Merge branch 'fix/m10-openapi-spec-drift': M-10 OpenAPI spec drift reconciliation

Add 9 missing operations to api/openapi.yaml that exist in router.go but
were absent from the spec. Spec-only change with no runtime Go code
changes; all 106 pre-existing operationIds preserved byte-identical.

New operationIds:
  - testTargetConnection (POST /api/v1/targets/{id}/test)
  - verifyDeployment    (POST /api/v1/jobs/{id}/verify)
  - getJobVerification  (GET  /api/v1/jobs/{id}/verification)
  - estCACerts          (GET  /.well-known/est/cacerts)
  - estSimpleEnroll     (POST /.well-known/est/simpleenroll)
  - estSimpleReEnroll   (POST /.well-known/est/simplereenroll)
  - estCSRAttrs         (GET  /.well-known/est/csrattrs)
  - scepGet             (GET  /scep)
  - scepPost            (POST /scep)

Spec operations: 106 → 115 (matches 115 router routes exactly).

Verification:
  - openapi-spec-validator: OK
  - go build ./...: clean
  - go vet ./...:   clean
  - go test -race -count=1 -short ./...: 54 packages ok, 0 FAIL
  - golangci-lint run ./...: 0 issues
  - govulncheck ./...: 0 vulnerabilities in our code
  - tsc --noEmit: 0 errors
  - vitest run: 3 files, 218 tests passed

+            The `certctl-cli` (REST API wrapper) and `certctl-mcp-server` (Model Context
+            Protocol bridge) binaries ship for all four platforms as well:
+
+            - `certctl-cli-{linux,darwin}-{amd64,arm64}`
+            - `certctl-mcp-server-{linux,darwin}-{amd64,arm64}`
+
+            ## 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
+            sha256sum -c checksums.txt
+            ```
+
+            **2. Verify the Cosign signature on checksums.txt (keyless OIDC):**
+
+            ```bash
+            cosign verify-blob \
+              --certificate checksums.txt.pem \
+              --signature checksums.txt.sig \
+              --certificate-identity-regexp '^https://github\.com/shankar0123/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 `.sig` + `.pem` sidecar).
+
+            **3. Verify SLSA Level 3 provenance (binaries):**
+
+            ```bash
+            slsa-verifier verify-artifact \
+              --provenance-path multiple.intoto.jsonl \
+              --source-uri github.com/shankar0123/certctl \
+              --source-tag ${{ steps.version.outputs.VERSION }} \
+              certctl-agent-linux-amd64
+            ```
+
+            **4. Verify container image signature and attestations:**
+
+            ```bash
+            IMAGE=ghcr.io/shankar0123/certctl-server:${{ steps.version.outputs.VERSION }}
+            cosign verify \
+              --certificate-identity-regexp '^https://github\.com/shankar0123/certctl/\.github/workflows/release\.yml@refs/tags/' \
+              --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
+              "$IMAGE"
+
+            # SBOM attestation (SPDX-JSON) emitted by docker/build-push-action
+            cosign verify-attestation --type spdxjson \
+              --certificate-identity-regexp '^https://github\.com/shankar0123/certctl/' \
+              --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \

-## Why certctl Exists
+## Documentation
 
-Certificate lifecycle tooling today falls into two camps: expensive enterprise platforms (Venafi, Keyfactor, Sectigo) that cost six figures and take months to deploy, or single-purpose tools (cert-manager, certbot) that handle one slice of the problem. If you run a mixed infrastructure — some NGINX, some Apache, a few HAProxy nodes, IIS on Windows, maybe an F5 — and you need to manage certificates from multiple CAs, there's nothing self-hosted that covers the full lifecycle without vendor lock-in.
-
-certctl fills that gap. It's **CA-agnostic** — plug in any certificate authority: Let's Encrypt via ACME, Smallstep step-ca, HashiCorp Vault PKI, DigiCert CertCentral, your enterprise ADCS via sub-CA mode, or any custom CA through a shell script adapter. Run multiple issuers simultaneously for different certificate types.
