The producer-source refactor introduced the unreleased V4 discriminator code-mode even though this source identifies images deferred from successful PTC subcalls. Name it ptc-mode before V4 ships so persisted attribution matches the producer and does not freeze obsolete terminology into new logs. Keep the live writer, V3-to-V4 migration output, collision guard, and reserved producer policy aligned. Both released tools-code-mode and tools-ptc plugin lookup keys map to ptc-mode. Preserve those historical keys, opaque message text and IDs, all frozen V0-to-V3 generations, and recorded Session inputs. Update the owning tests, producer documentation, current catalog, and V4 acknowledgement. The canonical schema audit identifies exactly three changed roots; reversing only the source literal restores each prior digest. The large generated JSON diff comes from graph ordering, with 61 roots and 572 types retained. Validation: the seven-file focused run passed 298 tests and exposed four stale current-output expectations in two migration files. After correcting those expectations, both files passed all 23 tests. All 41 documentation gates and full lint passed; frozen generations and recorded inputs are unchanged.
