Architecture and internals¶
How Bernstein works under the hood, for readers extending it or deciding whether its design fits their constraints.
-
System
Top-level architecture, task lifecycle, model routing, state persistence.
-
Concepts
The building blocks - fingerprint memoization, lineage trail, spec-as-test.
-
Orchestration internals
Task DAG, run actor, worker coordination, failure taxonomy.
-
Decisions (ADRs)
Why the orchestrator is deterministic, file-based, and LLM-free at the core.
