Pre-release. This site describes standard version 0.7.0-dev, which is in development and may change before version 1.0.0.
A short record of a site’s land cover and intactness, observed by a fieldworker or supervisor on site, or by an office analyst at the desk or remotely, for a site whose registration left them blank or whose cover has changed (#130). Its state counts with the registration’s and every site record’s: the latest observation wins, and it lets a blank site be assessed.

Rules
- A record names an observer enrolled in the role it claims, to the record’s site or to a project design the site is registered to: the role comes from the enrolment, never from the form (ADR-0004, ADR-0007).
- A site record in a project ledger is about a registered site: its site has a site registration record, so an export for a case no registration created fails whatever pipeline produced it.
- A record moves to another site only by a supervisor’s or an office analyst’s correction in one role, observed at one zoned time, to a registered site current when it moves, and with each thing its restatement group introduced before it withdrawn or replaced by the move or a correction before it (ADR-0027).
- A restatement is a record of the same type as the record it restates (ADR-0018).
- A restatement is about the same site as the record it restates, or follows in its restatement group, unless a supervisor’s or an office analyst’s correction moves it (ADR-0018, ADR-0027).
- A restatement is observed after the record it restates: it is the later observation that governs (ADR-0018).
- A restatement says why the fact is restated, in a sentence or more (ADR-0018).
- A site registration never moves: its correction registers the site its original registered, and a site registered in error is replaced (ADR-0027).
- An office analyst never observes on site: the basis is at the desk or remote (#130).
