Where the model came from
The page is a source ledger rather than a legal model. 48 entries are grouped under 9 reader questions, and each entry names its instrument and pinpoint while carrying one explicit basis: primary, secondary, historical or comparative.
Every reference on this shelf carries its jurisdiction and its date as fields rather than as prose, so a reader can see at a glance whose instrument it is and how old the edition described is. Where a record's own text does not state a date, the field says so instead of guessing one.
A walked example
Under How it ends, the registered-agency exit rule is cited separately for each jurisdiction. The English examples then sit below both jurisdiction blocks under Mechanism, not Gulf law, with their own verification lines. The page does not calculate an exit date from any of those periods.
What this does not model
It does not classify an arrangement, apply a notice period to a contractual effective date, resolve a source conflict or predict a committee or court decision. Model-contract material is omitted pending a source-by-source publication-licence check, and unread source documents contribute no entry.
