user-interface-is-verified-and-fault-tolerant
OUT derived (depth 6)
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.
Summary
Everything a user touches — from typing a command to seeing results — has been verified to contain no hidden logic and will handle failures gracefully without exposing raw errors or uncontrolled output. This is currently marked as unsupported because one or both of its foundations (the verified delegation chain or the fault-tolerant information flow guarantees) are themselves not held to be true.
Justifications
SL — Verified atomic delegation chain (depth-4) combined with fault-tolerant governed information flow (depth-5) establishes the user interface as both correct and resilient
Antecedents (all must be IN):
- full-user-stack-is-verified-atomic-delegation — The full user-facing stack forms a verified chain of atomic delegation: the CLI is structurally pure delegation verified through hermetic integration tests, and every mutation flowing through the API layer is atomic, audited, and produces observable before/after diffs — ensuring end-to-end traceability from user command to persisted state change.
- all-information-flow-is-fault-tolerant-and-governed — Every information flow path through the system is simultaneously fault-tolerant (graceful degradation on FTS5 index failures, LLM timeouts, and missing source files) and governed (pure deterministic functions with fixed priority ordering, access-tag authorization gating, and token-budget constraints) — no information retrieval can fail catastrophically, and no information output can bypass authorization or exceed bounds.
Dependents
These beliefs depend on this one:
- external-surface-is-verified-and-trust-bounded — 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.
- verified-interface-controls-bidirectional-flow — 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.
