DL-343

Forge transition actor attribution rides a CONSUMABLE forge_state_transitions memo, never a parsed-text or author-row proxy: written after a successful transition at the same attribution chokepoint every forge write rides, then consumed on match at the notify lane so the provider-echoed STATE event resolves to the acting agent. Tenant-scoped like its forge_authored_artifacts sibling, and fail-open on a miss (a late webhook loses attribution; it never blocks or misattributes). This is the contract surface the RIG-3326 self-origin suppression record’s STATE arm keys on, and it settles that cross-record question in the memo’s favour: RIG-3326’s frozen text describes the actor as stamped onto the emitted event, so its STATE arm bends to a memo lookup at the actor-resolution seam. The rejected alternative was a synthetic STATE event emitted at the chokepoint — equivalent for the suppression outcome, but it invents an event the forge never sent. Landing the seam is what closes RIG-3326’s interim-open STATE arm.
