feat(M47): add Kubernetes Secrets target + AWS ACM PCA issuer connectors

Implement both M47 connectors with full cross-layer wiring:

Kubernetes Secrets target: DNS-1123 validation, kubernetes.io/tls Secret
create-or-update, chain concatenation, serial number validation, Helm
RBAC gating. 18 tests.

AWS ACM Private CA issuer: synchronous issuance (like Vault), ARN regex
validation, RFC 5280 revocation reason mapping, CA cert retrieval,
factory + env var seeding. 23 tests.

Cross-cutting: domain types, service validation, config, factory, agent
dispatch, frontend (TargetsPage, issuerTypes), OpenAPI, seed data, Helm
chart, connectors docs, README. Testing docs (testing-guide, qa-test-guide,
qa_test.go) with Parts thematically integrated near related connectors.

 ## 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, 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** — plug in any certificate authority: Let's Encrypt via ACME, Smallstep step-ca, HashiCorp Vault PKI, DigiCert CertCentral, your enterprise ADCS via sub-CA mode, or any custom CA through a shell script adapter. Run multiple issuers simultaneously for different certificate types.
 
-It's **target-agnostic**. Agents deploy certificates to NGINX, Apache, HAProxy, Traefik, Caddy, Envoy, Postfix, Dovecot, and IIS (local PowerShell or remote WinRM) — all using the same pluggable connector model. 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.

Each section explains what the environment does, when to use it, every service and environment variable, and the commands to run it. If you've never used Docker before, start with the [Prerequisites](#prerequisites) section. If you're experienced, skip to the environment you need.