-
-It's **target-agnostic**. Agents deploy certificates to NGINX, Apache, HAProxy, Traefik, Caddy, Envoy, Postfix, Dovecot, IIS (local PowerShell or remote WinRM), F5 BIG-IP (proxy agent), and any Linux/Unix server via SSH/SFTP — all using the same pluggable connector model. The control plane never initiates outbound connections — agents poll for work, which means certctl works behind firewalls, across network zones, and in air-gapped environments.
-
-For a detailed comparison with other competitors and enterprise platforms, see [Why certctl?](docs/why-certctl.md)
-
-## Who Is This For
-
-**Platform engineering and DevOps teams** managing 10–500+ certificates across mixed infrastructure who need automated renewal, deployment, and a single dashboard for visibility. If you're currently running certbot cron jobs, manually renewing certs, or stitching together scripts — certctl replaces all of that.
-
-**Security and compliance teams** who need an immutable audit trail, certificate ownership tracking, policy enforcement, and evidence for SOC 2, PCI-DSS 4.0, or NIST SP 800-57 audits.
-
-**Small teams without enterprise budgets** who need the lifecycle automation that Venafi and Keyfactor provide but can't justify six-figure licensing for a 50-server environment.
-
-## What It Does
-
-- **Certificates renew and deploy themselves.** The scheduler monitors expiration, creates renewal jobs, issues certificates through your CA, and deploys them to target servers — all without human intervention. ACME ARI (RFC 9773) lets your CA tell certctl exactly when to renew. Ready for 45-day and 6-day certificate lifetimes (SC-081v3 and Let's Encrypt shortlived profiles).
-
-- **You see everything in one place.** The operational dashboard shows every certificate across every server: status, ownership, expiration timeline, deployment history with TLS verification, discovery triage, and real-time agent fleet health. Bulk operations (renew, revoke, reassign) work across selections.
-
-- **Private keys never leave your servers.** Agents generate ECDSA P-256 keys locally and submit only the CSR. The control plane never touches private keys. Post-deployment TLS verification confirms the right certificate is actually being served.
-
-- **Discover what you don't know about.** Agents scan filesystems for existing PEM/DER certificates. The network scanner probes TLS endpoints across CIDR ranges without requiring agents. Both feed into a triage workflow where you claim, dismiss, or import discovered certificates.
-
-- **Everything is auditable.** Immutable append-only audit trail records every lifecycle action, every API call, and every approval decision. Certificate digest emails deliver daily briefings. Prometheus metrics endpoint for Grafana dashboards.
-
-- **Multiple interfaces for different workflows.** REST API for automation, CLI for scripting, MCP server for AI assistants (Claude, Cursor, Windsurf), EST server (RFC 7030) for device enrollment, Helm chart for Kubernetes, and the web dashboard for day-to-day operations.

+## Why certctl
+
+Certificate lifecycle tooling falls into two camps: enterprise platforms (Venafi, Keyfactor) that cost six figures and take months to deploy, or single-purpose tools (certbot, cert-manager) that handle one slice of the problem. certctl fills the gap — full lifecycle automation, self-hosted, free, CA-agnostic, and target-agnostic. If you're running certbot cron jobs, manually renewing certs, or stitching together scripts across mixed infrastructure, certctl replaces all of that.
+
+Built for **platform engineering and DevOps teams** managing 10–500+ certificates, **security and compliance teams** who need audit trails and policy enforcement for SOC 2, PCI-DSS 4.0, or NIST SP 800-57 ([compliance mapping included](docs/compliance.md)), and **small teams without enterprise budgets** who need Venafi-grade automation for a 50-server environment. For a detailed comparison, see [Why certctl?](docs/why-certctl.md)
+
+**Architecture.** Go 1.25 control plane with handler→service→repository layering, PostgreSQL 16 backend (21 tables), and a pull-only deployment model — the server never initiates outbound connections. Agents poll for work. 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). Background scheduler runs 7 loops: renewal with ARI integration (1h), job processing (30s), agent health (2m), notifications (1m), short-lived cert expiry (30s), network scanning (6h), certificate digest (24h). See [Architecture Guide](docs/architecture.md) for full system diagrams.
+
+**Security-first.** Agents generate ECDSA P-256 keys locally — private keys never touch the control plane. 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. Atomic idempotency guards on scheduler loops. Issuer and target credentials encrypted at rest with AES-256-GCM. 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.
