- 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

Changed `typeof grid.zones[][]` to `GridZone[][]` which was causing
a silent build error, preventing the vsplit zone grouping logic from
being compiled into the production bundle.

Pages with two side-by-side vocabulary columns separated by a vertical
black line are now split into independent sub-zones before row/column
detection. Each sub-zone gets its own rows, preventing misalignment from
different heading rhythms.
- _detect_vertical_dividers(): finds pipe word_boxes at consistent x
positions spanning >50% of zone height
- _split_zone_at_vertical_dividers(): creates left/right PageZone objects
with layout_hint and vsplit_group metadata
- Column union skips vsplit zones (independent column sets)
- Frontend renders vsplit zones side by side via flex layout
- PageZone gets layout_hint + vsplit_group fields

Post-processing steps like 5h (slash-IPA conversion) modify cell.text
but not individual word_boxes. The colored per-word display showed
stale word_box text instead of the corrected cell text. Now falls
back to the plain input when texts don't match.

Footer rows (e.g. page numbers) now show "F" in amber below the row
number, mirroring the blue "H" label for headers.

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

- Ground Truth button on last step of Pipeline/Kombi modes in ocr-overlay
- Prominent category picker in active session info bar (pulses when unset)
- GT badge shown when session has ground truth reference
- Backend: auto-detect pipeline from ocr_engine, store in GT snapshot
- Pipeline info shown in GT session list and regression reports
- Also pass pipeline param from ocr-pipeline StepGroundTruth
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Extract _build_grid_core() from build_grid() endpoint for reuse.
New ocr_pipeline_regression.py with endpoints to mark sessions as
ground truth, list them, and run regression comparisons after code
changes. Frontend button in StepGroundTruth.tsx to mark/update GT.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The frontend was checking for an existing structure_result and reusing
it, which meant the backend fix (passing word_boxes to graphic detection)
never had a chance to run on existing sessions.

When union columns from multiple content zones are applied, column
boundaries can span wider than any single zone's bbox. Using
zone.bbox_px.w as the scale reference caused the total scaled width
to exceed the container, pushing the table off-screen.
Now uses the actual total column width sum as the scale reference,
guaranteeing columns always fit within the container.

Backend: merge gaps within 5% of image width — the spine area may have
thin ink strips splitting one physical gap into multiple detected gaps.
Only use gaps >= 2% width as split points.
Frontend: StepCrop now handles multi_page crop responses without
crashing on missing original_size/cropped_size fields.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Backend: add layout_metrics (avg_row_height_px, font_size_suggestion_px)
to build-grid response for faithful grid reconstruction.
Frontend: rewrite GridTable from HTML <table> to CSS Grid layout.
Column widths are now proportional to the OCR-measured x_min/x_max
positions. Row heights use the average content row height from the
scan. Column and row resize via drag handles (Excel-like).
Font: add Noto Sans (supports IPA characters) via next/font/google.

When a cell has colored words (red !, blue phonetics), render each
word as a separate span with its own color instead of coloring the
entire input text with the first non-black color found.
Switches to editable input on cell selection (click).

Add cv_graphic_detect.py for detecting non-text visual elements (arrows,
circles, lines, exclamation marks, icons, illustrations). Draw detected
graphics on structure overlay image and display them in the frontend
StepStructureDetection component with shape counts and individual listings.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
New pipeline step between Crop and Columns that visualizes detected
document structure: boxes (line-based + shading), page zones, and
color regions. Shows original image on the left, annotated overlay
on the right.
Backend: POST /detect-structure endpoint + /image/structure-overlay
Frontend: StepStructureDetection component with zone/box/color details

