- Convert mcp_server.py to package structure (semantica/mcp_server/)
- Add __init__.py and __main__.py for python -m support
- Add semantica-mcp console script entry point in pyproject.toml
- Fix API method calls (extract -> extract_entities/relations/triplets)
- Remove non-existent _result_cache imports
- Update documentation with both usage methods
Resolves pipx installation issue where semantica.mcp_server was not available.
Provides two ways to run: 'semantica-mcp' command or 'python -m semantica.mcp_server'.
- bug_001: top_k_per_entity now uses OR semantics — keep a candidate if
EITHER entity is under quota, preventing high-quality candidates being
silently dropped when a popular counterpart saturates its quota
- bug_002: validate max_results and top_k_per_entity at construction;
negative or non-int values raise ValueError instead of silent empty output
- bug_003: validate min_similarity in [0.0, 1.0] at construction;
out-of-range values raise ValueError
- bug_004: harden ConflictDetector method='relationship' normalization —
always produces List[Dict] before calling detect_relationship_conflicts
- quality_001: update detect_duplicates + incremental_detect docstrings to
reflect configurable sort_by field (not hardcoded 'confidence')
- quality_002: add _normalize_entity_id helper (always str) used in both
_apply_result_limits and _build_duplicate_groups for consistent ID handling
Backward compatible: callers not using new params see no behavior change.
58 tests pass (0 failures)
Fixes#534
- New __init__ params: max_results, top_k_per_entity, min_similarity, sort_by
- _apply_result_limits: drop below min_similarity, sort by sort_by field,
enforce top_k_per_entity per entity, cap at max_results globally
- Wired into detect_duplicates() and incremental_detect()
- 30 new tests in TestResultLimiting; full suite 42/42 passed
Fixes#533
- Removes duplicate `detect_conflicts` definition that was silently overridden,
causing AttributeError for callers passing `method=` or `property_name=` kwargs
- Merges dispatcher logic into the surviving method with `method="all"` default
supporting: "all", "value", "property", "type", "relationship", "temporal",
"logical", "entity"
- Fixes `method="relationship"` incorrectly defaulting `relationships` to the
entities list; now defaults to `[]` with dict normalization
- Removes unreachable dead code block after try/except raise in
`detect_entity_conflicts`
* fix(deps): remove gpu extra from [all] to fix Windows installation failure
faiss-gpu has no Windows builds, so semantica[all] failed with
'No matching distribution found for faiss-gpu>=1.7.0' on Windows.
Removed gpu from both [all] lines — semantica[gpu] remains available
as an explicit opt-in for Linux GPU environments.
Closes#532
* docs(changelog): record faiss-gpu Windows installation failure fix (#532)
Closes#531
- Replace 5 direct sys.stdout.write() calls in ConsoleProgressDisplay.update()
with self._safe_write() so emoji/block characters are encoded safely on
Windows cp1252 consoles
- Add TestProgressTrackerEncoding regression tests (3 cases) covering
_safe_write, pipeline header, and auto emoji-disable on cp1252
test_retry_logic.py injected sys.modules["openai"] = MagicMock() at module
level so providers.py could be imported without the real openai package.
Those mocks were never restored, leaving openai (and spacy, instructor etc.)
as MagicMock objects for the entire test session. This caused
test_pr482_deepseek_openai tests to receive a MagicMock when importing
openai.OpenAI, making MagicMock(spec=OpenAI) raise InvalidSpecError.
Fix: save original sys.modules entries before injection and restore them
immediately after the semantica imports that needed the mocks complete.
The mock objects remain bound inside the already-imported provider module,
so test_retry_logic tests are unaffected; other test modules now see the
real packages again.

subprocess.CompletedProcess[str] as a return annotation is not subscriptable
at runtime on Python 3.8, causing test collection to abort before any tests
run. Adding PEP 563 deferred evaluation makes all annotations strings at
import time, restoring 3.8 compatibility without changing behaviour on 3.9+.

