Remove 5 DELETE-category generator files identified in bf-1iefu:
- tests/fixtures/scanned/generate_scanned_fixtures.rs (Rust stub, use Python version)
- tests/fixtures/security/generate_sensitive_fixture.py (duplicate, Rust version preferred)
- tests/fixtures/encoding/generate_unmapped_glyphs.rs (superseded by Python version)
- tests/fixtures/malformed/gen-bomb-10k-2g.sh (superseded by Python version)
- tests/fixtures/forms/generate_form_fixtures.d (orphaned Makefile dependency)
Verification: No compiled object files (.o, .so, .a, .dylib, .dll) or executable binaries found. The .bin files in fixtures root are test data files, not compiled artifacts.
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
