- BioLight is a transparent entropy engine that passively collects high-quality entropy from raw inputs without hashing, whitening, or compression.
- Operates indefinitely in the background, building a 'battery' of entropy blocks that grow stronger over time.
- Uses passive-only entropy collection from system events and natural variations, avoiding active probing or synthetic noise.
- Stores entropy in raw form without mandatory post-processing like SHA or XOR, allowing direct export and analysis.
- Implements selective refinement, preserving only samples that exceed a predefined entropy threshold for high-quality output.
- Transparent inputs include screen state, timing jitter, volatile memory, system noise, and RAM feedback.
- Designed for indefinite runtime, silently capturing rich input activity while rejecting weak input.
- Achieves ≥ 7.9999 bits per byte of raw entropy, with symmetric and statistically uniform bitstreams.
- Each entropy block includes timestamp, entropy score, input source classification, and raw 32-byte payload.
- Suitable for cryptographic entropy injection, identity seed generation, scientific simulation, and entropy benchmarking.
- Released under the Ladaxia_Public_License, permitting educational, research, and personal use but restricting commercial use without agreement.
