Both training panels (OCR and segmentation) share TrainingHistory.
Show only the 3 most recent runs by default; render a Mehr/Weniger
anzeigen button when there are more.

- Add tabindex="0" so the SVG can receive DOM focus
- Auto-focus the SVG on mount so arrow keys work immediately after
clicking an annotation to select it
- Show preview rect during keyboard nudging (not just pointer drag) by
checking hasLiveChanges instead of only checking dragState
- Suppress default browser focus outline (outline: none) on the SVG

Extends the 4-corner L-bracket handles with 4 tick-mark edge handles
(short lines along each edge), enabling single-axis resize from any edge.
Updates applyHandleDrag to route each handle to the correct axis.

- 4 corner-only handles (nw/ne/sw/se), no edge midpoints
- Each handle renders as two short perpendicular lines meeting at the corner
(10px arms, navy, square linecap) — no fill, no box
- Thin dashed selection border added to SVG overlay to signal edit mode
- Simplify applyHandleDrag to remove dead n/s/e/w branches

ResizeObserver binds actual SVG pixel dimensions; viewBox matches them so
16px handle squares and 44px hit areas are physically correct regardless of
the annotation's aspect ratio.

Commit 5afdc37 changed the empty state from transcription_empty_cta
('Markiere einen Bereich…') to transcription_empty_draw_hint
('Zeichnen Sie Bereiche…') but left the spec asserting the old text.
Updated the locator to match the current component output.

WCAG 1.4.1 (Use of Color) requires non-color redundant cues for status.
The unicode ✓/✗ characters had inconsistent screen-reader support.
Replaced with explicit aria-hidden SVG icons (checkmark / x-circle)
alongside the translated status text labels.

TranscriptionEditView rendered 'Kurrent-Erkennung' and 'Segmentierung'
as hardcoded German strings, breaking the en/es locales. Added
training_chip_kurrent and training_chip_segmentation keys to all three
message files and wired them up via m.training_chip_kurrent() /
m.training_chip_segmentation().

Screen readers did not announce page-by-page OCR progress updates.
Wrapping the counter text in a span with aria-live=polite ensures
assistive technology announces each page completion without
interrupting the user.

Drawing annotations is now the primary workflow. OCR only runs on
manually drawn regions (guided mode always). Full-page layout detection
and the useExistingAnnotations checkbox are removed entirely.
- OcrTrigger: guided-only, disabled with hint when no annotations exist
- TranscriptionEditView: empty state shows draw-regions instruction,
OCR trigger moved out of collapsible and shown inline after block list
- i18n: add ocr_trigger_no_annotations, ocr_section_heading,
transcription_empty_draw_hint; remove ocr_use_existing_annotations keys

Kraken 7 removed support for the legacy `path` format (image + .gt.txt
pairs) in VGSLRecognitionDataModule despite the CLI still advertising it.
Switching to PAGE XML (-f page) format which is the supported standard.
- Java export now writes .xml alongside .png (PAGE XML with TextLine,
Baseline at 75% height, and Unicode transcription)
- XML special characters in transcription text are escaped (& < >)
- Python trainer globs *.xml and passes -f page to ketos train
- Regenerated frontend API types to include cer/loss/accuracy/epochs on
OcrTrainingRun (were missing, causing empty CER column in history)
- Updated and extended TrainingDataExportServiceTest

kraken.ketos has no .train or .segtrain attributes in Kraken 7 — both are
only exposed as CLI commands. Rewrites both training functions to invoke
`ketos train` / `ketos segtrain` via subprocess and parse the best
val_metric from checkpoint filenames.
Also fixes the OcrTrainingCard history so it only shows non-blla runs
(recognition model), matching SegmentationTrainingCard which already
filtered to blla-only.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
After each training run, the Character Error Rate (CER = 1 - accuracy),
loss, accuracy, and epoch count are now stored on the OcrTrainingRun
record and shown in the training history table.
Also adds the missing POST /api/ocr/segtrain endpoint and the
triggerSegTraining service method so the segmentation training card
can actually trigger training.

The parent was manually remapping availableSegBlocks → availableBlocks
before passing props, which broke after the card was updated to read
availableSegBlocks directly. Pass the full trainingInfo object instead.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Both cards were reading the same availableBlocks field, so the segmentation
box always showed the kurrent recognition count. Use the correct
availableSegBlocks field from the training info response.

Historical letter lines often intersect, so the system must support
overlapping annotation regions. Removed the overlap guard from
createAnnotation(), deleted ErrorCode.ANNOTATION_OVERLAP, and cleaned
up all tests and frontend error mappings that referenced it.

When a document has manually drawn annotation boxes, the user can now
enable "Nur annotierte Bereiche" in the OCR trigger panel. The engine
skips layout detection entirely and runs recognition only within the
pre-drawn bounding boxes, preserving manual transcription blocks.
- Python: adds OcrRegion model, extend OcrRequest/OcrBlock; guided
branch in /ocr/stream groups by page and crops each region
- Engines: add extract_region_text() to both Kraken and Surya
- Java: adds OcrBlockResult.annotationId, OcrClient.OcrRegion,
TriggerOcrDTO.useExistingAnnotations; OcrAsyncRunner dispatches to
upsertGuidedBlock when annotationId is present; OcrService threads
the flag through to runSingleDocument
- TranscriptionService: adds upsertGuidedBlock (creates, updates OCR,
or preserves MANUAL blocks)
- Frontend: guided OCR toggle in OcrTrigger shown when blocks exist;
skips destructive-replace confirmation in guided mode

