Page-split sub-sessions (current_step=2) had orientation marked as skipped
but uiStep remained at 0 (orientation step), causing StepOrientation to
render for a sub-session that has no orientation data. Now advances to
uiStep=1 (deskew) when orientation is skipped.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The reset useEffects in StepOrientation/Deskew/Dewarp/Crop were clearing
orientationResult when sessionId changed (e.g. during handleOrientationComplete),
causing the right side of ImageCompareView to show nothing. Using key={sessionId}
on the step components instead forces React to remount with fresh state when
switching sessions, without interfering with the upload/orientation flow.

The page-split detection was only implemented in the regular pipeline
page but not in the OCR Overlay page where the user actually tests
with Kombi mode. Now the overlay page has full sub-session support:
- openSession: handles sub_sessions, parent_session_id, skip logic
for page-split vs crop-based sub-sessions, preserves current mode
- handleOrientationComplete: async, fetches API to detect sub-sessions
- BoxSessionTabs: shown between stepper and step content
- handleNext: returns to parent after sub-session completion
- handleSessionChange/handleBoxSessionsCreated: session switching

handleOrientationComplete was checking subSessions from React state,
but due to batching the state was still empty when the user clicked
"Seiten verarbeiten". Now fetches session data directly from the API
to reliably detect sub-sessions and auto-open the first one.

After orientation detection, the frontend now automatically calls the
page-split endpoint. When a double-page book spread is detected, two
sub-sessions are created and each goes through the full pipeline
(deskew/dewarp/crop) independently — essential because each page of a
spread tilts differently due to the spine.
Frontend changes:
- StepOrientation: calls POST /page-split after orientation, shows
split info ("Doppelseite erkannt"), notifies parent of sub-sessions
- page.tsx: distinguishes page-split sub-sessions (current_step < 5)
from crop-based sub-sessions (current_step >= 5). Page-split subs
only skip orientation, not deskew/dewarp/crop.
- page.tsx: handleOrientationComplete opens first sub-session when
page-split was detected
Backend changes (orientation_crop_api.py):
- page-split endpoint falls back to original image when orientation
rotated a landscape spread to portrait
- start_step parameter: 1 if split from original, 2 if from oriented

- New ImageLayoutEditor: SVG overlay on original scan with draggable
column dividers, horizontal guidelines (margins/header/footer),
double-click to add columns, x-button to delete
- GridTable: MIN_COL_WIDTH 40→80px for better readability
- Arrow up/down keys navigate between rows in the grid editor
- Ctrl+Click for multi-cell selection, Ctrl+B to toggle bold on selection
- getAdjacentCell works for cells that don't exist yet (new rows/cols)
- deleteColumn now merges x-boundaries correctly
- Session restore fix: grid_editor_result/structure_result in session GET
- Footer row 3-state cycle, auto-create cells for empty footer rows
- Grid save/build/GT-mark now advance current_step=11

- New document category "Woerterbuch" (frontend type + backend validation)
- Column delete: hover column header → red "x" button (with confirmation)
- Column add: hover column header → "+" button inserts after that column
- Both operations support undo/redo, update cell IDs and summary
- Available in both GridEditor and StepGridReview (Kombi last step)

- New StepGridReview component: split-view (scan image left, grid right),
confidence stats, row-accept buttons, zoom controls
- Kombi Pipeline case 6 now uses StepGridReview instead of plain GridEditor
- Kombi step label changed to "Review & GT"
- Ground Truth queue page simplified to overview/navigation only
(links to Kombi pipeline for actual review work)
- Deep-link support: /ai/ocr-overlay?session=xxx&mode=kombi

- Ground-truth: zone.columns use 'label' not 'col_type' — calling
.replace() on undefined crashed the page after grid data loaded
- Model-management: same AIToolsSidebarResponsive wrapper bug as the
other pages — does not render children
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
AIToolsSidebarResponsive does not accept children — it renders only a
sidebar nav. Using it as a wrapper caused page content to never render.
Replaced with plain div, matching the pattern used by ocr-pipeline.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Both pages passed `moduleId` which is not a valid prop for PagePurpose.
The component expects explicit title/purpose/audience — calling
audience.join() on undefined caused the client-side crash.

Users can now draw rectangles on the document image in the Structure
Detection step to mark areas (e.g. header graphics, alphabet strips)
that should be excluded from OCR results during grid building.
- Backend: PUT/DELETE endpoints for exclude regions stored in structure_result
- Backend: _build_grid_core() filters all words inside user-defined exclude regions
- Frontend: Interactive rectangle drawing with visual overlay and delete buttons
- Preserve exclude regions when re-running structure detection

Graphic detection needs word positions to exclude text from the ink mask.
Previously Struktur ran before OCR, causing every word to be detected as
a graphic element. Now:
- Pipeline: Struktur at index 7 (after Wörter)
- Kombi: Struktur at index 5 (after PP-OCRv5+Tesseract, before Tabelle)

Add cv_graphic_detect.py for detecting non-text visual elements (arrows,

graphics on structure overlay image and display them in the frontend

column bold toggle, header row toggle, undo/redo, keyboard navigation
(Tab/Enter/Arrow), image overlay verification, and save/load.

Since ocr_region_paddle() now runs RapidOCR locally (same PP-OCRv5 models),
the "PaddleOCR (Hetzner)" labels were misleading. Renamed to "PP-OCRv5 (lokal)".
Removed the Kombi-Vergleich tab since both sides would produce identical results.

Cell-First OCR (v2): Each cell is cropped and OCR'd in isolation,
eliminating neighbour bleeding (e.g. "to", "ps" in marker columns).
Uses ThreadPoolExecutor for parallel Tesseract calls.
Document type detection: Classifies pages as vocab_table, full_text,
or generic_table using projection profiles (<2s, no OCR needed).
Frontend dynamically skips columns/rows steps for full-text pages.
