-update. When true, every node's CapMap carries
+`default-auto-update: [true]` so fresh clients pick up the default
+unless they make a local opt-in / opt-out choice.
+
+Policies that use the `funnel` cap, `ipPool` blocks, or
+`autogroup:admin` / `autogroup:owner` targets are rejected at load —
+those features depend on machinery headscale does not yet ship.
+
+[#3251](https://github.com/juanfont/headscale/pull/3251)
+
+### Taildrive
+
+Taildrive ([file-sync between
+nodes](https://tailscale.com/docs/features/taildrive)) is now
+configurable through policy. Grant `drive:share` to the node that
+hosts files and `drive:access` to nodes that read or write them; pair
+with a `tailscale.com/cap/drive` grant to set the per-share access
+mode:
+
+```jsonc
+{
+  "nodeAttrs": [
+    { "target": ["tag:fileserver"], "attr": ["drive:share"] },
+    { "target": ["autogroup:member"], "attr": ["drive:access"] },
+  ],
+  "grants": [
+    {
+      "src": ["autogroup:member"],
+      "dst": ["tag:fileserver"],
+      "app": {
+        "tailscale.com/cap/drive": [{ "shares": ["*"], "access": "rw" }],
+      },
+    },
+  ],
+}
+```
+
+A wildcard `nodeAttrs` (`"target": ["*"]`) hands the caps to every
+node when fine-grained control is not needed.
+
+### Hostname sanitisation
+
+Hostnames are now santised using Tailscales `magicdns` sanitisation rules, matching Tailscale SaaS behavior. This means that hostnames with non-ASCII characters, special characters, or reserved DNS label characters are now transformed into valid DNS labels for MagicDNS. This improves our previously too strict sanitisation that rejected hostnames based on our guesswork and not based on the Tailscale upstream behaviour.
+
+Examples that previously regressed and now work:
+
+| Input                | Raw (Hostname)       | DNS label (GivenName) |
+| -------------------- | -------------------- | --------------------- |
+| `Joe's Mac mini`     | `Joe's Mac mini`     | `joes-mac-mini`       |
+| `Yuri's MacBook Pro` | `Yuri's MacBook Pro` | `yuris-macbook-pro`   |
+| `Test@Host`          | `Test@Host`          | `test-host`           |
+| `mail.server`        | `mail.server`        | `mail-server`         |
+| `My-PC!`             | `My-PC!`             | `my-pc`               |
+| `我的电脑`           | `我的电脑`           | `node`                |
+
+[#3202](https://github.com/juanfont/headscale/pull/3202)
+
+### HA subnet router health probing
+
+Headscale now actively probes HA subnet routers to detect nodes that are connected but not
+forwarding traffic. The control plane periodically pings HA subnet routers via the Noise
+control channel and fails over to a healthy standby if the primary stops responding. This is
+enabled by default (`node.routes.ha.probe_interval: 10s`, `probe_timeout: 5s`) and only
+active when HA routes exist (2+ nodes advertising the same prefix). Set `probe_interval` to
+`0` to disable. This complements the existing disconnect-based failover, catching "zombie
+connected" routers that maintain their control session but cannot route packets.
+[#3194](https://github.com/juanfont/headscale/pull/3194)
+
 ### 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)
+#### Hostname handling
+
+- The `GivenName` collision policy changed from an 8-char random hash suffix (`laptop-abc12xyz`) to a monotonic numeric suffix (`laptop`, `laptop-1`, `laptop-2`, …), matching Tailscale SaaS. Empty / all-non-ASCII hostnames now fall back to the literal `node` instead of `invalid-<rand>`. MagicDNS names change on upgrade for any node whose previous label was a random-suffix form; the raw `Hostname` column is unchanged. [#3202](https://github.com/juanfont/headscale/pull/3202)

