{"path":"research/catching-a-proposal-made-unnecessary/cases/AX10.md","content":"*Spoken name: one zoom moves both folds, in five levels.* *About: What the map shows as a reader zooms out and in.* **One zoom moves sideways and chain folds together, in five levels: grounds (each route folded to the far claims it rests on), arguments (one card per argument and per cut whole, separate reasons stacked), reasons (today's default), parts (list items opened) and steps (the steps written under links shown); what is on screen at one level stays when zooming in, opened in place.** **Meets:** applies AX4 and AX8; extends AR3 (ruled: room the map gains goes to the next ring out); the persistence condition of semantic zoom (`graph-visualization.md` § 3). Reverses nothing settled. Home: `folding-joining-and-zoom.md` § 5. **Outside reader:** extends AR3 (\"one zoom moves sideways and chain folds together, in five levels\" against \"Room the map gains (a zoom out, a wide window) goes to the next ring out into the graph, not to more reasons side by side: about three cards stand across at every size\"); extends AX8 (\"One zoom moves sideways and chain folds together, in five levels\" against \"the map, the truth graph and every other surface zoom both ways: sideways, parts of one cut joined into their sentence or opened into their parts, and along a chain, links folded into a route or opened into their steps\"); depends on B2 (\"grounds (each route folded to the far claims it rests on)\" against \"The floor is separability — decompose until nothing separable is still bundled\"). His requirement, 2026-10-24: *\"Any fold vertically/deeper in the graph needs to assess and prioritize - live and as such it needs to be done by code and instant graph computation if at all possible - which claims should be shown in the view and which should be left out.\"*; and on showing a fold: three dots along the line, a three-way line with dots on each branch for a folded subgraph, zoom directed at the hovered area with a modifier key (`folding-joining-and-zoom.md` § 8).\n"}
