## Admission result

All seventeen frozen gates pass. In addition to counts, independent oracle
agreement, renderer parity, split/prior leakage exclusions, unique names,
outcome custody, and access sealing, every one of the 52,096 rows is accepted by
the exact production `parse_projected_row` path. This directly closes the v1.1
redundant-event-name defect before GPU execution.

A second full generation from the same source, seed, and prior inputs is
byte-identical for all four artifacts. The post-receipt training draw is now
recorded above; no optimizer, output, or scored read exists. This authorizes
only the sole preregistered development pilot; it does not authorize
confirmation or establish reasoning.
