+# Caddy Project Guidelines
+
+## Mission
+
+**Every site on HTTPS.** Caddy is a security-first, modular, extensible server platform.
+
+## Code Style
+
+### Go Idioms
+
+Follow [Go Code Review Comments](https://go.dev/wiki/CodeReviewComments):
+
+- **Error flow**: Early return, indent error handling—not else blocks
+  ```go
+  if err != nil {
+      return err
+  }
+  // normal code
+  ```
+- **Naming**: initialisms (`URL`, `HTTP`, `ID`—not `Url`, `Http`, `Id`)
+- **Receiver names**: 1–2 letters reflecting type (`c` for `Client`, `h` for `Handler`)
+- **Error strings**: Lowercase, no trailing punctuation (`"something failed"` not `"Something failed."`)
+- **Doc comments**: Full sentences starting with the name being documented
+  ```go
+  // Handler serves HTTP requests for the file server.
+  type Handler struct { ... }
+  ```
+- **Empty slices**: `var t []string` (nil slice), not `t := []string{}` (non-nil zero-length)
+- **Don't panic**: Use error returns for normal error handling
+
+### Caddy Patterns
+
+**Module registration**:
+```go
+func init() {
+    caddy.RegisterModule(MyModule{})
+}
+
+func (MyModule) CaddyModule() caddy.ModuleInfo {
+    return caddy.ModuleInfo{
+        ID:  "namespace.category.name",
+        New: func() caddy.Module { return new(MyModule) },
+    }
+}
+```
+
+**Module lifecycle**: `New()` → JSON unmarshal → `Provision()` → `Validate()` → use → `Cleanup()`
+
+**Interface guards** — compile-time verification that modules implement required interfaces:
+```go
+var (
+    _ caddy.Provisioner     = (*MyModule)(nil)
+    _ caddy.Validator       = (*MyModule)(nil)
+    _ caddyfile.Unmarshaler = (*MyModule)(nil)
+)
+```
+
+**Structured logging** — use the module-scoped logger from context:
+```go
+func (m *MyModule) Provision(ctx caddy.Context) error {
+    m.logger = ctx.Logger()
+    m.logger.Debug("provisioning", zap.String("field", m.Field))
+    return nil
+}
+```
+
+**Caddyfile support** — implement `UnmarshalCaddyfile(*caddyfile.Dispenser)` using the `Dispenser` API:
+```go
+// UnmarshalCaddyfile sets up the module from Caddyfile tokens. Syntax:
+//
+//     directive [arg1] [arg2] {
+//         subdir value
+//     }
+func (m *MyModule) UnmarshalCaddyfile(d *caddyfile.Dispenser) error {
+    d.Next() // consume directive name
+    for d.NextArg() {
+        // handle inline arguments
+    }
+    for nesting := d.Nesting(); d.NextBlock(nesting); {
+        switch d.Val() {
+        case "subdir":
+            if !d.NextArg() {
+                return d.ArgErr()
+            }
+            m.Field = d.Val()
+        default:
+            return d.Errf("unrecognized subdirective: %s", d.Val())
+        }
+    }
+    return nil
+}
+```
+
+**Admin API**: Implement `caddy.AdminRouter` for custom endpoints.
+
+**Context**: Use `caddy.Context` for accessing other apps/modules and logging—don't store contexts in structs.
+
+## Architecture
+
+Caddy is built around a **module system** where everything is a module registered via `caddy.RegisterModule()`:
+
+- **Apps** (`caddy.App`): Top-level modules like `http`, `tls`, `pki` that Caddy loads and runs
+- **Modules** (`caddy.Module`): Extensible components with namespaced IDs (e.g., `http.handlers.file_server`)
+- **Configuration**: Native JSON with adapters (Caddyfile → JSON via `caddyconfig/httpcaddyfile`)
+
+| Directory | Purpose |
+|-----------|---------|
+| `modules/` | All standard modules (HTTP, TLS, PKI, etc.) |
+| `modules/standard/imports.go` | Standard module registry |
+| `caddyconfig/httpcaddyfile/` | Caddyfile → JSON adapter for HTTP |
+| `caddytest/` | Test utilities and integration tests |
+| `cmd/caddy/` | CLI entry point with module imports |
+
+### Critical Packages
+
+`caddyhttp` and `caddytls` require **extra scrutiny** in code review—these are security-critical.
