+## Enrollment Endpoints
+
+Enrollment endpoints enable new hosts to register with the Patch Manager and receive mTLS certificates for authenticated API access. These endpoints operate **without client certificate authentication** — security is enforced through rate limiting, single-use tokens, and admin approval workflows.
+
+**Base path:** `/api/v1/` (on the Patch Manager server)
+**Authentication:** None (pre-provisioning phase)
+**Transport:** HTTPS recommended; TLS verification intentionally relaxed on initial connection per security model
+
+> **Cross-reference:** [SPEC.md §4.2 Enrollment Workflow](./SPEC.md) · [DEPLOYMENT_SECURITY_GUIDE.md](./DEPLOYMENT_SECURITY_GUIDE.md)
+
+---
+
+### POST /api/v1/enroll
+
+**Description:** Initiates a host self-enrollment request with the Patch Manager. The manager assigns a unique polling token that the host uses to check approval status.
+
+**Authentication:** None (unauthenticated public endpoint)
+
+#### Request Body
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `machine_id` | string | Yes | Linux machine-id from `/etc/machine-id` |
+| `fqdn` | string | Yes | Fully qualified domain name of the host |
+| `ip_address` | string | Yes | Primary non-loopback IPv4 address |
+| `os_details` | object | Yes | OS metadata (free-form JSON object) |
+| `hostname` | string | No | Short hostname (without domain). Used by the manager to populate `display_name` on approval. If omitted, the manager falls back to the FQDN. |

+### GET /api/v1/enroll/status/{token}
+
+**Description:** Returns the current approval status of an enrollment request. When approved, the response includes the complete PKI bundle (CA certificate, server certificate, and server private key) needed for mTLS provisioning.
+
+**Authentication:** None (token serves as bearer credential)
+
+#### Path Parameters
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `token` | string | 64-character alphanumeric polling token from `POST /enroll` response |
+
+#### Response Format
+
+The endpoint returns a **tagged JSON object** with a `status` discriminator field. All responses return HTTP `200 OK` — the `status` value determines the outcome.
+
+##### Pending (Awaiting Admin Approval)
+
+```json
+{ "status": "pending" }
+```
+
+The enrollment request has been received and is awaiting administrator review. The host should continue polling at regular intervals.
+
+##### Approved (PKI Bundle Provided)
+
+```json
+{
+  "status": "approved",
+  "ca_crt": "-----BEGIN CERTIFICATE-----\nMIID...\n-----END CERTIFICATE-----",
+  "server_crt": "-----BEGIN CERTIFICATE-----\nMIID...\n-----END CERTIFICATE-----",
+  "server_key": "-----BEGIN PRIVATE KEY-----\nMIGH...\n-----END PRIVATE KEY-----"
+}
+```
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `status` | string | Always `"approved"` for this variant |
+| `ca_crt` | string | PEM-encoded CA root certificate (for TLS verification) |
+| `server_crt` | string | PEM-encoded server certificate (manager's TLS leaf) |
+| `server_key` | string | PEM-encoded server private key (PKCS#8 format) |
+
+##### Denied
+
+```json
+{ "status": "denied" }
+```
+
+The administrator has rejected the enrollment request. The host should abort the enrollment process.
+
+##### Not Found (Token Expired or Invalid)
+
+```json
+{ "status": "not_found" }
+```
+
+The polling token does not match any pending or approved enrollment. This occurs when:
+- The token has expired (default TTL: 24 hours)
+- The token was never issued
+- The enrollment was already fulfilled and purged
+

+```
+
+**Step Details:**
+
+| Step | Action | Details |
+|------|--------|---------|
+| 1 | Host sends enrollment request | Extracts identity from `/etc/machine-id`, hostname, network interfaces, and OS release data |
+| 2 | Manager returns polling token | Token is 64-character random alphanumeric string; SHA256 hash stored in database |
+| 3 | Admin reviews pending requests | Manager exposes admin API for listing/approving/denying enrollment requests |
+| 4 | Host polls status periodically | Default interval: 60 seconds. Configurable via `--poll-interval` flag |
+| 5 | Host receives PKI bundle on approval | Complete CA chain, server certificate, and private key in PEM format |
+| 6 | Host provisions mTLS infrastructure | Writes certificates to configured paths, updates IP whitelist, transitions to authenticated mode |
+
+---
+
+### Rate Limiting
+
+| Endpoint | Limit | Window | Scope |
+|----------|-------|--------|-------|
+| `POST /api/v1/enroll` | 1 request | Per minute | Per source IP address |
+| `GET /api/v1/enroll/status/{token}` | No explicit limit | — | Host-controlled polling interval |
+
+**Rate Limit Enforcement:**
+- POST `/enroll`: Enforced by manager using in-memory LRU cache keyed on source IP (or `X-Forwarded-For` first entry when behind reverse proxy)
+- Status endpoint: No server-side rate limiting; client controls poll frequency (default: 60s interval)
+
+---
+
+### Security Notes
+
+| Concern | Mitigation |
+|---------|------------|
+| **Initial connection security** | TLS verification disabled on enrollment client (`danger_accept_invalid_certs`). Manager approval workflow provides authorization — transport encryption is secondary during pre-provisioning phase |
+| **Token secrecy** | Polling token is a 64-character random alphanumeric bearer credential. Never log the raw token value (only hash stored in DB). Tokens expire after 24 hours by default |
+| **Host identity** | `machine_id` from `/etc/machine-id` provides unique host identification. Combined with FQDN and IP for collision detection during admin approval |
+| **FQDN/IP collision** | Admin approval checks existing hosts table — rejects enrollment if FQDN or IP already registered to another host (HTTP 409 Conflict) |
+| **Certificate isolation** | Each approved host receives a unique client certificate signed by internal CA. Certificates have max 1-year validity |
+
+---
+
+### Error Reference Table
+
+| HTTP Status | Error Context | Description | Retryable |
+|-------------|---------------|-------------|----------|
+| `429` | POST /enroll | Rate limit exceeded (1/min per IP) | Yes — wait 60s |
+| `409` | Admin approve endpoint | FQDN or IP collision with existing host | No — resolve conflict first |
+| `500` | Any enrollment endpoint | Database error or internal server failure | Yes — transient |
+| `200` `{ "status": "denied" }` | GET /enroll/status/{token} | Administrator rejected request | No — contact administrator |
+| `200` `{ "status": "not_found" }` | GET /enroll/status/{token} | Token expired, invalid, or already consumed | No — re-enroll with new request |

