feat: add version display to sidebar and bump to v1.1.4

Three issues fixed in the multi-stage Docker build:

1. CRITICAL: Add COPY migrations/ to rust-builder stage
   - sqlx::migrate!(../../migrations) is a compile-time proc macro
   - Without migrations/ present, cargo build fails with 'no such file or directory'
   - Previously migrations/ was only copied in runtime stage (too late)

2. Copy individual crate Cargo.toml files for dependency caching
   - The dummy-build caching step only copied workspace Cargo.toml/Cargo.lock
   - Without crate-level manifests, cargo couldn't resolve the workspace
   - This meant the cache layer was ineffective (rebuilt everything on code changes)

3. Add openssl package to runtime stage
   - entrypoint.sh uses openssl rand, openssl genpkey, openssl pkey
   - Only libssl3t64 (shared library) was installed, not the CLI tool
   - Runtime would fail on first-run key generation

All stages verified: Ubuntu 24.04 ✅  Rust via rustup (1.85+) ✅

+## Reporting a Vulnerability
+
+**Do not report security vulnerabilities through public GitHub Issues.**
+
+Instead, use GitHub's private vulnerability reporting:
+
+👉 [Report a vulnerability for Linux-Patch-Manager](https://github.com/Draco-Lunaris/Linux-Patch-Manager/security/advisories/new)
+
+This allows us to coordinate a fix before public disclosure.
+
+### Response Timeline
+
+- **Acknowledgment** within 48 hours
+- **Initial assessment** within 7 days
+- **Ongoing updates** on remediation progress
+
+## Disclosure Policy
+
+We follow **coordinated disclosure**:
+
+- 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-Manager/security/advisories)
+- We will work with you to determine an appropriate disclosure timeline when a fix requires more time
+
+## Security Best Practices
+
+This project is a security tool — we hold ourselves to a high standard:
+
+- **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
+
+## Enrollment PKI Design Decisions
+
+### Server-Generated Keys vs CSR-Based Enrollment
+
+Currently, the server generates the agent's private key during enrollment approval and
+transmits it over the mTLS-secured polling endpoint. This approach was chosen for
+initial implementation simplicity — the agent polls a single endpoint and receives a
+complete PKI bundle without an extra round-trip.
+
+**Mitigations in place:**
+- The PKI bundle is stored in an in-memory cache with single-retrieval semantics —
+  it can only be fetched once and is atomically removed on retrieval.
+- A 10-minute TTL ensures the bundle expires even if never retrieved.
+- The raw polling token is never logged; only its SHA-256 hash is stored.
+
+**Future direction:** A CSR-based enrollment flow should replace server-generated keys.
+Under that model, the agent generates its own key pair locally and submits a Certificate
+Signing Request, eliminating the need for the server to ever hold or transmit the agent's
+private key. This significantly reduces the attack surface.
+
+See: [Issue #9](https://github.com/Draco-Lunaris/Linux-Patch-Manager/issues/9)

+## Appendix: App-Level Secret Encryption (Issue #6, May 2026)
+
+In addition to the hardware-level full-disk encryption described above, issue #6 (PR [TBD]) added **application-level AES-256-GCM encryption** for three specific sensitive fields that DB exfiltration would otherwise expose:
+
+| Field | Table | Encryption key |
+|-------|-------|----------------|
+| `client_secret` | `oidc_config` | `/etc/patch-manager/keys/secret-encryption.key` |
+| `smtp_password` | `system_config` (key-value row) | same key |
+| `totp_secret` | `users` | same key |
+
+**Why app-level on top of hardware-level?** Hardware-level encryption protects against disk theft; app-level encryption protects against DB exfiltration (SQL injection, backup theft, insider threat) where the attacker already has the running process's privileges. The two are complementary.
+
+**Blast-radius isolation:** A separate per-install key is used for app secrets (`secret-encryption.key`), distinct from the health-check key (`health-check.key`). If the health-check key is ever compromised, app secrets remain protected.
+
+**API surface:** No change. The `MASKED` placeholder behavior in API responses is preserved on top of the new DB encryption — defense in depth.
+
+**Backup:** Both key files must be included in `/etc/patch-manager` backups. Without the key file, encrypted data is unrecoverable. See [docs/runbooks/key-management.md](docs/runbooks/key-management.md) for the full procedure.
+
+**Key rotation:** Not yet supported (follow-up issue). If a key is compromised, generate a new key and re-provision affected secrets.

+//! secret-encryption key, and writes to the new BYTEA columns. Verifies the
+//! round-trip (encrypt -> decrypt = original plaintext) before committing.
+//!
+//! USAGE:
+//!   export DATABASE_URL="postgres://patch_manager:<password>@localhost/patch_manager"
+//!   cargo run -p migrate-secrets
+//!
+//! This tool is safe to run multiple times (idempotent — re-encrypts and overwrites).
+//!
+//! See `tasks/secret-encryption-spec.md` section 4.5 for the design.

