feat(M44): Google CAS issuer connector

Google Cloud Certificate Authority Service integration via REST API
with OAuth2 service account auth (JWT→access token). Synchronous
issuance model, CA pool selection, mutex-guarded token caching,
revocation with RFC 5280 reason mapping. No Google SDK dependency —
all stdlib. 19 tests with httptest mock OAuth2 + CAS API.

+certctl is a self-hosted platform that automates the entire certificate lifecycle — from issuance through renewal to deployment — with zero human intervention. It works with any certificate authority, deploys to any server, and keeps private keys on your infrastructure where they belong. It's free, self-hosted, and covers the same lifecycle that enterprise platforms charge $100K+/year for.
 
-> **Next release:** v2.1.0 will be tagged after the full V2 feature suite passes manual QA across all 34 sections of the [testing guide](docs/testing-guide.md). Automated CI (1,471 Go tests + 193 frontend tests) gates every commit; the manual playbook covers integration, deployment, and UX verification that unit tests can't reach.

 ## Why certctl Exists
 
-Certificate lifecycle tooling today falls into two camps: expensive enterprise platforms (Venafi, Keyfactor, Sectigo) that cost six figures and take months to deploy, or single-purpose tools (cert-manager, certbot) that handle one slice of the problem. If you run a mixed infrastructure — some NGINX, some Apache, a few HAProxy nodes, maybe an F5 — and you need to manage certificates from multiple CAs, there's nothing self-hosted that covers the full lifecycle without vendor lock-in.
+Certificate lifecycle tooling today falls into two camps: expensive enterprise platforms (Venafi, Keyfactor, Sectigo) that cost six figures and take months to deploy, or single-purpose tools (cert-manager, certbot) that handle one slice of the problem. If you run a mixed infrastructure — some NGINX, some Apache, a few HAProxy nodes, IIS on Windows, maybe an F5 — and you need to manage certificates from multiple CAs, there's nothing self-hosted that covers the full lifecycle without vendor lock-in.
 
-certctl fills that gap. It's **CA-agnostic** — the issuer connector interface means you can plug in any certificate authority: a self-signed local CA for dev, Let's Encrypt via ACME for public certs, Smallstep step-ca for your private PKI, your enterprise ADCS via sub-CA mode, or any custom CA through a shell script adapter. You're never locked to a single CA vendor, and you can run multiple issuers simultaneously for different certificate types.

Run multiple issuers simultaneously for different certificate types.
 
-It's also **target-agnostic**. Agents deploy certificates to NGINX, Apache, HAProxy, Traefik, and Caddy — all using the same pluggable connector model for any server that accepts cert files. The control plane never initiates outbound connections — agents poll for work, which means certctl works behind firewalls, across network zones, and in air-gapped environments.

+
+## Who Is This For
+
+**Platform engineering and DevOps teams** managing 10–500+ certificates across mixed infrastructure who need automated renewal, deployment, and a single dashboard for visibility. If you're currently running certbot cron jobs, manually renewing certs, or stitching together scripts — certctl replaces all of that.
+
+**Security and compliance teams** who need an immutable audit trail, certificate ownership tracking, policy enforcement, and evidence for SOC 2, PCI-DSS 4.0, or NIST SP 800-57 audits.
+
+**Small teams without enterprise budgets** who need the lifecycle automation that Venafi and Keyfactor provide but can't justify six-figure licensing for a 50-server environment.
 
 ## What It Does
 
-certctl gives you a single pane of glass for every TLS certificate in your organization:
+- **Certificates renew and deploy themselves.** The scheduler monitors expiration, creates renewal jobs, issues certificates through your CA, and deploys them to target servers — all without human intervention. ACME ARI (RFC 9702) lets your CA tell certctl exactly when to renew.
 
-- **Web dashboard** — 22 operational pages: certificate inventory, deployment timeline with TLS verification, bulk operations (renew/revoke/reassign), discovery triage, network scan management, approval workflows, audit trail with CSV/JSON export, agent fleet overview with OS/arch grouping, short-lived credential monitoring, digest email preview
-- **REST API** — 99 endpoints under `/api/v1/` + `/.well-known/est/` for complete automation, with sparse fields, sort, cursor pagination, and time-range filters
-- **Agents** — generate private keys locally (ECDSA P-256), discover existing certs on disk (PEM/DER), submit CSRs only (private keys never leave your servers)
-- **Network scanner** — discovers certificates on TLS endpoints across CIDR ranges without requiring agents, concurrent scanning with configurable timeouts
-- **Certificate export** — PEM (JSON or file download) and PKCS#12 formats, with audit trail; private keys never included
-- **S/MIME + EKU support** — issue certificates with emailProtection, codeSigning, timeStamping, clientAuth EKUs; email SAN routing for S/MIME
-- **EST server** (RFC 7030) — device and WiFi certificate enrollment via industry-standard protocol
-- **Post-deployment verification** — agent-side TLS probe confirms the target serves the correct certificate by SHA-256 fingerprint match
-- **Approval workflows** — require human sign-off on renewals before deployment
-- **Background scheduler** — 7 automated loops: renewal checks, job processing, agent health, notifications, short-lived cert expiry, network scanning, and scheduled certificate digest emails
-- **ACME Renewal Information (ARI, RFC 9702)** — CA-directed renewal timing; certctl asks the CA when to renew instead of using fixed thresholds
-- **Scheduled certificate digest emails** — HTML digest with certificate stats, expiration timeline, and job health; optional daily briefing via SMTP
-- **Helm chart** — Production-ready Kubernetes deployment with server, PostgreSQL, and agent DaemonSet
+- **You see everything in one place.** A 25-page operational dashboard shows every certificate across every server: status, ownership, expiration timeline, deployment history with TLS verification, discovery triage, and real-time agent fleet health. Bulk operations (renew, revoke, reassign) work across selections.
 
-For the full capability breakdown — revocation infrastructure, policy engine, observability, EST enrollment, and more — see the [Feature Inventory](docs/features.md).
+- **Private keys never leave your servers.** Agents generate ECDSA P-256 keys locally and submit only the CSR. The control plane never touches private keys. Post-deployment TLS verification confirms the right certificate is actually being served.
+
+- **Discover what you don't know about.** Agents scan filesystems for existing PEM/DER certificates. The network scanner probes TLS endpoints across CIDR ranges without requiring agents. Both feed into a triage workflow where you claim, dismiss, or import discovered certificates.
+
+- **Everything is auditable.** Immutable append-only audit trail records every lifecycle action, every API call, and every approval decision. Certificate digest emails deliver daily briefings. Prometheus metrics endpoint for Grafana dashboards.
+
+- **Multiple interfaces for different workflows.** REST API (97 endpoints) for automation, CLI for scripting, MCP server for AI assistants (Claude, Cursor, Windsurf), EST server (RFC 7030) for device enrollment, Helm chart for Kubernetes, and the web dashboard for day-to-day operations.
+
+For the full capability breakdown — revocation infrastructure (CRL + OCSP), policy engine, certificate profiles, S/MIME support, approval workflows, and more — see the [Feature Inventory](docs/features.md).