+## Package Cache Management
+
+### Module: `src/packages/cache.rs`
+
+The package cache module manages the local package index state, ensuring that package metadata is current before performing operations.
+
+**Key Components:**
+- `PackageCacheState` - Thread-safe in-memory cache state with Mutex protection
+- `PackageCacheStatus` - Snapshot of cache state for reporting
+- `CacheStateFile` - Persistent state format for serialization
+- `is_fetch_error()` - Detects 404/fetch errors for automatic retry
+- `apply_with_cache_retry()` - Generic retry wrapper for cache-related failures
+- `run_command_with_timeout()` - Executes cache refresh commands with timeout
+
+**State Persistence:**
+- Cache state persists to `/var/lib/linux_patch_api/state/cache.json`
+- State is loaded on service startup and saved after every update
+- Persists `last_cache_update` timestamp and `last_update_success` flag
+- Parent directory is auto-created if missing
+
+**Stale Detection:**
+- Cache is considered stale after 4 hours (`STALE_THRESHOLD_SECS = 14400`)
+- Health check automatically refreshes stale cache
+- Patch apply operations always refresh cache before proceeding (mandatory)
+
+**Refresh-Before-Apply Flow:**
+1. `POST /patches/apply` creates a job and spawns background task
+2. Background task refreshes package cache (mandatory, not configurable)
+3. If refresh fails: job fails immediately with error message
+4. If refresh succeeds: job progresses to 10%, applies patches
+5. If apply fails with 404/fetch error: refresh cache and retry once
+6. If retry also fails: job fails with error
+
+**Cache Refresh Timeout:** 120 seconds (`CACHE_REFRESH_TIMEOUT_SECS`)

+## Building Arch Package (.pkg.tar.zst)
+
+### Quick Build
+
+```bash
+cd /path/to/linux_patch_api
+
+# Build release binary
+cargo build --release
+
+# Build Arch package
+chmod +x build-arch.sh
+SKIP_CARGO_BUILD=1 ./build-arch.sh
+
+# Package will be created in releases/
+ls -la releases/*.pkg.tar.zst
+```
+
+### Detailed Build Process
+
+```bash
+# 1. Install build dependencies (Arch Linux)
+sudo pacman -Syu --noconfirm rust cargo systemd git base-devel gcc
+
+# 2. Build release binary
+cargo build --release
+
+# 3. Run build script
+chmod +x build-arch.sh
+./build-arch.sh
+
+# 4. Verify package contents
+bsdtar -tf releases/linux-patch-api-*.pkg.tar.zst
+
+# 5. Verify package info
+pacman -Qi releases/linux-patch-api-*.pkg.tar.zst
+```
+
+### Install Script Hooks
+
+The Arch package includes an `.install` file (`configs/linux-patch-api.install`) that runs automatically on install:
+
+- **post_install**: Creates directories, copies example configs, enables systemd service
+- **post_upgrade**: Reloads systemd daemon
+- **pre_remove**: Stops and disables service
+- **post_remove**: Cleans up empty directories
+
+### Installation Test
+
+```bash
+# Install the package
+sudo pacman -U ./releases/linux-patch-api-*.pkg.tar.zst
+
+# Verify installation
+systemctl status linux-patch-api
+linux-patch-api --version
+
+# Check installed files
+pacman -Ql linux-patch-api
+
+# Verify config files exist
+ls -la /etc/linux_patch_api/
+
+# Remove package
+sudo pacman -R linux-patch-api
+```
+
+**Note:** The build script creates a `builduser` for `makepkg` when running as root (typical in CI environments). The `.install` hook handles directory creation, config copying, and service enablement.
+
+## Building Alpine Package (.apk)
+
+### Quick Build
+
+```bash
+cd /path/to/linux_patch_api
+
+# Build release binary (MUSL target for Alpine)
+cargo build --release --target x86_64-unknown-linux-musl
+
+# Build Alpine package
+chmod +x build-alpine.sh
+SKIP_CARGO_BUILD=1 ./build-alpine.sh
+
+# Package will be created in releases/
+ls -la releases/*.apk
+```
+
+### Detailed Build Process
+
+```bash
+# 1. Install build dependencies (Alpine Linux)
+apk add --no-cache alpine-sdk rust cargo openssl openssl-dev elogind-dev musl-dev abuild gcc
+
+# 2. Add Rust MUSL target
+rustup target add x86_64-unknown-linux-musl
+

+./build-alpine.sh
+
+# 5. Verify package contents
+apk verify releases/*.apk
+
+# 6. List package contents
+tar -tzf releases/*.apk
+```
+
+### Install Script Hooks
+
+The Alpine package includes an install script (`configs/linux-patch-api.apk-install`) that runs automatically on install:
+
+- **pre_install**: Creates directories, sets ownership and permissions
+- **post_install**: Copies example configs, adds service to default runlevel
+- **pre_deinstall**: Stops and removes service from runlevel
+- **post_deinstall**: Cleans up empty directories
+
+### Installation Test
+
+```bash
+# Install the package
+sudo apk add --allow-unstable ./releases/linux-patch-api-*.apk
+
+# Verify installation
+rc-service linux-patch-api status
+linux-patch-api --version
+
+# Check installed files
+apk info -L linux-patch-api
+
+# Verify config files exist
+ls -la /etc/linux_patch_api/
+
+# Remove package
+sudo apk del linux-patch-api
+```
+
+**Important:** Alpine uses **OpenRC** instead of systemd. Key differences:
+- Start service: `rc-service linux-patch-api start`
+- Stop service: `rc-service linux-patch-api stop`
+- Check status: `rc-service linux-patch-api status`
+- Service init script: `/etc/init.d/linux-patch-api`
+- The `abuild` tool generates signing keys automatically for CI builds

