fix(k3s): route audit logs through journald, codify etcd member recovery

Two changes prompted by today's etcd raft panic on worker1-k8s0 (tocommit out of range, lost-write on follower) and the cascading disk pressure that surfaced underneath it. Audit logs to journald - kube-apiserver now uses audit-log-path=- so audit events flow to k3s.service stdout and into journald instead of growing files in /var/log/kubernetes. The previous setup combined apiserver's internal rotation with a logrotate *.log glob that double-rotated the rotated files into permanent orphans (observed: 7+ GB). - New journald-limits operation writes a SystemMaxUse=2G drop-in so audit volume cannot fill /var/log even under bursty load. - log-rotation operation repurposed to decommission the obsolete logrotate rule and reap leftover audit files. Idempotent: no-op on fresh installs. Etcd member recovery - New recoverEtcdMember(broken, peer, hostname) codifies the documented k3s recovery: stop k3s, etcdctl member remove, wipe /var/lib/rancher/k3s/server/{db,tls,cred}, restart, poll for rejoin. Refuses to operate when cluster size < 3 to preserve quorum. Tests - 7 new unit tests covering both decommission paths and the recovery procedure (54 total, all green). - install.test.ts asserts the file-based audit args are gone.

+## Skill routing
+
+When the user's request matches an available skill, ALWAYS invoke it using the Skill
+tool as your FIRST action. Do NOT answer directly, do NOT use other tools first.
+The skill has specialized workflows that produce better results than ad-hoc answers.
+
+Key routing rules:
+- Product ideas, "is this worth building", brainstorming → invoke gstack-office-hours
+- Bugs, errors, "why is this broken", 500 errors → invoke gstack-investigate
+- Ship, deploy, push, create PR → invoke gstack-ship
+- QA, test the site, find bugs → invoke gstack-qa
+- Code review, check my diff → invoke gstack-review
+- Update docs after shipping → invoke gstack-document-release
+- Weekly retro → invoke gstack-retro
+- Design system, brand → invoke gstack-design-consultation
+- Visual audit, design polish → invoke gstack-design-review
+- Architecture review → invoke gstack-plan-eng-review
+- Save progress, checkpoint, resume → invoke gstack-checkpoint

+# TODOS
+
+## P1 — Ship with Phase 1
+
+### v2.0 Architecture Document Update
+Update `bastion/docs/ARCHITECTURE.md` to cover v2.0: driver model, fleet system,
+Pulumi integration, Vault secrets, Deno evaluator, new CLI grammar. The existing
+doc covers v1.0 comprehensively (432 lines). v2.0 adds 5+ major subsystems.
+**Effort:** M (human: 1 week / CC: 1-2 days)
+**Depends on:** Phase 1 complete
+**Source:** CEO review 2026-04-01
+
+## P2 — Post-v2.0 Core
+
+### SSH Emergency Mode (scoped)
+SSH-based operations limited to: (1) earliest necessary box provisioning before agent
+is installed, and (2) emergency debugging/fixing operations that can't be done via agent.
+NOT a general-purpose DeploymentTarget alternative. The v1.0 `recheck` and `fix-ssh-root.sh`
+patterns are the model. Agent stays the primary management path.
+**Effort:** S (human: 1 week / CC: 1 day)
+**Depends on:** Phase 2 complete (DeploymentTarget interface exists)
+**Source:** CEO review 2026-04-01
+
+### Prometheus Metrics Endpoint
+Add `/metrics` endpoint to labd: resource counts by status, apply duration histograms,
+driver operation latency, fleet pipeline completion rates. Standard Prometheus scraping
+for Grafana dashboards and alerting.
+**Effort:** S (human: 2-3 days / CC: 2-3 hours)
+**Depends on:** Phase 1 (labd exists with resource store)
+**Source:** CEO review 2026-04-01 (observability gap)
+
+## P3 — Future Enhancements
+
+### Infrastructure Graph Visualization
+Visual representation of resource dependencies, environment topology, fleet status.
+Could be a web UI or terminal-based (like `kubectl tree`).
+**Source:** CEO review 2026-04-01
+
+### `labctl import` for Existing Cloud Resources
+Discover and import existing AWS/GCP resources into the state store.
+Pulumi's import functionality could be leveraged.
+**Source:** CEO review 2026-04-01
+
+### Built-in Secrets Rotation
+Automatic rotation of managed secrets (database passwords, API keys).
+Vault handles rotation but a labctl-native workflow could simplify.