+- 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 `*`

+- 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)
+
+#### Configuration
+
+- The `randomize_client_port` server-config key was removed; the
+  toggle now lives in the policy file as a top-level
+  `randomizeClientPort` field, matching the Tailscale-hosted schema. [#3251](https://github.com/juanfont/headscale/pull/3251)
+  Headscale refuses to start when the old key is set. Move it to the
+  policy file referenced by `policy.path`:
+
+  ```jsonc
+  {
+    "randomizeClientPort": true,
+  }
+  ```
+
+  If you do not have a policy file yet, create one with that minimal
+  content and point `policy.path` at it. The default carries over —
+  empty / absent policy means `randomizeClientPort: false`, matching
+  the previous behaviour for operators who never set the key. Per-node
+  opt-in via `nodeAttrs` is also supported and stacks on top of the
+  global default.
+
+#### 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
 
-- **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)

-- 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)
+#### ACL Policy
+

+- Fix filter rule reduction to use only approved subnet routes instead of all advertised routes, matching Tailscale SaaS behavior [#3175](https://github.com/juanfont/headscale/pull/3175)
+- Add ICMP and IPv6-ICMP protocols to default filter rules when no protocol is specified [#3036](https://github.com/juanfont/headscale/pull/3036)

 - 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)
+- Reject policies whose `user@` tokens match multiple DB users; rename the duplicate via `headscale users rename` to load [#3160](https://github.com/juanfont/headscale/issues/3160)
+- Evaluate the policy `tests` block on user-initiated writes across both `acls` and `grants`; reject policies whose tests fail (beta) [#1803](https://github.com/juanfont/headscale/issues/1803)
+
+#### Grants
+
+- Add support for policy grants with `ip`, `app`, and `via` fields [#2180](https://github.com/juanfont/headscale/pull/2180)

+- Fix `DestroyUser` deleting all pre-auth keys in the database instead of only the target user's keys [#3155](https://github.com/juanfont/headscale/pull/3155)
+- `headscale policy check` evaluates the `tests` block when invoked with `--bypass-grpc-and-access-database-directly`; without the flag it warns instead of running the tests against empty data [#1803](https://github.com/juanfont/headscale/issues/1803)

+  - 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`
+- Add `trusted_proxies` to gate `True-Client-IP` / `X-Real-IP` / `X-Forwarded-For` (previously honoured from any client) [#3268](https://github.com/juanfont/headscale/pull/3268)
+
+#### Debug
+
+- Add node connectivity ping page for verifying control-plane reachability [#3183](https://github.com/juanfont/headscale/pull/3183)

+- Fix `tailscaled` restart on a node with no expiry resetting `NULL` to `0001-01-01 00:00:00` in the database, affecting both tagged and untagged nodes [#3197](https://github.com/juanfont/headscale/pull/3197)
+- Backfill `nodes.expiry` rows persisted by older versions as `0001-01-01 00:00:00` to `NULL`, so nodes upgraded from <0.28 stop reporting as expired [#3284](https://github.com/juanfont/headscale/issues/3284)

