Observable
What the record can directly show
Identity, time basis, channel, unit, cadence, and missingness are preserved before interpretation.
Company method
Method before interpretation.
The same grammar is used wherever LFR has a qualified evidence base: preserve what was actually observed, state what was derived, mark what was assumed, and refuse what the trace cannot establish.
Boundary. This page describes the discipline. Domain claims still require their own contracts, manifests, trace packages, and verdict files.
Claim ladder
Six states we keep separate
Derived
What a frozen transformation computes
Derived figures carry their source, method, and recompute path.
Assumed
What enters by contract
Assumptions are named so they do not masquerade as observations.
Unknown
What remains unresolved
Unknown is not a failure state. An unmarked unknown is.
Recomputable
What a third party can rerun
A result has no public authority unless its path can be checked within its boundary.
Not established
What the evidence cannot support
Unsupported claims are refused instead of softened into marketing language.
Instantiated fields
The grammar is shared; evidence is local.
GB Grid and Battery/BESS pages are field-specific implementations of this method. They do not inherit authority from this page; they earn it from their own records.
