taxonomy-drift-accumulates-silently-across-skill-prose
Over time, legacy synonym pairs accumulate across skill prose without triggering lint: confirm instead of verify, mismatch instead of drift, scanning instead of scan, api spec/definition/endpoint spec instead of API Contract, data shape/structure spec instead of Schema. 45 instances were found across 28 skills in this session. The fix is targeted sed-style replacement in prose while preserving fenced code blocks. Add BANNED_SYNONYMS to fusion-invariants-lint.py to prevent re-accumulation.
