The architecture of the digest has transitioned from a conceptual [recognition surface](https://aswritten.ai/narrative#Position_AbsenceIsNoRecognizedAssociation) to a concrete [product surface](https://aswritten.ai/narrative#Narrative_DigestBrowserProductSurface), formalizing the human's role as a consumer of the same collapse-expand navigation used by the system. Central to this is the [visibility invariant](https://aswritten.ai/narrative#Narrative_VisibilityInvariantAreaIndex), which ensures the [index never gates the store](https://aswritten.ai/narrative#Position_IndexNeverGatesStore) by naming every hub in every response. To balance this with steering, [richness and visibility are separated](https://aswritten.ai/narrative#Narrative_RichnessVsVisibilitySeparation), allowing for tier weighting without demotion. The system now organizes [perspective responses by volatility](https://aswritten.ai/narrative#Narrative_PerspectiveResponseOrderedByVolatility), maintaining a stable skeleton while appending focus. Furthermore, [reconciliation is now defined as a set transaction](https://aswritten.ai/narrative#Narrative_ReconciliationAsSetTransaction), surfacing the referent set to the user, while a pending [content-commentary split](https://aswritten.ai/narrative#Narrative_ContentCommentarySplit) seeks to distinguish primary integration from authored commentary, ensuring [multiplicity in variation](https://aswritten.ai/narrative#Position_MultiplicityInVariation) remains the primary anti-reductionist mechanism.

Witness phrases
verbatim The product surface is the digest browser — the human as consumer of the same collapse/expand navigation that extraction and citation already use
verbatim Richness is a budget decision; visibility is an invariant — the principled separation that makes tier weighting compatible with compression-only
verbatim Perspective response ordered by volatility: stable skeleton leads, per-call focus appended last
verbatim Reconciliation is a transaction about a set of transactions or nodes — the design of correction and commentary about the past
verbatim Content/commentary split: per-message integration is the content layer; reconciliation is the authored commentary layer
verbatim Expansion is intended as a steering mechanism for relevant material, not as a discovery tool for whether content exists.
