enforce parity visibility in high rigor workflow

 | ERR-060 | Legacy Sphuta functions combined approximate Gulika with interpretive signals, while the exact formula could not be inspected in the production question context. | mitigated 2026-07-14 | `prashna_sphuta.py` exposes formula-only Trisphuta/Catusphuta/Pancasphuta from the partial Gulika evidence. It is supporting-only; Kunda, life-sensitive Sphutas and Prashna verdicts remain blocked pending external numeric parity. |
 | ERR-061 | Full-reading passed longitude-only data to the Tajika layer, permanently blocking its speed-dependent seven-planet interaction evidence. | mitigated 2026-07-14 | Pass actual Swiss longitude/speed pairs. The output may expose only partial Ithasala/Easarapha candidates; named chains and event verdicts stay blocked pending golden cases. |
 | ERR-062 | A release gate could validate a parity manifest's shape without requiring all external engines to actually match, allowing “contract valid” to be mistaken for “oracle verified.” | mitigated 2026-07-14 | `three_engine_parity_replay_validator.py --require-pass` fails unless parity status is pass; `run_quality_gate.py --require-external-parity` exposes this as an explicit high-standard release requirement. |
+| ERR-063 | High-rigor API output could omit the three-engine parity state, especially on plan-only responses, allowing downstream UI or MCP callers to overstate verification. | mitigated 2026-07-14 | Every high-rigor execution and plan response carries `high_rigor_external_parity`; `require_external_parity=true` sets `success=false` unless parity is pass. |
