8. Enter App v4 and SWBPIPE correctly

App v4

Start at the App v4 loop, then the affected deliverable. The App is a workflow-authoring exemplar and a basis for agent functions inside host applications.

Use app/README.md for current build and test entry points. Product role guidance and embedded workflows are separate consumers of Root sources; changes require an applicability assessment and valid source binding, not automatic copying.

The project entry defines scratch Codex homes, credential restrictions, download permissions and thesis protection. This guide does not relax them. An existing documented exception applies only within its actual authorization.

SWBPIPE

Start at the Piping loop, then current ScopeOfWork, Design and needs. The product is an analysis-grade piping design engine and stress-model authoring environment.

The loop carries F-PIP-1–4 and DEC-043. Those project boundaries remain authoritative. This guide does not restate or amend their held wording. In particular, the external corpus's extracted equation artifacts must not become authoritative physics references.

Frozen numerical references live in validation/references/t3_r1/. Their generators and consumers remain maintained. Do not modify reference results to make an implementation pass.

Product operations, professional acceptance and repository development are different activities. Removing development records does not remove a required product event, model history, stop/checkpoint record or user decision.
