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. Unsupported pages or image formats may be refused or reported with limitations; recognized text is not merged with extracted text.
Documentation
Updated usage and capability information with OCR support and its limitations.
Testing
Added OCR fixture checks across Linux, Windows, and macOS platforms.
…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 eligible scanned PDF pages and PNG or JPEG files. It adds a separate OCR process, recognition-aware profile and representation data, extraction and CLI integration, and related tests, CI checks, benchmarks, and documentation.
Changes: OCR v3
Layer / File(s)
Summary
OCR profile and representation contracts crates/ethos-parser-core/*, crates/ethos-parser-pdf/src/nodes.rs, crates/ethos-parser-pdf/src/represent.rs, docs/draft-schemas/*, docs/PUBLIC-API.md
Profiles now record whether OCR is pinned and can include the recognizer identity. Recognized text runs carry image-pixel provenance and use a recognized locator. Structural validation rejects recognized text on a page that also contains extracted text. Schemas, exports, and Markdown locator access support the new representation.
OCR executable and image processing ocr/*, .gitattributes
Adds the separate ethos-parser-ocr workspace, model assets, image and PDF-image decoding, recognition pipeline, process protocol, and fixture tests. The vendored rten-vecmath provides SIMD operations used by the runtime. Git attributes disable end-of-line conversion for OCR models and test data.
PDF and image extraction crates/ethos-parser-pdf/src/*, crates/ethos-parser-office/tests/erasure_counters.rs
PDF extraction selects pages with no text-showing operators and exactly one loaded image placement, then passes eligible images to the recognizer. Recognized words become text runs with image provenance. PNG and JPEG inputs can be extracted as one-page documents. Refusals and OCR limitations are recorded, and identity mismatches and recognizer errors fail extraction.
CLI and recognizer process wiring crates/ethos-parser-cli/src/*, crates/ethos-parser-cli/tests/*
Adds --ocr to extraction and source-based Markdown commands. The CLI discovers the recognizer through ETHOS_PARSER_OCR or beside its executable, then exchanges JSON requests and responses with the process. Tests cover OCR output, missing recognizers, and image refusal messages.
CI and OCR documentation .github/workflows/ci.yml, ci/*, CHANGELOG.md, README.md, docs/*
Adds pinned-toolchain OCR checks and platform test jobs. Updates the v3 roadmap, OCR scope and capability documentation, and CLI guidance.
ParseBench OCR 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. Documentation reports OCR benchmark results, score-reuse timing, and held-out split measurements.

Security architecture risk: Moderate · up to 07106
OCR is explicitly opt-in and keeps recognized text separate from extracted text. However, crafted scanned PDFs can trigger image expansion without a corresponding memory limit, potentially interrupting processing and creating host memory pressure. Executable ownership and runtime isolation remain deployment assumptions.
Retained concerns
Medium · security · inferred: The new OCR PDF-image decoder has no effective decompressed-byte budget. An eligible scanned PDF supplies compressed image bytes that are expanded into an unrestricted buffer before sample validation or a named refusal. Source-size and page-count limits do not bound this expansion. Crafted documents can therefore exhaust recognizer memory and abort extraction; wider host impact depends on deployment resource isolation.
Security review details
Security Blast Radius
inferred — An attacker able to supply a document to an OCR-enabled caller can influence image bytes, filters, and dimensions processed by the recognizer. The established impact is resource consumption in that processing context; shared-host availability exposure depends on external limits. No remote endpoint, cross-tenant authority gain, or credential access was established.
Security Findings and Attack Paths
inferred — The retained architecture concern follows document-controlled compressed image bytes through PDF request construction and the subprocess protocol into unrestricted Flate expansion. Exhaustion occurs before sample validation can return a refusal. The CLI source cap and existing content budgets do not impose a decoded-image ceiling.
Trust Boundaries and Controls
observed — Executable discovery occurs before document processing and does not use document bytes. The integration invokes fixed identity and serve commands without document-derived command arguments. Whether the environment variable and executable location are exclusively operator-controlled remains a deployment proof gap, not an established executable-injection finding.
Resilience and Maintainability Implications
observed — The adapter does not validate response version or request-id correlation. The built-in recognizer echoes the current request id and processes requests synchronously, so no document-driven cross-request substitution was established. Correlation remains an implicit dependency contract rather than an enforced adapter invariant.
Hardening Proposals
proposed — Define and enforce encoded-byte, per-filter expansion, predictor-row, and raster-area budgets before allocation, using checked arithmetic and named resource refusals. Complement these with per-worker memory and execution limits so process separation also provides resource containment.
proposed — Document trusted ownership of executable selection and deployment isolation. Validate response version and request id before accepting an answer, and discard the serving session on protocol violations rather than relying solely on the built-in peer's behavior.

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.

- 359:
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.

Review comment at @docs/00-NORTH-STAR.md at line 203:
Update the “What done means” table so v3 is OCR under its own profile and v4 is
Propose-only VLM assist, matching decisions #15 and #120. Revise the v4 gate
wording to reflect that the pinned profile hash satisfies the
fingerprint-comparability requirement, and keep the section’s trailing paragraph
consistent with the updated roadmap.

Decision 120: OCR, as v3. One commit,
4981a00.extract --ocrandmarkdown --source --ocrread text no text layer carries. OCR moves ahead of assist, so it is v3 and assist v4.ethos-parser-ocr. Each word it reads is atext_runof derivationrecognized, under the OCR profile, which pins the recognizer's identity. A page that needs OCR and is not read is counted underscanned-page-not-recognizedwith its reason. The seal refuses a page that holds both extracted and recognized text.--ocrit is refused by name;groundrefuses 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.recognizer: not_pinnedfield. With that hash masked, the gate's 8 documents and opendataloader-bench's 200 extract byte-identical to0e4eade; under--ocrthey hold the same nodes.--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-platformocr-platformsjob.Merge by fast-forwarding main locally, not with the merge button, which would add a commit under another author.
