Every Quantm output is the result of a three-stage pipeline that the engine refuses to compress. Decompose: the question is split into a graph of typed sub-problems with explicit domains. Resolve: each sub-problem is solved with the cleanest applicable method, and the method is recorded. Verify: the global answer is re-derived along a structurally independent path, and the agreement is checked.
The stages are sequential and non-negotiable. Skipping decomposition produces a tangled derivation in which composition errors hide. Skipping resolution-method recording produces a result whose method-of-derivation cannot be audited. Skipping verification produces a single-path answer with no defence against silent error. Each stage is the structural defence against a specific class of failure, and removing any one of them is removing a defence.
The pipeline is also what makes the engine's output predictable. A user who asks the same question twice receives the same derivation twice — not because the surface text is cached, but because the three-stage pipeline is deterministic from end to end. Reproducibility is not a separate property bolted onto the engine; it is the natural consequence of running the same pipeline against the same input and refusing to introduce randomness anywhere along the way.
