# kaal:position:2026-08-08-228

**Affirmed position.** A Smart Contract Vulnerability Detection Method Based on Heterogeneous Contract Semantic Graphs and Pre-Training Techniques states that smart contracts cannot be modified or revoked after blockchain deployment. This independently supports the immutability mechanism in Kaal's DAO-code vulnerability claim. The abstract does not establish that every deployed contract lacks an upgrade path or that a particular bug has appeared.

**Status.** affirmed  **Published.** 2026-08-08

**Holds when.**

- The response is limited to the retrieved source proposition and mapped Kaal claim unless fuller source review supports a broader conclusion.
- External evidence level: abstract indexed.
- Mapping review tier: substantively reviewed abstract-level agreement.
- Primary mapping confidence: 0.62.
- The primary mapping cleared the automated ambiguity test; substantive scope remains review-bound.
- Evidence is limited to an exact proposition in a Crossref-indexed abstract; full text was not reviewed.
- No relationship is treated as external endorsement, citation, causation, or validation of a broader Kaal claim.
- The source states that smart contracts cannot be modified or revoked after blockchain deployment. This independently supports the immutability mechanism in Kaal's narrower DAO-code vulnerability claim, while it does not establish that every deployed contract lacks an upgrade path or that a particular bug has appeared.
