Cloud API Runtime

The L1 hwlab-cloud-api runtime is a minimal local HTTP/JSON-RPC service. It does not deploy to DEV or PROD from source tests and does not claim live database persistence unless both DB readiness and the durable runtime adapter readiness are live.

Local Smoke

Run:

node scripts/cloud-api-runtime-smoke.mjs

The smoke starts cmd/hwlab-cloud-api on 127.0.0.1 with an ephemeral port and verifies:

• GET /health reports status: "degraded" when live DB persistence is not connected.
• GET /health reports DB readiness and runtime durable adapter readiness as separate components. A memory adapter remains non-durable even when DB env fields are present.
• The DB contract reports required env names, redacted Secret refs, env injection, connection attempt status, connection result, liveConnected, liveDbEvidence, DNS/TCP/auth/schema readiness layers, and redaction/safety fields without exposing DB URL or secret values.
• gateway.session.register, box.resource.register, box.capability.report, hardware.invoke.shell, audit.event.query, and evidence.record.query round-trip through the same runtime store.
• Shell invoke requests are accepted as recorded cloud operations but report dispatchStatus: "not_connected" until a real gateway shell adapter exists.
• Audit and evidence records use the protocol schema field names.

Persistence Boundary

The default local runtime store is process-local memory:

• runtime.adapter: "memory"
• runtime.durable: false
• runtime.status: "degraded"

This remains the safe local default. DEV can opt into the durable adapter with non-secret env flags:

• HWLAB_CLOUD_RUNTIME_ADAPTER=postgres
• HWLAB_CLOUD_RUNTIME_DURABLE=true

The Postgres adapter uses HWLAB_CLOUD_DB_URL from hwlab-cloud-api-dev-db/database-url; source records only the Secret reference and non-secret DNS contract. The adapter reports runtime.ready: true only after a live schema query proves the required runtime tables and columns exist. If DB auth or schema is missing, /health/live stays degraded and reports a runtime blocker such as runtime_durable_adapter_auth_blocked or runtime_durable_adapter_schema_blocked. Fixture data and env presence are never promoted to runtime.liveRuntimeEvidence.

If HWLAB_CLOUD_DB_URL and HWLAB_CLOUD_DB_SSL_MODE are absent, health reports db.status: "blocked". If both env vars are present, cloud-api attempts a short read-only TCP connection to the DB endpoint from the injected runtime env. The health payload keeps all endpoint details redacted and reports only:

The source-controlled DEV DNS contract for that endpoint is cloud-api-db.hwlab-dev.svc.cluster.local:5432. The actual connection string still comes from hwlab-cloud-api-dev-db/database-url; source records only the non-secret host/service/namespace/port contract. .invalid hosts, including hwlab-dev-db.invalid, are forbidden as DEV runtime targets and may be used only as negative fixtures.

• db.configReady: required env names are present.
• db.connectionAttempted: the runtime tried the live connection path.
• db.connectionResult: redacted classifier such as connected, refused, timeout, dns_error, invalid_url, or unsupported_protocol.
• db.liveConnected: the TCP connection completed.
• db.liveDbEvidence: true only when the live connection completed; env presence, fixtures, and disabled probes must keep this false.
• db.redaction and db.safety: confirm values/endpoints are redacted and secret material was not read by the health path.
• db.readinessLayers: records DNS, TCP, auth, and schema status separately so DNS/TCP repair cannot be confused with authenticated schema readiness.
• db.ready: currently aliases db.liveConnected.

Env presence alone is not treated as green. If the runtime has env injection but db.connectionAttempted is false, db.liveConnected is false, or db.liveDbEvidence is false, the gate must stay blocked/degraded with the reported blocker.

Fixture: fixtures/cloud-api-runtime/minimal-runtime.json.

Code Agent Provider Boundary

hwlab-cloud-api supports OpenAI Responses for the Code Agent chat endpoint. DEV source contracts require OPENAI_API_KEY from Secret hwlab-code-agent-provider/openai-api-key and HWLAB_CODE_AGENT_OPENAI_BASE_URL through the DEV egress/proxy URL. Runtime health and /v1 may report provider status, missing env names, Secret ref names, model, and redacted egress status, but must never print the API key or a Bearer token.