+
+**Key design decisions.** TEXT primary keys — human-readable prefixed IDs (`mc-api-prod`, `t-platform`, `o-alice`) so you can identify resources at a glance in logs and queries. Idempotent migrations (`IF NOT EXISTS`, `ON CONFLICT DO NOTHING`) safe for repeated execution. Dynamic configuration via GUI with AES-256-GCM encrypted credential storage and env var backward compatibility. Handlers define their own service interfaces for clean dependency inversion.
+
+## What It Does
+
+**Automated lifecycle.** Certificates renew and deploy themselves. The scheduler monitors expiration, issues through your CA, and deploys to targets — zero human intervention. ACME ARI (RFC 9773) lets the CA direct renewal timing. Ready for 47-day (SC-081v3) and 6-day (Let's Encrypt shortlived) certificate lifetimes.
+
+**Operational dashboard.** 26-page GUI covers the entire lifecycle: certificate inventory with bulk ops, deployment timeline with rollback, discovery triage, network scan management, agent fleet health, short-lived credential countdown, approval workflows, and observability metrics. Configure issuers and targets from the dashboard — no env var editing, no server restarts.
+
+**Private keys stay on your servers.** Agents generate ECDSA P-256 keys locally, submit only the CSR. The control plane never touches private keys. After deployment, agents probe the live TLS endpoint and compare SHA-256 fingerprints to confirm the right certificate is actually being served.
+
+**Discovery.** Agents scan filesystems for existing PEM/DER certificates. The network scanner probes TLS endpoints across CIDR ranges without agents. Cloud discovery finds certificates in AWS Secrets Manager, Azure Key Vault, and GCP Secret Manager. Continuous TLS health monitoring tracks endpoint status (healthy/degraded/down/cert_mismatch) with configurable thresholds and historical probe data. All discovery modes feed into a unified triage workflow — claim, dismiss, or import what you find.
+
+**Policy engine.** Certificate profiles constrain key types, max TTL, and EKUs — with crypto policy enforcement that validates every CSR against profile rules before it reaches the issuer. MaxTTL caps are enforced per issuer connector. Approval workflows pause jobs for human review. Ownership tracking routes notifications to the right team. Agent groups match devices by OS, architecture, IP CIDR, and version.
+
+**Enrollment protocols.** EST server (RFC 7030) for device and WiFi enrollment. SCEP server (RFC 8894) for MDM platforms and network devices. S/MIME issuance with email protection EKU.
+
+**Revocation.** Single and bulk revocation (by profile, owner, agent, or issuer). DER-encoded X.509 CRL per issuer, signed by the issuing CA. Embedded OCSP responder. RFC 5280 reason codes. Short-lived certs (TTL < 1 hour) are exempt — expiry is sufficient revocation.
+
+**Audit and observability.** Immutable append-only audit trail records every lifecycle action, every API call, and every approval decision. Prometheus metrics endpoint. Scheduled certificate digest emails. Continuous endpoint health monitoring with state machine transitions and real-time alerts.
+
+**Notifications.** Slack, Teams, PagerDuty, OpsGenie, SMTP, webhooks. Routed by certificate owner. Daily digest emails with stats and expiring certs.
+
+**Multiple interfaces.** REST API (111 routes), CLI (12 commands), MCP server (80 tools for Claude, Cursor, Windsurf), Helm chart, web dashboard. Certificate export in PEM and PKCS#12.
+
+**First-run onboarding.** Wizard guides you through connecting a CA, deploying an agent, and issuing your first certificate. Or start with the pre-populated demo — 32 certificates, 10 issuers, 180 days of history.

+## Verifying this release
+
+Every `v*` tag publishes signed, attested release artefacts. Binaries
+(`certctl-agent`, `certctl-server`, `certctl-cli`, `certctl-mcp-server` for
+`linux|darwin × amd64|arm64`) ship alongside a `checksums.txt`, per-binary
+SPDX-JSON SBOMs, Cosign signatures, and SLSA Level 3 provenance. Container
+images on `ghcr.io/shankar0123/certctl-{server,agent}` are built with
+`docker/build-push-action` `provenance: mode=max` + `sbom: true` and are
+additionally signed with Cosign at the image digest.
+
+All signatures use Cosign keyless OIDC; the signing identity is the
+release workflow running on a signed tag.
