fix(seed): repair deployment_targets FK violation crashing fresh demo boot

The Rank 5 cloud-target seed rows in `seed_demo.sql` referenced a
non-existent `ag-server` agent_id. On every fresh-clone
`docker compose -f deploy/docker-compose.yml -f deploy/docker-compose.demo.yml up`
the server crash-looped at the demo-seed step:

  pq: insert or update on table "deployment_targets" violates foreign
  key constraint "deployment_targets_agent_id_fkey"

Origin: commit 9a7e818 ("docs, seed: cloud-target operator runbook +
AWS ACM / Azure KV demo seed rows") added the rows but didn't insert
or rebind to a matching agents row. The `ag-server` ID never existed
in seed_demo.sql or anywhere else.

Fix: bind the two cloud targets to the existing cloud sentinel agents
that were already inserted at lines 78-79 (alongside `cloud-gcp-sm`):

  - tgt-aws-acm-prod  → cloud-aws-sm
  - tgt-azure-kv-prod → cloud-azure-kv

These cloud sentinels were inserted in commit 9a7e818's same family
specifically to back agentless cloud targets — exact semantic match.

Why the existing test didn't catch this:
TestRunDemoSeed_AppliesIdempotently in
internal/repository/postgres/seed_test.go calls the same RunSeed +
RunDemoSeed pair the server uses at boot, so it WOULD have caught the
FK violation. But the test depends on a live PostgreSQL container via
testcontainers-go and is gated under `testing.Short()` → the default
`go test ./... -short` lane that `make verify` runs always skipped it.
The dedicated integration lane that strips `-short` either wasn't run
on commit 9a7e818 or the failure was missed. Promoting the test out
from under `-short` is a separate hardening conversation (CI runs
need docker-in-docker which isn't free); that's out of scope for this
hotfix.

Static FK audit confirms the fix:
  Defined agent IDs (12): ag-{data,edge-01,iis,k8s,lb,mac-dev,
    web-prod,web-staging}-prod, cloud-{aws-sm,azure-kv,gcp-sm},
    server-scanner
  Referenced agent_id values in deployment_targets after fix:
    ag-data-prod, ag-edge-01, ag-iis-prod, ag-k8s-prod, ag-lb-prod,
    ag-web-prod, ag-web-staging, cloud-aws-sm, cloud-azure-kv
  Unresolved: zero.

Acceptance gate (operator-side):
  - docker compose -f deploy/docker-compose.yml \
                   -f deploy/docker-compose.demo.yml up -d --build
    against a fresh clone — server boots clean within 30s, dashboard
    at https://localhost:8443 shows the seeded demo data.

+#     and other source-available licenses, unlike Aikido / Snyk / SonarCloud
+#     free tiers which require OSI-approved licenses).
+#   - SARIF results auto-deduplicate and persist on PRs, so reviewers see

+            > **Install / upgrade:** see the [Quick Start section in the README](https://github.com/certctl-io/certctl/blob/master/README.md#quick-start) for Docker Compose, agent install, Helm, and binary download instructions.
+
+            ## Verifying this release
+
+            Every binary, `checksums.txt`, and container image is signed with Cosign
+            keyless OIDC. Each binary ships with a SPDX-JSON SBOM. Binaries are covered
+            by SLSA Level 3 provenance; container images carry native SLSA L3 provenance
+            and SBOM attestations (docker/build-push-action `provenance: mode=max`,
+            `sbom: true`) in addition to a Cosign signature on the digest.
+
+            **1. Verify SHA-256 checksums:**
 
             ```bash
-            docker pull shankar0123.docker.scarf.sh/certctl-server:${{ steps.version.outputs.VERSION }}
-            docker pull shankar0123.docker.scarf.sh/certctl-agent:${{ steps.version.outputs.VERSION }}
+            sha256sum -c checksums.txt
             ```
 
-            ## Quick Start
+            **2. Verify the Cosign signature on checksums.txt (keyless OIDC):**
 
             ```bash
-            git clone https://github.com/shankar0123/certctl.git
-            cd certctl
-            cp deploy/.env.example deploy/.env
-            docker compose -f deploy/docker-compose.yml up -d
+            cosign verify-blob \
+              --bundle checksums.txt.sigstore.json \
+              --certificate-identity-regexp '^https://github\.com/certctl-io/certctl/\.github/workflows/release\.yml@refs/tags/' \
+              --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
+              checksums.txt
+            ```
+
+            Replace `checksums.txt` with any individual binary name to verify that
+            artefact directly (each binary ships with its own `.sigstore.json`
+            bundle, e.g. `cosign verify-blob --bundle certctl-agent-linux-amd64.sigstore.json …`).
+
+            **3. Verify SLSA Level 3 provenance (binaries):**
+
+            ```bash
+            slsa-verifier verify-artifact \
+              --provenance-path multiple.intoto.jsonl \
+              --source-uri github.com/certctl-io/certctl \
+              --source-tag ${{ steps.version.outputs.VERSION }} \
+              certctl-agent-linux-amd64
+            ```
+
+            **4. Verify container image signature and attestations:**
+
+            ```bash
+            IMAGE=ghcr.io/certctl-io/certctl-server:${{ steps.version.outputs.VERSION }}
+            cosign verify \
+              --certificate-identity-regexp '^https://github\.com/certctl-io/certctl/\.github/workflows/release\.yml@refs/tags/' \
+              --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \

+## v2.0.68 — Image registry path changed ⚠️
+
+> **Image registry path changed.** Starting this release, container images publish to `ghcr.io/certctl-io/certctl-server` and `ghcr.io/certctl-io/certctl-agent`. Existing pulls from `ghcr.io/shankar0123/certctl-{server,agent}:<tag>` continue to work for previously-published tags (the registry never deletes images), but the `:latest` tag at the old path stops moving forward at this release. Update your `docker pull` paths, `docker-compose.yml` `image:` keys, or Helm `image.repository` values to receive future updates. Old `git clone` / `git push` / install-script / API URLs continue to redirect forever — only the container-registry path changed.
+
+This is the only operator-action-required change in v2.0.68. Other changes in this release are cosmetic URL refreshes after the GitHub-org transfer from `shankar0123/certctl` to `certctl-io/certctl` (HTTP redirects mean no other operator action is required) plus an internal contextcheck lint fix in the agent. Full commit list is on the [GitHub release page](https://github.com/certctl-io/certctl/releases/tag/v2.0.68).
+
+---
+
+certctl no longer maintains a hand-edited per-version changelog. Per-release
+notes are auto-generated from commit messages between consecutive tags.
+
+**Where to find what changed in a given release:**
+
+- **[GitHub Releases](https://github.com/certctl-io/certctl/releases)** — every
+  tag has an auto-generated "What's Changed" section pulled from the commits
+  between that tag and the previous one, plus per-release supply-chain
+  verification instructions (Cosign / SLSA / SBOM).
+- **`git log <prev-tag>..<this-tag> --oneline`** — same content, locally.
+
+**Why no hand-edited CHANGELOG.md:**
+
+certctl is solo-developed and pushes directly to master. Maintaining a
+hand-edited CHANGELOG meant the file drifted (entries piled into
+`[unreleased]` and never got promoted to per-version sections when tags were
+cut). A stale CHANGELOG is worse than no CHANGELOG — it signals abandoned
+maintenance to security-conscious operators doing diligence.
+
+The auto-generated release notes work here because commit messages follow a
+descriptive convention: `<area>: <summary>` with a longer body for non-trivial
+changes (see `git log v2.0.50..HEAD` for the established pattern). Anyone
+reading the GitHub Releases page can see exactly what landed in each version
+without depending on the author to manually update a separate file.
+
+**For the historical record:** earlier versions (pre-v2.2.0 and the [2.2.0]
+tag itself) had a hand-edited CHANGELOG. That content is preserved in
+[git history](https://github.com/certctl-io/certctl/blob/v2.2.0/CHANGELOG.md)
+at the v2.2.0 tag.

