jedarden 50d443d86e docs(bf-1ubcb): verify fuzz harness build configuration

- Confirm cargo-fuzz 0.13.1 installed
- Verify content fuzz target at fuzz/fuzz_targets/content.rs
- Build succeeds: cargo fuzz build produces all 7 fuzz target binaries
- No compilation errors or dependency issues
- Document verification in notes/bf-1ubcb.md

Fuzz Harness Build Verification (bf-1ubcb)

Date: 2026-07-06

Summary

Verified that the content fuzz harness is properly configured and builds successfully.

Verification Results

✅ PASS: cargo-fuzz installation

cargo-fuzz 0.13.1

The cargo-fuzz tool is properly installed.

✅ PASS: Content fuzz target exists

The fuzz target is located at fuzz/fuzz_targets/content.rs (not content_fuzzing_targets.rs as mentioned in the task description - this appears to be a naming inconsistency).

Target structure:

Tests INV-8 (no panic at public boundary) for content stream interpreter
Tests both ProcessingMode::Normal and ProcessingMode::PositionHint
Uses proper fuzzer setup with libfuzzer_sys::fuzz_target!
Handles all input without panic (safety invariant)

✅ PASS: Fuzz harness builds successfully

cargo fuzz build

Completed without errors. Built binaries:

content (59MB) - the main content fuzz target
Additional targets: cmap_parser, lexer, object_parser, profile_yaml, stream_decoder, xref

All 7 fuzz targets compiled successfully with no compilation errors.

Acceptance Criteria Status

✅ cargo fuzz --version succeeds
✅ Content fuzz target file exists (at fuzz/fuzz_targets/content.rs)
✅ cargo fuzz build completes without compilation errors
✅ No unresolved dependencies or build failures

Notes

The task description referenced content_fuzzing_targets.rs but the actual file is content.rs. This appears to be a documentation discrepancy - the actual fuzz target is properly named and functional.

All fuzz harness infrastructure is working correctly and ready for fuzzing operations.