+## Self-Enrollment Deployment
+
+Self-enrollment allows a new host to automatically request and receive mTLS certificates from the `linux_patch_manager` without manual PKI distribution. The daemon supports two enrollment modes:
+
+1. **Auto-enrollment (recommended):** When `enrollment.manager_url` is configured in `config.yaml`, the daemon automatically enrolls on startup when certificates are missing or invalid. After provisioning, it continues to normal mTLS server startup.
+
+2. **Manual enrollment:** Run `linux-patch-api --enroll <manager_url>` explicitly. The process provisions certificates and **exits** — it does NOT start the server. Start the service separately after enrollment completes.
+
+### How It Works
+
+The enrollment workflow operates in three phases:
+
+1. **Registration:** Extracts `/etc/machine-id`, FQDN, IP address, and OS details. Submits an unauthenticated `POST /api/v1/enroll` request to the manager. Receives a temporary `polling_token`.
+2. **Polling & Approval:** Enters a polling loop querying `GET /api/v1/enroll/status/{token}` (default: every 60 seconds, up to 1440 attempts = 24 hours). Aborts on HTTP 403/404 (denied/purged). The polling token is persisted to `config.yaml` for resume after service restart.
+3. **Provisioning:** On HTTP 200, downloads the PKI bundle (`ca.crt`, `server.crt`, `server.key`), writes certificates to configured mTLS paths, appends manager IP to whitelist. For auto-enrollment, transitions to standard mTLS listening mode. For `--enroll`, exits with code 0.
+
+### Certificate Validation
+
+On startup, the daemon validates all configured TLS certificates before attempting to bind the listening port:
+
+1. **Existence:** All three cert files must exist at configured paths
+2. **Parse:** Each file must be valid PEM (X.509 for certs, PKCS#8/PKCS#1 for keys)
+3. **Expiry:** Certs must not be expired. Certs expiring within `cert_renewal_threshold_days` (default 7) trigger a warning
+4. **Key match:** Server cert public key must correspond to server key private key
+5. **CA trust:** Server cert must be signed by the CA cert
+
+Validation results determine startup behavior:
+
+| Result | Action |
+|--------|--------|
+| Valid | Start normally with mTLS |
+| ExpiringSoon | Log warning, start normally, schedule re-enrollment |
+| Missing/Corrupt/Expired/KeyMismatch/Untrusted | Auto-enroll if `enrollment.manager_url` configured, otherwise exit with guidance |
+
+### Prerequisites
+
+| Requirement | Details |
+|-------------|---------|
+| Manager URL | Must be accessible from the host (HTTPS) |
+| Network Connectivity | Outbound HTTPS to manager endpoint |
+| DNS Resolution | Manager hostname must resolve correctly |
+| systemd | Version 237+ for service management |
+| Root Access | Required for certificate file writes |
+
+**Verification before enrollment:**
+```bash
+# Verify network connectivity to manager
+curl -I https://manager.example.com
+
+# Verify DNS resolution
+nslookup manager.example.com
+
+# Verify outbound HTTPS works
+curl -ks https://manager.example.com/api/v1/health
+```
+
+### Deployment Method 1: Auto-Enrollment (Recommended)
+
+The simplest deployment. Just install the package, configure the manager URL, and start the service. The daemon handles the rest.
+
+#### Step 1: Install Package
+
+```bash
+# Debian/Ubuntu
+dpkg -i linux-patch-api_1.2.0-1_amd64.deb
+
+# RHEL/CentOS/Fedora
+rpm -ivh linux-patch-api-1.2.0-1.x86_64.rpm
+```
+
+#### Step 2: Configure Enrollment URL
+
+```bash
+# Edit the config to add manager URL
+cat >> /etc/linux_patch_api/config.yaml <<EOF
+
+enrollment:
+  manager_url: "https://linux-patch-manager-dev.moon-dragon.us"
+  polling_interval_seconds: 60
+  max_poll_attempts: 1440
+  cert_renewal_threshold_days: 7
+EOF
+```
+
+#### Step 3: Start Service
+
+```bash
+# Enable and start
+systemctl enable linux-patch-api
+systemctl start linux-patch-api
+
+# Watch auto-enrollment progress
+journalctl -u linux-patch-api -f
+```
+
+The daemon will:
+1. Validate certificates → find them missing
+2. Read `enrollment.manager_url` → begin auto-enrollment
+3. Register with manager, poll for approval
+4. Provision certificates after admin approval
+5. Continue to normal mTLS server startup
+
+**No manual `--enroll` command needed.** The service self-heals on restart if certificates are missing or invalid.
+
+#### Step 4: Admin Approval (Manager Side)
+
+On the `linux_patch_manager` dashboard:
+1. Navigate to Pending Enrollments
+2. Review host details (machine-id, FQDN, IP, OS)
+3. Approve the enrollment request
+4. Manager provisions PKI bundle and signals approval
+
+#### Step 5: Verify Successful Enrollment
+
+```bash
+# Check service is running
+systemctl status linux-patch-api
+
+# Verify certificates exist
+ls -la /etc/linux_patch_api/certs/
+
+# Test mTLS connection
+curl --cacert /etc/linux_patch_api/certs/ca.pem \
+     --cert /path/to/client.pem \
+     --key /path/to/client.key.pem \
+     https://localhost:12443/health
+```
+
+### Deployment Method 2: Manual Enrollment
+
+For environments where auto-enrollment is not desired, or for initial setup before the service is enabled.
+
+#### Step 1: Install Package
+
+```bash
+# Debian/Ubuntu
+dpkg -i linux-patch-api_1.2.0-1_amd64.deb
+
+# RHEL/CentOS/Fedora
+rpm -ivh linux-patch-api-1.2.0-1.x86_64.rpm
+```
+
+#### Step 2: Run Enrollment Command
+
+```bash
+# Basic enrollment with manager URL
+sudo linux-patch-api --enroll https://linux-patch-manager-dev.moon-dragon.us
+
+# With verbose logging for troubleshooting
+sudo linux-patch-api --enroll https://linux-patch-manager-dev.moon-dragon.us --verbose
+```
+
+**Important:** The `--enroll` command provisions certificates and **exits**. It does NOT start the server. This prevents port conflicts with the systemd service.
+
+The enrollment process will:
+- Extract machine identity from `/etc/machine-id` and system properties
+- Submit registration request to manager