+
+**1. Verify SHA-256 checksums:**
+
+```bash
+sha256sum -c checksums.txt
+```
+
+**2. Verify the Cosign signature on `checksums.txt`:**
+
+```bash
+cosign verify-blob \
+  --certificate checksums.txt.pem \
+  --signature checksums.txt.sig \
+  --certificate-identity-regexp '^https://github\.com/shankar0123/certctl/\.github/workflows/release\.yml@refs/tags/' \
+  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
+  checksums.txt
+```
+
+Every individual binary has its own `.sig` + `.pem` sidecar; swap
+`checksums.txt` for any binary name to verify it directly.
+
+**3. Verify SLSA Level 3 provenance on a binary:**
+
+```bash

-## Architecture
-
-**Control plane** (Go 1.25 net/http) → **PostgreSQL 16** (21 tables, TEXT primary keys) → **Agents** (key generation, CSR submission, cert deployment). For Windows servers without a local agent, a proxy agent in the same network zone handles deployment via WinRM. Background scheduler runs 7 loops: renewal checks (1h), job processing (30s), agent health (2m), notifications (1m), short-lived cert expiry (30s), network scanning (6h), certificate digest (24h). See [Architecture Guide](docs/architecture.md) for full system diagrams and data flow.
-
-### Key Design Decisions
-
-- **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.

Agents generate ECDSA P-256 private keys locally, create CSRs, and submit them to the control plane for signing — private keys never leave agent infrastructure. Agents also handle certificate deployment to target systems (NGINX, Apache httpd, HAProxy, Traefik, Caddy, Envoy, Postfix, Dovecot, IIS, F5 BIG-IP, SSH, Windows Certificate Store, Java Keystore) and report job status. They communicate with the control plane via HTTP and authenticate with API keys.

Jobs may be `AwaitingCSR` (agent needs to generate key + submit CSR) or `Deployment` (agent needs to deploy a certificate).

-**Profile enforcement:** If the certificate is assigned to a profile (`certificate_profile_id`), the profile's `allowed_key_algorithms` and `max_validity_days` constraints are checked during CSR validation. A CSR with a disallowed key type or a validity period exceeding the profile maximum is rejected before reaching the issuer connector.
+**Profile enforcement (M11c):** Crypto policy enforcement is wired into all four issuance paths: renewal (server-side and agent CSR), agent fallback CSR signing, EST enrollment (RFC 7030), and SCEP enrollment (RFC 8894). At each path, the service layer resolves the certificate's profile and calls `ValidateCSRAgainstProfile()` to check the CSR key algorithm and minimum key size against the profile's `allowed_key_algorithms` rules. A CSR with a disallowed key type or insufficient key size is rejected before reaching the issuer connector.
+
+**MaxTTL enforcement:** When a profile specifies `max_ttl_seconds`, the value is forwarded through the service-layer `IssuerConnector` interface to the connector layer via `MaxTTLSeconds` on `IssuanceRequest` and `RenewalRequest`. Each issuer connector enforces the cap according to its capabilities: the Local CA caps `NotAfter` directly, Vault overrides its TTL string, step-ca caps `NotAfter` with zero-value handling, and OpenSSL logs an advisory warning (script-based signing can't enforce server-side). For CAs that control validity themselves (ACME, DigiCert, Sectigo, Google CAS, AWS ACM PCA), MaxTTLSeconds passes through but the CA makes the final decision.
+
+**Key metadata persistence:** Certificate versions record `key_algorithm` and `key_size` extracted from the CSR during issuance. This metadata enables post-hoc auditing — operators can verify that all issued certificates comply with the key requirements in effect at the time of issuance.

+#### Bulk Revocation
+
+For compliance events requiring fleet-wide revocation (key compromise, CA distrust, mass decommission), certctl supports bulk revocation by filter criteria. The `POST /api/v1/certificates/bulk-revoke` endpoint accepts filter parameters (profile_id, owner_id, agent_id, issuer_id) and creates individual revocation jobs for each matching certificate. Bulk revocation reuses the same 7-step single-cert flow for each certificate — no new issuer notification or audit mechanics. The operation is idempotent: revoking an already-revoked certificate is a no-op. Partial failures are tolerated — if one certificate fails to revoke (e.g., issuer unavailable), the operation continues for remaining certs and returns a summary. A single `bulk_revocation_initiated` audit event logs the operation with filter criteria, operator actor, and summary (total requested, succeeded, failed counts). Audit events for individual certificate revocations record the operator identity separately. The GUI bulk revoke button on the certificates list filters by visible selections and displays an affected-cert count modal before confirmation.

