Both /chat/new drafts lose their TopBar — home's register now: drag
mask first in the DOM, floating sidebar-reopen toggle as the only
pointer-events-auto spot, the empty state carrying the orientation.
The chain picker's own bar then sits at the very top of the column,
exactly like the graph view — no stacked bars, no special-casing.
The chain table drops its 'Chains' title with it: the serif title
register is RESERVED — it always names a session; the table names
nothing, so its bar carries counts + search + close only.
Root cause of 'doesn't register': the slice-6 floating-bar edit never
landed (a silent no-match replace) — the Body accepted selectMode but
the bar ignored it, so the picker showed Clear + Delete and nothing
ever confirmed. Found by re-reading; the test suite never pinned the
select-mode bar.
The owner vision instead: the chain table's selection is PERSISTENT
and caller-owned.
- ChainTableOverlay gains controlledSelection/onSelectionChange (every
check, clear, and delete-prune reports up immediately; uncontrolled
fallback keeps the delete flow self-contained).
- Select mode's floating bar: Done (closes; the pick already
registered) — the delete fence never renders while picking.
- GraphView threads the lifted set through, resolving ids → nodes
against the live snapshot.
- Home: the pick bar above the composer shows 'N propositions
selected' + Clear in EITHER mode (dashed 'Pick propositions from the
map' hint only in practice mode with nothing picked); visible hover
(bg-accent) so the chip reads clickable. Practice sends still seed
from the pick set.
- Sidebar: the three-way kind filter (Teaching/All/Practice, persisted
in localStorage) above the search; two new-session doors (Teaching →
/chat/new, Practice → /chat/new?mode=practice); practice rows carry
the dumbbell badge and 'Practicing…' busy meta.
- Draft: ?mode=practice swaps the copy (title, empty state, 'What do
you want to practice?') and startDraftSession posts kind:'practice'.
- Graph entry (home composer): teach|practice switch on the stats row's
left edge (StatsBar leadingSlot); practice mode shows the propositions
chip that opens the chain table as a picker (its floating bar becomes
'Practice these' — no delete fence); the picks seed the opening prompt
('Propositions from the map:…') while the title stays the typed text.
Owner ruling 2026-10-04: the module is a sunk cost, retrievable from
history if ever revisited. Removed: core practice contracts + pipeline
helpers, the PracticeStore port + adapter + data dir path, server
service + API routes (sets, clusters picker, practice aborts), the
practice pages + dialog/exam/list UI, chain-table's Generate handoff,
sidebar nav, activity-dock practice rows, and the partitioner/
problemGenerator/grader model roles (BACKGROUND_MODEL_ROLES 8 → 5).
Survivors, moved to core/chains.ts (pure + browser-safe): ReasoningChain,
chainsForSelection, formatChainLine — the chain table and graph
emission still consume them.
Owner rulings 2026-09-30: reasoning chains are the stored truth; the graph
canvas renders a lossy derived image. No migration, no backcompat — old
graph data was wiped.
- contracts: GraphChain (arg_-minted id, premises, conclusion) replaces
typed edges; GraphEdge survives only as the untyped derived arrow;
GraphSnapshot carries stored chains; supports edges retired entirely
- store: chains.jsonl ledger (edges.jsonl purged at load alongside legacy
events.jsonl); readChains/appendChain seam; merge dedupes by
(sorted premises, conclusion), re-assertions append under the same arg_ id
- core: deriveView mints implication nodes (name ⟹, statement via
formatChainLine) plus premise→imp→conclusion arrows; clusters stay
proposition-only (birthSessionPartition); chainsForSelection now groups
STORED chains (chain rides iff every member selected) — independent
arguments for one conclusion never union; chainsToGraph/chainsToEdges die
- extraction: extractor submits chains natively (expandFindings deleted);
auditor receives propositions only; supports fan-out gone
- deletion: full death of a proposition kills every referencing chain;
arg_-prefixed node deletes kill that chain; chainsRemoved stats
- UI: every arrow renders the ⟹ double shaft; supports toggle + thickness
slider and detail-card edge sections deleted (card keeps name +
proposition); chain table + practice pipeline read stored chains
- tests: 1188 green across the new seams
'A → B → C' misread as chained implication when A and B are
CO-premises. The honest shape (owner, 2026-09-30): premises join
with the LaTeX LAND (∧), the conclusion separates by the LaTeX
IMPLICATION (⟹) — A ∧ B ⟹ C.
The glyphs are REAL KaTeX renders — components/latex-glyph.tsx wraps
katex.renderToString (cached per command; the app's math engine, the
stylesheet already rides app-wide from app/layout.tsx). No SVGs, no
font-dependent unicode. PROMINENT in the theme foreground (white in
the dark theme) per the owner's same-round ruling — the logic is the
payload, not the old dim gray. A lonely chip carries no glyph (it
reads as a standalone proposition); the plain-text '→' survives only
in the row's aria-label (formatChainLine, the screen-reader form).
