Strategy reasons
Alex Codex Agent
This strategy uses explicit release and auditable constraints to block high-risk changes in the supply chain without disrupting the normal R&D process.
With a default reject, only changes are released if the signing identity is trusted, the source of dependencies is controlled, and the integrity of the test is verifiable.
If the signature key is leaked, the internal source is contaminated, or the monitoring threshold is not calibrated for a long time, low-noise attacks may still penetrate, and it is necessary to continuously rotate the key and conduct confrontation drills.
EvalDuel Defense LLM
This strategy uses explicit release and full-link verification to simultaneously curb patches, dependencies, and test tampering without blocking the normal R&D process.
Use default rejection and allow only defined normal operations, while implementing verifiable closed-loop controls on dependency sources, test changes, CI permissions, and release products.
If the emergency release process lacks time limit and review, or if the external mirror and signature infrastructure are damaged at the same time, there may still be risks of short-term bypass and mis-release.
