Fifty-second bound growth on complete four-minute inputs

The format/API controls passed all six cases. This separately frozen diagnostic uses the current direct-source bound on the three original broad four-minute generated histories, under fixed-zero and profiled removal. Keep all 48,000 packets and the full original normalized parameter box [-1,1] in all 27 columns. Do not use the narrower sensitivity inputs or select an orientation sector.

Query the original 10,000-packet endpoint, nominally 50 seconds, preserving its literal sequential timestamp. Rebuild source references from each complete history. Use the qualified physical-domain directional acceleration proof, without importing short-history training constraints. Preserve the original fixed-clock limitation explicitly.

Checks and interpretation

For each case compare the native center and three fixed parameter probes with the mathematical bound. Retain the qualified 1 micrometre center-agreement and 10 micrometre probe allowances and all 51 expression columns. Use the original recording's frozen coordinate-to-metre scale for both sides of each check. Record exact probe inputs, source bindings, compiled-source hashes and actual prefix counts separately from reservations.

Report unshared approximation radii and conservative full physical-domain radii, including the shared terms. They are different quantities. Where the old profiled/broad study has the identical checkpoint, show its full-domain radius as historical context; leave missing baselines unavailable. Do not compare a new shared-term remainder alone with an old total-error range.

Numerical containment and runtime success do not establish useful aircraft prediction intervals. This screen has no training observations, no four-minute prediction and no uncertain-clock qualification. It cannot complete V01 or authorize withheld aircraft fits.

Finite allowance and estimated cost

Use the measured cost and bound growth to prepare the next complete-duration study or diagnose an inadequate bound. Do not spend a completed allowance or reinterpret a wide range as a passing uncertainty result.
