- new named constant LANDMARK_I32_WEIGHT_CEILING (0x7fffffff) in
landmark.ts: a seconds/quantumS quotient at or past 2^31 would wrap
NEGATIVE on the Int32Array store, silently bypassing the
LANDMARK_MAX_QUANTA throw in dijkstraPass (a negative contribution
never exceeds it) and — at a -1 wrap — becoming the 0xFFFF sentinel;
prepare() now fails loud at the table-build entry, naming the edge,
the ceiling and the fix (raise landmarkQuantumS)
- 'nothing is clamped, ever' now holds at the storage boundary;
validation is per-edge at build entry — the search hot path stays
allocation-free and validation-free
- L5b regression vector: 3e10 s edge (3e11 quanta) throws in both
landmarkTables and farthestPointAnchors; just-under-ceiling
(2147483646) still fails via the documented 65000 law; ordinary
weights untouched
