1. Remove root-level shim files (errors.ts, logger.ts, registry.ts, types.ts, utils.ts, launcher.ts) — update all ~840 adapter imports to reference src/ directly 2. Consolidate interceptor: reuse shared DISGUISE_FN in tap interceptor instead of reimplementing 3. Unify error classification: single ClassifiedError type with icon/exitCode/hint lookup table, eliminating duplicated pattern matching between resolveExitCode and renderError 4. Simplify cascade probe: replace repetitive switch cases with PROBE_OPTIONS lookup map 12. Clean up synthesize.ts: remove deprecated snake_case field aliases (recommended_args, recommended_columns, recommendedColumnsLegacy) and unnecessary constant aliases Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
