C-001 — CreateCertificate was server-accepted with null owner_id,
team_id, renewal_policy_id because the GUI neither collected the fields
nor enforced them, even though the backend's ManagedCertificate schema
and handler contract treat them as required. Fix the contract at all
four layers:
- web/src/pages/CertificatesPage.tsx: replace owner_id/team_id free-
text inputs with <select> elements fed by getOwners/getTeams/
getPolicies queries; mark all three required; gate the Create
button on owner_id + team_id + renewal_policy_id being set.
- internal/api/handler/certificates.go: ValidateRequired for
owner_id, team_id, renewal_policy_id on CreateCertificate so the
handler returns HTTP 400 with the offending field name before the
service layer is reached.
- internal/mcp/types.go: drop ',omitempty' from
CreateCertificateInput.RenewalPolicyID so the MCP schema reflects
the required contract; Update inputs keep partial-update semantics.
- api/openapi.yaml: 'required: [name, common_name, renewal_policy_id,
issuer_id, owner_id, team_id]' was already present on the Create
schema; clarified DeploymentTarget.agent_id description to note the
FK contract.
C-002 — CreateTargetWizard accepted an empty or bogus agent_id and the
service inserted directly, producing a Postgres 23503 FK-violation that
bubbled out as a generic HTTP 500. The FK itself (migration 000001 line
104: agent_id TEXT NOT NULL REFERENCES agents(id)) is correct; we keep
the schema strict and add validation at three layers:
- internal/service/target.go: introduce
ErrAgentNotFound sentinel and pre-validate agent_id in
TargetService.CreateTarget — empty string returns
'agent_id is required'; a nonexistent id returns the full
'referenced agent does not exist: <id>' error. Both wrap
ErrAgentNotFound via fmt.Errorf %w so callers can use errors.Is.
- internal/api/handler/targets.go: ValidateRequired on agent_id; map
errors.Is(err, service.ErrAgentNotFound) to HTTP 400 instead of
letting it fall through to the generic 500 branch.
- internal/mcp/types.go: drop ',omitempty' from
CreateTargetInput.AgentID to match the required contract.
- web/src/pages/TargetsPage.tsx: replace the free-text Agent ID input
with a <select> populated from getAgents(); include agent in the
canProceedToReview gate so Next is disabled until an agent is
chosen.
Regression coverage (21 new subtests total):
- TestCreateCertificate_MissingRequiredField_Returns400 — 6 subtests,
one per required field, each proves the handler guard fires before
the mock service is called.
- TestCreateTarget_MissingAgentID_Returns400 — handler guard.
- TestCreateTarget_NonexistentAgent_Returns400 — pins the
ErrAgentNotFound -> 400 translation.
- TestTargetService_CreateTarget_MissingAgentID — errors.Is sentinel.
- TestTargetService_CreateTarget_NonexistentAgentID — errors.Is.
- The existing TestTargetService_CreateTarget_Success, along with
TestCreateTarget_{MissingName,MissingType,NameTooLong}_* handler
tests, were updated to seed a real agent or include agent_id in
the request body so the happy paths still run cleanly.
Gates (Phase 4):
- go build/vet/test/race: green
- go test -cover: internal/service 68.7% (gate 55%),
internal/api/handler 78.9% (gate 60%)
- golangci-lint on service+handler+mcp: 0 issues
- govulncheck: no reachable vulns
- tsc --noEmit: clean
- vitest: 223/223 passing

Mirror M34's dynamic issuer config pattern for deployment targets: AES-256-GCM
encrypted config storage, sensitive field redaction in API responses, agent
heartbeat-based test connection endpoint, and full frontend updates including
test status indicators, source badges, and removal of stale hostname/status
fields from the Target interface.

Backend hardening:
- Fix 6 nginx.go non-constant format string build errors
- Add validation.go with hostname, PEM, and enum validators
- Apply input validation to all POST/PUT handlers (certificates,
agents, CSR, policies, teams, owners, targets, issuers)
- Fix unchecked JSON decode in TriggerDeployment handler
Frontend (Vite + React + TypeScript):
- Migrate from single-file SPA to proper build pipeline
- 7 pages: Dashboard, Certificates (list+detail), Agents, Jobs,
Notifications, Policies, Audit Trail
- TanStack Query for server state with auto-refetch intervals
- Certificate detail with version history and renewal trigger
- Job cancellation, status/type filtering, expiry countdowns
- Reusable components: DataTable, StatusBadge, ErrorState, PageHeader
- Dark theme with Tailwind CSS, sidebar nav via React Router
Server integration:
- Go server serves web/dist/ (Vite output) with SPA fallback
- Falls back to web/index.html for legacy mode
- .gitignore updated for web/node_modules/ and web/dist/
