sample-mode-is-deterministic
IN premise
`_build_beliefs_section` with `sample=True` and a fixed `seed` produces identical output across calls, enabling reproducible derive prompts
Summary
When the belief-building code runs in sampling mode with the same seed value, it always produces the same output. This means the prompts sent to the LLM during belief derivation are fully reproducible, making it possible to debug, test, and verify the derive process reliably.
Dependents
These beliefs depend on this one:
- derive-prompt-is-deterministic-and-reproducible — The derive pipeline's prompt construction is fully reproducible: deterministic sampling with fixed seeds selects consistent belief subsets, and accurate proportional budget allocation ensures each agent receives the same token share across runs.
