fix(tables): stop dropping body-band scripts from the candidate set

Valid: the body-font pass filtered scripts out of body_candidates itself, so body_script_flags and its two downstream uses were dead. The mask filters region_evidence and feeds detect_table_in_region's is_script closure, but neither ever saw a script item because the candidate set no longer contained any. Consequences: a body-band sub/superscript attached to a heading-sized anchor was dropped from the table outright rather than assigned to a cell, so its text was lost — the opposite of what both the body_script_flags comment ('they stay candidates') and the detect_table_in_region docstring ('they remain eligible for cell assignment') describe, and inconsistent with the small-font pass. Root cause: the geometry rework removed the candidate-level filter from the small-font pass, but the body one had been reflowed onto a single line by rustfmt so the same edit missed it. Adding body_script_flags in a later review then wired a mask that the surviving filter made unreachable. No measured change on either benchmark — pdf-evals still 20 documents and -367 table rows, opendataloader still overall +0.0003 / mhs +0.0003 with one document changed — because the combination it affects (a body-sized script attached to a heading-sized anchor) does not occur in either corpus. The fix is for correctness and consistency between the two passes, not for a score. 964 tests pass, clippy clean.

-For context, engines that use OCR/ML (docling, marker, mineru) score 0.83-0.88 overall but take 2-180 minutes on the same corpus.
+Results were refreshed on July 31, 2026, on an Apple M4 Pro. Engine versions were pdf-inspector 0.2.6, LiteParse 2.10.1, OpenDataLoader 2.2.1, PyMuPDF4LLM 0.2.0, and MarkItDown 0.1.5. Speed is the median of five alternating or rotating complete corpus runs after an excluded warm-up run, with each parser processing documents sequentially in a single process.

-**Where we do well:** Speed (fastest of all engines), reading order, table detection vs other direct-text tools.
+The complete parser configuration, per-document predictions, evaluator output, and generated charts are available in the [reproducible results branch](https://github.com/firecrawl/opendataloader-bench/tree/abi/pdf-parser-benchmark-results).

-**Where we lag:** Heading detection trails opendataloader — many PDFs use bold text at body font size for headings, or headings that are only slightly larger than body text. Table detection trails OCR-based engines that can see visual table structure.
+**Best fit:** Native-text PDFs where speed, reading order, and table structure matter. In this comparison, pdf-inspector delivered the higher overall, reading-order, and table scores, along with the fastest complete run. That makes it a strong local default for reports, research papers, financial documents, invoices, and legal PDFs that need clean, structured Markdown without adding OCR latency or infrastructure.

+Use the [paired benchmark harness](docs/benchmarking.md) to compare two local builds against the exact same corpus and evaluator revision.

+# Benchmarking against OpenDataLoader
+
+The paired harness runs two `pdf2md` binaries through the same local
+OpenDataLoader corpus, evaluates both outputs, and reports aggregate and
+per-document deltas. This avoids comparing results produced from different
+corpus revisions or evaluator versions.
+
+Build a candidate and provide a released or worktree build as the baseline:
+
+```bash
+cargo build --release
+python3 scripts/bench_opendataloader.py \
+  --bench-dir ../opendataloader-bench \
+  --baseline ../pdf-inspector-main/target/release/pdf2md \
+  --candidate target/release/pdf2md \
+  --max-document-regression 0.02 \
+  --json-output /tmp/pdf-inspector-benchmark.json
+```
+
+Pass `--reference-evaluation path/to/evaluation.json` to report the candidate
+delta against another evaluation, and add `--require-reference-lead` to make a
+negative reference delta fail the run. By default, the candidate must not
+regress the baseline overall score or introduce missing predictions. Use
+`--min-overall-delta` to require a specific aggregate gain.
+
+The OpenDataLoader repository is external and keeps its normal
+`prediction/pdf-inspector` output. Paired evaluation copies each run into a
+temporary directory before evaluating it, so the baseline and candidate cannot
+overwrite one another.
+
+## Published comparison protocol
+
+The public benchmark table was refreshed on July 31, 2026, on an Apple M4 Pro
+using pdf-inspector 0.2.6, LiteParse 2.10.1, OpenDataLoader 2.2.1,
+PyMuPDF4LLM 0.2.0, and MarkItDown 0.1.5. Every engine processed the same 200
+PDFs sequentially in a single process with OCR disabled. Reported speed is the
+median of five alternating or rotating complete corpus runs after an excluded
+warm-up run; quality scores come from the benchmark evaluator over all 200
+outputs. Raw timings, predictions, evaluations, and charts are available in the
+[results branch](https://github.com/firecrawl/opendataloader-bench/tree/abi/pdf-parser-benchmark-results).
+
+## Optional backend evidence probe
+
+The evidence probe compares positioned `pdf2md` items with MuPDF structured
+text on the same pages. It is intended to find deterministic extraction or
+layout evidence that could justify a future native implementation; it does not
+merge MuPDF output into Markdown, invoke OCR, or add a runtime dependency.
+
+Install MuPDF's `mutool`, build `pdf2md`, then run:
+
+```bash
+python3 scripts/probe_backend_evidence.py document.pdf \
+  --pdf2md target/release/pdf2md \
+  --json-output /tmp/backend-evidence.json
+```
+
+The report flags pages when MuPDF exposes a material net token gain, repeated
+alignment anchors absent from local evidence, or additional image blocks. The
+JSON includes bounded token samples and page-level counts so promising cases
+can be inspected without treating backend disagreement as automatically
+correct. Thresholds are configurable with `--min-token-gain`,
+`--min-alternate-only-ratio`, and `--min-anchor-gain`.