+# cmd/dev -- Local Development Environment
+
+Starts a headscale server on localhost with a pre-created user and
+pre-auth key. Pair with `mts` to add real tailscale nodes.
+
+## Quick start
+
+```bash
+# Terminal 1: start headscale
+go run ./cmd/dev
+
+# Terminal 2: start mts server
+go tool mts server run
+
+# Terminal 3: add and connect nodes
+go tool mts server add node1
+go tool mts server add node2
+
+# Disable logtail (avoids startup delays, see "Known issues" below)
+for n in node1 node2; do
+  cat > ~/.config/multi-tailscale-dev/$n/env.txt << 'EOF'
+TS_NO_LOGS_NO_SUPPORT=true
+EOF
+done
+
+# Restart nodes so env.txt takes effect
+go tool mts server stop node1 && go tool mts server start node1
+go tool mts server stop node2 && go tool mts server start node2
+
+# Connect to headscale (use the auth key printed by cmd/dev)
+go tool mts node1 up --login-server=http://127.0.0.1:8080 --authkey=<KEY> --reset
+go tool mts node2 up --login-server=http://127.0.0.1:8080 --authkey=<KEY> --reset
+
+# Verify
+go tool mts node1 status
+```
+
+## Flags
+
+| Flag     | Default | Description                  |
+| -------- | ------- | ---------------------------- |
+| `--port` | 8080    | Headscale listen port        |
+| `--keep` | false   | Keep state directory on exit |
+
+The metrics/debug port is `port + 1010` (default 9090).
+
+## What it does
+
+1. Builds the headscale binary into a temp directory
+2. Writes a minimal dev config (SQLite, public DERP, debug logging)
+3. Starts `headscale serve` as a subprocess
+4. Creates a "dev" user and a reusable 24h pre-auth key via the CLI
+5. Prints a banner with server URL, auth key, and usage instructions
+6. Blocks until Ctrl+C, then kills headscale
+
+State lives in `/tmp/headscale-dev-*/`. Pass `--keep` to preserve it
+across restarts (useful for inspecting the database or reusing keys).
+
+## Useful endpoints
+
+- `http://127.0.0.1:8080/health` -- health check
+- `http://127.0.0.1:9090/debug/ping` -- interactive ping UI
+- `http://127.0.0.1:9090/debug/ping?node=1` -- quick-ping a node
+- `POST http://127.0.0.1:9090/debug/ping` with `node=<id>` -- trigger ping
+
+## Managing headscale
+
+The banner prints the full path to the built binary and config. Use it
+for any headscale CLI command:
+
+```bash
+/tmp/headscale-dev-*/headscale -c /tmp/headscale-dev-*/config.yaml nodes list
+/tmp/headscale-dev-*/headscale -c /tmp/headscale-dev-*/config.yaml users list
+```
+
+## Known issues
+
+### Logtail delays on mts nodes
+
+Freshly created `mts` instances may take 30+ seconds to start if
+`~/.local/share/tailscale/` contains stale logtail cache from previous
+tailscaled runs. The daemon blocks trying to upload old logs before
+creating its socket.
+
+Fix: write `TS_NO_LOGS_NO_SUPPORT=true` to each instance's `env.txt`
+before starting (or restart after writing). See the quick start above.
+
+### mts node cleanup
+
+`mts` stores state in `~/.config/multi-tailscale-dev/`. Old instances
+accumulate over time. Clean them with:
+
+```bash
+go tool mts server rm <name>
+```

-# hi
+# hi — Headscale Integration test runner
 
-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.
+`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.
+
+## Commands
+
+| Command            | Purpose                                              |

+| `--clean-after`     | `true`         | Clean this run's containers after completion                                |
+| `--keep-on-failure` | `false`        | Preserve containers for manual inspection on failure                        |

+| `--verbose`         | `false`        | Verbose output                                                              |
+| `--stats`           | `false`        | Collect container resource-usage stats                                      |
+| `--hs-memory-limit` | `0`            | Fail if any headscale container exceeds N MB (0 = disabled)                 |
+| `--ts-memory-limit` | `0`            | Fail if any tailscale container exceeds N MB                                |
+
+### 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:

