feat(ocr): a scanned page and an image file are read by a pinned recognizer, decision 120 - #53
extract --ocr and markdown --source --ocr read text no text layer carries. OCR moves ahead of assist, so it is v3 and assist v4.
A page that shows no text and places exactly one image is read by ethos-parser-ocr. Each word it reads is a text_run of derivation recognized, under the OCR profile, which pins the recognizer's identity. A page that needs OCR and is not read is counted under scanned-page-not-recognized with its reason. The seal refuses a page that holds both extracted and recognized text.
A PNG or JPEG file is one page, its own pixel grid, and the source is the file. Without --ocr it is refused by name; ground refuses it (decision 16).
ocr/ is the recognizer, its own workspace on Rust 1.98.0: PP-OCRv5 mobile on rten 0.26, with sums made order-fixed in a vendored rten-vecmath, so it answers the same bytes on Linux x86-64 and arm64, Windows x86-64 and macOS arm64 and x86-64. An x86-64 CPU without AVX2 and FMA is refused by name. The models are committed (12.7 MB, Apache-2.0) and built in.
The default profile's hash moved for its new recognizer: not_pinned field. With that hash masked, the gate's 8 documents and opendataloader-bench's 200 extract byte-identical to 0e4eade; under --ocr they hold the same nodes.
ParseBench with --ocr: 52.10 -> 53.91, 74 pages up and none down. The scope's 55.0 bar is missed and recorded as amended.
Checked locally: every test binary and doc test (across two runs), clippy, cargo deny, the Node (96/96) and Python (117/117) SDK suites, and ci/ocr.sh. The full gate did not finish in one run, so this PR is for CI: every job, including the PR-only gates and the five-platform ocr-platforms job.
Merge by fast-forwarding main locally, not with the merge button, which would add a commit under another author.
Summary by CodeRabbit
New Features
Added opt-in OCR for scanned PDF pages containing one supported image, plus PNG and JPEG files treated as one-page documents. Use --ocr with extraction or source-based Markdown projection.
OCR results include recognized text and image locations under a distinct profile. Unsupported pages or image formats may be refused or reported with limitations; recognized text is not merged with extracted text.
Documentation
Updated usage, capability, and OCR reference information with supported inputs and limitations.
Added benchmark results and details about optional ParseBench score reuse.
Testing
Added OCR fixture checks across Ubuntu x86-64 and arm64, Windows, and current and Intel macOS runners.
…gnizer, decision #120
`extract --ocr` and `markdown --source --ocr` read text no text layer carries.
OCR moves ahead of assist, so it is v3 and assist v4.
- A page that shows no text and places exactly one image is read by
`ethos-parser-ocr`. Each word it reads is a `text_run` of derivation
`recognized`, addressed by a new locator variant, `recognized`, under the
OCR profile, which pins the recognizer's identity. A page that needs OCR
and is not read is counted under `scanned-page-not-recognized` with its
reason. The seal refuses a page that holds both extracted and recognized
text.
- A PNG or JPEG file is one page, its own pixel grid, and the source is the
file. Without --ocr it is refused by name; `ground` refuses it (#16).
- `ocr/` is the recognizer, its own workspace on Rust 1.98.0: PP-OCRv5
mobile on rten 0.26, with sums made order-fixed in a vendored
rten-vecmath, so it answers the same bytes on Linux x86-64 and arm64,
Windows x86-64 and macOS arm64 and x86-64. An x86-64 CPU without AVX2 and
FMA is refused by name. The models are committed and built in.
- The default profile gained `recognizer: not_pinned`, so its hash moved.
With that hash masked, the gate's 8 documents and opendataloader-bench's
200 extract byte-identical to 0e4eade's; under --ocr they hold the same
nodes.
- ParseBench with --ocr: 52.10 -> 53.91, 74 pages up and none down. The
scope's 55.0 bar is missed and recorded as amended.
- CI: the gate's tenth step runs `ci/ocr.sh`; the `ocr-platforms` job runs
the recognizer's fixtures on five runners.

This pull request adds OCR support for scanned PDF pages and PNG or JPEG inputs. It adds OCR profile data, recognized-run provenance, a separate OCR runtime, extraction and CLI wiring, CI checks, benchmark support, and documentation and schema updates. It also adds opt-in ParseBench score reuse.
Profiles now record recognizer pin state and identity. Recognized runs carry image provenance and a recognized locator. Structural checks enforce recognized-run constraints. Schemas, exports, and documentation describe these changes and the v3 OCR lane.
OCR runtime and model assets ocr/*, .gitattributes
Adds a separate ethos-parser-ocr workspace, pinned toolchain, model assets, image and PDF-image decoding, recognition pipeline, process protocol, and fixture tests. Git attributes disable end-of-line conversion for OCR model and fixture data.
PDF and image extraction crates/ethos-parser-pdf/src/*, crates/ethos-parser-core/src/assurance.rs, crates/ethos-parser-office/tests/erasure_counters.rs
Adds OCR candidate selection, image-file extraction, recognized-run placement, OCR limitations, and the outside-visible-word counter. PDF extraction records refusals and mismatches and rereads eligible pages with recognized words.
CLI and recognizer process wiring crates/ethos-parser-cli/src/*, crates/ethos-parser-cli/tests/*
Adds --ocr to extraction and source-based Markdown. The CLI discovers and drives the recognizer process. Tests cover Markdown output equivalence, missing recognizers, refusal messages, and schema artifacts.
CI and OCR documentation .github/workflows/ci.yml, ci/*, CHANGELOG.md, README.md, docs/*
Adds OCR checks to CI and updates user guidance, scope and capability documentation, roadmap records, schemas, and public API documentation.
ParseBench score reuse
Layer / File(s)
Summary
Engine OCR benchmark mode and score ledger docs/measurements/parsebench/*, CHANGELOG.md
Adds an engine OCR benchmark mode and an opt-in score ledger keyed by scorer-input SHA-256. The benchmark documentation records OCR measurements, score-reuse timings, and held-out split results.

