# LIFE Engineering Philosophy
|
|
|
|
> *"Reality is the source of truth. Everything else is a model."*
|
|
|
|
## Core Principles
|
|
|
|
### 1. Evidence Before Opinion
|
|
No decision is made without supporting evidence. No claim is accepted without verifiable data. The platform exists to make reality visible, not to confirm preconceptions.
|
|
|
|
### 2. Protect the Runtime
|
|
The Runtime is the foundation. It must remain stable, predictable, and backward-compatible. Domains come and go; the Runtime endures.
|
|
|
|
### 3. Everything is Observable
|
|
If it happens, it must be measurable. If it is measurable, it must be logged. If it is logged, it must be queryable. No invisible operations.
|
|
|
|
### 4. Everything is Explainable
|
|
Every decision, every risk score, every state transition must be explainable. Black boxes are not acceptable in production.
|
|
|
|
### 5. Reality is the Source of Truth
|
|
The physical world is the ultimate authority. All data, models, and predictions are approximations. The platform exists to reduce the gap between model and reality.
|
|
|
|
### 6. AI Assists. Evidence Decides.
|
|
AI models may suggest, predict, or classify. They do not decide. The Runtime evaluates evidence and makes deterministic decisions based on rules.
|
|
|
|
### 7. Every Decision is Reproducible
|
|
Given the same inputs, the system must produce the same outputs. Non-determinism is a bug.
|
|
|
|
### 8. Every Object Has a History
|
|
Nothing exists without context. Every object carries its full lifecycle: creation, changes, observations, risks, events, and resolutions.
|
|
|
|
### 9. Every Observation Has Provenance
|
|
An observation without source, timestamp, and method is not evidence. It is noise.
|
|
|
|
### 10. Runtime First. Domains Second.
|
|
The Runtime serves all domains equally. No domain may introduce special cases into the core. Domains extend; they do not modify.
|
|
|
|
## Engineering Values
|
|
|
|
- **Stability over speed.** A slow correct answer is better than a fast wrong one.
|
|
- **Clarity over cleverness.** Code is read more often than it is written.
|
|
- **Observability over optimization.** You cannot optimize what you cannot see.
|
|
- **Simplicity over features.** Fewer moving parts means fewer failure modes.
|
|
- **Explicit over implicit.** Magic is acceptable only when fully documented.
|
|
|
|
## Decision Framework
|
|
|
|
When in doubt, ask:
|
|
|
|
1. Does this protect the Runtime?
|
|
2. Does this improve observability?
|
|
3. Does this make the system more explainable?
|
|
4. Does this respect the boundary between Runtime and domains?
|
|
5. Would this decision still make sense if we had 100 domains?
|
|
|
|
If the answer to any question is "no", reconsider.
|
|
|
|
## Invariants
|
|
|
|
These rules never change:
|
|
|
|
- No observation without timestamp.
|
|
- No observation without source.
|
|
- No state transition without logging.
|
|
- No API change without versioning.
|
|
- No domain logic in the Runtime.
|
|
- No Runtime dependency on any domain.
|
|
- No manual intervention without audit trail.
|
|
- No data deletion without justification.
|
|
|
