CIPHER is the sealed surface where Aequara's pre-publication AI research lives. Model amendment drafts, embargoed Brier predictions, sub-index reconciliations awaiting publication, the methodology-hash custody log, and the model-card archive. Trustee-tier gated, encrypted at rest, audited by named stewards.
Index reconciliations awaiting next-cycle publication. Sub-index drafts. Methodology amendment proposals. The research that will be public 30 days from now is here today, for the Trustees who help shape it.
The amendment ledger itself — every operational change to the methodology, time-stamped, signed, and sealed. Methodology-hash changes are visible to Tier III Custodians earlier than to Tier II Trustees, by 14 days.
The current methodology hash is public. The history of all prior hashes, the reason each was rotated, and the steward who signed off — that's CIPHER. The audit trail that turns "trust us" into "verify us."
Every quarterly cycle, the Trustees see the next reconciliation, the proposed amendments, and the steward commentary before public publication. Not because the public can't handle it — because the Trustees provide the final cycle of pressure-testing. Their feedback letters during the embargo window are how Aequara catches errors before they go public. CIPHER is the room where that pressure-testing happens.
"For pedants. For poets. For people who pronounce it correctly."
