Fixes 12 production bugs preventing the full issuance→deployment flow
from working with ACME (Pebble/Let's Encrypt) and step-ca issuers:
ACME connector (acme.go):
- Save orderURI before WaitOrder overwrites it (Go crypto/acme bug)
- Add CreateOrderCert fallback via WaitOrder+FetchCert
- Remove defer-reset in ValidateConfig that caused nil pointer panic
- Add Insecure TLS option for self-signed ACME servers (Pebble)
step-ca connector (stepca.go, jwe.go):
- Real JWE provisioner key loading + decryption (was using ephemeral keys)
- Fix JWT audience (/1.0/sign), sha claim (key fingerprint), kid header
- Custom root CA trust via RootCertPath config
- Remove hardcoded 90-day validity default (let step-ca decide)
NGINX target connector (nginx.go):
- Use sh -c for validate/reload commands (shell interpretation)
- Use filepath.Dir instead of fragile string slicing
- Add private key file writing (agent-mode keys were never deployed)
- Make chain_path write conditional
Server/service layer:
- TriggerRenewalWithActor now creates actual Job records (was no-op)
- createDeploymentJobs falls back to DB query when cert.TargetIDs empty
- ProcessPendingJobs skips agent-routed deployment jobs
- Agent cert pickup path parsing: len(parts)<4 → len(parts)<3
- Health/ready/auth-info endpoints bypass auth middleware
- Write timeout 15s→120s for ACME issuance
- Cert fingerprint computed on CSR submission
Integration test environment (deploy/test/):
- 10-phase test script covering Local CA, ACME, step-ca, revocation,
discovery, renewal, and API spot checks
- Docker Compose with 7 containers (server, agent, postgres, nginx,
pebble, challtestsrv, step-ca) on isolated network
- TLS verification checks SAN (not just Subject CN) for modern CA compat

Deployment jobs now set agent_id from target→agent relationship at
creation time. GetPendingWork() uses ListPendingByAgentID() with a
3-way UNION query (direct match, legacy NULL fallback via target JOIN,
AwaitingCSR via cert→target→agent chain) so each agent only receives
its own jobs.
- Added AgentID *string to Job domain struct
- Added agent_id to all job SQL queries (5 SELECTs, INSERT, UPDATE, scanJob)
- New ListPendingByAgentID() repository method
- Rewrote GetPendingWork() from ~25 lines to single scoped query
- 4 new Go tests (3 agent routing + 1 deployment agent_id)
- Frontend: agent_id/target_id on Job type

Add certificate export in PEM (JSON or file download) and PKCS#12 formats.
Private keys are never included — they stay on agents. Add EKU-aware
issuance threading profile EKUs (serverAuth, clientAuth, codeSigning,
emailProtection, timeStamping) through the full issuance pipeline. Fix
agent CSR SAN splitting for email addresses, adaptive KeyUsage flags for
S/MIME vs TLS, and a pre-existing generateID collision bug in deployment
job creation.

Six pages were read-only viewers despite the API client having all
create functions wired up. Users deploying certctl had no way to create
CAs or other objects from the GUI — reported in GitHub issue.
- IssuersPage: 2-step create modal (type selection → config) for
Local CA, ACME, step-ca, OpenSSL/Custom issuer types
- PoliciesPage: create modal with type, severity, JSON config, enabled
- ProfilesPage: create modal with name, description, max TTL, short-lived
- OwnersPage: create modal with name, email, team dropdown
- TeamsPage: create modal with name, description
- AgentGroupsPage: create modal with match criteria fields
- Layout.tsx: version v2.0.5 → v2.0.7
- cmd/server/main.go: version 0.1.0 → 2.0.7

Replace the 18-parameter RegisterHandlers function signature with a cleaner
HandlerRegistry struct that groups all API handler dependencies. This eliminates
the signature explosion that made the function difficult to read and maintain.
Changes:
- Added HandlerRegistry struct with 18 fields grouping all handler types
- Updated RegisterHandlers to accept a single HandlerRegistry parameter
- Updated all internal handler references to use reg.FieldName syntax
- Updated call sites in cmd/server/main.go and integration tests
- No functional changes, purely structural refactoring
Resolves TICKET-006: RegisterHandlers Signature Explosion
The generateTestCert() function previously returned &x509.Certificate{Raw: []byte("test")},
which is not a valid DER-encoded certificate. Replace with a proper self-signed certificate
generator using ECDSA P-256 that creates valid X.509 certificates for testing.
Added imports: crypto/ecdsa, crypto/elliptic, crypto/rand, crypto/x509/pkix, math/big

