Address independent review: plan 09

Read .orchestration/plan-09-review.md, pinned plan 09, current AGENTS.md, RTK, and applicable receiving-code-review/documentation skills. Verify two findings against current source before editing; both are provisionally accepted.

Edit only two approved guide files:

• In export guide, scope “excludes cover letter sections” to rendered PDF/DOCX/Markdown output and state JSON retains embedded cover-letter custom sections. Keep distinction from independent cover-letter JSON.
• In version-history guide, do not claim template changes create independent checkpoints. Describe template changes as ordinary editing covered by throttled snapshots; retain accurate explicit import/AI/API/restore checkpoint statements.

Do not alter local Git workflow, add runtime code, promise whole-account restore/sync, or widen scope. Rerun focused source checks, API/import/schema/web tests if wording relies on them, Markdown lint, synthetic Git workflow as needed, git diff --check, and two-file scope gate. Add normal follow-up commit. Write .orchestration/plan-09-review-fix.md with exact commit/files, verified source facts, commands/results, skipped gates, and risks. Do not push/open PR/merge/mutate issues/spawn subagents. Final response at most ten lines.
