mmux_vite's V47pk route test caught a V21pf leak on the grid path: SumoSession.grid inverse-mapped the response key but not the engine's COMPANION series — the predicted-std column hangs off the MAPPED response name (y1_std), passed the inverse-mapping unknown-key passthrough, and surfaced as a mapped-name key in GridResult.data. Consumers look up gridData[qoi + "_std"]; the leak camelCases on the wire and the FE lookup silently misses (empty 2D/3D plot at HTTP 200 — the exact B29dr bug class mmux hardened with V47pk).

  • grid loop renames {mapped_response}_* companions to {response}_* (suffix kept) beside the plain response rename
  • regression test: fixture QoI renamed to max_abs_stress; asserts no y1* key ∧ std companions ⊆ {max_abs_stress_std}
  • SPEC §B B21ru; 391 passed full suite (real Dakota)
  • version 0.1.0a9 → 0.1.0a10 (mmux_vite Phase C pin)

SumoSession.grid inverse-mapped the response key but not its companion:
the engine hangs the predicted-std column off the MAPPED response name
(y1_std), which passed the inverse mapping's unknown-key passthrough --
so GridResult.data carried y1_std for an underscored QoI. Consumers
look gridData[qoi + "_std"] up; the leak camelCases on the wire and the
lookup silently misses (caught by mmux_vite's V47pk route test).

- grid loop renames {mapped_response}_* companions to {response}_*
  (suffix kept) beside the plain response rename (V21pf)
- regression test: QoI renamed to max_abs_stress asserts no y1* leak
  and std companions subset of {max_abs_stress_std}
- SPEC B21ru; version 0.1.0a9 -> 0.1.0a10
