fix(gui): wire create modal onSuccess callbacks and fix short-lived profile UX

- All 5 create modals (Profiles, Teams, Owners, Policies, Agent Groups)
  had no-op onSuccess callbacks — API call fired but modal never closed
  and list never refreshed. Wired invalidateQueries + setShowCreate.
- Removed silent try/catch error swallowing so API errors surface in UI.
- Profile create: auto-set TTL to 300s when short-lived checkbox enabled
  with TTL >= 3600, added validation hint and warning text.

 # certctl — Self-Hosted Certificate Lifecycle Platform
 
-TLS certificate lifespans are shrinking. 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. Manual certificate management is no longer viable at any scale.

Track every certificate in your organization, automatically renew them before they expire, and deploy them to your servers without touching a terminal. Private keys never leave your infrastructure.
+TLS certificate lifespans are shrinking fast. 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.

+certctl is a self-hosted platform that automates the entire certificate lifecycle — from issuance through renewal to deployment — with zero human intervention. It works with any certificate authority, deploys to any server, and keeps private keys on your infrastructure where they belong.

+## Why certctl Exists
+
+Certificate lifecycle tooling today falls into two camps: expensive enterprise platforms (Venafi, Keyfactor, Sectigo) that cost six figures and take months to deploy, or single-purpose tools (cert-manager, certbot) that handle one slice of the problem. If you run a mixed infrastructure — some NGINX, some Apache, a few HAProxy nodes, maybe an F5 — and you need to manage certificates from multiple CAs, there's nothing self-hosted that covers the full lifecycle without vendor lock-in.
+
+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.
+
+For a detailed comparison with CertKit, KeyTalk, and enterprise platforms (Venafi, Keyfactor), see [Why certctl?](docs/why-certctl.md)
 
 ## What It Does
 
-certctl gives you a single pane of glass for every TLS certificate in your organization. The **web dashboard** shows your full certificate inventory — what's healthy, what's expiring, what's already expired, and who owns each one. The **REST API** (91 endpoints under `/api/v1/`) lets you automate everything. **Agents** deployed on your infrastructure generate private keys locally, discover existing certificates on disk, and submit CSRs — private keys never leave your servers. The **network scanner** discovers certificates on TLS endpoints across your infrastructure without requiring agents. The background scheduler watches expiration dates and triggers renewals automatically — when certificate lifespans drop to 47 days, certctl handles the constant rotation without human involvement.

+## Supported Integrations
+
+### Certificate Issuers
+| Issuer | Status | Type |
+|--------|--------|------|
+| Local CA (self-signed + sub-CA) | Implemented | `GenericCA` |
+| ACME v2 (Let's Encrypt, Sectigo) | Implemented (HTTP-01 + DNS-01 + DNS-PERSIST-01) | `ACME` |
+| ACME EAB (ZeroSSL, Google Trust) | Implemented (auto-fetch EAB from ZeroSSL) | `ACME` |

 - **Handler → Service → Repository layering.** Handlers define their own service interfaces for clean dependency inversion. No global service singletons.

 ## Roadmap
 
-### V1 (v1.0.0 released)
-All nine development milestones (M1–M9) are complete. The backend covers the full certificate lifecycle: Local CA and ACME v2 issuers, NGINX/Apache/HAProxy/F5/IIS target connectors, threshold-based expiration alerting, agent-side ECDSA P-256 key generation, API auth with rate limiting, and a React dashboard with 19 pages wired to the real API. The CI pipeline runs build, vet, test with coverage gates (service layer 30%+, handler layer 50%+), frontend type checking, Vitest test suite, and Vite production build on every push. Docker images are published to GitHub Container Registry on every version tag via the release workflow.
+### V1 (v1.0.0)

 ## Overview
 
 Certctl is a certificate management platform with a **decoupled control-plane and agent architecture**. The control plane orchestrates certificate issuance and renewal, while agents deployed across your infrastructure handle key generation, certificate deployment, and local validation — private keys never leave the infrastructure they were generated on.

+### EST Server (RFC 7030)
+
+The EST (Enrollment over Secure Transport) server provides an industry-standard enrollment interface for devices that need certificates without using the REST API. It runs under `/.well-known/est/` per RFC 7030 and supports four operations: CA certificate distribution (`/cacerts`), initial enrollment (`/simpleenroll`), re-enrollment (`/simplereenroll`), and CSR attributes (`/csrattrs`).
+
+**Architecture:** EST is a handler-level protocol that delegates certificate issuance to an existing `IssuerConnector`. This means EST is not a new issuer — it's a new *interface* to the existing issuance infrastructure. The `ESTService` bridges the `ESTHandler` to whichever issuer connector is configured via `CERTCTL_EST_ISSUER_ID`.
+
+```
+Client (WiFi AP, MDM, IoT)
+    │
+    ▼
+ESTHandler (handler layer)
+    │  CSR parsing, PKCS#7 response encoding
+    ▼
+ESTService (service layer)
+    │  CSR validation, CN/SAN extraction, audit recording
+    ▼
+IssuerConnector (connector layer via IssuerConnectorAdapter)
+    │  Certificate signing (Local CA, step-ca, etc.)
+    ▼
+Signed certificate returned as PKCS#7 certs-only
+```
+
+**Wire format:** EST uses PKCS#7 (RFC 2315) certs-only degenerate SignedData for certificate responses and base64-encoded DER for CSR requests. The handler includes a hand-rolled ASN.1 PKCS#7 builder — no external PKCS#7 dependency. The CSR reader accepts both base64-encoded DER (standard EST wire format) and PEM-encoded PKCS#10 (convenience for debugging).
+
+**Interface:** The `ESTHandler` defines an `ESTService` interface (dependency inversion, same pattern as all other handlers):
+
+```go
+type ESTService interface {
+    GetCACerts(ctx context.Context) (string, error)
+    SimpleEnroll(ctx context.Context, csrPEM string) (*domain.ESTEnrollResult, error)
+    SimpleReEnroll(ctx context.Context, csrPEM string) (*domain.ESTEnrollResult, error)
+    GetCSRAttrs(ctx context.Context) ([]byte, error)
+}
+```
+
+**Issuer connector extension:** EST required adding `GetCACertPEM(ctx) (string, error)` to the issuer connector interface so the `/cacerts` endpoint can serve the CA chain. The Local CA connector returns its CA certificate PEM; ACME, step-ca, and OpenSSL connectors return errors (they don't expose a static CA chain — their chains are per-issuance).
+
+**Audit:** Every EST enrollment is recorded in the audit trail with `protocol: "EST"`, the CN, SANs, issuer ID, serial number, and optional profile ID.

 ### API Audit Log
 
-In addition to application-level audit events, certctl records every HTTP API call via middleware.

Health and readiness probes are excluded to avoid noise.
+In addition to application-level audit events, certctl records every HTTP API call via middleware. The audit middleware captures method, URL path (excluding query parameters — see security note below), actor (extracted from auth context), SHA-256 request body hash (truncated to 16 characters), response status code, and request latency. Health and readiness probes are excluded to avoid noise.
+
+**Security: Query Parameter Exclusion** — The audit middleware intentionally records `r.URL.Path` only (not `r.URL.String()` or `r.RequestURI`). Query strings may contain cursor tokens, API keys passed as params, or other sensitive filter values. Since the audit trail is append-only with no deletion capability, any sensitive data recorded would persist permanently.
 
 Audit recording is async (via goroutine) so it never blocks the HTTP response. If audit persistence fails, the error is logged immediately — the API call still succeeds. The middleware sits after the auth middleware in the stack so the actor identity is available from context.
 
