verified-interface-controls-bidirectional-flow
OUT derived (depth 8)
All information flowing through the system's verified, fault-tolerant user interface is controlled in both directions: inbound through production-hardened LLM integration with bounded execution and fail-soft semantics, outbound through deterministic authorized access-controlled output — the verified interface serves as a trustworthy gateway that neither admits uncontrolled inputs nor emits unauthorized outputs.
Summary
The system's user interface acts as a fully controlled gateway — nothing gets in without going through hardened, failure-safe processing, and nothing gets out without explicit authorization. This belief is currently marked OUT, meaning one or both of its supporting claims (that information flow is controlled bidirectionally, or that the user interface is verified and fault-tolerant) have been retracted or lost support, so this stronger combined guarantee does not currently hold.
Justifications
SL — Bidirectional information control + verified fault-tolerant interface means the user-facing surface is a fully controlled gateway
Antecedents (all must be IN):
- information-flow-is-controlled-in-both-directions — Information flow is controlled at every system boundary: inbound data passes through production-hardened LLM integration (bounded execution, fail-soft handling, process isolation) and boundary-controlled information isolation (access tags, namespace partitioning), while outbound data is deterministic, authorized via transitive subset-gated access control, and budget-constrained — no uncontrolled data enters or leaves the belief network
- user-interface-is-verified-and-fault-tolerant — The complete user-facing stack is both structurally verified (pure delegation with hermetic integration tests ensuring no business logic leaks into the CLI) and operationally resilient (every information flow path is fault-tolerant with graceful degradation and governed output) — users never encounter unverified logic or ungoverned failure modes.
Dependents
These beliefs depend on this one:
- external-surface-is-verified-trust-bounded-and-bidirectionally-controlled — The system's complete external perimeter achieves defense-in-depth through three independently-established properties: structural verification (pure delegation with hermetic tests), trust boundaries (self-containment and defensive ingestion), and bidirectional flow control (token budgets constraining output, hardened LLM integration constraining input) — no external interaction bypasses all three layers.