+8. [Common Operations](#common-operations)
+
+---
+
+## Prerequisites
+
+You need two things: **Docker** (the container runtime) and **Docker Compose** (an orchestration tool that ships with Docker Desktop).
+
+On macOS:
+```bash
+brew install --cask docker
+```
+
+On Linux (Ubuntu/Debian):
+```bash
+curl -fsSL https://get.docker.com | sh
+sudo usermod -aG docker $USER
+# Log out and back in for group changes to take effect
+```
+
+Verify the install:
+```bash
+docker --version        # Docker Engine 24+ recommended
+docker compose version  # Docker Compose v2+ required (note: no hyphen)
+```
+
+**What Docker actually does:** Docker packages an application and all its dependencies (OS libraries, runtimes, config files) into an isolated unit called a container. When you run `docker compose up`, Docker reads a YAML file that describes multiple containers, creates a private network between them, and starts everything in the right order. Each container sees only its own filesystem and network unless you explicitly share volumes or ports.
+
+**Why this matters for certctl:** Instead of installing PostgreSQL, building Go binaries, configuring the agent, and wiring everything together by hand, one command gives you the complete platform. Each compose file targets a different use case.
+
+---
+
+## How Docker Compose Works
+
+A compose file defines **services** (containers), **networks** (how they talk to each other), and **volumes** (persistent storage). The key concepts:
+
+**Services** are named containers. `certctl-server` is the API and web dashboard. `postgres` is the database. `certctl-agent` polls the server for certificate work.
+
+**Depends_on + healthchecks** control startup order. The server won't start until PostgreSQL reports healthy. The agent won't start until the server reports healthy. This prevents connection errors during boot.
+
+**Volumes** persist data across restarts. `postgres_data` keeps your database between `docker compose down` and `docker compose up`. Adding `-v` to `down` deletes volumes for a clean slate.
+
+**Overlay files** let you layer changes. Running `docker compose -f base.yml -f overlay.yml up` merges both files. The overlay can add services, change environment variables, or mount extra volumes without editing the base.
+
+**Port mapping** (`"8443:8443"`) maps host port (left) to container port (right). After startup, `http://localhost:8443` on your machine reaches the certctl server inside its container.
+
+---
+
+## Base Environment
+
+**File:** `docker-compose.yml`
+**When to use:** Production deployments, first-time setup, or any time you want a clean dashboard with the onboarding wizard.
+
+### What it runs
+
+Three services on a private bridge network:
+
+| Service | Image | Purpose | Ports |
+|---------|-------|---------|-------|
+| `postgres` | `postgres:16-alpine` | Database. Stores certificates, agents, jobs, audit trail, policies, discovery results. | 5432 |
+| `certctl-server` | Built from `Dockerfile` | API server + web dashboard + background scheduler. | 8443 |
+| `certctl-agent` | Built from `Dockerfile.agent` | Polls server for work, generates keys, deploys certificates, discovers existing certs. | none |
+
+### Starting it
+
+```bash
+git clone https://github.com/shankar0123/certctl.git
+cd certctl
+docker compose -f deploy/docker-compose.yml up -d --build
+```
+
+`--build` compiles the Go server and agent from source, including the React frontend. Without it, Docker may reuse a stale image from a previous build.
+
+`-d` runs in detached mode (background). Omit it to see logs in your terminal.
+
+Wait about 30 seconds, then verify:
+```bash
+docker compose -f deploy/docker-compose.yml ps
+# All three services should show "Up (healthy)"
+
+curl http://localhost:8443/health
+# {"status":"healthy"}
+```
+
+Open **http://localhost:8443** in your browser. You'll see the onboarding wizard guiding you through: connecting a CA, deploying an agent, and adding your first certificate.
+
+### Service-by-service walkthrough
+
+#### PostgreSQL
+
+```yaml
+postgres:
+  image: postgres:16-alpine
+  environment:
+    POSTGRES_DB: certctl
+    POSTGRES_USER: certctl
+    POSTGRES_PASSWORD: ${POSTGRES_PASSWORD:-certctl}
+```
+
+Alpine-based PostgreSQL 16. The `${POSTGRES_PASSWORD:-certctl}` syntax means: use the `POSTGRES_PASSWORD` environment variable from your shell if set, otherwise default to `certctl`. For production, create a `.env` file:
+
+```bash
+echo 'POSTGRES_PASSWORD=your-secure-password-here' > deploy/.env
+```
+
