Groundwork for hybrid search over the layout store: the dependencies and image payloads the
retrieval pipeline needs, the Docker changes to make rebuilding it cheap, and the first slice
of the element view that chunking will consume.

Dependencies

liteparse and chonkie, plus four transitive packages. liteparse 2.14 ships cp310-abi3
wheels for both manylinux arches, so the block extractor is no longer tied to one CPython —
the 3.12 default stays, but requires-python >=3.10 stays honest.

chonkie forces httpx>=0.28.1, which removes AsyncClient(app=...) and encodes json= with
allow_nan=False. Both conftests move to ASGITransport, and the three tests that
deliberately POST NaN metadata now send it via content= — otherwise the client rejects the
payload the server is supposed to 422 on.

Image

Two payloads are baked in so no first request has to fetch them: tesseract-ocr-eng for
liteparse's OCR path, and the DuckDB lance community extension. smoke_retrieval_deps.py
asserts all four in CI right after the existing CLI check.

Three things fell out of building it:

  • INSTALL lance cannot run at build time. A release builds linux/amd64,linux/arm64 on
    one amd64 runner via QEMU, and import duckdb segfaults under qemu-user — so the obvious
    RUN python -c "import duckdb; ... INSTALL lance" would have broken every multi-arch
    release. It is now a plain fetch that never loads the native module, proven in a single
    emulated x86_64 container where the script wrote the 254 MB amd64 extension while
    import duckdb core-dumped beside it.

  • The extension is native code the server loads in-process, so it is fetched over HTTPS and
    its sha256 checked against a per-version, per-platform pin before anything is written. Fails
    closed both ways: an unpinned duckdb version aborts the build, a digest mismatch writes zero
    files. (Roborev Critical, jobs #379/#382.)

  • The builder was defeating its own layer cache. COPY dist/*.whl sat above a single RUN
    that also did apt-get update/upgrade/install/purge, so the wheel — the only input that
    changes between builds — re-ran the whole apt cycle. Split apart, plus the uv Docker guide's
    UV_COMPILE_BYTECODE / UV_LINK_MODE=copy / UV_PYTHON_DOWNLOADS=0, uv 0.12.6, a
    bind-mounted wheel, and a .dockerignore. The 231 MB extension moved into its own stage
    above everything that varies per build.

Measured, on a genuinely-changed wheel: apt and venv layers now stay CACHED, the extension
layer stops churning, incremental rebuild 30s → 27s. Bytecode costs 150 MB and halves cold
start (importing extralit_server 23.0s → 12.5s), which is paid back on every worker start.
Image 1.55 GB → 1.94 GB, 231 MB of it the extension.

uv venv --seed, not uv venv. This originally read "drop it once
Extralit/extralit-hf-space#12 merges". #12 has merged, and the measurement says don't: removing
the seed does not remove pip, it makes pip fall through to the base image's
/usr/local/bin/pip, which installs into /usr/local/lib/python3.12/site-packages while
python stays /opt/venv/bin/python. A derived image doing pip install X then fails at
import rather than at install. The saving is 5.4 MB of 1847, so --seed stays.

Elements

elements_from_items reads the Lance items rows back as the three units a chunker dispatches
on, so chunking can re-run from the dataset without re-parsing the PDF. Decisions the rows
forced: one element per provenance row (a page-spanning item keeps two bboxes, text sliced by
charspan); captions absorbed by the nearest figure/table on the same page, either side;
uncaptioned figures produce nothing; page_header/page_footer dropped.

table_html replaces docling's exporter, which puts header <th> cells inside <tbody> — a
header a row-window chunk cannot find is one it cannot repeat. This changes the html value
on GET /documents/{id}/layout; no frontend reads it and the OpenAPI type is unchanged.

Verification

  • Unit suite 1993 passed. Three failures in test_jwt/test_settings are pre-existing and
    unrelated — confirmed identical on the pre-change lock (secret_key is 44 chars, the test
    asserts 32).
  • 21 new element tests; 156 passing across tests/unit/contexts/ocr.
  • Image built natively on arm64: smoke 4/4, CLI gate, no toolchain or /packages leakage.
    The amd64 image could not be built here (duckdb segfaults under emulation regardless of
    these changes); CI builds amd64 natively. CI's smoke step only exercises the native arch.
  • Both lance payload URLs confirmed to exist for amd64 and arm64.

