- core formatChainLine: names + arrow one-liner, singleton marker, pure
- graph-view Chains button (chrome row, empty-graph hidden) opens the
overlay: fuzzy search (names/aliases/statements), collapsible chain →
member → statement rows, birth-session + created columns, no
understanding-levels column
- pinned Selected section derives the agents' actual input live
(chainsForSelection over the selection; premise without its
conclusion shows as the singleton it becomes)
- Generate opens the creation dialog in CUSTOM mode: selection summary
+ dated default title, posts {nodeIds, params, note}; cluster mode
untouched on /practice
- live-verified on the owner's dev server: 219 chains, derived preview,
search-never-filters-Selected, dialog handoff (selection pass-through
bug caught + fixed en route), Esc/backdrop dismiss, zero writes
- practice UI files re-normalized to tabs (my earlier prettier runs had
drifted them to the 2-space default; whitespace-only)
17 render/unit pins added; gates: tsc 0, 1174/1174, lint 0, build 0

/**
|
||
* The exam page (practice slice 5, one-attempt redesign 2026-09-29):
|
||
* one problem set, numbered problems, markdown statements, a textarea +
|
||
* dictation per problem (the bar renders only on the FOCUSED box —
|
||
* thinking out loud is the primary answering mode). ONE ATTEMPT: each
|
||
* problem has its OWN submit button; once submitted the box locks and
|
||
* the MODEL SOLUTION reveals instantly (rubric collapsed by default).
|
||
* The grade (score 0–10 + brief reasoning) lands via the poll and
|
||
* updates live — no reload.
|
||
*
|
||
* TOP BAR (owner, UI round 2026-09-29): the chat pattern — an h-15
|
||
* lh-drag header in flow above the scroller, the sidebar reopen toggle
|
||
* first (it clears the traffic lights via .lh-closed-toggle), the set
|
||
* title truncating beside it. The levels + status stay in the body.
|
||
*
|
||
* DISPLAY-SEAM MATH HEALING: statements/solutions/rubrics/reasoning ride
|
||
* the same streaming-args parse as quiz/ask strings — restoreMathEscapes
|
||
* heals them at render (the same helper the tool-part seam uses).
|
||
*
|
||
* POLLING: 2s while the set isn't ready (stubs → filled), and while a
|
||
* grading run is live for this set (activity feed practice rows are
|
||
* keyed setId:grade:problemId — the LIVE rows name exactly which
|
||
* problems' grades are pending). A settled page goes quiet; a dropped
|
||
* grade shows "grade interrupted" honestly.