- Add /segtrain endpoint to OCR service (ZIP upload, ketos.segtrain,
backup rotation, in-process model reload)
- Add segtrainModel() to OcrClient and RestClientOcrClient (10-min timeout,
X-Training-Token header)
- Add SegmentationTrainingExportService: PAGE XML export with polygon
de-normalization and per-page PNG rendering via PDFBox
- Add GET /api/ocr/segmentation-training-data/export endpoint
- Make TranscriptionBlock.text nullable for segmentation-only blocks
(V31 migration)
- Add Paraglide i18n translation keys for all training UI strings (de/en/es)
- Pass source prop from TranscriptionEditView to TranscriptionBlock
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Convert TrainingHistory, OcrTrainingCard, SegmentationTrainingCard, and
TranscriptionBlock "Nur Segmentierung" badge to use Paraglide message keys
- Add availableSegBlocks to TrainingInfoResponse to expose segmentation
block count in the training info endpoint
- Wire SegmentationTrainingCard into admin/system page below OCR training card
- Update api.ts with availableSegBlocks field

Shows 'X / Y geprüft' with a brand-mint progress bar at the top of the
transcription panel. Derived from the blocks prop — no extra state.

Changed OcrTrigger and ScriptTypeSelect from 'import * as m' to
'import { m }' to match the rest of the codebase. Increased
ScriptTypeSelect label to text-sm and annotation badge font to 12px
for better readability.

The retry button set status='running' but didn't re-trigger the $effect
because jobId hadn't changed. Added retryCount state so the effect
re-runs and creates a fresh EventSource on retry. Also added aria-label
to the progress bar for accessibility.

The skipped-pages warning is inlined directly in +page.svelte.
The component and its tests are no longer needed.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The progress message already says "Seite 3 von 7 wird analysiert…"
so the separate "3 / 7" counter was redundant. Remove the
OcrProgressBar from the page and inline only the skipped-pages
warning.

The thin bar without a border looked broken at low progress values.
The text counter (e.g. "1 / 6") already communicates progress clearly
so the bar is unnecessary.

Add a collapsible OCR trigger below the block list in edit mode.
Uses a <details> element so it's unobtrusive — the primary workflow
is editing existing blocks, but users can expand to re-run OCR with
a confirmation dialog that warns about replacing existing blocks.

Replace inline translateOcrProgress with the extracted module. Add
OcrProgressBar below the spinner during OCR. Parse page numbers from
ANALYZING_PAGE progress codes and feed them to the bar. On Done, fill
bar to 100% briefly before clearing the overlay.

Progress bar shows brand-mint fill on brand-sand background with

Move translateOcrProgress from page.svelte to a testable module.
Return structured result with currentPage/totalPages/skippedPages
for the progress bar. Add ANALYZING_PAGE and DONE with skipped pages
parsing. Add i18n keys for de/en/es.

OCR engines are CPU-bound and were blocking Uvicorn's single async
event loop, making /health unresponsive during processing. This caused
new OCR requests to fail silently (health check failure → no DB record
→ UI shows NONE). Wrap engine calls in asyncio.to_thread() to keep the
event loop free. Also surface OCR trigger errors in the frontend
instead of silently resetting the spinner.

Prevents users from drawing annotations that would be cleared when
the OCR job finishes. transcribeMode is set to false for the PDF
viewer while ocrRunning is true.

Backend sends progress codes (PREPARING, LOADING, ANALYZING,
CREATING_BLOCKS:N, DONE:N, ERROR) via OcrJob.progressMessage.
Frontend translates them via Paraglide (de/en/es) and displays
below the spinner.
- V27 migration: adds progress_message column to ocr_jobs
- OcrAsyncRunner updates progress at each phase
- Poll interval reduced to 2s for snappier updates

Single-document OCR now creates an OcrJobDocument row so
GET /api/documents/{id}/ocr-status can find running jobs.
OcrAsyncRunner updates the job document status (RUNNING → DONE/FAILED).
Frontend checks OCR status when entering transcription mode —
if a job is running, resumes polling and shows the spinner.

OcrService → OcrAsyncRunner was circular. Fixed by moving all OCR
processing logic (processDocument, clearExistingBlocks, createBlocks)
into OcrAsyncRunner. OcrService is now a thin entry point that
validates, creates the job, and dispatches to OcrAsyncRunner.
Architecture:
- OcrService: validates document, checks health, creates OcrJob, delegates
- OcrAsyncRunner: @Async processDocument + runSingleDocument + runBatch
- OcrBatchService: creates job + job documents, delegates to OcrAsyncRunner
- No circular dependencies
Single-document OCR is now async (returns jobId immediately).
Frontend polls GET /api/ocr/jobs/{jobId} every 3s until DONE/FAILED.
816 backend tests pass, 687 frontend tests pass.

Prevents 'can't access property innerHTML, textDiv is null' when

- triggerOcr captures jobId from POST response and shows OcrProgress
- OcrProgress rendered in the transcription panel when ocrJobId is set

- Review checkmark toggle on each TranscriptionBlock (turquoise when
reviewed, muted outline when not). Calls PUT .../review to toggle.
- TranscriptionBlockData type: added source + reviewed fields
- +page.svelte: triggerOcr() and reviewToggle() functions wired up
- Paraglide translations (de/en/es) for review toggle + reviewed count
All 687 frontend tests pass.
