+
+Build on server/src/atlas/road_graph.rs:
+1. Hub selection: ''real cities, scaled cap'' — wiki cities anchor the MST; cap scales with body size; standalone HQs/minor settlements are non-hub.
+2. Co-location collapse: group same-named settlements (defensive; the D-242 corp-HQ fix removes most at source).
+3. Hybrid minor-settlement attach: snap to nearest existing road edge if close, else spur to nearest hub (add edge-split-at-attach).
+4. RailHeadFacing junction pass (T-1038 step 6, deferred): junction settlements (RoadGraph::high_connectivity_junctions already computed) get FoundingOrientation::RailHeadFacing. REQUIRES a D-213 amendment (adopted enum has no RailHeadFacing) + Layer-4 skeleton_gen handling.
+
+Needs population ranking — blocked on the corp-HQ-model + population-bake tickets.
+
+---
+Refinement (2026-07-16, /whats-next Si review + gap resolution with Jeroen):
+
+SCOPE ITEM 0 (added — placement-map correction, precedes hub work): corp_hq_placement.toml over-generalized D-242''s Standalone boundary (bulk_class != NonPhysical -> Standalone gave 95 Standalone / 60 CityTenant, incl. distilleries/wineries/leatherworks as standalone belt settlements). Jeroen''s ruling, faithful to D-242''s own examples: Standalone ONLY where the HQ is itself an industrial complex / company town — extraction/mining/quarrying, heavy vehicle + shipyard manufacturing, heavy energy (refinery/extraction complexes), gate/orbital infrastructure. Everything else CityTenant, explicitly including craft/consumer manufacturing (distilleries, breweries, wineries, ceramics, textiles, furniture), agriculture (estate offices sit in market towns), and high-tech fabs. Re-author per-value (judge each of the 31 value descriptions against this boundary), regen, and amend D-242 to state the boundary explicitly so it cannot be re-coarsened; record Jeroen''s "edge of settlement / clusters" color as CityTenant rendering detail for later phases, not a third placement class.
+
+1. Hub selection (gap: no cap formula, no HQ-row identity): RESOLUTION — thread an is_standalone_hq flag through read_body_settlements/CityRecord (join corporations.headquarters_body + proper_name where hq_placement=''Standalone''; the city_context_reader.rs:1165-1170 test comment predicted exactly this threading). Hubs = top-cap by population among NON-HQ cities; cap scales with body size via a documented inline constant (existing workshop-tunable pattern in road_graph.rs), sanity-checked on 2-3 bodies of different sizes.
+
+2. Co-location collapse (gap: zero live cases, no rule): RESOLUTION — ship trivial defensive: exact (body_id, name) match collapses to one node keeping lowest id, loud log warning when it ever fires.
+
+3. Hybrid minor-settlement attach (gap: no snap threshold, no edge-split machinery): RESOLUTION — engineer''s judgment: design the edge-split representation + pick the snap threshold as a documented inline constant; extend the RoadEdge/RoadNode invariants and the ten existing unit tests accordingly.
+
+4. RailHeadFacing (well-specified per Si): add the FoundingOrientation variant (consumers use if-let, no exhaustive-match break), assign via existing RoadGraph::high_connectivity_junctions (degree >= 3, matches D-213''s paula-round3 source), amend D-213, and make the skeleton_gen rotation call inline (Si''s suggested default: face the junction''s dominant incident-edge bearing).
+
+Deferred (no preference given): standalone-HQ Zipf population shares stay as-is (e.g. Gate Corporation 909M on GJ251c); the item-0 re-tune shrinks standalone rows to genuine company-towns where a real share is defensible. Revisit if Atlas numbers read wrong.
