# Sandbox establishment and lifecycle

Profiles, extensions, provision, checkpoints, TTL teardown and telemetry.

## Reuse boundary

Backend-specific guarantees; a created sandbox alone proves no credential isolation.

## Supported use cases

- U11: Agent executes an attributable bounded task and supplies supervision evidence
- U14: Framework adopter validates and reuses selected contracts, tools and reference compositions

## Evidence and integration

- [SCOPE.md](../../SCOPE.md)
- [README.md](../../README.md)

Assessment: CUST-WP-0081, 2026-10-14. Relations identify interfaces to compose; they do not certify native integration. Existing external evidence levels are retained where present. New entries use conservative C1/R0 until consumer assessment exists.
