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

Host / Shell
Platform team
Store, Components, the manifest, the identity provider
Components MFE
Platform / design-systems team
Nothing (a leaf)

The identity provider

Outside the platform — whichever the deployment configures
