 # PlasmaCloud/PhotonCloud と Nix-NOS の統合分析
 ## Architecture Decision (2025-12-13)
 **決定:** Nix-NOSを汎用ネットワークモジュールとして別リポジトリに分離する。
 ### Three-Layer Architecture
 ```
 Layer 3: PlasmaCloud Cluster (T061)
  - plasmacloud-cluster.nix
  - cluster-config.json生成
  - Deployer (Rust)
  depends on ↓
 Layer 2: PlasmaCloud Network (T061)
  - plasmacloud-network.nix
  - FiberLB BGP連携
  - PrismNET統合
  depends on ↓
 Layer 1: Nix-NOS Generic (T062) ← 別リポジトリ
  - BGP (BIRD2/GoBGP)
  - VLAN
  - Network interfaces
  - PlasmaCloudを知らない汎用モジュール
 ```
 ### Repository Structure
 - **github.com/centra/nix-nos**: Layer 1 (汎用、VyOS/OpenWrt代替)
 - **github.com/centra/plasmacloud**: Layers 2+3 (既存リポジトリ)
 ---

 ---
 ## 2. Nix-NOS との統合ポイント
 ### 2.1 Baremetal Provisioning → Deployer強化
 **既存の実装:**
 ```
 first-boot-automation.nix
 ├── cluster-config.json による設定注入
 ├── bootstrap vs join の自動判定
 ├── マーカーファイルによる冪等性
 └── systemd サービス連携
 ```
 **Nix-NOSで追加すべき機能:**
 | 既存 | Nix-NOS追加 |
 |------|-------------|
 | cluster-config.json (手動作成) | topology.nix から自動生成 |
 | 単一クラスタ構成 | 複数クラスタ/サイト対応 |
 | nixos-anywhere 依存 | Deployer (Phone Home + Push) |
 | 固定IP設定 | IPAM連携による動的割当 |
 **統合設計:**
 ```nix
 # topology.nix（Nix-NOS）
 {
  nix-nos.clusters.plasmacloud = {
    nodes = {
      "node01" = { 
        role = "control-plane";
        ip = "10.0.1.10";
        services = [ "chainfire" "flaredb" "iam" ];
      };
      "node02" = { role = "control-plane"; ip = "10.0.1.11"; };
      "node03" = { role = "worker"; ip = "10.0.1.12"; };
    };
    # Nix-NOSが自動生成 → first-boot-automationが読む
    # cluster-config.json の内容をNix評価時に決定
  };
 }
 ```
 ### 2.2 Network Management → PrismNET + FiberLB + Nix-NOS BGP
 **既存の実装:**
 ```
 PrismNET (prismnet/)
 ├── VPC/Subnet/Port管理
 ├── Security Groups
 ├── IPAM
 └── OVN連携
 FiberLB (fiberlb/)
 ├── L4/L7ロードバランシング
 ├── ヘルスチェック
 ├── VIP管理
 └── BGP統合（設計済み、GoBGPサイドカー）
 ```
 **Nix-NOSで追加すべき機能:**
 ```
 Nix-NOS Network Layer
 ├── BGP設定生成（BIRD2）
 │   ├── iBGP/eBGP自動計算
 │   ├── Route Reflector対応
 │   └── ポリシー抽象化
 ├── topology.nix → systemd-networkd
 ├── OpenWrt/Cisco設定生成（将来）
 └── FiberLB BGP連携
 ```
 **統合設計:**
 ```nix
 # Nix-NOSのBGPモジュール → FiberLBのGoBGP設定に統合
 {
  nix-nos.network.bgp = {
    autonomousSystems = {
      "65000" = {
        members = [ "node01" "node02" "node03" ];
        ibgp.strategy = "route-reflector";
        ibgp.reflectors = [ "node01" ];
      };
    };
    # FiberLBのVIPをBGPで広報
    vipAdvertisements = {
      "fiberlb" = {
        vips = [ "10.0.100.1" "10.0.100.2" ];
        nextHop = "self";
        communities = [ "65000:100" ];
      };
    };
  };
  # FiberLBモジュールとの連携
  services.fiberlb.bgp = {
    enable = true;
    # Nix-NOSが生成するGoBGP設定を参照
    configFile = config.nix-nos.network.bgp.gobgpConfig;
  };
 }
 ```
 ### 2.3 K8sパチモン → k8shost + Pure NixOS Alternative
 **既存の実装:**
 ```
 k8shost (k8shost/)
 ├── Pod管理（gRPC API）
 ├── Service管理（ClusterIP/NodePort）
 ├── Node管理
 ├── CNI連携
 ├── CSI連携
 └── FiberLB/FlashDNS連携
 ```
 **Nix-NOSの役割:**
 k8shostはすでにKubernetesのパチモンとして機能している。Nix-NOSは：
 1. **k8shostを使う場合**: k8shostクラスタ自体のデプロイをNix-NOSで管理
 2. **Pure NixOS（K8sなし）**: より軽量な選択肢として、Systemd + Nix-NOSでサービス管理
 ```

 │                  Orchestration Options                       │
 ├─────────────────────────────────────────────────────────────┤
 │  Option A: k8shost (K8s-like)                               │
 │  ┌─────────────────────────────────────────────────────┐   │
 │  │  Nix-NOS manages: cluster topology, network, certs  │   │
 │  │  k8shost manages: pods, services, scaling           │   │
 │  └─────────────────────────────────────────────────────┘   │
 │                                                             │
 │  Option B: Pure NixOS (K8s-free)                           │
 │  ┌─────────────────────────────────────────────────────┐   │
 │  │  Nix-NOS manages: everything                        │   │
 │  │  systemd + containers, static service discovery     │   │
 │  │  Use case: クラウド基盤自体の管理                    │   │
 │  └─────────────────────────────────────────────────────┘   │
 └─────────────────────────────────────────────────────────────┘
 ```
 **重要な洞察:**
 > 「クラウドの基盤そのものを作るのにKubernetesは使いたくない」
 これは正しいアプローチ。PlasmaCloudのコアサービス（ChainFire, FlareDB, IAM等）は：
 - K8sの上で動くのではなく、K8sを提供する側
 - Pure NixOS + Systemdで管理されるべき
 - Nix-NOSはこのレイヤーを担当
 ---
 ## 3. 具体的な統合計画
 ### Phase 1: Baremetal Provisioning統合
 **目標:** first-boot-automationをNix-NOSのtopology.nixと連携
 ```nix