-# Contributing to certctl
-
-## Architecture Conventions
-
-certctl follows a strict **Handler -> Service -> Repository** layering.
-
-**Handlers** define their own service interfaces (dependency inversion). A handler never imports a concrete service type. This means adding a method to a service requires updating the corresponding handler interface and mock.
-
-**Services** contain business logic. Each service should have at most 5-6 direct dependencies. If a service exceeds ~500 lines or ~6 dependencies, decompose it using the facade/delegation pattern (see `CertificateService` -> `RevocationSvc` + `CAOperationsSvc` for the reference implementation).
-
-**Repositories** are PostgreSQL implementations behind interfaces defined in `internal/repository/interfaces.go`. All SQL is hand-written (no ORM). Use `IF NOT EXISTS` for schema, `ON CONFLICT` for idempotent upserts.
-
-**Connectors** implement pluggable interfaces for issuers (`issuer.Connector`), targets (`target.Connector`), and notifiers (`Notifier`). The `IssuerConnectorAdapter` bridges the connector-layer interface with the service-layer interface to maintain dependency inversion.
-
-### When to Split vs. Extend
-
-Split a component when it exceeds ~500 lines, mixes distinct responsibilities (e.g., CRUD + revocation + CRL generation), or has more than 6 dependencies. Use the facade pattern to avoid breaking handler interfaces.
-
-Extend an existing component when the new functionality is tightly coupled to existing state and adding a new file would create unnecessary indirection.
-
-## Middleware Stack Ordering
-
-The HTTP middleware chain is order-sensitive. The current ordering in `cmd/server/main.go`:
-
-1. `RequestID` - assigns a unique request ID
-2. `NewLogging` - structured slog middleware with request ID propagation
-3. `Recovery` - panic recovery (must be early to catch panics in later middleware)
-4. `NewBodyLimit` - request body size limits via `http.MaxBytesReader` (before auth to reject oversized payloads early)
-5. `NewCORS` - CORS preflight handling (deny-by-default)
-6. `NewAuth` - API key / JWT authentication
-7. `NewAuditLog` - records every API call to the audit trail (after auth so actor is available)
-
-When rate limiting is enabled, `NewRateLimiter` is inserted between `NewBodyLimit` and `NewCORS`.
-
-Contributors adding new middleware must respect this ordering. Body-level middleware goes before auth. Auth-dependent middleware goes after auth.
-
-## Test Patterns and Conventions
-
-### Test File Organization
-
-Every package with production code should have corresponding `_test.go` files in the same package (not a `_test` package). Test helpers belong in `testutil_test.go` within the package.
-
-### Mock Naming Convention
-
-Mock types in test files must be **unexported** (lowercase). The convention:
-
-```go
-// Good - unexported, test-only
-type mockCertificateService struct { ... }
-func newMockCertificateService() *mockCertificateService { ... }
-
-// Bad - exported, leaks into package API
-type MockCertificateService struct { ... }
-```
-
-**Known exception:** Handler test files currently use exported Mock types (e.g., `MockCertificateService`). This is a known deviation being tracked for cleanup.
-
-### Service Layer Tests
-
-Service tests use mock repositories defined in `internal/service/testutil_test.go`. The pattern:
-
-```go
-func TestMyService_Method(t *testing.T) {
-    repo := newMockCertificateRepository()
-    auditRepo := newMockAuditRepository()
-    auditService := NewAuditService(auditRepo)
-    svc := NewMyService(repo, auditService)
-
-    // Set up test data
-    repo.AddCert(&domain.ManagedCertificate{...})
-
-    // Exercise
-    err := svc.DoSomething(context.Background(), "cert-1")
-
-    // Verify
-    if err != nil {
-        t.Fatalf("expected no error, got: %v", err)
-    }
-}
-```
-
-### Handler Layer Tests
-
-Handler tests use `httptest.NewRequest` and `httptest.NewRecorder`. Each handler test file defines its own mock service type implementing the handler's service interface:
-
-```go
-type mockFooService struct {
-    err error
-    // fields for capturing calls and returning data
-}
-
-func TestFooHandler_List(t *testing.T) {
-    mock := &mockFooService{}
-    handler := NewFooHandler(mock)
-    // ...
-}
-```
-
-### Repository Integration Tests
-
-Repository tests in `internal/repository/postgres/` use `testcontainers-go` to spin up a real PostgreSQL 16 container. Key patterns:
-
-- `setupTestDB(t)` creates a shared container for the test run
-- `freshSchema(t, db)` creates an isolated PostgreSQL schema per test (`CREATE SCHEMA test_xxx; SET search_path TO test_xxx`)
-- All migrations are run in each schema so tests start with a clean database
-- Tests are skipped in CI short mode (`testing.Short()`) since they require Docker
-- Run locally with: `go test ./internal/repository/postgres/... -v`
-
-### Fuzz Tests
-
-Fuzz tests use Go's native `testing/fuzz` framework. Located in `*_fuzz_test.go` files. Seed corpora include known adversarial inputs (SQL injection, shell metacharacters, etc.). Run with: `go test -fuzz=FuzzValidateShellCommand ./internal/validation/...`
-
-### CI Coverage Thresholds
-
-The CI pipeline enforces per-layer coverage floors:
-
-| Layer | Threshold | Package Pattern |
-|-------|-----------|-----------------|
-| Service | 60% | `internal/service` |
-| Handler | 60% | `internal/api/handler` |
-| Domain | 40% | `internal/domain` |
-| Middleware | 50% | `internal/api/middleware` |
-
-Adding a new package with tests? Ensure it's included in the `go test` command in `.github/workflows/ci.yml`.
-
-### Race Detection
-
-All tests run with `-race` in CI. Never use shared mutable state without synchronization. The scheduler uses `sync/atomic.Bool` guards; follow the same pattern for any concurrent code.
-
-## Adding New Features
-
-1. **Domain model** in `internal/domain/` - types, constants, validation helpers
-2. **Migration** in `migrations/` - `000N_feature.up.sql` and `.down.sql`, idempotent
-3. **Repository interface** in `internal/repository/interfaces.go`, implementation in `internal/repository/postgres/`
-4. **Service** in `internal/service/` with tests
-5. **Handler** in `internal/api/handler/` defining its own service interface, with tests
-6. **Route registration** via `HandlerRegistry` struct in `internal/api/router/router.go`
-7. **Wire** in `cmd/server/main.go`
-8. **OpenAPI spec** update in `api/openapi.yaml`
-9. **GUI page** in `web/src/pages/` with route in `web/src/main.tsx`
-10. **Seed data** in `migrations/seed_demo.sql` for demo mode
-
-Every backend feature ships with its corresponding GUI surface.
-
-## Environment
-
-- **Go 1.25+**, **PostgreSQL 16+**, **Node.js 22+** (frontend)
-- No ORM - raw `database/sql` + `lib/pq`
-- No web framework - `net/http` stdlib routing
-- Minimal dependencies: 5 direct Go dependencies (see `go.mod`)
-- Frontend: Vite + React 18 + TypeScript + TanStack Query + Recharts + Tailwind CSS
-
-## Documentation That Should Exist But Doesn't Yet
-
-The following are recommended future additions:
-
-- **Architecture diagrams** (Mermaid in `docs/architecture.md` covers some, but data flow diagrams for key workflows like renewal and revocation would help)
-- **Threat model** (formal STRIDE analysis for the control plane, agent communication, and key management boundaries)
-- **Testing philosophy guide** (rationale for mock-vs-real testing decisions, when to use testcontainers vs mocks)
-- **Disaster recovery runbook** (PostgreSQL backup/restore, agent re-registration, CA key rotation procedures)
-- **Upgrade guide** (migration steps between major versions, breaking change policy)
-- **API versioning strategy** (how breaking changes will be handled when /api/v2 is needed)

+Additional Use Grant: You may make use of the Licensed Work, including in
+                      production for your internal business operations and

+                      the Licensed Work as a Commercial Certificate Service.
+
+                      A "Commercial Certificate Service" is a product or
+                      service whose principal value to a third party is the
+                      certificate management functionality of the Licensed
+                      Work — including but not limited to lifecycle
+                      management, discovery, monitoring, alerting, renewal
+                      automation, deployment, and revocation — where the
+                      third party accesses or controls that functionality
+                      and compensation is received for that access or
+                      control.
+
+                      For the avoidance of doubt:
+
+                      (a) you may run the Licensed Work in production to
+                          manage certificates for products or services
+                          that you offer to your customers, where the
+                          principal value of those products or services is

+                          certificate management functionality (for
+                          example, you operate a banking application and
+                          use the Licensed Work internally to manage TLS
+                          certificates for that application);
+
+                      (b) for the purposes of this Additional Use Grant,
+                          "third party" excludes (i) your employees, (ii)
+                          your contractors acting on your behalf, and (iii)

+                          the voting interests of the entity;

+                      (c) the restriction on offering a Commercial
+                          Certificate Service applies regardless of whether

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/) unanimously in April 2025, setting a phased reduction: **200 days** by March 2026, **100 days** by March 2027, and **47 days** by March 2029. Organizations managing dozens or hundreds of certificates can no longer rely on spreadsheets, calendar reminders, or manual renewal workflows. The math doesn't work — at 47-day lifespans, a team managing 100 certificates is processing 7+ renewals per week, every week, forever.

-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.
+For the connector reference (12 issuers, 15 targets, 6 notifiers) see [`docs/reference/connectors/index.md`](docs/reference/connectors/index.md).
 
-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.
-
-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.
-

-
-## What It Does
-
-certctl gives you a single pane of glass for every TLS certificate in your organization:
-
-- **Web dashboard** — full certificate inventory with status, ownership, expiration heatmaps, and bulk operations
-- **REST API** — 93 endpoints under `/api/v1/` + `/.well-known/est/` for complete automation
-- **Agents** — generate private keys locally, discover existing certs on disk, submit CSRs (private keys never leave your servers)
-- **Network scanner** — discovers certificates on TLS endpoints across CIDR ranges without requiring agents
-- **EST server** (RFC 7030) — device and WiFi certificate enrollment via industry-standard protocol
-- **Approval workflows** — require human sign-off on renewals before deployment
-- **Background scheduler** — watches expiration dates and triggers renewals automatically, handling constant rotation at 47-day lifespans without human involvement
-

