Owner 2026-09-30: the confirm dialog's pre-flight impact read had to
go — what full death takes is obvious, the per-open fetch flickered,
and richer facts would only confuse as deletion semantics evolve
(rewiring is on the table). The screen is now: Delete node? / Delete
N nodes?, the names in the mono block, one permanence line, Cancel /
Delete. No loading state, no gone state (a 404 mid-run lands in the
honest failure line), no sessions join — the joins prop died too.
The dead path is deleted end to end: GET /api/graph/nodes/[id],
graphNodeImpact (server), nodeDeletionImpact (core) and their tests.
WORDING: node/node(s) is THE UI word for graph objects, standardized
across every surface's copy (owner, same ruling): the dialog titles,
the chain table's counts/search/summary/delete aria-labels, the
practice dialog's cluster counts, selection line, and empty-cluster
hint. Internal identifiers (selection.propositions) unchanged.
Rewritten dialog pins (tests/delete-node-dialog.test.tsx): minimal
contract — no facts/loading/fetch copy, singular/plural titles, the
cap, 409 dock phrasing, busy states, no 'proposition' left in the
dialog.
- 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
- dialog: optional 'Anything else?' textarea (typing-only, 2000-char mirror)
- API: body gains note? — trimmed, whitespace-only omitted, hard 400 over 2000
- pipeline: note persisted on the set and threaded to both agent stages
- agents: THE LEARNER'S NOTE prompt block (present only when set) + the
weighed-never-owed stance pinned in both doctrines
- fix en route: doubled THE PARAMETERS heading in both prompts since slice 3
(renderParams owns the heading; the literal blocks removed)
Contracts: LadderRung 0-4, CueDistance 0-2, Presentation theory|
application; PracticeParams carries the three named levels. Doc
comments hold the three definition tables verbatim (rung names +
definitions from the ladder doctrine; cue levels; presentation
levels).
Core: LADDER_RUNGS/CUE_LEVELS/PRESENTATIONS tables in src/core/
practice.ts (definitions verbatim) — ONE source spoken by the agents'
prompts, the dialog's stepped controls, and the exam header; core
barrel re-exports practice.ts (pure domain, browser-safe).
Agents: Part I's ladder intro now 'five rungs, numbered; the request
arrives as a rung' with bullets numbered 0-4 (definitions untouched);
Part III's parameters block replaced with the named-level doctrine
(rung = exact class, no continuum; cue counts lesson examples AND
previous problems' situations; presentation dresses, never changes);
partitioner's RESPECT THE PARAMETERS replaced (low rungs = many small
assignments, high = larger; far cue makes confusables-together MORE
important; presentation does not shape the partition). renderParams
outputs the exact named-level block. Anchor/0..1 language swept dead.
Service + store: strict union validation — floats between levels,
out-of-range, wrong strings, legacy dial shapes all 400 at the API
and fail isProblemSet (legacy sets skipped from lists; no migration —
data/practice is disposable scratch, owner wipes before testing).
UI: dialog = 5-detent ladder slider + 3-detent cue slider (each shows
the level NAME + one-line definition) + Theory|Application segmented
toggle; defaults rung 2 / cue 1 / theory; Create posts the new shape.
Exam header gains the levels line ('Direct exercise · Adjacent
context · Theory').
Tests: renderParams exact-block pin; strict-validation pins (new
tests/practice-service.test.ts — bad unions 400, legacy shape 400);
store pins (legacy floats + 2.5 rung fail); render pins (detents +
names + definitions, defaults, detent-swap, toggle active segment,
levels line); every params fixture moved off floats. 1138/1138, tsc
0, lint 0, build 0.
Docs: architecture.md — discretization paragraph (compact tables,
named-level invocation, defaults, one-table source), UI mentions;
README axes sentence.
Owner escalation on deviation 1: practice availability must not
inherit a visual-rendering threshold. graphClusters() now runs
birthSessionPartition(snap.nodes) directly (same size-desc/id-asc
ordering) instead of reading the snapshot's MIN_CLUSTER_SIZE-filtered
clusters array — MIN_CLUSTER_SIZE stays a hull-drawing rule only.
Label join mirrors the snapshot's (chat title / notes path, null when
the naming record is gone). Contract doc + architecture.md sentence
corrected to match; empty-picker copy reworded ('once a session births
its first proposition' — no 3+ mechanics). Render pins: new empty line
+ a 1- and 2-proposition group listing pin. 1130/1130, tsc 0, 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.
