Three findings from the Codex 0.16.0 review, all conceded:

Fixed

  • Fenced errors keep MCP error semantics: the #45 error fence returned the structured envelope without isError: true, so generic MCP clients could classify a failed execution as success. Now returns isError: true with the same fenced envelope.
  • brand_context instructions point at real paths: next_steps and the tool description referenced data.context / data.output_contract; buildResponse spreads data at the top level. Corrected, with client-level path assertions.
  • A/B receipt-arm documentation corrected: clean/dirty tree stamps do NOT distinguish experiment arms (receipts accumulate as untracked files). RESULTS.md prose corrected, scores unchanged; receipts now stamp experiment_arm (EVAL_ARM env) + a dirty-diff hash.

1,004 tests.
