+## WP13 — v13.7 TXT reinsert upload/download UI
+
+Status: implemented; awaiting GitHub Actions, Hugging Face sync and app verification.
+
+Purpose:
+
+- Add controlled TXT upload/download support inside `Originele waarden terugzetten`.
+- Keep the existing pasted-text reinsert flow available as fallback.
+- Reuse the existing deterministic local TXT helper.
+- Keep DOCX upload reinsert UI, PDF reinsert, AI and cloud behavior out of scope.
+
+Files added or changed:
+
+- Changed `fix_streamlit_nested_expanders.py`.
+- Changed `tests/test_two_mode_ui_patch.py`.
+- Changed `WORKPACKAGES.md`.
+- Changed `CHANGELOG.md`.
+- Added `tests/test_txt_reinsert_ui_patch.py`.
+- Added `handover/workpackages/20260608_0000_v13_7_txt_reinsert_upload_download_ui.md`.
+
+Main change:
+
+- Added section `TXT-bestand terugzetten` inside the `Originele waarden terugzetten` mode.
+- Added TXT upload label `Upload een TXT-bestand met placeholders`.
+- Added action button `Zet TXT-bestand lokaal terug`.
+- Added output label `Herstelde TXT-tekst`.
+- Added download label `Download hersteld TXT-bestand (.txt)`.
+- The UI calls:
+  - `reinsert_txt_bytes(content, scrub_key, encoding="utf-8")`.
+- TXT reinsert requires a loaded Scrub Key before running.
+- The restored TXT result shows text output and an audit summary.
+- The existing pasted-text reinsert flow remains available.
+- The existing anonymization workflow remains in `Anonimiseren`.
+
+Safety/warnings:
+
+- The TXT reinsert UI warns that restored output may contain personal/confidential data again.
+- The UI states that reinsert is local-only and uses no AI/cloud processing.
+- The Scrub Key warning remains present and keeps the pseudonymization/reversibility context.
+
+Tests added/updated:
+
+- Added `tests/test_txt_reinsert_ui_patch.py`.
+- Updated `tests/test_two_mode_ui_patch.py`.
+
+The tests check:
+
+- `reinsert_txt_bytes` is imported and used;
+- TXT UI labels are present;
+- TXT upload accepts `.txt` only;
+- TXT reinsert requires a loaded Scrub Key;
+- TXT reinsert is injected only in the `Originele waarden terugzetten` mode;
+- pasted-text reinsert labels remain present;
+- `Scrub Key laden` remains present;
+- `Anonimiseren` remains present;
+- existing anonymization/export markers remain present;
+- existing Scrub Key export remains present;
+- no DOCX upload reinsert UI is added;
+- no PDF reinsert is added;
+- no AI/cloud behavior is added;
+- `apply_replacements_to_text` is not altered;
+- existing scrubbed download markers are not rewired.
+
+Validation:
+
+- Local clone/test run could not be performed in the container because outbound GitHub DNS was unavailable:
+  - `Could not resolve host: github.com`.
+- GitHub Actions: awaiting verification for WP13 commits.
+- Hugging Face sync: awaiting verification for WP13 commits.
+- App verification: required because UI behavior changed.
+
+Intentionally not changed:
+
+- `presidio_streamlit.py` was not directly edited.
+- No DOCX upload reinsert UI added.
+- No PDF reinsert added.
+- No AI calls added.
+- No cloud processing added.
+- No automatic document rehydration beyond TXT local reinsert added.
+- No existing TXT, CSV, DOCX or PDF scrubbed export/download behavior intentionally changed.
+- No Scrub Key JSON export behavior intentionally changed.
+- No Scrub Key import/reload behavior intentionally changed except reusing the loaded key for TXT reinsert.
+- No Scrub Key storage, secrets, tokens or real personal data added.
+
+Outcome:
+
+- WP13 is implemented and awaits GitHub Actions, Hugging Face sync and app verification.
+- Next recommended workpackage is `WP13-CLOSEOUT — v13.7 TXT reinsert upload/download UI app verification closeout`.