Notes for review

  • The element commit is the first slice of a larger retrieval plan; the rest of that work is
    not in this PR.
  • .github/workflows gains one smoke step. The workflow still sets no buildx cache-from/
    cache-to, so none of the caching above applies on CI yet — worth doing separately, but
    mode=max on a 1.94 GB image risks the 10 GB Actions cache quota.

…nto the image

Phase 0 of the retrieval plan. liteparse 2.14 ships cp310-abi3 wheels for both
manylinux arches, so the block extractor no longer pins a single CPython — the
3.12 default from 270efb1 stays, but requires-python >=3.10 remains honest.

The image now carries the two things a first request must not have to fetch:
`tesseract-ocr-eng` (4 MB) for liteparse's OCR path and the DuckDB `lance`
community extension (231 MB), installed as `extralit` so it lands in the home
DuckDB resolves against. `smoke_retrieval_deps.py` asserts all four in CI right
after the existing CLI check; image grows 1.55 GB -> 1.8 GB, 92% of it the
extension binary.

chonkie requires httpx>=0.28.1, which removes `AsyncClient(app=...)` and encodes
`json=` with allow_nan=False. Both conftests move to `ASGITransport`, and the
three tests that deliberately post NaN metadata now send it as `content=` —
otherwise the client rejects the payload the server is supposed to 422 on.
A release builds linux/amd64,linux/arm64 on one amd64 runner via setup-qemu-action,
so the non-native stage runs under qemu-user — where `import duckdb` segfaults before
it can execute anything. `RUN python -c "import duckdb; ... INSTALL lance"` would
therefore have failed every multi-arch release build.

`install_lance_extension.py` reads the version from package metadata and downloads the
extension for the stage's own architecture, never loading the native module. Verified
both ways in one emulated x86_64 container: the script wrote the 254 MB linux_amd64
extension while `import duckdb` core-dumped beside it.

The extension CDN 403s the default Python-urllib agent, hence the explicit one.
`LOAD lance` in the smoke script is what proves the manual placement matches the path
DuckDB resolves.
The builder was one RUN that copied the wheel, then ran apt-get update/upgrade/install,
the install, and an apt-get purge. Because `COPY dist/*.whl` sat above it, a wheel change
— the only input that differs between two builds of the same tree — invalidated the whole
apt cycle. Measured on the same changed wheel: the old layout re-runs `python -m venv` and
the full apt install/purge; the new one keeps both apt layers and the venv CACHED and
re-runs only from the wheel COPY down.

apt now stands alone at the top of the stage, and gcc/libc6-dev are simply left there
rather than purged: the runtime image copies nothing out of the builder but /opt/venv,
so there is no toolchain to remove (verified absent from the final image).

From the uv Docker guide: UV_COMPILE_BYTECODE, UV_LINK_MODE=copy (the cache mount is a
different filesystem from /opt/venv), UV_PYTHON_DOWNLOADS=0, VIRTUAL_ENV, and the cache
mount moved to /root/.cache/uv to match UV_CACHE_DIR in a stage that has no extralit user.
Bytecode compilation costs 150 MB (1.8 -> 1.95 GB) and halves cold start: importing
extralit_server goes 23.0s -> 12.5s, paid back on every worker and every Space wake.

`uv venv --seed`, not `uv venv`: extralit-hf-space derives from this image and installs
into this venv with `pip`, which a default uv venv does not create.
…table header

First slice of Phase 1. `elements_from_items` is the inverse of `arrow.item_rows`: it reads
the Lance rows back as the three units a chunker dispatches on — markdown, table, figure —
so chunking can re-run from the dataset without re-parsing the PDF, and `contexts/retrieval`
never has to know a docling label.

Decisions the rows forced:
- One element per provenance row, not per item, so an item spanning a page break stays two
  elements with two bboxes instead of one claiming to be in two places. Text is sliced by
  charspan when an item has several provenances.
- Captions are consumed by the nearest figure or table on the same page, either side of it:
  nothing here links a PictureItem to its caption, and geometric parsers order them both ways.
  A caption with no figure on its page survives as prose rather than being dropped.
- An uncaptioned figure produces no element. There is nothing retrievable in it.
- page_header/page_footer are dropped; running furniture is repeated on every page and
  retrievable on none.
- Headings render as ATX markdown so the recursive chunker's line-anchored rules can split on
  them, and each element carries its breadcrumb. A title holds a slot above every section
  header whatever its level, so `Results` closes `Methods` without closing the title.