+# Publishing
+
+The Rust crate is published to [crates.io](https://crates.io/crates/pdf-inspector) with trusted publishing from GitHub Actions. The first release was published manually; future releases publish from `.github/workflows/publish-crate.yml` when a `Cargo.toml` version change lands on `main`.
+
+## crates.io Trusted Publisher
+
+Configure the trusted publisher for the `pdf-inspector` crate with:
+
+- Repository: `firecrawl/pdf-inspector`
+- Workflow: `publish-crate.yml`
+- Environment: `crates-io`
+
+The workflow uses `rust-lang/crates-io-auth-action@v1` to exchange GitHub's OIDC token for a short-lived crates.io token, then passes it to `cargo publish`.
+
+## Release Steps
+
+1. Update `version` in `Cargo.toml`.
+2. Merge the version bump to `main`.
+3. The publish workflow compares the new `Cargo.toml` version with `HEAD~1`, runs `cargo publish --dry-run`, then publishes if that version is not already on crates.io.
+
+If `Cargo.toml` changes without a package version bump, the workflow exits without publishing.
+
+## Browser WebAssembly package
+
+The browser package is published as `@firecrawl/pdf-inspector-wasm`. Its version lives in `wasm/Cargo.toml`, and `.github/workflows/publish-wasm.yml` builds the `web` target with `wasm-pack` before publishing the generated package.
+
+The npm package must exist before a trusted publisher can be configured. For the first release only:
+
+1. Build with `wasm-pack build wasm --target web --scope firecrawl --out-dir pkg --release`.
+2. Inspect with `npm pack --dry-run ./wasm/pkg`.
+3. Publish with `npm publish ./wasm/pkg --access public` from an authorized maintainer session.
+4. In the package settings on npm, configure the GitHub Actions trusted publisher:
+   - Organization: `firecrawl`
+   - Repository: `pdf-inspector`
+   - Workflow: `publish-wasm.yml`
+   - Allowed action: `npm publish`
+
+After that one-time bootstrap, bumping the version in `wasm/Cargo.toml` and merging it to `main` publishes through OIDC. Until the package exists, the workflow exits cleanly without attempting an unauthenticated first publish. See npm's [trusted publishing documentation](https://docs.npmjs.com/trusted-publishers/) for the registry-side setup.

-# Rust API
+# pdf-inspector

-Add to your `Cargo.toml`:
+Fast PDF classification and text extraction. Detects whether a PDF is text-based or scanned, extracts text with position awareness, and converts to clean Markdown — all without OCR. Pure Rust, no ML models, no external services; the only PDF dependency is [lopdf](https://crates.io/crates/lopdf). Also available for [Python](https://pypi.org/project/pdf-inspector/) and [Node.js](https://www.npmjs.com/package/@firecrawl/pdf-inspector).
+
+Built by [Firecrawl](https://firecrawl.dev) to handle text-based PDFs locally in under 200ms, skipping expensive OCR services for the ~54% of PDFs that don't need them.
+
+## Features
+
+- **Smart classification** — TextBased / Scanned / ImageBased / Mixed in ~10–50ms, with a confidence score and per-page OCR routing.
+- **Markdown conversion** — headings, lists, code blocks, bold/italic, URL linking, and dual-mode table detection (PDF drawing ops + text-alignment heuristics).
+- **Layout-aware extraction** — multi-column reading order, position and font info per text item, RTL support.
+- **Robust text decoding** — CID/Type0 fonts via ToUnicode CMaps, plus automatic flagging of broken encodings so callers can fall back to OCR.
+- **Lightweight** — pure Rust, no ML models, no external services; single PDF dependency ([lopdf](https://crates.io/crates/lopdf)).

