# Architecture specs For the integrated product sprint, read [SPRINT.md](../../SPRINT.md) first. The owner approves the proposed decisions together with the concrete nightly plan; preparation alone does not authorize implementation. Detailed references still define data/trust boundaries, failure recovery, migrations, and deterministic acceptance. They do not create a second freeze queue for an approved sprint. ## Detailed references - [Data model](data-model.md): the reviewed table contracts, proposed D1-D7 defaults, and 22 falsifiable acceptance cases adopted by an approved sprint.