+### Input Validation and SSRF Protection
+
+All shell-facing inputs (connector scripts, domain names, ACME tokens) are validated through `internal/validation/command.go` before reaching shell execution. `ValidateShellCommand()` denies all shell metacharacters. `ValidateDomainName()` enforces RFC 1123. `ValidateACMEToken()` restricts to base64url characters. The network scanner filters reserved IP ranges (loopback, link-local including cloud metadata 169.254.169.254, multicast, broadcast) to prevent SSRF, while preserving RFC 1918 private ranges for legitimate internal scanning.
+
+### Request Body Size Limits
+
+All incoming HTTP request bodies are capped by `http.MaxBytesReader` middleware (default 1MB, configurable via `CERTCTL_MAX_BODY_SIZE`). Requests exceeding the limit receive a 413 Request Entity Too Large response. The middleware is positioned before authentication in the chain so oversized payloads are rejected early, before any auth processing or database work occurs. Requests without bodies (GET, HEAD, nil body) skip the limit check.
+
+### CORS
+
+CORS uses a **deny-by-default** posture: when `CERTCTL_CORS_ORIGINS` is empty, no CORS headers are set and only same-origin requests can read responses. Operators must explicitly configure allowed origins. This prevents accidental exposure of the API to cross-origin requests in production.
+
+### Middleware Chain Order
+
+The HTTP middleware stack processes requests in the following order (see `cmd/server/main.go`):
+
+1. **RequestID** - assigns unique request ID for correlation
+2. **Logging** - structured slog middleware with request ID propagation
+3. **Recovery** - panic recovery (catches panics in downstream middleware/handlers)
+4. **BodyLimit** - request body size cap via `http.MaxBytesReader`
+5. **RateLimiter** - token bucket rate limiting (optional, when enabled)
+6. **CORS** - cross-origin request handling (deny-by-default)
+7. **Auth** - API key or JWT validation
+8. **AuditLog** - records every API call to the audit trail (requires auth context for actor)
+
+### Concurrency Safety
+
+The background scheduler uses `sync/atomic.Bool` idempotency guards on all 6 loops — if a tick fires while the previous iteration is still running, it skips. A `sync.WaitGroup` tracks all in-flight goroutines. `WaitForCompletion(timeout)` blocks during shutdown until all work finishes or the timeout expires, preventing state corruption from mid-flight database operations during process exit.
+
 ### Logging
 
 All logging throughout the service layer uses Go's `log/slog` package for structured, queryable logs. This replaces ad-hoc `fmt.Printf` statements with consistent key-value logging that includes request context, operation names, and error details. Agents also implement exponential backoff on network failures to gracefully handle temporary connectivity issues with the control plane.

The service layer threshold is deliberately lower because much of the service code depends on postgres repositories and external connectors that require real infrastructure to test meaningfully. Connector tests are included via `./internal/connector/issuer/...` and `./internal/connector/target/...` (covers Local CA, ACME, step-ca, NGINX, Apache, and HAProxy packages with unit tests for certificate signing logic, DNS solver, issuer validation, and deployment flows). The Frontend job runs `npx vitest run` between the TypeScript check and production build steps.
+**CI pipeline** (`.github/workflows/ci.yml`) — Two parallel jobs: Go (build, vet, race detection, static analysis, vulnerability scanning, test with coverage, coverage threshold enforcement) and Frontend (TypeScript type check, Vitest test suite, Vite production build). The Go job runs `go test -race` on service, handler, middleware, and scheduler packages to catch data races. It runs `golangci-lint` with 11 linters (errcheck, govet, staticcheck, unused, gosimple, ineffassign, typecheck, gocritic, gosec, bodyclose, noctx) configured in `.golangci.yml`. It runs `govulncheck ./...` to scan dependencies for known CVEs. Coverage thresholds are enforced per-layer: service 60%, handler 60%, domain 40%, middleware 50%. These thresholds act as regression floors — they can only go up. Connector tests are included via `./internal/connector/issuer/...` and `./internal/connector/target/...` (covers Local CA, ACME, step-ca, NGINX, Apache, HAProxy, Traefik, and Caddy packages with unit tests for certificate signing logic, DNS solver, issuer validation, and deployment flows). The Frontend job runs `npx vitest run` between the TypeScript check and production build steps.
 
-**Connector tests** (`internal/connector/`) — 57 test functions covering issuer, target, and notifier connectors. The Local CA connector has tests for self-signed and sub-CA modes (RSA, ECDSA, config validation, non-CA cert rejection). The ACME DNS solver has 6 tests for script-based DNS-01 challenges. The step-ca connector has tests with a mock HTTP server for issuance, renewal, revocation, and error paths. The OpenSSL/Custom CA connector has 14 tests covering config validation, issuance success/failure/timeout, renewal, revocation, and CRL generation. The NGINX target connector has 13 tests covering config validation, certificate deployment (file writing, permissions, validate/reload commands), and deployment validation. Apache httpd and HAProxy connectors each have 3 tests covering config validation, deployment, and validation flows. Notifier connector tests span 20 tests across Slack (5), Teams (4), PagerDuty (6), and OpsGenie (5) — verifying channel identity, payload formatting, HTTP error handling, connection failures, auth headers, and configuration defaults.

 ## What Is a TLS Certificate?
 
 When you visit `https://yourbank.com`, your browser checks a digital document called a **TLS certificate** before sending any data. That certificate proves two things: (1) you're really talking to yourbank.com and not an imposter, and (2) everything sent between you and the server is encrypted.

Instead of filling out forms and waiting for emails, ACME lets software request, validate, and receive certificates programmatically. The server proves domain ownership by responding to challenges — placing a specific file on the web server (HTTP-01) or creating a DNS record (DNS-01).

-certctl speaks ACME natively with both HTTP-01 and DNS-01 challenges, so it can request certificates — including wildcard certificates — from Let's Encrypt or any ACME-compatible CA without manual intervention. HTTP-01 uses a built-in temporary HTTP server for domain validation; DNS-01 uses pluggable script-based hooks to create TXT records with any DNS provider (Cloudflare, Route53, Azure DNS, etc.).

HTTP-01 uses a built-in temporary HTTP server for domain validation; DNS-01 uses pluggable script-based hooks to create TXT records with any DNS provider (Cloudflare, Route53, Azure DNS, etc.); DNS-PERSIST-01 creates a standing `_validation-persist` TXT record once (containing the CA domain and account URI) that the CA revalidates on every renewal — no per-renewal DNS updates needed. If the CA doesn't yet support DNS-PERSIST-01, certctl automatically falls back to DNS-01.
+
+### EST Protocol (Enrollment over Secure Transport)
+
+EST (RFC 7030) is a standard protocol for devices to request certificates from a CA. While ACME was designed for web servers proving domain ownership, EST was designed for devices that need certificates without domain validation — think WiFi access points, corporate laptops connecting to 802.1X networks, IoT devices, and mobile devices managed by MDM platforms.
+
+The workflow is straightforward: a device generates a key pair and a Certificate Signing Request (CSR), sends the CSR to the EST server, and gets back a signed certificate. The EST server also distributes its CA certificate chain so devices can build a complete trust path.
+
+certctl includes a built-in EST server at `/.well-known/est/` with four operations: distributing the CA certificate chain (`/cacerts`), enrolling new devices (`/simpleenroll`), renewing existing certificates (`/simplereenroll`), and advertising CSR requirements (`/csrattrs`). EST enrollment uses the same issuer connectors as the REST API — so a certificate issued via EST and a certificate issued via the dashboard go through the same CA, appear in the same inventory, and follow the same policies.

The CLI wraps the REST API with 10 subcommands: `list-certs`, `get-cert`, `renew-cert`, `revoke-cert`, `list-agents`, `list-jobs`, `health`, `metrics`, and `import` (for bulk PEM import).
+certctl ships with a command-line tool (`certctl-cli`) for operators who prefer terminal workflows or need to integrate certctl into shell scripts and CI/CD pipelines. The CLI wraps the REST API with 12 subcommands organized by resource: `certs list`, `certs get`, `certs renew`, `certs revoke`, `agents list`, `agents get`, `jobs list`, `jobs get`, `jobs cancel`, `import` (bulk PEM import), `status` (health + summary stats), and `version`.
 
