[Refactor] DoclingDocument as the OCR layout contract - #240
Merged
Conversation
Replaces the two disconnected OCR paths with one parser-agnostic seam that
persists layout with real lineage: every item carries a ProvenanceItem
(page_no + bbox + charspan), so an extraction record can cite its source
region.
Parsers are swappable behind `contexts/ocr/parsers`:
- pdf_inspector (MIT, zero deps, required) — the always-available default.
Normalizes its three quirks at the boundary: inconsistent page indexing
across its own API, bottom-left coordinates, and no page dimensions (read
from MediaBox with pikepdf). Structure-tree roles joined on (page, mcid)
yield real heading levels and table regions on tagged PDFs.
- pymupdf (AGPL, optional `pymupdf` extra) — higher fidelity; the only one
that yields per-cell table geometry. Kept optional so the Apache-2.0
distribution never requires an AGPL dependency.
The three tolerant scrapers become single-item appenders driven by one
ordered pass, which fixes the duplication (text inside tables was emitted
twice) and the lost reading order. Tables and pictures are added first so
containment dedup can run, then body order is restored geometrically.
Layout persists as canonical DoclingDocument JSON in S3 plus a columnar
Parquet projection (one row per (DocItem, ProvenanceItem), so multi-page
items expand naturally). Not documents.metadata_ — that column is returned
in full by every GET /documents.
Adds GET /documents/{id}/layout returning a flat projection rather than the
raw DoclingDocument, whose 73 recursive $defs would make OpenAPI and
hand-written frontend types unusable, plus the matching frontend entities
and repository method.
Deletes, rather than migrates: the marker extra (marker-pdf, torch,
torchvision, transformers), async_marker_layout_job, the deprecated
Unstructured-shaped chunks.py, and the unreferenced GPU_QUEUE.
Test fixtures are generated by tests/fixtures/pdf/generate.py using only
pikepdf, including a tagged variant that exercises the mcid path; the
blanket **/*.pdf ignore is narrowed so they can be committed.

…preprocessing Two HIGH findings from review #335. The layout route authorized with DocumentPolicy.get(), which carries an explicit unfixed TODO and returns true for any annotator. Since the document is loaded by UUID, an authenticated user from another workspace could read its extracted text, table HTML, and page geometry. Adds DocumentPolicy.get_by_workspace, following the existing WorkspacePolicy.get pattern, and applies it once the document's workspace is known. The shared get() is left alone — its TODO predates this work and affects sibling routes. The layout job was enqueued alongside analysis_and_preprocess_job, which runs OCRmyPDF rotation and overwrites the PDF at the same S3 path. Layout could therefore describe the pre-rotation file while clients render the post-rotation one, persisting bounding boxes for a PDF nobody displays. It now depends on the analysis job. The metadata_ read-modify-write also takes a row lock, since the external text-extraction job still writes that JSON column concurrently. Adds 10 regression tests covering both.

…e runs Text extraction and layout now depend on the preprocessing job with Dependency(allow_failure=True): preprocessing rewrites the PDF at the same S3 key as its last step and writes the margins both readers need, while rotation itself is best effort — without allow_failure a failed triage would strand both dependents in DEFERRED forever. Retry and result_ttl move onto Queue.prepare_data(); the @job decorator values are inert on this path, so finished jobs expired after RQ's 500s default and the derived workflow status decayed back to pending. Job ids carry the run suffix, so a forced restart no longer collides with the previous run's ids, and POST /workflows/start?force=true stops started jobs and cancels pending ones from the old group before enqueueing the new one.
The per-document Parquet sidecars were shaped for writing one document at a
time: a corpus question meant globbing thousands of ~7.6 KB objects, and a
re-parse left both vintages' rows behind because nothing superseded them.
Layout rows now go into one `layout/items.lance` and `layout/pages.lance` per
workspace. A document's rows are deleted before they are appended, so a re-parse
replaces rather than doubles, and the rows are queryable the moment the job
commits — `duckdb_connection([workspace, ...])` exposes both as views with
projection and filter pushdown.
Because replacing is a delete commit plus an append commit, every writer holds a
Redis lock keyed on the resolved workspace root; Lance's own commit conflict
detection is the belt to that lock's braces. The layout job takes the lock,
confirms the document row still exists, writes, releases, and only then updates
`documents.metadata_` — through `update_processing_metadata`, which all writers
of that JSON column now share, so no job can clobber another's slice.
Where a workspace lives is resolved in exactly one place, `files.workspace_root`,
which PDFs, thumbnails, layout JSON and the Lance roots all address through, so
switching to one bucket with `{org}/{workspace}/` prefixes later is a change to
that function rather than to every call site. Bucket versioning gets a lifecycle
rule expiring noncurrent `layout/` versions, replacing the dead
EXCLUDED_VERSIONING_PREFIXES.