* fix(ingest): lazy-load optional ingestion backends
* fix(ingest): address qodo review — use ModuleNotFoundError and guard ConfigurationError
Bug 1: Replace overbroad `except ImportError` with `except ModuleNotFoundError` in
__getattr__ (__init__.py) and all four optional-backend loaders (methods.py). This
prevents internal import errors inside a backend module from being silently rewritten
into a misleading "package not installed" message. Also simplifies _is_missing_dependency
to rely solely on exc.name now that ModuleNotFoundError always sets it.
Bug 2: Add `except ConfigurationError: raise` before the blanket `except Exception`
handlers in ingest_web, ingest_feed, ingest_repository, and ingest_email. Missing
optional dependencies are expected user-config issues and must not be logged as errors.

* fix(tests): set exc.name on blocker's ModuleNotFoundError to match Python import machinery
OptionalDependencyBlocker was constructing ModuleNotFoundError with only a
message string, leaving .name as None. _is_missing_dependency checks exc.name
directly (the string-scan fallback was removed when switching to
ModuleNotFoundError), so the ConfigurationError conversion never triggered and
the test asserted the wrong exception type.
Python's import machinery always sets .name to the top-level module name when
it raises ModuleNotFoundError; the blocker now does the same.

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

- Fix domain_uri/range_uri always being truthy strings
- Only create rdfs:domain/rdfs:range edges when domain/range are non-empty strings
- Add proper validation with .strip() to handle whitespace-only values
- Apply fix to both 'data' and 'text' mode ontology creation
- Prevents pollution of graph with invalid edges to namespace root
Fixes issue where empty domain/range values like '' or None would still create
edges pointing to namespace root (e.g., 'https://ex/#/') instead of being
properly omitted.
The pattern `<[^>]+>\s+<[^>]+>` in _detect_format() was flagged by CodeQL
(py/polynomial-redos, CWE-1333/730/400) as a polynomial regular expression
on uncontrolled user data.
The `<...>` branch was already unreachable — strings starting with '<' return
'xml' two lines above — but CodeQL does not track that control flow path.
Fix: replace the entire re.match() call with plain startswith / 'in' checks:
- N-Triples with URI subjects are already handled by the XML branch.
- Only blank-node-subject N-Triples (_:word <uri> ...) need detection here,
which is correctly expressed as startswith('_:') and ' <' in stripped.
- Removed the now-unused `import re`.
Closes security advisory #23.

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

- 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.

- 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

Merge blockers (ZohaibHassan16):
- fix: distance-matrix raises HTTP 503 when metric=semantic but no
similarity backend is available, instead of silently returning hop
distances labeled as semantic
- fix: distance-enriched export now requires node_subset (HTTP 422 if
omitted), preventing unbounded all-pairs O(n^2) export over full graph
- fix: DistanceExportRequest default include corrected from ["hops",
"distance_band"] to ["source_id", "target_id", "hop_count",
"distance_band"] so default exports are unambiguous and use the correct
column name
- fix: confidence decay edge weight index now reads graph_dict.get("edges")
or graph_dict.get("relationships") to handle both graph dict shapes,
fixing always-1.0 decay when session returns relationships key
Bot findings (github-code-quality / chatgpt-codex):
- fix: remove unused Iterable import from distance_exporter.py
- fix: remove unused Response import from graph.py
- fix: move logger init before optional KG import; replace empty
except ImportError: pass with logger.debug in distance_exporter.py
- fix: replace two bare except Exception: pass in temporal.distance_history
with logger.warning including source, target, metric, and timestamp context
- fix: remove mixed import style in test_qual003 — use only module import
and reference CausalChainAnalyzer through it
- 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.

