Blind validation of the frozen core

Research question

What computational or evidential boundary did blind validation of the frozen core establish?

Source record

• Generation position: 28 of 30
• Preserved source: mira_canonical/docs/FROZEN_CORE_BLIND_VALIDATION.md
• Original record: FROZEN_CORE_BLIND_VALIDATION.md

Observed result

OBSERVED

Held-out fixtures were run against a frozen core to reduce the chance that the executor encoded expected answers.

Interpretation

This record tightened a computational or evidential boundary before the current Living Runtime line began.

Failure and limitations

RESIDUAL

This is a historical record. Its implementation is archived and does not define current MIRA behavior. The observation is limited to the source fixture and should not be read as a general capability claim.

Next question

The curated lineage continues with Cross-domain validation.
