Agentic Atlas · Schema
Agent projection payload (agent/.json)
One successful result of the agent-projection/v8 envelope: exactly one compact coherence marker, the omitted fact classes declared in scope (with total, truncated, and next_cursor for collections), and the class data. The payload class is read off the data keys rather than echoed beside them, a collection is complete exactly when it is not truncated, and the count it returned is the length of the array it carries. The fact-class recovery mapping is declared once for the whole surface in tools.json rather than expanded per payload, a batch's subjects are read off its own data, and derived-content metadata lives in the sealed Release record rather than on the wire. No payload carries the corpus maturity rung. Cards carry expanded provenance only in one request-gated nested block; it is never default wrapper overhead or a second envelope. A Card claim carries the field the publisher authored it under alongside its text and sources. A complete-Node payload carries identity, hierarchy (ancestors and sibling place), Hook, and ordered Sections only; its relationship occurrences are the links fact class, declared omitted and recovered through atlas_links. Tree entries and tour steps are ordered by their place in their arrays. A definition read carries exactly the display term and its definition. An Orient whose caller omitted query altogether may carry a usage note on how the tool is meant to be called; its candidates are exactly the query='' listing, and an explicit query carries no note.