+## Why certctl
+
+Certificate lifecycle tooling has historically split into two camps. Enterprise platforms charge six-figure annual licenses, take months to deploy, and bill professional-services hours at $250 to $400 per hour to write integration code that should ship with the product. Single-purpose tools handle one slice of the problem and leave the operator to glue the rest together. certctl fills the gap — full lifecycle automation, self-hosted, free, CA-agnostic, target-agnostic. If you're stitching together cron jobs across a fleet, manually renewing certs, or writing custom integration scripts to bridge a commercial CLM platform to your actual infrastructure, certctl replaces all of that.
+
+Built for **platform engineering and DevOps teams** managing 10 to 500+ certificates, **security teams** who need audit trails and policy enforcement, and **small teams without enterprise budgets** who need enterprise-grade automation for a 50-server environment. For the detailed positioning argument and when not to use certctl, see [Why certctl?](docs/getting-started/why-certctl.md).
+
+## What it does
+
+certctl handles the full certificate lifecycle in one self-hosted control plane:
+
+- **Issue and renew** from any CA. Let's Encrypt and any ACME provider, an embedded ACME server you can point cert-manager / certbot / lego at directly, a built-in local CA with sub-CA mode (chains under your enterprise root like ADCS), step-ca, Vault PKI, EJBCA, AWS ACM PCA, Google CAS, DigiCert, Sectigo, GlobalSign, Entrust, plus an OpenSSL / shell-script adapter for anything custom. Twelve native issuer connectors. See the [connector reference](docs/reference/connectors/index.md).
+- **Deploy automatically** to NGINX, Apache, HAProxy, Caddy, Traefik, Envoy, IIS, Windows Cert Store, Java keystore, Kubernetes Secrets, AWS ACM, Azure Key Vault, SSH known-hosts, Postfix + Dovecot, F5 BIG-IP. Fifteen native target connectors. Every deploy goes through atomic-write + ownership-preservation + SHA-256 idempotency + per-target Prometheus counters + pre-deploy snapshot + on-failure rollback. See [`docs/reference/deployment-model.md`](docs/reference/deployment-model.md).
+- **Run as an ACME server** so existing client tooling plugs in directly. RFC 8555 + RFC 9773 ARI, two per-profile auth modes (public-trust-style validation or trust_authenticated for internal PKI), doubly-signed key rollover, revoke-cert on both kid path and jwk path, per-account rate limiting. Cert-manager / certbot / lego all work pointed at it. See [`docs/reference/protocols/acme-server.md`](docs/reference/protocols/acme-server.md).
+- **Run as a SCEP server** for Microsoft Intune-managed phones, ChromeOS devices, network appliances. RFC 8894 native with full PKIMessage wire format, native Intune challenge dispatch with replay protection, per-profile dispatch with separate RA cert per profile. See [`docs/reference/protocols/scep-server.md`](docs/reference/protocols/scep-server.md).
+- **Run as an EST server** for HTTPS-based PKCS#10 enrollment. 802.1X / Wi-Fi authentication, IoT device enrollment, RFC 9266 channel binding. See [`docs/reference/protocols/est.md`](docs/reference/protocols/est.md).
+- **Manage multi-level CA hierarchies** with name constraints, path-length enforcement, and end-to-end RFC 5280 path validation. Root → intermediate → issuing chains, admin-gated CRUD, drain-first retirement. Patterns documented for 4-level boundary CAs, 3-level policy CAs with per-BU `PermittedDNSDomains`, and 2-level internal PKI. See [`docs/reference/intermediate-ca-hierarchy.md`](docs/reference/intermediate-ca-hierarchy.md).
+- **Gate high-stakes issuance** behind two-person-integrity approval. Flag a profile as `RequiresApproval`, the request lands in a queue, a non-requester approves, the scheduler dispatches. See [`docs/operator/approval-workflow.md`](docs/operator/approval-workflow.md).
+- **Discover** existing certs across your fleet via filesystem scanning on agents, network TLS probing across CIDR ranges, and cloud secret manager imports (AWS Secrets Manager, Azure Key Vault, GCP Secret Manager). Triage workflow for claim / dismiss / investigate.
+- **Revoke** with full RFC 5280 reason codes, DER CRL generation per issuer (scheduler-pre-generated and ETag-cached), and an embedded RFC 6960 OCSP responder with dedicated per-issuer responder certs. Single + bulk revocation. See [`docs/reference/protocols/crl-ocsp.md`](docs/reference/protocols/crl-ocsp.md).
+- **Alert** via Slack, Microsoft Teams, PagerDuty, OpsGenie, email, webhooks. Per-policy multi-channel routing matrix with severity tiers and fault-isolating per-channel dispatch. See [`docs/operator/runbooks/expiry-alerts.md`](docs/operator/runbooks/expiry-alerts.md).
+- **Drive the platform from natural language** via the bundled MCP (Model Context Protocol) server. The full REST API is exposed as MCP tools — ask your AI client "show me all expiring certificates", "revoke the VPN cert, key compromised", or "what agents are offline?" and it translates to API calls. Stateless stdio-transport binary at `cmd/mcp-server/`; same auth as the REST API; no extra attack surface. See [`docs/reference/mcp.md`](docs/reference/mcp.md).
+
+## Architecture and security
+
+Go 1.25 control plane with handler → service → repository layering. PostgreSQL 16 backend (35+ tables, idempotent migrations). Pull-only deployment model — the server never initiates outbound connections. Agents poll for work and generate ECDSA P-256 keys locally so private keys never touch the control plane. For network appliances and agentless servers, a proxy agent in the same network zone handles deployment via the target's API (WinRM, iControl REST, SSH/SFTP). See the [Architecture Guide](docs/reference/architecture.md) for full system diagrams.
+
+Security: API key auth enforced by default with SHA-256 hashing and constant-time comparison. CORS deny-by-default. Shell injection prevention on all connector scripts. SSRF protection (reserved IP filtering) on the network scanner. Issuer and target credentials encrypted at rest with AES-256-GCM. HTTPS-only control plane with TLS 1.3 pinned and a fail-closed startup gate that refuses to boot if the TLS bundle is unusable. Every API call recorded to an immutable audit trail with actor attribution, body hash, and latency tracking. CI runs race detection, 11 linters, and vulnerability scanning on every commit. See [`docs/operator/security.md`](docs/operator/security.md) for the operator-facing security posture.

 ## Quick Start
 
-### Docker Pull
+### Docker Compose (recommended)
 
 ```bash
-docker pull shankar0123.docker.scarf.sh/certctl-server
-docker pull shankar0123.docker.scarf.sh/certctl-agent
-```
-
-### Docker Compose (Recommended)
-
-```bash
-git clone https://github.com/shankar0123/certctl.git
+git clone https://github.com/certctl-io/certctl.git
 cd certctl
-docker compose -f deploy/docker-compose.yml up -d --build
+docker compose -f deploy/docker-compose.yml -f deploy/docker-compose.demo.yml up -d --build
 ```
 
-Wait ~30 seconds, then open **http://localhost:8443** in your browser.
+Wait ~30 seconds, then open **https://localhost:8443** in your browser. The shipped demo overlay seeds 32 certificates across 10 issuers, 8 agents, and 180 days of realistic history. The `certctl-tls-init` init container self-signs an ECDSA-P256 cert on first boot — accept the browser warning for the demo, or feed the generated `ca.crt` to your client.
 
-The dashboard comes pre-loaded with 15 demo certificates, 5 agents, policy rules, audit events, and notifications — a realistic snapshot of a certificate inventory so you can explore immediately.
+For a clean install without demo data, drop the `-f deploy/docker-compose.demo.yml` flag and run `docker compose -f deploy/docker-compose.yml up -d --build`. The four compose files (`docker-compose.yml` base, `docker-compose.demo.yml` overlay, `docker-compose.dev.yml` for PgAdmin + debug logging, `docker-compose.test.yml` for integration tests) are documented at [`deploy/ENVIRONMENTS.md`](deploy/ENVIRONMENTS.md).
 
-Verify the API:
 ```bash
-curl http://localhost:8443/health
+curl --cacert $(docker compose -f deploy/docker-compose.yml exec -T certctl-server cat /etc/certctl/tls/ca.crt) https://localhost:8443/health
 # {"status":"healthy"}
-
-curl -s http://localhost:8443/api/v1/certificates | jq '.total'
-# 15
 ```
 
-### Manual Build
+The control plane is HTTPS-only with TLS 1.3 pinned. See [`docs/operator/tls.md`](docs/operator/tls.md) for cert provisioning patterns.
+
+### Agent install (one-liner)
 
 ```bash
-# Prerequisites: Go 1.25+, PostgreSQL 16+
-go mod download
-make build
-
-# Set up database
-export CERTCTL_DATABASE_URL="postgres://certctl:certctl@localhost:5432/certctl?sslmode=disable"
-export CERTCTL_AUTH_TYPE=none
-make migrate-up
-
-# Start server
-./bin/server
-
-# Start agent (separate terminal)
-export CERTCTL_SERVER_URL=http://localhost:8443
-export CERTCTL_API_KEY=change-me-in-production
-export CERTCTL_AGENT_NAME=local-agent
-export CERTCTL_AGENT_ID=agent-local-01
-./bin/agent --agent-id=agent-local-01
+curl -sSL https://raw.githubusercontent.com/certctl-io/certctl/master/install-agent.sh | bash
 ```
 
-## Architecture
+Detects your OS and architecture, downloads the binary, configures systemd (Linux) or launchd (macOS), and starts the agent. See [install-agent.sh](install-agent.sh).
 
-**Control plane** (Go 1.25 net/http) → **PostgreSQL 16** (21 tables, TEXT primary keys) → **Agents** (key generation, CSR submission, cert deployment). Background scheduler runs 6 loops: renewal checks (1h), job processing (30s), agent health (2m), notifications (1m), short-lived cert expiry (30s), network scanning (6h). See [Architecture Guide](docs/architecture.md) for full system diagrams and data flow.
+### Helm chart (Kubernetes)
 
-### Key Design Decisions
+```bash
+helm install certctl deploy/helm/certctl/ \
+  --set server.apiKey=your-api-key \
+  --set postgres.password=your-db-password
+```
 
-- **Private keys isolated from the control plane.** Agents generate ECDSA P-256 keys locally and submit CSRs (public key only). The server signs the CSR and returns the certificate — private keys never touch the control plane. Server-side keygen is available via `CERTCTL_KEYGEN_MODE=server` for demo/development only.
-- **TEXT primary keys, not UUIDs.** IDs are human-readable prefixed strings (`mc-api-prod`, `t-platform`, `o-alice`) so you can identify resource types at a glance in logs and queries.
-- **Handler → Service → Repository layering.** Handlers define their own service interfaces for clean dependency inversion. No global service singletons.
-- **Idempotent migrations.** All schema uses `IF NOT EXISTS` and seed data uses `ON CONFLICT (id) DO NOTHING`, safe for repeated execution.
+Production-ready chart with Server Deployment, PostgreSQL StatefulSet, Agent DaemonSet, health probes, security contexts (non-root, read-only rootfs), and optional Ingress. See [values.yaml](deploy/helm/certctl/values.yaml).
 
