Builder authority
The builder confirms consequential product and architecture decisions. The model does not quietly become the product owner.
Different starting states. One intent-to-implementation system.
Start before the first build, continue an existing product, control a consequential change, or recover after fidelity has already been lost. Every path resolves the product direction before implementation authority is produced.
Choose the situation, not a different product.
The Case Room adapts the questions and evidence boundary while preserving one authority chain.
What remains constant
Evidence boundaries
Reported intent, supplied artifacts, and repository audit results remain distinguishable instead of being flattened into fake certainty.
Connected outputs
Architecture, blueprint, implementation campaign, and agent sessions inherit from the same confirmed case.
