PSM 7 (single line) missed the second line in cells with two lines.
PSM 6 handles multi-line content. Also fix sort order to Y-then-X
for correct reading order.

Backend: build_word_grid() intersects column regions with content rows,
OCRs each cell with language-specific Tesseract, and returns vocabulary
entries with percent-based bounding boxes. New endpoints: POST /words,
GET /image/words-overlay, ground-truth save/retrieve for words.
Frontend: StepWordRecognition with overview + step-through labeling modes,
goToStep callback for row correction feedback loop.
MkDocs: OCR Pipeline documentation added.

- Add REGULATION_SOURCES map with 88 original document URLs for all
regulations (EUR-Lex, gesetze-im-internet.de, RIS, Fedlex, etc.)
- Render "Originalquelle →" link in regulation detail panel
- Add amber warning indicator for suspiciously low chunk counts (<10)
- Add EU_IFRS_DE, EU_IFRS_EN, EFRAG_ENDORSEMENT to RAG tracking

Build a word-coverage mask so only pixels near Tesseract word bounding
boxes contribute to the horizontal projection. Image regions (high ink
but no words) are treated as white, preventing illustrations from
merging multiple vocabulary rows into one.

Add Step 4 (row detection) between column detection and word recognition.
Uses horizontal projection profiles + whitespace gaps (same method as columns).
Includes header/footer classification via gap-size heuristics.

New regulations across bp_compliance_ce (11), bp_compliance_gesetze (31),
and bp_compliance_datenschutz (1). Collection totals updated:
gesetze 58304, ce 18183, datenschutz 2448, total 103912.

Column detection now uses vertical projection profiles to find whitespace
gaps between columns, then validates gaps against word bounding boxes to
prevent splitting through words. Old clustering algorithm extracted as
fallback (_detect_columns_by_clustering) for pages with < 2 detected gaps.

Local variables named 'isInRag' shadowed the outer function, causing
"isInRag is not a function" error. Renamed to regInRag/codeInRag.

- Chunks column now uses getKnownChunks() instead of API-based getRegulationChunks()
- Status column uses isInRag() check (green/red) instead of ratio-based calculation
- Key Intersections chips show green/red with checkmark/cross based on RAG status

- Reduce left-side threshold from 35% to 20% of content width
- Strong language signal (eng/deu > 0.3) now prevents page_ref assignment
- Increase column_ignore word threshold from 3 to 8 for edge columns
- Apply language guard to Level 1 and Level 2 classification
Fixes: column with deu=0.921 was misclassified as page_ref because
reference score check ran before language analysis.

Address 5 weaknesses found via ground-truth comparison on session df3548d1:
- Add column_ignore for edge columns with < 3 words (margin detection)
- Absorb tiny clusters (< 5% width) into neighbors post-merge
- Restrict page_ref to left 35% of content area across all 3 levels
- Loosen marker thresholds (width < 6%, words <= 15) and add strong
marker score for very narrow non-edge columns (< 4%)
- Add EN/DE position tiebreaker when language signals are both weak

Sub-alignments within a column (indented words, etc.) were 60-90px apart
and not getting merged at 3%. On a typical 5-col page (~1500px), 6% = ~90px
merges sub-alignments while keeping real column boundaries (~300px) separate.

Clusters now track Y-positions of their words and filter by vertical
coverage (>=30% primary, >=15%+5words secondary) to reject noise from
indentations or page numbers. Merge distance widened to 3% content width.

- ManualColumnEditor now uses grid-cols-2 layout (image left, controls right)
matching the normal view size so the image doesn't zoom in
- StepColumnDetection only runs auto-detection when no cached result exists;
revisiting step 3 loads cached columns without re-running detection

Replace projection-profile layout analysis with Tesseract word bounding
box clustering to detect 5-column vocabulary layouts (page_ref, EN, DE,
markers, examples). Falls back to projection profiles when < 3 clusters.

The old displacement-map approach shifted entire rows by a parabolic
profile, creating a circle/barrel distortion. The actual problem is
a linear vertical shear: after deskew aligns horizontal lines, the
vertical column edges are still tilted by ~0.5°.
New approach:
- Detect shear angle from strongest vertical edge slope (not curvature)
- Apply cv2.warpAffine shear to straighten vertical features
- Manual slider: -2.0° to +2.0° in 0.05° steps
- Slider initializes to auto-detected shear angle
- Ground truth question: "Spalten vertikal ausgerichtet?"
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The old -3.0 to +3.0 scale multiplied the full displacement map (up to ~79px)
directly, causing extreme distortion at values >1. New slider:
- 0% = no correction
- 100% = auto-detected correction (default)
- 200% = double correction
- Step size: 5%

Tesseract OCR + 70 Debian packages + pip dependencies are now in a
separate base image (klausur-base:latest) that is built once and reused.
A --no-cache build now only rebuilds the code layer (~seconds) instead
of re-downloading 33 MB of system packages (~9 minutes).
Rebuild base when requirements.txt or system deps change:
docker build -f klausur-service/Dockerfile.base -t klausur-base:latest klausur-service/

- Fix dewarp method selection: prefer methods with >5px curvature over
higher confidence (vertical_edge 79px was being ignored for text_baseline 2px)
- Add grid overlay on left image in Dewarp step for side-by-side comparison
- Add GET /sessions/{id} endpoint to reload session data
- StepDeskew accepts sessionId prop to restore state when navigating back
- SessionInfo type extended with optional deskew_result and dewarp_result

The formula int(17 - grade*3) was off by one for grades 1.0 and 1.3

match the intended mapping (1.0=15, 1.3=14).

Der Geo-Service (DSGVO-konforme Geografie-Lernplattform) war ein
nie genutzter Prototyp und wird nicht mehr benoetigt. Entfernt aus:

- session_manager: add session to _local_cache in create_session()
so get_session() and get_active_sessions() work without Redis/Postgres
- message_bus: use asyncio.create_task() in request() for publish
so handler runs concurrently and timeout actually fires
All 76 tests pass now.