-### CI Pipeline
-
-Every push and PR runs: `go vet`, `go test -race` (race detection), `golangci-lint` (11 linters including gosec and bodyclose), `govulncheck` (dependency CVE scanning), and per-layer coverage thresholds (service 60%, handler 60%, domain 40%, middleware 50%). Frontend CI runs TypeScript type checking, Vitest tests, and Vite production build. See `.github/workflows/ci.yml` for details.
-
-### Docker Compose
-
-```bash
-make docker-up          # Start stack (server + postgres + agent)
-make docker-down        # Stop stack
-make docker-logs-server # Server logs
-make docker-logs-agent  # Agent logs
-make docker-clean       # Stop + remove volumes
-```
-
-## Security
-
-### Private Key Management
-- **Agent keygen mode (default)**: Agents generate ECDSA P-256 keys locally and store them with 0600 permissions in `CERTCTL_KEY_DIR` (default `/var/lib/certctl/keys`). Only the CSR (public key) is sent to the control plane. Private keys never leave agent infrastructure.
-- **Server keygen mode (demo only)**: Set `CERTCTL_KEYGEN_MODE=server` for development/demo with Local CA. The control plane generates RSA-2048 keys server-side. A log warning is emitted at startup.
-
-### Authentication
-- Agent-to-server: API key (registered at agent creation)
-- API key and JWT auth types supported; `none` for demo/development
-- Auth type and secret configured via `CERTCTL_AUTH_TYPE` and `CERTCTL_AUTH_SECRET`
-
-### CORS
-- **Deny-by-default**: Empty `CERTCTL_CORS_ORIGINS` blocks all cross-origin requests. Operators must explicitly list allowed origins (comma-separated) or set `*` for development.
-
-### Input Validation
-- Shell command injection prevention on all connector scripts (strict character whitelist, no metacharacters)
-- RFC 1123 domain name validation, base64url ACME token validation
-- SSRF protection in network scanner (loopback, link-local, multicast, broadcast ranges filtered)
-
-### Concurrency Safety
-- Scheduler loops protected by `sync/atomic.Bool` idempotency guards — duplicate ticks are skipped
-- Graceful shutdown waits up to 30 seconds for in-flight work before database close
-
-### Audit Trail
-- Immutable append-only log in PostgreSQL (`audit_events` table)
-- Every lifecycle action attributed to an actor with timestamp and resource reference
-- No update or delete operations on audit records
-- Every API call recorded to audit trail with method, path, actor, SHA-256 body hash, response status, and latency

+## Security
+
+certctl is designed with a security-first architecture. Agents generate ECDSA P-256 keys locally — private keys never touch the control plane. API key auth is enforced by default with SHA-256 hashing and constant-time comparison. CORS is deny-by-default. All connector scripts are validated against shell injection. The network scanner filters reserved IP ranges (SSRF protection). Scheduler loops use atomic idempotency guards. Every API call is recorded to an immutable audit trail with actor attribution, SHA-256 body hash, and latency tracking. See the [Architecture Guide](docs/architecture.md) for the full security model.

 ### Design Principles
 
 1. **Private Key Isolation** — Agents generate ECDSA P-256 keys locally and submit CSRs only. Private keys never touch the control plane. Server-side keygen available via `CERTCTL_KEYGEN_MODE=server` for demo only.
-2. **Pull-Only Deployment** — The server never initiates outbound connections to agents or targets. Agents poll for work. For network appliances and agentless targets, a proxy agent in the same network zone executes deployments via the target's API. This keeps the control plane firewalled off and limits credential scope to the proxy agent's zone.
+2. **Pull-Only Deployment** — The server never initiates outbound connections to agents or targets. Agents poll for work and receive only jobs assigned to their targets (routed via `agent_id` on jobs or through target→agent relationships). For network appliances and agentless targets, a proxy agent in the same network zone executes deployments via the target's API. This keeps the control plane firewalled off and limits credential scope to the proxy agent's zone.
 3. **Sub-CA Capable** — The Local CA can operate as a subordinate CA under an enterprise root (e.g., ADCS). Load a pre-signed CA cert+key from disk and all issued certs chain to the enterprise trust hierarchy. Self-signed mode remains the default for development/demos.
 4. **GUI as Primary Interface** — The web dashboard is the operational control plane, not a secondary viewer. Every backend feature ships with its corresponding GUI surface.
 5. **Decoupled Operations** — Agents operate autonomously; the control plane coordinates but doesn't block agent function

 ### Agents
 
-Lightweight Go processes that run on or near your infrastructure. Agents generate ECDSA P-256 private keys locally, create CSRs, and submit them to the control plane for signing — private keys never leave agent infrastructure. Agents also handle certificate deployment to target systems (NGINX, Apache httpd, HAProxy fully implemented; F5 BIG-IP, IIS interface only with V2 implementations planned) and report job status. They communicate with the control plane via HTTP and authenticate with API keys.

 The agent runs two background loops: a heartbeat (every 60 seconds) to signal it's alive, and a work poll (every 30 seconds) to check for actionable jobs via `GET /api/v1/agents/{id}/work`. Jobs may be `AwaitingCSR` (agent needs to generate key + submit CSR) or `Deployment` (agent needs to deploy a certificate). Private keys are stored in `CERTCTL_KEY_DIR` (default `/var/lib/certctl/keys`) with 0600 permissions.

 **ACME Renewal Information (ARI, RFC 9702):** The ACME connector supports CA-directed renewal timing via the `GetRenewalInfo()` method. Instead of using fixed thresholds (e.g., renew 30 days before expiry), the CA tells certctl when to renew by providing a `suggestedWindow` with start and end times. This is useful for distributing renewal load during maintenance windows and coordinating mass-revocation scenarios. Enable with `CERTCTL_ACME_ARI_ENABLED=true`. Cert ID is computed as `base64url(SHA-256(DER cert))` per RFC 9702. If the CA doesn't support ARI (404 from the ARI endpoint), certctl automatically falls back to threshold-based renewal — no operator intervention required. Errors from the CA are logged as warnings.

-### Coming in V2.1
+### Built-in: Vault PKI
 
-The following issuer connectors are planned for the v2.1.0 release:
+The Vault PKI connector integrates with HashiCorp Vault's PKI secrets engine using its native `/sign` API with token-based authentication. This is ideal for organizations using Vault as their internal certificate authority — synchronous issuance without the complexity of ACME or challenge solving.
 
