docs(bf-16far): document cleanup already completed by prior beads

The tests/fixtures/ directory cleanup was completed on 2026-07-05 by beads:
- bf-1iefu: categorize generator scripts
- bf-xqib3: remove obsolete generators and compiled artifacts
- bf-2yhak: relocate general-purpose tools

Verification confirms:
- No compiled binaries (.o, .so, .a, .dylib, .dll, .exe)
- No generator drafts (v2-v9 iterations, old, backup files)
- 1,530 legitimate fixture files only
- Clean git status

Closes bf-16far.

+# bf-16far: Remove generator drafts and compiled binaries from tests/fixtures/
+
+**Date:** 2026-07-08
+**Status:** ✅ **ALREADY COMPLETE** (Work done by prior beads)
+**Dependency:** bf-5bc3a (audit completed)
+
+## Finding
+
+The tests/fixtures/ directory has already been cleaned of all generator drafts and compiled binaries by beads completed on 2026-07-05:
+- **bf-1iefu**: Categorized all generator scripts into KEEP/DELETE/RELOCATE
+- **bf-xqib3**: Removed 5 obsolete generators and compiled artifacts
+- **bf-2yhak**: Relocated general-purpose tools to `tools/`
+
+## Verification
+
+### Compiled Binaries
+```bash
+find tests/fixtures/ -type f \( -name "*.o" -o -name "*.so" -o -name "*.a" -o -name "*.dylib" -o -name "*.dll" -o -name "*.exe" \)
+# Result: No files found (✅)
+```
+
+### Generator Drafts (v2-v9 iterations)
+```bash
+find tests/fixtures/ -type f -name "*v[2-9]*" -o -name "*draft*" -o -name "*old*" -o -name "*backup*"
+# Result: No files found (✅)
+```
+
+### Git Status
+```bash
+git status tests/fixtures/
+# Result: "nothing to commit, working tree clean" (✅)
+```
+
+## Removed by bf-xqib3 (2026-07-05)
+
+The following obsolete generator scripts were already removed:
+- `scanned/generate_scanned_fixtures.rs` (Rust stub, superseded by Python version)
+- `security/generate_sensitive_fixture.py` (duplicate, use Rust version)
+- `encoding/generate_unmapped_glyphs.rs` (superseded by Python version)
+- `malformed/gen-bomb-10k-2g.sh` (superseded by Python version)
+- `forms/generate_form_fixtures.d` (orphaned Makefile dependency)
+
+## Current State
+
+The tests/fixtures/ directory now contains:
+- **1,530 tracked files** (all legitimate fixture data)
+- **12 active generator scripts** (all maintained and in use)
+- **164 metadata/documentation files** (README.md, PROVENANCE.md, expected.json, etc.)
+- **0 compiled binaries**
+- **0 obsolete generator drafts**
+
+**Source:** `notes/bf-5bc3a-audit.md` (complete fixtures audit dated 2026-07-08)
+
+## Acceptance Criteria
+
+- ✅ All generator drafts removed (done by bf-xqib3)
+- ✅ All compiled binaries removed (done by bf-xqib3)
+- ✅ git status shows only legitimate fixture data remaining
+- ✅ Single commit documenting the state (this note)
+
+## Conclusion
+
+**No further action required.** The tests/fixtures/ directory is clean and well-organized. This bead's objectives were achieved by prior work on 2026-07-05.
