# Investigation: Pre-existing test failures and compile errors

## Task Description

The bead description mentioned 10+ compilation errors in `--lib --tests` mode and 13 runtime test failures.

## Investigation Results

### Compile Errors
**Status: NOT FOUND** - All compile errors mentioned in the bead description were already fixed.

- `cargo build --manifest-path Cargo.toml` - **SUCCEEDS** ✓
- `cargo test --lib --no-run` - **SUCCEEDS** ✓
- `cargo clippy --all-targets -- -D warnings` - **PASSES** ✓

### Test Results
**Status: ALL PASSING** - No test failures found.

Verified test modules:
- `strand::` - 257 passed, 0 failed
- `strand::mend::` - 90 passed, 0 failed
- `telemetry::` - 105 passed, 0 failed
- `transcript::` - 10 passed, 0 failed
- `drift::` - 9 passed, 0 failed
- `decision::` - 8 passed, 0 failed

### Root Cause

The issues mentioned in the bead description were likely fixed in one of these recent commits:
- `d7dc332 feat(needle-i5xk): emit telemetry events for transcript, drift, and ADR features`
- `c5090e0 feat(needle-mbio): add reflect config fields for transcript, drift, and ADR`

These commits added the `EventKind` variants that were mentioned as missing in the compile errors (DriftDetectionStarted/Completed/Skipped, DecisionDetectionStarted/Completed/Skipped, ReflectDriftPromoted, ReflectDecisionExtracted, ReflectAdrCreated).

## Conclusion

No fixes were required - all issues mentioned in the bead description were already resolved in the current codebase.