+The `volumes` section mounts 10 migration files into PostgreSQL's init directory (`/docker-entrypoint-initdb.d/`). PostgreSQL runs these SQL files in alphabetical order on first boot only. They create the schema (tables, indexes, constraints) and seed the base data (default issuer, default policy). If the `postgres_data` volume already exists with an initialized database, these scripts are skipped entirely.
+
+**Expert note:** The numbered prefix pattern (`001_`, `002_`, ..., `020_`) ensures deterministic execution order. All migrations use `IF NOT EXISTS` and `ON CONFLICT DO NOTHING` for idempotency, so re-running them against an existing database is safe.
+
+#### certctl Server
+
+```yaml
+certctl-server:
+  depends_on:
+    postgres:
+      condition: service_healthy
+  environment:
+    CERTCTL_DATABASE_URL: postgres://certctl:${POSTGRES_PASSWORD:-certctl}@postgres:5432/certctl?sslmode=disable
+    CERTCTL_SERVER_HOST: 0.0.0.0
+    CERTCTL_SERVER_PORT: 8443
+    CERTCTL_LOG_LEVEL: info
+    CERTCTL_AUTH_TYPE: none
+    CERTCTL_KEYGEN_MODE: server
+    CERTCTL_NETWORK_SCAN_ENABLED: "true"
+    CERTCTL_CONFIG_ENCRYPTION_KEY: ${CERTCTL_CONFIG_ENCRYPTION_KEY:-change-me-32-char-encryption-key}
+```
+
+The server is the control plane. It serves the REST API, the React dashboard, runs 7 background scheduler loops (renewal, job processing, health checks, notifications, short-lived cert expiry, network scanning, digest emails), and manages the issuer/target registry.
+
+Key environment variables explained:
+
+- `CERTCTL_DATABASE_URL` references the `postgres` service by hostname. Docker's internal DNS resolves `postgres` to the container's IP on the bridge network. `sslmode=disable` is appropriate because traffic stays on the private Docker network.
+- `CERTCTL_AUTH_TYPE: none` disables API key authentication so you can explore immediately. For production, set `api-key` and configure `CERTCTL_AUTH_SECRET`.
+- `CERTCTL_KEYGEN_MODE: server` means the server generates private keys. This is convenient for demos but insecure for production. In production, set `agent` so keys are generated on agent machines and never transmitted.
+- `CERTCTL_CONFIG_ENCRYPTION_KEY` enables AES-256-GCM encryption for issuer and target configurations stored in the database (credentials, API keys). Without this, the dynamic configuration GUI (adding issuers/targets from the dashboard) won't encrypt sensitive fields. For production, generate a strong random key.
+- `CERTCTL_NETWORK_SCAN_ENABLED` activates the scheduler loop that probes TLS endpoints on your network to discover certificates you might not be managing.
+
+**Expert note:** The healthcheck hits `GET /health` every 10 seconds with 5 retries. The `depends_on: condition: service_healthy` on the agent means Docker holds agent startup until this check passes. Resource limits (`cpus: '1.0'`, `memory: 512M`) prevent the server from consuming unbounded resources in shared environments.
+
+#### certctl Agent
+
+```yaml
+certctl-agent:
+  depends_on:
+    certctl-server:
+      condition: service_healthy
+  environment:
+    CERTCTL_SERVER_URL: http://certctl-server:8443
+    CERTCTL_API_KEY: ${CERTCTL_API_KEY:-change-me-in-production}
+    CERTCTL_AGENT_NAME: docker-agent
+    CERTCTL_LOG_LEVEL: info
+    CERTCTL_DISCOVERY_DIRS: /var/lib/certctl/keys
+  volumes:
+    - agent_keys:/var/lib/certctl/keys
+```
+
+The agent is a lightweight Go binary that polls the server for pending work (certificate deployments, CSR generation requests), executes that work locally, and reports results back. It also scans configured directories for existing certificates (filesystem discovery).
+
+- `CERTCTL_SERVER_URL` uses the Docker internal hostname `certctl-server`. This resolves inside the Docker network only.
+- `CERTCTL_DISCOVERY_DIRS` tells the agent which directories to scan for existing certificates. The agent walks these directories recursively, parses PEM and DER files, and reports findings to the server for triage.
+- The `agent_keys` volume persists private keys generated by the agent across container restarts. Without this volume, keys would be lost when the container stops.
+
+**Expert note:** The agent's healthcheck uses `pgrep` because the agent doesn't expose an HTTP endpoint. The `restart: unless-stopped` policy means Docker automatically restarts the agent on crashes but respects manual `docker compose stop` commands.
+
+### Stopping and cleaning up
+
+```bash
+# Stop containers but keep data
+docker compose -f deploy/docker-compose.yml down
+
+# Stop and delete all data (database, keys, volumes)
+docker compose -f deploy/docker-compose.yml down -v
+```

