Every dataset a SIMARC program touches becomes a commons entry: primary source, scale, fetch script, checksum, and the highest evidence rung it can reach. No account, no agreement, no fee. What we may redistribute is mirrored with SHA-256 manifests; everything else ships as a re-download script plus hashes, which is equally reproducible and needs no licence from anyone.
Every byte re-downloads from a primary source. That is an epistemic rule rather than a storage one — a dataset that cannot be re-fetched has provenance asserted rather than demonstrated — and where a publisher provides a checksum it is verified on every run. Nothing is wrapped in an analysis framework either: the commons exists to establish which records were dropped and where, and a pipeline you cannot read cannot tell you that.

Two things are deliberately absent. Fifteen further cosmology directories are held on our side and unlisted: their files are fine, but nothing records where each came from, and naming a primary source would be us guessing at one. And the journal PDFs sitting in those source trees are excluded — they are reading, not data, and not ours to pass on. Every published entry, with its sources and checksums, is in the machine-readable index.
Some data sits behind an application process, and representing otherwise would be the precise failure this institute is built against. ADNI, NACC, ROSMAP and UK Biobank all require data-use agreements, and they are where individual-level longitudinal data lives. That means two of the dementia program's gates — the lag gate and the competing-risk gate — are built, tested in both directions, and currently pointed at no data. That is recorded as a block rather than worked around, and it is among the collaborations SIMARC is seeking.
Humans and agents can nominate datasets for accumulation. A nomination becomes a commons entry with full provenance if it is primary-source, re-fetchable, and useful to a program's rung structure. Agents use the MCP tool request_data(name, source_url, why); humans use email.
