PR-E of 6 in the M-2 end-to-end remediation sequence. Collapses the
HeartbeatWithContext wrapper into a single ctx-first Heartbeat method,
matching D-1 (ctx-only signatures, no dual forms). The handler-facing
method name is preserved (D-4) — internal/api/handler/agents.go already
declares `Heartbeat(ctx, ...)` on its local service interface, and the
handler mock at internal/api/handler/agent_handler_test.go already
takes `_ context.Context` as its first param, so no handler churn.
Changes
-------
internal/service/agent.go
- Delete the zero-body Heartbeat wrapper that forwarded to
HeartbeatWithContext with context.Background().
- Rename HeartbeatWithContext → Heartbeat (ctx-bearing body
folded directly into the canonical method).
internal/service/agent_test.go
- TestHeartbeat (L95) and TestHeartbeat_NotFound (L128):
agentService.HeartbeatWithContext(ctx, ...) → .Heartbeat(ctx, ...).
internal/service/concurrent_test.go
- L162: agentSvc.HeartbeatWithContext(ctx, agentID, metadata)
→ .Heartbeat(ctx, agentID, metadata).
internal/service/context_test.go
- L179 + L232: agentSvc.HeartbeatWithContext(ctx, ...) → .Heartbeat(...)
- L185 + L238 t.Logf strings: "HeartbeatWithContext with ..." →
"Heartbeat with ..." to match the collapsed method name.

Audit complete. Commit: 1f6cf0eafa. Sections: 12. Findings: 2/7/10/4/6.
Fixes H-6 (CWE-362) — GetPendingJobs returned pending rows without row
locks, so two scheduler replicas in an HA deployment could both read the
same row, both decide it was theirs, and race on UpdateStatus, producing
duplicate Running jobs and duplicate certificate issuances.
Remediation: a claim-style repository API that selects + transitions
Pending -> Running in one transaction with SELECT ... FOR UPDATE SKIP
LOCKED. Concurrent claimants observe disjoint row sets; no worker ever
sees another worker's claimed row.
Repository changes (internal/repository/postgres/job.go):
- New ClaimPendingJobs(ctx, jobType, limit): BEGIN; SELECT id,...
FROM jobs WHERE status='Pending' (optional type filter, optional
LIMIT) FOR UPDATE SKIP LOCKED; UPDATE jobs SET status='Running',
updated_at=NOW() WHERE id = ANY($ids); COMMIT. Returns the claimed
rows with status already flipped.
- New ClaimPendingByAgentID(ctx, agentID): mirrors M31 UNION ALL
semantics (direct agent_id match, target->agent JOIN fallback,
certificate->target->agent chain for AwaitingCSR) but wraps each
branch in FOR UPDATE SKIP LOCKED and flips Deployment/Renewal rows
to Running. AwaitingCSR rows are returned in place (state
transition deferred until SubmitCSR, consistent with M8 semantics).
- Existing GetPendingJobs / ListPendingByAgentID retained for legacy
compatibility; their godoc now directs production callers to the
Claim* variants.
Production caller switches:
- internal/service/job.go ProcessPendingJobs: ListByStatus(Pending)
-> ClaimPendingJobs(ctx, "", 0). Eliminates the real scheduler
race between two replicas tick-firing simultaneously.
- internal/service/agent.go GetPendingWork: ListPendingByAgentID ->
ClaimPendingByAgentID. Eliminates the race between two pollers
for the same agent (e.g. brief network blip causing duplicate
poll) and between a scheduler tick and an agent poll.
Safety argument for pre-flipping Pending -> Running inside the claim
transaction: ProcessRenewalJob and ProcessDeploymentJob both call
UpdateStatus(Running) unconditionally on entry, so an early flip is
idempotent. On panic, the scheduler's panic recovery leaves the job
in Running which the existing stale-running reaper handles.
Tests (internal/repository/postgres/repo_test.go, skipped in -short):
- TestJobRepository_ClaimPendingJobs_FlipsToRunning: seed 5 Pending,
claim once, assert all 5 returned + DB rows Running, residual
claim returns 0.
- TestJobRepository_ClaimPendingJobs_ConcurrentDisjoint: seed M=40
Pending Renewals, spawn N=8 goroutines each calling
ClaimPendingJobs(_, JobTypeRenewal, 1) in a loop. Invariants:
(a) no job ID claimed by more than one worker, (b) sum of claims
== 40, (c) all 40 rows in Running state in the DB. Bounded
empty-streak guard (20 iterations) covers SKIP LOCKED transient
zeros under contention.
- TestJobRepository_ClaimPendingByAgentID_TransitionsDeployments:
seeds 2 Pending Deployment + 1 AwaitingCSR for agent A plus 1
Pending Renewal for agent B (scope check). Asserts deployments
flip to Running, AwaitingCSR is returned but preserved, agent B's
renewal never appears.
Mock updates: testutil_test.go, lifecycle_test.go, verification_test.go
gained ClaimPendingJobs/ClaimPendingByAgentID on their mock job repos
mirroring the real Pending -> Running semantics. Mocks intentionally
do NOT write to StatusUpdates (that map tracks UpdateStatus() call
history specifically; the real claim path uses a bulk UPDATE, not
UpdateStatus).

