@@ -1750,6 +1750,18 @@ state, not a persistent cache identity or a WEAR row. The observation narrows
the next terrain task to profiling the cache's generated entries and their
consumer; it still does not establish a Land1 blend equation.
The probe now also reads the bounded eight-byte entry table and only hashes
the fixed 212-byte profile banks it observes; raw process bytes never enter
the repository. The same AutoDemo cache had 3,426 materialized record pointers
among 3,462 entries and referenced banks `0..4`. Two consecutive captures
kept that count, bank set, and all five FNV-1a-64 bank hashes stable:
`9426539192111566946`, `2915543853261903601`, `13156371703608727216`,
`11280405573172155968`, and `18234288329145104612`. Their result views changed
from `0x008A565C` to `0x008A55A8`. Thus the generated cache/profile state is
stable over these render samples while the shared result view is not. This
still identifies neither the record-field semantics nor the final terrain
blend/pass operation.