+- Enter polling loop (logs progress every 60 seconds)
+- Await admin approval on the manager side
+- Download and install certificates automatically
+- Update IP whitelist with manager address
+- Print: "Enrollment complete. Start service: systemctl start linux-patch-api"
+- Exit with code 0
+
+#### Step 3: Start Service
+
+```bash
+systemctl enable linux-patch-api
+systemctl start linux-patch-api
+systemctl status linux-patch-api
+```
+
+### Certificate Renewal
+
+Certificates can be renewed manually or automatically:
+
+```bash
+# Manual renewal
+sudo linux-patch-api --renew-certs
+
+# Auto-renewal: certs expiring within cert_renewal_threshold_days trigger re-enrollment on startup
+```
+
+### Configuration Options
+
+Enrollment behavior can be tuned via the `enrollment` section in `/etc/linux_patch_api/config.yaml`:
+
+```yaml
+# Enrollment Configuration
+enrollment:
+  manager_url: "https://linux-patch-manager-dev.moon-dragon.us"
+  polling_interval_seconds: 60    # Time between approval polls (default: 60)
+  max_poll_attempts: 1440         # Maximum poll attempts (default: 1440 = 24 hours)
+  polling_token: ""               # Auto-populated during enrollment (do not edit)
+  cert_renewal_threshold_days: 7  # Days before expiry to trigger re-enrollment
+```
+
+**Parameter Reference:**
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `manager_url` | (none) | Manager URL for auto-enrollment. Required for auto-enrollment on startup. |
+| `polling_interval_seconds` | 60 | Seconds between approval status polls. Minimum: 10 |
+| `max_poll_attempts` | 1440 | Maximum polling attempts before timeout. Effective timeout = interval × attempts |
+| `polling_token` | (empty) | Auto-populated during enrollment for resume after restart. Do not edit manually. |
+| `cert_renewal_threshold_days` | 7 | Days before cert expiry to trigger automatic re-enrollment |
+
+**Effective Timeout Calculation:**
+- Default: 60s × 1440 = 86,400 seconds (24 hours)
+- Custom example: 30s × 720 = 21,600 seconds (6 hours)
+
+### Troubleshooting
+
+| Symptom | Cause | Resolution |
+|---------|-------|------------|
+| `Enrollment failed: connection refused` | Manager not reachable | Verify manager URL, check firewall rules |
+| `Enrollment failed: DNS resolution error` | Hostname cannot resolve | Check `/etc/resolv.conf`, verify DNS |
+| `HTTP 403 - Enrollment denied` | Admin rejected request | Contact manager admin to approve enrollment |
+| `HTTP 404 - Token not found` | Token expired/purged | Re-run enrollment command with `--enroll` flag |
+| `Polling timeout after N attempts` | Max attempts exceeded | Increase `max_poll_attempts` in config, re-enroll |
+| `Rate limited: 429 Too Many Requests` | Polling too frequently | Ensure `polling_interval_seconds >= 10` |
+| `Permission denied writing certificates` | Insufficient privileges | Run with `sudo` or as root user |
+| `Whitelist update failed` | File permission issue | Verify `/etc/linux_patch_api/` is writable by service user |
+
+**Diagnostic Commands:**
+```bash
+# Check enrollment logs
+journalctl -u linux-patch-api --since "1 hour ago"
+
+# Test manager connectivity
+curl -v https://manager.example.com/api/v1/enroll
+
+# Verify DNS resolution
+dig manager.example.com
+nslookup manager.example.com
+
+# Check certificate paths are writable
+ls -la /etc/linux_patch_api/certs/
+sudo touch /etc/linux_patch_api/certs/test && sudo rm /etc/linux_patch_api/certs/test
+```
+
+### Post-Enrollment Verification
+
+After successful enrollment, verify the following:
+
+1. **Certificate Files Exist:**
+   ```bash
+   ls -la /etc/linux_patch_api/certs/
+   # Expected: ca.pem (644), server.pem (644), server.key (600)
+   ```
+
+2. **Certificate Validity:**
+   ```bash
+   openssl x509 -in /etc/linux_patch_api/certs/server.pem -text -noout | grep -A2 "Validity"
+   openssl x509 -in /etc/linux_patch_api/certs/ca.pem -text -noout | grep -A2 "Validity"
+   ```
+
+3. **Whitelist Contains Manager IP:**
+   ```bash
+   cat /etc/linux_patch_api/whitelist.yaml
+   # Should contain manager IP address in entries list
+   ```
+
+4. **mTLS Connection Test:**
+   ```bash
+   curl --cacert /etc/linux_patch_api/certs/ca.pem \
+        --cert /path/to/client.pem \
+        --key /path/to/client.key.pem \
+        https://localhost:12443/health
+   # Expected: {"status": "ok"}
+   ```
+
+5. **Service Status:**
+   ```bash
+   systemctl status linux-patch-api
+   # Expected: active (running)
+   ```
+
+### Rollback and Re-Enrollment
+
+#### Removing Enrolled Certificates
+
+```bash
+# Stop the service
+sudo systemctl stop linux-patch-api
+
+# Remove provisioned certificates
+sudo rm -f /etc/linux_patch_api/certs/ca.pem
+sudo rm -f /etc/linux_patch_api/certs/server.pem
+sudo rm -f /etc/linux_patch_api/certs/server.key
+
+# Revert whitelist (remove manager IP entry)
+sudo vi /etc/linux_patch_api/whitelist.yaml
+```
+
+#### Re-Enrolling a Host
+
+```bash
+# Run enrollment again with same or different manager
+sudo linux-patch-api --enroll https://manager.example.com
+
+# Or enroll with a different manager
+sudo linux-patch-api --enroll https://new-manager.example.com
+```
+
+**Notes:**
+- Re-enrollment overwrites existing certificates in the configured paths
+- The previous polling token is discarded; a new registration request is submitted
+- If re-enrolling with the same manager, ensure the old enrollment was purged or approved
+
+### Enrollment vs Manual Certificate Deployment
+
+| Aspect | Self-Enrollment | Manual PKI |
+|--------|----------------|------------|
+| Certificate distribution | Automatic from manager | Manual SCP/copy |
+| Whitelist management | Auto-populated with manager IP | Manual configuration |
+| Admin approval required | Yes (on manager side) | N/A |
+| Network dependency | Requires outbound HTTPS to manager | None after cert distribution |
+| Best for | Large-scale deployments, automation | Air-gapped environments, single hosts |

