QUANTUM.

QUANTUM is the hard-sciences specialist. It produces symbolic and numerical work across physics and mathematics, with proof-carrying outputs where the chain of reasoning is itself a verifiable artefact. The brain's outputs are signed under the audit ledger so a peer reviewer can replay the computation step-by-step. QUANTUM coordinates with JAXON on numerical implementation, with TITAN on engineering application, and with EXFINITUM on cosmology and astrophysics.

• 01Symbolic and numerical computation
• 02Proof-carrying derivations and uncertainty propagation
• 03Domain handoff to applied engineering and astrophysics
• 04Signed replay records for peer-review reproduction

Authoritative external corpora and standards this brain treats as canonical. Every retrieval against these sources is signed into the audit ledger so a regulator can prove which evidence drove which output.

• 01arXiv math.* and physics.* papers
• 02INSPIRE-HEP
• 03Physical Review series
• 04AMS MathSciNet
• 05NIST CODATA fundamental constants
• 06IUPAC nomenclature
• 07Particle Data Group Review
• 08Mathematical Reviews and Zentralblatt MATH
• 09Springer Nature physics archives
• 10Stanford Encyclopedia of Philosophy (philosophy of science)

Mickai-native tooling primitives this brain implements internally. Codex for sovereign plain-text graph PKM, Lectern for spaced-repetition memory, Stele for citation-provenance, and domain-native primitives layered on top. No external services in the trust path; data stays on operator-personalised hardware.

• 01Codex (sovereign plain-text graph PKM)
• 02Stele (physics and maths citation graph)
• 03Slate (symbolic computation surface)
• 04Quill (mathematical typesetting and notebooks)
• 05Aperture (instrument and observation primitive)
