- Remove unused import `crate::span_flags::flags` from span/mod.rs - Add verification note confirming span text assembly implementation is complete The span text assembly logic was already implemented in merge_glyphs_to_spans: - assemble_text appends each glyph's codepoint to span.text - Word boundaries append " " to the PREVIOUS span (option a from plan) - Multi-codepoint glyphs (ligatures) are handled by Phase 2 expansion - RTL text is preserved in source byte order for Phase 4.2 bidi reordering All acceptance criteria tests exist and pass.

Verification Note: pdftract-2c5sx (Span Text Assembly)
Summary
Implemented span text assembly logic for Phase 4.1 glyph-to-span merging.
Implementation
1. assemble_text Function (lines 339-341)
fn assemble_text(span: &mut Span, glyph: &Glyph) {
span.text.push(glyph.codepoint);
}
- Appends each glyph's codepoint to the span's text field
- Handles single-codepoint glyphs directly
- Multi-codepoint glyphs (ligatures) are already expanded by Phase 2 into separate Glyph structs, so per-glyph append works correctly
2. Word Boundary Handling (lines 399-407)
When is_word_boundary == true on a glyph:
- Appends " " to the PREVIOUS span's text (option a from Phase 4.1 plan)
- Finalizes the current span
- Starts a new span with the boundary glyph (which is skipped itself)
- If no previous span exists (boundary at start of page), no space is injected
3. RTL Handling
- Spans containing RTL characters (Arabic, Hebrew) are emitted in VISUAL ORDER as they appear in the content stream
- Phase 4.2 line formation applies bidi reordering for output
- Span-internal text is left untouched
Acceptance Criteria Status
| Criterion | Status | Notes |
|---|---|---|
| 5 glyphs "Hello" -> span.text == "Hello" | PASS | test_assemble_text_five_glyphs_hello (line 1184) |
| 5 glyphs "Hello" + boundary + 5 glyphs "World" -> span1.text == "Hello ", span2.text == "World" | PASS | test_assemble_text_hello_world_with_boundary (line 1208) |
| Ligature glyph emitting (f, i) as 2 glyphs -> span.text == "fi" | PASS | test_assemble_text_ligature_fi_as_two_glyphs (line 1246) |
| RTL Arabic span: text in source byte order | PASS | test_assemble_text_rtl_arabic_preserved_in_source_order (line 1267) |
| Boundary at start of page: no space injection | PASS | test_assemble_text_boundary_at_start_of_page_no_space_injection (line 1294) |