+# Agent Client Certificates
+
+**⚠️ Private keys are NOT committed to version control.**
+
+This directory holds mTLS certificates used by `pm-agent-client` for testing.
+The entire directory is excluded from git via `.gitignore`.
+
+## Generating Test Certificates
+
+Certificates are generated automatically on first run by the `pm-ca` service,
+or you can generate them manually for development:
+
+```bash
+# Create certs directory if it doesn't exist
+mkdir -p crates/pm-agent-client/certs
+
+# Generate using the pm-ca service (preferred)
+# Or copy from /etc/patch-manager/certs/ on a deployed host
+```
+
+## Production Deployment
+
+Production certificates are managed by `pm-ca` at `/etc/patch-manager/certs/`.
+The `pm-agent-client` reads certificates from file paths configured in
+`config.toml` (`agent_client_cert_path`, `agent_client_key_path`, `ca_cert_path`).
+
+## Security
+
+- **Never commit private keys** (`*.key`, `*.key.pem`) to version control
+- The `gitleaks` CI check scans for accidentally committed secrets
+- See `SECURITY.md` and `docs/security-review.md` for full details

+| `crl_invalid` | CRL status becomes `invalid` | `host_id`, `old_crl_status`, `new_crl_status`, `crl_age_seconds` |
+
+All CRL audit events use `target_type = "host"` and `target_id = <host_id>`. Actor fields (`actor_user_id`, `actor_username`) are `null` because these are system-initiated events.
+
+### CRL Health Aggregation Rules
+
+The health poller applies the following rules to determine a host's effective health status based on CRL state:
+
+| CRL Status | Condition | Effective Health Status |
+|---|---|---|
+| `invalid` | Always | `unreachable` (security event) |
+| `expired` | If natural status is `healthy` | `degraded` |
+| `missing` | Registered > 24h ago AND natural status is `healthy` | `degraded` |
+| `missing` | Registered ≤ 24h ago | Natural status (new agent enrollment) |
+| `valid` | Any | Natural status (no override) |
+| `null` | Any | Natural status (older agent, not reporting CRL) |
+
+When CRL status transitions from `invalid`/`expired`/`missing` back to `valid`, the next health poll cycle restores the host to its natural health status based on the agent's health response.

