Inline base64 source maps had been checked into tracked src files. This strips those comments from the repository without changing runtime behavior or adding ongoing guardrails, per the requested one-time cleanup scope. Constraint: Keep this change limited to tracked source cleanup only Rejected: Add CI/source verification guard | user requested one-time cleanup only Confidence: high Scope-risk: narrow Reversibility: clean Directive: If these directives reappear, fix the producing transform instead of reintroducing repo-side cleanup code Tested: rg -n "sourceMappingURL" ., bun run smoke, bun run verify:privacy, bun run test:provider, npm run test:provider-recommendation Not-tested: bun run typecheck (repository has many pre-existing unrelated failures) Co-authored-by: anandh8x <test@example.com>