 **ACME Renewal Information (ARI, RFC 9773):** The ACME connector supports CA-directed renewal timing via the `GetRenewalInfo()` method. Instead of using fixed thresholds (e.g., renew 30 days before expiry), the CA tells certctl when to renew by providing a `suggestedWindow` with start and end times. This is useful for distributing renewal load during maintenance windows and coordinating mass-revocation scenarios. Enable with `CERTCTL_ACME_ARI_ENABLED=true`. Cert ID is computed as `base64url(SHA-256(DER cert))` per RFC 9773. If the CA doesn't support ARI (404 from the ARI endpoint), certctl automatically falls back to threshold-based renewal — no operator intervention required. Errors from the CA are logged as warnings.

+### SCEP Server (RFC 8894)
+
+The SCEP (Simple Certificate Enrollment Protocol) server provides certificate enrollment for MDM platforms and network devices. It runs at `/scep` with operation-based dispatch via query parameters per RFC 8894.
+
+**Architecture:** SCEP follows the exact same layering as EST — a handler-level protocol that delegates certificate issuance to an existing `IssuerConnector`. The `SCEPService` bridges the `SCEPHandler` to whichever issuer connector is configured via `CERTCTL_SCEP_ISSUER_ID`.
+
+```
+Client (MDM, network device, SCEP client)
+    │
+    ▼
+SCEPHandler (handler layer)
+    │  PKCS#7 envelope parsing, CSR extraction, challenge password extraction
+    ▼
+SCEPService (service layer)
+    │  Challenge password validation, 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:** SCEP clients wrap CSRs in PKCS#7 SignedData envelopes. The handler parses the outer ASN.1 ContentInfo → SignedData → EncapsulatedContentInfo to extract the CSR bytes. Fallback paths handle base64-encoded PKCS#7 and raw CSR submissions (for simpler clients). Responses use PKCS#7 certs-only via the shared `internal/pkcs7` package (same as EST). Single certs are returned as raw DER for `GetCACert`, chains as PKCS#7.
+
+**Authentication:** SCEP uses challenge passwords embedded in CSR attributes (OID 1.2.840.113549.1.9.7) rather than TLS client certificates. The server validates the challenge password against `CERTCTL_SCEP_CHALLENGE_PASSWORD`. When no challenge password is configured, any value is accepted.
+
+**Interface:** The `SCEPHandler` defines an `SCEPService` interface (dependency inversion):
+
+```go
+type SCEPService interface {
+    GetCACaps(ctx context.Context) string
+    GetCACert(ctx context.Context) (string, error)
+    PKCSReq(ctx context.Context, csrPEM string, challengePassword string, transactionID string) (*domain.SCEPEnrollResult, error)
+}
+```
+
+**Shared PKCS#7 package:** Both EST and SCEP handlers share a common `internal/pkcs7` package for building PKCS#7 certs-only responses and PEM-to-DER chain conversion, eliminating code duplication between the two enrollment protocols.
+
+**Audit:** Every SCEP enrollment is recorded in the audit trail with `protocol: "SCEP"`, the CN, SANs, issuer ID, serial number, transaction ID, and optional profile ID.

 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.
 
+### Config Encryption at Rest
+
+Dynamic issuer and target configurations (rows with `source='database'`) contain credentials — ACME EAB HMACs, Vault tokens, DigiCert/Sectigo API keys, SSH private keys, WinRM passwords, F5 BIG-IP passwords, and similar. These are sealed at rest in PostgreSQL via `internal/crypto/encryption.go` using AES-256-GCM with a key derived from the operator passphrase `CERTCTL_CONFIG_ENCRYPTION_KEY` through PBKDF2-SHA256 (100,000 rounds, 32-byte output).
