Keep targeted existence questions as A-D cards. Recover collect-schema
stock by question-id prefix, surface the stem when persist fails, and
send spoken targeted existence to the repair exit instead of a naked prompt.
GET dropped the A–D card when the recast had no choice_frame, so a refresh left a disabled card and a collect-wait. Project from the persisted copy, rebuild the keep frame, and send a dead choice to repair-exit.

Empty engine refresh now records an already_answered attempt so GET can leave wait-to-narrow; collect kinds map onto the table CHECK; remaining candidates drive probe refresh.

When dated choice probes are exhausted after the training gate, stop treating yearless D9/D10 cards as the next discriminator and persist a range carrier in the same answer transaction.

Stop domain-wheel collecting and age-band years in prompts. Ask until the training gate, then discriminate until convergence, then deliver a range plus a concrete follow-up. Reserve holdout only with four dated events.

Evidence turns that already recorded a batch no longer fail the whole run when the model emits no text; unchanged ranges now name which clock spans lead or lag, and the timeline no longer says 收窄.

The range is the only quantity that expresses convergence, and it existed
only as a sentence in the transcript. The bar makes it permanent.
It is the chat grid's first row, outside the scroll container, so
scrollHeight is untouched and use-conversation-scroll-anchor needs no
change. Its height is fixed because nothing observes it: a growing bar
would alter clientHeight and let an anchored reader lose the tail.
The axis is the current search window, not the opening one, since
widening overruns the opening window. Marks are binary — in range or
excluded — because relative support between candidate minutes carries no
demonstrated minute-level discrimination (BUG-560, blocked).
Band and marks move by transform alone; globals.css bans width
transitions, and transform keeps the motion off the layout path.

Keep askable cards after exhaustion, explain each probe, read the adopted credible range in reports and chat, and compare declared periods before the minute grid when the clock is unknown.

Enter now queues one follow-up instead of dropping it, and a rectification stop leaves the streamed reply with a grey notice instead of an error alert.

Adopted reverse-verify repeated already-asked collect stems, treated 「这题跳过」 as stopping the case, and promised holdout/OOS checks that never ran. Collect spoken stems no longer prefix a year.

The chat used to show "当前没有可回答的问题，正在等待服务端更新" / "当前问题暂时无法显示"
/ "题目加载失败，请刷新" as bare copy above the composer. The gap between a
settled turn and its next question is now a state: `preparing` renders the
same timeline live row the reply uses ("正在准备下一个问题…") and refetches the
Case on a 2s timer up to two retries; `unavailable` renders one line and a
44px reload button. A snapshot that never arrived at hydration is the same
gap. A resumed Case with no turns and no server-started opening shows
"这段校正还没有开始。" with one 开始提问 action. Stopping a run keeps what
streamed and says so instead of "暂时不可用"; the opening turn's live row
names what is happening; a 402 explains itself for 600ms before leaving.

Opening a rectification Case used to switch sessions first and read the
turns afterwards, so the reader saw a plain transcript, then an empty
panel, then a remount when the turns arrived (and again after the first
turn settled, because the panel key carried a ready/loading suffix).
The surface hook now reads turns and snapshot in one Case request under
the home reveal budget and only then makes the session active; the
sidebar defers the switch the same way; a session selected at bootstrap
(deep link, refresh) is hydrated during the prepare phase so the reveal
shows the surface itself; the panel key is the session/Case binding only,
later turns fill an empty transcript as a prop update, and unmounting
aborts any stream or snapshot read. The homepage card and the sidebar row
say 正在打开 statically while the Case opens — no spinner after the reveal.