-Headscale implements the same policy ACLs as Tailscale.com, adapted to the self-hosted environment.
-
-For instance, instead of referring to users when defining groups you must
-use users (which are the equivalent to user/logins in Tailscale.com).
-
-Please check https://tailscale.com/kb/1018/acls/ for further information.
-
-When using ACL's the User borders are no longer applied. All machines
-whichever the User have the ability to communicate with other hosts as
-long as the ACL's permits this exchange.
-
-## ACL Setup
-
-To enable and configure ACLs in Headscale, you need to specify the path to your ACL policy file in the `policy.path` key in `config.yaml`.
-
-Your ACL policy file must be formatted using [huJSON](https://github.com/tailscale/hujson).
-
-Info on how these policies are written can be found
-[here](https://tailscale.com/kb/1018/acls/).
-
-Please reload or restart Headscale after updating the ACL file. Headscale may be reloaded either via its systemd service
-(`sudo systemctl reload headscale`) or by sending a SIGHUP signal (`sudo kill -HUP $(pidof headscale)`) to the main
-process. Headscale logs the result of ACL policy processing after each reload.
-
-## Simple Examples
-
-- [**Allow All**](https://tailscale.com/kb/1192/acl-samples#allow-all-default-acl): If you define an ACL file but completely omit the `"acls"` field from its content, Headscale will default to an "allow all" policy. This means all devices connected to your tailnet will be able to communicate freely with each other.
-
-    ```json
-    {}
-    ```
-
-- [**Deny All**](https://tailscale.com/kb/1192/acl-samples#deny-all): To prevent all communication within your tailnet, you can include an empty array for the `"acls"` field in your policy file.
-
-    ```json
-    {
-      "acls": []
-    }
-    ```
-
-## Complex Example
-
-Let's build a more complex example use case for a small business (It may be the place where
-ACL's are the most useful).
-
-We have a small company with a boss, an admin, two developers and an intern.
-
-The boss should have access to all servers but not to the user's hosts. Admin
-should also have access to all hosts except that their permissions should be
-limited to maintaining the hosts (for example purposes). The developers can do
-anything they want on dev hosts but only watch on productions hosts. Intern
-can only interact with the development servers.
-
-There's an additional server that acts as a router, connecting the VPN users
-to an internal network `10.20.0.0/16`. Developers must have access to those
-internal resources.
-
-Each user have at least a device connected to the network and we have some
-servers.
-
-- database.prod
-- database.dev
-- app-server1.prod
-- app-server1.dev
-- billing.internal
-- router.internal
-
-![ACL implementation example](../assets/images/headscale-acl-network.png)
-
-When [registering the servers](../usage/getting-started.md#register-a-node) we
-will need to add the flag `--advertise-tags=tag:<tag1>,tag:<tag2>`, and the user
-that is registering the server should be allowed to do it. Since anyone can add
-tags to a server they can register, the check of the tags is done on headscale
-server and only valid tags are applied. A tag is valid if the user that is
-registering it is allowed to do it.
-
-Here are the ACL's to implement the same permissions as above:

-### WebSockets
+Please see [limitations](#limitations) for known issues and limitations.
 
-The reverse proxy MUST be configured to support WebSockets to communicate with Tailscale clients.
+## Configuration
 
-WebSockets support is also required when using the Headscale [embedded DERP server](../derp.md). In this case, you will also need to expose the UDP port used for STUN (by default, udp/3478). Please check our [config-example.yaml](https://github.com/juanfont/headscale/blob/main/config-example.yaml).

+
+Tailscale clients are using a custom protocol (Tailscale Control Protocol) to communicate with a control server such as
+Headscale. The reverse proxy **must** be configured to support WebSockets in order to communicate with Tailscale clients
+and it needs to handle two peculiarities of the Tailscale Control Protocol:
+
+- The POST method is used to upgrade the WebSocket connection.
+- The value for the `Upgrade` header is `tailscale-control-protocol`.
 
 ### TLS
 
-Headscale can be configured not to use TLS, leaving it to the reverse proxy to handle. Add the following configuration values to your headscale config file.
+Headscale can be configured not to use TLS, leaving it to the reverse proxy to handle. Add the following configuration

