Prove How Your Software Behaves

Independent, deterministic execution truth - not opinions, logs, or guesses.

"SATE proves what software actually does.
It does not explain, fix, or guess."
  • Language-agnostic
  • No test requirement
  • No runtime modification
  • Immutable evidence
  • Audit- and government-grade

SATE is intentionally strict. Not all systems qualify.

What SATE Is

  • An execution-truth certification system
  • A read-only observation layer
  • A trust boundary outside developer tooling
  • A forensic and audit-grade evidence generator

What SATE Is Not

  • Not a test framework
  • Not a CI replacement
  • Not a debugger
  • Not an AI agent
  • Not self-healing
  • Not opinionated

Why Devtools Are Not Proof

Devtools run inside the system they observe
Devtools interpret and overwrite history
Devtools are not independently verifiable
Devtools output is not admissible for audits or disputes
Devtools explain.
SATE proves.

How SATE Works

Pure observation (no execution required)
Optional runtime triggering (HTTP, CLI, messages)
Canonical event capture
Immutable run snapshots
Run-to-run comparison without interpretation

Who SATE Is For

  • CTOs accountable to boards and regulators
  • Government and public sector entities
  • Critical infrastructure operators
  • Vendors required to prove behavior
  • Auditors and certification bodies

Who SATE Is Not For

  • Teams looking for faster debugging
  • Teams expecting auto-fixes
  • Teams unwilling to expose nondeterminism
  • Early-stage hobby projects

“We Already Have Devtools”

SATE does not replace devtools.

SATE operates outside your toolchain.

SATE freezes evidence that devtools cannot.

SATE exists for accountability, not productivity.