 # nix/modules/first-boot-automation.nix への追加
 { config, lib, ... }:
 let
  # Nix-NOSのトポロジーから設定を生成
  clusterConfig = 
    if config.nix-nos.cluster != null then
      config.nix-nos.cluster.generateClusterConfig {
        hostname = config.networking.hostName;
      }
    else
      # 従来のcluster-config.json読み込み
      builtins.fromJSON (builtins.readFile /etc/nixos/secrets/cluster-config.json);
 in {
  # 既存のfirst-boot-automationロジックはそのまま
  # ただし設定ソースをNix-NOSに切り替え可能に
 }
 ```
 ### Phase 2: BGP/Network統合
 **目標:** FiberLBのBGP連携（T055.S3）をNix-NOSで宣言的に管理
 ```nix
 # nix/modules/fiberlb-bgp-nixnos.nix
 { config, lib, pkgs, ... }:
 let
  fiberlbCfg = config.services.fiberlb;
  nixnosBgp = config.nix-nos.network.bgp;
 in {
  config = lib.mkIf (fiberlbCfg.enable && nixnosBgp.enable) {
    # GoBGP設定をNix-NOSから生成
    services.gobgpd = {
      enable = true;
      configFile = pkgs.writeText "gobgp.yaml" (
        nixnosBgp.generateGobgpConfig {
          localAs = nixnosBgp.getLocalAs config.networking.hostName;
          routerId = nixnosBgp.getRouterId config.networking.hostName;
          neighbors = nixnosBgp.getPeers config.networking.hostName;
        }
      );
    };
    # FiberLBにGoBGPアドレスを注入
    services.fiberlb.bgp = {
      gobgpAddress = "127.0.0.1:50051";
    };
  };
 }
 ```
 ### Phase 3: Deployer実装
 **目標:** Phone Home + Push型デプロイメントコントローラー
 ```
 plasmacloud/
 ├── deployer/                      # 新規追加
 │   ├── src/
 │   │   ├── api.rs                # Phone Home API
 │   │   ├── orchestrator.rs       # デプロイワークフロー
 │   │   ├── state.rs              # ノード状態管理（ChainFire連携）
 │   │   └── iso_generator.rs      # ISO自動生成
 │   └── Cargo.toml
 └── nix/
    └── modules/
        └── deployer.nix          # NixOSモジュール
 ```
 **ChainFireとの連携:**
 DeployerはChainFireを状態ストアとして使用：
 ```rust
 // deployer/src/state.rs
 struct NodeState {
    hostname: String,
    status: NodeStatus,  // Pending, Provisioning, Active, Failed
    bootstrap_key_hash: Option<String>,
    ssh_pubkey: Option<String>,
    last_seen: DateTime<Utc>,
 }
 impl DeployerState {
    async fn register_node(&self, node: &NodeState) -> Result<()> {
        // ChainFireに保存
        self.chainfire_client
            .put(format!("deployer/nodes/{}", node.hostname), node.to_json())
            .await
    }
 }
 ```

 ## 6. 結論
 PlasmaCloud/PhotonCloudプロジェクトは、Nix-NOSの構想を実装するための**理想的な基盤**：
 1. **すでにNixOSモジュール化されている** → Nix-NOSモジュールとの統合が容易
 2. **first-boot-automationが存在** → Deployerの基礎として活用可能
 3. **FiberLBにBGP設計がある** → Nix-NOSのBGPモジュールと自然に統合
 4. **ChainFireが状態ストア** → Deployer状態管理に利用可能
 5. **k8shostが存在するがK8sではない** → 「K8sパチモン」の哲学と一致
 **次のアクション:**
 1. Nix-NOSモジュールをPlasmaCloudリポジトリに追加
 2. topology.nix → cluster-config.json生成の実装
 3. BGPモジュール（BIRD2）の実装とFiberLB連携

 ## Decision & Pivot Log (recent 5)
 - 2025-12-12 12:49 | **T039 SUSPENDED — User Directive: Software Refinement** | User explicitly directed: suspend VM deployment, focus on software refinement. Root cause discovered: disko module not imported in NixOS config (not stdio issue). T051/T052/T053-T057 prioritized.
 - 2025-12-12 06:25 | **T059 CREATED — Critical Audit Fix (P0)** | Full code audit confirmed user suspicion of quality issues. 3 critical failures: creditservice doesn't compile (txn API), chainfire tests fail (DELETE), iam tests fail (visibility). MVP-Alpha BLOCKED until fixed.
 - 2025-12-12 04:09 | **T058 CREATED — S3 Auth Hardening** | Foreman highlighted T047 S3 SigV4 auth issue. Creating T058 (P0) to address this critical security gap for production.
 - 2025-12-12 04:00 | **T039 ACTIVATED — Production Deployment** | T032 complete, removing the hardware blocker for T039. Shifting focus to bare-metal deployment and remaining production readiness tasks.
 - 2025-12-12 03:45 | **T056/T057 CREATED — Audit Follow-up** | Created T056 (FlashDNS Pagination) and T057 (k8shost Resource Management) to address remaining gaps identified in T049 Component Audit.
 - 2025-12-12 03:25 | **T047 ACCEPTED — S3 Auth Deferral** | S3 API is functional with AWS CLI. Auth SigV4 canonicalization mismatch bypassed (`S3_AUTH_ENABLED=false`) to unblock MVP usage. Fix deferred to T039/Security phase.

 # T039.S6 Integration Test Plan
 **Owner**: peerA
 **Prerequisites**: S3-S5 complete (NixOS provisioned, services deployed, clusters formed)
 ## Test Categories
 ### 1. Service Health Checks
 Verify all 11 services respond on all 3 nodes.