+# Key Management Runbook
+
+**Applies to:** Linux Patch Manager production deployments (issue #6 — secret encryption at rest)
+**Last updated:** 2026-06-03
+**Owner:** SRE / Security
+
+---
+
+## Overview
+
+Linux Patch Manager uses two per-install AES-256-GCM encryption keys for protecting sensitive data at rest. Both keys are auto-generated on first start of the service, stored as 32-byte files with `0600` permissions (owner read/write only).
+
+| Key file | Path | Protects | Used by |
+|----------|------|----------|---------|
+| `health-check.key` | `/etc/patch-manager/keys/health-check.key` | HTTP basic-auth passwords for health check endpoints | `pm-web`, `pm-worker` |
+| `secret-encryption.key` | `/etc/patch-manager/keys/secret-encryption.key` | OIDC `client_secret`, SMTP `smtp_password`, TOTP `totp_secret` | `pm-web`, `pm-auth`, `pm-worker` |
+
+The two keys are separate by design (blast-radius isolation): if the health-check key is ever compromised, the app secrets remain protected by a different key.
+
+---
+
+## Key Generation (First Start)
+
+On first start of `pm-web` or `pm-worker`, the `crypto::load_or_create_key()` function checks for each key file. If missing, it:
+
+1. Creates the `/etc/patch-manager/keys/` directory (mode `0700`)
+2. Generates 32 cryptographically random bytes via `OsRng` (the OS CSPRNG)
+3. Writes the key to disk
+4. Sets permissions to `0600` (owner read/write only)
+5. Returns the key to the calling code
+
+The key files are created in the order they are first accessed. If `pm-worker` starts before `pm-web`, it creates the same key file (filesystem-shared). Both processes can read the same key.
+
+---
+
+## Backup
+
+**Both key files MUST be included in `/etc/patch-manager` backups.** Without the key files, encrypted data is unrecoverable. Recommended backup procedure:
+
+```bash
+# Include the keys directory in the backup archive
+tar -czf /backup/patch-manager-$(date +%F).tar.gz \
+    /etc/patch-manager/config.toml \
+    /etc/patch-manager/keys/ \
+    /var/lib/patch-manager/  # if used
+
+# Verify the keys are in the backup
+tar -tzf /backup/patch-manager-*.tar.gz | grep -E 'keys/.*\.key$'
+```
+
+The existing `scripts/backup.sh` already excludes secrets from unencrypted backups and supports GPG encryption for the archive. Ensure the backup includes the keys directory.
+
+---
+
+## Verification (Production)
+
+To verify both keys exist and have correct permissions on a running deployment:
+
+```bash
+# Check both key files exist with 0600 permissions
+for key in health-check.key secret-encryption.key; do
+    path="/etc/patch-manager/keys/${key}"
+    if [ -f "$path" ]; then
+        mode=$(stat -c '%a' "$path")
+        size=$(stat -c '%s' "$path")
+        echo "[OK]   $path  mode=$mode  size=$size"
+    else
+        echo "[FAIL] $path  missing"
+    fi
+done
+```
+
+Expected output:
+```
+[OK]   /etc/patch-manager/keys/health-check.key  mode=600  size=32
+[OK]   /etc/patch-manager/keys/secret-encryption.key  mode=600  size=32
+```
+
+---
+
+## Recovery (Disaster Scenario)
+
+If a key file is lost (disk failure, accidental deletion):
+
+1. **All encrypted data becomes unrecoverable.** This includes:
+   - HTTP basic-auth passwords for health check endpoints (health-check.key)
+   - OIDC `client_secret` (secret-encryption.key)
+   - SMTP `smtp_password` (secret-encryption.key)
+   - TOTP `totp_secret` for all users (secret-encryption.key)
+
+2. **If you have a backup** of the key files: restore them to `/etc/patch-manager/keys/` with `0600` permissions. The service will read the restored keys on next start.
+
+3. **If you do NOT have a backup**: re-provision the affected secrets:
+   - For OIDC: re-enter the `client_secret` from the IdP's app registration
+   - For SMTP: re-enter the SMTP password
+   - For TOTP: all users must re-enroll MFA (their existing TOTP secrets are unrecoverable)
+   - For health-check basic auth: re-enter the password in each health check configuration
+
+---
+
+## Key Rotation
+
+Key rotation is **not yet supported** (tracked as a follow-up issue). If a key is compromised:
+
+1. Generate a new key: `rm /etc/patch-manager/keys/secret-encryption.key` (service will auto-generate on next start)
+2. Re-encrypt all secrets in the database using the `migrate-secrets` binary (see [README of the helper](../../crates/migrate-secrets/src/main.rs))
+3. Update any external systems that depended on the old secrets (e.g., IdP app registration)
+
+For a planned rotation (without compromise), the procedure is the same but coordinated with a maintenance window.
+
+---
+
+## Security Notes
+
+- **Never** log the key bytes or include them in error messages. The `crypto::load_or_create_key()` function returns the key but callers should never `tracing::error!` the value.

