Design 47 at hq main b229f5c4, lines 1353-1366 (each entry one module version on a node, its edges provisioning and acting; each revision naming its inputs, kept as objects in the old section with its cap, served by the seat's verbs), 1385-1388 (under 256 KiB for 120 modules on four nodes; a 512 MiB cap), 1416-1418 and 522-525 (a node's entries from the catalog graph of the branch its placement names, by default the registration's first), 909-914 (the placement's build is the version), 1835-1836 (an edge from the acting part's version to each version its rule names), and the Reverted table (assignment graph revisions as objects, form 1). internal/assigngraph computes a revision from the halves held per branch, the placements and the capability readings; keeps it numbered after the newest when it differs, each entry once by its digest; and answers revision, entry and difference from the kept objects only. The manifest serves the three verbs and declares the objects assignment-revisions. A placed module whose entry cannot be computed is named in Uncomputed, never left out in silence. Not built here (the design does not say, or held): contribution edges; provisioning to a provider no binding or pin names; tiers; a candidate's revision (W5.9); removal of a revision no record pins (pins are W5.9's). The process does not compute and keep yet: that needs the registrations' first view and a catalog half per branch (handover). Milestone 47/G, issue 1966. Tests: TestTheAssignmentGraphIsComputedFromItsInputsAndKept, TestARevisionOf120ModulesOnFourNodesFitsOneValue, TestTheSeatsVerbs/1953/D4-D6 (failed before), TestManifest's objects row (failed with the old manifest).
