+# Handover — WP12B — v13.6 Two-mode UI app verification closeout
+
+Repository: `solidprivacy-nl/scrub`  
+Status: completed and app-verified after Actions/sync verification
+
+## Summary
+
+WP12B administratively closes the v13.6 two-mode UI line.
+
+Closed sequence:
+
+- WP12 introduced the two-mode UI skeleton.
+- WP12-FIX cleaned up content separation.
+- WP12-FIX2 fixed the generated indentation/runtime error around `Scrub Key laden`.
+- WP12B records successful GitHub Actions, Hugging Face sync and app verification.
+
+The previous blocking runtime error was:
+
+```text
+IndentationError: unexpected indent
+File "/home/user/app/presidio_streamlit.py", line 380
+    st.markdown("**Scrub Key laden**")
+```
+
+This is now verified fixed in the app.

+
+## Validation status
+
+GitHub Actions: green based on coordinator evidence.  
+Hugging Face sync: green based on coordinator evidence.  
+App verification: confirmed by coordinator/user.
+
+## App verification status
+
+Confirmed.
+
+Coordinator/user verified:
+
+- The app starts without Script execution error.
+- No `IndentationError` appears.
+- `Originele waarden terugzetten` mode is visible and selectable.
+- In `Originele waarden terugzetten`, the full anonymization workflow is no longer shown above the reinsert flow.
+- `Scrub Key laden` is visible.
+- Scrub Key upload/paste is visible.
+- `Valideer en laad Scrub Key` is visible.
+- Local pasted-text reinsert section is visible.
+- Warning about restored sensitive/confidential values is visible.
+- Local-only / no-AI / no-cloud text is visible.
+- Text field for reinsert is visible.
+- Button `Zet originele waarden lokaal terug` is visible.
+- No TXT upload reinsert UI appears.
+- No DOCX upload reinsert UI appears.
+- No PDF reinsert appears.
+- No AI/cloud behavior appears.
+
+Also recorded:
+
+- `Anonimiseren` mode remains available.
+- Existing anonymization workflow remains available in `Anonimiseren`.
+- Existing Scrub Key export/import remains available.
+- Existing pasted-text reinsert remains available.
+
+## Boundaries preserved
+
+- No code files changed.
+- `fix_streamlit_nested_expanders.py` was not changed in WP12B.
+- `presidio_streamlit.py` was not changed.
+- `scrub_key_document_reinsert.py` was not changed.
+- `scrub_key_reinsert.py` was not changed.
+- `scrub_key.py` was not changed.
+- `scrub_key_import.py` was not changed.
+- No test files were changed.
+- No TXT upload reinsert UI added.
+- No DOCX upload reinsert UI added.
+- No PDF reinsert added.
+- No AI calls added.
+- No cloud processing added.
+- No automatic document rehydration added.
+- No existing TXT, CSV, DOCX or PDF scrubbed export/download behavior intentionally changed.
+- No Scrub Key export/import behavior intentionally changed.
+- No secrets, tokens or real personal data stored.
+
+## Remaining risks
+
+- None for the WP12B closeout itself.
+- Future UI work should remain sequential because `fix_streamlit_nested_expanders.py` and Streamlit workflow state are still sensitive patch areas.
+- WP13 should be started only as a separate workpackage.
+
+## Next recommended step
+
+```text
+WP13 — v13.7 TXT reinsert upload/download UI
+```
+
+WP13 should remain limited to TXT reinsert upload/download UI and must not introduce DOCX upload reinsert UI, PDF reinsert, AI/cloud behavior or export semantic changes.
