Ownership, and Making This Template Your Own (Part 5)

Part 4 covered how this platform actually ships — scaffolding, CI/CD, and the two deployment shapes. This closing part is the two things every one of the last four parts has assumed: who actually owns each piece of this, and what it takes to make this whole template yours. Who owns what Every piece of this platform belongs to exactly one team, and that split is what makes independent deploys survive contact with a real organization, not just a single-team demo: Piece Owned by Depends on Host / Shell Platform team Store, Components, the manifest, the identity provider Components MFE Platform / design-systems team Nothing (a leaf) Store MFE Platform team The identity provider Utilities MFE Platform team Nothing (a leaf) Domain MFE (×N) Domain team Components, Store, Utilities only Manifest Registry Platform team Nothing Identity provider(s) Outside the platform — whichever the deployment configures — Backend / BFF Domain team, or a shared gateway (Part 2) Each team's own data The rule underneath the table: domain teams never import from each other, only from the shared platform layer. That keeps the dependency graph a strict two-level tree — Host → platform layer → domain leaves — instead of a mesh, which is what keeps independent deployability tractable once there's more than a handful of domain teams. It's the same rule that made every part of this series possible to write in isolation: Part 3's auth flow doesn't need to know Part 4's deploy pipeline exists, and neither needs to know how many domain teams there eventually are. Making this template your own Everything organization-specific in this platform — branding, which identity provider(s) it trusts, where the manifest lives — has lived in one file across this entire series, on purpose: // platform.config.json { "orgName" : "acme-corp" , "branding" : { "primaryColor" : "#0B5FFF" , "logoUrl" : "..." }, "idp" : { "issuers" : [ { "id" : "primary" , "issuer" : "https://issuer.example.com" , "clientId" : "..." , "def