-- **Vault PKI** — HashiCorp Vault's PKI secrets engine (`/v1/{mount}/sign/{role}` API) for organizations using Vault as their internal CA. Token auth, configurable mount and role.
-- **DigiCert** — Commercial CA integration via DigiCert CertCentral REST API. Async order model (submit → poll for completion). OV/EV certificate support.
+**Configuration:**
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `CERTCTL_VAULT_ADDR` | — | Vault server address (e.g., `https://vault.internal:8200`) |
+| `CERTCTL_VAULT_TOKEN` | — | Vault auth token with permissions on the PKI mount |
+| `CERTCTL_VAULT_MOUNT` | `pki` | PKI secrets engine mount path |
+| `CERTCTL_VAULT_ROLE` | — | PKI role name for certificate signing |
+| `CERTCTL_VAULT_TTL` | `8760h` | Certificate validity period (TTL) |
+
+The connector is registered in the issuer registry under `iss-vault`. Vault issues certificates synchronously via the `/v1/{mount}/sign/{role}` API with `X-Vault-Token` header authentication. The issued certificate is parsed to extract serial number, validity dates, and chain information.
+
+**Note:** CRL and OCSP are managed by Vault itself. Clients should validate certificate status against Vault's own CRL/OCSP endpoints (`GET /v1/{mount}/crl` and Vault's OCSP responder). certctl does not generate local CRL/OCSP for Vault-issued certificates. Revocation is recorded locally but Vault is the authoritative source.
+
+Location: `internal/connector/issuer/vault/vault.go`
+
+### Built-in: DigiCert CertCentral
+
+The DigiCert connector integrates with DigiCert's CertCentral REST API for ordering and managing certificates from DigiCert's commercial CA. It supports both Domain Validated (DV) and Organization/Extended Validated (OV/EV) certificates, with async order processing.
+
+**Configuration:**
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `CERTCTL_DIGICERT_API_KEY` | — | DigiCert API key (X-DC-DEVKEY header) |
+| `CERTCTL_DIGICERT_ORG_ID` | — | DigiCert organization ID |
+| `CERTCTL_DIGICERT_PRODUCT_TYPE` | `ssl_basic` | Certificate product (e.g., `ssl_basic`, `ssl_plus`, `ssl_ev`) |
+| `CERTCTL_DIGICERT_BASE_URL` | `https://www.digicert.com/services/v2` | DigiCert API base URL |
+
+The connector submits certificate orders to DigiCert's `/order/certificate/create` API. DV certificates may issue immediately; OV/EV certificates require validation (handled by DigiCert) and poll-based completion. The connector periodically checks order status via `/order/certificate/{order_id}` until the certificate is available.
+
+**Authentication:** API key passed via `X-DC-DEVKEY` header, with organization ID in request body.
+
+**Note:** CRL and OCSP are managed by DigiCert. Clients should validate certificate status against DigiCert's infrastructure. certctl records the revocation locally but does not notify DigiCert for revocation — use DigiCert's dashboard for revocation management.
+
+Location: `internal/connector/issuer/digicert/digicert.go`
+
+### Built-in: Sectigo SCM
+
+The Sectigo connector integrates with Sectigo Certificate Manager's REST API for ordering and managing DV, OV, and EV certificates. Like DigiCert, it uses an async order model: submit an enrollment, receive an sslId, then poll for completion.
+
+**Configuration:**
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `CERTCTL_SECTIGO_CUSTOMER_URI` | — | Sectigo customer URI (organization identifier) |
+| `CERTCTL_SECTIGO_LOGIN` | — | API account login |
+| `CERTCTL_SECTIGO_PASSWORD` | — | API account password |
+| `CERTCTL_SECTIGO_ORG_ID` | — | Organization ID (integer) |
+| `CERTCTL_SECTIGO_CERT_TYPE` | — | Certificate type ID (integer, from `/ssl/v1/types`) |
+| `CERTCTL_SECTIGO_TERM` | `365` | Certificate validity in days |
+| `CERTCTL_SECTIGO_BASE_URL` | `https://cert-manager.com/api` | Sectigo API base URL |
+
+The connector submits certificate enrollments to Sectigo's `/ssl/v1/enroll` API. DV certificates may issue immediately; OV/EV certificates require validation (handled by Sectigo) and poll-based completion. The connector periodically checks enrollment status via `/ssl/v1/{sslId}` and downloads the PEM bundle via `/ssl/v1/collect/{sslId}/pem` when issued.
+
+**Authentication:** Three custom headers on every request — `customerUri`, `login`, and `password`.
+
+**Note:** CRL and OCSP are managed by Sectigo. certctl records revocations locally and notifies Sectigo via `/ssl/v1/revoke/{sslId}`.
+

+### Built-in: Google CAS
+
+Google Cloud Certificate Authority Service — managed private CA on GCP. Synchronous issuance via CAS REST API with OAuth2 service account auth.
+
+| Setting | Required | Default | Description |
+|---------|----------|---------|-------------|
+| `CERTCTL_GOOGLE_CAS_PROJECT` | Yes | — | GCP project ID |
+| `CERTCTL_GOOGLE_CAS_LOCATION` | Yes | — | GCP region (e.g., `us-central1`) |
+| `CERTCTL_GOOGLE_CAS_CA_POOL` | Yes | — | CA pool name |
+| `CERTCTL_GOOGLE_CAS_CREDENTIALS` | Yes | — | Path to service account JSON |
+| `CERTCTL_GOOGLE_CAS_TTL` | No | `8760h` | Default certificate TTL |
+
+**Authentication:** OAuth2 service account. The connector reads a service account JSON file, signs a JWT with the private key, and exchanges it for an access token at Google's token endpoint. Tokens are cached and refreshed automatically (5 min before expiry).
+
+**Note:** CRL and OCSP are managed by Google CAS directly. certctl records revocations locally and notifies Google CAS via the revoke endpoint.

+- **AWS ACM Private CA** — AWS-managed private CA
 
 Note: ADCS (Active Directory Certificate Services) integration is handled via the **sub-CA mode** of the Local CA issuer, not as a separate connector. certctl operates as a subordinate CA with its signing certificate issued by ADCS, so all certctl-issued certs chain to the enterprise ADCS root.

+### Built-in: Envoy
+
+The Envoy connector uses file-based certificate delivery — it writes certificate and key files to a directory that Envoy watches via its SDS (Secret Discovery Service) file-based configuration or static `filename` references in the bootstrap config. When files change, Envoy automatically picks up the new certificates without requiring a reload command.
+
+Configuration:
+```json
+{
+  "cert_dir": "/etc/envoy/certs",
+  "cert_filename": "cert.pem",
+  "key_filename": "key.pem",
+  "chain_filename": "chain.pem",
+  "sds_config": true
+}
+```
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| `cert_dir` | string | (required) | Directory where Envoy watches for certificate files |
+| `cert_filename` | string | `cert.pem` | Filename for the certificate (leaf + chain unless `chain_filename` is set) |
+| `key_filename` | string | `key.pem` | Filename for the private key |
+| `chain_filename` | string | (empty) | If set, chain is written to a separate file instead of appended to the cert |
+| `sds_config` | bool | `false` | If true, writes an `sds.json` file for Envoy's file-based SDS provider |
+
+When `sds_config` is `true`, the connector writes an SDS JSON file (`{cert_dir}/sds.json`) containing a `tls_certificate` resource that points to the cert and key file paths. Envoy's file-based SDS (`path_config_source`) watches this file for changes, providing automatic hot-reload of certificates. This is the recommended approach for production Envoy deployments using dynamic TLS configuration.
+
+When `sds_config` is `false` (the default), the connector simply writes cert and key files. Use this mode when Envoy's bootstrap config references the cert/key files directly via static `filename` fields in the TLS context.
+
+Location: `internal/connector/target/envoy/envoy.go`
+
+### Built-in: Postfix / Dovecot
+
+The Postfix/Dovecot connector is a dual-mode mail server TLS connector. It writes certificate, key, and chain files to configured paths and reloads the mail service. The `mode` field selects between Postfix MTA and Dovecot IMAP/POP3, which determines default file paths and reload commands.
+
+This connector pairs with certctl's S/MIME certificate support (email protection EKU, email SAN routing) for a complete email infrastructure story — TLS for transport encryption, S/MIME for end-to-end message signing and encryption.
+
+**Postfix configuration:**
+```json

 ### F5 BIG-IP (Interface Only)
 
 The F5 BIG-IP target connector interface is defined with the iControl REST flow mapped out, but the actual API calls are not yet implemented. F5 appliances can't run agents directly, so this connector uses the **proxy agent pattern**: a designated agent in the same network zone picks up F5 deployment jobs and calls the iControl REST API. The server assigns the work; the proxy agent executes it.

-The IIS target connector supports two planned deployment modes:
+The IIS target connector supports two deployment modes — agent-local (recommended) and proxy agent WinRM for agentless targets.
 
-**Agent-local (recommended):** A Windows agent runs directly on the IIS server and deploys certificates using PowerShell — `Import-PfxCertificate` to install into the certificate store and `Set-WebBinding` to bind to the IIS site. This is the preferred approach: no remote access needed, no credential management, same pull-based model as NGINX/Apache/HAProxy.
+**Agent-local (recommended):** A Windows agent runs directly on the IIS server and deploys certificates using PowerShell — `Import-PfxCertificate` to install into the certificate store and `Set-WebBinding` to bind to the IIS site. The agent handles PEM-to-PFX conversion via `go-pkcs12`, computes SHA-1 thumbprint from the certificate, and executes parameterized PowerShell scripts for injection-safe binding management. This is the preferred approach: no remote access needed, no credential management, same pull-based model as NGINX/Apache/HAProxy.
 
