//! The version-stamp convention (ADR-017 §4.2, adopted here as the
//! suite's row discipline — ADR-022).
//!
//! Each property row is version-stamped with the contract change that
//! added it — ADR-017 §4.2's requirement that makes the suite
//! auditable against the core crate's changelog (whose entries cite
//! their ADRs by §2's no-silent-change rule).
//!
//! # The convention
//!
//! A row's stamp is a doc-comment list item beginning
//! **`Contract stamp:`** on the row's doc text, citing the ADR § (or
//! the backlog row) that pinned the behavior being tested:
//!
//! ```text
//! /// <one-line statement of the property>
//! ///
//! /// Contract stamp: ADR-008 §4 (reserved namespace, entry-point
//! /// validation); ADR-021 §3 (the schedule queue argument).
//! pub async fn row_name(factory: &dyn StoreFactory) { ... }
//! ```
//!
//! Rules:
//!
//! - The stamp cites the ADR § that pins the property — never a bare
//!   "v1" or a date. A row may carry multiple stamps when it tests
//!   several changes' behavior together (the exemplar row does).
//! - A row added to pin a new contract addition is stamped with that
//!   addition's ADR; a row whose property predates the suite is
//!   stamped with the ADR that pinned the behavior it tests.
//! - When a later contract change *amends* a row's property, the
//!   row's stamp list gains the amending ADR (rows accumulate stamps;
//!   the ADRs' own texts record the row history).
//! - `Contract stamp:` is greppable: `grep -r "Contract stamp:"
//!   alkstore-contract-suite/` lists the suite's stamp inventory.
//!
//! Version 0 of the suite: this module *is* the convention's
//! normative statement; every later row cites its stamp against it.