+
+**Architecture Note:** The duplicate-header check was originally in `MtlsMiddleware`, which was dead code (never wired into the pipeline). It has been extracted into `SecurityHeadersMiddleware`, which IS wired into the pipeline and runs on every request. Client certificate authentication is handled at the TLS handshake level by rustls via `CrlAwareVerifier` — no application-layer certificate middleware is needed. See `src/auth/mtls.rs` for the ADR documenting this decision.
+

+
+## Architecture Decision Record: rustls as Authoritative Client-Auth Gate
+
+**Decision:** Client certificate authentication is enforced at the TLS handshake level by rustls via `CrlAwareVerifier`, NOT by application-layer middleware.
+
+**Context:** The original `MtlsMiddleware` was never wired into the Actix-web pipeline. It contained both a duplicate-header check (VULN-006) and a `validate_client_certificate()` stub that returned `Ok(())` unconditionally. Meanwhile, the actual client certificate verification was always performed by rustls at the TLS handshake level through `CrlAwareVerifier`, which wraps `WebPkiClientVerifier`.
+
+**Rationale:**
+- rustls provides battle-tested X.509 verification at the TLS handshake level
+- Enforcing auth at the TLS layer eliminates bypass vulnerabilities (middleware ordering bugs, route-specific skips)
+- CRL revocation checking is integrated into the same handshake path via `CrlAwareVerifier`
+- Application-layer certificate validation is redundant when the TLS layer already rejects untrusted connections
+
+**Consequences:**
+- `MtlsMiddleware` (Transform/Service) and `validate_client_certificate()` have been removed as dead code
+- `build_rustls_config()` is now a free function (no longer a method on `MtlsMiddleware`)
+- `SecurityHeadersMiddleware` handles VULN-006 (duplicate critical header rejection) as a dedicated, wired middleware
+- `ClientCertInfo` struct is preserved for potential future use in extracting certificate details from TLS sessions

+## Usage Examples
+
+### Standard Startup (Existing Certificates)
+
+When certificates are already provisioned, start with the configuration path:
+
+```bash
+sudo linux-patch-api --config /etc/linux_patch_api/config.yaml
+```
+
+Or via systemd (recommended for production):
+
+```bash
+systemctl enable linux-patch-api
+systemctl start linux-patch-api
+```
+
+### Self-Enrollment with Manager
+
+Bootstrap a new host by automatically requesting certificates from the manager:
+
+```bash
+sudo linux-patch-api --enroll https://manager.example.com
+```
+
+The enrollment workflow:
+1. Extracts machine identity (`/etc/machine-id`, FQDN, OS details)
+2. Registers with manager (`POST /api/v1/enroll`)
+3. Polls for admin approval (default: every 60 seconds, up to 24 hours)
+4. Downloads PKI bundle on approval
+5. Writes certificates and updates whitelist automatically
+6. Starts mTLS server without requiring a restart
+
+```bash
+# Enrollment with verbose logging
+sudo linux-patch-api --enroll https://manager.example.com --verbose
+```
+
+For detailed enrollment procedures, see [DEPLOYMENT_GUIDE.md - Self-Enrollment Deployment](./DEPLOYMENT_GUIDE.md#self-enrollment-deployment).

+- Stop service: `rc-service linux-patch-api stop`
+- Check status: `rc-service linux-patch-api status`
+- The service is added to the `default` runlevel automatically on install
+- Service init script: `/etc/init.d/linux-patch-api`
+
 ### Manual Installation
 
 For systems without package manager support:
 
 ```bash
 # Run interactive installer (requires root)
-./install.sh
+sudo ./install.sh
 ```
 
 The installer will:
 - Detect operating system
-- Create system user and group
+- Create directory structure (`/etc/linux_patch_api/`, `/var/lib/linux_patch_api/`, `/var/log/linux_patch_api/`)
-- Set up directory structure
+- Install binary to `/usr/bin/linux-patch-api`
-- Install binary and configuration files
+- Install example configs
 - Configure systemd service
+- Set correct permissions
 
 ### Building from Source
 
+#### Prerequisites (all platforms)
+
+- Rust toolchain (stable channel, 1.75+)
+- OpenSSL development headers
+- systemd development headers
+- C compiler (gcc)
+
+#### Build Debian Package (.deb)
+
 ```bash
-# Clone repository
+# On Debian/Ubuntu
-git clone https://gitea.internal/linux-patch-api.git
+apt-get install -y build-essential debhelper pkg-config libsystemd-dev libssl-dev cargo rustc
-cd linux-patch-api
+cargo build --release
-
+sudo dpkg-buildpackage -us -uc -b
-# Build release binary
-cargo build --release --target x86_64-unknown-linux-gnu
-
-# Build Debian package
-dpkg-buildpackage -us -uc -b
-
-# Or build RPM package
-rpmbuild -ba linux-patch-api.spec
 ```
 
+#### Build RPM Package (.rpm)
+
+```bash
+# On Fedora/RHEL/CentOS
+dnf install -y rpm-build cargo rust gcc openssl-devel systemd-devel pkgconfig
+cargo build --release --target x86_64-unknown-linux-gnu
+chmod +x build-rpm.sh
+./build-rpm.sh
+```
+
+**Note:** The RPM spec includes `BuildRequires` for native RPM build environments. When building in CI containers (where deps are pre-installed via apt-get), these are informational only.
+
+#### Build Arch Package (.pkg.tar.zst)
+
+```bash
+# On Arch Linux/Manjaro
+pacman -Syu --noconfirm rust cargo systemd git base-devel gcc
+cargo build --release
+chmod +x build-arch.sh
+SKIP_CARGO_BUILD=1 ./build-arch.sh
+```
+
+**Note:** The build script creates a `builduser` for `makepkg` when running as root (typical in CI). The `.install` hook handles directory creation, config copying, and service enablement.
+
+#### Build Alpine Package (.apk)
+
+```bash
+# On Alpine Linux 3.18+
+apk add --no-cache alpine-sdk rust cargo openssl openssl-dev elogind-dev musl-dev abuild gcc
+cargo build --release --target x86_64-unknown-linux-musl
+chmod +x build-alpine.sh
+SKIP_CARGO_BUILD=1 ./build-alpine.sh
+```
+
+**Important:** Alpine requires the `x86_64-unknown-linux-musl` target for static linking. The build script handles `abuild` key generation and runs as a `builduser` when executed as root.
+
 See [BUILD_PACKAGES.md](./BUILD_PACKAGES.md) for detailed build instructions.