`table_html` replaces docling's exporter, which puts the header's `<th>` cells inside
`<tbody>` — a header a row-window chunk cannot find is a header it cannot repeat. The layout
API's `html` field changes shape with it; no frontend reads it and the OpenAPI type is
unchanged.
…v, drop the conda vars

The 231 MB extension was fetched in the final stage, below the venv COPY, so every one-line
code change rebuilt and re-exported it. It now has its own stage above everything that varies
per build: a wheel change leaves both the fetch and its COPY CACHED, and BuildKit runs the
fetch in parallel with the wheel install. Incremental rebuild 30s -> 27s locally, and the big
layer stops churning through the registry on CI.

That needs the duckdb version before the venv exists, so DUCKDB_VERSION is an ARG. The pin is
kept honest by `--check`, which compares it against the venv's resolved duckdb from package
metadata (no native import, so it survives the emulated arch of a release build) and fails the
build rather than shipping an image whose first hybrid search cannot find the extension.
Verified by building with a deliberately wrong pin.

Also: uv 0.7.12 -> 0.12.6; MAMBA_ROOT_PREFIX and CONDA_PREFIX dropped, vestiges of a
micromamba base that nothing in either repo reads; the wheel is bind-mounted rather than
copied, so no copy of it is left in the builder; and a .dockerignore allowlists the context
down to the wheel and two scripts.
Roborev, Critical, jobs #379 and #382. The build fetched a native DuckDB extension over
plaintext HTTP with no integrity check, and the server later loads that extension into its own
process — so anything able to answer for extensions.duckdb.org could put native code inside
the server.

The fetch is now HTTPS, and the decompressed payload's sha256 is checked against a pin kept per
duckdb version and target platform before a single byte is written. The two pinned digests were
confirmed against the extension already baked into a built image, not just against a fresh
download of themselves.

It fails closed in both directions: a duckdb version with no pinned digest aborts the build
rather than trusting whatever the repository serves, and a mismatch refuses to write. Verified
all three paths — happy path, unpinned version, doctored digest (zero files written).

Bumping DUCKDB_VERSION now also means adding a digest; `--digest` prints what the repository is
currently serving, to be confirmed independently before pinning.

Comment thread extralit-server/src/extralit_server/contexts/ocr/elements.py Outdated
Addresses CodeRabbit on PR #249, and it is a real loss. `_captionable` matches tables as well as
figures, so a caption next to a table was consumed out of the markdown stream — but the table
branch emitted only `row["html"]`, which never carried it. "Table 1. Prevalence by district."
disappeared from the document entirely, and a table's caption is usually the only prose saying
what the table is of.

The caption now folds into the markup as `<caption>`, escaped, as the first child of `<table>` —
the one position HTML allows it, so a row-window chunk can repeat it alongside the header. A
table that produced no markup keeps its caption as bare text rather than dropping both.

My own test is what let this through: it asserted the element *type* was `table` and never looked
at the content. It now asserts the retained text, joined by cases for caption placement, escaping,
and the no-markup fallback.
extralit-hf-space#12 merged as a05a1c0, so the pointer moves off the pin it had been stuck on
for ten commits.

That merge was supposed to unblock dropping `--seed` from `uv venv`, since hf-space no longer
installs with pip. Measured, it does not. Removing the seed does not remove pip from the image:
`pip` simply falls through to the base image's /usr/local/bin/pip, which installs into
/usr/local/lib/python3.12/site-packages while `python` stays /opt/venv/bin/python. So a derived
image running `pip install X` — exactly what hf-space did until yesterday — would install X
somewhere the interpreter cannot see it, and fail at import rather than at install.

The whole trade is 5.4 MB of 1847. Not worth handing that to the next person who extends this
image, so `--seed` stays and the comment now records the real reason rather than a dependency
that no longer exists.
`elements_from_items` walked the rows in Python to build breadcrumbs, bind captions
and render markdown — pulling every document's text out of Arrow to make strings that
went straight back into it. The projection is now `elements_sql`, one statement over
the `items` columns, and `elements_table` returns Arrow conforming to ELEMENT_SCHEMA.

The stack-based breadcrumb becomes three window functions per heading slot: a slot is
in scope only while the newest heading at or above it is still its own. Caption binding
becomes lag/lead over the document window, and the markdown/table/figure split a CASE.
Everything partitions by document_id, so a whole workspace projects in the pass that
used to do one document — 80k rows go 1.58s -> 0.32s, and the same query can run
against a Lance dataset with the scan filter pushed down.

Verified against the previous implementation on 400 randomised documents (captions,
page-spanning provenance, blank text, every label): identical output. One deliberate
divergence — heading levels past 6 now share the deepest slot instead of nesting,
since both render as `######` anyway.

