Subject: [PATCH] docs(bf-644ci): verify no-mapping.pdf unmapped glyph
 documentation

Verified that existing documentation at tests/fixtures/no-mapping.md
comprehensively catalogs the 3 unmapped glyphs (g001, g002, g003)
with CID numbers and explanations for why they're unmapped.

All acceptance criteria met - documentation already complete from
previous bead bf-68f9i.

Closes bf-644ci

+# bf-644ci: Verify no-mapping.pdf unmapped glyph documentation
+
+## Task
+Identify and catalog unmapped glyphs in no-mapping.pdf fixture
+
+## Verification Summary
+
+Verified that existing documentation at `tests/fixtures/no-mapping.md` is comprehensive and accurate.
+
+### Unmapped Glyphs Confirmed
+
+The fixture contains exactly 3 unmapped glyphs:
+
+1. **`/g001` (CID 0)**
+   - Custom glyph name not in Adobe Glyph List (AGL)
+   - Font `/CustomNoMap` is not a standard Adobe font
+   - No ToUnicode CMap present
+   - Should recover as "A" via Level 4 glyph shape recognition
+
+2. **`/g002` (CID 1)**
+   - Custom glyph name not in Adobe Glyph List (AGL)
+   - Font `/CustomNoMap` is not a standard Adobe font
+   - No ToUnicode CMap present
+   - Should recover as "B" via Level 4 glyph shape recognition
+
+3. **`/g003` (CID 2)**
+   - Custom glyph name not in Adobe Glyph List (AGL)
+   - Font `/CustomNoMap` is not a standard Adobe font
+   - No ToUnicode CMap present
+   - Should recover as "C" via Level 4 glyph shape recognition
+
+### Verification Methods
+
+1. **PDF Structure Verification:**
+   - `pdfinfo`: Confirms PDF is valid (1 page, 660 bytes, PDF 1.4)
+   - `pdffonts`: Shows CustomNoMap Type 1 font with Custom encoding, no Unicode mapping
+   - Direct PDF inspection: Confirmed encoding array `/Differences [0 /g001 /g002 /g003]`
+   - Content stream verification: Confirmed glyph sequence `<g001><g002><g003> Tj`
+
+2. **Documentation Review:**
+   - Existing documentation at `tests/fixtures/no-mapping.md` is comprehensive
+   - Includes fixture overview, unmapped glyph details, font configuration, content stream
+   - Explains recovery strategy and why fixture exists
+   - All acceptance criteria met
+
+### Acceptance Criteria Status
+
+- ✅ Documentation file exists at tests/fixtures/no-mapping.md
+- ✅ Lists 3 specific unmapped glyphs by CID/glyph name
+- ✅ Explains why each glyph is unmapped
+
+### Conclusion
+
+The documentation was already created in a previous bead (bf-68f9i) and is accurate and complete. No additional work required.
