* fix(explorer): resolve blank dashboard UI and ship frontend bundle in wheel
Fixes#631 — the Explorer server started successfully but the browser showed
a blank page because semantica/static/ was gitignored and never present after
a fresh install or clone.
Changes:
- ci.yml / release.yml: add Node 20 setup + npm ci && npm run build before
python -m build so every wheel contains a CI-built frontend bundle
- pyproject.toml: add package-data patterns (static/*, static/assets/*) so
setuptools includes the bundle in the wheel; add MANIFEST.in for sdist coverage
- app.py: replace silent empty-HTML fallback with a 200 page that clearly
explains the missing bundle and links to /docs; fix CORS allow_credentials
to default false, gated behind EXPLORER_CORS_CREDENTIALS env var to prevent
credentialed cross-origin requests on unauthenticated endpoints
- __init__.py: warn at startup when --host is non-loopback (unauthenticated
network exposure)
- explorer/README.md: full rewrite covering pip-install mode (primary path,
no Node required) and dev-server mode (contributors), CLI flags, env vars,
workspace table, troubleshooting for the blank-page symptom
- README.md: update Knowledge Explorer section with correct command and link
to the new setup guide
* fix(explorer): set build.target esnext to fix esbuild CI failure
esbuild >=0.28 (forced via npm overrides) conflicts with Vite 6 defaults on
Linux CI — it tries to lower destructuring syntax for the implicit browser
target list but errors out. Explicit target: 'esnext' tells esbuild to emit
native syntax unchanged, bypassing the transpilation error entirely. Safe for
a developer tool that runs in modern browsers.
* test(explorer): verify packaged frontend bundle

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

- Align _coerce_embedding_vector inner dict-probe key list with
_extract_node_embeddings outer key list (add 'embeddings', reorder to
generic-first) so nested embedding dicts resolve consistently.
- Add TODO comment on _extract_node_embeddings to cache per-session
graph revision and avoid O(N) re-scan on every semantic request.
- Add deprecation docstrings to legacy path-segment routes
(/node/{id}/path and /node/{id}/semantic-neighborhood) documenting
the known slash-in-ID limitation and pointing to the query-param
alternatives.
- Extract _FakeSimilarity to module level so it is shared without
duplication across test classes.
- Rewrite test_legacy_semantic_neighborhood_still_works_for_simple_ids
as a fully isolated TestClient session instead of mutating the
shared module-scoped 'client' fixture, preventing cross-test
state pollution.
- Extract _make_slash_node_session helper to reduce boilerplate in the
slash-safe route tests.

- 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
- PathFinder.bfs_shortest_path() and dijkstra_shortest_path() gain a
directed: bool = True parameter. When False, a temporary undirected
view (graph.to_undirected()) is used for traversal only; the original
directed edges are preserved and returned in the response.
- _make_undirected_view() helper added to PathFinder; falls back safely
for non-NetworkX graph types.
- GET /api/graph/node/{id}/path exposes ?directed=false query param.
- PathResponse gains a directed: bool field echoing the mode used.
- Route now returns 404 on empty path (previously returned 200 with
path: []).
- 21 new tests: 12 unit (TestBidirectionalPathFinding) + 9 API-level
(TestBidirectionalPathRoute). All 120 tests pass.
- CHANGELOG updated under [Unreleased].

- routes/graph.py: raise HTTPException(404) for missing nodes; wrap path_finder call in try/except → HTTPException(404)
- routes/decisions.py: raise HTTPException(404) on chain, compliance, precedents sub-routes
- routes/annotations.py: raise HTTPException(404) on create (missing node) and delete (missing annotation)
- routes/enrich.py: raise HTTPException(404/503/422) for missing nodes, unavailable services, and extraction errors
- routes/temporal.py: fix TemporalPatternDetector method name detect_patterns → detect_temporal_patterns
- explorer/app.py: root / now serves built index.html when available, falls back to minimal HTML shell; add HTMLResponse import
- tests/explorer/test_explorer_api.py: test_extract accepts 503 (spacy/transformers not installed is a valid service state)
All 45 explorer API integration tests pass.

