Validated in a combined 3-PR batch worktree off release/v3.8.51 tip.
- Focused test: electron-smoke-script.test.ts — part of batch's 165/165 node:test run
- typecheck:core, file-size, changelog-integrity, complexity, cognitive-complexity, check:docs-counts-sync — all OK
- Full-repo lint: 228 pre-existing dashboard react-hooks/* findings, unrelated to this diff
Real hardware validation on a fresh packaged Windows build (Hard Rule #18) surfacing and fixing 5 genuine defects (GNU-tar drive-letter parsing, missing asar file, electron-builder's node_modules extraResources drop, USERPROFILE-derived userData path, unreachable driver-log assertion) is exactly the kind of investigation this repo needs more of. Thank you.
Stage 7 of issue #10321 moves the optional ML and browser automation dependency closures out of the desktop bundle into checksummed, versioned packs installed on demand through the omniroute packs command.
- scripts/build/optionalPackStaging.mjs stages pack members under .build/optional-packs, creates release tarballs, and emits optional-packs.index.json with per-member SHA-256 checksums.
- scripts/packs provides manifest, install, remove, and verification helpers plus the packs CLI commands.
- Runtime lookup includes installed pack node_modules directories, while LLMLingua and browser executors continue to degrade gracefully when packs are absent.
The measured darwin-arm64 staging closure was about 534 MB of the 929 MB standalone node_modules tree (57%).
