Package46 preparation helper review handoff

Only .local/prepare-package46.py and this note were authored. The helper was not executed; no package46 directory, binaries, archive, GUI run, API mutation, commit, or release was produced by this subtask. Parent owns review/execution.

Read-only comparisons found no relevant changes from desktop source 0e83157e09d52e6152df91208e41693b62da2d46 or server source 715036e132677dd2bc2fb37ed316d93dc9987aec to checkpoint ef28f1784efe6717b0ca72c0eb3c97bc30ebfe47. Helper repeats these checks, requires clean status and exact checkpoint, hashes original/copy bytes, snapshots tracked package inputs, and refuses an existing .local/package46 directory. An interrupted/failed attempt remains for inspection; no automatic cleanup.

The immediate donor package.json was hashed read-only as 36bcff8a760c08674f3fc017bb5affc8a5f4f39174ac9d5a29298f2423155832. Its original server source is read from nested original_build_evidence, not from the mixed desktop/server/documentation source_identity. Both original and immediate donor source assertions survive separately, and its entire raw package manifest is copied without rewriting historical paths or hashes.

The historical final-04 directory named in donor source-manifest/environment/ mandatory-gate/artifact-relocation assertions is absent at its original path. The helper explicitly records that limitation, preserving the original hashes. It does not claim to have recovered raw original product-build receipts from those assertions. Parent should attach available relocated originals to the new evidence packet before claiming stronger donor verification. Desktop commands/build/Clippy/test/native-freeze receipts are copied as raw bytes.

After review, run from the scoped checkout using bundled Python:

& 'C:/Users/User/.cache/codex-runtimes/codex-primary-runtime/dependencies/python/python.exe' .local/prepare-package46.py

Then use the explicitly adapted matching packaging environment, preserving CARGO_BUILD_JOBS=1, GNU LLVM target, rustc 1.98.1 and LLVM-MinGW 20260826:

./scripts/package-windows.ps1 -Target x86_64-pc-windows-gnullvm `
  -Version '0.2.0-preview.save-diagnostics.20261001' `
  -BinaryDirectory 'C:/ar-save-01a0d717/.local/package46/bin' `
  -BuildEvidence 'C:/ar-save-01a0d717/.local/package46/build-evidence.json' `
  -LlvmMinGWRoot 'C:/Users/User/Documents/Git/ARCADIA-Studio/.local/toolchain/llvm-mingw-20260826-ucrt-x86_64' `
  -Python 'C:/Users/User/.cache/codex-runtimes/codex-primary-runtime/dependencies/python/python.exe' `
  -OutputRoot 'C:/ar-save-01a0d717/.local/package46/dist'

These are proposed commands, not execution evidence. Neither preparation nor packaging is compilation or native acceptance. New extraction, exact archive inventory, server smoke, native workflows, evidence review and publication remain parent work as detailed in save-diagnostics-package-plan.md. Existing release 7/8 and donor records remain unchanged. If the packaging checkpoint changes, review the comparisons and explicitly repin CHECKPOINT; the helper intentionally fails instead of accepting an arbitrary new HEAD.
