- Wire the Explorer frontend's node --test suites (test:graph-store,
test:graph-workspace, and the new test:plugin-registry regression
test) into CI. Previously only `npm run build` ran, so none of the
frontend tests -- including this fix's own regression coverage --
executed anywhere except a contributor's local machine.
- Broaden the diagnostics dedup's structureLayer comparison to also
cover disabledReason/curveCount/bridgeCurveCount/backboneCurveCount,
not just cacheKey/lastDrawAt/enabled, so a disabledReason-only
transition doesn't leave the dev diagnostics panel stale.
- pluginRegistryPredicates.ts: consolidate 8-line JSDoc to 5 lines,
removing redundant detail that restated implementation mechanics
already obvious from the code.
- GraphWorkspace.tsx: shorten the lastScrubberMsRef comment from 5 lines
to 2; trim the handleDiagnosticsChange block comment by removing the
'rather than bailing out' implementation-alternative sentence; tighten
the distanceVisual inline comment.
- pluginRegistry.temporal.test.mjs: replace 17-line file-level JSDoc
with 9 lines focused on the invariant rather than the root-cause
narrative (already covered in pluginRegistryPredicates.ts); remove
two tsx loader implementation-detail comments; tighten two test-level
inline comments.
No logic, types, or test assertions changed. All 42 tests pass.
Two issues addressed:
1. Plugin-loading useEffect unnecessarily depended on temporalState.
After the #830 fix, no shouldLoad predicate reads temporalState, but
the effect's dep array still included it, causing extra re-runs on
every scrubber update. Removed temporalState from the dep array and
the shouldLoad call site. Made temporalState optional in the
LazyPluginRegistryEntry shouldLoad context type to match.
2. Regression test imported a local copy of shouldLoad instead of the
production predicate. Extracted all three shouldLoad predicates into
pluginRegistryPredicates.ts (pure module, no React/DOM dependencies),
wired GraphWorkspace.tsx to use the imported functions, and updated
the test to import and exercise the real production code via tsx.
Verified: introducing the old broken condition causes the test to fail;
the correct implementation passes all 7 assertions.
Two independent render loops were causing the Temporal panel to remain
stuck on 'Loading temporal...' in npm run dev:
Loop 1 — diagnostics state churn (GraphWorkspace.tsx):
handleDiagnosticsChange unconditionally called setGraphDiagnosticsState
with a new object on every invocation. buildEffectAvailability (called
inside GraphCanvas's diagnostics useEffect) always returns a new object,
so setGraphDiagnosticsState was called on every effect run, creating a
cycle: setGraphDiagnosticsState graphDiagnosticsState new
diagnosticsSnapshot new pluginContext new handleInteractionStateChange
new GraphCanvas re-renders diagnostics effect fires again.
Fix: before calling setGraphDiagnosticsState, compare the incoming
diagnostics field-by-field against the last accepted snapshot via a ref
(lastDiagnosticsRef). All effectAvailability entries, edgeClasses.updatedAt,
structureLayer.cacheKey/lastDrawAt/enabled, and distanceVisual identity
must differ for a state update to proceed. The ref approach avoids
scheduling a re-render at all, rather than bailing out inside a functional
updater after the render has already been committed.
Loop 2 — scrubberTime churn (GraphWorkspace.tsx + GraphWorkspaceShell.tsx):
TimelinePanel.tsx calls onTimeChange(defaultTime) whenever its useEffect
