- routeAstar's ONLY change: the h_f/h_b bodies become max(ALT triangle
bounds, haversine) — per-search Float64Array(L) constant tables in quanta
(0xFFFF written as NaN = search-scoped landmark drop), lazy per-node
max over the four triangle families with RAW u16 sentinel compares
BEFORE any float conversion, haversine max-fallback on sentinel-flooded
nodes (Pattern 3 containment)
- the (h_f - h_b)/2 combination, reductions, balanced alternation, meet
probes, BH stop rule, and real-seconds reconstruction are byte-identical
(research Pattern 1 — the survey's (pf-pr)/2 is what p_f already is)
- no Map/Object allocations (A8 green), no new imports, one search path
(L >= 1 is the decodeGraph guarantee, D-01)
- A1's 625-pair Dijkstra-equivalence sweep re-pinned under ALT: the
standing optimality proof; A9 island + A10 skip laws sealed; A11
structural pin green
- module header + routeAstar doc gain the ALT paragraph (c-metric
exactness, sentinel laws, Ikeda history intact)