 The CLI supports both table and JSON output formats (`--format table` or `--format json`), connects to the server via `CERTCTL_SERVER_URL` and authenticates with `CERTCTL_API_KEY`. It's built with Go's standard library only — no external dependencies.
 
 ### MCP Server (AI Integration)
 
-certctl includes an MCP (Model Context Protocol) server that exposes all 78 API endpoints as MCP tools. This enables AI assistants like Claude, Cursor, and other MCP-compatible tools to interact with your certificate infrastructure using natural language — "show me all expiring certificates," "revoke the VPN cert," or "what agents are offline?"

This enables AI assistants like Claude, Cursor, and other MCP-compatible tools to interact with your certificate infrastructure using natural language — "show me all expiring certificates," "revoke the VPN cert," or "what agents are offline?"
 
 The MCP server is a separate binary (`cmd/mcp-server/`) that communicates via stdio transport and acts as a stateless HTTP proxy to the certctl REST API. It requires no additional infrastructure — just point it at your certctl server URL and API key.
 
+### EST Enrollment (Device Certificates)
+
+certctl's EST server enables device certificate enrollment for use cases that don't fit the traditional "ops team requests a cert via API" model. When a RADIUS server is configured to use certctl for 802.1X WiFi authentication, or an MDM platform enrolls corporate devices, they use the EST protocol at `/.well-known/est/`. The EST server validates the CSR, issues a certificate via the configured issuer connector, and returns it in PKCS#7 format — the standard wire format that every EST client understands. Each enrollment is recorded in the audit trail with the protocol, common name, SANs, issuer, and serial number.
+
+Enable it with `CERTCTL_EST_ENABLED=true`. Optionally bind enrollments to a specific issuer (`CERTCTL_EST_ISSUER_ID`) or certificate profile (`CERTCTL_EST_PROFILE_ID`) to constrain what EST clients can request.
+
 ### Certificate Discovery
 
 Certificate discovery is the process of automatically finding existing certificates in your infrastructure — certificates you didn't issue through certctl, possibly issued by other CAs or tools. This is essential for building a complete inventory before you can manage everything.

 **How it works:** There are two discovery modes. *Filesystem discovery* — agents scan configured directories (configured via `CERTCTL_DISCOVERY_DIRS`) for certificate files. On startup and every 6 hours, the agent walks directories recursively, parses PEM and DER files, extracts metadata, and reports findings to the control plane. *Network discovery* — the control plane itself probes TLS endpoints across configured CIDR ranges and ports (enabled via `CERTCTL_NETWORK_SCAN_ENABLED=true`). It connects to each endpoint, extracts certificates from the TLS handshake, and feeds results into the same discovery pipeline. This finds certificates on services you may not have agents on. In both cases, the server deduplicates by fingerprint and stores discovered certs with a status: **Unmanaged** (discovered but not yet managed), **Managed** (linked to a control plane cert), or **Dismissed** (operator decided not to manage it).
 
 This gives you a three-step triage workflow:
-1. **Discover** — Agents find all existing certs on your infrastructure
-2. **Triage** — Operators review discoveries and decide: claim it (enroll for management), or dismiss it (not worth managing)
+1. **Discover** — Agents scan filesystems and the server probes network endpoints to find all existing certs
+2. **Triage** — Operators review discoveries in the **Discovery** dashboard page and decide: claim it (link to a managed certificate) or dismiss it (not worth managing). The dashboard shows a summary stats bar (Unmanaged/Managed/Dismissed counts), filters by status and agent, and provides one-click claim and dismiss actions.
 3. **Baseline** — Once triaged, you have a complete baseline of what's deployed, what you're managing, and what's unmanaged
 
+Network scan targets are managed from the **Network Scans** dashboard page — create CIDR ranges and ports to probe, enable/disable targets, trigger on-demand scans, and view results. Discovered certificates from network scans appear in the same Discovery triage page alongside filesystem discoveries.
+
 This is a prerequisite for multi-CA migration, compliance audits, and building confidence that you've found all the certificates that matter.

 3. **Notifier Connector** — Sends alerts about certificate events (Email, Webhooks, Slack, Microsoft Teams, PagerDuty, OpsGenie implemented)
 
 All connectors accept JSON configuration at initialization, support config validation, and are registered in the service layer. Issuer connectors run on the control plane; target connectors run on agents. For network appliances where agents can't be installed, a **proxy agent** in the same network zone handles deployment — the server never initiates outbound connections.

+The ACME connector implements the full ACME v2 protocol using Go's `golang.org/x/crypto/acme` package. It supports three challenge methods:
 
 **HTTP-01 (default):** A built-in temporary HTTP server starts on demand during certificate issuance. The domain being validated must resolve to the machine running the connector, and the configured HTTP port must be reachable from the internet.
 
 **DNS-01 (for wildcards):** Creates DNS TXT records via user-provided scripts. Required for wildcard certificates (`*.example.com`) and hosts that can't serve HTTP on port 80. The connector invokes external scripts to create and clean up `_acme-challenge` TXT records, making it compatible with any DNS provider (Cloudflare, Route53, Azure DNS, etc.).
 
+**DNS-PERSIST-01 (standing record):** Creates a one-time persistent TXT record at `_validation-persist.<domain>` containing the CA's issuer domain and your ACME account URI. Once set, this record authorizes unlimited future certificate issuances without per-renewal DNS updates. Based on [draft-ietf-acme-dns-persist](https://datatracker.ietf.org/doc/draft-ietf-acme-dns-persist/) and CA/Browser Forum ballot SC-088v3. If the CA doesn't offer dns-persist-01 yet, the connector falls back to dns-01 automatically.

+

+- **OpenSSL/Custom CA**: Returns error — custom script-based CAs have no CA cert access through certctl.

+### Built-in: Traefik
 
-The F5 BIG-IP target connector interface is built with the iControl REST flow mapped out, but the actual API calls are not yet implemented. F5 appliances can't run agents directly, so this connector uses the **proxy agent pattern**: a designated agent in the same network zone picks up F5 deployment jobs and calls the iControl REST API. The server assigns the work; the proxy agent executes it. Implementation is planned for the paid V3 release.
+The Traefik connector uses Traefik's file provider — it writes certificate and key files to a watched directory, and Traefik automatically picks up the changes without any explicit reload command. This is the simplest deployment model: write the files, and Traefik does the rest.
 
-The planned flow is: authenticate via `POST /mgmt/shared/authn/login`, upload cert PEM via `POST /mgmt/tm/ltm/certificate`, update the SSL profile via `PATCH /mgmt/tm/ltm/profile/client-ssl/{profile}`, and validate deployment by checking profile status. Implementation is planned for a future release.

+  "cert_dir": "/etc/traefik/certs",
+  "cert_file": "site.crt",

+
+The `cert_dir` is the directory Traefik is configured to watch via its file provider (e.g., `providers.file.directory` in Traefik's static config). The connector writes `cert_file` and `key_file` into this directory with appropriate permissions. Traefik's file watcher detects the change and reloads the TLS configuration automatically.

+### Built-in: Caddy
+
+The Caddy connector supports two deployment modes — choose based on your Caddy setup:
+
+**API mode (recommended):** Posts the certificate directly to Caddy's admin API (`POST /load` or certificate-specific endpoints) for zero-downtime hot reload. Requires Caddy's admin API to be enabled and accessible from the agent.
+
+**File mode (fallback):** Writes cert and key files to disk, relying on Caddy's built-in file watcher or a manual reload. Use this when the admin API isn't available or when Caddy is configured to read certificates from disk.

+  "key_file": "site.key"
+}
+```
+
+When `mode` is `"api"`, the connector posts the certificate to the admin API endpoint. When `mode` is `"file"`, it writes files to `cert_dir` (same pattern as Traefik). The `admin_api` field is ignored in file mode.

