CK: Remove 41 commented-out dead code blocks (~200 lines) (#6302) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Depends on #6300 ## Summary Remove 41 commented-out code blocks across 33 files in Composable Kernel, totaling ~200 lines. Identified using an automated dead code scanning skill (`ck-dead-code`) with a calibrated two-stage pipeline: 1. **Pre-filter**: Keyword-based scan found 1,338 `//`-commented blocks. Calibrated heuristics (trained on 50-sample expert classification) reduced to 89 high-confidence candidates — 93% noise reduction. 2. **Expert triage**: LLM expert classified each block in context as CODE_REMOVE, CODE_KEEP, or NOT_CODE. | Classification | Count | |---------------|-------| | Removed (this PR) | 41 | | Kept (debug helpers, alt configs, reference impls) | 32 | | Not code (false positives) | 16 | Removed blocks include: superseded implementations, old test data, abandoned stubs, unreachable code, and buggy dead code.
