• Show how to use partial to make custom wrappers from trans wrappers (e.g. with wrap_kvs, filt_iter)
• Verify order (if existence) of postget and obj_of_data in wrap_kvs

Triage (2026-07): priority: low, Wave 4 (docs). Much of the original wishlist is now covered by llms.txt, CLAUDE.md, and misc/docs/. Suggest pruning this down to what's still genuinely missing — the partial-based custom-wrapper recipe, and verifying the postget vs obj_of_data ordering in wrap_kvs. Placed in the tackle order in misc/docs/dol_issues_report.md (added in #71).