+### ACME with ZeroSSL (Auto-EAB)
+
+ZeroSSL is a free ACME CA that requires External Account Binding (EAB) for account registration. certctl auto-fetches EAB credentials from ZeroSSL's public API when the directory URL is detected as ZeroSSL and no EAB credentials are provided — you just need an email address:
+
+```bash
+# Minimal config — certctl auto-fetches EAB credentials from ZeroSSL
+export CERTCTL_ACME_DIRECTORY_URL="https://acme.zerossl.com/v2/DV90"
+export CERTCTL_ACME_EMAIL="ops@example.com"
+```
+
+No dashboard visit, no manual EAB credential copy-paste. certctl calls `api.zerossl.com/acme/eab-credentials-email` with your email, gets back a KID + HMAC key, and uses them for ACME account registration automatically.
+
+If you already have EAB credentials (e.g., from the ZeroSSL dashboard or for other CAs like Google Trust Services or SSL.com), you can provide them explicitly:

+```bash

-# certctl Demo Guide
-
-A 5-10 minute guided walkthrough of certctl's dashboard and API. Perfect for stakeholder presentations and team demos.
-
-New to certificates? Read the [Concepts Guide](concepts.md) first. Want a hands-on demo where you issue certificates yourself? See the [Advanced Demo](demo-advanced.md).
-
-## Quick Start
-
-```bash
-git clone https://github.com/shankar0123/certctl.git
-cd certctl
-docker compose -f deploy/docker-compose.yml up -d --build
-```
-
-Wait ~30 seconds for PostgreSQL to initialize and the server to start, then open:
-
-**http://localhost:8443**
-
-You'll see the dashboard pre-loaded with 15 demo certificates across multiple teams, environments, and statuses — including expiring, expired, active, failed, wildcard, and in-progress renewals.
-
-## What You'll See
-
-### Dashboard Overview
-The main dashboard shows at a glance:
-- **Total certificates** managed across your infrastructure
-- **Expiring soon** — certificates within 30 days of expiration (yellow/red)
-- **Expired** — certificates past their expiration date
-- **Active** — healthy certificates with time remaining
-- **Renewal success rate** — percentage of automated renewals that succeeded
-
-Below the stats, interactive charts provide deeper visibility: an **expiration heatmap** (90-day weekly buckets), **renewal success rate trends** (30-day line chart), **certificate status distribution** (donut chart), and **issuance rate** (30-day bar chart).
-
-### Certificates View
-Click "Certificates" in the sidebar to see the full inventory:
-- Search by name or domain
-- Filter by status (Active, Expiring, Expired, Failed) or environment (Production, Staging)
-- Sort by any column
-- Click any row to see full details: metadata, version history, deployment targets, and audit trail
-
-### Demo Scenarios to Walk Through
-
-**1. "We're about to have an outage"**
-Filter by status → Expiring. You'll see `auth-production` (12 days), `cdn-production` (8 days), and `mail-production` (5 days). These are real alerts the platform would catch automatically.
-
-**2. "A renewal failed"**
-Look at `vpn-production` — status: Failed. Click it to see the audit trail showing the ACME challenge failure after 3 retry attempts. The system sent a webhook notification to the ops channel.
-
-**3. "Who owns this cert?"**
-Click any certificate to see the owner, team, environment, and tags. Every cert has clear accountability.
-
-**4. "What happened to the legacy app?"**
-Filter by status → Expired. `legacy-app` expired 3 days ago, `old-api-v1` expired 15 days ago. Both have policy violations flagged.
-
-**5. "Show me the agent fleet"**
-Click "Agents" in the sidebar. Four agents are online, one (`iis-prod-agent`) went offline 3 hours ago — you'd want to investigate that.
-
-**6. "What policies are enforced?"**
-Click "Policies" to see the active rules: required owner metadata, allowed environments, max certificate lifetime, minimum renewal window. Check the violations list to see which certs are non-compliant.
-
-**7. "Can I revoke a compromised cert?"**
-Click any active certificate, then click the "Revoke" button. A modal appears with RFC 5280 reason codes (Key Compromise, Superseded, Cessation of Operation, etc.). After revocation, the cert shows a revocation banner with the reason and timestamp.
-
-**8. "Show me short-lived credentials"**
-Click "Short-Lived" in the sidebar. This view shows certificates with TTL under 1 hour — live countdown timers, auto-refresh every 10 seconds, and profile-based filtering. These are for service-to-service auth where rapid expiry replaces revocation.
-
-**9. "What about bulk operations?"**
-On the Certificates page, select multiple certificates using the checkboxes. A bulk action bar appears with options to trigger renewal, revoke (with reason codes), or reassign ownership — all with progress tracking.
-
-**10. "How do I see the deployment history?"**
-Click any certificate, then scroll to the deployment timeline. A visual 4-step timeline shows the lifecycle: Requested → Issued → Deploying → Active. Previous versions show a rollback button.
-
-**11. "What about certificates already running in production?"**
-Enable discovery on agents by setting `CERTCTL_DISCOVERY_DIRS` to directories containing certificates (e.g., `/etc/nginx/certs`). Agents scan on startup and every 6 hours, report findings to the control plane. For network-based discovery without agents, enable `CERTCTL_NETWORK_SCAN_ENABLED=true` and configure scan targets via the API — the server probes TLS endpoints on configured CIDR ranges and ports. Click "Discovered Certificates" to see what agents and network scans found — claim unmanaged certs to bring them under certctl's management, or dismiss them.

-
-## MCP Server for AI Integration
-
-certctl exposes its 78 API endpoints as tools via the Model Context Protocol (MCP), enabling integration with Claude, Cursor, and other AI assistants:
-
-```bash
-# Build and run the MCP server
-cd cmd/mcp-server && go build -o mcp-server .
-
-export CERTCTL_SERVER_URL="http://localhost:8443"
-export CERTCTL_API_KEY="test-key-123"
-
-./mcp-server
-```
-
-The MCP server:
-- Exposes all 78 API endpoints as MCP tools with typed schemas
-- Handles binary responses (DER CRL, OCSP responses)
-- Uses stdio transport for Claude/Cursor/OpenClaw integration
-- Zero external dependencies — pure Go with official MCP SDK
-
-You can then ask Claude questions like:
-- "What certificates are expiring in the next 30 days?"
-- "Revoke the payments certificate due to key compromise"
-- "Show me the audit trail for the last 10 actions"
-- "List all certificates with PCI compliance tags"
-
-## Dashboard Demo Mode
-
-The dashboard includes a **Demo Mode** that works without any backend. Build and serve the frontend with Vite:
-
-```bash
-cd web
-npm install
-npm run dev
-# Dashboard available at http://localhost:5173
-```
-
-When the API is unreachable, the dashboard automatically loads realistic mock data and shows a subtle "Demo Mode" badge. This is perfect for screenshots, presentations, or quick demos without any infrastructure.
-
-## Teardown
-
-```bash
-docker compose -f deploy/docker-compose.yml down -v
-```
-
-The `-v` flag removes the PostgreSQL data volume so you get a clean slate next time.
-
-## Presenting to Stakeholders
-
-If you're demoing to a team or customer, here's a suggested flow:
-
-1. **Start with the dashboard** — "This is your certificate inventory at a glance, with real-time charts showing expiration trends and renewal health"
-2. **Show the expiring certs** — "These three would have caused outages without this platform"
-3. **Click into auth-production** — "Here's the full lifecycle: who owns it, where it's deployed, deployment timeline, when it was last renewed"
-4. **Show revocation** — "If a key is compromised, one click revokes the cert with an RFC 5280 reason code. CRL and OCSP are served automatically"
-5. **Show the failed VPN cert** — "The system tried 3 times, then alerted the team via Slack, Teams, PagerDuty, or OpsGenie"
-6. **Show agents and fleet overview** — "Agents run on your infrastructure, handle key generation locally (ECDSA P-256). Fleet view shows OS, architecture, and version distribution"
-7. **Show profiles** — "Certificate profiles enforce crypto constraints — key types, max TTL, compliance requirements"
-8. **Show policies** — "Guardrails prevent teams from going outside approved scope"
-9. **Show bulk operations** — "Select multiple certs, trigger renewal or revoke in bulk with progress tracking"
-10. **Show certificate discovery** — "We discover certificates two ways: agents scan local filesystems, and the server actively probes TLS endpoints on your network. We deduplicate by fingerprint, show you what we found, and let you claim them or dismiss them"
-11. **Show the immutable audit trail** — "Every action in the system is recorded: who did it, what they did, when, what changed. Export to CSV/JSON for compliance"
-12. **Show advanced query features** — "Sort by any field, filter by date range, paginate efficiently with cursor-based pagination, select just the fields you need"
-13. **Show the CLI and MCP server** — "Terminal users get `certctl-cli` with 10 subcommands. AI assistants get MCP integration with 78 tools. Everything is API-first"
-
-The whole walkthrough takes 5-10 minutes.

