Records and domains

A record is only as good as what an independent verifier can recompute from it.

**Table 3.** Properties every sealed record carries.
Property	Rule
Deterministic	The same inputs produce the same outputs; runs replay bit for bit on the same platform.
Sealed	Configuration, outputs and evidence are bound by SHA-256 over canonical bytes; later edits are detectable.
Independently verified	Verifiers recompute hashes, counts and verdicts instead of trusting what a record says about itself.
Units on every number	Each value carries its declared unit and its SI equivalent (temperatures in kelvin). Unresolved units are refused.
Registered models only	Only registered, governed models can seal results; anything else is refused.
Failures preserved	Raw evidence is immutable; a new attempt is a new record.

**Table 4.** Accuracy is earned per domain, one stage at a time.
Stage	What it establishes
Laboratory benchmark	Core physics and the measurement chain on the simplest apparatus.
Coupled benchmark	Interaction of two domains (air and a solid panel) under control.
Published datasets	Agreement with independent, peer-reviewed measurements.
Scale models and sites	Real geometry, ground and weather.
Replication	The same frozen protocols on other people's instruments.

A prediction outside the validated domain remains a hypothesis, never a result.
