Frozen scope: recover missing long-history reports

The preceding six-case software study completed its calculations but rejected exactly matching reports because Python tuples become lists in JSON. Its failure records and all charges remain unchanged.

This separate study can recover only a later cached report that was not saved after that false comparison. Admission requires a completed, hash-verified parent study, exact equality of every available report, complete original and point-oracle records, and compliance with the original time and memory limits. A genuine numerical mismatch or incomplete calculation is not eligible for this repair.

Limit Scope
Histories At most four audited globe histories; the two disc histories reuse their complete saved reports
Input The same 96,000 packets, parameters, conditioning proof and two queries at 290 and 438 seconds
New work per history One cached two-query batch, at most 192,000 packet steps
New point-oracle or original-cold calculations Zero
New optimizer starts or original aircraft reads Zero
Maximum total new cached batches Four
Maximum charged bound steps 6,912,000
Numerical allocation At most four workers, one thread each; frozen before launch
Per-batch time limit 14,400 seconds
Whole-study time limit 21,600 seconds
Peak memory At most 1,536 MiB per worker
Retries or allowance expansion None

The saved audit fixes the actual task set before preparation. No run can start until the parent closes and the numerical regression passes. The passed regression must still match its recorded code hashes. The repair reuses the common native batch library and accepts no cold-solver or point-oracle callable.

Every returned report and its work accounting are saved before comparison. Acceptance requires exact serialized report equality, agreement of all 51 coefficient columns, and the unchanged 0.00001-metre software arithmetic allowance against the saved independent point checks. This allowance is not a sensor accuracy specification.

All six histories must have complete verified comparisons to qualify long-history reuse. Passing does not qualify whole-record uncertainty, observational coverage, an Earth-model detection or any new use of protected confirmation observations.
