Global address planning, interrupt architecture, I/O integration, and hardware/software contract hygiene.
Start with the topic hub to learn the integration contract.
Use mechanism and reports pages to connect contract to metrics.
Use debug and worked-example pages for war-room readiness.
Close with checklist and PPA impact before closure signoff.

Address, interrupt, and IO contracts are where hardware/software alignment is won or lost.