+## Reporting a Vulnerability
 
-## Threat Model
+**Do not report security vulnerabilities through public GitHub Issues.**
 
-### Threat Actor Profile
+Instead, use GitHub's private vulnerability reporting:
 
-| Attribute | Description |
+👉 [Report a vulnerability for Linux-Patch-Api](https://github.com/Draco-Lunaris/Linux-Patch-Api/security/advisories/new)
-|-----------|-------------|
-| **Origin** | Internal network only |
-| **Skill Level** | Moderate to High |
-| **Resources** | Limited (not nation-state) |
-| **Motivation** | Unauthorized system access, privilege escalation |

----
+We follow **coordinated disclosure**:
 
-## Authentication & Authorization
+- We ask for **90 days** before public disclosure of a vulnerability
+- Security advisories are published via [GitHub Security Advisories](https://github.com/Draco-Lunaris/Linux-Patch-Api/security/advisories)
+- We will work with you to determine an appropriate disclosure timeline when a fix requires more time
 
-### Authentication Requirements
+## Security Best Practices
 
-- **Method:** mTLS certificate-based authentication
+This project is a security tool — we hold ourselves to a high standard:
-- **Certificate Type:** Unique client certificate per client (1-year validity)
-- **CA:** Internal self-hosted Certificate Authority
-- **TLS Version:** TLS 1.3 only
-- **Multi-factor:** Certificate + IP whitelist (dual requirement)
-- **Session Management:** Stateless (no sessions)
 
-### Authorization Model
+- **Signed commits**: All commits must be signed (SSH signing)
+- **CI enforcement**: All PRs require passing CI checks (fmt, clippy, test, audit, build)
+- **Dependency auditing**: `cargo audit` runs in CI to catch known vulnerabilities
 
-- **Model:** Binary authorization (all-or-nothing)
+## Credit
-- **Permission Levels:** Single level (full access if authenticated)
-- **Requirements:**
-  - Valid mTLS certificate (not expired, signed by internal CA)
-  - Source IP in whitelist (YAML config, instant apply)
-- **No RBAC:** All authenticated clients have full API access
 
----
+Contributors who responsibly report vulnerabilities will be credited in the corresponding GitHub Security Advisory.

-## Data Security
-
-### Encryption at Rest
-
-- **Certificates:** File permissions 600 for private keys
-- **Job Storage:** `/var/lib/linux_patch_api/jobs/` (cleared on restart)
-- **Config Files:** `/etc/linux_patch_api/` (644 for config, 600 for keys)
-- **Audit Logs:** systemd journal (immutable by default)
-
-### Encryption in Transit
-
-- **Protocol:** TLS 1.3 only
-- **Port:** 12443
-- **Cipher Suites:** TLS 1.3 default (no legacy cipher support)
-- **Certificate Validation:** Mutual TLS (server + client cert required)
-
-### Key Management
-
-- **CA Private Key:** Stored securely on CA host only
-- **Server Certificates:** `/etc/linux_patch_api/certs/server.key` (600)
-- **Client Certificates:** Distributed manually to authorized clients
-- **Rotation:** 1-year certificate expiry, manual renewal process
-- **Revocation:** Not implemented (rely on expiry + physical cert retrieval)
-
----
-
-## API Security
-
-### Input Validation
-
-- **Package Names:** Alphanumeric + standard package chars only
-- **Versions:** Semantic versioning validation
-- **IP Addresses:** IPv4 + CIDR validation for whitelist
-- **JSON Schema:** Strict schema validation for all request bodies
-- **Path Traversal:** Blocked (no `..` in paths)
-
-### Rate Limiting
-
-- **Not Required:** Internal network only with strict IP whitelist
-- **Job Concurrency:** Configurable limit (default: 5 concurrent jobs)
-- **Job Timeout:** 30-minute maximum per job
-
-### CORS Policy
-
-- **Not Applicable:** API is not browser-accessible
-- **Origin:** mTLS clients only (no browser CORS concerns)
-
----
-
-## Audit & Logging
-
-### Security Events to Log
-
-- All API requests (endpoint, method, timestamp, client cert ID, source IP)
-- Authentication events (success/failure, cert validation result)
-- Authorization events (IP whitelist match/failure)
-- Package operations (package name, version, action, result)
-- Configuration changes (config reload, whitelist updates)
-- Job lifecycle events (create, start, complete, fail, timeout, rollback)
-- Service events (start, stop, restart, config validation failures)
-
-### Log Protection
-
-- **Primary Storage:** systemd journal (immutable, access-controlled)
-- **Secondary Storage:** Optional remote syslog
-- **Fallback:** Local file `/var/log/linux_patch_api/audit.log` (640)
-- **Retention:** 30 days with daily rotation and compression
-- **Access:** Root only, audit group read access
-- **Integrity:** systemd journal provides tamper evidence
-
----
-
-## Compliance Requirements
-
-- **Internal Standards:** Follows organizational security policies
-- **No External Compliance:** Not designed for PCI-DSS, HIPAA, SOC2 (can be extended)
-- **Audit Trail:** Comprehensive logging supports internal audit requirements
-- **Access Control:** mTLS + IP whitelist provides strong access control
-
----
-
-## Security Testing
-
-### Penetration Testing
-
-- **Schedule:** Required before production deployment
-- **Scope:**
-  - mTLS authentication bypass attempts
-  - IP whitelist enforcement testing
-  - API endpoint fuzzing
-  - Certificate validation testing
-  - Config file tampering attempts
-  - Privilege escalation attempts
-- **Tester:** Internal security team or external contractor
-- **Frequency:** Annual or after major changes
-
-### Vulnerability Management
-
-- **Dependency Scanning:** Rust crate security advisories monitored
-- **System Patches:** Host system patched via API itself (dogfooding)
-- **Certificate Updates:** Annual renewal process
-- **Config Audits:** Quarterly review of whitelist and security settings
-- **Incident Response:** Log analysis for security event investigation

+### 🔴 CRITICAL: Committed Private Key Material (Issue #12)
+
+**Description:**  
+Private key files (`*.key`, `*.key.pem`) were committed to version control in:
+- `configs/certs/ca.key.pem` — CA private key
+- `configs/certs/server.key.pem` — Server private key
+- `configs/certs/client001.key.pem` — Client private key
+- `tests/e2e/certs/client.key` — E2E test client private key
+
+Committed private keys are a critical security risk: anyone with repository access
+(even read-only) can impersonate the server or clients, decrypt captured TLS traffic,
+or forge certificates signed by the CA.
+
+**Status:** ✅ RESOLVED
+
+**Remediation Applied:**
+1. Removed all private key files from git tracking (`git rm --cached`)
+2. Added `*.key`, `*.key.pem`, `configs/certs/`, and `tests/e2e/certs/*.key` to `.gitignore`
+3. Created `scripts/generate-dev-certs.sh` to generate test certificates at runtime
+4. Updated e2e tests to generate certificates on demand instead of loading from disk
+5. Added `gitleaks` secret scanning to CI pipeline
+6. Git history will be purged with `git filter-repo` after PR merge
+
+**Key Rotation:**  
+These keys were used for development/testing only. No production key rotation is needed.
+All committed keys should be considered compromised and must not be used in any
+production environment.

