 ### Functional
 
 - [Cached source IR](../../../core/shader/recompiler/Recompiler.cpp) releases lazily allocated SSA construction tables after resource preparation and reclaims values unreachable from instructions, metadata and resource plans when retaining a pending source program. Immediate shader preparation skips reclamation because compilation consumes the program. Reclamation must account for every new IR pointer owner; a remaining external use throws. Live IDs are retained. Source and variant entries remain cached without an eviction bound. A pending source program is released after its first variant is obtained; memory beyond the measured title checkpoint and Linux performance remain unmeasured.
+- [Vertex user-data tail jumps](../../../core/shader/recompiler/ControlFlow/src/GraphBuilder.cpp) link a linear raw vertex prolog's terminal `s_setpc_b64` through an unchanged user-data pair to its continuation. The instruction semantics follow AMD RDNA2 ISA section 12.3; the prolog convention follows Mesa `aco_select_vs_prolog.cpp` at `0b2d6d1a61d9bbf89cf8beb88a696144f67c61f8`. Console hardware has not been measured. Computed pointers, branching prologs, fragment epilogs and continuations reading `s_getpc_b64` remain unsupported
 
 - The [resource tracker](../../../core/shader/recompiler/Optimization/src/ResourceTracker.cpp) plans a [descriptor source](../../../core/shader/recompiler/Optimization/src/SrtWalker/SrtDescriptorEvaluation.cpp) used only behind a conditional branch as inactive when the branch condition reads only clean (specialization) memory and so is evaluable at capture time; an inactive source is bound as zero words and not validated. Other conditions (EXEC, VCC, SCC set by vector or non-clean data, loop headers) leave every source active, as before, and a branch on a value that changes between dispatches is a specialization key like any other clean slot. PPSA15246 has a copy kernel that selects a buffer or an image path from an SRT word and reads the same address as a V# or a T#; before, the untaken path's descriptor was validated and threw. Whether the console would also accept an invalid descriptor in a path it does not take is assumed, not measured
 - [MaskedSelectEliminator](../../../core/shader/recompiler/Optimization/src/MaskedSelectEliminator.cpp) can discard inactive source lanes through `ReadFirstLane` only when its read mask implies the write mask and its result is unobserved outside the read mask. A loop-local read mask requires result uses in the same block without phi transport. The empty-EXEC lane-zero fallback follows AMD's [Vega ISA, section 12.8, V_READFIRSTLANE_B32, page 127](https://www.amd.com/content/dam/amd/en/documents/radeon-tech-docs/instruction-set-architectures/vega-shader-instruction-set-architecture.pdf) and the existing SPIR-V emitter. The optimization is covered by synthetic IR tests but has not been compared with console hardware; a proof that needs a read mask of a kind that is already being solved is refused.
