/-! # Generalized Evolutionary Signal Transform: Multi-Species Domain-Bound Model
This module generalizes the domain-bound signal transform to encompass multiple
long-term evolution experiments across different organisms, environments, and conditions.
**Attack on LTEE-Only Model**:
The original model was overly specific to E. coli LTEE. Broader literature reveals:
1. Generation rates vary widely (5.9-6.67/day for bacteria, different for yeast/viruses)
2. Population sizes vary (12-205 populations)
3. Environmental conditions vary (glucose-limited, CF sputum, urea, antibiotics)
4. Selection pressures vary (nutrient limitation, environmental stress, fecundity/longevity trade-offs)
5. Ploidy states matter (haploid vs diploid)
6. Mutation rates vary (mutator phenotypes vs baseline vs viral rates)
7. Coexistence dynamics differ (long-term vs absent)
8. Genetic targets vary (DNA topology vs ADE pathway vs core proteins)
**Expanded Dataset**:
- LTEE (E. coli): 60,000+ generations, 12 populations, glucose-limited DM25
- LTEE replay: Cit+ extinction, 10,000+ generations coexistence, 20-fold replication
- Pseudomonas: 48 populations, ~50 generations, ~5.9 generations/day, CF sputum + antibiotics
- E. coli DNA topology: 20,000 generations, topA/fis mutations, DNA supercoiling
- Yeast: 205 populations, 10,000 generations, 3 environments, haploid/diploid
- Bacteriophage T7: 11 rounds, urea survival, fecundity/longevity trade-off
**Generalized Model**:
- Multiple organism types (bacteria, yeast, viruses)
- Variable generation rates
- Multiple environmental conditions
- Different selection pressures
- Ploidy state handling
- Mutation rate variation
- Coexistence dynamics
Per AGENTS.md §2: PascalCase types, camelCase functions.

where the transform handles:
1. Multiple organism types (bacteria, yeast, viruses)
2. Variable generation rates
3. Multiple environmental conditions
4. Different selection pressures
5. Ploidy state effects
6. Mutation rate variation