+## Install
+
+```bash

+```
+
+For the latest unreleased changes, use the git dependency instead:

 ```toml
 [dependencies]
 pdf-inspector = { git = "https://github.com/firecrawl/pdf-inspector" }
 ```

+The crate also ships CLI binaries — `pdf2md` (PDF → Markdown, with `--json`, `--pages`, `--select-pages`, and the opt-in token-saving `--compact` profile) and `detect-pdf` (classification, with `--analyze --json`):
+

+//! Text-quality detection: deciding when an extracted text layer is too broken
+//! to serve and a page should fall back to OCR.
+//!
+//! Extraction can produce plausible-looking bytes that are actually garbage —
+//! failed CID→Unicode mappings, broken ToUnicode CMaps, mojibake. These
+//! detectors catch that and let callers set `needs_ocr`. They come in two
+//! layers, sharing the same primitives:
+//!
+//! - **Markdown-level** ([`detect_encoding_issues`], [`is_garbage_text`],
+//!   [`is_cid_garbage`]) run on a page's final markdown string. Used as a
+//!   backstop on the region-extraction and whole-document paths.
+//! - **Item/span-level** ([`analyze_text_quality`],
+//!   [`region_items_have_decoding_issue`]) run on individual `TextItem`s and
+//!   accumulate per-page evidence, so localized garbled spans on an otherwise
+//!   clean page are caught without a single span having to condemn the page.
+//!
+//! Detection classes, roughly by signal:
+//! - **Replacement runs**: U+FFFD clusters ([`has_replacement_text_run`]).
+//! - **Private-use / C1-control runs**: CID passthrough landing in PUA or the
+//!   C1 block ([`has_private_use_text_run`], [`has_cid_control_token`]).
+//! - **Dollar-as-space**: `Word$Word$Word` from broken CMaps
+//!   ([`has_dollar_as_space_pattern`]).
+//! - **Non-alphanumeric dominance**: symbol soup ([`is_garbage_text`]).
+//! - **Substitution-cipher letter statistics**: pure-ASCII output whose letter
+//!   distribution is a permutation of natural language ([`CipherGarbleStats`]).

+## A Mathematical Theory of Communication
+
+### By C. E. SHANNON
+
+INTRODUCTION
+
+HE recent development of various methods of modulation such as PCM and PPM which exchange
+
+# Tbandwidth for signal-to-noise ratio has intensified the interest in a general theory of communication. A
+
+basis for such a theory is contained in the important papers of Nyquist¹ and Hartley² on this subject. In the present paper we will extend the theory to include a number of new factors, in particular the effect of noise in the channel, and the savings possible due to the statistical structure of the original message and due to the nature of the final destination of the information. The fundamental problem of communication is that of reproducing at one point either exactly or ap- proximately a message selected at another point. Frequently the messages have *meaning*; that is they refer to or are correlated according to some system with certain physical or conceptual entities. These semantic aspects of communication are irrelevant to the engineering problem. The significant aspect is that the actual message is one *selected from a set* of possible messages. The system must be designed to operate for each possible selection, not just the one which will actually be chosen since this is unknown at the time of design. If the number of messages in the set is finite then this number or any monotonic function of this number can be regarded as a measure of the information produced when one message is chosen from the set, all choices being equally likely. As was pointed out by Hartley the most natural choice is the logarithmic function. Although this definition must be generalized considerably when we consider the influence of the statistics of the message and when we have a continuous range of messages, we will in all cases use an essentially logarithmic measure. The logarithmic measure is more convenient for various reasons:
+
+1. It is practically more useful. Parameters of engineering importance such as time, bandwidth, number of relays, etc., tend to vary linearly with the logarithm of the number of possibilities. For example, adding one relay to a group doubles the number of possible states of the relays. It adds 1 to the base 2 logarithm of this number. Doubling the time roughly squares the number of possible messages, or doubles the logarithm, etc.
+2. It is nearer to our intuitive feeling as to the proper measure. This is closely related to (1) since we in- tuitively measures entities by linear comparison with common standards. One feels, for example, that two punched cards should have twice the capacity of one for information storage, and two identical channels twice the capacity of one for transmitting information.
+3. It is mathematically more suitable. Many of the limiting operations are simple in terms of the loga- rithm but would require clumsy restatement in terms of the number of possibilities. The choice of a logarithmic base corresponds to the choice of a unit for measuring information. If the
+base 2 is used the resulting units may be called binary digits, or more briefly *bits,* a word suggested by
+
+J. W. Tukey. A device with two stable positions, such as a relay or a flip-flop circuit, can store one bit of information. *N* such devices can store*N* bits, since the total number of possible states is 2
+*N* and log₂2 *N* = *N*. If the base 10 is used the units may be called decimal digits. Since
+
+log₂*M* = log₁₀*M*= log₁₀2 = 3:32 log₁₀*M*;

