Bulk comment cleanup deleted 51 load-bearing proof annotations across 12 workers

A software project undertaking a bulk comment-removal effort deployed twelve parallel workers to strip over 1,900 comment blocks from source files and relocate them to an evidence ledger. All twelve workers passed a control check confirming every removed line was a comment, but the check did not verify whether any comments were actively consumed by other tools. Fifty-one removed lines were docstrings in proof files that a parser relied on to map theorems to stated requirements; without them, the requirement-coverage system reported failures even though the underlying proofs still compiled. The issue was caught one commit after the worker landed, when the docstring reader flagged orphaned requirement rows. Both affected files were fully restored, and the project now maintains a declared list of files whose comments are parsed by tools, excluding them from bulk removal by configuration rather than relying on individual worker caution.
