Deprecated Survivability
This page is retained for historical context only.
Current Status
Survivability is deprecated for primary use.
It is not the canonical score input, not the canonical deployability contract, and not the certified explanation path for the current product.
Why It Was Deprecated
- deterministic decay is cleaner and more explicit for persistence handling
- observed risk is more direct for downside interpretation
- survivability-led primary semantics mixed too many ideas into one branch
What To Use Instead
If survivability appears anywhere else in the product or public materials, it should be clearly marked as legacy, deprecated, or diagnostic-only.
