Word-lookup is now ~0.03s (vs seconds with per-cell Tesseract), so
always re-run detection when entering Step 5 instead of showing
potentially stale cached word_result from the session DB.

Cells now appear one-by-one in the UI as they are OCR'd, with a live
progress bar, instead of waiting for the full result.

Extract build_cell_grid() as layout-agnostic foundation from
build_word_grid(). Step 5 now produces a generic cell grid (columns x
rows) and auto-detects whether vocab layout is present. Frontend
dynamically switches between vocab table (EN/DE/Example) and generic
cell table based on layout type.

- Integrate Britfone dictionary (MIT, 15k British English IPA entries)
- Add pronunciation parameter: 'british' (default) or 'american'
- British uses Britfone (Received Pronunciation), falls back to CMU
- American uses eng_to_ipa/CMU, falls back to Britfone
- Frontend: dropdown to switch pronunciation, default = British
- API: ?pronunciation=british|american query parameter

Default collection changed from bp_compliance_gesetze (DE/AT/CH laws where
PDFs need manual download) to bp_compliance_ce (EU regulations where PDFs
are auto-downloaded). Added HEAD request check so missing PDFs show a clear
"PDF nicht vorhanden" message instead of a 404 in the iframe.

- Root container uses calc(100vh - 220px) for fixed viewport height
- All flex children use min-h-0 to enable proper overflow scrolling
- Removed duplicate bottom nav buttons (Zurueck/Weiter) that appeared
in the middle of the chunk text — navigation is only in the header now
- Chunk text panel scrolls internally with fixed header
- Added prominent article/section badges in header and panel header
- Added chunk length quality indicator (warns on very short/long chunks)
- Structural metadata keys (article, section, pages) sorted first
- Sidebar shows regulation name instead of code for better readability
- PDF viewer uses pages metadata from payload when available

- Preserve \n between visual lines within cells (instead of joining with space)
- Rejoin hyphenated words split across line breaks (e.g. Fuß-\nboden → Fußboden)
- Split oversized rows (>1.5× median height) into sub-entries when EN/DE
line counts match — deterministic fix for missed Step 4 row boundaries
- Frontend: render \n as <br/>, use textarea for multiline editing

The Qdrant collections use regulation_id (e.g. eu_2016_679) as the filter key,
not regulation_code (e.g. GDPR). Updated rag-constants.ts with correct qdrant_id
mappings from actual Qdrant data, fixed API to filter on regulation_id, and updated
ChunkBrowserQA to pass qdrant_id values.

New ChunkBrowserQA component replaces inline chunk browser with:
- Document sidebar with live chunk counts per regulation (batched Qdrant count API)
- Sequential chunk navigation with arrow keys (1/N through all chunks of a document)
- Overlap display showing previous/next chunk boundaries (amber-highlighted)
- Split-view with original PDF via iframe (estimated page from chunk index)
- Adjustable chunks-per-page ratio for PDF page estimation
Extracts REGULATIONS_IN_RAG and REGULATION_INFO to shared rag-constants.ts.

Fix A: Use _group_words_into_lines() with adaptive Y-tolerance to
correctly order words in multi-line cells (fixes word reordering bug).
RapidOCR: Add as alternative OCR engine (PaddleOCR models on ONNX
Runtime, native ARM64). Engine selectable via dropdown in UI or
?engine= query param. Auto mode prefers RapidOCR when available.

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.

- Chunks column now uses getKnownChunks() instead of API-based getRegulationChunks()
- Status column uses isInRag() check (green/red) instead of ratio-based calculation

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?"

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%
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- 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
