# MANTRA
**A deterministic, auditable programming language for ledger operations, cryptographic sealing, and verified integer computation.**
Zero external dependencies. Pure Python. Auditable SHA-256. MUMPS gateway.
SnapKitty West / SNAPKITTYWEST — *Evidence or Silence — 2026*
---
## What It Is
MANTRA is a purpose-built language for sovereign ledger operations. Every computation is deterministic and traceable. Every output can be cryptographically sealed. No external dependencies — the SHA-256 implementation is pure Python and auditable line by line.
```
# Constants and variables
const GENESIS = "0000000000000000000000000000000000000000000000000000000000000000"
let amount = 450000
# Annotated deterministic function
@deterministic
define seal(tx)
let h = sha256(tx)
Result::ok(h)
end
# Run
python mantra.py run examples/ledger.m
python mantra.py hash "hello world"
```
