WORKFLOW BRIEF → GALAXY
A reviewed brief is the entry point, including a hand-authored brief. The harness checks declared blockers, review, and current environment readiness before any design. Galaxy design Molds consume the brief directly; a retained source summary remains optional evidence rather than an intermediate authority.
The input brief remains unchanged. open-requirements.ledger.yml records durable workflow discoveries, decisions, obligations, and proposed brief changes; ordinary phase progress remains harness state. Only a separate expert editing step can change scope or requirements. A required brief change stops implementation and returns to that editing step.
Source-to-brief journeys remain independently usable so they can finish with an honest blocked draft. The paper and interview direct journeys remain separate, freeform-summary-driven routes; planning is explicit composition of a source-to-brief producer with this brief-driven implementation spine. This initial implementation route does not yet dispatch to the specialized Nextflow reference-data and test-translation chain.
