Coarse-group recognition contract
Family 255: Quasi-isometric recognition of virtually polycyclic groups. First application triage, 9 October 2026 Australia/Brisbane.
Problem and potential new use
Track virtual polycyclicity under quasi-isometry and the companion solvable-Lie-lattice recognition statement.
Applicability and commercial boundary
A quasi-isometry assumption is not obtained merely from sampled metric similarity; the resulting Lie group can differ.
Initial business decision
Research reference or conditional symbolic/verification engineering. No recurring buyer need, practical implementation or profitability has been demonstrated. Defer a standalone commercial product until a constructive example and a measurable workflow improvement exist. These records also identify unsupported inferences that an evidence platform could flag.
Next verification action
Inspect effective recognition and explicit quasi-isometry input requirements.
Evidence scope
The repository catalog statement was individually read. Main-paper construction, effectiveness and selected formal-scope comparison remain queued for this record. No independent Lean verification was run. Source revision fd4aeeb2ee4fc729c18d98444fed42fd0529eeeb. See source metadata.