re-runs. React 18 concurrent mode re-runs effects with structurally-new
Date objects for the same timestamp when speculative renders discard
useMemo caches, causing setScrubberTime to be called repeatedly with a
new Date that has the same millisecond value — triggering temporalState
churn, the diagnostics effect, and eventually the same loop.
Fix: wrap setScrubberTime in an onTimeChange useCallback that compares the
incoming time's millisecond value against the last sent value (via
lastScrubberMsRef). Redundant calls with the same timestamp are dropped
before reaching setScrubberTime. Stable useCallback identity also prevents
TimelinePanel's useEffect from re-firing solely due to prop identity churn.
Both fixes applied to GraphWorkspace.tsx and identically to
GraphWorkspaceShell.tsx which has the same pattern.
Verified:
- npm run dev: 0 'Maximum update depth exceeded' errors
- Temporal panel renders with real data in dev mode
- Effects and Neighbors panels unaffected
- npm run build + preview: identical behavior, 0 errors
- All 42 frontend tests pass (34 graph-workspace, 1 graph-store, 7 plugin-registry)
Backend (semantica/explorer/routes/ontology.py):
- suggest-alignments: add TF-IDF character-ngram embeddings via sklearn
(SimilarityCalculator-compatible cosine scoring) so embedding_similarity
is populated in results; combined score = 0.4*label + 0.6*embedding when
available, falling back to label-only when sklearn is absent
- suggest-alignments: add token-overlap prefilter before SequenceMatcher so
zero-Jaccard pairs are skipped without computing full similarity; add
_MAX_ENTITIES_PER_SIDE=500 per-ontology cap on top of the existing
_MAX_ANALYSIS_NODES global cap
- suggest-alignments: remove dead try/except OntologyEngine.create_alignment
block that always failed silently (no TripletStore configured); replace
with a comment explaining the intentional ephemeral-only storage model
- health: replace O(alignments x entities) any() scans for alignment coverage
with O(1) set membership checks via assessed_ids
- shacl/validate: run rdflib.Graph().parse(format='turtle') syntax check on
the submitted Turtle before returning; invalid syntax now raises 422 instead
of returning a misleading unavailable/success response
Frontend:
- AlignmentsTab: add pairwise alignment matrix section that groups recorded
alignments by (source_ontology, target_ontology) pair; each cell shows
color-coded relation badges per RELATION_COLORS; clicking a badge populates
the create/edit form for quick editing; matrix is shown when at least two
ontologies are loaded
- ShaclStudio: add selectedShapeId state and fullShacl ref; each shape row in
the library is now a clickable button that extracts its Turtle block from
the full SHACL and pre-populates the Monaco editor; a "View all" toggle
restores the full SHACL; selected shape ID is shown in the editor header
- GraphWorkspace: fix viewMode race in external focus effect — call
setSelectedNodeId directly instead of going through focusNode(), which
captured a stale viewMode in its closure; remove focusNode from the
dependency array since it is no longer called
Tests (14 passing, was 11):
- Add test_suggest_alignments_returns_embedding_similarity: asserts
embedding_similarity is non-null when sklearn is available
- Add test_shacl_validate_rejects_invalid_turtle_syntax: asserts 422 on
syntactically invalid Turtle
- Add test_health_alignment_coverage_uses_set_lookup: asserts alignment
dimension score is non-zero after recording an alignment, verifying the
O(1) set lookup path works correctly end-to-end

