Platform Floor

9 buckets form the shared backbone. Every other cluster consumes services from here. Grouped into three functional rows: Identity & Access (C1) · Authorization (C2), Persistence (C3, C4, C5, C6), and Platform Services (C7, C8, C12). All three subgroups belong to the Floor — the entire cluster is black; subgroups differ only in border style.

What these buckets cover

Identity & Access — who you are (C1) and what you can do (C2). Gates every request.
Persistence & State — tenant data (C3), encrypted keys/creds (C4), binary blobs (C5), short-lived state + queues (C6). Tenant isolation is a P0 invariant across all four.
Platform Services — transactional email (C7), file-scan gate on all uploads (C8), end-to-end observability with PII scrubbing (C12).
Every downstream module — Policy, Vendor, Risk, Compliance, CSPM, Incidents, everything — consumes from this floor.
Subgroup borders are all Floor-black; they differ only in stroke pattern (solid Identity · long-dash Persistence · short-dash Platform Services). The cluster colour is uniform.
