Replace nearest-neighbour personal routing with a frozen class-balanced linear head measured on historical, stratified, cross-validation, holdout, and fresh challenge gates (V-702). Close the four repair handoff holes, preserve nested clarification flows, and route Russian possession statements through structural grammar rather than lexical exceptions (V-573). Owner explicitly requested direct commits to master.
The parseable twin of the owner's transcript goes green and loses its skip: Rome
is answered, the question survives the side query on the same attempt, and the
answer after it completes the reminder he actually asked for.
His transcript verbatim stays skipped, and V-561 was never going to unskip it.
What is left there is the parser — StubDateTimeParser reads neither "на 9" nor
"на завтра", so the third turn lands as an answer that filled nothing. The skip
reason now names V-543 and V-562 instead of this task.
Two V-560 tests asserted the drop notice and now assert the suspend: nothing
says a request was let go, the reply ends with the resumed question, and the
parked question is still there on attempt 1 with what it was about intact.

Push/peek/pop including that a peek does not consume and that the flow
under a popped entry survives; that a popped entry stays gone; that a push
past MaxStackDepth returns the evicted entry rather than dropping it
silently; that Put keeps the depth at one; that an expired top takes the
stack with it and is reported once by TakeExpired; and that two dialogue
ids do not read each other's stack.
