BSR-ready submission workflow
Threadsovereign prepares and validates structured submission packages against BSR checklist requirements before export. Duty-holders submit via the BSR portal; correspondence, manual portal references, and submission audit trails are captured in-platform. This pre-validation workflow reduces incomplete Gateway submissions and maintains a BSR-ready golden thread data model throughout the building lifecycle.
Data separation
Each organisation's data is tenant-isolated with row-level security. Operator views serve duty-holders and Accountable Persons; any regulator-facing data sharing would be governed by explicit contractual terms and user disclosure — operator tenant data is never shared without authorisation.
Quality assurance
The platform is validated by 966+ automated unit tests, comprehensive BSA end-to-end test suites, and an evidence integrity scan across statutory workflows. Gateway transitions, resident request idempotency, KBI validation, and occurrence deadline enforcement are covered by dedicated test specifications.