+**Source:** CEO review 2026-04-01

+# Lab Platform Architecture
+
+## Overview
+
+A bare-metal and hybrid cloud infrastructure platform for automated machine provisioning, Kubernetes cluster management, and fleet operations. The platform discovers hardware via PXE boot, installs operating systems unattended, deploys k3s clusters, and provides centralized management through a CLI and API.
+
+**Components:**
+- **bastion** -- PXE boot server (DHCP/TFTP/HTTP) for machine discovery and OS installation
+- **labd** -- Master daemon for multi-bastion aggregation, persistent state, agent management
+- **labctl** -- CLI tool for operators (kubectl-style interface)
+- **lab-agent** -- Daemon on provisioned servers for remote execution and monitoring
+- **modules** -- Declarative configuration system (k3s, labcontroller)
+
+---
+
+## Architecture
+
+```
+                           labctl (CLI)
+                               |
+                        labd (master daemon)
+                        /    |    \
+                  bastion1  bastion2  ...     (PXE provisioning)
+                    /   \      |
+              [machines]  [machines]           (bare metal)
+                  |           |
+              lab-agent   lab-agent            (remote exec)
+```
+
+### Communication Patterns
+
+| Path | Protocol | Auth |
+|------|----------|------|
+| labctl -> labd | HTTP/HTTPS | mTLS cert (future: token) |
+| bastion -> labd | WebSocket | Join token enrollment |
+| lab-agent -> labd | WebSocket | mTLS certificate |
+| machine -> bastion | HTTP | None (local network) |
+| Anaconda -> bastion | HTTP + UDP syslog | None (install-time) |
+| labctl -> bastion | HTTP | None (standalone mode) |
+
+### Standalone vs Centralized
+
+The bastion can operate in two modes:
+
+1. **Standalone** -- single bastion, state in local JSON file, CLI talks directly to bastion HTTP API
+2. **Centralized** -- bastion registers with labd via WebSocket, state aggregated in CockroachDB, CLI talks to labd which routes commands to the correct bastion
+

+
+## Packages
+
+### Monorepo Structure
+
+TypeScript ESM monorepo with pnpm workspaces. Six packages:
+
+| Package | Role | Key Tech |
+|---------|------|----------|
+| `@lab/shared` | Types, protocol, constants | - |
+| `@lab/bastion` | PXE server | Fastify, dnsmasq |
+| `@lab/cli` | CLI binary | Commander.js |
+| `@lab/labd` | Master daemon | Fastify, Prisma, CockroachDB |
+| `@lab/agent` | Server agent | WebSocket |
+| `@lab/modules` | Config modules | SSH, k8s-client |
+
+### @lab/shared
+
+Core type system shared by all packages.
+
+**State Model:**
+```typescript
+interface BastionState {
+  discovered:    Record<MAC, HardwareInfo>
+  install_queue: Record<MAC, InstallConfig>
+  installed:     Record<MAC, InstalledInfo>
+  debug:         Record<MAC, DebugConfig>
+}
+```
+
+**Roles:**
+- `vanilla` -- OS only, no k3s, no cluster services
+- `worker` -- k3s agent + Longhorn storage (joins existing cluster)
+- `infra` -- k3s server + etcd (control plane node)
+- `labcontroller` -- infra + bastion + labd + CockroachDB (self-sufficient)
+
+**OS Support:**
+- `fedora-43` -- Anaconda kickstart installer
+- `ubuntu-26.04` -- cloud-init autoinstall
+
+**Protocol:** Discriminated union message types for WebSocket communication between agents, bastions, and labd. Type guards and parsers for runtime validation.
+
+### @lab/bastion
+
+PXE boot server that handles the physical provisioning lifecycle.