+### Post-Deployment TLS Verification (M25)
+
+After deploying a certificate, the agent connects back to the target's live TLS endpoint and verifies the served certificate matches what was deployed — using SHA-256 fingerprint comparison. This catches failures that deployment commands can't: wrong virtual host, stale cache, config that validates but doesn't apply.

+### EST Server (RFC 7030, M23)
+**Enrollment over Secure Transport** — industry-standard protocol for device certificate enrollment. Enables WiFi/802.1X, MDM, IoT, and BYOD use cases where devices need certificates without direct API access.
+
+**Endpoints** (under `/.well-known/est/` per RFC 7030):
+
+| Endpoint | Method | Description | Wire Format |
+|----------|--------|-------------|-------------|
+| `/cacerts` | GET | CA certificate chain distribution | Base64 PKCS#7 certs-only (application/pkcs7-mime) |
+| `/simpleenroll` | POST | Initial certificate enrollment | Request: PEM or base64-DER PKCS#10; Response: PKCS#7 |
+| `/simplereenroll` | POST | Certificate re-enrollment (renewal) | Same as simpleenroll |
+| `/csrattrs` | GET | CSR attributes the server requires | ASN.1 DER (application/csrattrs) |
+
+**Architecture:**
+- **ESTService** bridges handler to existing `IssuerConnector` — no new issuance logic, reuses existing CA connectors
+- **CSR input handling** — accepts both base64-encoded DER (EST wire standard) and PEM-encoded PKCS#10 (convenience)
+- **PKCS#7 output** — hand-rolled ASN.1 degenerate SignedData builder (no external PKCS#7 dependency)
+- **CSR validation** — signature verification, Common Name extraction, SAN extraction (DNS, IP, email, URI)
+- **Configurable issuer binding** — `CERTCTL_EST_ISSUER_ID` selects which issuer connector processes enrollment
+- **Optional profile binding** — `CERTCTL_EST_PROFILE_ID` constrains enrollments to a specific certificate profile
+- **Audit trail** — all EST enrollments recorded with protocol=EST, CN, SANs, issuer ID, serial, profile ID
+
+**Configuration:**
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `CERTCTL_EST_ENABLED` | `false` | Enable EST enrollment endpoints |
+| `CERTCTL_EST_ISSUER_ID` | `iss-local` | Issuer connector for EST enrollments |
+| `CERTCTL_EST_PROFILE_ID` | — | Optional profile ID to constrain enrollments |

 # Quick Start Guide
 
-Get certctl running locally and managing certificates in under 5 minutes. With TLS certificate lifespans dropping to 47 days by 2029, automated lifecycle management isn't optional — it's infrastructure. This guide gets you hands-on with certctl's automation loop: tracking, renewing, and deploying certificates without manual intervention.
+Certificate lifespans are dropping to **47 days by 2029**. At that cadence, a team managing 100 certificates is processing 7+ renewals per week — every week, forever. Manual processes break. certctl automates the entire lifecycle: issuance, renewal, deployment, revocation, and audit — with zero human intervention.
+
+This guide gets you running in 5 minutes and walks you through everything certctl does.
 
 New to certificates? Read the [Concepts Guide](concepts.md) first — it explains TLS, CAs, and private keys in plain language.

+The dashboard comes pre-loaded with 15 demo certificates across multiple teams, environments, and statuses — expiring certs, expired certs, active certs, failed renewals. A realistic snapshot of what certificate management looks like in a real organization.
+
+### What you're looking at
+
+The main dashboard shows total certificates, how many are expiring soon, how many have expired, the renewal success rate, and four charts: an **expiration heatmap** (90-day weekly buckets), **renewal success rate trends** (30-day line chart), **certificate status distribution** (donut chart), and **issuance rate** (30-day bar chart).
+
+Explore the sidebar: Certificates, Agents, Policies, Jobs, Audit Trail, Notifications, Profiles, Teams, Owners, Agent Groups, Fleet Overview, Short-Lived Credentials, Discovery, and Network Scans.
+
+### Scenarios to walk through
+
+**"We're about to have an outage"** — Filter certificates by status → Expiring. You'll see `auth-production` (12 days), `cdn-production` (8 days), and `mail-production` (5 days). At 47-day lifespans, this is every other week. certctl catches these automatically and triggers renewal before they expire.
+
+**"A renewal failed"** — Look at `vpn-production` — status: Failed. Click it to see the audit trail showing the ACME challenge failure after 3 retry attempts. The system sent a webhook notification to the ops channel. No one had to notice manually.
+
+**"Who owns this cert?"** — Click any certificate. Owner, team, environment, tags. Clear accountability. Notifications route to the owner's email automatically.
+
+**"Can I revoke a compromised cert?"** — Click any active certificate, then "Revoke." A modal with RFC 5280 reason codes (Key Compromise, Superseded, Cessation of Operation). After revocation, CRL and OCSP are served automatically — clients stop trusting the cert immediately.
+
+**"What about certificates already in production?"** — Click "Discovery" in the sidebar. The demo comes pre-loaded with 9 discovered certificates — some found by agents scanning filesystems, some found by the server probing TLS endpoints on the network. You'll see Unmanaged certs waiting for triage (including an expired printer cert and an expiring switch management cert), certs already linked to managed inventory, and one that was dismissed. Claim unmanaged certs to bring them under automation, or dismiss them. Click "Network Scans" to see the 3 configured scan targets with recent scan results.
+
+**"I need to approve a renewal before it proceeds"** — Click "Jobs" in the sidebar. You'll see an amber banner: "2 jobs awaiting approval." These are renewal jobs for `auth-production` and `payments-production` that require human sign-off before proceeding. Click Approve or Reject with a reason — the decision is recorded in the audit trail.
+
+**"Show me the agent fleet"** — Click "Agents." Four agents online, one offline. Click "Fleet Overview" for OS/architecture grouping, version distribution, and per-platform listing. Agents generate ECDSA P-256 keys locally — private keys never leave your infrastructure.
+
+**"What about bulk operations?"** — On the Certificates page, select multiple certificates with checkboxes. A bulk action bar appears: trigger renewal, revoke with reason codes, or reassign ownership — all with progress tracking. At 47-day lifespans with hundreds of certs, bulk operations aren't optional.
+
+**"Short-lived credentials?"** — Click "Short-Lived" in the sidebar. Live countdown timers for certificates with TTL under 1 hour. Auto-refresh every 10 seconds. These are for service-to-service auth where rapid expiry replaces revocation.

 ## Create Your First Certificate
 
-Let's create a new managed certificate from scratch using the API. This will create a certificate record that certctl will track, renew, and deploy.
-
-### Step 1: Create a certificate

-The server returns the created certificate. Since we didn't include an `id` field, the server auto-generates one using the name and a timestamp:
-```json
-{
-  "id": "My First Certificate-1710403200000000000",
-  "name": "My First Certificate",
-  "common_name": "myapp.example.com",
-  "status": "Pending",
-  "created_at": "2026-03-14T..."