-PostgreSQL 16 with 21 tables covering certificates, versions, policies, issuers, targets, agents, jobs, teams, owners, profiles, agent groups, revocations, discovery, network scans, and audit events. See the [Architecture Guide](docs/architecture.md) for the full schema.

-## 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
-
-## API Overview
-
-93 endpoints under `/api/v1/` + `/.well-known/est/`, all returning JSON. List endpoints support pagination, sparse field selection (`?fields=`), sort (`?sort=-notAfter`), time-range filters, and cursor-based pagination. Full request/response schemas in the [OpenAPI 3.1 spec](api/openapi.yaml).

+//     tighten-via-chmod branch).
+//  2. Replacing the real dir with a read-only-from-parent bind: chmod the
+//     grandparent to 0o500 so the chmod syscall on the child fails with
+//     EACCES (the syscall needs write on the path's containing dir for
+//     metadata updates on most unix filesystems — actually no, chmod only
+//     needs ownership, not parent write. So we instead drop the file's
+//     owner via... no — we cannot change ownership without root.)
+//
+// Reaching the chmod-error branch from a non-root test is awkward because
+// chmod only requires ownership (which we always have on t.TempDir()).
+// The cleanest way is to skip on non-root and exercise the branch in CI
+// images that run as root; but our CI runs as non-root. We DO trigger the
+// branch via a different mechanism: replace the path with a SYMLINK to
+// /proc/1/root (or similar) where the eventual stat resolves but chmod
+// fails — but that's brittle and OS-specific.
+//
+// Acceptable closure: document that this branch is exercised by the
+// existing chmod-fails errno path, but the test as written can only assert
+// the wrap-prefix when the branch IS reached. We use a synthetic approach:
+// chmod-tighten a dir we then immediately delete, racing the syscall —
+// not deterministic.
+//
+// Pragmatic resolution: the chmod-error branch is structurally identical
+// to the mkdir-error and stat-error branches (errors.Wrap with a
+// distinct prefix), and is exercised in production via os.Chmod ENOENT
+// or read-only-filesystem failures. We add a unit test that asserts the
+// branch's MESSAGE format by passing through a wrap helper construct.
+// This test instead documents that the branch is structural and any new
+// failure mode (read-only fs, immutable bit, ACLs) inherits the wrap
+// prefix automatically.
+//
+// To still get coverage on the chmod-error branch, we use os.Chmod against
+// a dir whose immediate parent we delete mid-call. This is racy. Instead,
+// we make chmod fail by passing a path that filepath.Clean rewrites to
+// a symlink whose target was just chmod-stripped. Too brittle.
+//
+// CLEANEST APPROACH: rely on the OS's read-only filesystem semantics under
+// /sys (which is RO on linux). os.Chmod on a path under /sys returns EROFS.
+// But /sys is owned by root — stat would succeed only on existing entries,
+// and the function would then attempt chmod, which fails with EROFS (the

+# certctl Docker Compose Environments
+
+This guide walks through every Docker Compose file in the `deploy/` directory. 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, `https://localhost:8443` on your machine reaches the certctl server inside its container (HTTPS-only as of v2.2; the `certctl-tls-init` init container bootstraps a self-signed cert into `deploy/test/certs/`).
+
+---
+
+## 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/certctl-io/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 --cacert ./deploy/test/certs/ca.crt https://localhost:8443/health
+# {"status":"healthy"}
+```
+
+The control plane is HTTPS-only as of v2.2. The `certctl-tls-init` init container bootstraps a self-signed cert into `deploy/test/certs/` on first boot; pin it with `--cacert` (as above) or pass `-k` for one-off smoke tests (never in production).
+
+Open **https://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. Your browser will flag the self-signed cert as untrusted — accept the warning for local evaluation, or import `deploy/test/certs/ca.crt` into your OS trust store to make the warning go away.
+
+### 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.
+
+**Stateful volume — first-boot password binding (U-1).** The same "first boot only" semantics that govern migration scripts also govern `POSTGRES_PASSWORD`. The official `postgres` image runs `initdb` exactly once — when `/var/lib/postgresql/data` is empty — and that pass is the only time `POSTGRES_PASSWORD` is written into `pg_authid`. On every subsequent boot, the postgres container ignores the env var and authenticates against whatever password was baked into the data directory on the original `up`. Editing `POSTGRES_PASSWORD` in `.env` after a successful first boot therefore only updates the **certctl-server** container's `CERTCTL_DATABASE_URL` — postgres still expects the previous password, and the server fails to ping with `pq: password authentication failed for user "certctl"` (SQLSTATE 28P01). The certctl-server container surfaces this case explicitly: when SQLSTATE 28P01 fires at startup, the wrap text in `internal/repository/postgres/db.go::wrapPingError` points operators at the two remediation paths — destructive volume teardown via `docker compose -f deploy/docker-compose.yml down -v && up -d --build`, or non-destructive in-place rotation via `docker compose -f deploy/docker-compose.yml exec postgres psql -U certctl -c "ALTER ROLE certctl PASSWORD '<new>';"` followed by a server restart with the matching `POSTGRES_PASSWORD`. Use the destructive path on the demo / first-time setup; use the non-destructive path on any environment that holds data you want to keep.
+
+#### 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
+```
+
+---
+
+## Demo Overlay
+
+**File:** `docker-compose.demo.yml`
+**When to use:** Demos, screenshots, stakeholder presentations, or any time you want a populated dashboard on first boot.
+
+### What it adds
+
+One env var: `CERTCTL_DEMO_SEED=true` on the `certctl-server` service. The server applies `migrations/seed_demo.sql` at boot via `postgres.RunDemoSeed` AFTER the baseline migrations + `seed.sql` are in place. The demo seed 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.
+
+Pre-U-3 the overlay used to mount `seed_demo.sql` into PostgreSQL's `/docker-entrypoint-initdb.d/` and rely on initdb-time application. That worked only because the production stack also mounted the migrations there, so the schema existed when initdb ran. Once U-3 dropped the production initdb mounts (single source of truth: server runs `RunMigrations` + `RunSeed` at boot), the demo seed could no longer be applied at initdb time — the tables it references wouldn't exist yet. Post-U-3 the overlay is a 27-line override file with no `image:` / `build:` of its own; it MUST be passed alongside the base, or compose errors with `service "certctl-server" has neither an image nor a build context specified`.
+
+### 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 (HTTPS-only as of v2.2; browser will warn on the self-signed cert —
+# accept the warning or trust `deploy/test/certs/ca.crt` in your OS keychain)
+open https://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).

+      # `-run 'VendorEdge_'` (line 379), and no other job ever invokes
+      # `go test -tags integration` with a SCEP selector.
+      #
+      # The result was dead config: SCEP_ENABLED=true triggered the
+      # per-profile validator chain at server boot, but the supporting
+      # fixtures (ra.crt + ra.key + intune_trust_anchor.pem) were never
+      # committed to deploy/test/fixtures/ — only the README documenting
+      # how to regenerate them. Pre-Phase-5 (ci-pipeline-cleanup matrix
+      # collapse) the test stack didn't fully boot the certctl-server in
+      # CI, so the gap was hidden. Once the matrix collapsed and the
+      # collapsed deploy-vendor-e2e job started actually booting the
+      # server, the fail-loud gate at config.go:2069 (CWE-306, empty
+      # CHALLENGE_PASSWORD) fired and blocked CI.

+      # CERTCTL_SCEP_ENABLED is unset → default false → the validator
+      # skips the entire SCEP block. Coherence guard at

+      # rejected at server boot with `Failed to load configuration:

+      # the author miscounted — 4+1+10+1+3+1+2+5+2 = 29). Pre-H-1 the
+      # validator accepted any non-empty string, so the gap was silent. Once

+## Prerequisites
+
+### Required Tools
+
+```bash
+# Verify Kubernetes cluster access
+kubectl cluster-info
+kubectl get nodes
+
+# Install Helm (if not already installed)
+curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash
+helm version
+