…iage functionality This commit introduces a new documentation file detailing the PDF preprocessing configuration for the Extralit Server, specifically focusing on the rotation-only processing using OCRmyPDF. It outlines the settings available via environment variables, the workflow during PDF uploads, and troubleshooting tips. Additionally, a new triage functionality is implemented to classify PDF structures without performing OCR, identifying pages that require OCR and providing metadata about the document's layout. This enhances the overall document processing workflow by ensuring that structural analysis is performed efficiently before any preprocessing steps. The changes also include updates to the metadata models to accommodate the new triage results and adjustments in the document processing jobs to integrate the triage step effectively.

- Line 27: Change the PREPROCESSING_ENABLED configuration entry heading from
level 4 to level 3, preserving the existing heading text and hierarchy under the
level-2 heading.
In `@extralit-server/src/extralit_server/contexts/files.py`:
- Around line 417-454: Update create_bucket so only the create_bucket call
handles BucketAlreadyOwnedByYou and BucketAlreadyExists as a successful
existing-bucket case; then continue unconditionally to put_bucket_versioning and
put_bucket_lifecycle_configuration for both new and existing buckets, while
preserving error propagation for other creation failures.
In `@extralit-server/src/extralit_server/jobs/document_jobs.py`:
- Around line 114-119: Update PreprocessingMetadata and
DocumentProcessingMetadata.update_preprocessing_results() to preserve
rotation_ran and error from preprocessing_result when serializing document
metadata, matching the PDF preprocessing configuration contract. Add an
assertion verifying both fields remain present in the serialized
documents.metadata_ value.
- Around line 127-128: Update the job flow around update_processing_metadata in
the document processing handler to treat a None return as cancellation and stop
before reporting completion. Coordinate the metadata check with PDF and
thumbnail object writes so deletion winning the race prevents stale workers from
recreating artifacts, while preserving normal processing for existing documents.
- Around line 102-109: Update the document job flow around files.put_object and
the metadata commit near the analysis/preprocessing persistence step so the
rewritten PDF is not published until its matching metadata is durable. Use the
metadata write as the completion boundary, then expose the processed PDF
consistently with that protocol; preserve the existing processing data and
metadata contents.
In `@extralit-server/src/extralit_server/jobs/ocr_jobs.py`:
- Around line 95-103: Update the layout-storage flow in the OCR job so
storage.store_layout’s canonical JSON upload occurs before entering
store.locked(). After acquiring the workspace lock, perform the
document-existence check and Lance replacement; if the document was deleted,
remove the newly uploaded artifact before returning the skipped result.

send_stop_job_command only asks a worker to stop, so `force=true` could enqueue a replacement while the previous run was still alive — and that stale run would then overwrite the new one's rotated PDF, layout JSON, Lance rows and metadata. Every artifact writer now checks a generation token before it writes: the job's own workflow_id against the document's newest DocumentWorkflow row. The layout job checks it inside the workspace lock next to its existence check; the analysis job checks it just before the thumbnail and the PDF rewrite. A superseded run returns early and writes nothing. A job with no workflow in its meta is always current, so direct calls are unaffected. Fixes roborev #341 (HIGH). #342 (swallowed artifact-cleanup failures) is answered in its comment: the leak is negligible and the durable-outbox fix is deferred by plan, so the docstrings now say the failure is ignorable.
Silent-failure fixes:
- Layout filters never reached the server. Axios serializes arrays as `pages[]=2`,
but the endpoint declares `pages: list[int] = Query(...)`, which binds only
repeated bare keys, so FastAPI dropped every filter without erroring.
`paramsSerializer: { indexes: null }` restores `pages=2&pages=3`.
- `binary_hash` used `hash(pdf_bytes)`, which Python salts per process, so the
same PDF hashed differently across workers. Replaced with a shared
`content_hash()` on xxh3_64 — ~10x faster than sha256 and, unlike the
truncated digest it replaces, fills `DocumentOrigin.binary_hash`'s full Uint64.
- `create_bucket` let `BucketAlreadyOwnedByYou` escape to the outer handler,
so pre-existing workspace buckets never picked up versioning or the layout
lifecycle rule — exactly the version growth the rule was added to bound.
- `PreprocessingMetadata` dropped `rotation_ran` and `error`, which the job
computes and the admin guide documents, leaving a failed rotation invisible.
- `analysis_and_preprocess_job` wrote the PDF, thumbnail and metadata for a
document deleted mid-run, then reported success. Now guarded on both sides,
mirroring the pattern already in `ocr_jobs.py`.
Also: `filename` added to the `LayoutParser` protocol (both parsers take it and
the job passes it); unknown `layout_parser` rejected at the API boundary rather
than deep inside the queued job; single-pass tagged/untagged partition in
pdf_inspector, replacing an O(n^2) scan that also dropped spans comparing equal;
explicit `pyarrow.compute` import that only worked via a docling_core side
effect; fixture path and heading levels in docs.
Not adopted from the review: frontend bbox origin normalization (the builder
already flips everything to TOPLEFT before it becomes provenance), and running
the layout job through an async-aware worker (RQ 2.4.1's `Job._execute` already
awaits coroutine job functions).

is_current_workflow_run and the document job write sequence: prevent workflow
replacement from racing with shared S3/metadata writes, or stage artifacts under
a workflow-generation-specific location and atomically promote them only if that
generation remains current. Do not rely on adding another standalone current-run
check, since it leaves the same time-of-check-to-time-of-use window.

