WalkthroughThe bundler now creates tarballs with Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~15 minutes Change: Refactor Suggested reviewers: Merge Risk: 🔵 Low · up to The integration workflow awaits extraction correctly. Permission-only changes can still alter bundle hashes, with less normalization than before; merging requires awareness of this bounded reproducibility regression. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The archive remains gzip-compressed tar, and the changed extraction helpers remain test utilities. File permissions now depend on the staged files rather than the previous portable handling. No new production entrypoint or privilege escalation was demonstrated, but deployment-side permission enforcement remains unverified. Retained concerns

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick winNormalize archive modes before hashing.
modern-taruses the sourcestat.modewhenFileSource.modeis unset. The previousnode-tarcall usedportable: true, which removed group and other write bits before writing headers. This PR therefore makes modes such as0644and0664produce different archive bytes and hashes. Normalize regular files to0644, and preserve executable entries as0755when required.Suggested fix

The rest of this PR LGTM, but I'd feel better about it if someone with domain expertise reviewed the finer behavioural details of this diff here. Maybe @JakeChampion?
