Measure what the two clarify bounds bought (V-663)

Tail turns 21 to 17, the longest ride 8 turns to 4, and the two worst replies in the corpus are gone: "спасибо" and "привет" are no longer answered with "Сейчас 21:25. В какой день?". MaxRides is not what fired. With the pleasantry counted as an aside the run of asides is unbroken, so MaxSuspends reached three and ended it. Rides is the backstop for the shape where an answer really does break the run, and no turn in this corpus reaches it. Said so rather than crediting the new bound. Four rides did not move. They are asides against a question the owner never answers, which MaxSuspends already bounds at four turns each.

+# The parked clarify ride, bounded and re-measured
+
+Date: 2026-08-08, V-663. Same 140 turns, same driver, third and fourth runs of
+the day. Before is `d6f3914`, after is that plus two changes.
+
+## What was measured before
+
+One question about a reminder's day rode turns 6 to 13. It ended only because
+turn 14 was a new request. Two of those turns are the worst replies in the
+corpus:
+
+```text
+спасибо   -> Сейчас 21:25. В какой день?
+привет    -> Сейчас 21:25. В какой день?
+```
+
+V-654 had already added `MaxSuspends` and the tail count had not moved.
+
+## Why three bounds let it happen
+
+The TTL, `MaxAttempts` and `MaxSuspends` all exist and all were rearmed.
+
+An aside spends no attempt, so `MaxAttempts` never reaches it. A turn reading as
+a failed answer zeroes `Suspends`, so `MaxSuspends` never reaches the asides.
+`спасибо` read as a failed answer. So the pleasantry both produced the reply
+above and paid for it out of the budget meant to end the ride.
+
+## The two changes
+
+`PendingQuestion.Rides` counts the same event as `Suspends` with the resets
+taken out. Set once, incremented only in `noteSuspended`, carried across the
+re-park in `askRemainingGap`. `MaxRides` is 4, one looser than `MaxSuspends` so
+that the tighter statement about a run stays reachable.
+
+A pleasantry is an aside, not a failed answer. The set is a new closed lexicon
+entry, matched as whole utterances rather than tokens. `вечер` answers `это утра
+или вечера?` and `нет` answers a confirm. Anything that could fill a slot stays
+out.
+
+## Result
+
+| | before | after |
+|---|---|---|
+| turns carrying a clarify tail | 21 | 17 |
+| turns carrying any failure string | 31 | 29 |
+| the longest ride | 8 turns | 4 turns |
+
+The turns carrying a tail, by number:
+
+```text
+before  6 7 8 9 10 11 12 13   53 54 55 56 57   99 102 103   116   136 137 138 139
+after   6 7 8 9                53 54 55 56 57   99 100 101   116   136 137 138 139
+```
+
+Turn 10 is the change. It now reads:
+
+```text
+спасибо -> Прошлую просьбу отпускаю. Пожалуйста, я всегда готова помочь тебе.
+```
+
+She lets the request go, says so, and answers the man. Turns 11 to 13 are clean.
+
+**`MaxRides` is not what fired.** The pleasantry is an aside now, so it no
+longer breaks the run. `MaxSuspends` reached three on turn 10 and ended it.
+`Rides` is the backstop for the shape where an answer really does break the run.
+No turn in this corpus reaches it.
+
+## What did not move
+
+Four rides are untouched. Turns 53 to 57 are five consecutive asides against a
+reminder missing its day. Turn 58 is a new request that drops it. Nothing
+pleasant appears in that run, so neither change applies. Turns 99 to 101 shifted
+by one, and 116 and 136 to 139 are unchanged.
+
+So the fix is worth four turns of twenty-one. What is left is asides against a
+question the owner never answers. `MaxSuspends` was written for that shape and
+does bound it, at four turns each.
+
+## Not attributable
+
+Latency moved p50 1.1s to 1.5s and p95 2.8s to 3.0s, and the 34.3s outlier in
+the earlier run is gone. Both runs had the workstation up. Read none of it as
+caused by this change.
+
+One unrelated defect appeared in the after run and is recorded here because it
+is visible in the transcript. Turn 4 answered `Я записала твою привычкуRegarding
+coffee without sugar.` That is English leaking into a Russian reply with no
+space in front of it. It is a phrasing defect and it has no task yet.
