fix(memory): resolver.resolve_edge_typed hardcodes 0.8 confidence — ignores LLM-provided value

[bug-ops]

Description

resolver.resolve_edge_typed in crates/zeph-memory/src/graph/resolver/mod.rs:628 passes hardcoded 0.8 as confidence instead of edge.confidence from LLM extraction. This silently overrides the LLM-provided confidence score for all edges in the non-APEX path.

Location

crates/zeph-memory/src/graph/resolver/mod.rs:628

Expected Behavior

edge.confidence from LLM extraction should be forwarded to the store.

Actual Behavior

All non-APEX edges receive confidence=0.8 regardless of what the LLM returned.

Environment

• Identified during PR fix(memory): propagate configured Benna-Fusi rates through extract_and_store #4722 test authoring
• Affects all edges written through the non-APEX resolver path

Impact

LLM confidence signals are discarded in the primary resolver path, reducing the quality of graph edge weighting and spreading activation results.
