Platform
Every headline stage passes on every core estate against the pinned emulator, and two estates have run on a real account.
Every resource this fork manages carries two tags, tofu-estate and tofu-address, written on the create call. The tags are the identity the next plan binds to and the attribute your IAM conditions on. Everything else is stock OpenTofu.
Everything on these five pages links down into the evidence: the runnable claims, the gauntlet, the measurements, and the per-type lookup.