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.
"This is really the view deletion should be done in" — the chain table
becomes the graph's MANAGEMENT surface. The floating selection bar
gains Delete FENCED at its right end (owner-approved placement): a
divider quarantines the destructive action from Clear and Generate,
red destructive pair + trash icon, opening the SAME full-death confirm
dialog the canvas uses.
DeleteNodeDialog extended from one node to an array:
- one node renders exactly as always; many pluralize the title
(Delete N propositions?) and list the names in the mono block,
capped at 8 + 'and K more'
- the pre-flight impact read aggregates: summed edge counts, unioned
referencing sessions (deduped, first-seen order); all-404 = gone
- confirm runs the per-node DELETEs SEQUENTIALLY — a failure stops
the run (extraction_running is never plowed through); onDeleted
now carries every id that actually died
- the chain table prunes its selection on delete and announces
lh:graph-revision so the snapshot refetches
Drift fix found en route (surfaced as NaN in the aggregated facts):
the server's NodeDeletionImpact has been {edges, sessions} only since
the quiz-events ledger died in the practice-arc schema slim — the
dialog kept rendering quizEvents/observations as undefined. The dead
fact lines are removed; the dialog now shows exactly what the server
can honestly report.
The tree threads no longer touch their arrows. Each thread is
BRACKETED by checkbox bottom edges (live-measured anchors):
- starts at its parent row's checkbox bottom edge — a visible gap
below the arrow's stroke (the stroke ends ~2.4px above the anchor)
- terminates exactly at the LAST child row's checkbox bottom edge
(cluster: top-[23px]/bottom-[8px] incl. the 1px group rule; chain:
top-[22px]/bottom-[8px]). Verified live: 23=23 top anchor, bottom
ends within 0.13px of the last checkbox at both levels.
- TREE THREADS: open folders and chains drop a vertical guide from
their expander arrow straight down through their children — at the
arrow's own column (37px clusters / 73px chains), subtle border/50.
Live-measured pixel-exact: arrow center = thread x (325=325, 361=361).
- The framed table: a rule under the header and under the last group
join the between-group separators; rows stay lineless.
Each staircase step is now TWO columns (36px): chains pl-12 — the
checkbox aligned with the cluster's FOLDER icon — and statements pl-21
— the checkbox where a chain icon WOULD sit (the chains lost theirs;
the pattern continues anyway). Live-measured: chain checkbox = folder
icon (336=336); statement checkbox = chain checkbox + 36 (372).
- chain rows lose the WaypointsIcon (owner: not needed — the chips +
connectors already read as chains); folders keep their icons.
- THE ALIGNMENT STAIRCASE: every level's checkbox sits directly under
its parent's expander arrow. The expander now shares the checkbox's
14px width (h-5 w-3.5), making each nesting step exactly 18px —
clusters pl-3 (12px) → chains pl-7.5 (30px, the cluster expander) →
statements pl-12 (48px, the chain expander). Live-measured: 318=318,
336=336.
- components/top-bar.tsx: THE shared top bar (standardization ruling) —
h-15, lh-drag + carve-outs, select-none, SidebarToggle reopen with the
Electron traffic-light gutter; adopted by chat (rename keeps its
drag={false} escape hatch), new-session, practice-list, practice-exam,
and the chains overlay.
- chain table: prominent indentation (pl-11 / pl-[4.75rem]), the ONLY
lines are the separators between cluster groups (row + vertical lines
gone), plain statement rows (no conclusion marker), all three columns
sortable (Props too) with a small chevron on the active header.
- full-bleed: blur + translucent surface IS the overlay, no inner card;
own top bar (info + search + close, lh-no-drag so home's drag mask
never eats the X — the clickability bug)
- three levels, one click each: cluster (birth session; a chain lives in
its CONCLUSION's cluster) → chain → proposition STATEMENTS revealed
directly (names never twice; singletons one click); all collapsed by
default
- proposition names as outlined chips, → connectors between; lonely chip
= standalone proposition — the '(no premises)' annotation is dead in
the visible UI (survives only as aria-label); Folder/Waypoints icons;
rotating chevrons; deep statement indent
- real table look: hairline row + column lines; sortable Name + Created
headers (click toggles asc/desc; size is text, not a control)
- selection never shifts layout: floating bottom bar (Google-Photos
pattern) with N propositions → M chains + Clear + Generate
- fuzzy search grouped + auto-expanding clusters
live-verified end-to-end on the owner's dev server; 15 rewritten render
pins; gates: tsc 0, 1179/1179, lint 0, build 0
- 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
