Two consumer-driven cures sharing one stamp. (1) TX-LOG ORIGIN: engine-
originated commits stamp an optional origin on their tx-log entry AND the
commit fact's meta — 'system:embed-landing' (the deferred vector landing),
'system:adoption-backfill' (baseline re-commits), 'system:reconcile'. A
downstream activity feed showed a double tick because the landing commit was
indistinguishable from a user save, and the consumer rightly refused a
time-window collapse as a quiet loss; feeds now filter on fact. User writes
stay unstamped — absent origin is the user shape, every existing consumer
unchanged. (2) reconcileLogDivergence(id, {attest}): the human's door for
log-live-canonical-absent, the one class adoption refuses by design because
a lost-tombstone deletion is indistinguishable from canonical loss.
'deleted' mints the missing tombstone (history keeps the earlier live
record); 'restore' folds the log's only copy back into canonical; wrong-
class calls refuse typed with nothing written. Loud, narrated, single-row,
origin-stamped. From a production adoption's one surviving divergence.