Replaces math/rand-based agent API key generation in internal/service/agent.go
with crypto/rand.Read over a 32-byte buffer encoded with base64.RawURLEncoding,
yielding a 43-character URL-safe unpadded ASCII string (256 bits of entropy).
generateAPIKey now returns (string, error); Register and RegisterAgent propagate
entropy-source failures. hashAPIKey is unchanged — the SHA-256 hashed-at-rest
invariant is preserved.
Fixes C-1 (CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator)
from certctl-audit-report.md.
Changes:
- internal/service/agent.go: new imports (crypto/rand, encoding/base64);
generateAPIKey rewritten to return (string, error); Register and RegisterAgent
updated to propagate the error.
- internal/service/agent_test.go: TestGenerateAPIKey_Properties regression test
(non-empty, length 43, valid base64url, 32 decoded bytes, no collisions over
64 calls). No entropy-failure test — Go 1.24+ (issue #66821) makes crypto/rand
errors fatal, so that branch is defensively unreachable.
Verification:
- go build ./cmd/server/... ./cmd/agent/... ./cmd/mcp-server/... ./cmd/cli/... → pass
- go vet ./... → pass
- go test -race (CI scope, 43 packages) → pass
- golangci-lint v2.11.4 run ./... → 0 issues
- govulncheck ./... → 0 vulnerabilities in certctl code
- Coverage: service 68.9% / handler 83.6% / domain 82.0% / middleware 63.8%
(all above CI gates 55/60/40/30)
- grep math/rand in internal/ and cmd/ → zero production hits
- No caller assumes the old 32-char length or legacy charset
Enforce certificate profile crypto constraints across all 5 issuance paths
(renewal, agent CSR, EST, SCEP). ValidateCSRAgainstProfile() rejects CSRs
with key algorithm/size that don't match profile rules. MaxTTL enforcement
caps certificate validity per issuer connector (Local CA, Vault, step-ca
enforce directly; ACME/DigiCert/Sectigo pass through). Key algorithm and
size are now persisted in certificate_versions for audit compliance.
16 new tests (12 service-layer + 4 Local CA connector). Removes hardcoded
version number from GUI sidebar. Documentation updated across architecture,
features, connectors, and README.

Replace static env-var-based issuer wiring with GUI-driven dynamic
configuration stored encrypted in PostgreSQL. Operators can now
configure, test, enable/disable, and manage issuers from the dashboard
without restarting the server.
Key changes:
- AES-256-GCM encryption for sensitive issuer config at rest (PBKDF2
key derivation with 100k iterations)
- Dynamic IssuerRegistry with sync.RWMutex replacing static map
- Connector factory pattern (issuerfactory.NewFromConfig) replacing
140 lines of static wiring in main.go
- Migration 000009: encrypted_config, last_tested_at, test_status,
source columns on issuers table
- Env var seeding on first boot with ON CONFLICT DO NOTHING
- Registry Rebuild() for atomic map swap after CRUD operations
- Issuer type validation against domain constants on Create
- Audit trail for test connection results
- Conditional seeding for step-ca/OpenSSL (only when env vars set)
- GUI: source badge, connection test status on issuer detail page

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.

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.

All 10 service files now use slog.Error for failure logging instead of
fmt.Printf. Audit event recording errors are checked and logged rather
than silently discarded. Adds consistent structured context (resource IDs,
operation names) to all error log statements.

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