+
+a decimal digit is about 3 13 bits. A digit wheel on a desk computing machine has ten stable positions and therefore has a storage capacity of one decimal digit. In analytical work where integration and differentiation are involved the base *e* is sometimes useful. The resulting units of information will be called natural units. Change from the base *a* to base *b* merely requires multiplication by log*ba*. By a communication system we will mean a system of the type indicated schematically in Fig. 1. It consists of essentially five parts:
+
+1. An *information source* which produces a message or sequence of messages to be communicated to the receiving terminal. The message may be of various types: (a) A sequence of letters as in a telegraph of teletype system; (b) A single function of time *f* (*t*) as in radio or telephony; (c) A function of time and other variables as in black and white television — here the message may be thought of as a function *f* (*x*; *y*;*t*) of two space coordinates and time, the light intensity at point (*x*; *y*) and time *t* on a pickup tube plate; (d) Two or more functions of time, say *f* (*t*), *g*(*t*), *h*(*t*) — this is the case in “three- dimensional” sound transmission or if the system is intended to service several individual channels in multiplex; (e) Several functions of several variables — in color television the message consists of three functions *f* (*x*; *y*;*t*), *g*(*x*; *y*;*t*), *h*(*x*; *y*;*t*) defined in a three-dimensional continuum — we may also think of these three functions as components of a vector field defined in the region — similarly, several black and white television sources would produce “messages” consisting of a number of functions of three variables; (f) Various combinations also occur, for example in television with an associated audio channel.
+2. A *transmitter* which operates on the message in some way to produce a signal suitable for trans- mission over the channel. In telephony this operation consists merely of changing sound pressure into a proportional electrical current. In telegraphy we have an encoding operation which produces a sequence of dots, dashes and spaces on the channel corresponding to the message. In a multiplex PCM system the different speech functions must be sampled, compressed, quantized and encoded, and finally interleaved properly to construct the signal. Vocoder systems, television and frequency modulation are other examples of complex operations applied to the message to obtain the signal.
+3. The *channel* is merely the medium used to transmit the signal from transmitter to receiver. It may be a pair of wires, a coaxial cable, a band of radio frequencies, a beam of light, etc.
+4. The *receiver* ordinarily performs the inverse operation of that done by the transmitter, reconstructing the message from the signal.
+5. The *destination* is the person (or thing) for whom the message is intended. We wish to consider certain general problems involving communication systems. To do this it is first
+necessary to represent the various elements involved as mathematical entities, suitably idealized from their

+# @firecrawl/pdf-inspector-wasm
+
+Browser WebAssembly bindings for [pdf-inspector](https://github.com/firecrawl/pdf-inspector). Classify PDFs and extract structured Markdown locally from a `Uint8Array`, using the same Rust core as the native Node.js, Python, and Rust packages.
+
+## Install
+
+```bash
+npm install @firecrawl/pdf-inspector-wasm
+```
+
+## Usage
+
+```ts
+import init, { processPdf } from "@firecrawl/pdf-inspector-wasm";
+
+await init();
+
+const response = await fetch("/annual-report.pdf");
+const pdf = new Uint8Array(await response.arrayBuffer());
+const result = processPdf(pdf);
+
+console.log(result.pdfType);
+console.log(result.markdown);
+```
+
+Pass options when you need selected pages or compact Markdown:
+
+```ts
+const result = processPdf(pdf, {
+  pages: [1, 3, 5],
+  profile: "compact",
+  includePageMarkers: true,
+});
+```
+
+The package also exports:
+
+- `detectPdf(pdf, options?)` for detection without extraction.
+- `classifyPdf(pdf)` for the lightweight result shape shared with the native Node.js API.
+- `extractText(pdf)` for plain text.
+- `version()` for the WASM package version.
+
+## Browser behavior
+
+- Parsing runs locally. PDF bytes are not uploaded anywhere.
+- The build is single-threaded and does not require cross-origin isolation.
+- CMaps are embedded so CJK font decoding does not depend on a filesystem.
+- Extraction is synchronous after `init()`. For large documents, call it from a Web Worker to keep the UI responsive.
+- Image-only documents still require a separate OCR step.
+
+## Build from source
+
+```bash
+cargo install wasm-pack --version 0.15.0 --locked
+wasm-pack build wasm --target web --scope firecrawl --release
+```