+**When to use:** Demos, screenshots, stakeholder presentations, or any time you want a populated dashboard on first boot.
+
+### What it adds
+
+One line: mounts `seed_demo.sql` into PostgreSQL's init directory. This 667-line SQL file inserts 180 days of simulated operational history: teams, owners, certificates across multiple issuers, agents on different platforms, jobs with realistic timestamps, discovery scan results, audit events, policies, and profiles.
+
+### Starting it
+
+```bash
+docker compose -f deploy/docker-compose.yml -f deploy/docker-compose.demo.yml up -d --build
+```
+
+The `-f` flags are ordered: base first, overlay second. Docker merges them. The demo overlay adds the seed_demo.sql volume mount to the `postgres` service defined in the base file.
+
+### What you see
+
+The dashboard shows pre-populated charts: expiration heatmap with upcoming renewals, status distribution across Active/Expiring/Expired/Failed states, 30-day job trends, and issuance rates. The sidebar pages (Certificates, Agents, Discovery, Jobs, etc.) all have data to explore.
+
+### Resetting demo data
+
+```bash
+docker compose -f deploy/docker-compose.yml -f deploy/docker-compose.demo.yml down -v
+docker compose -f deploy/docker-compose.yml -f deploy/docker-compose.demo.yml up -d --build
+```
+
+The `down -v` deletes the `postgres_data` volume. On next boot, PostgreSQL re-runs all init scripts including the demo seed, giving you a clean starting point.
+
+**Expert note:** The demo overlay is a pure data layer, not a configuration change. The server, agent, and their environment variables remain identical to the base. This means any behavior you see in the demo is exactly what the base environment produces once you populate data through normal operations.
+
+---
+
+## Development Overlay
+
+**File:** `docker-compose.dev.yml`
+**When to use:** When you're contributing to certctl and need debug logging, database inspection, or a debugger attached to the server process.
+
+### What it adds
+
+| Addition | Purpose |
+|----------|---------|
+| Debug-level logging on server and agent | See every HTTP request, scheduler tick, and connector operation |
+| PgAdmin on port 5050 | Visual database browser for inspecting tables, running queries |
+| Delve debugger port 40000 | Attach a Go debugger to the running server process |
+
+### Starting it
+
+```bash
+docker compose -f deploy/docker-compose.yml -f deploy/docker-compose.dev.yml up --build
+```
+
+Omit `-d` during development so you see logs streaming in your terminal.
+
+### Using PgAdmin
+
+Open **http://localhost:5050** in your browser. PgAdmin is pre-configured in desktop mode (no login required). To connect to the certctl database:
+
+1. Right-click "Servers" in the left panel, choose "Register" > "Server"
+2. Name: `certctl`
+3. Connection tab: Host = `postgres`, Port = `5432`, Username = `certctl`, Password = `certctl` (or whatever you set in `.env`)
+
+From there you can browse all 19 tables, inspect certificate records, view audit events, check the scheduler's job queue, and run arbitrary SQL.
+
+### Using the Delve debugger
+
+Port 40000 is exposed for remote debugging. To use it, you'd need to modify the Dockerfile to build with debug symbols and start the server under Delve:
+
+```bash
+# In Dockerfile, replace the CMD with:
+CMD ["dlv", "--listen=:40000", "--headless=true", "--api-version=2", "exec", "/app/server"]
+```
+
+Then attach from your IDE (VS Code, GoLand) using remote debug configuration pointing to `localhost:40000`.
+
+### Hot reload
+
+The dev overlay includes commented-out volume mounts for source code directories. Uncomment them and install [air](https://github.com/cosmtrek/air) to get automatic recompilation on file changes:
+
+```bash
+go install github.com/cosmtrek/air@latest
+```
+
+**Expert note:** The `builds: context: ..` in the dev overlay overrides the base service's image reference, forcing a local build from the repository root. This means changes to your Go source code are compiled fresh on each `docker compose up --build`.
+
+---
+
+## Test Environment
+
+**File:** `docker-compose.test.yml`
+**When to use:** Integration testing against real CA backends. This is a standalone environment (not an overlay) with 7 containers on a static-IP subnet.
+
+### What it runs
+
+| Service | IP | Purpose |
+|---------|----|---------|
+| `postgres` | 10.30.50.2 | Database (clean, no demo data) |
+| `pebble-challtestsrv` | 10.30.50.3 | DNS/HTTP challenge test server for Pebble |
+| `pebble` | 10.30.50.4 | ACME test server (simulates Let's Encrypt) |
+| `step-ca` | 10.30.50.5 | Private CA (Smallstep, JWK provisioner) |
+| `certctl-server` | 10.30.50.6 | Control plane with all issuers configured |
+| `nginx` | 10.30.50.7 | TLS target server for deployment testing |
+| `certctl-agent` | 10.30.50.8 | Agent with NGINX volume + discovery |
+
+### Why static IPs?
+
+Pebble (the ACME test server) validates HTTP-01 challenges by connecting to the challenge URL. It resolves domain names via `pebble-challtestsrv`, which is configured to return `10.30.50.6` (the certctl server) for all lookups. Without static IPs, container IPs would be assigned randomly on each boot, breaking the challenge validation chain.
+
+The `/24` subnet (10.30.50.0/24) provides 254 usable addresses, far more than needed but standard practice for test networks.
+
+### Starting it
+
+```bash
+docker compose -f deploy/docker-compose.test.yml up --build
+```
+
+Wait for all health checks to pass (about 60 seconds for step-ca's first-run bootstrap). Then:
+
+```bash
+# Dashboard with auth enabled
+open http://localhost:8443
+# API key: test-key-2026
+
+# NGINX serving a self-signed placeholder
+curl -k https://localhost:8444
+```
+
+### What's different from the base
+
+The test environment is configured for production-like behavior:
+
+- **API key auth enabled** (`CERTCTL_AUTH_TYPE: api-key`, `CERTCTL_AUTH_SECRET: test-key-2026`). Every API request needs `Authorization: Bearer test-key-2026`.
+- **Agent-side key generation** (`CERTCTL_KEYGEN_MODE: agent`). The agent generates ECDSA P-256 keys locally and submits only the CSR to the server. Private keys never leave the agent container.
+- **Three real issuers configured:**
+  - **Local CA** (self-signed) for instant issuance testing
+  - **ACME via Pebble** for Let's Encrypt-compatible flow testing (HTTP-01 challenges validated through the challenge test server)
+  - **step-ca** for private CA testing with JWK provisioner authentication
+- **EST server enabled** (`CERTCTL_EST_ENABLED: "true"`) for RFC 7030 enrollment testing
+- **Post-deployment verification enabled** (`CERTCTL_VERIFY_DEPLOYMENT: "true"`) so the agent probes NGINX after deploying a cert and confirms the TLS fingerprint matches
+- **Dynamic config encryption enabled** (`CERTCTL_CONFIG_ENCRYPTION_KEY`) so issuer/target configs added through the GUI are encrypted at rest
+- **TLS trust bootstrapping:** The server runs a `setup-trust.sh` entrypoint that fetches Pebble's root CA from its management API and copies step-ca's root cert from a shared volume, then runs `update-ca-certificates` before starting the server binary. This is necessary because both CAs use self-signed roots that aren't in Alpine's default trust store.
+
+### Running the Go integration tests
+
+The test environment is designed to support the Go integration test suite at `deploy/test/integration_test.go`:
+
+```bash
+# Start the environment
+docker compose -f deploy/docker-compose.test.yml up --build -d
+
+# Wait for health checks
+sleep 30
+
+# Run integration tests (from repo root)
+go test -tags integration -v ./deploy/test/...
+```
+
+The integration tests exercise 12 phases: health, agent heartbeat, Local CA issuance, ACME issuance, renewal, step-ca issuance, revocation + CRL + OCSP, EST enrollment, S/MIME issuance, discovery, network scan, and deployment verification. PostgreSQL port 5432 is exposed so the test binary can query the database directly for assertions.
+
+See [docs/test-env.md](../docs/test-env.md) for the full walkthrough and manual QA procedures.
+
+### Stopping and cleaning up
+
+```bash
+# Stop but keep data (volumes persist)
+docker compose -f deploy/docker-compose.test.yml down
+
+# Full reset (delete step-ca bootstrap, database, agent keys, NGINX certs)
+docker compose -f deploy/docker-compose.test.yml down -v
+```
+
+**Expert note:** The step-ca container auto-bootstraps on first run: generates a root CA, creates a JWK provisioner named "admin" with password "password123", and writes everything to the `stepca_data` volume. Subsequent starts reuse this volume. If you `down -v`, the next boot generates a new root CA, which means all previously issued step-ca certs become untrusted.