- Add color/color_name/recovered fields to OcrWordBox type
- GridTable: show colored text + left-edge color indicator strip
- GridEditor: show color stats and recovered count in summary bar
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Backend: new grid_editor_api.py with build-grid endpoint that detects
bordered boxes, splits page into zones, clusters columns/rows per zone
from Kombi word positions. New DB column grid_editor_result JSONB.
Frontend: GridEditor component with editable HTML tables per zone,
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.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add /rapid-kombi backend endpoint using local RapidOCR + Tesseract merge,
KombiCompareStep component for parallel execution and side-by-side overlay,
and wordResultOverride prop on OverlayReconstruction for direct data injection.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Backend: Add spatial overlap check (>=50% horizontal IoU) to Kombi merge
so words at the same position are deduplicated even when OCR text differs.
Frontend: Add yPct/hPct to WordPosition so each word renders at its actual
vertical position instead of all words collapsing to the cell center Y.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Runs both OCR engines on the preprocessed image and merges results:
word boxes matched by IoU, coordinates averaged by confidence weight.
Unmatched Tesseract words (bullets, symbols) are added for better coverage.

The slide positioning hook was re-matching cell.text tokens against
word_boxes via fuzzy text similarity, which broke positioning for
special characters (!, bullet points, IPA). Now uses word_box
coordinates directly — exact OCR positions without re-interpretation.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
New 2-step mode (Upload → PaddleOCR+Overlay) alongside the existing
7-step pipeline. Backend endpoint runs PaddleOCR on the original image
and clusters words into rows/cells directly. Frontend adds a mode
toggle and PaddleDirectStep component.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Replace sequential 1:1 token-to-box mapping with fuzzy text matching.
Each token from cell.text finds its best matching word_box by text
similarity (normalized prefix match + substring bonus). Handles:
- Reordered boxes (different sort between text and boxes)
- IPA corrections changing token boundaries
- Token/box count mismatches
Unmatched tokens get interpolated positions from matched neighbors.

When engine=paddle is selected, the backend overrides grid_method to
words_first and returns plain JSON (no SSE streaming). The frontend
was not aware of this override — it sent stream=true and tried to parse
SSE events from a JSON response, resulting in "Keine Daten".

PaddleOCR als neue engine=paddle Option in der OCR-Pipeline.
Microservice auf Hetzner (paddleocr-service/), async HTTP-Client
(paddleocr_remote.py), Frontend-Dropdown, automatisch words_first.

TEXT kommt aus cell.text (bereinigt, IPA-korrigiert).
POSITIONEN kommen aus word_boxes (exakte OCR-Koordinaten).
Tokens werden 1:1 in Leserichtung zugeordnet.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Backend: _ocr_cell_crop speichert jetzt word_boxes mit exakten
Tesseract/RapidOCR Wort-Koordinaten (left, top, width, height)
im Cell-Ergebnis. Absolute Bildkoordinaten, bereits zurueckgemappt.
Frontend: Slide-Hook nutzt word_boxes direkt wenn vorhanden —
jedes Wort wird exakt an seiner OCR-Position platziert. Kein
Pixel-Scanning noetig. Fallback auf alten Slide wenn keine Boxes.

Gruppen-Sliding schob nicht weit genug nach rechts. Zurueck zum
Original-Einzelwort-Slide, aber mit den Fixes:
- fontRatio=1.0 (konsistente Schriftgroesse wie Fallback)
- Token-Breiten aus medianCh * 0.7 / refFontSize (statt totalInk)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Vorher: split(/\s+/) zerlegte alles in Einzelwoerter, verlor die
Spaltenstruktur (3+ Spaces zwischen Gruppen). Woerter stauten sich links.
Jetzt: split(/\s{3,}/) erhält Gruppen wie im Cluster-Modus. Jede Gruppe
wird als Einheit von links nach rechts geschoben bis Tinte gefunden.
Breite = max(gemessene Textbreite, tatsaechliche Tintenbreite).
fontRatio=1.0, kein Wort geht verloren.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
fontRatio war 0.65 (35% kleiner als Fallback-Rendering). Jetzt 1.0
wie beim Fallback. Token-Breiten berechnet aus measureText skaliert
auf die tatsaechlich gerenderte Schriftgroesse (medianCh * 0.7).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Schriftgroesse wird jetzt GLOBAL aus der medianen Zellhoehe berechnet
(65% der Zellhoehe als Ziel-Font). Alle Tokens bekommen dieselbe
konsistente Groesse. Die Slide-Logik bestimmt nur noch die x-Position.
Vorher: Scale pro Zelle aus Ink-Span/Textbreite -> inkonsistente Groessen.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
totalInk zaehlte nur dunkle Pixel-Spalten (Striche), ignorierte
Luecken zwischen Buchstaben. Scale war dadurch viel zu klein,
Schrift unlesbar. Jetzt wird der Ink-Span (erstes bis letztes
dunkles Pixel) als Referenz fuer die Textbreite verwendet.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Neuer Hook useSlideWordPositions: Schiebt alle erkannten Woerter von links
nach rechts ueber die Pixel-Projektion bis jedes Wort auf seiner Tinte
einrastet. Kein Wort geht verloren, keine Cluster-Matching-Regeln noetig.
Toggle-Button (Slide/Cluster) in der Overlay-Toolbar zum Umschalten.
Bestehender Cluster-Algorithmus bleibt als Alternative erhalten.

