# Ocean6 v0.2 validation record — 2026-09-19

Scope: local literal-line-search reference only. Self-published engineering checks, not an independent security audit or network benchmark.

- 9 Python tests passed: boundaries, Unicode, ordering, tampering, duplicate keys and CLI receipt binding.
- 80 independent Python / JavaScript comparisons passed with fixed seed 6.
- Browser local execution, changed input, replay PASS and modified output FAIL were exercised in cloud Chrome.
- Release quickstart was run from an extracted ZIP: run, verify and compare all passed.
- Desktop and responsive iframe layouts were inspected. No physical mobile-device or Safari validation is claimed.

Reproduce:

```sh
python3 test_reference.py
# Optional, requires Node.js:
python3 test_cross_runtime.py
```

Test environment: Python 3.12.14, Node.js v24.19.0. Runtime compatibility beyond the tested environment is not certified.

Implementation SHA-256:

- reference_runtime.py: `3188b54c93976182704eef2fa4b96a4496f9aa81d965b2fd142ad550c62ea55c`

These checks do not authenticate an executor, demonstrate GPU or LLM execution, establish network capacity, prove payment or guarantee production security.