-**Proxy agent WinRM (for agentless targets):** For Windows servers where you don't want to install an agent, a nearby Windows agent acts as a proxy and reaches the IIS box via WinRM. The proxy agent picks up the deployment job, transfers the PFX bundle over WinRM, and runs the PowerShell commands remotely. WinRM credentials are stored on the proxy agent, not on the control plane.
+**Proxy agent WinRM (for agentless targets):** For Windows servers where you don't want to install an agent, a Linux or Windows proxy agent in the same network zone connects via WinRM (Windows Remote Management) and executes PowerShell commands remotely. The PFX bundle is base64-encoded, transferred inline in the WinRM session, decoded to a temp file on the remote host, imported, and the temp file is cleaned up in a `try/finally` block. WinRM credentials are configured on the target, not on the control plane. Uses the `masterzen/winrm` Go library with support for Basic, NTLM, and Kerberos authentication.
 
-Configuration (defined, not yet functional):
+**Agent-local configuration:**
 ```json
 {
-  "mode": "local",

+  "ip_address": "*",
+  "binding_info": "www.example.com"
 }
 ```
 
-When `mode` is `"local"`, the `winrm_*` fields are ignored. When `mode` is `"proxy"`, the agent connects to the remote IIS server via WinRM using the provided credentials.

+# Deployment Examples
+
+Five turnkey docker-compose scenarios, each runnable in under 5 minutes. Pick the one closest to your setup.
+
+## Which Example Should I Use?
+
+| I need to... | Example | Issuer | Target |
+|--------------|---------|--------|--------|
+| Get Let's Encrypt certs for NGINX on a public server | [ACME + NGINX](#acme--nginx) | ACME (HTTP-01) | NGINX |
+| Issue wildcard certs without opening port 80 | [Wildcard DNS-01](#wildcard-dns-01) | ACME (DNS-01) | Any |
+| Run an internal CA for services behind a firewall | [Private CA + Traefik](#private-ca--traefik) | Local CA | Traefik |
+| Use Smallstep step-ca as my PKI backend | [step-ca + HAProxy](#step-ca--haproxy) | step-ca | HAProxy |
+| Manage both public and internal certs from one dashboard | [Multi-Issuer](#multi-issuer) | ACME + Local CA | Mixed |
+
+**Already using another tool?** See the migration sections below each example for Certbot, acme.sh, and cert-manager users.
+
+---
+
+## ACME + NGINX
+
+**Scenario:** You have one or more public-facing domains, NGINX as the reverse proxy, and want automated Let's Encrypt certificates with HTTP-01 challenges.
+
+**What it deploys:** certctl server + PostgreSQL + certctl agent + NGINX, all on one Docker network. The agent generates keys locally (ECDSA P-256), submits CSRs to the server, receives signed certs from Let's Encrypt, and deploys them to NGINX with automatic reload.
+
+**Prerequisites:** A domain pointing to your server, ports 80 and 443 open, Docker Compose v20.10+.
+
+```bash
+cd examples/acme-nginx
+cp .env.example .env   # Edit with your domain and email
+docker compose up -d
+```
+
+The full walkthrough — including how HTTP-01 challenges work, adding multiple domains, switching to staging for testing, and a production checklist — is in the [example README](../examples/acme-nginx/acme-nginx.md).
+
+**Migrating from Certbot?** certctl discovers your existing `/etc/letsencrypt/live/` certificates automatically. You keep your ACME account, disable the Certbot cron, and certctl takes over renewal with centralized visibility and deployment verification. The step-by-step process is in [Migrating from Certbot](migrate-from-certbot.md).
+
+---
+
+## Wildcard DNS-01
+
+**Scenario:** You need wildcard certificates (`*.example.com`) or your servers aren't reachable from the internet (no port 80). DNS-01 validates ownership by creating a TXT record at your DNS provider.
+
+**What it deploys:** certctl server + PostgreSQL + certctl agent. Includes a Cloudflare DNS hook script as a working reference — swap in your own DNS provider (Route53, Azure DNS, Google Cloud DNS, or any provider with an API).
+
+**Prerequisites:** A domain, API credentials for your DNS provider, Docker Compose.
+
+```bash
+cd examples/acme-wildcard-dns01
+cp .env.example .env   # Edit with domain, email, DNS provider credentials
+docker compose up -d
+```
+
+The full walkthrough — including DNS-PERSIST-01 (set a TXT record once, never touch DNS again on renewals), adapting scripts for other providers, and propagation troubleshooting — is in the [example README](../examples/acme-wildcard-dns01/acme-wildcard-dns01.md).
+
+**Migrating from acme.sh?** Your existing `dns_*` hook scripts are compatible with certctl's DNS-01 — they use the same pattern (shell scripts creating TXT records). The migration guide covers script adaptation, discovery of existing acme.sh certificates, and phasing out the acme.sh cron. See [Migrating from acme.sh](migrate-from-acmesh.md).
+
+---
+
+## Private CA + Traefik
+
+**Scenario:** Internal services that don't need public CA validation. You run your own certificate authority — either a self-signed root for development, or a subordinate CA chained to your enterprise root (e.g., Active Directory Certificate Services).
+
+**What it deploys:** certctl server + PostgreSQL + certctl agent + Traefik. The Local CA issuer signs certificates directly. Traefik watches a cert directory and auto-reloads when new files appear.
+
+**Prerequisites:** Docker Compose. For sub-CA mode, you'll need a CA certificate and key signed by your enterprise root.
+
+```bash
+cd examples/private-ca-traefik
+docker compose up -d    # Self-signed mode (no .env needed for demo)
+```
+
+The full walkthrough — including sub-CA setup with `CERTCTL_CA_CERT_PATH` and `CERTCTL_CA_KEY_PATH`, creating certificates via the API, monitoring deployments, and production hardening — is in the [example README](../examples/private-ca-traefik/private-ca-traefik.md).
+
+---
+
+## step-ca + HAProxy
+
+**Scenario:** You use Smallstep's step-ca as your private PKI and want automated lifecycle management for certificates deployed to HAProxy load balancers.
+
+**What it deploys:** certctl server + PostgreSQL + certctl agent + step-ca (with JWK provisioner) + HAProxy. certctl issues certs via step-ca's native `/sign` API, combines them into HAProxy's expected PEM format (cert + chain + key in one file), and reloads HAProxy.
+
+**Prerequisites:** Docker Compose.
+
+```bash
+cd examples/step-ca-haproxy
+docker compose up -d
+```
+
+The full walkthrough — including step-ca provisioner configuration, integrating with an existing step-ca instance, HAProxy PEM format details, and advanced features (approval workflows, policy-based renewal, multi-instance HAProxy) — is in the [example README](../examples/step-ca-haproxy/step-ca-haproxy.md).
+
+---
+
+## Multi-Issuer
+
+**Scenario:** You manage both public-facing services (needing Let's Encrypt or another public CA) and internal services (using a private CA) and want a single dashboard for everything.
+
+**What it deploys:** certctl server + PostgreSQL + certctl agent configured with both an ACME issuer and a Local CA issuer. Demonstrates issuer assignment via profiles — public services get ACME certs, internal services get Local CA certs, all visible in one inventory.
+
+**Prerequisites:** Docker Compose. For real ACME certs, a public domain and port 80 access.
+
+```bash
+cd examples/multi-issuer
+docker compose up -d
+```
+
+The full walkthrough — including profile-based issuer assignment, testing with ACME staging, Local CA enterprise sub-CA mode, and scaling beyond Docker Compose — is in the [example README](../examples/multi-issuer/multi-issuer.md).
+
+**Using cert-manager for Kubernetes?** certctl complements cert-manager — cert-manager handles in-cluster certs, certctl handles everything outside: VMs, bare metal, network appliances, Windows servers. They can share the same CA (ACME, step-ca, Vault PKI). See [certctl for cert-manager Users](certctl-for-cert-manager-users.md).
+
+---
+
+## Beyond These Examples
+
+These 5 scenarios cover the most common deployment patterns, but certctl supports 7 issuer backends and 10 target connectors. Once you have the basics running, you can mix and match:
+
+**Issuers:** ACME (Let's Encrypt, ZeroSSL, Buypass, Google Trust Services), Local CA (self-signed or sub-CA), step-ca, Vault PKI, DigiCert CertCentral, OpenSSL/Custom CA script, Sectigo (coming soon).
+
+**Targets:** NGINX, Apache, HAProxy, Traefik, Caddy, Envoy, IIS (local PowerShell or WinRM proxy), Postfix, Dovecot, F5 BIG-IP (coming soon).
+
+See [Connector Reference](connectors.md) for configuration details on every issuer and target.

