+# bf-xqib3: Remove Obsolete Generator Drafts and Compiled Artifacts
+
+## Summary
+
+Successfully removed all obsolete generator scripts and compiled artifacts from `tests/fixtures/` as identified in bead bf-1iefu categorization.
+
+## Changes Made
+
+### DELETE-category generators removed (5 files):
+
+1. **`tests/fixtures/scanned/generate_scanned_fixtures.rs`** (1,249 lines deleted)
+   - Reason: Rust stub, Python version is preferred and actively maintained
+   - Replacement: `scanned/generate_scanned_fixtures.py`
+
+2. **`tests/fixtures/security/generate_sensitive_fixture.py`** (348 lines deleted)
+   - Reason: Duplicate, Rust version preferred for security fixtures
+   - Replacement: `security/generate_sensitive_fixture.rs`
+
+3. **`tests/fixtures/encoding/generate_unmapped_glyphs.rs`** (156 lines deleted)
+   - Reason: Superseded by more comprehensive Python version
+   - Replacement: `encoding/generate_unmapped_glyphs.py`
+
+4. **`tests/fixtures/malformed/gen-bomb-10k-2g.sh`** (42 lines deleted)
+   - Reason: Superseded by more flexible Python version
+   - Replacement: `malformed/gen_bomb.py`
+
+5. **`tests/fixtures/forms/generate_form_fixtures.d`** (Makefile dependency file)
+   - Reason: Orphaned dependency file with no corresponding Makefile
+   - Status: Obsolete build artifact
+
+### Verification Results:
+
+✅ **No compiled object files found**: Searched for `.o`, `.so`, `.a`, `.dylib`, `.dll` files - none present
+
+✅ **No executable binaries found**: All executable files are legitimate shell scripts (`.sh`) and Python scripts (`.py`) with execute permissions
+
+✅ **Test data files preserved**: `.bin` files in fixtures root are LZW compression test fixtures, not compiled artifacts
+
+## Acceptance Criteria Status:
+
+- ✅ All DELETE-category generators removed with `git rm`
+- ✅ All .d files (dependency files from rustc) removed
+- ✅ No executable binaries remaining in tests/fixtures/
+- ✅ Changes committed: `chore(bf-xqib3): remove obsolete generators and compiled artifacts from tests/fixtures/`