 ```bash
 # Node IPs (from T036 config)
 NODES=(192.168.100.11 192.168.100.12 192.168.100.13)
 # Service ports (from nix/modules/*.nix - verified 2025-12-12)
 declare -A SERVICES=(
  ["chainfire"]=2379
  ["flaredb"]=2479
  ["iam"]=3000
  ["plasmavmc"]=4000

  ["fiberlb"]=7000
  ["prismnet"]=5000
  ["k8shost"]=6443
  ["nightlight"]=9101
  ["creditservice"]=3010
 )
 # Health check each service on each node
 for node in "${NODES[@]}"; do
  for svc in "${!SERVICES[@]}"; do
    grpcurl -plaintext $node:${SERVICES[$svc]} list || echo "FAIL: $svc on $node"
  done
 done
 ```
 **Expected**: All services respond with gRPC reflection
 ### 2. Cluster Formation Validation
 #### 2.1 ChainFire Cluster
 ```bash
 # Check cluster status on each node
 for node in "${NODES[@]}"; do
  grpcurl -plaintext $node:2379 chainfire.ClusterService/GetStatus
 done
 ```
 **Expected**:
 - 3 nodes in cluster
 - Leader elected
 - All nodes healthy
 #### 2.2 FlareDB Cluster
 ```bash
 # Check FlareDB cluster health
 for node in "${NODES[@]}"; do
  grpcurl -plaintext $node:2479 flaredb.AdminService/GetClusterStatus
 done
 ```
 **Expected**:
 - 3 nodes joined
 - Quorum formed (2/3 minimum)
 ### 3. Cross-Component Integration (T029 Scenarios)
 #### 3.1 IAM Authentication Flow
 ```bash
 # Create test organization
 grpcurl -plaintext $NODES[0]:3000 iam.OrgService/CreateOrg \
  -d '{"name":"test-org","display_name":"Test Organization"}'
 # Create test user
 grpcurl -plaintext $NODES[0]:3000 iam.UserService/CreateUser \
  -d '{"org_id":"test-org","username":"testuser","password":"testpass"}'
 # Authenticate and get token
 TOKEN=$(grpcurl -plaintext $NODES[0]:3000 iam.AuthService/Authenticate \
  -d '{"username":"testuser","password":"testpass"}' | jq -r '.token')
 # Validate token
 grpcurl -plaintext $NODES[0]:3000 iam.AuthService/ValidateToken \
  -d "{\"token\":\"$TOKEN\"}"
 ```
 **Expected**: Token issued and validated successfully
 #### 3.2 FlareDB Storage
 ```bash
 # Write data
 grpcurl -plaintext $NODES[0]:2479 flaredb.KVService/Put \
  -d '{"key":"test-key","value":"dGVzdC12YWx1ZQ=="}'
 # Read from different node (replication test)
 grpcurl -plaintext $NODES[1]:2479 flaredb.KVService/Get \
  -d '{"key":"test-key"}'
 ```
 **Expected**: Data replicated across nodes
 #### 3.3 LightningSTOR S3 Operations
 ```bash
 # Create bucket via S3 API
 curl -X PUT http://$NODES[0]:9100/test-bucket
 # Upload object
 curl -X PUT http://$NODES[0]:9100/test-bucket/test-object \
  -d "test content"
 # Download object from different node
 curl http://$NODES[1]:9100/test-bucket/test-object
 ```
 **Expected**: Object storage working, multi-node accessible
 #### 3.4 FlashDNS Resolution
 ```bash
 # Add DNS record
 grpcurl -plaintext $NODES[0]:6000 flashdns.RecordService/CreateRecord \
  -d '{"zone":"test.cloud","name":"test","type":"A","value":"192.168.100.100"}'
 # Query DNS from different node
 dig @$NODES[1] test.test.cloud A +short
 ```
 **Expected**: DNS record created and resolvable
 ### 4. Nightlight Metrics Collection
 ```bash
 # Check Prometheus endpoint on each node
 for node in "${NODES[@]}"; do
  curl -s http://$node:9090/api/v1/targets | jq '.data.activeTargets | length'
 done
 # Query metrics
 curl -s "http://$NODES[0]:9090/api/v1/query?query=up" | jq '.data.result'
 ```
 **Expected**: All targets up, metrics being collected
 ### 5. FiberLB Load Balancing (T051 Validation)
 ```bash
 # Create load balancer for test service
 grpcurl -plaintext $NODES[0]:7000 fiberlb.LBService/CreateLoadBalancer \
  -d '{"name":"test-lb","org_id":"test-org"}'
 # Create pool with round-robin
 grpcurl -plaintext $NODES[0]:7000 fiberlb.PoolService/CreatePool \
  -d '{"lb_id":"...","algorithm":"ROUND_ROBIN","protocol":"TCP"}'
 # Add backends
 for i in 1 2 3; do
  grpcurl -plaintext $NODES[0]:7000 fiberlb.BackendService/CreateBackend \
    -d "{\"pool_id\":\"...\",\"address\":\"192.168.100.1$i\",\"port\":8080}"
 done
 # Verify distribution (requires test backend servers)
 for i in {1..10}; do
  curl -s http://<VIP>:80 | head -1
 done | sort | uniq -c
 ```
 **Expected**: Requests distributed across backends
 ### 6. PrismNET Overlay Networking
 ```bash
 # Create VPC
 grpcurl -plaintext $NODES[0]:5000 prismnet.VPCService/CreateVPC \
  -d '{"name":"test-vpc","cidr":"10.0.0.0/16"}'
 # Create subnet
 grpcurl -plaintext $NODES[0]:5000 prismnet.SubnetService/CreateSubnet \
  -d '{"vpc_id":"...","name":"test-subnet","cidr":"10.0.1.0/24"}'
 # Create port
 grpcurl -plaintext $NODES[0]:5000 prismnet.PortService/CreatePort \
  -d '{"subnet_id":"...","name":"test-port"}'
 ```
 **Expected**: VPC/subnet/port created successfully
 ### 7. CreditService Quota (If Implemented)
 ```bash
 # Check wallet balance
 grpcurl -plaintext $NODES[0]:3010 creditservice.WalletService/GetBalance \
  -d '{"org_id":"test-org","project_id":"test-project"}'
 ```
 **Expected**: Quota system responding
 ### 8. Node Failure Resilience
 ```bash
 # Shutdown node03
 ssh root@$NODES[2] "systemctl stop chainfire flaredb"
 # Verify cluster still operational (quorum: 2/3)
 grpcurl -plaintext $NODES[0]:2379 chainfire.ClusterService/GetStatus
 # Write data
 grpcurl -plaintext $NODES[0]:2479 flaredb.KVService/Put \
  -d '{"key":"failover-test","value":"..."}'
 # Read data
 grpcurl -plaintext $NODES[1]:2479 flaredb.KVService/Get \
  -d '{"key":"failover-test"}'
 # Restart node03
 ssh root@$NODES[2] "systemctl start chainfire flaredb"
 # Verify rejoin
 sleep 30
 grpcurl -plaintext $NODES[2]:2379 chainfire.ClusterService/GetStatus
 ```
 **Expected**: Cluster survives single node failure, node rejoins
 ## Test Execution Order
 1. Service Health (basic connectivity)