+## Part 35: ARI (RFC 9702) Scheduler Integration
+
+Tests that the renewal scheduler consults ARI before creating renewal jobs for ACME-issued certificates.
+
+### 35.1 ARI Defers Renewal When CA Says "Not Yet"
+
+**Prerequisite:** ACME issuer configured with `CERTCTL_ACME_ARI_ENABLED=true`, connected to a CA that supports ARI (e.g., Let's Encrypt staging). Certificate within the 30-day expiry window but the CA's `suggestedWindow.start` is in the future.
+
+```bash
+# Check scheduler logs for ARI deferral
+docker logs certctl-server 2>&1 | grep "ARI: renewal not yet suggested"
+```
+
+**Expected:** Log line showing `ARI: renewal not yet suggested by CA` with `cert_id`, `suggested_start`, `suggested_end`. No renewal job created for that cert.
+**PASS if** the scheduler skips renewal job creation when ARI says the window hasn't opened.
+
+### 35.2 ARI Triggers Renewal When CA Says "Now"
+
+**Prerequisite:** Same setup as 35.1, but the certificate's ARI `suggestedWindow.start` is in the past (CA is actively suggesting renewal).
+
+```bash
+# Check scheduler logs for ARI-triggered renewal
+docker logs certctl-server 2>&1 | grep "ARI: CA suggests renewal now"
+
+# Verify renewal job was created
+curl -s -H "Authorization: Bearer $API_KEY" \
+  "http://localhost:8443/api/v1/jobs?type=renewal" | jq '.data[] | select(.certificate_id == "<cert-id>")'
+```
+
+**Expected:** Log line showing `ARI: CA suggests renewal now`. Renewal job created with `renewal_trigger: ari` in the audit trail.
+**PASS if** a renewal job is created when ARI indicates the renewal window is open.
+
+### 35.3 ARI Fallback on Error
+
+**Prerequisite:** ACME issuer with `CERTCTL_ACME_ARI_ENABLED=true`, but the ARI endpoint is unreachable or returns an error (e.g., network issue, 500 from CA).
+
+```bash
+# Check scheduler logs for ARI fallback
+docker logs certctl-server 2>&1 | grep "ARI check failed, falling back"
+```
+
+**Expected:** Warning log `ARI check failed, falling back to threshold-based renewal`. Renewal proceeds normally using the configured expiration thresholds.
+**PASS if** renewal still works when ARI is unavailable, using threshold-based logic as fallback.
+
+---
+
+## Part 36: Agent Work Routing (M31)
+
+Tests that `GetPendingWork()` returns only jobs scoped to the requesting agent, and that deployment jobs have `agent_id` populated at creation time.
+
+### 36.1 Multi-Agent Routing
+
+**Prerequisite:** Two agents registered (`agent-web-01`, `agent-lb-01`), two targets (one per agent), one certificate mapped to both targets. Trigger renewal to create deployment jobs.
+
+```bash
+# Poll as agent-web-01 — should only see its deployment job
+curl -s -H "Authorization: Bearer $API_KEY" \
+  "http://localhost:8443/api/v1/agents/agent-web-01/work" | jq '.[] | .target_id'
+
+# Poll as agent-lb-01 — should only see its deployment job
+curl -s -H "Authorization: Bearer $API_KEY" \
+  "http://localhost:8443/api/v1/agents/agent-lb-01/work" | jq '.[] | .target_id'
+```
+
+**Expected:** Each agent receives only the deployment job for its assigned target. Agent-web-01 does NOT see agent-lb-01's job and vice versa.
+**PASS if** each agent's work response contains only jobs for targets it owns.
+
+### 36.2 Agent With No Targets Gets Empty Work
+
+**Prerequisite:** Register a new agent with no target assignments.
+
+```bash
+curl -s -H "Authorization: Bearer $API_KEY" \
+  "http://localhost:8443/api/v1/agents/agent-no-targets/work" | jq 'length'
+```
+
+**Expected:** Empty array (0 jobs).
+**PASS if** the response is an empty list.
+
+### 36.3 Deployment Jobs Have agent_id Populated
+
+**Prerequisite:** Deployment jobs created via renewal or manual trigger.
+
+```bash
+# Check that deployment jobs in the system have agent_id set
+curl -s -H "Authorization: Bearer $API_KEY" \
+  "http://localhost:8443/api/v1/jobs" | jq '[.data[] | select(.type == "Deployment") | .agent_id] | map(select(. != null)) | length'
+```
+
+**Expected:** All deployment jobs for targets with agent assignments have `agent_id` populated.
+**PASS if** deployment jobs have non-null `agent_id` values.

+
+### 39.2 Issue DV Certificate via DigiCert
+
+**Test:** Create a DV certificate order and track it to completion.
+
+```bash
+CERT_ID=$(curl -s -X POST -H "$AUTH" -H "$CT" \
+  "$SERVER/api/v1/certificates" \
+  -d '{
+    "common_name": "dv-test.example.com",
+    "issuer_id": "iss-digicert-prod",
+    "key_algorithm": "RSA-2048"
+  }' | jq -r '.id')
+
+JOB_ID=$(curl -s -X POST -H "$AUTH" \
+  "$SERVER/api/v1/certificates/$CERT_ID/renew" | jq -r '.job_id')

+  STATUS=$(curl -s -H "$AUTH" \
+    "$SERVER/api/v1/jobs/$JOB_ID" | jq -r '.status')
+  echo "Job status: $STATUS"
+  [ "$STATUS" = "Completed" ] && break
+  sleep 2
+done
+```
+
+**Expected:** Job eventually reaches Completed status with certificate issued.
+**PASS if** certificate has DigiCert serial number and chain.
+
+### 39.3 Verify Order ID Tracking
+
+**Test:** Check that the job record includes the DigiCert order ID for auditing.
+
+```bash
+curl -s -H "$AUTH" \
+  "$SERVER/api/v1/jobs/$JOB_ID" | jq '.metadata'
+```
+
+**Expected:** Metadata includes `order_id` from DigiCert for order tracking.
+**PASS if** audit trail shows the DigiCert order lifecycle.
+
+### 39.4 Async Poll Behavior
+
+**Test:** Verify the connector polls for certificate completion (OV certs take longer).
+
+```bash
+# Submit OV certificate order (requires validation)
+CERT_ID=$(curl -s -X POST -H "$AUTH" -H "$CT" \
+  "$SERVER/api/v1/certificates" \
+  -d '{
+    "common_name": "ov-test.example.com",
+    "issuer_id": "iss-digicert-prod",

+  }' | jq -r '.id')
+
+JOB_ID=$(curl -s -X POST -H "$AUTH" \
+  "$SERVER/api/v1/certificates/$CERT_ID/renew" | jq -r '.job_id')
+
+# Check job status transitions
+curl -s -H "$AUTH" "$SERVER/api/v1/jobs/$JOB_ID" | jq '.status'
+```
+
+**Expected:** Job status transitions through pending states as DigiCert validates.
+**PASS if** polling mechanism works and job reaches completion once DigiCert issues the certificate.
+
+### 39.5 Revocation Records Locally
+
+**Test:** Revoke a DigiCert-issued certificate.
+
+```bash
+curl -s -X POST -H "$AUTH" \
+  "$SERVER/api/v1/certificates/$CERT_ID/revoke" \
+  -d '{"reason": "cessationOfOperation"}' | jq '.revoked_at'
+```
+
+**Expected:** Returns `revoked_at` timestamp.
+**PASS if** revocation is recorded locally; operator manages revocation in DigiCert CertCentral dashboard.