+
+**v2 wire format (current, M-8 remediation, CWE-916 / CWE-329):**
+
+```
+magic(0x02) || salt(16) || nonce(12) || ciphertext+tag
+```
+
+Every call to `EncryptIfKeySet` draws 16 fresh bytes from `crypto/rand` as the PBKDF2 salt, so the derived AES-256 key is distinct per ciphertext and per re-encryption. The salt is stored alongside the ciphertext; decryption reads the magic byte, splits out the salt, re-derives the key, and verifies the AEAD tag.
+
+**v1 legacy format (read-only):**
+
+```
+nonce(12) || ciphertext+tag
+```
+
+Pre-M-8 blobs were sealed with a package-level fixed salt `"certctl-config-encryption-v1"`. `DecryptIfKeySet` preserves the v1 read path unchanged — a blob whose first byte is not `0x02`, or whose v2 AEAD verification fails (including the 1/256 case where a v1 nonce happens to begin with `0x02`), falls through to a v1 attempt against the legacy fixed salt. v1 blobs are never written by the post-M-8 code path; they re-seal as v2 naturally on the next UPDATE through the normal service CRUD flow. No operator migration ceremony is required.
+
+**Fail-closed behavior (C-2 sentinel, CWE-311):** both `EncryptIfKeySet` and `DecryptIfKeySet` return `ErrEncryptionKeyRequired` when invoked with an empty passphrase. The server refuses to start if any `source='database'` rows already exist without `CERTCTL_CONFIG_ENCRYPTION_KEY` set.
+
+**Low-level primitives preserved byte-identical.** `Encrypt`, `Decrypt`, and `DeriveKey` are kept bit-stable so v1 fixtures on disk remain decryptable unchanged and so callers outside the config-encryption path (none today, but the symbols are exported) do not see a breaking change. The new per-ciphertext salt path is reached via the helper `deriveKeyWithSalt(passphrase, salt)`.
+
+**Passphrase plumbing.** Services (`IssuerService`, `TargetService`, `IssuerRegistry`) hold the operator passphrase as a raw `string` and delegate PBKDF2 to the crypto package per ciphertext. This replaces the pre-M-8 design that pre-derived a single `[]byte` key at service construction and reused it for every row, which was the direct consequence of the fixed-salt KDF.
+
+**Coverage gate.** CI enforces `internal/crypto/...` coverage ≥ 85% (observed 86.7%) — the encryption primitives are a security-critical gate, and the v2 format plus v1 fallback plus C-2 sentinel paths all need exhaustive coverage to avoid silent regressions.

 ### 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.

+## Continuous TLS Health Monitoring (M48)
+
+Beyond one-time discovery, certctl continuously monitors TLS endpoints for certificate health using a shared TLS probing package and a state-machine-driven health check service. Endpoints transition between states (Healthy → Degraded → Down) based on consecutive failures, and `cert_mismatch` status alerts when a deployed certificate is unexpectedly replaced.
+
+**Architecture:** Probing is extracted into a shared `internal/tlsprobe/` package used by both the network scanner (M21) and the health monitor. The `HealthCheckService` manages 8 API endpoints for CRUD operations and state transitions. A dedicated 8th scheduler loop runs every 60 seconds (configurable via `CERTCTL_HEALTH_CHECK_INTERVAL`). Individual health check targets have their own check intervals (default 300 seconds) — the scheduler queries only endpoints due for check via `ListDueForCheck()`. Results are stored with historical tracking for 30 days (configurable via `CERTCTL_HEALTH_CHECK_HISTORY_RETENTION`). State transitions trigger notifications (critical for down endpoints, warning for degraded, high for cert_mismatch).
+
+**State Machine:** Healthy → Degraded (configurable threshold, default 2 consecutive failures) → Down (default 5 failures). The `cert_mismatch` status is special — it fires whenever the observed certificate fingerprint differs from the expected (deployed) fingerprint, catching silent rollbacks and unauthorized cert replacements. Recovery from degraded/down transitions back to healthy and resets the failure counter.
+
+**API:** 8 endpoints for list (with filters: status, certificate_id, network_scan_target_id, enabled), get, create, update, delete, history (with limit param), acknowledge (incident marking), and summary (aggregate status counts).
+
+**Auto-Create:** When a deployment job completes with successful verification (M25), the system automatically creates a health check with the deployed certificate's fingerprint as the expected value. Network scan targets can also opt-in to auto-create health checks for discovered endpoints.