The `Element` dataclass is gone; callers read columns. Nothing consumed it yet.
…with docling

Three things on this branch duplicated docling-core: an own `<thead>`/`<tbody>` table
serializer in arrow.py, a caption-to-figure geometry join and a label→markdown CASE in
elements.py. All deleted.

What replaces them, and what was checked (docling-core 2.91, chonkie 1.7):

- `append_blocks` now links each caption to the nearest table/picture on its page
  (`FloatingItem.captions`, back first: -1, +1, -2, +2). The parsers never populated
  `.captions`, which is the only reason the association was rebuilt downstream by geometry.
- `items` gains a `markdown` column: `MarkdownDocSerializer.serialize(item=…)` per item,
  with `escape_html=False`, `escape_underscores=False`, `image_placeholder=""` so a search
  index sees raw characters. A linked caption renders as `''` on its own and as a prefix of
  its owner, so it appears exactly once and the existing `content <> ''` filter drops it.
- `elements_sql` keeps only the breadcrumb windows, which docling gates behind the
  `chunking` extra (`transformers`). Content is `markdown`, except a page-spanning text
  item, which falls back to its charspan slice of `text`; NULL `markdown` (rows written
  before the column existed) falls back to `text` too.
- `html` stays and reverts to `item.export_to_html(doc=doc)`: it feeds the layout API
  (`LayoutItemOut.html`, OpenAPI contract) and keeps spans for the viewer; nothing chunks it.
- `LayoutStore._replace_one` widens a dataset written under an older schema with NULL
  columns via `add_columns`, so existing workspace datasets accept the appended rows.

Intentional behaviour changes: section headers render one level deeper (`## Methods`
for level 1, docling reserving `#` for the title); table content is caption + pipe
markdown, not `<table>` HTML; heading depth is no longer clamped at six in the content
(the breadcrumb slot still is). `TableChunker(chunk_size=2)` repeating caption + header
on every chunk is now pinned by a test, since we rely on chonkie for it.
Page-spanning rows are detected from the charspan alone (short of the whole text), which
drops the per-item count window; own_text, content and slot are lateral aliases in one
SELECT; the breadcrumb keeps two columns per slot (latest heading, depth of the latest
heading at or above) instead of three, and heading_level is the deepest slot's depth.
Single-consumer helpers folded into their callers.

Retain legacy table content during the markdown migration.

Schema widening leaves markdown null until each stored document is replaced. Line 80 ignores the existing html value, although the prior table projection used it. When a retained table row has empty text, content becomes empty and Line 107 removes the table from retrieval.

Backfill markdown for all stored rows, or fall back to html for legacy table rows.

In `@extralit-server/src/extralit_server/contexts/ocr/elements.py` at line 80,
Update the table content projection around markdown, coalesce(markdown,
own_text), and html so legacy rows with null markdown retain their existing html
content; alternatively, ensure the migration backfills markdown for every stored
row. Preserve retrieval of retained tables when text is empty and avoid the
downstream removal caused by an empty content value.

Delete contexts/ocr/elements.py and its test, and revert arrow.py and
layout_store.py (plus tests) to main: the items.markdown column, the
MarkdownDocSerializer at parse time, and the Lance schema-widening path
(_SQL_TYPES / _add_missing_columns) existed only to feed the element
projection. docling_core's HybridChunker derives everything that layer
computed from the stored DoclingDocument itself: heading breadcrumbs
(meta.headings), provenance back to items (meta.doc_items), caption
folding, furniture skipping and table row windows. link_captions in
docling_builder.py stays; it is the parse-time fix the chunker relies on.

Deps: drop chonkie (no remaining consumer). Add semchunk and
tree-sitter{,-python,-c,-javascript,-typescript} explicitly, since
docling_core.transforms.chunker imports them but only the [chunking]
extra declares them, and that extra also pulls in transformers, which we
do not want in the image. Smoke script now imports HybridChunker instead.
… it in the image

duckdb-extension-lance ships lance.duckdb_extension inside its wheel and pins duckdb to
the release it was built for, so the resolver now owns the version match that the
Dockerfile ARG and the --check script used to enforce. The image no longer fetches,
verifies or stages the extension; a consumer LOADs it by path from site-packages.

Drop the two build scripts and the CI smoke step with them. The only check they made
that no Python test covers, tessdata being present at TESSDATA_PREFIX, is now a one-line
assertion in the Dockerfile.
