revision-is-lifecycle-safe-and-semantics-preserving
OUT derived (depth 4)
Both revision entry points — reactive contradiction resolution (backtracking to least-entrenched premise, skipping retracted nodes) and proactive dialectical challenge (outlist injection preserving evaluation semantics) — respect node lifecycle and preserve semantic consistency despite operating through different mechanisms.
Summary
The system has two ways to revise its knowledge — fixing contradictions after they appear, and proactively challenging assumptions before they cause problems. This claim says both approaches are well-behaved: they clean up or restructure the network without corrupting node states or breaking how the system evaluates truth. Since this claim is currently out, at least one of those safety guarantees is in question, meaning revisions through one or both pathways might not be as reliable as expected.
Justifications
SL — depth-4 — two independent revision mechanisms (reactive nogoods, proactive challenges) share lifecycle safety and semantic preservation, suggesting these are system-level invariants not per-feature accidents
Antecedents (all must be IN):
- contradiction-resolution-is-lifecycle-safe — When contradictions are detected, the entire resolution pipeline respects node lifecycle: backtracking identifies the least-entrenched culprit premise deterministically, retraction cascades through BFS propagation that skips retracted nodes and stops on unchanged truth values, ensuring resolution terminates without disturbing lifecycle-inert nodes.
- dialectical-transformation-preserves-semantics — Challenging a premise irreversibly transforms its identity from unjustified to justified node, but the resulting dialectical structure inherits complete outlist semantics — conjunction over multiple outlists, absence-as-OUT permissiveness, and persistence survival — ensuring the transformation preserves well-defined evaluable behavior.
Dependents
These beliefs depend on this one:
- revision-is-universally-safe — The complete revision system has no blind spots: every belief — including all semantic edge cases (vacuous premises, asymmetric absence, empty antecedents) — can be revised through either reactive or proactive paths while preserving semantic identity and respecting node lifecycle states.
- revision-spans-lifecycle-and-all-sources — The revision system is safe across two orthogonal dimensions: node lifecycle (backtracking skips retracted nodes, propagation respects lifecycle states, challenge preserves semantics through irreversible transformation) and modification source (dialectical, LLM, multi-agent) — ensuring no revision path is unsafe regardless of the node's lifecycle state or the belief's origin.