+
+**Services:**
+- `StateManager` -- JSON file persistence with immutable update pattern
+- `SyslogListener` -- UDP syslog receiver (port 5514) for Anaconda install logs
+- `InstallLogBuffer` -- In-memory ring buffer + disk persistence per machine
+- `BastionConnection` -- WebSocket client to labd for centralized mode
+- dnsmasq management (spawn, config generation, proxy/full DHCP)
+- Network auto-detection (interface, IP, subnet, gateway)
+- ISO builder (xorriso + mtools for non-PXE machines)
+
+**HTTP Routes:**
+
+| Endpoint | Purpose |
+|----------|---------|
+| `GET /dispatch?mac=` | Dynamic iPXE script (discover/install/debug/local-boot) |
+| `GET /ks?mac=` | Per-machine Anaconda kickstart |
+| `GET /debug.ks` | Rescue mode kickstart |
+| `GET /debug-setup.sh` | nc listener setup script for rescue shell |
+| `GET /discover.ks` | Hardware discovery kickstart |
+| `POST /api/discover` | Hardware inventory report |
+| `POST /api/install` | Queue machine for install |
+| `POST /api/progress` | Install progress callback |
+| `POST /api/log` | Raw log line ingestion |
+| `POST /api/debug` | Queue debug/rescue mode |
+| `GET /api/machines` | List all machines |
+| `GET /api/logs/:mac` | Install logs + progress |
+| `GET /api/logs/:mac/follow` | SSE stream of progress events |
+| `DELETE /api/machines/:mac` | Forget machine |
+
+**Templates:**
+- `boot.ipxe.ts` -- iPXE scripts for each boot mode (discover, install, debug, pxe-boot-debug, local-boot)
+- `install.ks.ts` -- Full Fedora kickstart with LVM, SSH, k3s prereqs, progress callbacks, SysRq keys
+- `debug.ks.ts` -- Minimal rescue kickstart (SSH via inst.sshd)
+- `ubuntu-autoinstall.ts` -- cloud-init for Ubuntu
+- `dnsmasq.conf.ts` -- DHCP/TFTP configuration
+
+**Boot Dispatch Logic:**
+```
+1. debug[mac]?        -> renderDebugIpxe (auto-clear after serving)
+2. install_queue[mac]? -> renderInstallIpxe
+3. installed[mac]?    -> renderLocalBootIpxe (exit to disk)
+4. unknown            -> renderDiscoverIpxe
+```
+
+### @lab/labd
+
+Central management daemon. Aggregates multiple bastions, stores persistent state in CockroachDB, relays commands, manages agent fleet.
+
+**Database (Prisma + CockroachDB):**
+- `Server` -- hostname, MAC, IP, role, status, cloud, environment, labels
+- `Bastion` -- hostname, network, serverIp, lastHeartbeat
+- `Agent` -- certificate, enrollment, heartbeat
+- `Cluster` -- name, cloud, environment, kubeconfig (encrypted)
+- `User` / `Role` / `Permission` -- RBAC (action:cloud:env:server matrix)
+- `JoinToken` -- one-time/reusable enrollment tokens
+- `AuditLog` -- action, resource, result, timestamp
+
+**Key Services:**
+- `BastionRegistry` -- in-memory registry of connected bastions, state aggregation, MAC-to-bastion routing
+- `AgentRegistry` -- connected agents, heartbeat tracking
+- `MessageRouter` -- command relay between CLI/agents and bastions
+
+**Command Routing:**
+```
+CLI: labctl provision install <mac> <hostname>
+  -> POST /api/machines/install
+  -> labd finds bastion that knows this MAC
+  -> WebSocket: {type: "command-install", mac, hostname, disk, role}
+  -> bastion updates install_queue
+  -> WebSocket: {type: "command-response", status: "ok"}
+  -> HTTP response to CLI
+```
+
+### @lab/cli (labctl)
+
+Operator CLI. Commander.js binary, distributed as RPM/DEB or standalone bun-compiled executable.
+
+**Command Groups:**
+
+```

+
+**Key Features:**
+- Target resolution: hostname, MAC, or IP -> machine lookup
+- SSH reboot into PXE for reprovision/debug (efibootmgr --bootnext)
+- Follow mode: `labctl provision logs <target> -f` (5s polling)
+- Shell completions: bash, fish
+
+### @lab/modules
+
+Declarative configuration modules with three-phase lifecycle: install -> configure -> health.
+
+**k3s Module:**
+- 5 operation groups: host-prep, networking, k3s-server, k3s-agent, hardening
+- 15+ individual operations: kernel modules, sysctl, firewall, Cilium CNI, SELinux, audit policy, pod security, cert checks
+- Health checks: service running, node ready, API health, pod status, Cilium status, secrets encryption
+- SSH execution backend with progress callbacks
+
+### @lab/agent
+
+Daemon on provisioned servers. WebSocket to labd for:
+- Heartbeat (hostname, uptime, CPU/mem usage)
+- Command execution (with stdout/stderr streaming)
+- Log streaming (journalctl relay)
+- mTLS certificate enrollment and rotation
+
+---
+
+## Disk Layout
+
+### LVM Partitioning (labvg)
+
+All roles share a common LVM layout. The kickstart `%pre` auto-detects the install disk (NVMe preferred, then SATA, skipping USB/removable).