+## Common Operations
+
+### Viewing logs
+
+```bash
+# All services
+docker compose -f deploy/docker-compose.yml logs -f
+
+# Single service
+docker compose -f deploy/docker-compose.yml logs -f certctl-server
+
+# Last 100 lines
+docker compose -f deploy/docker-compose.yml logs --tail 100 certctl-server
+```
+
+### Rebuilding after code changes
+
+```bash
+docker compose -f deploy/docker-compose.yml up -d --build
+```
+
+Docker only rebuilds images that have changed source files. The `--build` flag is essential after editing Go code or frontend files.
+
+### Connecting to the database directly
+
+```bash
+docker exec -it certctl-postgres psql -U certctl -d certctl
+```
+
+Useful queries:
+```sql
+-- Certificate inventory
+SELECT id, common_name, status, expires_at FROM managed_certificates ORDER BY expires_at;
+
+-- Recent jobs
+SELECT id, type, status, certificate_id, created_at FROM jobs ORDER BY created_at DESC LIMIT 20;
+
+-- Audit trail
+SELECT event_type, actor, resource_id, created_at FROM audit_events ORDER BY created_at DESC LIMIT 20;
+
+-- Issuer configurations (encrypted_config is AES-256-GCM)
+SELECT id, type, source, enabled, test_status FROM issuers;
+```
+
+### Checking container resource usage
+
+```bash
+docker stats --no-stream
+```
+
+### Upgrading
+
+```bash
+git pull
+docker compose -f deploy/docker-compose.yml up -d --build
+```
+
+Migrations are idempotent (`IF NOT EXISTS`), so upgrading to a version with new schema changes is safe. PostgreSQL only runs init scripts on first boot of a fresh volume, so new migrations in an upgrade require running them manually:
+
+```bash
+docker exec -i certctl-postgres psql -U certctl -d certctl < migrations/000011_new_feature.up.sql
+```
+
+Or, for a clean upgrade: `down -v` and `up --build` (loses existing data).

