jedarden d0f52751ce fix(pdftract-39gey): fix indent trigger to not split drop-cap paragraphs 
The indent trigger was using .abs() which fired on both increased indent
(non-indented → indented) AND decreased indent (indented → non-indented).
This caused drop-cap style paragraphs (indented first line, flush-left
continuation) to incorrectly split into two blocks.

Per plan Phase 4.4 heuristic #2, indent change should only trigger when the
current line is MORE indented (to the right, larger x0) than the block
average - i.e., a new paragraph starting after non-indented text. It should
NOT trigger for decreased indent (first line indented, rest flush-left).

Fix: Remove .abs() and only check if line_x0 - block_avg_x0 > threshold.

Tests:
- test_indented_first_line_new_block: PASS (non-indented → indented splits)
- test_indented_first_line_of_paragraph_not_split: PASS (drop cap stays together)
- All 179 line module tests: PASS

JSON Schema Validation Test Fixtures

This directory contains PDF files used for JSON schema validation testing per bead pdftract-3jm4n (Phase 6.1.4).

Each PDF in this directory is extracted and validated against the published JSON schema at docs/schema/v1.0/pdftract.schema.json. Any validation error fails CI.

Adding Fixtures

To add a new fixture:

  1. Place the PDF file in this directory
  2. Name it descriptively (e.g., simple-text.pdf, multi-page.pdf)
  3. The test harness will automatically pick it up

Current Fixtures

  • simple-text.pdf - Minimal text-only PDF for basic validation
