feat(phase-15-ghi): three case studies — completes all six system archetypes#16
Merged
Conversation
Adds the Funitel de Péclet, Ngong Ping 360 and Whistler chairlift case studies. With jig-back, MGD and 3S already validated, these add the remaining three RopewaySystemType families, so every system archetype in the catalogue now has a real-installation validation run. The validation set grows from 6 to 9 installations across four continents. Phase 15g — Funitel de Péclet (Val Thorens), funitel - The world's first funitel (1991). Optimizer reproduces the ≈ 650 m elevation gain exactly from terminal coordinates + the N45/E006 DEM tile (reused from the Aiguille du Midi study). Phase 15h — Ngong Ping 360 (Hong Kong), BGD bi-cable gondola - Optimizer reproduces the two-phase profile — a low bay crossing under WATER clearance, then a sustained Lantau climb. The straight corridor (5 248 m) trails the 5 700 m as-built route by the angle-station dogleg, an honest documented gap and a Phase 12c plan-view target. Phase 15i — Whistler Mountain chairlift, chairlift - Validates the CHAIRLIFT catalogue defaults produce the archetype signature: short spans (mean 187 m, max 226 m ≤ 300 m limit), dense towers, low tension (198 kN — an order below the jig-back studies). Reuses the N50/W123 DEM tile. Chairlifts publish little headline data, so the doc is explicit that this validates the system model rather than claiming a tight numeric as-built match. All three runs are feasible. New example scripts + case-study docs + committed artifacts (PNG, DXF, LandXML, GeoJSON, CSV, BOM, cost, PDF). README + CHANGELOG updated — nine installations, all six archetypes. No source changes; the optimizer/test suite is untouched. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