 2. Cluster Formation (Raft quorum)
 3. IAM Auth (foundation for other tests)
 4. FlareDB Storage (data layer)
 5. Nightlight Metrics (observability)
 6. LightningSTOR S3 (object storage)
 7. FlashDNS (name resolution)
 8. FiberLB (load balancing)
 9. PrismNET (networking)
 10. CreditService (quota)
 11. Node Failure (resilience)
 ## Success Criteria
 - All services respond on all nodes
 - ChainFire cluster: 3 nodes, leader elected
 - FlareDB cluster: quorum formed, replication working
 - IAM: auth tokens issued/validated
 - Data: read/write across nodes
 - Metrics: targets up, queries working
 - LB: traffic distributed
 - Failover: survives 1 node loss
 ## Failure Handling
 If tests fail:
 1. Capture service logs: `journalctl -u <service> --no-pager`
 2. Document failure in evidence section
 3. Create follow-up task if systemic issue
 4. Do not proceed to production traffic

      HTTP server runs on port 8082 alongside gRPC (50052)
      Implementation notes:
      - KV operations use RdbClient.connect_direct() to self-connect to local gRPC server
      - SQL endpoints are placeholders due to Arc<Mutex<RdbClient>> state management complexity
      - Pattern follows ChainFire approach: HTTP REST wraps around core services

      - Common patterns (request/response format, authentication, multi-tenancy)
      - Detailed curl examples for all 7 services:
        * ChainFire (8081) - KV operations (get/put/delete/scan), cluster management
        * FlareDB (8082) - KV operations, SQL endpoints (placeholder)
        * IAM (8083) - Token operations (issue/verify), user management
        * PlasmaVMC (8084) - VM lifecycle (create/start/stop/delete/list)
        * k8shost (8085) - Pod/Service/Node management
        * CreditService (8086) - Wallet operations, transactions, reservations
        * PrismNET (8087) - VPC and Subnet management
      - Complete workflow examples:
        * Deploy VM with networking (VPC → Subnet → Credits → VM → Start)
        * Deploy Kubernetes pod with service
        * User authentication flow (create user → issue token → verify → use)
      - Debugging tips and scripts (health check all services, verbose curl)
      - Error handling patterns with HTTP status codes
      - Performance considerations (connection reuse, batch operations, parallelization)
      - Migration guide from gRPC to REST
      - References to planned OpenAPI specs and Postman collection
      This completes the user goal "curlで簡単に使える" (easy curl access).

+      Test Flow:
      1. Start 3 TCP backend servers (ports 18001-18003)
      2. Configure FiberLB with 1 LB, 1 pool, 3 backends (all Online)
      3. Start DataPlane listener on port 17080
      4. Send 15 client requests through load balancer
      5. Track which backend handled each request
      6. Verify perfect round-robin distribution (5-5-5)
      **Evidence:**
      - Test passed: fiberlb/crates/fiberlb-server/tests/integration.rs:315-458
      - Test runtime: 0.58s
      - Distribution: Backend 1: 5 requests, Backend 2: 5 requests, Backend 3: 5 requests
      - Perfect round-robin (15 total requests, 5 per backend)
      **Key Validations:**
      - DataPlane TCP proxy works end-to-end
      - Listener accepts connections on configured port
      - Backend selection uses round-robin algorithm
      - Traffic distributes evenly across all Online backends
      - Bidirectional proxying works (client ↔ LB ↔ backend)

 # T055.S2: L7 Load Balancing Design Specification
 **Author:** PeerA
 **Date:** 2025-12-12
 **Status:** DRAFT
 ## 1. Executive Summary
 This document specifies the L7 (HTTP/HTTPS) load balancing implementation for FiberLB. The design extends the existing L4 TCP proxy with HTTP-aware routing, TLS termination, and policy-based backend selection.
 ## 2. Current State Analysis
 ### 2.1 Existing L7 Type Foundation
 **File:** `fiberlb-types/src/listener.rs`
 ```rust
 pub enum ListenerProtocol {
    Tcp,              // L4
    Udp,              // L4
    Http,             // L7 - exists but unused
    Https,            // L7 - exists but unused
    TerminatedHttps,  // L7 - exists but unused
 }
 pub struct TlsConfig {
    pub certificate_id: String,
    pub min_version: TlsVersion,
    pub cipher_suites: Vec<String>,
 }
 ```
 **File:** `fiberlb-types/src/pool.rs`
 ```rust
 pub enum PoolProtocol {
    Tcp,   // L4
    Udp,   // L4
    Http,  // L7 - exists but unused
    Https, // L7 - exists but unused
 }
 pub enum PersistenceType {
    SourceIp,   // L4
    Cookie,     // L7 - exists but unused
    AppCookie,  // L7 - exists but unused
 }
 ```
 ### 2.2 L4 DataPlane Architecture
 **File:** `fiberlb-server/src/dataplane.rs`
 Current architecture:
 - TCP proxy using `tokio::net::TcpListener`
 - Bidirectional copy via `tokio::io::copy`
 - Round-robin backend selection (Maglev ready but not integrated)
 **Gap:** No HTTP parsing, no L7 routing rules, no TLS termination.
 ## 3. L7 Architecture Design

 |-----------|-----------|-----------|
 | HTTP Server | `axum` | Already in workspace, familiar API |
 | TLS | `rustls` via `axum-server` | Pure Rust, no OpenSSL dependency |
 | HTTP Client | `hyper` | Low-level control for proxy scenarios |
 | Connection Pool | `hyper-util` | Efficient backend connection reuse |
 **Alternative Considered:** Cloudflare Pingora
 - Pros: High performance, battle-tested
 - Cons: Heavy dependency, different paradigm, learning curve
 - Decision: Start with axum/hyper, consider Pingora for v2 if perf insufficient
 ## 4. New Types
 ### 4.1 L7Policy
 Content-based routing policy attached to a Listener.
