Engineering notes on the execution plane for agentic systems — deterministic runs, saga compensation, policy gates, and the evidence trail behind every claim.
Exploring how Escepine uses deterministic Cedar policies to enforce hard authorization boundaries between LLM-generated tool calls and execution, preventing unauthorized actions in high-stakes enterprise workflows.
Deterministic execution ensures a workflow with identical inputs always yields the exact same states and outputs. For critical systems like finance or healthcare, this predictability provides vital reliability. It eliminates race conditions and enables safe failure recovery through history replay, preventing data corruption and downtime.
Demos test the happy path; production tests every path. What changes between the two, and the checklist that tells you whether your agent survives it.
96% step accuracy sounds safe — chain 20 steps and run reliability lands at 44%. The math of compounding failure, and the infrastructure that fixes it.