+
+**Configuration:**
+

+|---|---|---|
+| `CERTCTL_HEALTH_CHECK_ENABLED` | `false` | Enable/disable the feature |
+| `CERTCTL_HEALTH_CHECK_INTERVAL` | `60s` | Scheduler tick interval |

 **Revocation API**: `POST /api/v1/certificates/{id}/revoke` marks a certificate as revoked in the inventory, records the revocation in a dedicated `certificate_revocations` table, notifies the issuing CA (best-effort — the revocation succeeds even if the CA is unreachable), creates an audit trail entry, and sends notifications. You can specify an RFC 5280 reason code (keyCompromise, superseded, cessationOfOperation, etc.) or let it default to "unspecified."
 
+**Bulk Revocation** (Fleet-Level Incident Response): For large-scale incidents like CA compromise or team infrastructure decommissioning, `POST /api/v1/certificates/bulk-revoke` revokes all certificates matching filter criteria in a single operation. Filter by profile, owner, team, agent group, or issuer to target the affected certificate set. This is essential for incident response — instead of revoking certificates one-by-one, operators can revoke an entire fleet in minutes. Bulk revocation creates individual revocation jobs that reuse the existing revocation pipeline, ensuring every certificate is audited and notifications are sent.
+
 **Certificate Revocation List (CRL)**: certctl serves both a JSON-formatted CRL at `GET /api/v1/crl` and DER-encoded X.509 CRLs per issuer at `GET /api/v1/crl/{issuer_id}`. The DER CRL is signed by the issuing CA's key and has 24-hour validity — clients can download it periodically to check revocation status offline.
 
 **OCSP Responder**: For real-time revocation checking, certctl includes an embedded OCSP responder at `GET /api/v1/ocsp/{issuer_id}/{serial}`. It returns signed OCSP responses (good, revoked, or unknown) so clients can verify certificate status without downloading the full CRL.

-Note: ADCS (Active Directory Certificate Services) integration is handled via the **sub-CA mode** of the Local CA issuer, not as a separate connector. certctl operates as a subordinate CA with its signing certificate issued by ADCS, so all certctl-issued certs chain to the enterprise ADCS root. See the Local CA section above.
+**Authentication:** Mutual TLS — the client certificate and key are loaded via `tls.LoadX509KeyPair()` and attached to the HTTP transport. No API key or token required.
+
+**Issuance model:** Enrollment via `POST /v1/certificate-authorities/{caId}/enrollments`. Returns 200 with PEM immediately for auto-approved enrollments, or 201 Accepted with a tracking ID for approval-pending orders. `GetOrderStatus` polls the enrollment endpoint.
+

+
+**Authentication:** Dual — mTLS client certificate for TLS handshake plus `X-API-Key` and `X-API-Secret` headers on every request.
+
+**TLS verification:** The connector always verifies the server certificate. When `server_ca_path` is set, the PEM bundle at that path is used as the trust anchor; otherwise the host's system trust store is used. TLS 1.2 is the minimum protocol version.
+

+// Package awssm implements the domain.DiscoverySource interface for AWS Secrets Manager.
+//
+// AWS Secrets Manager is a managed service for storing and managing secrets including
+// certificates. This discovery source scans Secrets Manager for certificates stored
+// as secrets, filters by configured tags and name prefix, and reports discovered
+// certificate metadata back to the control plane for triage and management.
+//
+// Discovery approach:
+// 1. List all secrets in the configured region
+// 2. Filter by tag key=value (default "type=certificate")
+// 3. Optionally filter by name prefix
+// 4. For each secret, retrieve its value
+// 5. Attempt to parse as PEM or base64-encoded DER
+// 6. Extract certificate metadata (CN, SANs, serial, validity, etc.)
+// 7. Report findings with sentinel agent ID "cloud-aws-sm" and source path "aws-sm://{region}/{secret-name}"
+//
+// Authentication: AWS credentials via standard credential chain (environment variables,
+// IAM roles, instance profile, SSO). The caller is responsible for configuring AWS credentials
+// before creating a Source (e.g., via environment variables AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY).