+
+### Kubernetes Requirements
+
+- Kubernetes 1.19 or later
+- At least 2GB available memory
+- At least 10GB available storage (for PostgreSQL)
+- Network policies support (optional, for security)
+- Ingress controller (nginx, istio, etc.) - optional
+
+### Create Namespace
+
+```bash
+# Create isolated namespace
+kubectl create namespace certctl
+
+# Set as default namespace
+kubectl config set-context --current --namespace=certctl
+
+# Label for network policies (optional)
+kubectl label namespace certctl certctl-ns=true
+```
+
+## Installation Methods
+
+### Method 1: Minimal Development Setup
+
+Perfect for testing and development:
+
+```bash
+# Install with minimal configuration
+helm install certctl certctl/certctl \
+  --namespace certctl \
+  --set server.auth.apiKey="dev-key-change-in-production" \
+  --set postgresql.auth.password="dev-password-change-in-production"
+
+# Wait for deployment
+kubectl rollout status deployment/certctl-server
+kubectl rollout status statefulset/certctl-postgres
+```
+
+### Method 2: Production HA Setup
+
+For production workloads:
+
+```bash
+# Generate secure credentials
+API_KEY=$(openssl rand -base64 32)
+DB_PASSWORD=$(openssl rand -base64 32)
+
+# Install with HA configuration
+helm install certctl certctl/certctl \
+  --namespace certctl \
+  --values deploy/helm/examples/values-prod-ha.yaml \
+  --set server.auth.apiKey="$API_KEY" \
+  --set postgresql.auth.password="$DB_PASSWORD"
+```
+
+### Method 3: External PostgreSQL
+
+Using managed database service:
+
+```bash
+# Install with external database
+helm install certctl certctl/certctl \
+  --namespace certctl \
+  --values deploy/helm/examples/values-external-db.yaml \
+  --set server.auth.apiKey="$API_KEY" \
+  --set 'server.env.CERTCTL_DATABASE_URL=postgres://user:pass@db.example.com:5432/certctl?sslmode=require'
+```
+
+### Method 4: Using Custom values.yaml
+
+Recommended for GitOps workflows:
+
+```bash
+# Create values file with secrets management
+cat > /tmp/certctl-values.yaml <<EOF
+server:
+  auth:
+    apiKey: "$API_KEY"
+  logging:
+    level: info
+
+postgresql:
+  auth:
+    password: "$DB_PASSWORD"
+  storage:
+    size: 50Gi
+
+agent:
+  enabled: true
+  kind: DaemonSet
+
+ingress:
+  enabled: true
+  className: nginx
+  hosts:
+    - host: certctl.example.com
+      paths:
+        - path: /
+          pathType: Prefix
+EOF
+
+# Install using values file
+helm install certctl certctl/certctl \
+  --namespace certctl \
+  --values /tmp/certctl-values.yaml
+```
+
+## Production Deployment
+
+### Step 1: Prepare Environment
+
+```bash
+# Create namespace
+kubectl create namespace certctl
+cd deploy/helm
+
+# Generate credentials
+API_KEY=$(openssl rand -base64 32)
+DB_PASSWORD=$(openssl rand -base64 32)
+
+echo "API Key: $API_KEY"
+echo "DB Password: $DB_PASSWORD"
+
+# Save credentials in secure location (e.g., 1Password, Vault, AWS Secrets Manager)
+```
+
+### Step 2: Prepare Storage
+
+```bash
+# List available storage classes
+kubectl get storageclass
+
+# If needed, create a high-performance storage class for production
+cat <<EOF | kubectl apply -f -
+apiVersion: storage.k8s.io/v1
+kind: StorageClass
+metadata:
+  name: fast-ssd
+provisioner: ebs.csi.aws.com  # For AWS, adjust for your cloud provider
+parameters:
+  type: gp3
+  iops: "3000"
+  throughput: "125"
+EOF
+```
+
+### Step 3: Set Up TLS with cert-manager
+
+```bash
+# Install cert-manager (if not already installed)
+helm repo add jetstack https://charts.jetstack.io
+helm repo update
+helm install cert-manager jetstack/cert-manager \
+  --namespace cert-manager \
+  --create-namespace \
+  --set installCRDs=true
+
+# Create ClusterIssuer for Let's Encrypt
+kubectl apply -f - <<EOF
+apiVersion: cert-manager.io/v1
+kind: ClusterIssuer
+metadata:
+  name: letsencrypt-prod
+spec:
+  acme:
+    server: https://acme-v02.api.letsencrypt.org/directory
+    email: admin@example.com
+    privateKeySecretRef:
+      name: letsencrypt-prod
+    solvers:
+    - http01:
+        ingress:
+          class: nginx
+EOF
+```
+
+### Step 4: Install Certctl
+
+```bash
+# Install using HA values
+helm install certctl certctl/ \
+  --namespace certctl \
+  --values examples/values-prod-ha.yaml \
+  --set server.auth.apiKey="$API_KEY" \
+  --set postgresql.auth.password="$DB_PASSWORD" \
+  --set ingress.annotations."cert-manager\.io/cluster-issuer"=letsencrypt-prod \
+  --set ingress.hosts[0].host=certctl.example.com
+
+# Verify installation
+kubectl get all -l app.kubernetes.io/instance=certctl
+```
+
+### Step 5: Verify Deployment
+
+```bash
+# Check pod status
+kubectl get pods -l app.kubernetes.io/instance=certctl
+kubectl describe pods -l app.kubernetes.io/instance=certctl
+
+# Check service status
+kubectl get svc -l app.kubernetes.io/instance=certctl
+
+# Check ingress status
+kubectl get ingress
+kubectl describe ingress certctl
+
+# Test API connectivity (HTTPS-only as of v2.2)
+POD=$(kubectl get pods -l app.kubernetes.io/component=server -o jsonpath='{.items[0].metadata.name}')
+kubectl port-forward $POD 8443:8443 &
+# If the chart provisioned a self-signed cert, fetch the CA bundle from the TLS secret first:
+#   kubectl get secret certctl-server-tls -o jsonpath='{.data.ca\.crt}' | base64 -d > /tmp/certctl-ca.crt
+curl --cacert /tmp/certctl-ca.crt -H "Authorization: Bearer $API_KEY" https://localhost:8443/health
+```
+
+### Step 6: Access the Dashboard
+
+```bash
+# Port forward to local machine
+kubectl port-forward svc/certctl-server 8443:8443 &
+
+# Or if using Ingress:
+# Open browser: https://certctl.example.com
+# Login with API key: $API_KEY
+```
+
+## Configuration Examples
+
+### Example 1: ACME (Let's Encrypt)
+
+```bash
+helm install certctl certctl/ \
+  --set server.issuer.acme.enabled=true \
+  --set server.issuer.acme.directoryURL=https://acme-v02.api.letsencrypt.org/directory \
+  --set server.issuer.acme.email=admin@example.com \
+  --set server.issuer.acme.challengeType=http-01
+```
+
+### Example 2: DNS-01 (Wildcard Certs)
+
+Requires DNS scripts ConfigMap:
+
+```bash
+# Create DNS scripts ConfigMap
+kubectl create configmap dns-scripts \
+  --from-file=dns-present.sh=./scripts/dns-present.sh \
+  --from-file=dns-cleanup.sh=./scripts/dns-cleanup.sh
+
+# Install with DNS-01
+helm install certctl certctl/ \
+  --set server.issuer.acme.enabled=true \
+  --set server.issuer.acme.challengeType=dns-01 \
+  --values examples/values-acme-dns01.yaml
+```
+
+### Example 3: AWS RDS Database
+
+```bash
+helm install certctl certctl/ \
+  --set postgresql.enabled=false \
+  --set 'server.env.CERTCTL_DATABASE_URL=postgres://user:password@mydb.c9akciq32.us-east-1.rds.amazonaws.com:5432/certctl?sslmode=require'
+```
+
+### Example 4: Multiple Issuers
+
+```bash
+helm install certctl certctl/ \
+  --set server.issuer.local.enabled=true \
+  --set server.issuer.acme.enabled=true \
+  --set server.issuer.acme.directoryURL=https://acme-v02.api.letsencrypt.org/directory
+```
+
+### Example 5: Email Notifications
+
+```bash
+helm install certctl certctl/ \
+  --set server.smtp.enabled=true \
+  --set server.smtp.host=smtp.example.com \
+  --set server.smtp.port=587 \
+  --set server.smtp.username=alerts@example.com \
+  --set server.smtp.password="$SMTP_PASSWORD" \
+  --set server.smtp.fromAddress=certctl@example.com
+```
+
+## Post-Deployment Setup
+
+### 1. Initial Database Setup
+
+```bash
+# Check database connection
+POD=$(kubectl get pods -l app.kubernetes.io/component=postgres -o jsonpath='{.items[0].metadata.name}')
+
+# Execute psql commands
+kubectl exec -it $POD -- \
+  psql -U certctl -d certctl -c '\dt'
+
+# View database status
+kubectl logs $POD | tail -20
+```
+
+### 2. Create Default Certificates
+
+```bash
+# Port forward to API
+kubectl port-forward svc/certctl-server 8443:8443 &
+
+# Create a test certificate (HTTPS-only as of v2.2 — pin the chart-provisioned CA bundle)
+# kubectl get secret certctl-server-tls -o jsonpath='{.data.ca\.crt}' | base64 -d > /tmp/certctl-ca.crt
+API_KEY="your-api-key"
+curl --cacert /tmp/certctl-ca.crt -X POST https://localhost:8443/api/v1/certificates \
+  -H "Authorization: Bearer $API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "common_name": "test.example.com",
+    "sans": ["test.example.com", "*.example.com"],
+    "owner": "admin@example.com"
+  }'
+```
+
+### 3. Configure Agents
+
+```bash
+# Get agent names
+kubectl get pods -l app.kubernetes.io/component=agent -o wide
+
+# Check agent connectivity
+POD=$(kubectl get pods -l app.kubernetes.io/component=agent -o jsonpath='{.items[0].metadata.name}')
+kubectl logs $POD | grep -i heartbeat
+```
+
+### 4. Set Up HTTPS for Web Dashboard
+
+The Ingress will handle TLS if configured properly:
+
+```bash
+# Verify ingress is ready
+kubectl get ingress
+kubectl describe ingress certctl
+
+# Test HTTPS
+curl https://certctl.example.com/health
+```
+
+## Monitoring and Logging
+
+### 1. View Logs
+
+```bash
+# Server logs
+kubectl logs -l app.kubernetes.io/component=server -f --all-containers=true
+
+# PostgreSQL logs
+kubectl logs -l app.kubernetes.io/component=postgres -f
+
+# Agent logs
+kubectl logs -l app.kubernetes.io/component=agent -f --all-containers=true
+
+# Logs from all components
+kubectl logs -l app.kubernetes.io/instance=certctl -f --all-containers=true
+```
+
+### 2. Install Prometheus Monitoring
+
+```bash
+# Install Prometheus operator (if not already installed)
+helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
+helm repo update
+
+helm install prometheus prometheus-community/kube-prometheus-stack \
+  --namespace monitoring \
+  --create-namespace
+
+# Certctl will automatically expose metrics if monitoring.enabled=true
+helm install certctl certctl/ \
+  --set monitoring.enabled=true \
+  --set monitoring.serviceMonitor.enabled=true
+```
+
+### 3. Set Up Alerts
+
+```bash
+# Create Prometheus alerts
+cat <<EOF | kubectl apply -f -
+apiVersion: monitoring.coreos.com/v1
+kind: PrometheusRule
+metadata:
+  name: certctl-alerts
+spec:
+  groups:
+  - name: certctl
+    interval: 30s
+    rules:
+    - alert: CertctlServerDown
+      expr: up{job="certctl-server"} == 0
+      for: 5m
+      annotations:
+        summary: "Certctl server is down"
+
+    - alert: CertificateExpiringSoon
+      expr: certctl_certificate_expiring_soon > 0
+      for: 1h
+      annotations:

+  --set server.replicas=5
+
+# Scale agents (Deployment kind only)
+helm upgrade certctl certctl/ \
+  --set agent.kind=Deployment \
+  --set agent.replicas=10
+```
+
+### Updating
+
+```bash
+# Update chart version
+helm repo update
+helm upgrade certctl certctl/certctl \
+  --namespace certctl \
+  -f values.yaml
+
+# Verify update
+kubectl rollout status deployment/certctl-server
+kubectl rollout status statefulset/certctl-postgres
+```
+
+### Backup and Restore
+
+```bash
+# Backup PostgreSQL data
+kubectl exec -i $(kubectl get pods -l app.kubernetes.io/component=postgres -o jsonpath='{.items[0].metadata.name}') \
+  pg_dump -U certctl certctl | gzip > certctl-backup.sql.gz
+
+# Restore from backup
+zcat certctl-backup.sql.gz | kubectl exec -i $(kubectl get pods -l app.kubernetes.io/component=postgres -o jsonpath='{.items[0].metadata.name}') \
+  psql -U certctl certctl
+
+# Backup PVC data
+kubectl get pvc
+kubectl exec -i $(kubectl get pods -l app.kubernetes.io/component=postgres -o jsonpath='{.items[0].metadata.name}') \
+  tar czf - /var/lib/postgresql/data | gzip > certctl-data-backup.tar.gz
+```
+
+### Uninstall
+
+```bash
+# Remove Helm release (keeps PVCs by default)
+helm uninstall certctl --namespace certctl
+
+# Delete PVCs if needed
+kubectl delete pvc --all -n certctl
+
+# Delete namespace
+kubectl delete namespace certctl
+```
+
+## Troubleshooting
+
+See [README.md](README.md#troubleshooting) for detailed troubleshooting steps.
+
+Common commands:
+
+```bash
+# Get all resources
+kubectl get all -n certctl
+
+# Describe pod for events
+kubectl describe pod <pod-name> -n certctl
+
+# Stream logs
+kubectl logs -f <pod-name> -n certctl
+
+# Execute commands in pod
+kubectl exec -it <pod-name> -n certctl -- /bin/sh
+
+# Check events
+kubectl get events -n certctl --sort-by='.lastTimestamp'

+### Network Communication
+
+- **Server → PostgreSQL**: Internal cluster DNS (`certctl-postgres:5432`)
+- **Agent → Server**: Internal cluster DNS (`certctl-server:8443`)
+- **External → Server**: Via Ingress or Service (ClusterIP/LoadBalancer/NodePort)
+
+## Security Considerations
+
+### 1. Secrets Management
+
+All sensitive data is stored in Kubernetes Secrets:
+- PostgreSQL credentials
+- API keys
+- SMTP passwords
+- ACME account secrets
+
+**Best Practices:**
+- Use sealed-secrets or external-secrets operator
+- Enable encryption at rest in etcd
+- Rotate secrets regularly
+
+```bash
+# Example: Using sealed-secrets
+kubectl create secret generic certctl-api-key --from-literal=api-key="$(openssl rand -base64 32)" --dry-run=client -o yaml | kubeseal -f - | kubectl apply -f -
+```
+
+### 2. RBAC
+
+The chart creates minimal RBAC by default:
+- ServiceAccount per release
+- ClusterRole (empty, extensible)
+- ClusterRoleBinding
+
+**To restrict further:**
+```yaml
+rbac:
+  create: true
+  # Add specific rules here
+```
+
+### 3. Pod Security
+
+All containers run with:
+- Non-root user (UID 1000)
+- Read-only root filesystem
+- No privilege escalation
+- Dropped capabilities (ALL)
+
+### 4. Network Policies
+
+Restrict pod-to-pod communication:
+
+```yaml
+apiVersion: networking.k8s.io/v1
+kind: NetworkPolicy
+metadata:
+  name: certctl-default-deny
+spec:
+  podSelector:
+    matchLabels:
+      app.kubernetes.io/instance: certctl
+  policyTypes:
+    - Ingress
+    - Egress
+  ingress:
+    - from:
+        - namespaceSelector:
+            matchLabels:
+              name: certctl
+  egress:
+    - to:
+        - namespaceSelector:
+            matchLabels:
+              name: certctl
+    - to:
+        - podSelector: {}
+      ports:
+        - protocol: TCP
+          port: 53  # DNS
+        - protocol: UDP
+          port: 53
+```
+
+### 5. TLS/HTTPS
+
+Enable HTTPS with cert-manager:
+
+```bash
+helm install cert-manager jetstack/cert-manager \
+  --namespace cert-manager \
+  --create-namespace \
+  --set installCRDs=true
+```
+
+Then configure Ingress with TLS.
+
+### 6. API Key Security
+
+For production:
+1. Generate a strong API key: `openssl rand -base64 32`
+2. Store securely (Vault, sealed-secrets, etc.)
+3. Never commit to Git
+4. Rotate periodically
+
+```bash
+# Generate and deploy API key
+NEW_KEY=$(openssl rand -base64 32)
+kubectl patch secret certctl-server -p "{\"data\":{\"api-key\":\"$(echo -n $NEW_KEY | base64)\"}}"
+```
+
+## Troubleshooting
+
+### 1. Pods Not Starting
+
+```bash
+# Check pod status
+kubectl get pods -l app.kubernetes.io/instance=certctl
+kubectl describe pod <pod-name>
+kubectl logs <pod-name>
+```
+
+### 2. Database Connection Issues
+
+```bash
+# Verify PostgreSQL is running
+kubectl get pods -l app.kubernetes.io/component=postgres
+kubectl logs -l app.kubernetes.io/component=postgres
+
+# Test connection from server pod
+kubectl exec -it <server-pod> -- \
+  psql postgres://certctl:password@certctl-postgres:5432/certctl
+```
+
+### 3. Agent Not Connecting
+
+```bash
+# Check agent logs
+kubectl logs -l app.kubernetes.io/component=agent
+
+# Verify server is reachable
+kubectl exec -it <agent-pod> -- \
+  wget -q -O - http://certctl-server:8443/health
+```
+
+### 4. Persistent Data Loss
+
+```bash
+# Check PVC status
+kubectl get pvc
+
+# Verify data is being stored
+kubectl exec -it <postgres-pod> -- \
+  ls -lah /var/lib/postgresql/data/postgres
+```
+
+### 5. Permission Denied Errors
+
+The chart runs containers as non-root (UID 1000). If you see permission errors:
+
+```yaml
+# Temporarily allow root for debugging
+server:
+  securityContext:
+    runAsUser: 0  # NOT FOR PRODUCTION
+```
+
+### 6. Out of Memory
+
+Increase resource limits:
+
+```bash
+helm upgrade certctl certctl/certctl \
+  --set server.resources.limits.memory=1Gi \
+  --set postgresql.resources.limits.memory=2Gi
+```
+
+### 7. Certificate Validation Issues
+
+For self-signed certificates:
+
+```bash
+kubectl exec -it <pod> -- \
+  CERTCTL_TLS_INSECURE_SKIP_VERIFY=true <command>
+```
+
+### Common Issues and Solutions
+
+| Issue | Solution |
+|-------|----------|
+| `ImagePullBackOff` | Update `server.image.repository` to your registry |
+| `CrashLoopBackOff` | Check logs with `kubectl logs <pod>` |
+| `Pending` PVC | Check storage class availability |
+| Connection timeout | Verify network policies and service DNS |
+| High memory usage | Adjust `postgresql.resources.limits` and `server.resources.limits` |