+
+## Quality Gates
+
+
+**All required before PR is merge-ready:**
+
+| Gate | Command | Notes |
+|------|---------|-------|
+| Tests pass | `go test -race -short ./...` | Race detection enabled |
+| Lint clean | `golangci-lint run --timeout 10m` | No warnings in changed files |
+| Builds | `go build ./...` | Must compile |
+| Benchmarks | `go test -bench=. -benchmem` | Required for optimizations |
+
+CI runs tests on **Linux, macOS, and Windows**—ensure cross-platform compatibility.
+
+### Build & Test
+
+```bash
+# Build
+cd cmd/caddy && go build
+
+# Tests with race detection (matches CI)
+go test -race -short ./...
+
+# Integration tests
+go test ./caddytest/integration/...
+
+# Lint (matches CI)
+golangci-lint run --timeout 10m
+```
+
+## Testing Conventions
+
+**Table-driven tests** (preferred pattern):
+```go
+func TestFeature(t *testing.T) {
+    for i, tc := range []struct {
+        input    string
+        expected string
+        wantErr  bool
+    }{
+        {input: "valid", expected: "result", wantErr: false},
+        {input: "invalid", expected: "", wantErr: true},
+    } {
+        actual, err := Function(tc.input)
+        if tc.wantErr && err == nil {
+            t.Errorf("Test %d: expected error but got none", i)
+        }
+        if !tc.wantErr && err != nil {
+            t.Errorf("Test %d: unexpected error: %v", i, err)
+        }
+        if actual != tc.expected {
+            t.Errorf("Test %d: expected %q, got %q", i, tc.expected, actual)
+        }
+    }
+}
+```
+
+**Integration tests** use `caddytest.Tester`:
+```go
+func TestHTTPFeature(t *testing.T) {
+    tester := caddytest.NewTester(t)
+    tester.InitServer(`
+    {
+        admin localhost:2999
+        http_port 9080
+    }
+    localhost:9080 {
+        respond "hello"
+    }`, "caddyfile")
+    
+    tester.AssertGetResponse("http://localhost:9080/", 200, "hello")
+}
+```
+
+Use non-standard ports (9080, 9443, 2999) to avoid conflicts with running servers.
+
+## AI Contribution Policy
+
+Per [CONTRIBUTING.md](.github/CONTRIBUTING.md), AI-assisted code **MUST** be:
+
+1. **Disclosed** — Tell reviewers when code was AI-generated or AI-assisted, mentioning which agent/model is used
+2. **Fully comprehended** — You must be able to explain every line
+3. **Tested** — Automated tests when feasible, thorough manual tests otherwise
+4. **Licensed** — Verify AI output doesn't include plagiarized or incompatibly-licensed code
+5. **Contributor License Agreement (CLA)** — The CLA must be signed by the human user
+
+**Do NOT submit code you cannot fully explain.** Contributors are responsible for their submissions.
+
+## Dependencies
+
+- **Avoid new dependencies** — Justify any additions; tiny deps can be inlined
+- **No exported dependency types** — Caddy must not export types defined by external packages
+- Use Go modules; check with `go mod tidy`

+// Integration tests for Caddy's PROXY protocol support, covering two distinct
+// roles that Caddy can play:
+//
+//  1. As a PROXY protocol *sender* (reverse proxy outbound transport):
+//     Caddy receives an inbound request from a test client and the
+//     reverse_proxy handler forwards it to an upstream with a PROXY protocol
+//     header (v1 or v2) prepended to the connection.  A lightweight backend
+//     built with go-proxyproto validates that the header was received and
+//     carries the correct client address.
+//
+//     Transport versions tested:
+//   - "1.1"  -> plain HTTP/1.1 to the upstream
+//   - "h2c"  -> HTTP/2 cleartext (h2c) to the upstream (regression for #7529)
+//   - "2"    -> HTTP/2 over TLS (h2) to the upstream
+//
+//     For each transport version both PROXY protocol v1 and v2 are exercised.
+//
+//     HTTP/3 (h3) is not included because it uses QUIC/UDP and therefore
+//     bypasses the TCP-level dialContext that injects PROXY protocol headers;
+//     there is no meaningful h3 + proxy protocol sender combination to test.
+//
+//  2. As a PROXY protocol *receiver* (server-side listener wrapper):
+//     A raw TCP client dials Caddy directly, injects a PROXY v2 header
+//     spoofing a source address, and sends a normal HTTP/1.1 request.  The
+//     Caddy server is configured with the proxy_protocol listener wrapper and
+//     is expected to surface the spoofed address via the
+//     {http.request.remote.host} placeholder.
