Three circle-packing candidate records sent for independent verification

The result: Aletheia produced fixed coordinate files for 600, 700, and 800 equal circles in a square. A check that does not round the coordinates found that every circle stays inside the square and no two circles overlap. Each file supports a radius just above the value printed in the public Packomania catalog. These are candidate records, submitted to the catalog maintainer for verification. They are not accepted records and do not prove the best possible packings.
What it means: For each of three crowded square puzzles, the new file fits all the circles without overlap and is a little better than the public catalog entry. The catalog maintainer now has the files to check.
What it is NOT: Not three accepted records, because the catalog maintainer has not confirmed them. Not proof of the best possible packings, because one working layout cannot rule out a better one. Not universal proof of novelty, because private or unindexed stronger files may exist.
Next test that could settle it: The catalog maintainer reruns the three coordinate files and compares them with the current catalog and any earlier private files. Any failed wall or pair check, or any earlier equal or stronger file, removes that candidate.
Open question: Will the Packomania maintainer reproduce and accept the three packing candidates?
Receipts (exact limits and evidence records)
Claim ceiling (the strongest sentence this evidence supports): Three fixed coordinate files fit 600, 700, and 800 equal circles in a square at checked radii above the values printed in the public Packomania catalog. They are candidate records, submitted to the catalog maintainer for verification. They are not accepted records, do not prove the best possible packings, and do not rule out earlier private or unindexed results.
Novelty: Three fixed coordinate files pass full wall and pair checks at slightly larger radii and were sent to the catalog maintainer.