+//
+// AWS Secrets Manager API operations used:
+//
+//	ListSecrets - List secrets, optionally filtered by tags
+//	GetSecretValue - Retrieve the secret value (certificate data)

+// Package gcpsm implements the domain.DiscoverySource interface for GCP Secret Manager.
+//
+// GCP Secret Manager is a Google Cloud service for securely storing and managing secrets,
+// including certificates. This discovery source scans Secret Manager for certificates stored
+// as secrets, filters by configured tags, and reports discovered certificate metadata
+// back to the control plane for triage and management.
+//
+// Discovery approach:
+// 1. Authenticate using service account JSON credentials (JWT → OAuth2 token exchange)
+// 2. List all secrets in the configured GCP project
+// 3. Filter by label "type=certificate"
+// 4. For each secret, retrieve the latest version's data
+// 5. Base64-decode the secret value, then attempt PEM or DER parsing
+// 6. Extract certificate metadata (CN, SANs, serial, validity, key algorithm, etc.)
+// 7. Report findings with sentinel agent ID "cloud-gcp-sm" and source path "gcp-sm://{project}/{secret-name}"
+//
+// Authentication: OAuth2 service account via JWT assertion. The service account
+// credentials must be provided in a JSON file. The connector loads the private key,
+// builds a JWT, exchanges it for an access token, then uses Bearer token auth for
+// all subsequent Secret Manager API calls.
+//
+// GCP Secret Manager API operations used:
+//
+//	GET /v1/projects/{project}/secrets - List secrets with filtering
+//	GET /v1/projects/{project}/secrets/{name}/versions/latest:access - Access secret data

+// Package entrust implements the issuer.Connector interface for Entrust Certificate Services.
+//
+// Entrust Certificate Services provides enterprise certificate authority offerings via
+// the Entrust CA Gateway REST API. Unlike synchronous issuers (Vault, step-ca), Entrust
+// uses an asynchronous order model: submit an enrollment, receive a tracking ID, then
+// poll for completion. This connector maps to certctl's existing job state machine:
+//   - IssueCertificate submits the enrollment; if status is "ISSUED", returns cert immediately.
+//     If status is pending, returns OrderID with empty CertPEM — the job system polls
+//     via GetOrderStatus.
+//   - GetOrderStatus polls the enrollment; when status becomes "ISSUED", returns the cert.
+//
+// Authentication: mTLS client certificate loaded from disk (X509 key pair).
+// No API key header — uses mutual TLS authentication at the transport layer.
+//
+// Entrust CA Gateway REST API used:
+//
+//	POST /v1/certificate-authorities/{caId}/enrollments                - Submit enrollment
+//	GET  /v1/certificate-authorities/{caId}/enrollments/{trackingId}  - Check enrollment status
+//	PUT  /v1/certificate-authorities/{caId}/certificates/{serial}/revoke - Revoke certificate
+//	GET  /v1/certificate-authorities/{caId}                            - Validate CA access

+// Package globalsign implements the issuer.Connector interface for GlobalSign Atlas HVCA.
+//
+// GlobalSign Atlas HVCA (Hosted Validation CA) is an enterprise certificate authority
+// offering DV and OV certificates. Unlike synchronous issuers (Vault, step-ca), GlobalSign
+// uses an asynchronous order model with serial number polling: submit a certificate order,
+// receive a serial number immediately, then poll to check when the cert is available.
+//
+// This connector maps to certctl's existing job state machine:
+//   - IssueCertificate submits the order and returns the serial number. The cert PEM
+//     is typically available within seconds for DV certs.
+//   - GetOrderStatus polls via the serial number to retrieve the cert when ready.
+//
+// Authentication: mTLS client certificate (mutual TLS handshake) PLUS API key/secret
+// headers on every request. This is a "double auth" pattern.
+//   - TLS client certificate: loaded from disk via tls.LoadX509KeyPair()
+//   - API key/secret: sent as custom HTTP headers (ApiKey, ApiSecret)
+//
+// GlobalSign Atlas HVCA API used:
+//
+//	POST /v2/certificates           - Submit certificate order, returns serial number
+//	GET  /v2/certificates/{serial}  - Get certificate PEM by serial number
+//	PUT  /v2/certificates/{serial}/revoke - Revoke certificate (no reason code required)
+//	GET  /v2/certificates           - List certificates (for config validation)
