Chopper evidence

Selected Chopper browser records, one reviewed E5 public derivative and a labeled synthetic download fixture. Download the exact stored bytes and verify them with the SHA-256 below.

The two historical records cover specific builds and workloads. They include unsuccessful attempts and correctness timings; they do not establish current platform coverage or comparative performance. The synthetic fixture tests download acceptance only.

  Only reviewed operational path roots and four tool-path dictionary labels use CHECKOUT, CARGO_HOME and MSVC_TOOLCHAIN aliases; numerical values, 24 measured jobs, 16 untimed controls, mixed timings and the startup outlier remain. Historical hash maps do not restore missing replay inputs. This environment-specific panel supports no general worker speedup claim.

  Transformation: Exact root substitution in reviewed string values and key labels only; windows, slash and JSON-escaped spellings; preserve suffix bytes; reject key collisions. UTF-8 JSON, indent=2, ensure_ascii=False, LF, final newline; retain insertion order.