-```
-
 Save the certificate ID (or provide your own `id` in the request body, e.g. `"id": "mc-my-first"`):
 ```bash
 CERT_ID="<paste the id from the response>"
 ```
 
-### Step 2: Trigger renewal
-
+Trigger renewal:
 ```bash
 curl -s -X POST http://localhost:8443/api/v1/certificates/$CERT_ID/renew | jq .

-## Understanding the Demo Data
-
-The demo comes pre-loaded with realistic data so you can explore certctl's features immediately:
-
-| Resource | Count | Examples |
-|----------|-------|---------|
-| Teams | 5 | Platform, Security, Payments, Frontend, Data |
-| Owners | 5 | Alice, Bob, Carol, Dave, Eve |
-| Issuers | 4 | Local Dev CA, Let's Encrypt Staging, step-ca Internal, DigiCert (disabled) |
-| Agents | 5 | nginx-prod, nginx-staging, f5-prod, iis-prod, data-agent |
-| Targets | 5 | NGINX (prod/staging/data), F5 LB, IIS |
-| Certificates | 15 | Various statuses: Active, Expiring, Expired, Failed, Wildcard |
-| Policies | 4 | Required owner, allowed environments, max lifetime, min renewal window |
-| Profiles | 3 | Default TLS, Short-Lived, High-Security |
-| Agent Groups | 5 | Linux agents, ARM agents, Production subnet, etc. |
-
-Certificates have varied statuses so you can see what each state looks like in the dashboard: healthy certs with 45+ days remaining, certs about to expire (5-12 days), certs that already expired, and a failed renewal.
-
-## Advanced API Features
-
-### Sorting and filtering
-
-```bash
-# Sort certificates by expiration date (ascending)
-curl -s "http://localhost:8443/api/v1/certificates?sort=notAfter" | jq .
-
-# Sort descending (prefix with -)
-curl -s "http://localhost:8443/api/v1/certificates?sort=-createdAt" | jq .
-
-# Time-range filters (RFC3339 format)
-curl -s "http://localhost:8443/api/v1/certificates?expires_before=2026-05-01T00:00:00Z" | jq .
-curl -s "http://localhost:8443/api/v1/certificates?created_after=2026-03-01T00:00:00Z" | jq .
-```
-
-Supported sort fields: `notAfter`, `expiresAt`, `createdAt`, `updatedAt`, `commonName`, `name`, `status`, `environment`.
-
-### Sparse field selection
-
-Request only the fields you need to reduce response size:
-
-```bash
-curl -s "http://localhost:8443/api/v1/certificates?fields=id,common_name,status,expires_at" | jq .
-```
-
-### Cursor-based pagination
-
-For large datasets, cursor pagination is more efficient than page-based:
-
-```bash
-# First page
-curl -s "http://localhost:8443/api/v1/certificates?page_size=5" | jq '{next_cursor: .next_cursor, count: (.data | length)}'
-
-# Next page (use the next_cursor from the previous response)

 ### Interactive approval workflow
 
+For high-value certificates where you want human oversight. The demo includes 2 pre-seeded jobs in `AwaitingApproval` status (for `auth-production` and `payments-production`). Open **Jobs** in the sidebar and you'll see the amber "Pending Approval" banner immediately.

-## Tear Down
+## Certificate Discovery
 
-```bash
-docker compose -f deploy/docker-compose.yml down -v
-```
+Find certificates already running in your infrastructure — ones you didn't issue through certctl.
 
-The `-v` flag removes the PostgreSQL data volume so you get a clean slate next time.
+The demo environment comes pre-loaded with 9 discovered certificates (from agent filesystem scans and server-side network scans), 3 network scan targets, and recent scan history. Open **Discovery** and **Network Scans** in the sidebar to see the triage workflow immediately.
 
-### Certificate Discovery
-
-Agents can scan your infrastructure for existing certificates you're not yet managing:
+### Filesystem discovery (agent-based)
 
 ```bash
 # Configure agent to scan directories
 export CERTCTL_DISCOVERY_DIRS="/etc/nginx/certs,/etc/ssl/certs,/var/lib/certs"
-

+
+## Dashboard Demo Mode
+
+The dashboard works without a backend for screenshots and presentations:
+
+```bash
+cd web && npm install && npm run dev
+# Dashboard at http://localhost:5173
+```
+
+When the API is unreachable, the dashboard loads realistic mock data with a "Demo Mode" badge.
+
+## Presenting to Stakeholders
+
+A suggested 5-minute flow:
+
+1. **Dashboard** — "Certificate inventory at a glance. Real-time charts show expiration trends and renewal health."
+2. **Expiring certs** — "These three would have caused outages. At 47-day lifespans, this happens every other week."
+3. **Certificate detail** — "Full lifecycle: who owns it, where it's deployed, deployment timeline, version history with rollback."
+4. **Revocation** — "One click revokes with an RFC 5280 reason code. CRL and OCSP served automatically."
+5. **Failed renewal** — "System tried 3 times, then alerted the team via Slack, Teams, PagerDuty, or OpsGenie."
+6. **Agent fleet** — "Agents handle key generation locally (ECDSA P-256). Private keys never leave your infrastructure."
+7. **Discovery** — "Agents scan filesystems, server probes TLS endpoints. We find what you're not managing yet."
+8. **Bulk operations** — "Select multiple certs, renew or revoke in bulk. At 47-day lifespans with hundreds of certs, this is essential."
+9. **Audit trail** — "Every action recorded. Export to CSV/JSON for compliance."
+10. **CLI + MCP** — "Terminal users get `certctl-cli`. AI assistants get MCP integration. Everything is API-first."
+
+## Tear Down
+
+```bash
+docker compose -f deploy/docker-compose.yml down -v
+```
+
+The `-v` flag removes the PostgreSQL data volume for a clean slate.

+### Why manual QA on top of automated tests?
 
 Automated tests mock dependencies and run in isolation. Manual QA validates the full integrated stack: real PostgreSQL, real HTTP, real agent binary, real file I/O, real scheduler timing. It catches issues that unit tests can't: migration ordering, Docker networking, env var parsing, browser rendering, and timing-dependent scheduler behavior.

+### 6.2 ACME DNS Challenge Configuration
+
+**Test 6.2.1 — List ACME issuer with DNS-01 configuration**
+
+```bash
+curl -s -H "$AUTH" "$SERVER/api/v1/issuers/iss-acme-le" | jq '{id, type, config}'
+```
+
+**What:** Retrieves the ACME Let's Encrypt issuer and verifies its configuration.
+**Why:** ACME issuers configured for DNS-01 challenges need their solver scripts accessible for wildcard certificate support.
+**Expected:** HTTP 200. `type` = "acme". `config` may include challenge type and DNS script paths.
+**PASS if** HTTP 200 and type matches. **FAIL** otherwise.
+
+---
+
+**Test 6.2.2 — Create ACME issuer with DNS-PERSIST-01**
+
+Edit `deploy/docker-compose.yml` to set environment variables for ACME DNS-PERSIST-01:
+- `CERTCTL_ACME_CHALLENGE_TYPE: dns-persist-01`
+- `CERTCTL_ACME_DNS_PERSIST_ISSUER_DOMAIN: le.example.com`
+- `CERTCTL_ACME_DNS_PRESENT_SCRIPT: /usr/local/bin/dns-present.sh`
+- `CERTCTL_ACME_DNS_CLEANUP_SCRIPT: /usr/local/bin/dns-cleanup.sh`
+
+Restart and verify the issuer accepts the config:
+
+```bash
+curl -s -H "$AUTH" "$SERVER/api/v1/issuers/iss-acme-le" | jq '{id, type}'
+```
+
+**What:** Verifies that ACME issuers read DNS-PERSIST-01 configuration from environment variables.
+**Why:** DNS-PERSIST-01 requires a standing TXT record per IETF draft. The issuer must know the issuer domain and support this challenge type.
+**Expected:** HTTP 200. ACME issuer still functional.
+**PASS if** HTTP 200 and issuer still works. **FAIL** if 500 or issuer broken.
+
+---
+
+**Test 6.2.3 — Configure ACME with External Account Binding (ZeroSSL)**
+
+Edit `deploy/docker-compose.yml` to set EAB environment variables:
+- `CERTCTL_ACME_DIRECTORY_URL: https://acme.zerossl.com/v2/DV90`
+- `CERTCTL_ACME_EAB_KID: your-zerossl-kid`
+- `CERTCTL_ACME_EAB_HMAC: your-base64url-hmac-key`
+
+Restart and verify the issuer accepts the config:
+
+```bash
+curl -s -H "$AUTH" "$SERVER/api/v1/issuers/iss-acme-prod" | jq '{id, type}'
+```
+
+**What:** Verifies that ACME issuers read External Account Binding credentials from environment variables.
+**Why:** ZeroSSL, Google Trust Services, and SSL.com require EAB for ACME account registration. Without EAB, account creation fails and no certificates can be issued from these CAs.
+**Expected:** HTTP 200. ACME issuer functional with EAB credentials loaded.
+**PASS if** HTTP 200 and issuer responds. **FAIL** if 500 or startup errors related to EAB.
+
+---
+

