fix(read_extract): dedupe DOCX text-box text in _extract_docx

[JiataiWang]

Fixes #67851.

Problem

read_file on a .docx containing a text box (or any block-level content control) emitted the text-box contents twice.

Root cause

A Word text box stores its content as <w:p> paragraphs inside <w:txbxContent>, so paragraphs can nest. _extract_docx did:

for para in root.iter(f"{w}p"):        # recursive: also yields the NESTED <w:p>
    for node in para.iter():           # recursive: also descends INTO the nested <w:p>
        if node.tag == f"{w}t":
            ...

ElementTree.iter() walks the whole subtree, so the outer paragraph pulled the box's <w:t> in inline and the nested <w:p> was visited independently — emitting the same text twice.

Fix

ElementTree has no parent pointers, so build a child → parent map and attribute each text node to its nearest enclosing <w:p>. Text owned by a nested paragraph is skipped in the ancestor and emitted only when that paragraph is visited on its own. Each <w:p> now contributes exactly one line and each run of text appears once.

Documents without nested paragraphs are unaffected (the nearest <w:p> of every text node is its own paragraph, exactly as before).

Testing

• Failing-first: the new test_text_box_not_duplicated fails on main (AssertionError: 2 != 1) and passes with this change.
• Full file suite: python -m pytest tests/tools/test_read_extract.py → 19 passed.
• Manually verified: plain paragraphs, tabs, and line breaks are byte-for-byte unchanged; a doubly-nested text box (box-in-box) extracts each fragment exactly once in document order.

Thanks for the focused regression test and for tracing the duplicate to recursive paragraph traversal. The bug remains on current main at tools/read_extract.py:118-126.

Problems

• The new ownership filter at tools/read_extract.py:146 skips BOXTEXT while the outer paragraph is emitted first (:138), then emits the nested paragraph later. For this PR's fixture (tests/tools/test_read_extract.py:170-174), that changes source order from Before → BOXTEXT → After to Before After → BOXTEXT.
• tests/tools/test_read_extract.py:177-180 only checks uniqueness and presence, so it does not catch that reordering.

Suggested changes

• Preserve the fixture's source/document order while eliminating the duplicate, and assert the resulting full output or relative fragment order in the regression test.

[JiataiWang]

Rebased onto current main (a4a91610) and resolved the test-file pruning conflict without restoring removed tests. The review feedback is now covered by a single document-order walk: nested text-box content remains in Before → BOXTEXT → After order, with a relative-order regression assertion. Canonical runner: scripts/run_tests.sh tests/tools/test_read_extract.py -q — 12/12 passed. The PR is mergeable again.

Summary

Two open PRs touch OOXML extraction, but only #67853 addresses issue #67851's nested-paragraph duplication: its document-order walk emits text-box content once without reordering it, whereas #61881 adds archive resource limits and leaves paragraph traversal unchanged.

Related pull requests

• fix(security): harden backup import and OOXML extraction #61881 related — (+412/-28) — n/a: The diff hardens backup import and OOXML ZIP handling with resource limits, collision checks, streaming extraction, and external-provider confinement, but does not change the recursive DOCX paragraph traversal that causes [Bug]: DOCX text-box (nested-paragraph) text extracted twice by read_file #67851. Consistent with the keep_open review on fix(security): harden backup import and OOXML extraction #61881, this independently relevant security work should remain separate.
• fix(read_extract): dedupe DOCX text-box text in _extract_docx #67853 best fix — (+58/-8) — best fix: The current diff replaces recursive paragraph extraction with a single document-order walk and tests both one-time emission and Before → BOXTEXT → After → Tail ordering. Despite the visible keep_open review on fix(read_extract): dedupe DOCX text-box text in _extract_docx #67853, its stated ordering concern is addressed by the current implementation and relative-order assertions.

Suggested consolidation

Keep #67853 open with a salvage path: retain its focused document-order traversal and uniqueness/order regression test as the best existing fix for #67851 while routing it through normal backlog review. Keep #61881 separate for its archive-hardening scope; it is not a duplicate of #67853.
