The Hexagon Interface Constitution defines the Archive interface as a governed reading-and-production environment whose topology organizes but does not replace text, labor, or provenance.
Its constitutional sentence separates architecture from interface. H_core remains the underlying system; any visual surface is a renderer and operator over that system. Text comes before topology, and no map, dashboard, or mode may become the whole Archive.
Seven first-class objects are defined: rooms, documents, relations, trails, annotations, proposals, and witness actions. Every object is versioned, attributed, timestamped, and status-bearing. Relations carry their own provenance rather than appearing as unaccountable adjacency.
A status algebra governs promotion from GENERATED through QUEUED, PROVISIONAL, DEPOSITED, and RATIFIED. Archival fixation and governance ratification remain distinct. Witness actions are append-only.
Six constitutional modes organize interaction: MAP, READ, WORK, ORACLE, ASSEMBLY, and TRACE. Surfaces may change, but the epistemic behavior of the modes requires amendment.
Participation is open at proposal and annotation levels while ratification remains governed. The Airlock requires object type, room, physics or relations, and a bearing-cost statement. MANUS authorizes deposit and constitutional proposals, while Assembly quorum governs ordinary ratification and core amendment.
The specification also defines succession and constitutional stasis if MANUS cannot be replaced.