- Added TestSlack_ClientHasTimeout to verify 10-second timeout
- Added TestTeams_ClientHasTimeout to verify 10-second timeout
- Added TestPagerDuty_ClientHasTimeout to verify 10-second timeout
- Added TestOpsGenie_ClientHasTimeout to verify 10-second timeout
- All notifiers already configured with 10 second timeout in New()
- Tests verify timeout is set and matches expected value
- Fix undefined tls.Listener in verify_test.go (type doesn't exist in
crypto/tls); use server.Listener.Addr() and server.TLS.Certificates
- Fix mockJobRepository missing Delete/ListByStatus/ListByCertificate/
UpdateStatus/GetPendingJobs methods required by JobRepository interface
- Fix mockAuditService type mismatch: NewVerificationService expects
*AuditService (concrete), not a mock; use real AuditService with mock
repo following existing testutil_test.go patterns
- Fix List() signature mismatch (had extra filter param)
- Add nil-safe logger checks in verify.go to prevent panics in tests
- Remove unused imports (crypto/tls, bytes, repository)

M25: After deploying a certificate, the agent probes the live TLS
endpoint and compares SHA-256 fingerprints to verify the correct cert
is being served. Best-effort — failures don't block deployments.
New endpoints: POST /jobs/{id}/verify, GET /jobs/{id}/verification.
Migration 000008 adds verification columns to jobs table.
M26: Traefik target connector (file provider, auto-reload) and Caddy
target connector (dual-mode: admin API hot-reload or file-based).
Both wired into agent dispatch.
Also: restructured README to highlight supported integrations (issuers,
targets, notifiers) earlier, moved API/CLI/MCP sections lower. Updated
all docs (features, connectors, architecture, testing guide, why-certctl)
and fixed integration tests for 18-param RegisterHandlers signature.

EAB credentials (KID + HMAC) were defined in the ACME connector config
but never wired into the acme.Account registration call. This fixes the
dead code and adds automatic EAB credential fetching for ZeroSSL — when
the directory URL is detected as ZeroSSL and no EAB credentials are
provided, certctl calls ZeroSSL's public API to get them automatically.
Changes:
- Wire EABKid/EABHmac into acme.Account.ExternalAccountBinding
- Add isZeroSSL() detection and fetchZeroSSLEAB() auto-fetch
- Add CERTCTL_ACME_EAB_KID/CERTCTL_ACME_EAB_HMAC env vars to main.go
- Add 13 ACME connector tests (config validation, EAB decode, ZeroSSL
auto-EAB with mock servers, URL detection)
- Update docs: README, architecture, connectors, demo-advanced,
testing-guide with EAB/auto-EAB documentation

Standing TXT record at _validation-persist.<domain> eliminates per-renewal
DNS updates. Auto-fallback to dns-01 if CA doesn't offer dns-persist-01.
ScriptDNSSolver extended with PresentPersist method. Configurable via
CERTCTL_ACME_CHALLENGE_TYPE=dns-persist-01 and
CERTCTL_ACME_DNS_PERSIST_ISSUER_DOMAIN env vars.
Also fixes IsExpired edge-case test in discovery_test.go that always failed
due to time.Now() drift between test setup and method invocation.

both PEM and base64-encoded DER CSRs, configurable issuer and profile
binding, full audit trail. 28 new tests (18 handler + 10 service).
Also includes:
- GetCACertPEM added to issuer connector interface (all 4 issuers updated)
- EST integration tests wired into e2e test suite (13 test cases)
- QA testing guide Part 26 (15 manual EST test cases)
- All docs updated: README, features, architecture, concepts, connectors,

M17: Script-based issuer connector delegating sign/revoke/CRL to user-provided
scripts. Compatible with any CA tooling (OpenSSL, cfssl, custom PKI). Configurable
timeout, environment variable passthrough. 14 tests including timeout enforcement.
M16b: certctl-cli wraps all 76 REST API endpoints for terminal workflows. Supports
certs/agents/jobs list/get/renew/revoke/cancel, bulk PEM import with progress
reporting, server health status, table and JSON output formats. Zero external
dependencies (stdlib only). 14 tests with mock HTTP server.