+### 11.4 Foreign Key Constraint Behavior
+
+**What this validates:** Delete operations correctly fail with 409 when referenced entities still exist.
+
+**Why it matters:** Owners and issuers use `ON DELETE RESTRICT` — you can't delete them while certificates reference them. Teams use `ON DELETE CASCADE`, so team deletes succeed and cascade. If the server returns a silent 500 instead of 409, the GUI swallows the error and the user thinks nothing happened.
+
+**Test 11.4.1 — Delete owner with assigned certificates (expect 409)**
+
+```bash
+# Try to delete Alice Chen (o-alice) — she owns certificates in the demo data
+curl -s -w "\nHTTP %{http_code}\n" -X DELETE -H "$AUTH" "$SERVER/api/v1/owners/o-alice" | jq .
+```
+
+**Expected:** HTTP 409 with message "Cannot delete owner: certificates are still assigned to this owner".

+
+**Expected:** HTTP 409 with message "Cannot delete issuer: certificates are still using this issuer".
+**PASS if** 409 Conflict. **FAIL** if 204 or 500.
+

+
+**Test 11.4.3 — Delete team cascades successfully**

+# Create a test team, then delete it — teams use ON DELETE CASCADE
+curl -s -X POST -H "$AUTH" -H "$CT" -d '{"id": "t-fk-test", "name": "FK Test Team"}' $SERVER/api/v1/teams > /dev/null

+```
+
+**Expected:** At least one audit event with `action: "est_simple_enroll"`, `protocol: "EST"` in details, and the enrolled CN in the details.
+**PASS if** audit event found with correct action and details.
+
+---
+
+**Test 26.14 — EST disabled returns 404**
+
+With `CERTCTL_EST_ENABLED=false` (default), EST endpoints should not be registered:
+
+```bash
+curl -s -o /dev/null -w "%{http_code}" http://localhost:8443/.well-known/est/cacerts
+```
+
+**Expected:** HTTP 404 Not Found (endpoints not registered when EST is disabled).
+**PASS if** status = 404.
+
+---
+
+**Test 26.15 — EST with profile binding**
+
+With `CERTCTL_EST_PROFILE_ID=profile-wifi-client`, verify that audit events include the profile_id in their details:
+
+```bash
+# After enrollment with profile binding, check audit
+curl -s -H "Authorization: Bearer $API_KEY" \
+  "http://localhost:8443/api/v1/audit?page=1&per_page=5" | \
+  jq '.data[0].details.profile_id'
+```
+
+**Expected:** Profile ID appears in audit event details when configured.
+**PASS if** `profile_id` present in audit details.
+
+---
+
+## Part 27: Post-Deployment TLS Verification
+
+### Why test this?
+
+Post-deployment verification is the final confidence check: after a certificate is deployed to a target, the agent probes the live TLS endpoint and confirms the served certificate matches what was deployed. This catches silent failures where a reload command exits 0 but the certificate doesn't take effect.
+
+### 27.1: Submit Verification Result (Success)
+
+```bash
+# Create a deployment job first (or use an existing completed deployment job ID)
+JOB_ID="j-deploy-001"
+
+# Submit a successful verification result
+curl -X POST -H "$AUTH" -H "$CT" $SERVER/api/v1/jobs/$JOB_ID/verify -d '{
+  "target_id": "tgt-nginx-prod",
+  "expected_fingerprint": "sha256:abc123def456",
+  "actual_fingerprint": "sha256:abc123def456",
+  "verified": true
+}'
+```
+
+**Expected:** 200 OK with `{"job_id": "j-deploy-001", "verified": true, "verified_at": "..."}`.
+**PASS if** response contains `verified: true` and a valid `verified_at` timestamp.
+
+### 27.2: Submit Verification Result (Failure — Fingerprint Mismatch)
+
+```bash
+curl -X POST -H "$AUTH" -H "$CT" $SERVER/api/v1/jobs/$JOB_ID/verify -d '{
+  "target_id": "tgt-nginx-prod",
+  "expected_fingerprint": "sha256:abc123def456",
+  "actual_fingerprint": "sha256:zzz999different",
+  "verified": false,
+  "error": "fingerprint mismatch"
+}'
+```
+
+**Expected:** 200 OK with `verified: false`.
+**PASS if** verification failure recorded without error status code (verification is best-effort).
+
+### 27.3: Get Verification Status
+
+```bash
+curl -H "$AUTH" $SERVER/api/v1/jobs/$JOB_ID/verification | jq .
+```
+
+**Expected:** Returns the verification result previously submitted.
+**PASS if** response includes `job_id`, `verified`, `verified_at`, and `actual_fingerprint`.
+
+### 27.4: Missing Required Fields
+
+```bash
+# Missing target_id
+curl -X POST -H "$AUTH" -H "$CT" $SERVER/api/v1/jobs/$JOB_ID/verify -d '{
+  "expected_fingerprint": "sha256:abc",
+  "actual_fingerprint": "sha256:abc",
+  "verified": true
+}'
+```
+
+**Expected:** 400 Bad Request with message about missing `target_id`.
+**PASS if** status code is 400.
+
+### 27.5: Audit Trail
+
+```bash
+curl -H "$AUTH" "$SERVER/api/v1/audit?action=job_verification_success" | jq '.data[0]'
+```
+
+**Expected:** Audit event recorded with verification details (job_id, target_id, fingerprints).
+**PASS if** audit event exists with expected action and details.
+
+### 27.6: Database Schema Verification
+
+```bash
+docker compose exec postgres psql -U certctl -d certctl -c \
+  "SELECT column_name, data_type FROM information_schema.columns WHERE table_name='jobs' AND column_name LIKE 'verification%';"
+```
+
+**Expected:** Four columns: `verification_status`, `verified_at`, `verification_fingerprint`, `verification_error`.
+**PASS if** all four columns exist with correct types.
+

