+## ADL-068 — Standalone topology document and nullable NUMA affinity
+
+**Date:** 2026-09-14
+**Context:** A server topology cannot distinguish the real NUMA node 0 from an
+unknown affinity while the Go model uses numeric zero as its absence sentinel.
+Bee support bundles also contain useful relationships (DIMM-to-socket,
+disk-to-controller, and GPU/NVLink links) which are not part of the Reanimator
+hardware ingest schema. Adding those relationships to `reanimator.json` would
+couple a standard inventory document to one viewer.
+
+**Decision:**
+- Represent `numa_node` as `*int` throughout LOGPile's PCIe, network, canonical
+  device, and Reanimator projection models. `nil` means absent/N/A; `&0` means
+  NUMA node 0.
+- Keep `reanimator.json` schema-preserving. Store semantic topology as a
+  separate, versioned `topology.json` document containing nodes and edges, but
+  no presentation coordinates.
+- Render `/topology/current` as a LOGPile-owned, static SVG page opened in a
+  separate browser tab. Do not modify the `internal/chart` submodule.
+- The Easy Bee parser may retain the small static evidence files required to
+  enrich topology. Rendering must never execute commands, poll metrics, or
+  depend on live state.
+
+**Consequences:**
+- JSON can round-trip both an absent NUMA affinity and the real value 0.
+- Ordinary inputs get the topology supported by their normalized inventory;
+  rich Bee bundles additionally get memory, storage-controller, and NVLink
+  relationships.
+- Raw-export ZIP bundles include `topology.json` separately from
+  `reanimator.json`.
+- Fan RPM animation, PSU live load, and other Bee live-only presentation are
+  intentionally out of scope.
