Posture export to control towers
Posture export (modules/posture-export) is the engine’s outbound posture
surface: a single read-only endpoint a control tower polls to enrich its own
inventory with the engine’s ground-truth access graph,
least-privilege drift, discovered inventory and security posture. It is the
“integrate, not compete” side of the platform — it never emits identity (that is
inbound, owned by governance), only
posture, and it changes nothing.
What it exposes
Section titled “What it exposes”One route, GET /v1/m/posture/export, gated by posture:export:read and pinned
to a single tenant scope. The response is a neutral JSON document assembled
inside one audited transaction with three projections:
inventory— active discovered entities (kind, ref, status, signal sources, hosts, first/last seen, occurrence count), optionally filtered by?kind=.posture_drift— the reconciled least-privilege drift: observed-but-not- permitted accesses, plus unused-grant and inventory-grant counts.findings— security findings projected as refs and adetail_hashonly, filterable by?severity=floor and?category=.
Every export is minimal-data — refs, hashes and relations only, never a raw payload or secret — and a defensive redact pass scrubs every free-form field. The export itself moves data off-box, so it self-audits to the ledger with the real principal in the same transaction as the reads.
Maturity and bounded context
Section titled “Maturity and bounded context”PARTIAL. The export action is live and audited; what is not verified is the other end. The ingest formats of the named towers — Microsoft Agent 365 and ServiceNow AI Control Tower — have no primary-source API the engine could validate against, so this is an honest neutral-JSON projection a tower pulls (or an operator routes through a configured sink), explicitly NOT a working native push. Each response carries that provenance note inline.
Per-request caps bound inventory, drift and findings; a partial export reports its own truncation flags and is never labelled authoritative.
