- OntologyManager: remove red error banner on HTTP 500; always fall back
to empty state silently (error banners reserved for user actions only)
- AlignmentsTab: remove offline-backend warning when both registry and
alignments requests fail; show empty form silently
- ShaclStudio: fix Monarch tokenizer crash — [@] character class prevents
Monaco from misinterpreting @prefix/@base as language-property refs;
wrap beforeMount in try/catch so any Monaco setup failure cannot crash
the React tree
Decision workspace:
- Add AbortController per loadChain() call; abort previous request when a
new decision is selected, preventing stale out-of-order chain responses
- Guard all setState calls with signal.aborted so unmounted component
state updates are skipped; cancel in-flight request on unmount via a
dedicated cleanup effect
SPARQL workspace:
- Guard results table on both result.rows && result.columns to prevent
runtime crash when backend omits columns field
- Use (result.columns ?? []) inside rows.map() to satisfy TypeScript
narrowing inside the closure
- Add .catch() to clipboard.writeText() — silently swallows permission
errors (query remains visible in the editor as fallback)
- Fix CSV export anchor: append to body before click, remove after, to
ensure cross-browser compatibility
Import/Export workspace:
- Fix download anchor: append to document.body before a.click() and
remove afterwards, matching the standard compatible pattern
Lineage workspace:
- Replace 🔗 emoji empty-state icon with lucide-react Link2 for
consistent theming and sizing
Diff & Merge workspace:
- Add "Sample preview" banner above the mock diff table so users know
the displayed fields are illustrative until the backend is connected
OntologyManager:
- Restore non-blocking warning (flash message) when HTTP response is
non-OK and not a 404; network errors (backend down) stay silent
AlignmentsTab:
- When both registry and alignments promises reject, surface a soft
error banner so users know data is missing rather than just empty
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

Backend:
- Replace false conforms=True SHACL stub with status=unavailable always;
live validation cannot be wired until OntologyEngine.validate_graph is
connected to a data graph — a stub that returns conforms=True misleads
users editing shapes
- Cap node/edge fetches in health, suggest-alignments, and SHACL generation
at _MAX_ANALYSIS_NODES (5 000) with a logger.warning when the graph
exceeds the limit; unbounded limit=999_999 fetches cause OOM on large graphs
- Set SHACL health dimension score to 0.0 (was 70.0) when status=unavailable;
exclude unavailable dimensions from the total_score average so they neither
inflate nor deflate the result
- Allow alignments to reference external/unloaded URIs (e.g. schema.org)
without raising 404; label falls back to URI fragment or caller-supplied
source_label/target_label fields added to OntologyAlignmentRequest
- Fix _alignment_id to use uuid.NAMESPACE_OID instead of NAMESPACE_URL;
the composite key is not a URL
- Fix _summarize_shapes to normalise \r\n before splitting on .\n so shape
parsing works correctly on Windows line endings
Frontend:
- Wrap handleSave/handleSuggest/handleRemove/handleAcceptSuggestion in
useCallback in AlignmentsTab for consistency with sibling components
- Add ephemeral-storage banner in AlignmentsTab warning that alignments are
session-memory-only and not persisted across restarts
- Fix exportReport in HealthTab to append/remove anchor from document before
clicking and defer URL.revokeObjectURL to avoid Blob URL leak in some browsers
- Derive health dimension grid column count from health.dimensions.length
instead of the hardcoded repeat(5, ...) that breaks if the backend adds
or removes a dimension
- Add minimal Monarch tokenizer for the Monaco turtle language registration
in ShaclStudio so prefix declarations, IRIs, SHACL properties, comments,
and string literals are syntax-highlighted; previously the editor rendered
as plain text despite theme rules being defined
Tests (11 passing, was 5):
- Rename test_shacl_validate_has_stable_contract to
test_shacl_validate_returns_unavailable and assert status == unavailable
- Add test_shacl_validate_rejects_empty_turtle (expects 422)
- Add test_health_returns_404_for_unknown_ontology
- Add test_health_shacl_dimension_is_zero_when_unavailable with total_score check
- Add test_delete_unknown_alignment_returns_404
- Add test_alignment_upsert_is_idempotent (verifies ID stability and created_at
preservation across updates)
- Add test_alignment_accepts_external_uri (verifies no 404 for schema.org URIs)
- Relax test_alignment_suggestions_are_ranked label assertions to substring
checks so the test survives similarity algorithm changes

