The cache key held a literal NUL byte instead of its escape, so git classified the whole module as binary: it landed as `Bin 0 -> 2677 bytes` with zero diffable lines, invisible to review, to grep, and to any textual merge. The escape is behaviour-identical. With the file readable, two things in it needed fixing. Eviction cleared the entire map. Clearing changes the identity of every lane's automation at once, and a lane compares its drag draft against that identity — so one unrelated element arriving at the limit would release an in-progress drag and snap the point back. It now drops the oldest entry, and a hit is re-inserted so it counts as recently used. Nothing tested this module, which is what let the binary blob through. Now covered: identity stability, re-parsing when the chain changes but the automation text does not, a hot entry surviving 40 evictions, and an unreadable attribute reading as nothing. The geometry module's exports are ignored for dead-code while its consumer sits one PR upstack, following the convention already used for the fast-capture stack.