 ```rust
 // File: fiberlb-types/src/l7policy.rs
 /// Unique identifier for an L7 policy
 #[derive(Debug, Clone, Copy, PartialEq, Eq, Hash, Serialize, Deserialize)]
 pub struct L7PolicyId(Uuid);
 /// L7 routing policy
 #[derive(Debug, Clone, Serialize, Deserialize)]
 pub struct L7Policy {
    pub id: L7PolicyId,
    pub listener_id: ListenerId,
    pub name: String,
    /// Evaluation order (lower = higher priority)

    /// Route to a specific pool
    RedirectToPool,
    /// Return HTTP redirect to URL

    Reject,
 }
 ```
 ### 4.2 L7Rule
 Match conditions for L7Policy evaluation.

    pub key: Option<String>,
    /// Invert the match result
    pub invert: bool,
    pub created_at: u64,
    pub updated_at: u64,
 }
 /// What to match against
 #[derive(Debug, Clone, Copy, PartialEq, Eq, Serialize, Deserialize)]

 pub enum L7RuleType {
    /// Match request hostname (Host header or SNI)
    HostName,
    /// Match request path
    Path,
    /// Match file extension (e.g., .jpg, .css)
    FileType,
    /// Match HTTP header value
    Header,
    /// Match cookie value
    Cookie,
    /// Match SSL SNI hostname
    SslConnSnI,
 }
 /// How to compare
 #[derive(Debug, Clone, Copy, PartialEq, Eq, Serialize, Deserialize)]
 #[serde(rename_all = "snake_case")]
 pub enum L7CompareType {
    /// Exact match

 ## 12. Dependencies
 Add to `fiberlb-server/Cargo.toml`:
 ```toml
 [dependencies]
 # HTTP/TLS
 axum = { version = "0.8", features = ["http2"] }
 axum-server = { version = "0.7", features = ["tls-rustls"] }
 hyper = { version = "1.0", features = ["full"] }
 hyper-util = { version = "0.1", features = ["client", "client-legacy", "http1", "http2"] }
 rustls = "0.23"
 rustls-pemfile = "2.0"
 tokio-rustls = "0.26"
 # Routing
 regex = "1.10"
 ```
 ## 13. Decision Summary
 | Aspect | Decision | Rationale |
 |--------|----------|-----------|
 | HTTP Framework | axum | Consistent with other services, familiar API |
 | TLS Library | rustls | Pure Rust, no OpenSSL complexity |

 # T055.S3: BGP Integration Strategy Specification
 **Author:** PeerA
 **Date:** 2025-12-12
 **Status:** DRAFT
 ## 1. Executive Summary
 This document specifies the BGP Anycast integration strategy for FiberLB to enable VIP (Virtual IP) advertisement to upstream routers. The recommended approach is a **sidecar pattern** using GoBGP with gRPC API integration.
 ## 2. Background
 ### 2.1 Current State
 - FiberLB binds listeners to `0.0.0.0:{port}` on each node
 - LoadBalancer resources have `vip_address` field (currently unused for routing)
 - No mechanism exists to advertise VIPs to physical network infrastructure
 ### 2.2 Requirements (from PROJECT.md Item 7)
 - "BGP AnycastによるL2ロードバランシング" (BGP Anycast L2 LB)
 - VIPs must be reachable from external networks
 - Support for ECMP (Equal-Cost Multi-Path) across multiple FiberLB nodes
 - Graceful withdrawal when load balancer is unhealthy/deleted
 ## 3. BGP Library Options Analysis
 ### 3.1 Option A: GoBGP Sidecar (RECOMMENDED)
 **Description:** Run GoBGP as a sidecar container/process, control via gRPC API
 | Aspect | Details |
 |--------|---------|
 | Language | Go |
 | Maturity | Production-grade, widely deployed |
 | API | gRPC with well-documented protobuf |
 | Integration | FiberLB calls GoBGP gRPC to add/withdraw routes |
 | Deployment | Separate process, co-located with FiberLB |
 **Pros:**
 - Battle-tested in production (Google, LINE, Yahoo Japan)
 - Extensive BGP feature support (ECMP, BFD, RPKI)
 - Clear separation of concerns
 - Minimal code changes to FiberLB
 **Cons:**
 - External dependency (Go binary)
 - Additional process management
 - Network overhead for gRPC calls (minimal)
 ### 3.2 Option B: RustyBGP Sidecar
 **Description:** Same sidecar pattern but using RustyBGP daemon
 | Aspect | Details |
 |--------|---------|
 | Language | Rust |
 | Maturity | Active development, less production deployment |
 | API | GoBGP-compatible gRPC |
 | Performance | Higher than GoBGP (multicore optimized) |
 **Pros:**
 - Rust ecosystem alignment
 - Drop-in replacement for GoBGP (same API)
 - Better performance in benchmarks
 **Cons:**
 - Less production history
 - Smaller community
 ### 3.3 Option C: Embedded zettabgp
 **Description:** Build custom BGP speaker using zettabgp library
 | Aspect | Details |
 |--------|---------|
 | Language | Rust |
 | Type | Parsing/composing library only |
 | Integration | Embedded directly in FiberLB |
 **Pros:**
 - No external dependencies
 - Full control over BGP behavior
 - Single binary deployment
 **Cons:**
 - Significant implementation effort (FSM, timers, peer state)
 - Risk of BGP protocol bugs
 - Months of additional development
 ### 3.4 Option D: OVN Gateway Integration
 **Description:** Leverage OVN's built-in BGP capabilities via OVN gateway router
 | Aspect | Details |
 |--------|---------|
 | Dependency | Requires OVN deployment |
 | Integration | FiberLB configures OVN via OVSDB |
 **Pros:**
 - No additional BGP daemon
 - Integrated with SDN layer
 **Cons:**
 - Tightly couples to OVN
 - Limited BGP feature set
 - May not be deployed in all environments
 ## 4. Recommended Architecture

 ```
 ### 4.1 Components
 1. **FiberLB Server** - Existing service, adds BGP client module
 2. **GoBGP Daemon** - BGP speaker process, controlled via gRPC
 3. **BGP Client Module** - New Rust module using `gobgp-client` crate or raw gRPC
 ### 4.2 Communication Flow
 1. LoadBalancer created with VIP address
 2. FiberLB checks backend health
 3. When healthy backends exist → `AddPath(VIP/32)`
