• From format: ess/28 a view reads the row a reference of its source names, one hop, as that
  row is when the view is read (docs/design/generic-language-features.md § G2, navigation,
  grid R's view-field and view-filter rows): a field declares field: {related: {via: <reference>, field: <field | state>}}, typed Optional since it is absent where the reference
  is absent or names no row, and a filter reads <reference>.<field>, unknown there, so the row
  is not shown. The interpreter reads the referenced row at query time; synthesis files one
  <view>/reference/<field> scenario per view and reference (suite ess-conformance/54, or /55
  with coverage) reading the view before and after the referenced row changes, beside a decoy row
  and an absent reference; the Rust, Go and TypeScript runners give one verdict on it; generated
  Rust and Go keep such a query an obligation, named; ess verify diff reports a field's source
  moving as field-source-changed (ess-diff/21). An aggregate, paged or absent: view and an
  order key read through a reference are refused by name; below ess/28 every such read is
  refused naming ess/28, and a model without one keeps its IR and suite bytes
  (#564, #447).
• From format: ess/28 a branch requires several related rows at once, when_related: {all: [{via: input.<field>, predicate: …}, …]}, each row named by its own input identity and
  satisfying its own predicate: two ports both facing inbound refuse a wire in one branch. Validation
  partitions it with the other rows' branches and requires each row's exists: false answer; the
  interpreter reads every row; synthesis arranges each listed row to hold its predicate, the others
  beside it so that nothing answers first, and decoys around the first; the Rust, Go and
  TypeScript runners give one verdict on it. Generated Rust and Go keep the command an obligation
  and Entity Runtime lowering refuses it, each by name; below ess/28 it is refused naming
  ess/28 (downstream report 2026-10-19, finding 11).
• From format: ess/28 a value reads the lifecycle state of the row a reference names,
  {related: {via, field: state}}, typed as that entity's State: a refusal names the state that
  blocked it, and its scenario asserts the state the arranged row holds. Generated Rust and Go keep
  the command an obligation and Entity Runtime lowering refuses it, each by name; below ess/28
  it is refused naming ess/28 (#557, downstream report 2026-10-19, finding 9).
• From format: ess/28 a guard refuses a list of references naming a missing row,
  when_related: {via: input.<list>, exists: false} over a List<…> of one entity's identity
  (grid R's when_related: row, the existential over a list's elements of
  docs/design/generic-language-features.md § G2): taken when some element names no row, never
  for an empty list, and the refusal publishes the first such element with {missing: input.<list>}. The interpreter reads every element; synthesis sends the refusal a created row
  then an unknown identity and asserts the payload names the second, the accepting branch two
  created rows, and every other run of the command an empty list. A predicate: over the listed
  rows, a list in all:, a stored list and a list beside another related row are refused by
  name; generated Rust and Go keep the command an obligation and Entity Runtime lowering refuses
  it, each by name; below ess/28 the guard keeps its refusal, its hint naming ess/28
  (#558).
