format-resilient-boundaries-enforce-validated-trust
OUT derived (depth 4)
All system boundaries simultaneously tolerate format variation at every level — from LLM response parsing through schema migration to derive output versioning — while enforcing strict validated trust through typed exceptions, referential integrity checks, and hallucination filtering.
Summary
The system's external boundaries — where it talks to LLMs, reads files, or migrates data — are designed to handle messy or unexpected formats without breaking, while still rejecting genuinely invalid or hallucinated content. This claim is currently unsupported, meaning one or both of its foundations (broad format resilience or strict-yet-adaptive validation) have been undermined.
Justifications
SL — Format resilience (including list-negative prose-tolerant parsing) composes with strict validation and evolution tolerance — flexibility and correctness coexist at every boundary
Antecedents (all must be IN):
- format-resilience-spans-all-external-interfaces — The system tolerates format variation at every external interface — derive output parsers support version fallback, import parsers silently skip unknown fields, storage handles schema evolution — and extends this resilience to LLM response parsing, where the list-negative parser uses regex extraction to recover structured data from prose-laden responses.
- system-boundaries-are-validating-and-evolution-tolerant — All system boundaries simultaneously enforce strict input validation (typed exceptions, referential integrity checks, hallucination filtering) and tolerate evolution gracefully (dual format parsers, forward-compatible metadata, schema-tolerant loading) — boundaries are both strict about current invariants and adaptive to future changes.
Dependents
These beliefs depend on this one:
- trust-enforcement-is-structural-and-operationally-resilient — System trust boundaries are enforced through two complementary mechanisms: structural containment (zero external dependencies, defensive ingestion pipelines, safe three-layer architecture) provides static trust guarantees, while format resilience at all external interfaces (parser fallbacks, schema evolution tolerance, hallucination filtering) provides dynamic trust that adapts to changing external formats without relaxing validation.