 ### 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, Traefik, Caddy, Envoy, Postfix, Dovecot, IIS fully implemented; F5 BIG-IP interface stub only) 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.

 After deployment, agents can perform **post-deployment TLS verification**: the agent probes the live TLS endpoint using `crypto/tls.DialWithDialer` and compares the SHA-256 fingerprint of the served certificate against what was deployed. Results are reported via `POST /api/v1/jobs/{id}/verify` and stored on the job record. Verification is best-effort — failures don't block or rollback deployments.

 **Graceful degradation:** If your CA doesn't support ARI (returns 404 from the ARI endpoint), certctl automatically falls back to the traditional threshold-based renewal. No configuration change needed — the fallback is transparent. Errors from the CA are logged as warnings and don't block the renewal process.
 
+### Shorter Certificate Validity (45-Day and 6-Day Certs)
+
+The industry is moving toward shorter certificate lifetimes. The CA/Browser Forum's SC-081v3 ballot mandates a phased reduction: 200-day max (March 2026), 100-day max (March 2027), and 47-day max (March 2029). Let's Encrypt has already begun reducing default validity to 45 days, and offers 6-day "shortlived" certificates via ACME profile selection.

+certctl handles shorter-lived certificates correctly out of the box:
+
+- **45-day certs** with the default 31-day renewal window trigger renewal at day 14 — at roughly 1/3 of the cert's lifetime.
+- **6-day "shortlived" certs** are always within the renewal window. ARI (RFC 9773) is the expected renewal path for these — the CA directs timing. Short-lived certs also skip CRL/OCSP since expiry is sufficient revocation (per profile TTL < 1 hour exemption).
+- **ACME profile selection** lets you request specific certificate profiles from your CA. Set `CERTCTL_ACME_PROFILE=shortlived` to get 6-day certificates from Let's Encrypt, or `CERTCTL_ACME_PROFILE=tlsserver` for standard TLS certificates.

+**Deployment modes:**
+- **In-cluster (default):** Agent runs as a Pod with a ServiceAccount. Authentication via auto-mounted token. Requires RBAC (`secrets.get`, `secrets.create`, `secrets.update`, `secrets.list`) — see Helm chart.
+- **Out-of-cluster:** Agent runs outside the cluster with `kubeconfig_path` pointing to a kubeconfig file. Useful for proxy agent pattern.
+
+**Secret format:** Standard `kubernetes.io/tls` with `tls.crt` (cert + chain PEM) and `tls.key` (private key PEM). Managed labels (`app.kubernetes.io/managed-by: certctl`) and annotations (`certctl.io/deployed-at`, `certctl.io/certificate-id`) are applied automatically.
+
+**Validation:** After deployment, the connector reads the Secret back and compares the certificate serial number to verify successful deployment.

+# QA Test Suite Guide (`qa_test.go`)
+
+> **Audience:** Anyone running release QA for certctl — whether you're a first-time contributor or the maintainer cutting a release tag.
+>
+> **Companion to:** `docs/testing-guide.md` (the *what* to test). This document explains the *how* — the automated test file, what it covers, what it skips, and how to fill the gaps manually.
+
+---
+
+## What Is This File?
+
+`deploy/test/qa_test.go` is a single Go test file (~1700 lines) that automates as much of `docs/testing-guide.md` as possible against a running certctl Docker Compose demo stack. It replaces the legacy `qa-smoke-test.sh` bash script.
+
+It covers **all 54 Parts** of the testing guide:
+
+- **~164 automated subtests** — API calls, database queries, source file checks, performance benchmarks
+- **11 skipped Parts** — with documented reasons (external CAs, Windows, browser-only, etc.)
+- **Remaining ~282 manual tests** — GUI flows, scheduler timing, Docker log inspection — must be done by a human following `docs/testing-guide.md`
+
+## Architecture
+
+```
+┌────────────────────────┐     ┌──────────────────────────┐
+│  qa_test.go            │────▶│  certctl demo stack      │
+│  (//go:build qa)       │     │  docker-compose.yml +    │
+│                        │     │  docker-compose.demo.yml │
+│  TestQA(t *testing.T)  │     │                          │

+│   ├─ ...               │     └──────────────────────────┘
+│   └─ Part52_HelmChart  │
+└────────────────────────┘
+```
+
+Key design choices:
+
+- **Build tag:** `//go:build qa` — never runs during `go test ./...` or CI. Only runs when explicitly requested.
+- **Package:** `integration_test` — same package as `integration_test.go` (which uses `//go:build integration` for the test stack). They coexist but never run together.
+- **Zero internal imports:** Uses only stdlib + `lib/pq` (from `go.mod`). All API interactions are plain HTTP. All JSON is decoded into lightweight local structs (`qaCert`, `qaJob`, etc.) — not the internal domain types.
+- **Self-cleaning:** Tests that create data use `t.Cleanup()` to delete it afterward. The seed data is not modified.
+
+## Prerequisites
+
+1. **Docker Compose demo stack running:**
+   ```bash
+   cd deploy
+   docker compose -f docker-compose.yml -f docker-compose.demo.yml up --build -d
+   ```
+   Wait ~15 seconds for health checks to pass.
+
+2. **Go 1.22+** installed (the project uses Go 1.25 in `go.mod`, but 1.22+ works for running tests).
+
+3. **PostgreSQL port exposed** — the demo stack exposes port 5432 for database verification tests (table counts, schema checks).
+
+4. **Repository checkout** — source file verification tests (`fileExists`, `fileContains`) read files relative to `qaRepoDir` (default: `../..` from `deploy/test/`).
+