- Fix dead `if (anchorNodeId)` conditional in buildHeatmapRenderSnapshot
(anchor is always truthy past the early-return guard on line 263)
- Replace O(n) array .includes() with WeakMap-cached Set.has() in
resolveDistanceNodeStyle heatmap path — prevents per-node O(n) scan
during every Sigma reducer pass on large graphs
- Rename GraphDistanceBucketCounts.threeHop → threeHopPlus across
types.ts, graphSceneState.ts, and GraphWorkspace.tsx so the field
name reflects that it accumulates distance ≥ 3, not exactly 3;
update status-strip labels to "3+ hop" accordingly
- Restore hasMetrics guard in PathDistanceIntelPanel to suppress the
empty metric grid <div> when a path result carries no optional metrics

Merge origin/main (Distance Intelligence #502) into feat/explorer-visual-refresh.
Conflict was in the viewModeItems useMemo: the PR's new cluster-based toolbar
structure diverged from main's coreToolbarGroups additions.
Resolution:
- Keep PR's viewModeItems as a clean 3-item segmented control (Full/Grouped/Focused)
- Port Distance Intelligence controls (ego mode, heatmap, structural/semantic overlay)
into a new distanceToolbarItems useMemo that slots into the cluster toolbar as a
"Distance" cluster, visible only when a node is selected
- Wire distanceToolbarItems into toolbarClusters between "local-structure" and
"analysis" clusters
- All other Distance Intelligence additions (state vars, BFS helpers, useEffects,
ego depth slider, GraphInspectorPanel onFocusNode prop) merged cleanly

- Fix `import.meta.env.DEV` crash in graphSceneState.ts that broke the
entire test:graph-workspace suite (module load fails in Node.js/tsx)
- Export `resolveGroupedDisplayNodeId` from graphSceneState.ts and
remove the identical copy in GraphWorkspace.tsx
- Add `checkGroupedViewAvailability` helper (Louvain only, no centrality)
so grouped view availability can be checked cheaply on every graph change
- Gate full community graph build (`groupedDisplayCandidate`) on
`viewMode === 'grouped'` to avoid running Louvain + centrality on every
graph version tick when the user is not in grouped view
- Remove dead ternary in `focusNode` where both branches returned `nodeId`
- Add 7 new tests covering resolveGroupedDisplayNodeId,
resolveGroupedDisplayStateSnapshot, and checkGroupedViewAvailability

Merge conflict resolution:
- Kept fix/graph-motion's conditional layout-stop (only in focused mode)
to preserve live layout motion for derived graphs — the core intent of
this PR.
Must-fix items resolved:
1. plugin.json — removed "hooks": "./hooks/hooks.json" (re-added by this
branch, already removed in PR #489 on main as it is auto-loaded).
Kept "agents": "./agents".
2. Double Louvain per render — added groupedViewAvailable useMemo in
GraphWorkspace (deps: [graphVersion]) that runs community detection
once. Passed result into resolveDisplayGraph and resolveDisplayStateSnapshot
via new groupedViewAvailable option; both functions skip their internal
computeGraphAnalyticsBase call when the value is pre-supplied.
3. graphVersion in displayState deps — removed graphVersion from the
displayState memo dep array. displayState now depends on the stable
boolean groupedViewAvailable, not on every ADD_NODE/ADD_EDGE tick,
so Louvain no longer re-fires on every WebSocket update.
4. hideLabelsOnMove / hideEdgesOnMove flipped to true — intentional:
suppressing labels and edges during pan reduces visual noise and is
part of the flicker-reduction fix described in the PR.

1. Prevent active-but-disabled Focused button by only disabling when
viewMode is not already "focused" (viewMode !== "focused" && !canActivateFocusedMode).
2. Generalize inspector fallback copy — stale/invalid node IDs are not
necessarily grouped items, so remove the misleading "Activate Focused
mode" hint.
3. Move pluginRuntimeRef.current read out of render by converting
canActivateFocusedMode from useMemo to useState + useEffect, resolving
two ESLint "cannot access refs during render" errors and the missing
toolbar-memo dependency warning.

- GraphWorkspace: set isRunningPredictions=true before link-prediction fetch
and false in finally block; pass isRunningPredictions prop to
LazyGraphInspectorPanel so the inspector button disables and shows a
spinner during the request (was declared but never wired — broke
noUnusedLocals TypeScript build)
- DecisionWorkspace: add AbortController to the /api/decisions useEffect
so the fetch is cancelled on unmount; add per-call AbortController to
handleSelectDecision for /api/decisions/:id/chain; add res.ok guards
before .json() on both fetches; encodeURIComponent on decision_id to
prevent path-injection edge cases
- index.css: add missing @keyframes skeleton-pulse rule (0%/100% opacity
0.45, 50% opacity 0.85) — KGOverviewTab skeletonBarStyle referenced
this animation but it was never defined, leaving skeleton bars static
