Intry Verified receipt
Is the Intry Box Fill Calculator accurate and NEC compliant?
The provenance receipt for the Intry Box Fill Calculator: the exact authority its numbers derive from, the edition they are keyed to, who has final say, and how a deploy gate holds every figure to its cited source.
Short answer: Every calculated figure is re-derived from its locked source before any deploy, backed by 4889 automated checks that also guard where each number comes from. A number that drifts from the cited NEC section blocks the ship. This is our own deterministic gate, not a third-party audit. The per-tool receipt is public at https://www.intrysys.com/verified.
The receipt
- Calculated from
- the cited NEC section (NEC 2023). Reused verbatim from the locked engine, never re-written for this page.
- Checked
- Before any deploy, a deterministic test suite re-derives every calculated figure from its locked source and checks it against the actual published source it cites, so the number is right, not just consistent with itself. As of the current build that suite holds 4889 checks, and it gates this page too. This is our own deterministic gate, not a third-party audit.
- Runnable
- Exposed at the Intry MCP endpoint. An AI assistant can run this calculator, and a deploy-gating check asserts its computed result is identical to the locked engine the website uses.
- Final say
- Your AHJ and local amendments have final say. Confirm before rough-in.