+
+| Volume | Size | FS | Reprovision |
+|--------|------|-----|-------------|
+| `/boot/efi` | 600 MB | vfat | Reused |
+| `/boot` | 3 GB | ext4 | Reused |
+| `swap` | 27 GB | swap | Recreated |
+| `/` (root) | 33 GB | xfs | Recreated |
+| `/var` | 100 GB | xfs | Recreated |
+| `/var/log` | 10 GB | xfs | Recreated |
+| `/home` | 10 GB | xfs | **Preserved** |
+| `/srv` | 20 GB | xfs | **Preserved** |
+| `/var/lib/longhorn` | remaining | xfs | **Preserved** (worker) |
+| `/var/lib/rancher` | 20 GB | xfs | **Preserved** (infra) |
+| `/tmp` | 4 GB | tmpfs | - |
+
+Reprovision detection: if `labvg` VG exists, reuse EFI/boot partitions and preserve data volumes.
+
+---
+
+## Kickstart Features
+
+The Fedora kickstart template (`install.ks.ts`) includes:
+
+- **Dynamic disk detection** -- `%pre` probes NVMe/SATA/virtio, skips USB/removable, supports both fresh install and reprovision
+- **Progress callbacks** -- `curl -sf POST /api/progress` at each stage (partitioning, post-install substeps, complete)
+- **Anaconda syslog forwarding** -- `logging --host --port` streams real-time install logs to bastion
+- **SSH hardening** -- key-only auth, root login via pubkey only, admin user with passwordless sudo
+- **Network-first boot order** -- `efibootmgr` reorders boot entries so PXE is always first (bastion controls every reboot)
+- **SysRq magic keys** -- `kernel.sysrq=1` for emergency reboot via KVM keyboard
+- **Role-specific setup:**
+  - `vanilla`: chronyd only
+  - `worker`/`infra`: kernel modules (br_netfilter, overlay), sysctl (ip_forward, inotify), firewalld disabled, k3s binary installed
+  - `infra`: k3s server binary pre-installed
+
+**What is NOT in the kickstart:**
+- `console=ttyS0` -- causes 30s-per-step boot timeout on hardware without physical serial UART (discovered 2026-03-30, see docs/pxe-boot-debugging-2026-03-30.md)
+- Background log streamer (`tail -f`) -- prevents Anaconda from syncing filesystem, causes %post writes to not persist
+
+---
+
+## Deployment
+
+### Container Images
+
+**bastion** (`Dockerfile.bastion`):
+- Base: Fedora 43 (needs dnsmasq, iPXE)
+- Multi-stage: Alpine build -> Fedora runtime
+- iPXE rebuilt from source (SNP driver for EFI)
+- hostNetwork in k8s (DHCP needs raw sockets)
+- Capabilities: NET_ADMIN, NET_RAW
+
+**labd** (`Dockerfile.labd`):
+- Base: Alpine (minimal)
+- Multi-stage build with Prisma client generation
+- Runs as non-root `node` user
+
+### Kubernetes (k3s)
+
+```
+Namespace: lab-infra
+  Deployment: bastion (hostNetwork, PVC for /data, host SSH keys)
+  ConfigMap: bastion-config (env vars)
+  Secret: bastion-join-token
+  PVC: bastion-state (local-path)
+
+Namespace: lab-system
+  Deployment: labd
+  Service: labd (NodePort 30100)
+  StatefulSet: cockroachdb-0
+```
+
+### CLI Distribution
+
+Built with `nfpm` as RPM/DEB. Includes:
+- `/usr/bin/labctl` (bun-compiled standalone binary)
+- `/usr/share/bash-completion/completions/labctl`
+- `/usr/share/fish/vendor_completions.d/labctl.fish`
+
+Config: `~/.labctl/config.yaml` with `labdUrl`, output format, default cloud/environment.