The fixture returned `None` from `get_current_job`, so the job under test computed `workflow_id=None` and the superseded assertion passed on a mock forced to return False regardless of its arguments. Dropping the token entirely would still have gone green; it now fails.

Description
This PR replaces Extralit's two disconnected OCR paths with a single parser-agnostic seam, and adopts
DoclingDocumentas the canonical internal layout model.The problem. The live path (
extralit_ocr.jobs.pymupdf_to_markdown_job) emits a flat markdown string with no bounding boxes at all. The dead path (async_marker_layout_job) had zero callers, was commented out ofpreload.py, sat onDEFAULT_QUEUEdespite being the OCR job, took a localPathwhen the worker is fed S3 URLs, and persisted nothing. Three near-identical tolerant scrapers each re-sniffedtype|block_type|category|labelandbbox|coordinates|bounding_box|rect|boxin three independent passes — losing reading order and duplicating text that sits inside tables and figures — feeding a deprecated Unstructured-shaped model that nothing imported.Net effect: nothing linked extracted text back to a page region, so an extraction record could never cite its source.
The fix.
DoclingDocument'sProvenanceItemis exactly the lineage triple we need —page_no+bbox+charspan. Layout now persists as canonical JSON plus a columnar Parquet projection, and is served over a new read API whose types are threaded into the frontend for a future provenance overlay.Parsers are swappable
pdf_inspectorcp38-abi3wheels for manylinux x86_64 and aarch64pymupdfpymupdfextraLicensing is the deciding factor:
extralit-serveris Apache-2.0, so PyMuPDF must never become a required dependency of the PyPI distribution. The hf-space bundle already installspymupdf4llm~=0.0.27, so it satisfies the extra at deploy time.Three
pdf_inspectorquirks are normalized at the adapter boundary and nowhere else:TextItem.pageandStructureElement.pageare 1-indexed;PdfClassification.pages_needing_ocris 0-indexed.TextItem.yis bottom-left origin, so every bbox is flipped viato_top_left_origin.pikepdf(already a transitive required dep viaocrmypdf— no new dependency).mcid+StructureElement.rolejoined on(page, mcid)is what yields realadd_heading(level=N)values and table regions on tagged PDFs.Ordering and duplication
Tables and pictures are added first so containment dedup (
BoundingBox.intersection_over_selfat 0.6) can drop text they already contain — then body order is restored geometrically. Captions and footnotes are exempt, since they legitimately overlap their figure.Storage
Canonical JSON in S3 plus two Parquet sidecars, one row per

Deliberately notdocuments.metadata_— thatJSON()column is returned in full by everyGET /documentsviaDocumentListItem.metadataand would bloat list responses. The schema is Lance-native, soindex/lancedb_engine.pycan ingest it unchanged when cross-document provenance search is wanted.Deleted, not migrated

Reviewer notes — three things worth a look
.gitignorehad a blanket**/*.pdfthat silently swallowed the new test fixtures. Without the narrow un-ignore added here, CI would fail withFileNotFoundErrorwhile passing locally.Reading order is fixed beyond the dedup pass. The docling-eval ordering (tables/pictures first) leaves every table ahead of every paragraph in the body.
sort_body_by_positionrestores true geometric order afterwards, soexport_to_markdown()reproduces the page as a reader sees it.One deviation from the plan:
LayoutBlock.htmlwas dropped. It had no producer and no consumer —TableItemrenders HTML from its cells and has nowhere to store a parser-supplied string. Thehtmlcolumn inITEM_SCHEMAis unaffected and populated.Known limitation:
pdf_inspectordetects tables only on tagged PDFs — it has no ruling-line detection — so on the untagged fixturepymupdffinds the table andpdf_inspectordoes not. This matches the design intent (pymupdf is the high-fidelity parser) but means the required-dep default is weaker on untagged scans.Follow-up, not in this pass: once a
DoclingDocumentexists,export_to_markdown()reproduces whatpymupdf_to_markdown_jobandTextExtractionMetadata.markdownprovide today — that job becomes redundant and should be folded into the layout job rather than maintained alongside it.Summary by CodeRabbit