+
+**Totals:** ~164 automated subtests, 11 fully skipped Parts, ~282 manual tests remaining.
+
+## Test Categories
+
+The automated tests fall into four categories:
+
+### 1. API Integration Tests (majority)
+Make real HTTP requests to the running server and verify status codes, response structure, and JSON field values. Examples:
+- `POST /api/v1/certificates` with valid payload → 201
+- `GET /api/v1/certificates?status=Active` → all returned certs have `status: "Active"`
+- `DELETE /api/v1/certificates/mc-qa-full` → 204
+
+### 2. Database Verification Tests
+Connect directly to PostgreSQL and verify schema state:
+- Table count ≥ 19 (from migrations 000001–000010)
+- Useful for catching migration regressions
+
+### 3. Source File Verification Tests
+Read files from the repo checkout and verify structure:
+- Domain types exist in `internal/domain/connector.go` (e.g., `TargetTypeEnvoy`)
+- Connector implementations exist (e.g., `internal/connector/target/envoy/envoy.go`)
+- Documentation contains expected content (all issuer/target types listed)
+- No stale RFC 9702 references (replaced by RFC 9773)
+
+### 4. Performance Spot Checks
+Timed API requests with threshold assertions:
+- `GET /api/v1/certificates?per_page=15` < 200ms
+- `GET /api/v1/stats/summary` < 500ms
+- `GET /api/v1/metrics/prometheus` < 300ms
+
+## What This Test Does NOT Cover
+
+These gaps must be filled by manual testing per `docs/testing-guide.md`:
+
+### External CA Integrations (Parts 10–13)
+- **Sub-CA mode** — requires CA cert+key files on disk
+- **ACME ARI** — requires a CA that supports RFC 9773 Renewal Information
+- **Vault PKI** — requires a running HashiCorp Vault instance
+- **DigiCert / Sectigo / Google CAS** — requires sandbox API credentials
+
+### Browser/GUI Testing (Parts 35–37, 50)
+- Dashboard chart rendering (Recharts)
+- Onboarding wizard step-by-step flow
+- Issuer catalog card layout and create wizard
+- Bulk operations UI (multi-select, progress bars)
+- Discovery triage workflow
+
+### Real Deployment Testing (Parts 15–17)
+- NGINX/Apache/HAProxy file write + reload
+- Traefik/Caddy file provider or API reload
+- IIS PowerShell/WinRM (requires Windows)
+- F5 BIG-IP iControl REST (requires appliance or mock)
+- SSH agentless deployment (requires target host)
+
+### Agent Binary Behavior (Parts 18, 28–29)
+- Agent-side ECDSA key generation and CSR submission
+- Agent filesystem discovery scan
+- CLI tool (`certctl-cli`) — all 10 subcommands
+- MCP server (`mcp-server`) — stdio transport
+
+### Timing-Dependent Tests (Parts 33–34)
+- Background scheduler loop execution (renewal, jobs, health, notifications, digest, network scan)
+- Structured logging format verification (requires Docker log parsing)
+
+## How This Relates to `integration_test.go`
+
+Both files live in `deploy/test/` in the same Go package (`integration_test`):
+
+| | `qa_test.go` | `integration_test.go` |
+|---|---|---|
+| **Build tag** | `//go:build qa` | `//go:build integration` |
+| **Target stack** | Demo (`docker-compose.yml` + `docker-compose.demo.yml`) | Test (`docker-compose.test.yml`) |
+| **Port** | 8443 | Different (test stack config) |
+| **Seed data** | `seed_demo.sql` (32 certs, 8 agents, realistic history) | Minimal (created by tests) |
+| **CA backends** | Local CA only (demo mode) | Pebble ACME, step-ca, NGINX |
+| **Purpose** | Release QA — broad coverage, spot checks | Functional — end-to-end issuance, renewal, revocation against real CAs |
+| **Run frequency** | Before each release tag | CI on every PR |
+
+They are complementary. Integration tests prove the machinery works. QA tests prove the product works at release quality.