+## Part 42: IIS Target Connector (M39)
+
+The IIS target connector (M39) brings Windows infrastructure lifecycle management to certctl. Dual-mode implementation: agent-local PowerShell (primary) for servers with certctl agent, proxy agent WinRM for agentless Windows targets. Full test suite (28 tests) with mock executor pattern for cross-platform testing. Supports PEM-to-PFX conversion, SHA-1 thumbprint computation, and parameterized PowerShell execution.
+
+### Test Suite Coverage
+
+| Layer | Test Count | Focus | Cross-Platform |
+|-------|-----------|-------|-----------------|
+| ValidateConfig | 9 | Field validation, defaults, regex enforcement | Yes |
+| DeployCertificate | 7 | PFX conversion, script execution, error handling | Yes |
+| ValidateDeployment | 5 | Thumbprint verification, binding checks | Mock executor |
+| PFX Conversion | 4 | Certificate chain handling, password generation | Yes |
+| Helpers | 3 | Thumbprint computation, Windows time conversion | Yes |
+| **Total** | **28** | | **26 pass, 2 skip on non-Windows** |
+
+### Automated Tests (qa-smoke-test.sh Part 42)
+
+| # | Test | Assertion |
+|---|------|-----------|
+| 42.1 | IIS connector imports without error | `internal/connector/target/iis/` builds cleanly |
+| 42.2 | ValidateConfig rejects missing hostname | Validation fails when `hostname` absent |
+| 42.3 | ValidateConfig rejects missing site_name | Validation fails when `site_name` absent |
+| 42.4 | ValidateConfig applies defaults | `port` defaults to 443, `ip_address` to "*" |
+| 42.5 | ValidateConfig validates field regex | Rejects field names with invalid characters |
+| 42.6 | PEM-to-PFX conversion succeeds | PKCS#12 bundle created with random password |
+| 42.7 | SHA-1 thumbprint computed correctly | Matches Go crypto/sha1 output, hex-encoded |
+| 42.8 | PowerShell script is parameterized | No unescaped interpolation in generated commands |
+| 42.9 | Mock executor pattern works cross-platform | Tests pass on Linux/macOS via mock executor |
+| 42.10 | DeployCertificate calls Import-PfxCertificate | PowerShell command includes correct cert store |
+| 42.11 | DeployCertificate calls Set-WebBinding | PowerShell command includes site name + thumbprint |
+| 42.12 | ValidateDeployment executes Get-IISSiteBinding | Thumbprint comparison happens post-deployment |
+| 42.13 | Error cases logged and propagated | TLS verify failure, script timeout errors handled |
+| 42.14 | Windows time conversion helpers work | FileTime ↔ time.Time round-trip accurate |
+
+### Manual Tests (Windows Only)
+
+These tests require a real Windows Server 2019+ environment with IIS 10+. Skip on non-Windows platforms.
+
+**42.M1: Agent-Local Deployment — Happy Path**
+
+1. Provision a Windows Server 2019+ VM with IIS installed
+2. Download and install certctl-agent binary for windows-amd64
+3. Register agent with certctl server via heartbeat endpoint
+4. Create IIS target in certctl dashboard:
+   ```json
+   {
+     "hostname": "iis-server.local",
+     "site_name": "Default Web Site",
+     "cert_store": "WebHosting",
+     "port": 443,
+     "sni": true,
+     "ip_address": "*"
+   }
+   ```
+5. Issue a certificate (e.g., via Local CA)
+6. Create deployment job targeting the IIS target
+7. Agent polls work endpoint, executes PowerShell
+8. Verify on IIS: `Get-IISSiteBinding` shows new binding with correct thumbprint
+9. Verify in dashboard: Deployment job shows status=Completed, verified_at timestamp present
+
+**PASS if** certificate deployed to IIS binding with matching thumbprint, deployment job shows Completed with verification success.
+
+**42.M2: Agent-Local Deployment — Renewal**
+
+1. On the same IIS target, trigger renewal of the certificate
+2. Verify old certificate remains bound during renewal (until new one succeeds)
+3. Verify new certificate is imported and bound after deployment
+4. Verify old binding removed or updated in IIS
+
+**PASS if** renewal completes without downtime, old binding replaced with new.
+
+**42.M3: PFX Import to WebHosting Store**
+
+1. Manually generate a test PKCS#12 certificate
+2. Via certctl-agent on Windows, verify PowerShell can import to WebHosting store:
+   ```powershell
+   $pfx = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
+   $pfx.Import([System.IO.File]::ReadAllBytes("C:\temp\test.pfx"), $password, "Exportable")
+   $store = New-Object System.Security.Cryptography.X509Certificates.X509Store("WebHosting", "LocalMachine")
+   $store.Open("MaxAllowed")
+   $store.Add($pfx)
+   ```
+3. Verify certificate appears in IIS Certificate Manager
+
+**PASS if** certificate imports to WebHosting store successfully.
+
+**42.M4: Binding Verification — Thumbprint Match**
+
+1. Deploy a certificate to an IIS site via certctl
+2. Manually run on IIS server:
+   ```powershell
+   Get-IISSiteBinding -Name "Default Web Site" | Select-Object Thumbprint
+   ```
+3. Verify thumbprint matches certificate's SHA-1 hash (as shown in certctl GUI)
+
+**PASS if** thumbprints match exactly (hex-encoded, no colons).
+
+**42.M5: Error Handling — Invalid Site Name**
+
+1. Create IIS target with non-existent site name (e.g., "NonExistentSite")
+2. Trigger deployment
+3. Verify job fails with error message about invalid site
+4. Verify error is logged in agent and audit trail
+
+**PASS if** error handled gracefully, job marked Failed with reason.
+
+**42.M6: Field Validation — Config Injection Attempt**
+
+1. Try to create IIS target with site_name containing PowerShell metacharacters:
+   ```json
+   {
+     "site_name": "Default Web Site'; Get-Process; #"
+   }
+   ```
+2. Verify regex validation rejects this (field validation error, not API error)
+3. Verify no PowerShell execution occurs
+
+**PASS if** injection attempt blocked by field validation.
+
+**42.M7: SNI vs Non-SNI Binding**
+
+1. Create two IIS targets: one with `sni: true`, one with `sni: false`
+2. Deploy certificates to both
+3. Verify Set-WebBinding with `-SslFlags 1` (SNI) for first target
+4. Verify Set-WebBinding without SslFlags (no SNI) for second target
+5. Test TLS connection to both sites, verify SNI-enabled site handles multiple domains correctly
+
+**PASS if** SNI bindings configured correctly per target config.

 # Why certctl?
 
-Certificate management is broken at every scale between "one domain on Let's Encrypt" and "Fortune 500 budget for Venafi."
+Certificate management is broken at every scale between "one domain on Let's Encrypt" and "Fortune 500 budget for Venafi." certctl fills that gap: a self-hosted platform that automates the entire certificate lifecycle, works with any CA, deploys to any server, and keeps private keys on your infrastructure. It's free, source-available, and you own everything.
 
-If you run a personal blog, Certbot works fine. If your company spends $200K/year on Keyfactor, you're covered. But if you're an ops engineer managing 20-500 certificates across NGINX, Apache, HAProxy, and maybe a private CA — the tools available today either don't do enough or cost too much.
+## The Math That Forces the Decision
 
-certctl fills that gap.
+The CA/Browser Forum passed [Ballot SC-081v3](https://cabforum.org/2025/04/11/ballot-sc081v3-introduce-schedule-of-reducing-validity-and-data-reuse-periods/) in April 2025, mandating a phased reduction in TLS certificate lifetimes: **200 days** as of March 2026, **100 days** by March 2027, and **47 days** by March 2029.
 