+```yaml title="config.yaml" hl_lines="1"
+server_url: https://<SERVER_NAME>
 tls_cert_path: ""
 tls_key_path: ""
 ```
 
-## nginx
+Headscale logs `WRN listening without TLS but ServerURL does not start with http://` during startup. This is expected
+and indicates that the reverse proxy is in charge of terminating TLS.
 
-The following example configuration can be used in your nginx setup, substituting values as necessary. `<IP:PORT>` should be the IP address and port where headscale is running. In most cases, this will be `http://localhost:8080`.
+### Trusted proxies
 
-```nginx title="nginx.conf"
-map $http_upgrade $connection_upgrade {
-    default      upgrade;
-    ''           close;
+Headscale ignores `True-Client-IP`, `X-Real-IP` and `X-Forwarded-For` headers unless the request's TCP peer matches the
+`trusted_proxies` configuration option. Set this to the CIDR(s) your reverse proxy connects from so the real client IP
+appears in access logs.
+
+```yaml title="config.yaml"
+trusted_proxies:
+  - 127.0.0.1/32
+  - ::1/128
+```
+
+The reverse proxy is responsible to replace any client-supplied `True-Client-IP`, `X-Real-IP`, `X-Forwarded-For` headers
+on inbound requests with sanitized values. Headscale picks the first valid IP address supplied by headers in this order:
+
+- `True-Client-IP`
+- `X-Real-IP`
+- `X-Forwarded-For`
+
+## Limitations
+
+- A reverse proxy adds another layer of complexity that needs to be able to handle the [Tailscale Control
+  Protocol](#websocket) properly. Be sure to test your setup without a reverse proxy before raising an issue.
+- STUN (used along with the [embedded DERP server](../derp.md)) requires udp/3478 to be served publicly.

+is [assumed](../../setup/requirements.md):
+
+- Service for Tailscale clients is served via HTTPS on port 443.
+- The reverse proxy redirects HTTP to HTTPS and is terminating TLS.

+# Policy
+
+Headscale implements a large portion of Tailscale's [policy
+features](https://tailscale.com/docs/features/tailnet-policy-file), most notably access control based on
+[ACLs](https://tailscale.com/docs/features/access-control/acls) and
+[Grants](https://tailscale.com/docs/features/access-control/grants) or [Tailscale
+SSH](https://tailscale.com/docs/features/tailscale-ssh). See [limitations](#limitations) to learn about missing features
+and notable implementation differences between Headscale and Tailscale.
+
+Headscale uses the same [huJSON](https://github.com/tailscale/hujson) based file format as Tailscale. By default, no
+policy is loaded which means that Headscale allows all traffic between nodes. To start using a policy file[^1], specify
+its path in the `policy.path` key in the [configuration file](configuration.md).
+
+Headscale needs to be reloaded to pick up changes to the policy file. Either reload Headscale via its systemd service
+(`sudo systemctl reload headscale`) or by sending a SIGHUP signal (`sudo kill -HUP $(pidof headscale)`) to the main
+process. Headscale logs the result of policy processing after each reload.
+
+Please have a look at Tailscale's policy related documentation to learn more:
+
+- [Tailscale policy file](https://tailscale.com/docs/features/tailnet-policy-file): A description of supported sections
+  within the policy file along with links to syntax references for each section.
+- [ACLs](https://tailscale.com/docs/features/access-control/acls): How to configure access control using ACLs.
+- [Grants](https://tailscale.com/docs/features/access-control/grants): Introduction to Grants with links to [syntax
+  reference](https://tailscale.com/docs/reference/syntax/grants),
+  [examples](https://tailscale.com/docs/reference/examples/grants) and a [migration guide from ACLs to
+  Grants](https://tailscale.com/docs/reference/migrate-acls-grants).
+
+## Getting started
+
+Headscale supports both [ACLs](https://tailscale.com/docs/features/access-control/acls) and
+[Grants](https://tailscale.com/docs/features/access-control/grants) to write an access control policy. We recommend the
+use of Grants since ACLs are considered legacy and will not receive new features by Tailscale.
+
+### Allow All
+
+If you define a policy file but completely omit the `"acls"` or `"grants"` section, Headscale will default to an [allow