+# Reverse Proxy Deployment Runbook
+
+**Audience:** Operators deploying `pm-web` behind a reverse proxy (nginx,
+HAProxy, Cloudflare, AWS ALB, etc.).
+
+**Related:**
+- `docs/security-review.md` §1.3 (IP Whitelist Enforcement)
+- `tasks/ip-allowlist-spec.md` §7 (Risk Analysis)
+- Issue [#3](https://github.com/Draco-Lunaris/Linux-Patch-Manager/issues/3)
+
+---
+
+## TL;DR
+
+If you front `pm-web` with a reverse proxy, you **MUST** add the proxy's
+IP address (or CIDR) to `security.trusted_proxies` in
+`/etc/patch-manager/config.toml`. If you do not, the IP allowlist will
+evaluate against the proxy's IP (not the real client) and will return
+`403 forbidden_ip` for legitimate traffic.
+
+## Why
+
+Starting with the IP-allowlist hardening in issue #3, `pm-web` no longer
+trusts `X-Forwarded-For` by default. The default behavior is **strict**:
+
+1. The server reads the socket peer IP from `ConnectInfo<SocketAddr>`.
+2. The server checks that IP against `security.ip_whitelist`.
+3. `X-Forwarded-For` is **ignored** unless the socket peer is in
+   `security.trusted_proxies`.
+
+When you put a reverse proxy in front, every connection's socket peer IP
+is the proxy's address. Without `trusted_proxies` set, the proxy's IP is
+checked against your allowlist — and unless your allowlist happens to
+include the proxy (which would defeat the purpose of the allowlist),
+the request is denied.
+
+## How to Fix
+
+1. Identify the **egress IP** of your reverse proxy (the IP `pm-web`
+   sees as the immediate TCP peer). This is typically:
+   - nginx: the IP nginx binds to internally, or the host's IP if nginx
+     runs on the same host as `pm-web` (port forward).
+   - Cloudflare: see
+     [Cloudflare IP ranges](https://www.cloudflare.com/ips/).
+   - AWS ALB / NLB: the ALB/NLB's private IP from the VPC.
+   - HAProxy: the bind address.
+
+2. Add the IP (or CIDR for multiple hops) to `trusted_proxies` in
+   `/etc/patch-manager/config.toml`:
+
+   ```toml
+   [security]
+   ip_whitelist = ["10.0.0.0/8"]            # example: corporate clients
+   trusted_proxies = ["172.16.5.10/32"]     # example: reverse proxy egress
+   ```
+
+3. **Restart `pm-web`** for the config to take effect. The
+   `trusted_proxies` field is read at startup; runtime updates are
+   supported via `AuthConfig::update_trusted_proxies` but not yet
+   exposed through a settings endpoint.
+
+4. Verify by tailing the logs and confirming that requests with
+   `X-Forwarded-For: <allowed-client-ip>` succeed (status 200/401, NOT
+   403) when the request comes through the proxy.
+
+## Multi-hop Proxy Chains
+
+If you have multiple proxies in front of `pm-web` (e.g., Cloudflare →
+nginx → pm-web), add **each hop you control** to `trusted_proxies`:
+
+```toml
+trusted_proxies = [
+    "172.16.5.10/32",   # nginx egress (immediate peer)
+    "10.0.0.0/8",       # internal network (in case nginx runs on a different host)
+]
+```
+
+The resolver picks the leftmost entry of `X-Forwarded-For` when the
+immediate peer is in `trusted_proxies`. With two trusted hops, the
+resolver will pick the leftmost untrusted IP (the real client).
+
+## Reverse Proxy Headers (recommended)
+
+In addition to the `trusted_proxies` config, configure your reverse
+proxy to:
+
+- **Append** to `X-Forwarded-For` (not replace) so the chain is
+  preserved through multiple hops.
+- Set `X-Real-IP` (optional, informational; pm-web currently uses
+  `X-Forwarded-For`).
+- Forward the original `Host` header so SAML/OIDC redirects work
+  correctly.
+- Do **not** strip the `Authorization` header.
+
+### nginx example
+
+```nginx
+location /api/ {
+    proxy_pass http://127.0.0.1:12443;
+    proxy_set_header Host              $host;
+    proxy_set_header X-Real-IP         $remote_addr;
+    proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+}
+```
+
+The `proxy_add_x_forwarded_for` directive appends, which is what you want.
+
+## Troubleshooting
+
+### All requests return 403 forbidden_ip
+
+- Check that `trusted_proxies` is set and contains the proxy's IP.
+- Check that the proxy's IP is correct (run `ss -tnp` on the pm-web
+  host to see the actual peer address).
+- Check `tracing` logs for `reason = "unresolvable_client_ip"` — this
+  means the `ConnectInfo<SocketAddr>` extension is missing (the
+  listener wasn't built with `into_make_service_with_connect_info`).
+
+### XFF is being ignored
+
+- Check that the immediate peer's IP is in `trusted_proxies`. If the
+  immediate peer is NOT in `trusted_proxies`, XFF is ignored (correct
+  behavior).
+- Check the XFF format: pm-web parses the leftmost entry, trimmed of
+  whitespace. A malformed leftmost entry falls back to the socket peer.
+
+### Multiple IPs in XFF and only the last hop is trusted
+
+- If you have one trusted proxy and one untrusted, the resolver will
+  only use XFF when the immediate peer (the trusted one) is in the
+  list. The XFF is parsed leftmost-first, so the real client IP (leftmost
+  untrusted hop) is used.
+- If neither hop is in `trusted_proxies`, XFF is ignored and the
+  socket peer IP (the immediate proxy) is used. Add the immediate
+  proxy to `trusted_proxies` to fix.

-All security controls are implemented as specified in the system requirements.
+**Description:**
+Private key file `client.key` and public certificates (`client.crt`, `ca.crt`) were committed
+to version control in `crates/pm-agent-client/certs/`. Committed private keys are a critical
+security risk: anyone with repository access can impersonate agents or decrypt captured TLS traffic.
+
+**Status:** ✅ RESOLVED
+
+**Remediation Applied:**
+1. Removed all cert files from git tracking (`git rm --cached`)
+2. Added `*.key`, `*.key.pem` and `crates/pm-agent-client/certs/` to `.gitignore`
+3. Updated `pm-agent-client` doc examples to use `std::fs::read()` instead of `include_bytes!`
+4. Added `gitleaks` secret scanning to CI pipeline
+5. Added README to `crates/pm-agent-client/certs/` explaining runtime cert generation
+6. Git history will be purged with `git filter-repo` after PR merge
+
+**Key Rotation:**
+These keys were dev/test only. No production key rotation is needed. All committed keys
+should be considered compromised and must not be used in production.