- test_vocabulary.py: remove sys.modules['spacy'] = MagicMock() — caused
ValueError in pytest collection when transformers called
importlib.util.find_spec('spacy') on a MagicMock without __spec__;
add setup_function() reset_mock() to prevent cross-test state pollution;
expand from 3 to 16 tests covering narrower edges, topConceptOf,
hasTopConcept, flat scheme, empty scheme, missing param, cycle safety,
.rdf/.owl format path, invalid file 422, and metadata envelope fallback
- vocabulary.py: /import returned HTTP 200 with {"status":"error"} on parse
failure — now raises HTTPException(422) so clients get a proper error code;
replace bare except with ValueError-specific catch, move add_nodes/add_edges
outside the try block
- vocabulary.py: get_hierarchy tree assembly had no cycle detection — cyclic
broader/narrower edges in real-world SKOS data would cause infinite recursion
during Pydantic serialization; replaced inline loop with recursive
_attach_children() that carries a visited set
- semantica/explorer/utils/: branch was based on main and missing rdf_parser.py
and __init__.py (introduced in #425); copied from ebd2be3 so vocabulary.py
import resolves correctly
- tests/explorer/test_rdf_parser.py: carried forward from #425 (32 tests)

app.py:
- Fix unclosed '(' in generic_error_handler (two implementations were merged,
leaving the return JSONResponse( call with no closing paren)
- Remove duplicate 'from fastapi import FastAPI, Request' import
- Remove unused 'import traceback'
- Remove duplicate static file mount (was mounted twice: once conditionally,
once unconditionally creating the dir — FastAPI raises on duplicate mounts)
decisions.py:
- Remove stub 'return ComplianceResponse(compliant=True)' with unclosed '('
that was left in front of the real edge-scan implementation
temporal.py:
- Remove blocking get_nodes/get_edges calls (without asyncio.to_thread) that
were left as dead code above the correct async versions
- Fix empty 'except Exception:' clause before 'except ImportError:' that
caused a SyntaxError
tests/explorer/test_explorer_api.py:
- Remove all merge-artifact duplicate class definitions (TestAnalytics x2,
TestReasoning x2, TestAnnotations x2) — Python silently used the second
definition, hiding the first; collapsed into single canonical classes
- Fix test_snapshot_at referencing undefined 'body' (no request was made);
merged its assertions into test_snapshot_now
- Fix test_compliance asserting isinstance(body, list) on a dict response;
the displaced precedents-check code is now in test_precedents where it
belongs
- Fix test_compliance_with_violation using wrong session reference
- Remove duplicate node-lookup and duplicate assertions throughout
- Add test_search_content_populated: asserts search results carry non-empty
content (regression guard for the to_dict envelope fix)
- Add test_import_edge_metadata_preserved: asserts edge metadata survives the
import round-trip (regression guard for the properties/metadata fallback fix)
All 51 tests pass.

Bugs fixed:
- enrich.py: predict_links called predictor.predict_links() with wrong
signature (graph_dict as graph_store, node_id as node_labels, top_n
instead of top_k). Rewrote to iterate candidate nodes and call
score_link(session.graph, src, candidate) directly.
- enrich.py: detect_duplicates called session.get_nodes() synchronously
in an async handler, blocking the event loop. Wrapped in to_thread().
- export_import.py: temp file was leaked on export exception. Now always
cleaned up via try/finally. Moved `import os` to module level.
- pyproject.toml: missing comma between two strings in the `all` extra
caused a TOML syntax error breaking `pip install semantica[all]`.
- app.py: generic Exception handler swallowed HTTPException(503) raised
by get_session dependency. Now re-raises HTTPException explicitly.
- decisions.py: compliance endpoint imported PolicyEngine then discarded
it, always returning compliant=True. Replaced with in-graph check:
scans for violates/non_compliant/breaches edges from the decision node.
- app.py: removed unused `import traceback`.
Refactor:
- session.py: added build_graph_dict(node_ids=None) method to eliminate
_build_graph_dict() duplication across graph.py, analytics.py, and
export_import.py (three identical copies).
- session.py: all 8 lazy analytics properties now initialise under _lock
to prevent double-instantiation under concurrent requests.
- graph.py: find_path now dispatches to dijkstra_shortest_path or
bfs_shortest_path based on the `algorithm` query param (was always BFS).
- annotations.py: removed unnecessary get_annotations() round-trip in
create_annotation — add_annotation mutates ann_data in-place.
- temporal.py: split bare `except Exception` into ImportError (silent)
and Exception (logs warning), so real bugs are no longer hidden.
Tests (49 total, all passing):
- Added TestEnrichExtract, TestLinkPrediction, TestDedup classes.
- Added test_compliance_with_violation to verify real violation detection.
- Added test_snapshot_at_excludes_temporal_node, test_diff assertions,
test_export_json_subset, test_import_with_edges, test_import_unsupported_format.
- Strengthened analytics, search, and annotation assertions.
- Reasoning test now asserts response shape when status is 200.
