The pattern detector needs four events for one action+object spread by at least two hours before it proposes a routine. The only writer in the tree is a fact write at time.Now(), so V-43, V-46, V-247 and V-254 all stopped at the same missing step. This is the wire half of the seam that unblocks them. The request takes a fact — key, value, timestamp — not an event, so pattern.Extract runs for real on the daemon side and a key the extractor ignores seeds nothing. The response says which of those happened, because a caller that assumed a seed always yields an event would read four silent successes as a broken detector. AuthStepUp, the same rung as mutating the tool allowlist, and not because backdating is privileged in the usual sense: every other write records when something happened and this one asserts it. StoreAPI refuses outright — the method needs the daemon's detect-and-propose step, and a direct store caller would write a fact and quietly skip it.
