…3850) Document the signature pipeline (sequential, pipelined, rayon-parallel) under crates/signature/, capture per-block rolling and strong-checksum costs, project 1/4/16/64 thread scaling on 100 MB / 1 GB / 10 GB bases, and propose tuned chunk sizing, per-thread scratch reuse, prologue overlap with the pipelined reader, SIMD-batched rolling checksum, and GPU offload as deferred future work.

…3943) Replace the prior scaling audit with a concise plan focused on empirically locating the parallel signature path's thread-count ceiling. Document the parallel.rs entry points, frame the compute-bound versus memory-bandwidth-bound question, specify a criterion bench across 1/2/4/8/16 threads with 4K/8K/16K block sizes, predict saturation around 8 threads on commodity DDR4, and recommend capping rayon workers and renaming the threshold env override to PARALLEL_SIGNATURE_THRESHOLD.