Security architecture risk: Moderate · up to 110c2
Opt-in OCR introduces an unbounded decompression path for document-supplied images. A crafted scanned PDF can exhaust memory during processing. Explicit opt-in and provenance checks reduce exposure, but do not bound resource use.
Retained concerns
Medium · security · inferred: The new OCR boundary bypasses existing decoded-content budgets. A textless PDF page placing one axis-aligned image can supply a Flate stream that expands far beyond its declared raster requirements. The worker expands the entire stream into a growing vector before sample validation, allowing an untrusted document to exhaust worker memory and potentially pressure the host. A separate process does not itself impose a memory quota.
Security review details
Security Blast Radius
inferred — An attacker needs control of a document processed with OCR, not control of the recognizer executable, to reach the unbounded expansion. The directly supported impact is exhaustion of the OCR invocation's resources; competing workloads could be affected if host resources are shared without quotas. No tenant-wide, network-wide, or privileged-access impact is established.
Security Findings and Attack Paths
inferred — A qualifying scanned page can declare a small grayscale raster while carrying a highly compressible Flate stream with excessive decoded output. OCR forwards that stream to read_to_end before checking samples. This is new exposure: the base image-attribute path hashes stored bytes without decoding the image. The conclusion is source-derived, not an executed exhaustion test.
Trust Boundaries and Controls
observed — Controls separate recognized text from native extraction: profile and answer identities must match, PDF answer dimensions must match, and representation validation prohibits mixed recognized and extracted text on a page. MCP's default-only callers do not activate the new OCR worker. None of these controls bounds decompression.
Resilience and Maintainability Implications
observed — Normal shutdown closes worker stdin and waits; the built-in worker exits on EOF. However, response reads and cleanup waits have no deadline or forced termination in this adapter, so cleanup depends on worker cooperation. Decode errors normally become named refusals, whereas allocation exhaustion is not converted into such a refusal.
Hardening Proposals
proposed — Establish a bounded OCR resource contract: cap output during each decompression stage, validate checked raster and predictor sizes before allocation, and define worker memory and execution limits with bounded termination and reaping.
proposed — Validate response protocol version and request id before attaching results to a page. The built-in worker currently echoes these correctly, but the consumer only deserializes them; explicit binding would strengthen the configurable recognizer contract without treating operator-selected executables as untrusted document input.

A recognized word whose box crosses the page edge makes the whole document fail.
Drawn runs pass through the D4-S5 guard at Lines 893-900. That guard turns a box outside the page into MeasuredOffPage, because seal refuses any measured box outside its page. Recognized runs skip this guard and always carry GeometryPresence::Measured(w.rect).
recognize::place filters words only by their box centre against the visible box. A word near the page edge can have its centre inside the page and its box partly outside. This happens with an image that is larger than the page, or a crop box equal to the media box. That word reaches to_representation, and the seal refuses the entire document. The image-file path has the same exposure if a recognizer quad lies slightly outside the raster.

…a predictor row past u32 refuses its page, decision #120
Two findings from PR 53's review, each a whole document failing where one
word or one page should have been set aside.
- A recognized word whose centre is on the page and whose box runs past
its edge reached the seal as a measured box outside the page, and the
seal refused the document. Recognized runs now take the guard drawn
runs take: the word keeps its text and its pixels, and its box is
`measured_off_page`. ParseBench's `text_ocr__cramer` was refused this
way under --ocr, a box ending at x = 59716 on a page 59528 wide; it is
read now, and ParseBench with --ocr moves 53.91 -> 53.94, 75 pages up
and none down.
- The recognizer multiplied a predictor row's colours, bits and columns
in u32: /Columns 536870912 at 8 bits wrapped to a row of no bytes, and
`chunks_mut(0)` panicked, which stopped `serve` and failed the
document. The product is checked now, and a row past u32 or of no
bytes refuses its page as `predictor-not-read:size`.
Each has a test that fails without its fix.