M19: HTTP middleware records every API call to the immutable audit trail
with method, path, actor, SHA-256 body hash, status, and latency. Best-effort
async recording via goroutine. Health/ready probes excluded.
M16a: Four pluggable notifier connectors — Slack (incoming webhook), Teams
(MessageCard), PagerDuty (Events API v2), OpsGenie (Alert API v2). Each
enabled by config env var. 30 new tests across middleware and connectors.

Backend:
- Embedded OCSP responder: GET /api/v1/ocsp/{issuer_id}/{serial} returns
signed OCSP responses (good/revoked/unknown) using CA key
- DER-encoded X.509 CRL: GET /api/v1/crl/{issuer_id} returns proper DER CRL
signed by issuing CA with 24h validity window
- Short-lived cert exemption: certs with profile TTL < 1 hour skip CRL/OCSP
(expiry is sufficient revocation for ephemeral workloads)
- Extended issuer connector interface with GenerateCRL and SignOCSPResponse
- Local CA implements full CRL/OCSP signing; ACME and step-ca return
appropriate "use native endpoint" errors
- IssuerConnectorAdapter bridges new methods between layers
Frontend:
- Revoke button on certificate detail page with RFC 5280 reason modal
- Revocation banner with reason display and timestamp
- Revocation status indicators in lifecycle section
- "Revoked" filter option in certificates list
- API client: revokeCertificate() function and Certificate type extensions
Tests: ~31 new tests across connector, service, handler, and adapter layers
Docs: milestones renumbered (M13-M14, M16-M18), M15b marked complete

Implements core revocation infrastructure: POST /api/v1/certificates/{id}/revoke
with all 8 RFC 5280 reason codes, JSON-formatted CRL at GET /api/v1/crl, webhook
and email revocation notifications, best-effort issuer notification, and immutable
revocation audit trail. Includes 48 new tests across service, handler, integration,
and domain layers (600+ total). Fixes 3 pre-existing test bugs (team_test error
matching, agent_group delete status code, team handler per_page validation).

Sub-CA mode: Local CA loads CA cert+key from disk (CERTCTL_CA_CERT_PATH +
CERTCTL_CA_KEY_PATH) to operate as subordinate CA under enterprise root
(e.g., ADCS). Supports RSA, ECDSA, PKCS#8 keys. Validates IsCA and
KeyUsageCertSign. Falls back to self-signed when paths unset.
DNS-01 challenges: Pluggable DNSSolver interface with script-based hook
implementation. User-provided scripts create/cleanup _acme-challenge TXT
records for any DNS provider. Configurable propagation wait. Enables
wildcard certs and non-HTTP-accessible hosts.
step-ca connector: Smallstep private CA via native /sign API with JWK
provisioner auth. Issuance, renewal, revocation. Registered as iss-stepca.
23 new tests across 3 files. CI test path widened to ./internal/connector/issuer/...

Agents now report OS, architecture, IP address, hostname, and version
via heartbeat using runtime.GOOS, runtime.GOARCH, and net.Dial. New
migration adds columns to agents table. Heartbeat handler, service,
and repository updated to accept and persist metadata. GUI shows
OS/Arch in agent list and full system info in agent detail page.
Apache httpd connector: separate cert/chain/key files, apachectl
configtest validation, graceful reload. HAProxy connector: combined
PEM file (cert+chain+key), optional config validation, reload.
Both wired into agent binary's target connector switch.
14 tests for new connectors. All existing tests updated for new
Heartbeat/UpdateHeartbeat signatures. Docs updated across README,
architecture, concepts, and connectors guides.

- KeyDir permissions enforced with os.Chmod after MkdirAll
- splitPEMChain rewritten to use encoding/pem instead of string parsing

Private keys never leave agent infrastructure. Agents generate ECDSA P-256
key pairs locally, store them with 0600 permissions, and submit only the CSR
(public key) to the control plane. New AwaitingCSR job state pauses
renewal/issuance jobs until the agent submits its CSR. Server-side keygen
retained behind CERTCTL_KEYGEN_MODE=server for demo/development.
Key changes:
- Dual keygen mode via CERTCTL_KEYGEN_MODE (agent default, server for demo)
- AwaitingCSR job state with CommonName/SANs in work response
- Agent ECDSA P-256 keygen, local key storage, CSR-only submission
- CompleteAgentCSRRenewal server-side flow for agent-submitted CSRs
- DeploymentRequest.KeyPEM for agent-provided keys during deployment
- Dockerfile.agent creates /var/lib/certctl/keys with correct ownership
