   - **Done (2025-12-25 10:44)**: WHAT: captured refactor/test/typecheck audit in `REPORT-refactor-validation-test-audit.md:1` and stored full test output in `test-output.txt:1`; updated task status and follow-up tasks in `plan.md:538`. RESULT: found remaining `Record<string, unknown>` usage across agent files, 1 failing test + 1 skipped test before suite halted with MCP JSONRPC error, and 5 typecheck errors in `codex-mcp-agent.ts`. EVIDENCE: `rg -n "as \\{|as Record|Record<string, unknown>" packages/server/src/server/agent/`, `rg -n "\\?\\?" packages/server/src/server/agent/providers/codex-mcp-agent.ts`, `npm run test --workspace=@paseo/server 2>&1 | tee test-output.txt`, `grep -E "skip|Skip|SKIP|todo|TODO" test-output.txt`, `npm run typecheck --workspace=@paseo/server`.