Bug 4 — Upload format misdetected:
- Added xml→'xml' and json→'json-ld' to the extension→format map so
.xml and .json files are no longer misidentified as turtle.
- Changed the fallback from '|| "turtle"' to '?? ""' (empty string for
unknown extensions) so the backend _detect_format() runs instead of
blindly assuming turtle for any unrecognised extension.
- Omit the format key entirely from the load request body when no format
was detected, letting the backend auto-detect from content heuristics.
- Added .n3 to the file picker accept list and dropzone hint text.
Bug 1 — Broken registry filters:
fetchRegistry no longer sends format/kind values (owl/skos/internal/external)
as the status query param; those filters are applied client-side via
filteredEntries which already had the correct logic. Only the text search
param q is delegated to the backend.
Bug 2 — Toggle/refresh URI corruption:
Removed removesuffix('/toggle') and removesuffix('/refresh') from
toggle_ontology and refresh_ontology. Starlette's route regex already
strips the literal suffix from the captured path param; the removesuffix
call was a no-op for normal URIs but corrupted any ontology URI that
legitimately ends with /toggle or /refresh.
Bug 3 — SSRF in URL fetch:
Added _validate_fetch_url() which rejects non-http/https schemes and
resolves the hostname to block private, loopback, link-local, reserved,
and multicast addresses before requests.get() is called. Applied to all
three fetch sites: preview, load, and refresh.
Bug 5 — Inconsistent XML hardening:
_parse_rdf_sync now calls _safe_parse_rdf() from
semantica/explorer/utils/rdf_parser.py instead of g.parse() directly,
applying the existing defusedxml-based XXE protection for RDF/XML inputs.
Bug 6 — Search scans whole graph:
search_entities now calls session.search(q, limit*6) which hits the
GraphSearchIndex instead of fetching up to 999,999 nodes and doing a
linear Python substring scan. Results are post-filtered by _SEARCHABLE_TYPES
and entity_type before being returned up to the requested limit.
- Replace invalid inset-left with inset: 0 0 0 72px on ::before at <=680px
- Add matching mobile inset fix to ::after (was still at 88px)
- Merge duplicate .landing-capability-band CSS rule blocks into one
- Fix non-standard font-weight: 850 -> 800 on .landing-launcher-item-title
- Remove unused eyebrow field from LandingAction type and all data entries
- Extract static 42-dot SVG preview array to module-level PREVIEW_DOTS constant

- 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

- Extract ENTITY_SHAPE_ALIASES and classifyEntityShape into a shared
graphEntityShape.ts utility — resolveEntityShape was duplicated with
divergent signatures in useLoadGraph.ts and graphSceneState.ts; both
now import from one place so aliases can never drift
- graphSceneState.resolveEntityShape falls back to classifyEntityShape
for nodes created programmatically that bypass useLoadGraph
- Fix graphTheme.ts indentation around fullGraphStructure,
fullGraphStructureLayer, and interaction — closing braces were at
wrong indent levels making the nesting visually misleading
- Add comment on fullGraphStructureLayer.mode explaining it is
intentionally "off" as a staged-rollout gate (flip to "auto" to enable
cross-community canvas curve rendering)

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.

- Extend PathResponse with hop_count (len(path)-1) and distance_band
("direct"|"near"|"mid-range"|"distant") as first-class API fields
- Add classify_path_distance() to semantica/utils/helpers.py as the
single source of truth for hop-count thresholds; both the route and
the visualizer import from it, eliminating duplicate threshold logic
- Populate hop_count and distance_band in find_path route via
classify_path_distance(); remove local _classify_distance() copy
- Add highlight_path: list[str] param to KGVisualizer.visualize_network;
path edges rendered as a distance-aware orange trace (opacity and
stroke width scale from direct→distant: 1.0/4px to 0.35/1.5px)
- Fix bidirectional edge lookup: only forward pairs (A→B) along the
path are added to path_edge_set; reverse back-edges in directed
graphs are no longer incorrectly highlighted
- Add logger.warning when highlight_path contains node IDs absent from
the layout position map, surfacing silent no-op mismatches
- Extend frontend PathResponse type in GraphInspectorPanel.tsx and
GraphWorkspaceShell.tsx with hop_count: number and distance_band
literal union to match the updated API contract
- Add 10 new tests: 2 API-level and 8 unit tests covering all four
band boundaries (0, 1, 2, 3, 4, 6, 7, 20 hops); 104 explorer tests
pass, 0 failures introduced
- Update CHANGELOG.md

- 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