 4. When all backends fail → `DeletePath(VIP/32)`
 5. LoadBalancer deleted → `DeletePath(VIP/32)`
 ## 5. Implementation Design
 ### 5.1 New Module: `fiberlb-bgp`
 ```rust
 // fiberlb/crates/fiberlb-bgp/src/lib.rs
 pub struct BgpManager {
    client: GobgpClient,
    config: BgpConfig,
    advertised_vips: HashSet<IpAddr>,
 }
 impl BgpManager {
    /// Advertise a VIP to BGP peers
    pub async fn advertise_vip(&mut self, vip: IpAddr) -> Result<()>;
    /// Withdraw a VIP from BGP peers
    pub async fn withdraw_vip(&mut self, vip: IpAddr) -> Result<()>;
    /// Check if VIP is currently advertised
    pub fn is_advertised(&self, vip: &IpAddr) -> bool;
 }
 ```
 ### 5.2 Configuration Schema
 ```yaml
 # fiberlb-server config
 bgp:
  enabled: true
  gobgp_address: "127.0.0.1:50051"  # GoBGP gRPC address
  local_as: 65001
  router_id: "10.0.0.1"
  neighbors:
    - address: "10.0.0.254"
      remote_as: 65000
      description: "ToR Router"
 ```
 ### 5.3 GoBGP Configuration (sidecar)
 ```yaml
 # /etc/gobgp/gobgp.yaml
 global:
  config:
    as: 65001
    router-id: 10.0.0.1
    port: 179
 neighbors:
  - config:
      neighbor-address: 10.0.0.254
      peer-as: 65000
    afi-safis:
      - config:
          afi-safi-name: ipv4-unicast
        add-paths:
          config:
            send-max: 8
 ```
 ### 5.4 Integration Points in FiberLB
 ```rust
 // In loadbalancer_service.rs
 impl LoadBalancerService {
    async fn on_loadbalancer_active(&self, lb: &LoadBalancer) {
        if let Some(vip) = &lb.vip_address {
            if let Some(bgp) = &self.bgp_manager {
                bgp.advertise_vip(vip.parse()?).await?;
            }
        }
    }
    async fn on_loadbalancer_deleted(&self, lb: &LoadBalancer) {
        if let Some(vip) = &lb.vip_address {
            if let Some(bgp) = &self.bgp_manager {
                bgp.withdraw_vip(vip.parse()?).await?;
            }
        }
    }
 }
 ```
 ## 6. Deployment Patterns
 ### 6.1 NixOS Module
 ```nix
 # modules/fiberlb-bgp.nix
 { config, lib, pkgs, ... }:
 {
  services.fiberlb = {
    bgp = {
      enable = true;
      localAs = 65001;
      routerId = "10.0.0.1";
      neighbors = [
        { address = "10.0.0.254"; remoteAs = 65000; }
      ];
    };
  };
  # GoBGP sidecar
  services.gobgpd = {
    enable = true;
    config = fiberlb-bgp-config;
  };
 }
 ```
 ### 6.2 Container/Pod Deployment
 ```yaml
 # kubernetes deployment with sidecar
 spec:
  containers:
    - name: fiberlb
      image: plasmacloud/fiberlb:latest
      env:
        - name: BGP_GOBGP_ADDRESS
          value: "localhost:50051"
    - name: gobgp
      image: osrg/gobgp:latest
      args: ["-f", "/etc/gobgp/config.yaml"]
      ports:
        - containerPort: 179  # BGP
        - containerPort: 50051  # gRPC
 ```
 ## 7. Health-Based VIP Withdrawal
 ### 7.1 Logic
 ```
 ┌─────────────────────────────────────────┐
 │          Health Check Loop              │
 │                                         │
 │  FOR each LoadBalancer WITH vip_address │
 │    healthy_backends = count_healthy()   │
 │                                         │
 │    IF healthy_backends > 0              │
 │      AND NOT advertised(vip)            │
 │    THEN                                 │
 │      advertise(vip)                     │
 │                                         │
 │    IF healthy_backends == 0             │
 │      AND advertised(vip)                │
 │    THEN                                 │
 │      withdraw(vip)                      │
 │                                         │
 └─────────────────────────────────────────┘
 ```
 ### 7.2 Graceful Shutdown
 1. SIGTERM received
 2. Withdraw all VIPs (allow BGP convergence)
 3. Wait for configurable grace period (default: 5s)
 4. Shutdown data plane
 ## 8. ECMP Support
 With multiple FiberLB nodes advertising the same VIP:
 ```
            ┌─────────────┐
            │  ToR Router │
            │ (AS 65000)  │
            └──────┬──────┘
                   │ ECMP
        ┌──────────┼──────────┐
        ▼          ▼          ▼
   ┌─────────┐ ┌─────────┐ ┌─────────┐
   │FiberLB-1│ │FiberLB-2│ │FiberLB-3│
   │ VIP: X  │ │ VIP: X  │ │ VIP: X  │
   │AS 65001 │ │AS 65001 │ │AS 65001 │
   └─────────┘ └─────────┘ └─────────┘
 ```
 - All nodes advertise same VIP with same attributes
 - Router distributes traffic via ECMP hashing
 - Node failure = route withdrawal = automatic failover
 ## 9. Future Enhancements
 1. **BFD (Bidirectional Forwarding Detection)** - Faster failure detection
 2. **BGP Communities** - Traffic engineering support
 3. **Route Filtering** - Export policies per neighbor
 4. **RustyBGP Migration** - Switch from GoBGP for performance
 5. **Embedded Speaker** - Long-term: native Rust BGP using zettabgp
 ## 10. Implementation Phases
 ### Phase 1: Basic Integration
 - GoBGP sidecar deployment
 - Simple VIP advertise/withdraw API
 - Manual configuration
 ### Phase 2: Health-Based Control
 - Automatic VIP withdrawal on backend failure
 - Graceful shutdown handling
 ### Phase 3: Production Hardening
 - BFD support
 - Metrics and observability
 - Operator documentation

 # T057.S1: IPAM System Design Specification
 **Author:** PeerA
 **Date:** 2025-12-12
 **Status:** DRAFT
 ## 1. Executive Summary
 This document specifies the IPAM (IP Address Management) system for k8shost integration with PrismNET. The design extends PrismNET's existing IPAM capabilities to support Kubernetes Service ClusterIP and LoadBalancer IP allocation.
