pandoraReuse begins with identity.
Content-addressed blocks carry sparse vectors or exact key/value state. Import checks namespace, conditioning, generation, shape, finite values, checksum and contiguous parent history before admitting a block. Matching bytes alone do not establish a compatible workload.
Freeze before you carry.
The cache checks the resident-to-carried transition with symbolic codegen (PandoraSymbolicLinalgLib), Salsa and Z3 before export. Only frozen exports travel; live step state stays local. Invalidated records cannot be revived, and a new generation requires a new record. Hosts must authorize tenant transfers: a checksum verifies content, not the sender.
Describe intent in PD-native.
The version-2 .pd grammar gives symbolic workloads a typed path through pd-native check and plan. Validated formulas lower into compiler source artifacts and launch plans. The broader language direction brings portable caches and compute objectives into the same declaration; a source-artifact plan does not execute a GPU kernel.
A portable contract, with explicit boundaries.
The cache crate provides bounded blocks and a validated JSON transfer envelope. Tensor conversion and network transport still need runtime integration. Compiler memoization is local and separate from portable cognitive state; portability does not make compiled GPU artifacts interchangeable across hardware.
