doomProductRelation

mutation · in the family Product relation

What it does

Permanently retire a product relationship — “goes with”, “replaces”, “upsell” links between products.

Doom (terminal) a ProductRelation by id; requires the unrestricted capability + the record's CURRENT revision. Deny-by-default + the referential_integrity / authority / occ guards; a doomed ProductRelation is immutable + never deleted. The optional reason rides the transition events.

Careful

Doom is forever — a doomed record never comes back into use (its history remains readable). Anything still referencing it live will block the doom.

Who may call it

Capability area: Catalog structure — Creating and retiring catalog families and whole items.

Arguments

NameTypeRequiredNotes
idID ID!yesThe id of the record.
revisionID ID!yesThe revision id you read on the record; the change is refused if an edit landed in the meantime.
reasonStringnoNo further notes.

Returns

ProductRelation ProductRelation! — A product relation — a TYPED, DIRECTED, RANKED suggestion edge between two Products (alternative | replacement | accessory | upsell | cross-sell — canned, AT-extensible). Parent = the SOURCE Product (relations die with their source); the TARGET is gate-protected from doom while suggested. Directed by design — symmetric intent = create both directions. Relation identity (source x target x relationType) is unique (a live duplicate is CONFLICT/IDENTITY_TAKEN naming the holder; a doomed one is taken over). Variant-level matching is DERIVED at read time — a later read-side slice.