Zwei wesentliche Verbesserungen:
1. Multi-group: Gruppen werden per Best-Fit-Breite den Clustern
zugeordnet statt naiv links-nach-rechts. Damit wird z.B.
"Kokosnuss" dem DE-Spalten-Cluster zugeordnet statt dem
breiteren Box-Cluster.
2. Single-group Fallback: verwendet den BREITESTEN Cluster statt
first-to-last Span. Verhindert dass Streupixel von benachbarten
Seitenbereichen den Text nach links ziehen.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Box-Rahmen werden vom OCR als einzelne Symbole wie "|" oder ">"
erkannt und als eigene Text-Gruppen behandelt. Das verfaelscht die
Cluster-Zuordnung weil diese Artefakte entweder keinen eigenen
Cluster erzeugen oder den falschen Cluster zugewiesen bekommen.
Fix: Gruppen mit max 2 Zeichen ohne Buchstaben/Ziffern werden mit
der benachbarten Gruppe zusammengefuehrt bevor die Cluster-Zuordnung
laeuft.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Wenn mehr Pixel-Cluster als Text-Gruppen existieren (z.B. wegen
Box-Rahmenlinien), werden jetzt die N breitesten Cluster ausgewaehlt
statt naiv clusters[i]→groups[i] zuzuordnen. Text-Cluster sind
breiter als Rahmenlinien-Cluster.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Vorher: wenn Text mehr Wort-Gruppen hatte als Pixel-Cluster gefunden
wurden (z.B. bei Box-Rahmen die Cluster zusammenmergen), wurde die
Zelle komplett uebersprungen → Fallback bei x=0%.
Jetzt: Fallback auf Single-Span Positionierung (first→last Cluster)
statt Skip. Damit wird der Text immer korrekt horizontal platziert.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
1. Schriftgroesse basiert jetzt auf Median-Zeilenhoehe statt
individueller Zellhoehe — keine Groessensprunge in Box-Bereichen
2. Sehr schmale Pixel-Cluster (< 0.5% Zellbreite) werden gefiltert,
damit Box-Rahmen nicht als Textposition erkannt werden
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
_heal_row_gaps verschiebt Zell-Positionen nach Entfernung von Artefakt-Zeilen,
was im Overlay zu sichtbarem Versatz fuehrt (z.B. 23px bei "badge").
Neuer skip_heal_gaps Parameter in build_cell_grid_v2 und words-Endpoint
behaelt die exakten Zeilen-Positionen bei.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Seiten mit Info-Boxen (andere Zeilenhoehe) fuehren dazu, dass _regularize_row_grid
die Zeilenpositionen verzerrt. Neuer skip_regularize Parameter nutzt stattdessen
die gap-basierten Zeilen, die der tatsaechlichen Seitengeometrie folgen.

Statt Side-by-Side wird der erkannte Text jetzt direkt ueber das

Das cropped image ist bereits orientierungskorrigiert. Die zusaetzliche
180°-Rotation ueber imageRotation drehte das Bild falsch herum.
imageRotation wird weiter fuer Pixel-Matching genutzt, aber nicht mehr