 ## 2. Current State Analysis
 ### 2.1 k8shost Service IP Allocation (Current)
 **File:** `k8shost/crates/k8shost-server/src/services/service.rs:28-37`
 ```rust
 pub fn allocate_cluster_ip() -> String {
    // Simple counter-based allocation in 10.96.0.0/16
    static COUNTER: AtomicU32 = AtomicU32::new(100);
    let counter = COUNTER.fetch_add(1, Ordering::SeqCst);
    format!("10.96.{}.{}", (counter >> 8) & 0xff, counter & 0xff)
 }
 ```
 **Issues:**
 - No persistence (counter resets on restart)
 - No collision detection
 - No integration with network layer
 - Hard-coded CIDR range
 ### 2.2 PrismNET IPAM (Current)
 **File:** `prismnet/crates/prismnet-server/src/metadata.rs:577-662`
 **Capabilities:**
 - CIDR parsing and IP enumeration
 - Allocated IP tracking via Port resources
 - Gateway IP avoidance
 - Subnet-scoped allocation
 - ChainFire persistence
 **Limitations:**
 - Designed for VM/container ports, not K8s Services
 - No dedicated Service IP subnet concept
 ## 3. Architecture Design
 ### 3.1 Conceptual Model

 ```
 ### 3.2 New Resource: ServiceIPPool
 A dedicated IP pool for Kubernetes Services within a tenant.
 ```rust
 /// Service IP Pool for k8shost Service allocation
 pub struct ServiceIPPool {
    pub id: ServiceIPPoolId,
    pub org_id: String,
    pub project_id: String,
    pub name: String,
    pub cidr_block: String,        // e.g., "10.96.0.0/16"
    pub pool_type: ServiceIPPoolType,
    pub allocated_ips: HashSet<String>,
    pub created_at: u64,
    pub updated_at: u64,
 }
 pub enum ServiceIPPoolType {
    ClusterIP,      // For ClusterIP services
    LoadBalancer,   // For LoadBalancer services (VIPs)
    NodePort,       // Reserved NodePort range
 }
 ```

 ```
 ## 4. API Design
 ### 4.1 PrismNET IPAM gRPC Service
 ```protobuf
 service IpamService {
  // Create a Service IP Pool
  rpc CreateServiceIPPool(CreateServiceIPPoolRequest)
    returns (CreateServiceIPPoolResponse);
  // Get Service IP Pool
  rpc GetServiceIPPool(GetServiceIPPoolRequest)
    returns (GetServiceIPPoolResponse);
  // List Service IP Pools
  rpc ListServiceIPPools(ListServiceIPPoolsRequest)
    returns (ListServiceIPPoolsResponse);
  // Allocate IP from pool
  rpc AllocateServiceIP(AllocateServiceIPRequest)
    returns (AllocateServiceIPResponse);
  // Release IP back to pool
  rpc ReleaseServiceIP(ReleaseServiceIPRequest)
    returns (ReleaseServiceIPResponse);
  // Get IP allocation status
  rpc GetIPAllocation(GetIPAllocationRequest)
    returns (GetIPAllocationResponse);
 }
 message AllocateServiceIPRequest {
  string org_id = 1;
  string project_id = 2;
  string pool_id = 3;            // Optional: specific pool
  ServiceIPPoolType pool_type = 4; // Required: ClusterIP or LoadBalancer
  string service_uid = 5;        // K8s service UID for tracking
  string requested_ip = 6;       // Optional: specific IP request
 }
 message AllocateServiceIPResponse {
  string ip_address = 1;
  string pool_id = 2;
 }
 ```
 ### 4.2 k8shost IpamClient
 ```rust
 /// IPAM client for k8shost
 pub struct IpamClient {
    client: IpamServiceClient<Channel>,
 }
 impl IpamClient {
    /// Allocate ClusterIP for a Service
    pub async fn allocate_cluster_ip(
        &mut self,
        org_id: &str,
        project_id: &str,
        service_uid: &str,
    ) -> Result<String>;
    /// Allocate LoadBalancer IP for a Service
    pub async fn allocate_loadbalancer_ip(
        &mut self,
        org_id: &str,
        project_id: &str,
        service_uid: &str,
    ) -> Result<String>;
    /// Release an allocated IP
    pub async fn release_ip(
        &mut self,
        org_id: &str,
        project_id: &str,
        ip_address: &str,
    ) -> Result<()>;
 }
 ```
 ## 5. Storage Schema
 ### 5.1 ChainFire Key Structure
 ```
 /prismnet/ipam/pools/{org_id}/{project_id}/{pool_id}
 /prismnet/ipam/allocations/{org_id}/{project_id}/{ip_address}
 ```
 ### 5.2 Allocation Record
 ```rust
 pub struct IPAllocation {
    pub ip_address: String,
    pub pool_id: ServiceIPPoolId,
    pub org_id: String,
    pub project_id: String,
    pub resource_type: String,    // "k8s-service", "vm-port", etc.
    pub resource_id: String,      // Service UID, Port ID, etc.