+**Context:** Issue #13
+
+### Decision
+
+Client certificate authentication is enforced at the TLS handshake level by rustls via `CrlAwareVerifier`, NOT by application-layer middleware.
+
+### Context
+
+The original `MtlsMiddleware` was never wired into the Actix-web pipeline (dead code). It contained:
+1. A duplicate-header check (VULN-006) that never ran
+2. A `validate_client_certificate()` stub that returned `Ok(())` unconditionally
+
+Meanwhile, actual client certificate verification was always performed by rustls at the TLS handshake level through `CrlAwareVerifier` (which wraps `WebPkiClientVerifier`), with CRL revocation checking integrated into the same path.
+
+### Changes Made
+
+1. **Removed dead code:** `MtlsMiddleware`, `MtlsMiddlewareService`, `validate_client_certificate()`, and the Transform/Service impls
+2. **Extracted VULN-006:** `has_duplicate_critical_headers()` moved to new `SecurityHeadersMiddleware` (wired into pipeline)
+3. **Converted `build_rustls_config()`** from method on `MtlsMiddleware` to free function
+4. **Preserved:** `CrlAwareVerifier`, `MtlsConfig`, `MtlsError`, `ClientCertInfo`, `build_rustls_config()`, and all CRL infrastructure
+
+### Rationale
+
+- rustls provides battle-tested X.509 verification at the TLS handshake level
+- Enforcing auth at the TLS layer eliminates bypass vulnerabilities (middleware ordering bugs, route-specific skips)
+- CRL revocation checking is integrated into the same handshake path
+- Application-layer certificate validation is redundant when TLS already rejects untrusted connections

 ## Certificate Management
 
 - **CA Type:** Internal self-hosted Certificate Authority
-- **Distribution:** Manual certificate distribution to clients
+- **Distribution:** Automated Self-Enrollment (preferred) OR manual certificate distribution
+  - Auto-Enrollment: daemon automatically enrolls on startup when certs are missing/invalid and `enrollment.manager_url` is configured
+  - Manual Enrollment: `linux-patch-api --enroll <url>` for explicit enrollment (exits after completion, does not start server)
+  - Eliminates manual certificate copy/permission management for new hosts
 - **Scope:** Limited distribution (small number of authorized clients)
 - **Validity Period:** 1 year standard expiration
 - **Client Identity:** Unique certificate per client (no shared certs)
-- **Rotation:** Manual renewal process before expiration
+- **Rotation:** Automatic re-enrollment when certs are expiring within threshold, or manual via `--renew-certs`
+
+## Certificate Validation
+
+On startup, the daemon validates all configured TLS certificates before attempting to bind the listening port. Validation checks (in order):
+
+1. **Existence**: All three cert files (`ca_cert`, `server_cert`, `server_key`) must exist at configured paths
+2. **Parse**: Each file must be valid PEM — CA and server cert must parse as X.509, server key must parse as PKCS#8 or PKCS#1
+3. **Expiry**: CA cert and server cert must not be expired (`not_after > now`). Certs expiring within `cert_renewal_threshold_days` (default 7) trigger a warning and auto-re-enrollment
+4. **Key match**: Server cert's public key must correspond to server key's private key
+5. **CA trust**: Server cert must be signed by the CA cert (or chain validates to CA)
+
+Validation results determine startup behavior:
+
+| Result | Action |
+|--------|--------|
+| Valid | Start normally with mTLS |
+| ExpiringSoon | Log warning, start normally, schedule background re-enrollment |
+| Missing/Corrupt/Expired/KeyMismatch/Untrusted | Trigger auto-enrollment if `enrollment.manager_url` configured, otherwise exit with guidance |
+
+## Self-Enrollment Workflow
+
+The `linux_patch_api` daemon supports automated self-enrollment to securely request identity from the `linux_patch_manager` without manual PKI distribution. Enrollment can be triggered automatically on startup or manually via CLI.
+
+### Auto-Enrollment on Startup
+
+When cert validation fails AND `enrollment.manager_url` is configured in config.yaml, the daemon automatically enters enrollment mode:
+
+1. Log: "Certs [status]. Auto-enrolling with <url>"
+2. Skip cert validation (`skip_tls_validation=true`)
+3. Register with manager (POST /api/v1/enroll)
+   - If host already exists: log warning, skip to step 5 (polling for re-provisioning)
+   - If new registration: receive polling token
+4. Poll for approval (GET /api/v1/enroll/status/{token})
+   - Persist `polling_token` to config.yaml for resume after restart
+   - Retry with exponential backoff on network errors
+5. When approved: provision certs (ca.pem, server.pem, server.key)
+6. Re-validate certs (should now be Valid)
+7. Continue to normal mTLS server startup
+
+If enrollment fails (network error, manager unreachable):
+- Log: "Auto-enrollment failed: [error]. Retrying on next restart."
+- Exit code 1 (triggers systemd restart with backoff)
+
+If no enrollment URL is configured and certs are invalid:
+- Log clear error with guidance (add URL, run --enroll, or place certs manually)
+- Exit code 0 (don't trigger restart loop)
+
+### Polling Token Resume
+
+If the service restarts during enrollment polling:
+1. Read `polling_token` from config.yaml (persisted during enrollment)
+2. If token exists and `enrollment.manager_url` is configured:
+   a. Resume polling from where left off
+   b. Don't re-register (host already has a pending request)
+3. On successful provisioning:
+   a. Clear `polling_token` from config.yaml
+   b. Continue to normal server startup
+
+### CLI Enrollment (`--enroll`)
+
+```
+linux-patch-api --enroll https://<manager_url>
+```
+
+The enrollment flow runs and **exits after completion** — it does NOT start the server. This prevents port conflicts with the systemd service.
+
+- On success: prints "Enrollment complete. Start service: systemctl start linux-patch-api" and exits with code 0
+- On failure: exits with code 1 (triggers systemd restart if configured)
+
+### Security Model
+- Initial connection uses TLS with verification disabled (`danger_accept_invalid_certs`)
+- Manager approval workflow provides authorization; transport encryption is secondary during enrollment
+- URL scheme validation prevents SSRF/path traversal (only `http` and `https` permitted)
+- Host component required in manager URL
+
+### Phase 1: Registration Request
+- **Identity Extraction:**
+  - `/etc/machine-id` (fallback: `/var/lib/dbus/machine-id`)
+  - FQDN from `hostname -f` (validated contains `.`) → `hostname` + `hostname -d` → `/etc/hostname` → `hostname` → `localhost`
+  - Non-loopback IPv4 addresses via network interface enumeration
+  - OS details from `/etc/os-release` (distro, version, id_like, codename) + kernel version (`uname -r`)
+- **Submission:** Unauthenticated `POST /api/v1/enroll` to manager with identity payload
+- **Response:** HTTP 202 with temporary `polling_token` (bearer credential — never logged)
+- **Rate Limiting:** Manager enforces 1 request/minute per IP (HTTP 429 on violation)
+
+### Phase 2: Polling & Approval
+- **Polling Loop:** `GET /api/v1/enroll/status/{token}` with configurable interval and max attempts
+- **Default Interval:** 60 seconds (configurable via `enrollment.polling_interval_seconds`)
+- **Hard Timeout:** 24 hours maximum (1440 attempts; values >1440 clamped to 1440)
+- **Status States:**
+  - `pending`: Continue polling
+  - `approved`: Proceed to Phase 3 with PKI bundle
+  - `denied`: Abort enrollment (`ENROLLMENT_DENIED`)
+  - `not_found`: Token expired/purged — abort (`ENROLLMENT_EXPIRED`)
+- **Signal Handling:** SIGINT (Ctrl+C) and SIGTERM interrupt polling gracefully
+- **Transient Errors:** Network failures and HTTP 5xx retried with backoff; HTTP 404/429 terminate immediately
+- **Log Throttling:** Status logged every 10 attempts or after 5 minutes elapsed
+
+### Phase 3: PKI Provisioning
+- **Certificate Validation:** PEM format verification for CA cert, server cert, and server key (supports PKCS#8, PKCS#1 RSA, EC keys)
+- **Atomic Writes:** Temp file → set permissions → atomic rename pattern prevents partial writes
+- **File Permissions:** Keys at `0600`, certificates at `0644`, directories at `0755`
+- **Backup Strategy:** Existing certificate files renamed to `.bak` before overwrite
+- **Target Paths:** Configured via TLS settings or defaults (`/etc/linux_patch_api/certs/{ca,server,server.key}.pem`)
+- **Whitelist Auto-Append:** Manager IP resolved (hostname → DNS or direct IP) and appended to `/etc/linux_patch_api/whitelist.yaml`
+- **Completion:** For auto-enrollment: daemon transitions to standard mTLS listening mode without requiring service restart. For `--enroll`: daemon exits with code 0.