-## The Problem
+At 47-day lifespans, a team managing 100 certificates is processing **7+ renewals per week**, every week, forever. At 200 certificates, it's two per day. Manual processes, calendar reminders, and certbot cron jobs don't scale to this — a single missed renewal becomes a production outage at 3 AM. Certificate lifecycle automation is no longer optional; the only question is what tool runs it.
 
-The CA/Browser Forum passed [Ballot SC-081v3](https://cabforum.org/2025/04/11/ballot-sc081v3-introduce-schedule-of-reducing-validity-and-data-reuse-periods/) in April 2025, mandating a phased reduction in TLS certificate lifetimes: 200 days as of March 2026, 100 days by March 2027, and 47 days by March 2029. That means every organization needs automated certificate renewal — not eventually, but now.
+## The Landscape Today
 
-The existing options for automation are:
+If you're evaluating your options, here's what you'll find:
 
-- **ACME clients** (Certbot, Lego, CertWarden): Handle issuance and renewal for ACME-compatible CAs, but don't manage deployment to target servers, don't provide inventory visibility, don't support non-ACME CAs, and don't offer audit trails or policy enforcement.
-- **Kubernetes-native** (cert-manager): Works well inside Kubernetes, but if your infrastructure includes bare-metal servers, VMs, or network appliances alongside Kubernetes, you need a separate solution for everything cert-manager can't reach.
-- **Commercial SaaS** (CertKit, Sectigo CLM): Handle more of the lifecycle but are proprietary, cloud-dependent, and priced per certificate — costs scale linearly with your infrastructure.
-- **Enterprise platforms** (Venafi, Keyfactor, AppViewX): Comprehensive but start at $75K/year and require dedicated teams to operate.
+**ACME clients** (certbot, lego, acme.sh) handle issuance and renewal for Let's Encrypt and similar CAs, but they don't deploy to target servers, don't track inventory, don't support private CAs, and give you no audit trail or policy enforcement. You end up writing glue scripts and hoping they don't break.
+
+**Kubernetes-native tools** (cert-manager) work well inside the cluster, but most organizations run mixed infrastructure — NGINX on VMs, HAProxy at the edge, IIS on Windows, maybe an F5. You need a separate solution for everything outside Kubernetes.
+
+**Commercial SaaS platforms** handle more of the lifecycle but are proprietary, cloud-dependent, and priced per certificate. At 100 certs and 20 agents, SaaS pricing runs $3,000-5,000/year and scales linearly. You're paying rent on your own infrastructure's security.
+
+**Enterprise platforms** (Venafi, Keyfactor, AppViewX) are comprehensive but start at $75K/year and require dedicated teams to operate. If you have a 50-server environment, the licensing costs more than the servers.
 
 ## What certctl Does Differently
 
-certctl is a self-hosted certificate lifecycle platform. It handles issuance, renewal, deployment, revocation, discovery, and monitoring — with three design decisions that no other tool at any price point combines:
+certctl handles issuance, renewal, deployment, revocation, discovery, and monitoring — with three design decisions that no other tool at any price point combines:
 
 ### 1. Private Keys Never Leave Your Infrastructure
 
-certctl agents generate private keys locally using ECDSA P-256. The agent creates a CSR and submits it to the control plane. The signed certificate comes back. The private key stays on the agent's filesystem with 0600 permissions.

-This isn't a premium feature — it's the default behavior in the free tier. Most competitors either generate keys server-side (creating a single point of compromise) or gate key isolation behind paid tiers.

 ### 2. CA-Agnostic Issuer Architecture
 
-certctl works with any certificate authority, not just ACME providers:
+certctl works with any certificate authority, not just ACME providers. Seven issuer connectors ship today, all free:
 
-- **ACME** (Let's Encrypt, ZeroSSL, Google Trust Services, Buypass) — HTTP-01 and DNS-01 challenges, DNS-PERSIST-01 for zero-touch renewals, External Account Binding
-- **step-ca** (Smallstep) — native /sign API with JWK provisioner authentication
-- **Local CA** — self-signed or sub-CA mode (chain to your enterprise root CA, e.g. ADCS)
-- **OpenSSL / Custom CA** — delegate signing to any shell script with configurable timeout
-- **EST enrollment** (RFC 7030) — device certificate enrollment for WiFi/802.1X, MDM, and IoT
+- **ACME v2** (Let's Encrypt, ZeroSSL, Google Trust Services, Buypass) — HTTP-01, DNS-01, DNS-PERSIST-01 challenges, External Account Binding, ACME Renewal Information (RFC 9702)
+- **HashiCorp Vault PKI** — `/v1/{mount}/sign/{role}` API, token auth
+- **DigiCert CertCentral** — async order model, OV/EV support
+- **step-ca** (Smallstep) — native /sign API with JWK provisioner auth
+- **Local CA** — self-signed or sub-CA mode (chain to ADCS or any enterprise root)
+- **OpenSSL / Custom CA** — delegate signing to any shell script
+- **EST enrollment** (RFC 7030) — device certs for WiFi/802.1X, MDM, IoT
 
-Every issuer connector implements the same interface. Switching CAs or running multiple CAs in parallel requires zero code changes — just configuration.
+Every connector implements the same interface. Running multiple CAs in parallel — Let's Encrypt for public certs, Vault for internal services, your enterprise CA for legacy systems — is configuration, not code.
 
 ### 3. Post-Deployment Verification
 
-Every other tool in this space stops at "the deployment command succeeded." certctl goes further: after deploying a certificate to a target, the agent connects back to the target's TLS endpoint and verifies the served certificate matches what was deployed, using SHA-256 fingerprint comparison.

-A reload command can exit 0 while the certificate doesn't take effect — wrong virtual host, stale cache, config that validates but doesn't apply. certctl catches this.
+A reload command can exit 0 while the certificate doesn't take effect — wrong virtual host, stale cache, config that validates but doesn't apply. certctl catches this automatically.
+
+## What Else Ships Free
+
+The three differentiators above get the headlines, but the feature surface is wider than most paid platforms:
+
+**10 deployment targets** — NGINX, Apache, HAProxy, Traefik, Caddy, Envoy, IIS (local PowerShell + remote WinRM), Postfix, and Dovecot. All use a pluggable connector model. The control plane never initiates outbound connections — agents poll for work, meaning certctl works behind firewalls, across network zones, and in air-gapped environments.
+
+**Network certificate discovery** — active TLS scanning of CIDR ranges finds certificates you didn't know existed. Agents also scan local filesystems for PEM/DER files. Everything feeds into a triage workflow where you claim, dismiss, or import discovered certs into management.
+
+**Immutable audit trail** — every API call recorded (method, path, actor, body hash, status, latency). Every certificate lifecycle event tracked. Append-only, no update or delete. Mapped to SOC 2, PCI-DSS 4.0, and NIST SP 800-57 compliance frameworks with published evidence guides.
+
+**Policy engine** — 5 rule types (allowed issuers, allowed domains, required metadata, allowed environments, renewal lead time) with violation tracking and severity levels.
+
+**PKI compliance** — DER-encoded X.509 CRL signed by issuing CA, embedded OCSP responder, RFC 5280 revocation with all reason codes, short-lived certificate exemption.
+
+**Prometheus metrics** — `/api/v1/metrics/prometheus` in standard exposition format. Works with Prometheus, Grafana Agent, Datadog Agent, Victoria Metrics.
+
+**MCP server** — 80 tools exposing the entire API surface for AI-assisted certificate management via Claude, Cursor, or any MCP-compatible client. No other certificate platform offers this.
+
+**Full REST API** — 97 OpenAPI 3.1-documented operations. CLI tool with 10 subcommands. Helm chart for Kubernetes deployment. Scheduled certificate digest emails. Certificate export in PEM and PKCS#12. S/MIME support with EKU-aware issuance.
+
+**1,554 tests** — Go backend with race detection, static analysis (golangci-lint), and vulnerability scanning (govulncheck) on every commit. Frontend test suite. CI runs on every push.
 
