external-surface-is-verified-and-trust-bounded
OUT derived (depth 7)
The complete external-facing surface achieves both structural verification (pure delegation with hermetic tests and fault tolerance across all information paths) and comprehensive trust enforcement (architectural self-containment with information flow control at every boundary) — no external interaction bypasses either the verification chain or trust controls.
Summary
Every point where the system touches the outside world — user interfaces, external APIs, data ingestion — is covered by two independent safety nets: one that verifies the code structure is correct and tested, and one that controls what information is allowed to cross each boundary. This is currently not held because one or both of its supporting claims have been retracted, meaning there may be gaps in either the verification chain or the trust controls at the external surface.
Justifications
SL — Verified fault-tolerant interface + comprehensive trust boundaries means the external surface has no unverified or unbounded interaction path
Antecedents (all must be IN):
- 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.
- trust-and-information-boundaries-are-comprehensively-enforced — The system enforces comprehensive boundaries spanning both architecture and information flow: architectural trust boundaries through self-containment and defensive ingestion pipelines ensure no unvalidated data enters the network, while information boundaries through access-tag authorization, token-budget constraints, and bidirectional external surface control ensure no unauthorized or unbounded data leaves it
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.
