Independent review: plan 09 local Git backup documentation

Review only; do not edit, commit, push, open PR, mutate issues, or spawn subagents. Read current worktree AGENTS.md, RTK, issue/domain guidance, code-review/documentation skills, .orchestration/plan-09-implementation.md, and approved plan 09. Trust local planning checkout only when HEAD equals a2557b2ad40e06e1e63eb655f286e6a78fe6bf0d; otherwise use pinned git show for plans/09-external-version-backup.md.

Fetch current origin/main and live issue/PR state. Confirm reviewed commit and inspect full origin/main...HEAD diff. Verify claims against current export/import/version source and tests, then review:

Correctly distinguish single-resume JSON, embedded cover-letter sections, independent cover-letter JSON, and account archive. Account archive must not be presented as single-resume import or whole-account restore.
User code uses plain local Git commands only: targeted git add --, inspect diff, commit, show. No rtk, remote URL, credentials, git push, global Git config mutation, or automatic sync.
Restore is import-as-new and non-destructive. Filenames stable. Images described as URL references with availability risk. Private-data and repository-visibility warning is prominent and actionable.
Existing rolling history comparison is accurate and non-duplicative. Scope contains exactly two approved docs.
Synthetic validation/report evidence is reproducible; note database/E2E skips accurately and inspect whether retained temp path creates any repository or privacy risk.

Rerun focused API/import/schema/web tests, Markdown lint, disposable local-Git sequence using synthetic data, and diff/scope checks where practical. Record skipped DB/E2E gates. Findings first, severity-ordered with file/line and evidence. If none, state No findings plus residual risks.

Write .orchestration/plan-09-review.md with reviewed SHA/base, findings, commands/results, skipped gates, risks, and verdict ready for publication or changes required. Final response at most ten lines.
