    "The frozen research instruction is parsed; scientific scope, feasibility, restricted or regulated activities, missing inputs and budgets are assessed. Unsafe or impossible studies are rejected with reasons.",
  framing:
    "A precise question, hypotheses or propositions, the intended contribution and a discipline-appropriate methodology are recorded, with evaluation criteria fixed before any test is run and honest null-result pathways identified.",
  literature:
    "Real scholarly registries (Crossref, OpenAlex, arXiv, PubMed, Semantic Scholar as applicable) are searched. Each reference is verified by identifier before it can be cited; a claim-to-source map is built. No reference is cited merely because a model believes it exists.",
  design:
    "Depending on the mode: genuine, legally usable data with documented provenance and licence; formal definitions and planned derivations; benchmark environments with baselines, seeds and leakage controls; or a search protocol with inclusion criteria. Synthetic simulations are labelled as synthetic.",
  execute:
    "Real code, experiments, simulations, formal checks or substantive qualitative work are executed in an isolated workspace. Environment, versions, seeds, commands and outputs are logged, including failures and negative findings.",
  robustness:
    "Sensitivity analyses, alternative specifications, stronger baselines, stress tests, proof checks or counterexample searches are run, and results that weaken the contribution are reported.",
  manuscript:
    "A LaTeX manuscript is generated from the recorded results with a real BibTeX database; every reported number must derive from stored artifacts.",
  review:
    "A separate review context that did not author the manuscript critiques novelty, validity, evidence, mathematics, statistics, references, ethics and writing. A response-to-review document records revisions. This is automated critique, not human peer review.",
  reproduction:
    "Scripts are re-executed and the PDF is rebuilt in a clean environment. Tables, figures, arithmetic, citation identifiers, fonts and build health are checked; representative pages are inspected.",
  quality:
    "Deterministic gates run on the control plane, independent of the authoring model. A hard failure blocks publication regardless of any review score.",
  publication:
    "A permanent paper number is allocated, artifacts are promoted with their digests, and the paper, feed and sitemap are updated transactionally. Automatic release requires every hard gate to pass; sensitive modes require human approval.",

        Production is a durable state machine of stages with evidence requirements, not a single enormous
        prompt and not a cast of fictional named agents. The platform policy controls permissions, sandboxes,
        budgets and publication; the uploaded research instruction controls only the academic task.

        Empirical, computational, theoretical, review, experimental and humanities modes each carry their own
        required artifacts and checks. Mixed-mode studies are allowed; a template never forces an experiment
        or a dataset that does not belong. Human participants, clinical interventions or biosafety-relevant
        work are out of scope unless documented approvals exist; otherwise work is restricted to lawful
        literature, public data, mathematics and simulations.