+all](https://tailscale.com/docs/reference/examples/acls#allow-all-default-acl) policy. This means all devices connected
+to your tailnet will be able to communicate freely with each other.
+
+```json title="policy.json"
+{}
+```
+
+### Deny All
+
+To [prevent all communication within your tailnet](https://tailscale.com/docs/reference/examples/acls#deny-all), you can
+include an empty array for the `"grants"` section in your policy file.
+
+```json title="policy.json"
+{
+  "grants": []
+}
+```
+
+### More examples
+
+- See our documentation on [subnet routers](routes.md#subnet-router) and [exit nodes](routes.md#exit-node) to learn how
+  to restrict their use or how to automatically approve them.
+- The Tailscale documentation provides a large collection of configuration examples:
+    - [ACL examples](https://tailscale.com/docs/reference/examples/acls)
+    - [Grants examples](https://tailscale.com/docs/reference/examples/grants)
+    - [SSH configuration](https://tailscale.com/docs/features/tailscale-ssh#configure-tailscale-ssh)
+    - [Define a tag](https://tailscale.com/docs/features/tags#define-a-tag)
+
+______________________________________________________________________
+
+## Limitations
+
+- [Device postures](https://tailscale.com/docs/features/device-posture) and the related sections such as `postures` or
+  `srcPosture` aren't supported.
+- [IP sets](https://tailscale.com/docs/features/tailnet-policy-file/ip-sets) aren't supported.
+- A subset of [Autogroups](#autogroups) are available.
+
+## Autogroups
+
+Headscale supports several [Autogroups](https://tailscale.com/docs/reference/targets-and-selectors#autogroups) that
+automatically include users, destinations, or devices with specific properties. Autogroups provide a convenient way to
+write policy rules without manually listing individual users or devices.
+
+### [`autogroup:internet`](https://tailscale.com/docs/reference/targets-and-selectors#autogroupinternet)
+
+Allows access to the internet through [exit nodes](routes.md#exit-node). Can only be used in policy destinations.
+
+```json title="policy.json"
+{
+  "grants": [
+    {
+      "src": ["alice@"],
+      "dst": ["autogroup:internet"],
+      "ip": ["*"]
+    }
+  ]
+}
+```
+
+### [`autogroup:member`](https://tailscale.com/docs/reference/targets-and-selectors#autogrouprole)
+
+Includes all [personal (untagged) devices](registration.md/#identity-model).
+
+```json title="policy.json"
+{
+  "grants": [
+    {
+      "src": ["autogroup:member"],
+      "dst": ["tag:prod-app-servers"],
+      "ip": ["80,443"]
+    }
+  ]
+}
+```
+
+### [`autogroup:tagged`](https://tailscale.com/docs/reference/targets-and-selectors#autogrouptagged)
+
+Includes all devices that [have at least one tag](registration.md/#identity-model).
+
+```json title="policy.json"
+{
+  "grants": [
+    {
+      "src": ["autogroup:tagged"],
+      "dst": ["tag:monitoring"],
+      "ip": ["9090"]
+    }
+  ]
+}
+```
+
+### [`autogroup:self`](https://tailscale.com/docs/reference/targets-and-selectors#autogroupself)
+
+Includes devices where the same user is authenticated on both the source and destination. Does not include tagged
+devices. Can only be used in policy destinations.
+
+```json title="policy.json"
+{
+  "grants": [
+    {
+      "src": ["autogroup:member"],
+      "dst": ["autogroup:self"],
+      "ip": ["*"]
+    }
+  ]
+}
+```
+
+!!! warning "The current implementation of `autogroup:self` is inefficient"
+
+    Using `autogroup:self` may cause performance degradation on the Headscale coordinator server in large deployments,
+    as filter rules must be compiled per-node rather than globally and the current implementation is not very efficient.
+
+    If you experience performance issues, consider using more specific policy rules or limiting the use of
+    `autogroup:self`.
+
+    ```json title="policy.json"
+    {
+      "grants": [
+        // The following rules allow internal users to communicate with their
+        // own nodes in case autogroup:self is causing performance issues.
+        {
+          "src": ["boss@"],
+          "dst": ["boss@"],
+          "ip": ["*"]
+        },
+        {
+          "src": ["dev1@"],
+          "dst": ["dev1@"],
+          "ip": ["*"]
+        },
+        {