+
+## Part 28: Traefik & Caddy Target Connectors
+
+### Why test this?
+
+Traefik and Caddy are increasingly popular reverse proxies. Testing ensures cert deployment works with their specific file-watching and admin API patterns.
+
+### 28.1: Traefik File Provider Deployment
+
+**Setup:** Configure a target with type `Traefik` pointing to a test directory.
+
+```bash
+# Create a Traefik target
+curl -X POST -H "$AUTH" -H "$CT" $SERVER/api/v1/targets -d '{
+  "name": "Traefik Test",
+  "type": "Traefik",
+  "agent_id": "a-test-agent",
+  "config": {
+    "cert_dir": "/tmp/traefik-certs",
+    "cert_file": "test.crt",
+    "key_file": "test.key"
+  }
+}'
+```
+
+**Expected:** 201 Created with target details.
+**PASS if** target created with type `Traefik` and config fields preserved.
+
+### 28.2: Caddy API Mode Deployment
+
+```bash
+# Create a Caddy target in API mode
+curl -X POST -H "$AUTH" -H "$CT" $SERVER/api/v1/targets -d '{
+  "name": "Caddy API Test",
+  "type": "Caddy",
+  "agent_id": "a-test-agent",
+  "config": {
+    "mode": "api",
+    "admin_api": "http://localhost:2019",
+    "cert_dir": "/etc/caddy/certs",
+    "cert_file": "test.crt",
+    "key_file": "test.key"
+  }
+}'
+```
+
+**Expected:** 201 Created.
+**PASS if** target created with mode `api` and `admin_api` URL preserved.
+
+### 28.3: Caddy File Mode Deployment
+
+```bash
+# Create a Caddy target in file mode
+curl -X POST -H "$AUTH" -H "$CT" $SERVER/api/v1/targets -d '{
+  "name": "Caddy File Test",
+  "type": "Caddy",
+  "agent_id": "a-test-agent",
+  "config": {
+    "mode": "file",
+    "cert_dir": "/etc/caddy/certs",
+    "cert_file": "test.crt",
+    "key_file": "test.key"
+  }
+}'
+```
+
+**Expected:** 201 Created.
+**PASS if** target created with mode `file`.
+
+### 28.4: Agent Connector Dispatch
+
+Verify the agent binary recognizes Traefik and Caddy target types from the work endpoint response. This requires a running agent with deployment jobs assigned to Traefik/Caddy targets.
+
+**Expected:** Agent logs show connector instantiation for the target type (e.g., "deploying to Traefik target" or "deploying to Caddy target").
+**PASS if** agent does not error with "unknown target type" for Traefik or Caddy.
+
+### 28.5: Connector Unit Tests
+
+```bash
+go test ./internal/connector/target/traefik/... -v
+go test ./internal/connector/target/caddy/... -v
+```
+
+**Expected:** All tests pass.
+**PASS if** exit code 0 for both test suites.
+

+# Why certctl?
+
+Certificate management is broken at every scale between "one domain on Let's Encrypt" and "Fortune 500 budget for Venafi."
+
+If you run a personal blog, Certbot works fine. If your company spends $200K/year on Keyfactor, you're covered. But if you're an ops engineer managing 20-500 certificates across NGINX, Apache, HAProxy, and maybe a private CA — the tools available today either don't do enough or cost too much.
+
+certctl fills that gap.
+
+## The Problem
+
+The CA/Browser Forum passed [Ballot SC-081v3](https://cabforum.org/2025/04/11/ballot-sc081v3-introduce-schedule-of-reducing-validity-and-data-reuse-periods/) in April 2025, mandating a phased reduction in TLS certificate lifetimes: 200 days as of March 2026, 100 days by March 2027, and 47 days by March 2029. That means every organization needs automated certificate renewal — not eventually, but now.
+
+The existing options for automation are:
+
+- **ACME clients** (Certbot, Lego, CertWarden): Handle issuance and renewal for ACME-compatible CAs, but don't manage deployment to target servers, don't provide inventory visibility, don't support non-ACME CAs, and don't offer audit trails or policy enforcement.
+- **Kubernetes-native** (cert-manager): Works well inside Kubernetes, but if your infrastructure includes bare-metal servers, VMs, or network appliances alongside Kubernetes, you need a separate solution for everything cert-manager can't reach.
+- **Commercial SaaS** (CertKit, Sectigo CLM): Handle more of the lifecycle but are proprietary, cloud-dependent, and priced per certificate — costs scale linearly with your infrastructure.
+- **Enterprise platforms** (Venafi, Keyfactor, AppViewX): Comprehensive but start at $75K/year and require dedicated teams to operate.
+
+## What certctl Does Differently
+
+certctl is a self-hosted certificate lifecycle platform. It handles issuance, renewal, deployment, revocation, discovery, and monitoring — with three design decisions that no other tool at any price point combines:
+
+### 1. Private Keys Never Leave Your Infrastructure
+
+certctl agents generate private keys locally using ECDSA P-256. The agent creates a CSR and submits it to the control plane. The signed certificate comes back. The private key stays on the agent's filesystem with 0600 permissions.
+
+This isn't a premium feature — it's the default behavior in the free tier. Most competitors either generate keys server-side (creating a single point of compromise) or gate key isolation behind paid tiers.
+
+### 2. CA-Agnostic Issuer Architecture
+
+certctl works with any certificate authority, not just ACME providers:
+
+- **ACME** (Let's Encrypt, ZeroSSL, Google Trust Services, Buypass) — HTTP-01 and DNS-01 challenges, DNS-PERSIST-01 for zero-touch renewals, External Account Binding
+- **step-ca** (Smallstep) — native /sign API with JWK provisioner authentication
+- **Local CA** — self-signed or sub-CA mode (chain to your enterprise root CA, e.g. ADCS)
+- **OpenSSL / Custom CA** — delegate signing to any shell script with configurable timeout
+- **EST enrollment** (RFC 7030) — device certificate enrollment for WiFi/802.1X, MDM, and IoT
+
+Every issuer connector implements the same interface. Switching CAs or running multiple CAs in parallel requires zero code changes — just configuration.
+
+### 3. Post-Deployment Verification
+
+Every other tool in this space stops at "the deployment command succeeded." certctl goes further: after deploying a certificate to a target, the agent connects back to the target's TLS endpoint and verifies the served certificate matches what was deployed, using SHA-256 fingerprint comparison.
+
+A reload command can exit 0 while the certificate doesn't take effect — wrong virtual host, stale cache, config that validates but doesn't apply. certctl catches this.
+
+## How certctl Compares
+
+### vs. CertKit
+
+Closest competitor architecturally — agent-based, private key isolation (Keystore), multi-platform. certctl leads on issuer coverage (ACME + step-ca + Local CA + OpenSSL + EST vs. ACME-only), PKI compliance (CRL, OCSP, RFC 5280 revocation, immutable audit trail — all missing from CertKit today), policy engine (5 rule types vs. none), and network discovery (CIDR TLS scanning vs. none). certctl is source-available (BSL 1.1 → Apache 2.0) with no cert limit; CertKit is proprietary SaaS with a 3-cert free tier. Where CertKit leads: more deployment targets today (adds LiteSpeed, IIS, auto-detection), Windows support, Kubernetes, and polished SaaS onboarding.
+
+### vs. KeyTalk
+
+Commercial (proprietary) PKI platform from a Dutch company — on-prem appliance, cloud, or managed service. Broader cert type coverage (TLS, S/MIME, device auth, VPN) and DigiCert + SCEP integrations. No public documentation on policy engine, API surface, or audit capabilities. No free tier, no public pricing. certctl trades breadth of cert types for full transparency — source-available, public API spec, free community edition with no limits.
+
+### vs. Enterprise Platforms (Venafi, Keyfactor)
+
+Comprehensive solutions with decades of features — at $75K-$250K+/yr. certctl targets organizations that need 80% of those capabilities at 1% of the cost. The trade-off: no SSO/RBAC yet (coming in certctl Pro), no F5/IIS target connectors yet, no SLA-backed support.
+
+## Getting Started
+
+```bash
+# Clone and start with Docker Compose (includes demo data)
+git clone https://github.com/shankar0123/certctl.git
+cd certctl/deploy
+docker compose up -d
+
+# Open the dashboard
+open http://localhost:8443
+```
+
+The demo seeds 15 certificates, 5 agents, 5 deployment targets, discovery data, network scan targets, and pending approval jobs so you can explore every feature immediately.
+
+See the [Quickstart Guide](quickstart.md) for a full walkthrough.
