Breakage analysis per dependency

Kamino Lend's assessment for RD-F-052 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Scope failure halts all klend price operations. Pyth stale on single-feed reserve halts that reserve. MostRecentOf reserves fall back if secondary within staleness. kToken DEX pool oracle manipulation possible for thin pools.

Detail #

Critical path: klend → Scope → {Pyth, Switchboard, Chainlink, DEX pools}. Scope program failure is single point of failure for all price-gated operations. SPL Token/System failures are chain-level events. See External Dependency Graph in .md report for full per-dependency breakdown.