    pub allocated_at: u64,
 }
 ```
 ## 6. Implementation Plan
 ### Phase 1: PrismNET IPAM Service (S1 deliverable)
 1. Add `ServiceIPPool` type to prismnet-types
 2. Add `IpamService` gRPC service to prismnet-api
 3. Implement `IpamServiceImpl` in prismnet-server
 4. Storage: pools and allocations in ChainFire
 ### Phase 2: k8shost Integration (S2)
 1. Create `IpamClient` in k8shost
 2. Replace `allocate_cluster_ip()` with PrismNET call
 3. Add IP release on Service deletion
 4. Configuration: PrismNET endpoint env var
 ### Phase 3: Default Pool Provisioning
 1. Auto-create default ClusterIP pool per tenant
 2. Default CIDR: `10.96.{tenant_hash}.0/20` (4096 IPs)
 3. LoadBalancer pool: `192.168.{tenant_hash}.0/24` (256 IPs)
 ## 7. Tenant Isolation
 ### 7.1 Pool Isolation
 Each tenant (org_id + project_id) has:
 - Separate ClusterIP pool
 - Separate LoadBalancer pool
 - Non-overlapping IP ranges
 ### 7.2 IP Collision Prevention
 - IP uniqueness enforced at pool level
 - CAS (Compare-And-Swap) for concurrent allocation
 - ChainFire transactions for atomicity
 ## 8. Default Configuration
 ```yaml
 # k8shost config
 ipam:
  enabled: true
  prismnet_endpoint: "http://prismnet:9090"
  # Default pools (auto-created if missing)
  default_cluster_ip_cidr: "10.96.0.0/12"   # 1M IPs shared
  default_loadbalancer_cidr: "192.168.0.0/16"  # 64K IPs shared
  # Per-tenant allocation
  cluster_ip_pool_size: "/20"    # 4096 IPs per tenant
  loadbalancer_pool_size: "/24"  # 256 IPs per tenant
 ```
 ## 9. Backward Compatibility
 ### 9.1 Migration Path
 1. Deploy new IPAM service in PrismNET
 2. k8shost checks for IPAM availability on startup
 3. If IPAM unavailable, fall back to local counter
 4. Log warning for fallback mode
 ### 9.2 Existing Services
 - Existing Services retain their IPs
 - On next restart, k8shost syncs with IPAM
 - Conflict resolution: IPAM is source of truth
 ## 10. Observability
 ### 10.1 Metrics
 ```
 # Pool utilization
 prismnet_ipam_pool_total{org_id, project_id, pool_type}
 prismnet_ipam_pool_allocated{org_id, project_id, pool_type}
 prismnet_ipam_pool_available{org_id, project_id, pool_type}
 # Allocation rate
 prismnet_ipam_allocations_total{org_id, project_id, pool_type}
 prismnet_ipam_releases_total{org_id, project_id, pool_type}
 ```
 ### 10.2 Alerts
 - Pool exhaustion warning at 80% utilization
 - Allocation failure alerts
 - Pool not found errors
 ## 11. References

 - [OpenStack Neutron IPAM](https://docs.openstack.org/neutron/latest/admin/intro-os-networking.html)

 ## 12. Decision Summary
 | Aspect | Decision | Rationale |
 |--------|----------|-----------|
 | IPAM Location | PrismNET | Network layer owns IP management |
 | Storage | ChainFire | Consistency with existing PrismNET storage |
 | Pool Type | Per-tenant | Tenant isolation, quota enforcement |
 | Integration | gRPC client | Consistent with other PlasmaCloud services |
 | Fallback | Local counter | Backward compatibility |

      **Implementation Complete (1,030 LOC)**
      PrismNET IPAM (730 LOC):
      ✅ ServiceIPPool types with CIDR + HashSet allocation tracking
      ✅ IPAM proto definitions (6 RPCs: Create/Get/List pools, Allocate/Release/Get IPs)
      ✅ IpamService gRPC implementation with next-available-IP algorithm
      ✅ ChainFire metadata storage (6 methods)
      ✅ Registered in prismnet-server main.rs
      k8shost Integration (150 LOC):
      ✅ IpamClient gRPC wrapper
      ✅ ServiceServiceImpl updated to use IPAM (allocate on create, release on delete)
      ✅ PrismNetConfig added to k8shost config
      ✅ Tests updated
      Technical highlights:
      - Tenant isolation via (org_id, project_id) scoping
      - IPv4 CIDR enumeration (skips network/broadcast, starts at .10)
      - Auto-pool-selection by type (ClusterIp/LoadBalancer/NodePort)
      - Best-effort IP release on service deletion
      - ChainFire persistence with JSON serialization

      - k8shost → IpamClient → PrismNET IpamService
      - PrismNET stores pools in /prismnet/ipam/pools/{org}/{proj}/{pool}
      - Allocations tracked in /prismnet/ipam/allocations/{org}/{proj}/{ip}
      Implementation phases:
      1. PrismNET IpamService (new gRPC service)
      2. k8shost IpamClient integration
      3. Default pool auto-provisioning

  **User Direction (2025-12-13 00:46 JST):**
  Three-layer architecture with separate Nix-NOS repo:
  **Layer 1 (T062):** Nix-NOS generic network module (separate repo)
  **Layer 2 (T061):** PlasmaCloud Network - FiberLB BGP, PrismNET integration
  **Layer 3 (T061):** PlasmaCloud Cluster - cluster-config, Deployer, orchestration
  **Key Principle:**
  PlasmaCloud modules DEPEND ON Nix-NOS, not the other way around.
  Nix-NOS remains generic and reusable by other projects.
  **Repository:** github.com/centra/plasmacloud (existing repo)
  **Path:** nix/modules/plasmacloud-*.nix
 acceptance:
  - plasmacloud.cluster defines node topology and generates cluster-config.json
  - plasmacloud.network uses nix-nos.bgp for FiberLB VIP advertisement

  **User Decision (2025-12-13 00:46 JST):**
  Separate Nix-NOS as generic network module in its own repository.
  **Three-Layer Architecture:**
  - Layer 1: Nix-NOS (generic) - BGP, VLAN, systemd-networkd, routing
  - Layer 2: PlasmaCloud Network - FiberLB BGP, PrismNET integration
  - Layer 3: PlasmaCloud Cluster - cluster-config, Deployer, service orchestration
  **Key Principle:**
  Nix-NOS should NOT know about PlasmaCloud, FiberLB, ChainFire, etc.
  It's a generic network configuration system usable by anyone.
  **Repository:** github.com/centra/nix-nos (new, separate from plasmacloud)
 acceptance:
  - Standalone flake.nix that works independently
  - BGP module with BIRD2 and GoBGP backends
  - Network interface abstraction via systemd-networkd
  - VLAN support
  - Example configurations for non-PlasmaCloud use cases
  - PlasmaCloud can import as flake input