+| `--config <PATH>` or `-c` | Path to configuration file (default: `/etc/linux_patch_api/config.yaml`) |
+| `--verbose` or `-v` | Enable verbose (DEBUG-level) logging |
+| `--enroll <MANAGER_URL>` | Run self-enrollment flow with manager at URL, then EXIT (does not start server) |

+| `--help` or `-h` | Display help information and exit |
+
+### Enrollment Mode Behavior
+
+- **`--enroll <URL>`**: Executes enrollment flow, provisions certs, then **exits with code 0**. Does NOT start server or bind port. Print guidance message on completion.
+- **Auto-enrollment (startup)**: Triggered when cert validation fails and `enrollment.manager_url` is configured. After provisioning, continues to normal server startup.
+- **`--renew-certs`**: Validates existing certs. If expiring within threshold or invalid, re-enrolls using `enrollment.manager_url` from config. Exits with code 0 after completion.
+- TLS verification is disabled on initial manager connection (manager approval workflow provides security)
+
+### Exit Codes

+| Code | Meaning | systemd Behavior |
+|------|---------|------------------|
+| 0 | Clean exit: no certs and no enrollment URL configured, or --enroll/--renew-certs success | No restart |

+# Development Certificates
+
+**⚠️ Private keys are NOT committed to version control.**
+
+This directory is used for local development certificates only. Private key
+files (`*.key`, `*.key.pem`) are excluded from git via `.gitignore`.
+
+## Generating Development Certificates
+
+Run the generation script from the repository root:
+
+```bash
+./scripts/generate-dev-certs.sh
+```
+
+This creates:
+- `ca.pem` / `ca.key.pem` — Internal CA certificate and key
+- `server.pem` / `server.key.pem` — Server certificate and key
+- `client001.pem` / `client001.key.pem` — Client certificate and key
+- `tests/e2e/certs/` — E2E test certificates
+
+## Production Deployments
+
+Production deployments should use certificates issued by the organisation's
+internal CA. The `install.sh` script and systemd unit handle production
+certificate paths at `/etc/linux_patch_api/certs/`.
+
+## Security
+
+- **Never commit private keys** (`*.key`, `*.key.pem`) to version control
+- Private keys must have `0600` permissions in production
+- The `gitleaks` CI check scans for accidentally committed secrets
+- See `SECURITY_FINDINGS_REPORT.md` and `SECURITY.md` for full details

+
+* Tue May 20 2026 Echo <echo@moon-dragon.us> - 1.1.15-1
+- Add DNF package manager backend for Fedora/RHEL/CentOS 8+
+- Add YUM package manager backend for RHEL/CentOS 7
+- Fix: DNF backend not yet implemented error on Fedora systems
+- Support rpm -qa for package listing, rpm -qi for package details
+- Support dnf check-update (exit code 100) for patch detection
+- Support yum check-update (exit code 100) for patch detection
+
+* Tue May 20 2026 Echo <echo@moon-dragon.us> - 1.1.14-1
+- Fix RPM packaging: pre-build binary before tarball (like Alpine/Arch pattern)
+- Fix rpmbuild can't find cargo in PATH - binary now included in source tarball
+- Fix config file ownership: add %defattr(-,root,root,-) in %files section
+- Fix Requires: libsystemd -> systemd-libs for Fedora compatibility
+- Remove Requires: systemd (not needed, may not exist in containers)
+- Add stale RPM cleanup and version verification to build-rpm.sh