+## Build & Release
+
+```bash
+# Development
+pnpm install && pnpm build      # Compile all packages
+pnpm test:run                    # Unit tests (vitest)
+npx tsc --noEmit                 # Type check
+
+# Deploy
+bash scripts/deploy.sh all       # Build containers + RPM, push, restart pods
+bash scripts/deploy.sh bastion   # Just bastion
+bash scripts/deploy.sh labd      # Just labd
+bash scripts/deploy.sh labctl    # Just CLI (local RPM install)
+
+# Container builds
+bash scripts/build-bastion.sh --platforms linux/amd64 --push latest
+bash scripts/build-labd.sh --platforms linux/amd64 --push latest
+bash scripts/build-rpm.sh        # RPM + DEB packages
+
+# Integration tests (require libvirt, sudo)
+sudo tests/integration/run-pxe-test.sh
+```
+
+Registry: `mysources.co.uk` (Gitea at 10.0.0.194:3012)
+
+---
+
+## Testing
+
+### Unit Tests
+- Kickstart rendering (ksvalidator syntax check, partition layout, role-specific sections)
+- State management (load, save, update, debug field)
+- Dispatch routing (correct iPXE script for each machine state)
+- Syslog listener (UDP receive, IP->MAC resolution, RFC 3164 parsing)
+
+### Integration Tests (libvirt VMs)
+- **pxe-provision.test.ts** -- Full end-to-end: create VM -> PXE discovery -> queue install -> Anaconda install -> SSH verification -> systemd health -> SELinux enforcing -> boot order check
+- **iso-provision.test.ts** -- ISO boot for non-PXE machines
+- **k3s-single-node.test.ts** -- Post-provision k3s installation and health
+- VM screenshot capture during boot for debugging
+
+---
+
+## Security
+
+- **mTLS** for agent-labd communication (certificate enrollment via join tokens)
+- **SSH key-only auth** on provisioned machines (no password auth)
+- **SELinux enforcing** verified in integration tests
+- **RBAC** (planned): action:cloud:environment:server permission matrix
+- **Audit logging** (planned): every mutation tracked in CockroachDB
+- **Network-first boot order** prevents machines from booting without bastion approval
+- **SysRq keys** enabled for emergency reboot without SSH access
+
+---
+
+## Known Issues & Lessons Learned
+
+### Serial Console Boot Delay (2026-03-30)
+`console=ttyS0,115200n8` in kernel cmdline causes 30-second timeout at every systemd boot phase on hardware without a physical serial UART. Root cause: systemd blocks writing to non-existent UART. Fix: removed from kickstart entirely.
+
+### Anaconda %post Log Streamer
+Background `tail -f` in kickstart `%post` prevents Anaconda from syncing the filesystem. All file writes in %post appear to succeed but are lost on reboot. Fix: removed background log streamer, replaced with Anaconda's built-in `logging --host --port` syslog forwarding.
+
+### Disk Auto-Detection
+Hardcoded `/dev/sda` default broke NVMe-only machines. Fix: default to empty string (auto-detect) which triggers the `%pre` disk probe logic.
+
+### Anaconda Rescue Mode Limitations
+`%pre` and `%post` sections do not execute in `inst.rescue` mode. SSH in rescue mode is provided by Anaconda's `inst.sshd` kernel parameter + `sshpw` kickstart directive. Manual setup via `curl bastion:8080/debug-setup.sh | bash` for nc listener.
+
+---
+
+## Planned Work (Taskmaster)
+
+13 tasks in queue, all pending:
+
+1. **#72** Expand Prisma schema with resource relationships (Network, ServerNic, ServerDisk, ClusterMember)
+2. **#73** State persistence service (bastion state -> CockroachDB)
+3. **#74** State loading from labd on bastion startup
+4. **#75** Fix bastion --dir env var default
+5. **#76** Resource type registry with aliases (kubectl-style)
+6. **#77** `labctl get <resource>` command
+7. **#78** `labctl describe <resource>` command
+8. **#79** `labctl create/delete` commands
+9. **#80** Refactor provision commands to kubectl-style
+10. **#81** Server and resource API endpoints in labd
+11. **#82** RBAC permission checks in CLI
+12. **#83** Audit logging for resource operations
+13. **#84** Update CLI entry point and help text
+
+Additional items not in taskmaster:
+- Ubuntu autoinstall disk auto-detect (still defaults to /dev/sda)
+- Verify `inst.sshd` works end-to-end in rescue mode
+- k3s cluster join vs new cluster distinction in `labctl app k3s install`
+- arm64 container build (iPXE cross-compilation broken)

+// Validation tests for Asahi provisioning artifacts.
+//
+// Tests that can run WITHOUT Apple Silicon hardware:
+//   1. Shellcheck the generated firstboot script
+//   2. Verify the built rootfs ZIP structure
+//   3. Mount the rootfs and verify injected files
+//   4. Validate installer_data.json against the Asahi installer's Python parser
+//   5. Verify partition layout arithmetic
+//
+// Prerequisites:
+//   - Run scripts/build-asahi-rootfs.sh first (creates asahi-repo/)
+//   - shellcheck installed (dnf install ShellCheck)
+//   - python3 installed
+//   - root for loop mount (sudo)
+//
+// Run: sudo pnpm run test:integration:asahi-validate