+          "ip": ["*"]
+        }
+      ]
+    }
+    ```
+
+### [`autogroup:nonroot`](https://tailscale.com/docs/reference/targets-and-selectors#other-built-in-targets)
+
+Used in Tailscale SSH rules to allow access to any user except root. Can only be used in the `users` field of SSH rules.
+
+```json title="policy.json"
+{
+  "ssh": [
+    {
+      "action": "accept",
+      "src": ["autogroup:member"],
+      "dst": ["autogroup:self"],
+      "users": ["autogroup:nonroot"]
+    }
+  ]
+}
+```
+
+### [`autogroup:danger-all`](https://tailscale.com/docs/reference/targets-and-selectors#autogroupdanger-all)
+
+This autogroup resolves to all IP addresses (`0.0.0.0/0` and `::/0`) which also includes all IP addresses outside the
+standard Tailscale IP ranges. This autogroup can only be used as source.
+
+## Node Attributes
+
+[Node attributes](https://tailscale.com/docs/reference/syntax/policy-file#node-attributes) allow for device-specific
+configuration and attributes. At least the following node attributes are currently supported by Headscale[^2]:
+
+- `drive:access`, `drive:share`: [Taildrive support](https://tailscale.com/docs/features/taildrive).
+- `nextdns:<profile>`, `nextdns:no-device-info`: [NextDNS integration](https://tailscale.com/docs/integrations/nextdns).
+  Be sure to set NextDNS as global resolver in the [configuration](configuration.md).
+- `magicdns-aaaa`: Respond to AAAA queries on the local [MagicDNS](https://tailscale.com/docs/features/magicdns)
+  resolver at 100.100.100.100.
+- `disable-ipv4`: Selectively disable IPv4 for specfic nodes. This is may be useful to workaround [CGNat
+  conflicts](https://tailscale.com/docs/reference/troubleshooting/network-configuration/cgnat-conflicts).
+- `randomize-client-port`: Allocate a [random port for WireGuard
+  traffic](https://tailscale.com/docs/reference/syntax/policy-file#randomizeclientport) instead of the static default
+  port 41641.
+- `disable-captive-portal-detection`: [Disable automatic captive portal
+  detection](https://tailscale.com/docs/integrations/captive-portals#disable-captive-portal-detection).
+
+```json title="policy.json"
+{
+  "nodeAttrs": [
+    {
+      // Enable MagicDNS AAAA records for all nodes
+      "target": ["*"]
+      "attr": ["magicdns-aaaa"]
+    }
+  ]
+}
+```
+
+## Network-wide policy options
+
+The following options are applied for the entire tailnet. Consider [node attributes](#node-attributes) for a more
+fine-grained configuration instead.
+
+- `randomizeClientPort`: Allocate a [random port for WireGuard
+  traffic](https://tailscale.com/docs/reference/syntax/policy-file#randomizeclientport) instead of the static default
+  port 41641.
+
+```json title="policy.json"
+{
+  // Use a random WireGuard port for the entire tailnet
+  "randomizeClientPort": true
+}
+```
+
+[^1]: Headscale also allows to store the policy in the database. This is typically only required in case a [web
+    interface](integration/web-ui.md) is used.
+
+[^2]: Other key-only node attributes can be used as well. Find them in the client source code with `grep -E '^\s+NodeAttr\w+' tailcfg/tailcfg.go` or by using [GitHub code search (requires

 ## High availability
 
-Headscale has limited support for high availability routing. Multiple subnet routers with overlapping routes or multiple
-exit nodes can be used to provide high availability for users. If one router node goes offline, another one can serve

-!!! bug
-
-    In certain situations it might take up to 16 minutes for Headscale to detect a node as offline. A failover node
-    might not be selected fast enough, if such a node is used as subnet router or exit node causing service
-    interruptions for clients. See [issue 2129](https://github.com/juanfont/headscale/issues/2129) for more information.
+This feature is enabled by default when at least two nodes advertise the same prefix. See the configuration options
+`node.routes.ha` in the [configuration file](configuration.md) for details.
 
 ## Troubleshooting
 
 ### Enable IP forwarding
 
 A subnet router or exit node is routing traffic on behalf of other nodes and thus requires IP forwarding. Check the
