When a user draws annotation boxes to mark OCR regions, the blocks are
created with source=MANUAL and empty text. upsertGuidedBlock was
protecting all MANUAL blocks unconditionally, so guided OCR silently
produced no output for these drawn-but-empty blocks.
Changed the guard to only protect non-empty MANUAL blocks — empty ones
are treated like OCR blocks and get their text filled in.

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

- 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

- POST /train in ocr-service with ZIP Slip validation, TemporaryDirectory,
ketos transfer learning, timestamped backups (keep last 3), in-process reload
- X-Training-Token auth (no-op in dev when TRAINING_TOKEN env is empty)
- trainModel() in OcrClient interface + RestClientOcrClient (10-min timeout,
multipart upload, forwards X-Training-Token when configured)
- TRAINING_TOKEN env var wired in docker-compose; --workers 2 in Dockerfile
so /health stays responsive during synchronous training

Added @JsonIgnoreProperties(ignoreUnknown = true) to OcrBlockResult so

OcrAsyncRunner was bypassing TranscriptionService — building blocks
directly and calling blockRepository.save(), skipping sanitizeText()
and saveVersion(). Also replaced N individual deleteBlock() calls with
a single bulk deleteAllBlocksByDocument() for OCR re-runs.

OcrService.startOcr() was setting scriptType on a detached entity,
silently losing the mutation. Added DocumentService.updateScriptType()

OcrController was injecting OcrJobRepository and OcrJobDocumentRepository

Replace the single extractBlocks() call with streamBlocks() that
processes pages incrementally. Each page's blocks are persisted
immediately via createSingleBlock(). Progress updates use the
ANALYZING_PAGE:current:total:blocks format. Per-page errors are
logged at WARN level without failing the entire job. The batch path
(processDocument) remains on the old extractBlocks() path.

Add streamBlocks() that POSTs to /ocr/stream and parses the NDJSON
response line by line with a dedicated ObjectMapper. Falls back to
the old /ocr endpoint via the default method when /ocr/stream returns
404. Uses a separate HttpClient with 5-minute request timeout for
streaming.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The default method synthesizes Start/Page/Done events from
extractBlocks() results, providing backward compatibility for
implementations that don't support streaming natively.

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.

The OCR service was getting 403 Forbidden because it tried to
download PDFs from MinIO using plain internal URLs without
authentication. MinIO buckets are private.
- Add S3Presigner bean to MinioConfig
- FileService.generatePresignedUrl(): generates 15-min presigned URLs
- OcrService uses presigned URLs instead of plain internal URLs
- Remove unused s3InternalUrl / bucketName @Value fields from OcrService

- BlockSource enum: MANUAL, OCR
- V26 migration adds source + reviewed columns to transcription_blocks
- OcrService sets source=OCR when creating blocks
- TranscriptionService.reviewBlock() toggles the reviewed flag
- PUT /api/documents/{id}/transcription-blocks/{blockId}/review endpoint
- 5 new tests: reviewBlock toggle/untoggle/notfound, controller,
OcrService source=OCR verification
The reviewed flag enables the Kraken fine-tuning pipeline: only blocks
marked as reviewed by a human are exported as training data.

OCR creates many adjacent text line annotations that would fail the

Two-pass title stripping with loop for stacked titles:
- Dot-prefixes (Dr., Prof.) matched without trailing space
- Word-prefixes (Tante, Frau, Schwester, etc.) matched at
word boundary
- Stacked titles like "Prof. Dr. Muller" handled correctly
- Single token after title strip goes to lastName (not firstName)
Add 5 "von" last names to KNOWN_LAST_NAMES for correct splitting
of entries like "Freifrau von Massenbach".
15 new test cases + updated 3 existing tests for title behavior.

Move paren extraction in parseReceivers() after the multi-separator
check so single-person entries like "Clara de Gruyter(*1871)" keep
their parens intact for split()'s annotation extraction. Multi-person
entries like "Hedi und Tutu (Gruber)" still use parens as shared
last-name override.

Extract trailing (...) content as annotation. Handles birth years
(*1871), nicknames (Tuttu), uncertainty markers (?), and uncertain