+# certctl Helm Chart
+
+Production-ready Helm chart for deploying [certctl](https://github.com/certctl-io/certctl) on Kubernetes. Wires up the certctl server (Deployment), PostgreSQL (StatefulSet with PVC), and the agent (DaemonSet — one per node) on a private cluster, with health probes, security contexts, and optional Ingress.
+
+## Quick install
+
+```bash
+helm install certctl deploy/helm/certctl/ \
+  --create-namespace --namespace certctl \
+  --set server.auth.apiKey="$(openssl rand -base64 32)" \
+  --set postgresql.auth.password="$(openssl rand -base64 24)"
+```
+
+This brings up:
+
+- `<release>-server` Deployment (HTTPS-only on port 8443; TLS 1.3)
+- `<release>-postgres` StatefulSet (PostgreSQL 16-alpine, 1 replica, 10Gi PVC by default)
+- `<release>-agent` DaemonSet (polls server, generates ECDSA P-256 keys locally)
+- Service objects, optional Ingress, and ServiceAccount with RBAC
+
+See [`values.yaml`](values.yaml) for the full configuration surface — issuer settings, target connectors, scheduler intervals, notifier credentials, and resource requests/limits all live there.
+
+## Operational notes
+
+### Postgres password rotation — read this before changing `postgresql.auth.password`
+
+**The trap.** `postgresql.auth.password` is bound to `pg_authid` exactly once — when the StatefulSet's PVC is provisioned and `initdb` runs. The official `postgres:16-alpine` image only runs `initdb` when `/var/lib/postgresql/data` is empty, so on every subsequent rollout the `POSTGRES_PASSWORD` env var is read into the container but **ignored** by postgres itself. The certctl-server container also picks up the new value (via the database URL helper template), so the two halves diverge: server presents the new password, postgres still expects the old one.
+
+**Symptom.** The certctl-server pod's startup log shows:
+
+```
+failed to ping database: postgres rejected the configured credentials
+(SQLSTATE 28P01 — invalid_password). If you recently rotated POSTGRES_PASSWORD ...
+```
+
+That diagnostic is emitted by `internal/repository/postgres/db.go::wrapPingError` — it points operators at the two remediation paths below.
+
+**Remediation, non-destructive (preferred for any environment with real data):**
+
+```bash
+# 1. Rotate the password in postgres directly
+kubectl -n certctl exec -it <release>-postgres-0 -- \
+  psql -U certctl -c "ALTER ROLE certctl PASSWORD '<new-password>';"
+
+# 2. Update the secret / Helm values to the same value
+helm upgrade <release> deploy/helm/certctl/ \
+  --reuse-values \
+  --set postgresql.auth.password='<new-password>'
+
+# 3. Bounce the certctl-server pod so it re-reads the secret
+kubectl -n certctl rollout restart deployment/<release>-server
+```
+
+**Remediation, destructive (DESTROYS ALL CERTCTL DATA — only acceptable on dev/demo clusters):**
+
+```bash
+helm uninstall <release> -n certctl
+kubectl -n certctl delete pvc -l \
+  app.kubernetes.io/name=certctl,app.kubernetes.io/component=postgres
+helm install <release> deploy/helm/certctl/ \
+  --namespace certctl \
+  --set postgresql.auth.password='<new-password>'
+```
+
+The PVC re-creates empty, `initdb` runs on first boot of the new postgres pod, and `pg_authid` is seeded with the new password.
+
+**Why we don't fix this in the chart.** The env-vs-`pg_authid` divergence is intrinsic to how the upstream `postgres` image bootstraps — `initdb` is run-once-per-empty-data-dir, and there is no upstream-supported way to make subsequent boots re-seed `pg_authid` from `POSTGRES_PASSWORD`. The ergonomic answer is the runtime diagnostic plus this operational note.
+
+**Cross-references.** Same root cause is documented for the docker-compose path in [`docs/quickstart.md`](../../../docs/quickstart.md) (Warning callout after the `cp .env.example .env` block) and in [`deploy/ENVIRONMENTS.md`](../../ENVIRONMENTS.md) (Stateful volume — first-boot password binding section). The runtime diagnostic itself lives in `internal/repository/postgres/db.go::wrapPingError` with regression coverage in `internal/repository/postgres/db_test.go`.
+
+### Server API key rotation
+
+Unlike the postgres password, `server.auth.apiKey` accepts a comma-separated list, so zero-downtime rotation is straightforward:
+
+```bash
+# 1. Add the new key alongside the old
+helm upgrade <release> deploy/helm/certctl/ \
+  --reuse-values \
+  --set server.auth.apiKey='new-key,old-key'
+
+# 2. Roll your agents / clients over to the new key
+
+# 3. Remove the old key
+helm upgrade <release> deploy/helm/certctl/ \
+  --reuse-values \
+  --set server.auth.apiKey='new-key'
+```
+
+### JWT / OIDC via authenticating gateway
+
+certctl's in-process auth surface is intentionally narrow: `server.auth.type=api-key` for production deployments and `server.auth.type=none` for development. There is no in-process JWT, OIDC, mTLS, or SAML middleware. (`server.auth.type=jwt` was accepted pre-G-1 but silently routed every request through the api-key bearer middleware — silent auth downgrade. The chart now fails at `helm install`/`helm upgrade` template time via the `certctl.validateAuthType` helper if you set it. See [`../../../docs/upgrade-to-v2-jwt-removal.md`](../../../docs/upgrade-to-v2-jwt-removal.md) if you previously had this in your values.)
+
+For deployments that need JWT/OIDC, the canonical Kubernetes-flavored shape is to put oauth2-proxy in front of the certctl Service, attach an authenticating Ingress middleware, and run certctl with `server.auth.type=none`:
+
+```bash
+# 1. Install oauth2-proxy (or any OIDC-terminating sidecar) in the same namespace
+helm install oauth2-proxy oauth2-proxy/oauth2-proxy \
+  --namespace certctl \
+  --set config.clientID="$OIDC_CLIENT_ID" \
+  --set config.clientSecret="$OIDC_CLIENT_SECRET" \
+  --set config.cookieSecret="$(openssl rand -base64 32)" \
+  --set config.configFile='|
+    provider = "oidc"
+    oidc_issuer_url = "https://your-issuer/"
+    upstreams = ["http://<release>-server.certctl.svc.cluster.local:8443"]
+    pass_authorization_header = true
+    set_authorization_header = true
+    email_domains = ["*"]
+  '
+
+# 2. Install certctl with type=none (gateway terminates auth)
+helm install certctl deploy/helm/certctl/ \
+  --namespace certctl \
+  --set server.auth.type=none \
+  --set postgresql.auth.password="$(openssl rand -base64 24)"
+
+# 3. Attach an Ingress that routes through oauth2-proxy
+#    (Traefik ForwardAuth, nginx auth_request, Envoy ext_authz, etc.)
+```
+
+Same root pattern works with Pomerium, Authelia, Caddy `forward_auth`, Apache `mod_auth_openidc`, or any service-mesh `ext_authz`. See [`../../../docs/architecture.md`](../../../docs/architecture.md) "Authenticating-gateway pattern" for the full design rationale and [`../../../docs/upgrade-to-v2-jwt-removal.md`](../../../docs/upgrade-to-v2-jwt-removal.md) for the migration walkthrough.
+
+### TLS certificate sourcing
+
+By default the chart provisions a self-signed cert via the same init-container pattern as the docker-compose deploy. For production, supply an operator-managed Secret (cert-manager, internal CA, etc.) — see [`docs/tls.md`](../../../docs/tls.md) for the full provisioning matrix and [`docs/upgrade-to-tls.md`](../../../docs/upgrade-to-tls.md) for upgrade-from-HTTP procedures.
+
+## Disabling embedded postgres
+
+If you have an existing PostgreSQL cluster, disable the embedded one and point at it directly:
+
+```bash
+helm install certctl deploy/helm/certctl/ \
+  --set postgresql.enabled=false \
+  --set server.databaseUrl='postgres://certctl:<pw>@my-pg-host:5432/certctl?sslmode=require'
+```
+
+The volume-trap section above does **not** apply to this configuration — your postgres operator (or cloud DB) handles password rotation, and you control `pg_authid` directly.
+
+## Uninstall
+
+```bash
+helm uninstall <release> -n certctl
+# Optional — also delete the postgres PVC (DESTROYS DATA):
+kubectl -n certctl delete pvc -l \
+  app.kubernetes.io/name=certctl,app.kubernetes.io/component=postgres
+```
+
+By default `helm uninstall` retains the StatefulSet's PVCs, so reinstalling with the same release name preserves the database. If you've changed `postgresql.auth.password` in your values between uninstall and reinstall, you'll hit the trap on the reinstall — apply the non-destructive remediation above, or also delete the PVC.

+
+4. For production with persistent databases and backups:
+   - Use an external PostgreSQL managed service (AWS RDS, Cloud SQL, etc.)
+   - Set postgresql.enabled=false and configure CERTCTL_DATABASE_URL in values

+5. Review security contexts and network policies:
+   - All containers run as non-root
+   - Implement network policies to restrict traffic between components
+   - Consider pod security policies or security standards for your cluster

+# deploy/test/fixtures — integration-test material
+
+This folder holds the fixture material that
+`deploy/docker-compose.test.yml` mounts into the certctl container's
+`/etc/certctl/scep/` for the SCEP-RFC-8894 + Intune integration test
+suite. Test-only material; **do not use in production**.
+
+## Files
+
+| File | Generated by | Purpose |
+| ---- | ------------ | ------- |
+| `intune_trust_anchor.pem` | `deploy/test/scep_intune_e2e_test.go::generateE2EIntuneTrustAnchor` (deterministic ECDSA-P256 from `e2eintuneSeed`) | Mounted at `CERTCTL_SCEP_PROFILE_E2EINTUNE_INTUNE_CONNECTOR_CERT_PATH`. The matching private key is re-derived inside the integration test from the same deterministic seed, so the test can mint valid Intune challenges that the running container accepts. |
+| `ra.crt` + `ra.key` | `setup-trust.sh` at compose boot OR generated once and committed | RA cert + private key the SCEP server uses to decrypt EnvelopedData per RFC 8894 §3.2.2. Mode 0600 enforced on `ra.key` by `preflightSCEPRACertKey`. |
+
+## Regeneration
+
+```sh
+# Trust anchor (deterministic — re-run produces byte-identical PEM):
+cd certctl && go test -tags integration \
+  -run='^TestRegenerateE2EIntuneFixture$' -update-fixture \
+  ./deploy/test/...
+
+# RA pair (one-off — committed):
+openssl ecparam -genkey -name prime256v1 -noout \
+  -out deploy/test/fixtures/ra.key && chmod 600 deploy/test/fixtures/ra.key
+openssl req -new -x509 -key deploy/test/fixtures/ra.key \
+  -days 3650 -subj '/CN=certctl-test-ra' \
+  -out deploy/test/fixtures/ra.crt
+```
+
+## Why these are committed (test-only material)
+
+The integration test runs against the running container and needs to
+mint Intune challenges that the container's trust anchor pool
+recognizes. The deterministic-key approach gives us:
+
+- A static PEM the operator can grep + inspect.
+- A test-side private key derived in-process so we don't commit a
+  raw private key file.
+
+Real production deploys MUST NOT use this trust anchor — the matching
+private key is in the certctl source tree and effectively public.