+## Troubleshooting
+
+### "Server unreachable" on startup
+The test pings `GET /health` before running anything. If this fails:
+```bash
+# Check if the stack is running
+docker compose -f docker-compose.yml -f docker-compose.demo.yml ps
+
+# Check server logs
+docker compose -f docker-compose.yml -f docker-compose.demo.yml logs certctl-server
+
+# Check if the port is exposed
+curl -s http://localhost:8443/health
+```
+
+### "connect to QA DB" failure
+The database tests connect directly to PostgreSQL. Ensure port 5432 is exposed:
+```bash
+docker compose -f docker-compose.yml -f docker-compose.demo.yml port postgres 5432
+```
+
+### Performance tests flaking
+The performance thresholds (200ms, 300ms, 500ms) assume a local Docker stack. On slow CI runners or remote Docker hosts, increase the thresholds or skip Part 39:
+```bash
+go test -tags qa -v -run 'TestQA/Part(?!39)' ./...
+```
+
+### Source file checks failing
+The `fileExists` and `fileContains` helpers read from `CERTCTL_QA_REPO_DIR` (default `../..`). If running from a non-standard location:
+```bash
+CERTCTL_QA_REPO_DIR=/absolute/path/to/certctl go test -tags qa -v ./...
+```
+
+## Adding New Tests
+
+When a new feature ships:
+
+1. **Add a Part section** in `qa_test.go` following the numbering in `docs/testing-guide.md`
+2. **API tests**: use `c.get()`, `c.post()`, `c.bodyStr()`, `c.getJSON()`, `c.timedGet()`
+3. **Source checks**: use `fileExists(t, "relative/path")` and `fileContains(t, "path", "substring")`
+4. **DB checks**: use `openQADB(t)` and `db.queryInt(t, "SELECT ...")`
+5. **Cleanup**: always use `t.Cleanup()` for data created during tests
+6. **Skip if external**: use `t.Skip("Requires X — manual test")` with a clear reason
+
+## Version History

+### Docker Compose Environments
+
+The `deploy/` directory contains four compose files for different use cases:
+
+| File | Purpose | How to run |
+|------|---------|------------|
+| `docker-compose.yml` | **Base platform.** PostgreSQL + certctl server + agent. Clean dashboard with onboarding wizard — use this for production or first-time setup. | `docker compose -f deploy/docker-compose.yml up --build` |
+| `docker-compose.demo.yml` | **Demo data override.** Layers 180 days of realistic seed data (15 certs, 5 agents, multiple issuers) onto the base. Dashboard charts and tables look populated on first boot. | `docker compose -f deploy/docker-compose.yml -f deploy/docker-compose.demo.yml up --build` |
+| `docker-compose.dev.yml` | **Development override.** Adds PgAdmin (port 5050), debug-level logging, and a Delve debugger port (40000) for the server. | `docker compose -f deploy/docker-compose.yml -f deploy/docker-compose.dev.yml up --build` |
+| `docker-compose.test.yml` | **Integration test environment.** 7 containers on a static-IP subnet: PostgreSQL, certctl server+agent, step-ca, Pebble ACME server, challenge test server, and NGINX. Runs the full issuance→deployment→verification flow against real CA backends. Standalone — does not combine with the base file. | `docker compose -f deploy/docker-compose.test.yml up --build` |
+
+Override files are layered onto the base with multiple `-f` flags. The test environment is self-contained and runs independently. To reset any environment's data, add `down -v` to remove volumes.
+
+For a deep dive into every service, environment variable, and networking decision, see the [Docker Compose Environments Guide](../deploy/ENVIRONMENTS.md).

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. Commercial PKI Platforms
 
-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.

+// AWS ACM Private CA (ACM PCA) provides a fully managed private certificate authority
+// with certificate signing, revocation, and CRL capabilities. This connector uses the
+// AWS ACM PCA API to issue and manage certificates.
+//
+// This connector issues certificates synchronously: the IssueCertificate call returns
+// the issued certificate immediately. GetOrderStatus always returns "completed" since
+// issuance is synchronous. CRL and OCSP operations are delegated to AWS PCA's own
+// endpoints.
+//
+// Authentication: AWS credentials via the standard credential chain (environment variables,
+// IAM role, instance profile, or SSO). Configuration specifies the CA ARN, region, and
+// optional signing algorithm and validity days.
+//
+// AWS ACM PCA API used (abstracted via ACMPCAClient interface):
+//
+//	IssueCertificate  - Issue a certificate from a CSR
+//	GetCertificate    - Retrieve the issued certificate
+//	RevokeCertificate - Revoke a certificate
+//	GetCACertificate  - Get the CA certificate chain
