Summary

Adds .wps (WPS Writer / Microsoft Works text) and .et (WPS Spreadsheet)
to the recognized extensions, routing them to the existing Doc and Excel
parsers respectively.

Modern WPS Office exports these as OLE2 compound files carrying the same
content streams their Microsoft counterparts mandate — WordDocument for
.wps, Workbook/Book for .et. anydoc's content-based detection
(from_bytes) already recognizes them by stream name; this change only
extends extension-based detection (from_extension / from_path) so files
named .wps or .et convert correctly without a rename.

Changes

• src/lib.rs — register "wps" => Format::Doc and "et" => Format::Excel
  in Format::from_extension; update the Format::Doc and Format::Excel
  doc comments to note the shared-stream WPS wrappers.
• README.md — list .wps under Word and .et under Excel in the
  supported-formats table.

No new parser, no new Format variant: both extensions reuse the existing
binary Word (formats/doc) and spreadsheet (formats/sheet via calamine)
frontends.

Why no binding changes

The Node / wasm / Python Format enums are public API surface. Since .wps
and .et reuse the existing Doc/Excel parsers, format_from_extension("wps")
correctly returns the existing Doc / Xlsx variant already exposed. Adding
new enum values would break JS/Python callers that branch on these strings,
so they are intentionally left unchanged.

Scope

Covers modern WPS Office / Microsoft Works .wps and modern WPS .et — the
OLE2-based variants with standard content streams. Legacy WPS 2000-era private
binary containers (no standard streams) are out of scope and degrade safely:
detection returns None/Unsupported rather than panicking.

Verification

• cargo fmt --check ✅
• cargo clippy -p anydoc --all-targets -- -D warnings ✅
• cargo test -p anydoc — 208 unit + 8 snapshot + 1 robustness, all green ✅
• Confirmed Format::from_extension returns Doc for wps/WPS and
  Excel for et/ET (case-insensitive); existing mappings unchanged.

Confidence score: 2/5

• python/pyproject.toml changes both the PyPI distribution name and import package, breaking existing installs and the documented import anydoc. Revert the rename or update the public API and all callers.
• src/formats/docx/ole.rs uses an untrusted FAT count as an allocation capacity before checking the file size, so a tiny malformed OLE file can exhaust memory. Bound the count before allocating.
• src/formats/docx/ole.rs can also allocate over 16 million slots for sparse BIFF cells from a small stream. Enforce a grid-slot budget or keep cells sparse.
• rk_value in src/formats/docx/ole.rs decodes negative RK integers incorrectly because the shift does not sign-extend, producing incorrect cell values. Shift the signed value instead.

<file name="src/shared/list.rs">

<violation number="1" location="src/shared/list.rs:100">
P2: Hoisting the orphan run as sibling lists lets it merge with the following ordered list in Markdown. `join_block_parts` separates two `List` blocks with only a single newline, so `1. deep1\n2. deep2` and `6. shallow` form one list and `6.` renders as `3.`. Previously the anonymous bullet kept them apart. Consider emitting a separator (for example an HTML comment) between adjacent ordered lists in the renderer.</violation>

<violation number="1" location="src/model/table.rs:115">
P2: `expanded()` copies the origin's content into every covered slot with no byte budget. A merged region can cover up to 4M positions, so one small DOCX with a large merged cell can multiply its text millions of times on the `dedup_cells=false` path. The ODF repeat path bounds the same amplification with `MAX_EXPANSION_TEXT_BYTES`; charge the copied bytes here too and return `ResourceLimit` when the budget is exceeded.</violation>

<violation number="1" location="python/anydoc_sznb/__init__.py:39">
P2: `to_markdown_with_images` is re-exported raw, so it has no `ocr="hosted"` path. A scanned PDF raises `NeedsOcrError` here, while `to_markdown_bytes` falls back to Firecrawl. Wrap it with the same OCR handling, or document that the image variants do not support hosted OCR.</violation>

<violation number="2" location="python/anydoc_sznb/__init__.py:44">
P3: None of the new Python surface is tested: `to_text_bytes`, the two `*_with_images` functions, `ExtractedImage`, `ImagesResult`, or the new keyword passthrough. Add unittest cases to `python/tests/test_anydoc.py` that check the keywords change output and that the result classes expose their fields.</violation>

<file name="src/render/markdown/escape.rs">

<violation number="1" location="src/render/markdown/escape.rs:16">
P2: After this change, `EscapeOpts`' four trailing and line-start fields are never read, and `Delims::contains` has no callers. The struct-level `#[allow(dead_code)]` hides this. The trailing-context computation in `inline.rs` (`delims_ahead`, `delims_of`) is now wasted work. Remove the unused fields and their callers, or drop the allow so the compiler reports them.</violation>

<file name="src/render/markdown/inline.rs">

<violation number="1" location="src/render/markdown/inline.rs:161">
P2: The PR is titled and described as adding `.wps`/`.et` detection, but this file changes Markdown output for every document. Links, bold, and line breaks are rewritten with no mention in the PR description. Either split these rendering changes into their own PR or describe them explicitly.</violation>

<violation number="2" location="src/render/markdown/inline.rs:169">
P2: The empty-label fallback emits the raw URL without escaping. A `|` in a table cell will split the row, and `*`, `_`, `<` or control characters in the URL are emitted as live Markdown. Route the URL through `escape_url_as_text` as before.</violation>

<violation number="3" location="src/render/markdown/inline.rs:339">
P2: This change breaks existing assertions in `src/render/markdown/tests.rs`. Bold no longer emits `**`, hard breaks no longer emit `\`, and links no longer emit `[label](url)`. Update those expectations, or the test suite stays red despite the PR claiming all tests pass.</violation>

P2: The sector shift comes straight from untrusted header bytes and is not validated. Shifts of 64 or more panic in debug builds.

P2: A reversed `MERGEDCELLS` range underflows here because `then_some` evaluates its span argument eagerly. Validate endpoint ordering before calculating spans so malformed input cannot panic or produce wrapped dimensions.</violation>

<violation number="10" location="src/formats/docx/ole.rs:460">
P3: The comment says the spec uses a two-byte flags field. The single-byte `segs.u8()` read matches MS-XLS XLUnicodeRichExtendedString, so the comment is wrong and misleads future readers. Describe the actual layout instead of a corpus-specific claim.</violation>

<violation number="11" location="src/formats/docx/ole.rs:512">
P2: The MULRK comment and the `else if blen >= 8` branch describe a layout that is not in MS-XLS.

P3: The comment says the spec uses a two-byte flags field. The single-byte segs.u8() read matches MS-XLS XLUnicodeRichExtendedString, so the comment is wrong and misleads future readers. Describe the actual layout instead of a corpus-specific claim.

• src/formats/ppt/mod.rs resets the stack-depth check for each table cell, so deeply nested table groups can recurse until stack overflow. Carry the current depth through captured walks or enforce a separate nesting limit.
• src/formats/ppt/mod.rs only checks overlap at a new cell’s origin, so a rectangle can cover an earlier cell’s origin and shift that cell into a later column. Reject rectangles whose full grid area intersects owned.
• src/formats/ppt/mod.rs drops text from unanchored children when other cells form a successful grid. Preserve those blocks or fall back when loose children contain text.
• src/formats/ppt/mod.rs can overflow on extreme i32 coordinates in the subtraction and snap’s (b - edge).abs(), causing a panic or incorrect result. Widen both differences to i64.