 ## How certctl Compares
 
-### vs. CertKit
+### vs. ACME Clients
 
-Closest competitor architecturally — agent-based, private key isolation (Keystore), multi-platform. certctl leads on issuer coverage (ACME + step-ca + Local CA + OpenSSL + EST vs. ACME-only), PKI compliance (CRL, OCSP, RFC 5280 revocation, immutable audit trail — all missing from CertKit today), policy engine (5 rule types vs. none), and network discovery (CIDR TLS scanning vs. none). certctl is source-available (BSL 1.1 → Apache 2.0) with no cert limit; CertKit is proprietary SaaS with a 3-cert free tier. Where CertKit leads: more deployment targets today (adds LiteSpeed, IIS, auto-detection), Windows support, Kubernetes, and polished SaaS onboarding.
+ACME clients solve one slice of the problem — issuance and renewal from ACME CAs. certctl replaces the ACME client, adds 6 more CA integrations, deploys the cert to the right server, verifies it's live, tracks it in an inventory, alerts on expiry, logs everything to an audit trail, and enforces policy. If you're currently running certbot behind a cron job and a prayer, certctl replaces all of it.
 
-### vs. KeyTalk
+### vs. Agent-Based SaaS
 
-Commercial (proprietary) PKI platform from a Dutch company — on-prem appliance, cloud, or managed service. Broader cert type coverage (TLS, S/MIME, device auth, VPN) and DigiCert + SCEP integrations. No public documentation on policy engine, API surface, or audit capabilities. No free tier, no public pricing. certctl trades breadth of cert types for full transparency — source-available, public API spec, free community edition with no limits.
+The closest architectural competitors use the same agent model — local key generation, CSR submission, push-based deployment. Where certctl differs: it supports 7 issuer types (not just ACME), provides CRL/OCSP/revocation infrastructure (not just issuance), includes a policy engine and network discovery, and is source-available with no certificate limit. SaaS alternatives are typically proprietary, priced per certificate ($2+/cert/month), and cap their free tiers at 3-5 certificates. certctl is free for any number of certificates, forever.
 
-### vs. Enterprise Platforms (Venafi, Keyfactor)
+### vs. Commercial PKI Platforms
 
-Comprehensive solutions with decades of features — at $75K-$250K+/yr. certctl targets organizations that need 80% of those capabilities at 1% of the cost. The trade-off: no SSO/RBAC yet (coming in certctl Pro), no F5/IIS target connectors yet, no SLA-backed support.
+On-prem or hosted commercial platforms offer broader cert type coverage (VPN certs, device auth, SCEP) and deeper CA integrations. The trade-off: no free tier, opaque pricing (often €13K+/year for 1,500 certs), proprietary codebases, and no public API documentation. certctl trades breadth of exotic cert types for full transparency — source-available code, 97-operation OpenAPI spec, and a free community edition with no artificial limits.
 
-## Getting Started
+### vs. Enterprise Platforms
+
+Venafi and Keyfactor offer decades of features at $75K-$250K+/year. certctl targets organizations that need 80% of those capabilities at a fraction of the cost. What certctl doesn't have yet: SSO/RBAC (coming in certctl Pro), vendor SLA-backed support. What certctl does have that enterprise platforms don't: an MCP server for AI-assisted management, ACME ARI (RFC 9702) for CA-directed renewal timing, and a deployment model that works in 5 minutes instead of 5 months.
+
+## Who Should Look Elsewhere
+
+certctl isn't the right tool for everyone:
+
+- **Single-domain sites** — if you have one certificate on one server, certbot is fine. certctl is designed for managing tens to hundreds of certificates across multiple servers and CAs.
+- **Pure Kubernetes environments** — if every workload runs in-cluster and you're happy with cert-manager, there's no reason to add another tool. certctl shines when your infrastructure extends beyond Kubernetes.
+- **Organizations that need a vendor SLA today** — certctl is source-available software maintained by a small team. If you need contractual uptime guarantees and a support hotline, an enterprise platform is the right choice (for now).
+
+## See It Running
+
+The demo seeds 32 certificates across 7 issuers, 8 agents, 6 deployment targets, and 180 days of realistic history — jobs, audit events, discovery scans, approval workflows — so you can explore every feature immediately.

+// Package digicert implements the issuer.Connector interface for DigiCert CertCentral.
+//
+// DigiCert CertCentral is an enterprise certificate authority offering DV, OV, and EV
+// certificates. Unlike synchronous issuers (Vault, step-ca), DigiCert uses an
+// asynchronous order model: submit an order, receive an order ID, then poll for
+// completion. OV/EV certificates require organization validation which may take hours
+// or days; DV certificates may be issued immediately.
+//
+// This connector maps to certctl's existing job state machine:
+//   - IssueCertificate submits the order; if status is "issued", returns cert immediately.
+//     If status is "pending", returns OrderID with empty CertPEM — the job system polls
+//     via GetOrderStatus.
+//   - GetOrderStatus polls the order; when status becomes "issued", downloads and
+//     parses the PEM bundle.
+//
+// Authentication: API key via X-DC-DEVKEY header.
+//
+// DigiCert CertCentral API used:
+//
+//	POST /order/certificate/{product_type}          - Submit certificate order
+//	GET  /order/certificate/{order_id}              - Check order status
+//	GET  /certificate/{certificate_id}/download/format/pem_all - Download cert bundle
+//	PUT  /certificate/{certificate_id}/revoke       - Revoke certificate
+//	GET  /user/me                                   - Validate API credentials

+// Package sectigo implements the issuer.Connector interface for Sectigo Certificate Manager (SCM).
+//
+// Sectigo Certificate Manager is an enterprise certificate authority offering DV, OV, and EV
+// certificates. Like DigiCert, Sectigo uses an asynchronous order model: submit an enrollment,
+// receive an sslId, then poll for completion. OV/EV certificates require organization validation
+// which may take hours or days; DV certificates may be issued immediately.
+//
+// This connector maps to certctl's existing job state machine:
+//   - IssueCertificate submits the enrollment; if status is "Issued", returns cert immediately.
+//     If status is "Applied" or "Pending", returns OrderID with empty CertPEM — the job system
+//     polls via GetOrderStatus.
+//   - GetOrderStatus polls the order; when status becomes "Issued", downloads and parses the
+//     PEM bundle via the collect endpoint.
+//
+// Authentication: Three custom headers on every request — customerUri, login, password.
+//
+// Sectigo SCM REST API used:
+//
+//	POST /ssl/v1/enroll                - Submit certificate enrollment
+//	GET  /ssl/v1/{sslId}              - Check enrollment status
+//	GET  /ssl/v1/collect/{sslId}/pem  - Download PEM bundle when issued
+//	POST /ssl/v1/revoke/{sslId}       - Revoke certificate
+//	GET  /ssl/v1/types                - List available cert types (used for health check)

+// Package vault implements the issuer.Connector interface for HashiCorp Vault PKI
+// secrets engine.
+//
+// Vault PKI provides a full-featured private CA with certificate signing, revocation,
+// CRL, and OCSP capabilities. This connector uses the Vault HTTP API to sign CSRs
+// via the /v1/{mount}/sign/{role} endpoint, authenticated with a Vault token.
+//
+// Vault issues certificates synchronously (like step-ca), so GetOrderStatus always
+// returns "completed". CRL and OCSP are delegated to Vault's own endpoints.
+//
+// Authentication: Vault token via X-Vault-Token header.
+//
+// Vault API used:
+//
+//	GET  /v1/sys/health                      - Health check
+//	POST /v1/{mount}/sign/{role}             - Sign CSR
+//	POST /v1/{mount}/revoke                  - Revoke certificate
+//	GET  /v1/{mount}/ca/pem                  - Get CA certificate
