Close remaining BusyBox notice review

[jacklv-coder]

Summary

Close the remaining BusyBox candidate-material license and attribution review as one coherent change.

• reconstruct the exact BusyBox source state by applying all 33 pinned Alpine aports patches and the pinned configuration
• derive the 487-unit dry-run build graph and its 562-file recursive local-include closure
• pin and review 41 additional source files that retain independent third-party terms, provenance, copyright, or redistribution notices
• increase BusyBox evidence from 19 to 60 files, initial candidates from 37 to 78, and reviewed external payloads from 97 to 138
• mark BusyBox candidate-material engineering coverage complete, leaving four other source origins with package-specific work
• keep complete NOTICE, legal review, corresponding-source, and redistribution gates closed

The audit excludes TLS-only sources because the pinned Alpine wget HTTPS patch leaves CONFIG_TLS disabled. Of the 41 selected files, only libbb/hash_md5_sha.c and shell/ash.c are touched by the fixed patch set; the five relevant patch payloads are separately pinned and do not remove or rewrite the relied-on notices.

Validation

• pre-push codex review --uncommitted: no findings
• ./Scripts/check-docs.sh
• compliance generator reproducibility check against the pinned RootFS archive
• SHA256SUMS verification
• 138-file reviewed notice bundle verification
• all Ruby compliance test suites
• RootFS candidate smoke manifest tests
• runtime smoke script tests
• ./Scripts/test.sh: 139 tests, 0 failures, 1 expected environment-only skip
• pinned RootFS archive integration test: 1/1 passed
• git diff --check
