- 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
Owner ruling: 'problem sets always take in nodes — graph objects' —
practice is graph-domain, not chat-domain. No session-created sets.
API: POST /api/practice/sets takes {nodeIds, params, title?} ONLY —
the chatId branch, UnknownChatError, and the any-provenance filter are
deleted; the selector is nodeIds (readNodes filtered to the selection,
unknown ids drop, empty live intersection → 400 empty_selection);
title optional from the UI (the picker's cluster label), dated default
stays. chatStore leaves the pipeline deps entirely (labels resolve
store-side in the clusters service).
GET /api/graph/clusters (new): the birth-session groups the graph view
renders — graphSnapshot's clusters verbatim (same ordering, same
MIN_CLUSTER_SIZE presentation filter), mapped to {key, kind
chat|notes, label (null when the naming record is gone — honest,
never guessed), nodeIds, nodeCount}; corrupt/empty graph → empty
list. GraphClusterGroup contract in core/contracts/graph.ts (client-
safe — the dialog imports it).
practice-dialog: session picker → cluster picker (rows show label +
proposition count, notes clusters marked); Create posts the cluster's
nodeIds + label as title + params. 400 empty-selection copy reworded
for the vanished-nodes edge ('Nothing practicable is left in that
cluster — the graph changed.'); 503 deep link unchanged. Preselected
mode gone — the dialog is the only creation entry for now (the graph-
view cluster entry comes later with free-form selection).
Sidebar: session right-click 'Practice this session's propositions'
removed (item + state + dialog wiring); the /practice nav row stays.
Tests: pipeline — chatId/any-provenance tests die, nodeIds selection
pins added (unknown-id filtering, dated-default title, title hint
rides, empty/vanished → EmptySelectionError); render — cluster picker
pins (label+count rows, notes kind, unlabeled cluster muted, empty
graph line), preselected pins removed; 16 render + 13 pipeline.
Docs: architecture.md §7 API+UI paragraph rewritten (graph-domain
ruling, /api/graph/clusters, cluster picker as the only entry, no
404-unknown-chat); README creation-flow line updated.
1130/1130, tsc 0, lint 0, build 0.
components/practice-dialog.tsx: portal dialog (delete-session shape),
three dial rows (SettingSlider markup, anchor text as display:
flashcard-competition / near the lesson-far transfer / theory-
application, defaults 0.5), session picker (generic mode, /api/chats)
or preselected lock (right-click path); 400 empty_selection renders
'This session has no propositions yet', 503 renders the server line +
Open settings deep link (useSettingsDialog, zero-keys precedent).
Pure body exported for SSR pins.
components/practice-list.tsx: rows (title, date, ready/total problems,
graded count, status word; destructive tint on error), click-through,
delete affordance → portaled confirm (DeleteSetBody: no mode checkbox
— a set has no preserve-graph question), 2s reveal-poll while any set
is partitioning/generating. components/practice-exam.tsx: numbered
problems; generating stubs (BrailleSpinner + 'Generating problem…',
propositions never surface); ready statements/solutions/rubrics/
feedback as MessageResponse markdown with restoreMathEscapes at the
display seam; per-problem textarea + useDictation instance with the
DictationBar rendered only on box focus; one Submit answers POST per
set; graded reveal (verdict chip, feedback, model solution, rubric)
with read-only answer; polling while not ready OR grading-live
(activity feed practice rows — dropped grades terminate the poll).
app/practice/page.tsx (force-dynamic, listPracticeSets) + app/practice/
[id]/page.tsx (getPracticeSet + notFound). Sidebar: quiet Practice nav
row under New session (GraduationCapIcon, active on /practice) +
'Practice this session's propositions' in the session right-click
below the hairline, above CoverageMenuBlock — opens the dialog
preselected.
tests/render-practice.test.tsx — 15 pins: dials + anchors, picker
selection gating, preselected lock, empty-selection line, 503 deep
link, list rows/counts/empty, delete confirm + inline failure, exam
generating (no proposition text, no answer boxes, no submit), ready
(markdown statement, gated submit), graded reveal + read-only + sibling
answerable, failed problem/set lines, math healing. 1129/1129, tsc 0,
lint 0, build 0.