…t, and a held-out split is measured and not built, decision #121
Two lessons from articles on extraction pipelines, measured on the stored
ParseBench runs of the last six decisions before either was built.
- `ETHOS_BENCH_LEDGER=<dir>` (opt-in) stores each result under the
SHA-256 of what ParseBench's scorer receives: the test case, the
output, ParseBench's commit and uncommitted diff, its arguments; less
the run's clock and the four fields every engine version changes. An
example whose inputs repeat takes the stored result. Between
decisions 93-97% of examples repeat, scoring is half to two thirds of
a run, and none of 13,225 repeated outputs ever scored differently.
Checked against fresh scoring: filling an empty ledger, 0 of 2,553
apart; reusing it under --ocr after PR 53's fix, only the page the fix
reads differs, and scoring took 38 s instead of 298.
- A fixed 30% of documents held out from every census never disagreed
in sign with the full set, could not resolve a typical +0.1 decision
(any 30% spans 0.00 to 0.21 by chance), and read 7-67% lower than the
rest on all six for what it holds, not tuning. Not built; pages up and
down stay the check.
- The adapter's README pins ParseBench at 1f5b37a, where its numbers
were measured, and states a full run as measured: about eight minutes.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Fail clearly when the ParseBench checkout is not a git work tree.
_git runs with check=True at import time. If ParseBench is installed as a package and not as a git checkout, _git("rev-parse", "HEAD") raises CalledProcessError. The error has no hint that ETHOS_BENCH_LEDGER is the cause. git missing from PATH raises FileNotFoundError in the same way.
The ledger is opt-in, so the impact is limited to runs that set it. Catch the error and raise a message that names the ledger and the required checkout. The same ledger path also derives the repository root with parents[3]. Verify that this holds for an editable uv sync install.

Keep successful scores when a ledger write fails.
If the ledger directory is read-only or full, _ledgered can lose a successful score. The worker path omits that score from the aggregate. The multi-task path can abort the evaluation. Catch ledger write errors, report them, and return the score.

Update the successful-result ledger write in _ledgered to catch OSError from
directory creation, part-file writing, or replacement and report the failure.
Preserve and return the successful score even when the ledger write fails so
worker aggregation and multi-task evaluation can continue.

…failed ledger write keeps its score, decision #121
Two findings from PR 53's second review, both in the score ledger:
- An entry that would not read raised before the scorer ran, which
failed the example in ParseBench's process pool and stopped its
multi-task path. It is a miss now: scored again and stored whole.
- A write that failed (a full disk, a read-only directory) raised after
the scorer ran, so a successful score was lost and the pool counted
the example failed, a silently wrong aggregate. The score stands now,
nothing is stored, and stderr says so.
Checked with a stored ParseBench result in a scratch ledger: reuse, a
truncated entry, a read-only ledger. Without the fix the truncated
entry raises.

Update the v4 row to match decisions #15 and #120.
Decisions #11, #15 and #120 renumber the roadmap. OCR is now v3 and assist is v4. The ## 5. What "done" means table still lists v3 as "Propose-only VLM assist" and v4 as OCR under its own profile. The same section's trailing paragraph still says "v3 and v4 are still one line each". Readers of the table get the pre-#120 order, which contradicts row 15.
Swap the v3 and v4 rows, or add an "Amended by row 120" note to each. Check the gate wording too. The old v4 gate was "fingerprint provably incomparable", which row 120 meets through the pinned profile hash.

…eans, decision #120
PR 53's third review: row 120 renumbered the roadmap, OCR v3 and assist
v4, but section 5's table still listed them the other way round, and
the paragraph under it still said both were one line each. The rows are
swapped, each saying what it was until row 120; v3's done-when is met
by row 120, since the OCR profile pins its recognizer and so hashes
apart from the default; v3 has its scope document now and v4 does not.

Bound Flate output before allocating it.
A scanned page can declare a small image but contain a highly compressible Flate stream that expands far beyond its dimensions. decode::pdf reads the entire expansion into memory before checking the samples. This can exhaust memory and terminate the recognizer, ending extraction instead of recording a page refusal. Limit each Flate expansion and return a named refusal when it exceeds the limit.

…defines it, decision #120
PR 53's fourth review read "a born-digital parse" as a born-digital
document read under --ocr, which shares the OCR profile's hash with a
scanned one, and asked for the artifacts' identities to change. Contract
section 6 rule 4 makes the run the unit: an OCR run has a different
profile_sha256, so its output is non-comparable with a born-digital
parse "with no new machinery". The row now says so; nothing in the
engine changes.

…cision #120
PR 53's fifth review: an image file's alpha was dropped, so black text on
a transparent black ground decoded all black and read as nothing. A file
with alpha is now composited over white, as a viewer shows it, in
integers so every CPU agrees; a file without alpha decodes as before, and
the recognizer's byte-identity fixtures, RGB files, are unchanged. A test
fails without the compositing.

…ame, decision #120
PR 53's sixth review: a scanned page's image went to the recognizer with
its /SMask dropped, so black text masked onto a black image arrived all
black and the page read as nothing, with no reason given. The protocol
carries one image and no mask, so such a page is now refused by name
under `scanned-page-not-recognized`: `soft-mask-not-read`, and
`mask-not-read` for a /Mask, whose stencil could otherwise let text no
viewer shows be read.
ParseBench with --ocr is unchanged: 0 of 2,553 examples scored
differently. A test fails without each check.