+// Package integration_test — image-level HEALTHCHECK contract.
+//
+// U-2 (P1, cat-u-healthcheck_protocol_mismatch): pre-U-2 the published
+// server image's Dockerfile HEALTHCHECK called `curl -f http://localhost:
+// 8443/health` against an HTTPS-only listener (HTTPS-Everywhere milestone,
+// v2.2 / tag v2.0.47). Operators outside docker-compose / Helm saw the
+// container reported as `unhealthy` indefinitely. The compose stack
+// overrode this HEALTHCHECK with `--cacert + https://`; the Helm chart
+// uses explicit `httpGet` probes that ignore Docker's HEALTHCHECK; the 5
+// example compose files all override with `curl -sfk https://localhost:
+// 8443/health`. So the observable failure was scoped to bare `docker run`
+// / Docker Swarm / Nomad / ECS users — exactly the "I just pulled the
+// published image" path.
+//
+// This file's tests pin the contract at the binary-image level. The
+// matching CI grep guardrail in .github/workflows/ci.yml catches the
+// regression at the Dockerfile-source level; both layers are needed
+// because someone could replace the HEALTHCHECK line with a sibling
+// broken pattern that the grep doesn't catch (e.g., a TCP-only check
+// against the HTTPS port).
+//
+// Run alongside the rest of the integration suite:
+//
+//	cd deploy/test && go test -tags integration -v -run Healthcheck
+//
+// The tests skip cleanly with t.Skip when docker is not available
+// (CI without docker-in-docker, sandbox environments, etc.) so they
+// don't block local development on machines without docker.
+//
+// Q-1 closure (cat-s3-58ce7e9840be): this file's 5 t.Skip sites are
+// audited and intentional:
+//
+//   - Line 85, 146, 207: `if !dockerAvailable(t)` skips when `docker info`
+//     fails. These are precondition gates; without docker there's nothing
+//     to assert against. Run via: `docker info >/dev/null && go test
+//     -tags integration ./deploy/test/...`.
+//   - Line 209-210: `if testing.Short()` keeps the ~45s runtime probe
+//     off the default `go test ./... -short` path. Run via: omit -short.
+//   - Line 212: hard t.Skip for the runtime probe contract — image-spec
+//     contract above (TestPublishedServerImage_HealthcheckSpecUsesHTTPS)
+//     covers the audit-flagged regression at the Dockerfile-source level.
+//     Re-enable once the integration harness provisions a sidecar postgres
+//     for image-level smoke; the existing skip message names this

+# EST RFC 7030 hardening master bundle Phase 10.1 — libest sidecar.
+#
+# Multi-stage build of Cisco's libest reference client, used as the
+# canonical RFC 7030 client for the certctl integration test suite.
+#
+# Source: https://github.com/cisco/libest (the upstream reference
+# implementation; latest tag is r3.2.0 — verified via
+# https://api.github.com/repos/cisco/libest/tags 2026-04-30. The
+# protocol surface we exercise is stable RFC 7030). We build from
+# source rather than pulling a published image because no official
+# Cisco image exists on Docker Hub + reproducible offline-friendly
+# builds need a pinned ref.
+#
+# Note: an earlier draft of this Dockerfile (commit 15da1f4) pinned
+# LIBEST_REF=v3.2.0-2 — that ref does not exist upstream (cisco/libest
+# tags do NOT use the `v` prefix and there is no `-2` patch suffix).
+# The build silently broke until ci-pipeline-cleanup Phase 8's Docker
+# build smoke surfaced it.
+#
+# The builder stage compiles libest + its OpenSSL dependency; the
+# runtime stage carries only the compiled `estclient` binary +
+# `openssl` + `bash` so the integration test (which docker-execs into
+# the container) has a small, predictable surface.
+#
+# Build (from repo root):
+#   docker build -f deploy/test/libest/Dockerfile -t certctl/libest:test .
+#
+# CI uses `docker compose --profile est-e2e build libest-client` to
+# orchestrate the build alongside the rest of the test stack.
+
+ARG LIBEST_REF=r3.2.0
+
+# Why bullseye-slim and NOT bookworm-slim:
+#
+# libest r3.2.0 (last upstream commit 2020-07-06) was authored
+# against OpenSSL 1.1.x and binutils ≤ 2.35. It does NOT build on
+# OpenSSL 3.0 / binutils 2.36+ for three independent reasons surfaced
+# by the ci-pipeline-cleanup Phase 8 Docker build smoke step:
+#
+#   1. `FIPS_mode` / `FIPS_mode_set` — removed in OpenSSL 3.0;
+#      libest calls them in 5 places (est_client.c lines 3179, 3590,
+#      3676; est_server.c line 3336; estclient.c line 1283).
+#      Even libest `main` branch (last update 2024-07-12) still uses
+#      these without OpenSSL-version guards.
+#   2. `e_ctx_ssl_exdata_index` declared without `extern` in
+#      est_locl.h:593 — multiple-definition error under the binutils
+#      2.36+ default `-fno-common`. Fixed on libest main but not
+#      backported to r3.2.0.
+#   3. `ossl_dump_ssl_errors` duplicate symbol between libest and
+#      example/client/utils.c — same `-fno-common` shape.
+#
+# debian:bullseye-slim ships:
+#   - OpenSSL 1.1.1n — FIPS_mode/FIPS_mode_set present as expected
+#   - binutils 2.35.2 — pre-`-fno-common` default; tolerates the
+#     multiple-def shape libest was written under
+#
+# All three build errors vanish simultaneously. The earlier draft of
+# this Dockerfile (commit 15da1f4 + 320ef73) used bookworm-slim and
+# silently broke the build; ci-pipeline-cleanup Phase 8's Docker
+# build smoke surfaced it.
+#
+# Bullseye support timeline: regular updates until 2026-08, LTS
+# until 2028-08. The libest sidecar is a hermetic test-only fixture
+# (not exposed to attackers, not shipped in production), so the
+# OpenSSL 1.1.1 EOL (2023-09) is acceptable here. Production
+# certctl images stay on bookworm-slim with OpenSSL 3.0.

+# est_locl.h:593 declares `int e_ctx_ssl_exdata_index;` without
+# `extern`, so under GCC 10+ every libest .c file gets its own copy

+#
+#   -fcommon                          → restore GCC 9 / pre-2020

+#
+# Separately, `ossl_dump_ssl_errors` is *defined* (not just
+# declared) in BOTH src/est/est_ossl_util.c:310 (inside libest)
+# AND example/client/util/utils.c:33 (which estclient links).
+# This is a real-function-level duplicate; -fcommon doesn't apply.
+#
+#   -Wl,--allow-multiple-definition   → restore the pre-strict ld
+#                                       behavior that tolerates

+# Both flags restore the build contract libest 3.2.0 was authored
+# under — they're the documented migration path for projects that
+# relied on the GCC 9 / older binutils default. Not a band-aid;
+# this is the canonical way to build libest 3.2.0 on a modern
+# toolchain.
+#
+# bullseye-slim's GCC is 10.2 (already enforces -fno-common); the
+# next-older default-fcommon GCC is 9.x in debian:buster, which is
+# LTS-EOL since June 2024. Restoring the flag explicitly is cleaner
+# than downgrading the base again.
+#
+# CRITICAL: pass CFLAGS + LDFLAGS at configure-time ONLY. Do NOT also
+# pass them on the `make` command line.
+#
+# Why: libest's configure.ac (lines 193-195) unconditionally appends
+# the bundled safec stub paths to the user's CFLAGS/LDFLAGS/LIBS:
+#
+#   CFLAGS="$CFLAGS -Wall -I$safecdir/include"
+#   LDFLAGS="$LDFLAGS -L$safecdir/lib"
+#   LIBS="$LIBS -lsafe_lib"
+#
+# The merged values get baked into the generated Makefile as
+# @CFLAGS@/@LDFLAGS@/@LIBS@ substitutions, so every link command —
+# notably estclient's — gets `-L/src/safe_c_stub/lib -lsafe_lib`.
+#
+# Per automake's variable-precedence rules, a command-line
+# `make LDFLAGS=...` OVERRIDES the `LDFLAGS = @LDFLAGS@` line in
+# the Makefile. Pass-through at make-time wipes the safec stub's
+# `-L` path; estclient then fails to link with
+# `cannot find -lsafe_lib` even though `safe_c_stub/lib/libsafe_lib.a`
+# built fine. Configure-time alone is sufficient — configure writes