Claude Code auto-loads hooks/hooks.json. Declaring it explicitly in
manifest.hooks causes: 'Duplicate hooks file detected ... already-loaded'.
Same pattern as agents: manifest should only reference *additional* hook
files beyond the default.
Two separate schema issues blocked `/plugin marketplace add ./plugins`
followed by `/plugin install semantica@semantica-local`:
1. `marketplace.json` was missing the required top-level `owner` object.
Claude Code rejects with: `owner: Invalid input: expected object,
received undefined`.
2. `plugin.json` declared `"agents": "./agents"` (string), but Claude
Code's manifest schema rejects non-array `agents` with:
`Validation errors: agents: Invalid input`. Auto-discovery from
the default `agents/` directory works when the field is omitted,
provided agents are flat `<name>.md` files with frontmatter (Claude
Code's subagent convention) rather than `<name>/AGENT.md`
subdirectories.
Changes:
- add `owner` object to `marketplace.json`
- drop `agents` field from `plugin.json` (falls back to auto-discovery)
- rename `agents/<name>/AGENT.md` -> `agents/<name>.md` (frontmatter
content is unchanged, just the path)
After this, the documented local-install flow succeeds end-to-end.
- Replace deepseek.Client with openai.OpenAI(base_url="https://api.deepseek.com/v1")
in DeepSeekProvider._init_client(); the deepseek PyPI package has no Client class
- Add self.base_url = "https://api.deepseek.com/v1" to DeepSeekProvider.__init__()
(missing from original PR; caused AttributeError on every instantiation)
- Fix verbose_mode NameError in BaseProvider.generate_typed() instructor path
- Update pyproject.toml: llm-deepseek extra now declares openai>=1.0.0
- Update _init_client warning message to reference openai library
- Add 19 tests in tests/semantic_extract/test_pr482_deepseek_openai.py
- Update CHANGELOG.md

- Replace list.sort() on every upsert with bisect.insort() — O(log n) per
insert instead of O(n log n); bulk rebuild still sorts once at the end
- Replace list.remove() in remove() with bisect.bisect_left + pop() — O(log n)
find instead of O(n) scan
- Wrap handle_graph_mutation() index mutations in self._lock — mutation bridge
fires from a background thread and was racing concurrent search/rebuild calls
- Drop source/target upserts in add_edge() — edges don't change node text so
the index documents are identical; removes unnecessary cache invalidation
- Sort tag values in _cache_key() — ["a","b"] and ["b","a"] now share a cache
entry since _passes_filters() uses set intersection (order-independent)
- Restore @app.get("/") root handler missing from this branch vs main

- Add _ttl_block() helper to accumulate all predicate-object pairs before
writing, producing a single valid Turtle subject block terminated by one
period — eliminates the bug where rdfs:subClassOf / domain / range were
appended after a closed '.' block
- Add missing data_properties loop to _export_owl_turtle so
owl:DatatypeProperty declarations are no longer silently dropped
- Add _escape_ttl_str() to escape quotes, backslashes, newlines, carriage
returns, and tabs inside Turtle string literals (rdfs:label, rdfs:comment,
owl:versionInfo)
- Unify optional-field null checks to consistent x = prop.get(); if x: pattern
- Add 43 tests in tests/export/test_owl_exporter.py covering syntax validity,
data properties, string escaping, null handling, and header output
- Update CHANGELOG.md with [Unreleased] entry
Closes#478

- 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].

- Add semantica/kg/knowledge_graph.py with KnowledgeGraph dataclass
(entities, relationships, metadata) plus __len__ and __bool__ helpers
- Export KnowledgeGraph from semantica/kg/__init__.py
- Add KGVisualizer._convert_knowledge_graph() for explicit, non-mutating
conversion from KnowledgeGraph to internal dict format
- Route isinstance(graph, KnowledgeGraph) through _convert_knowledge_graph
inside _normalize_graph so all five visualize_* entry points accept
KnowledgeGraph directly without any manual conversion
- Add TestFormalKnowledgeGraphType (15 tests)
Closes#471
- 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.

KGVisualizer.visualize_network() (and sibling methods) only accepted a raw
dict. Passing a KnowledgeGraph object — the natural output of
GraphBuilder.build() — silently returned without rendering.
Added _normalize_graph() which duck-types the input: dicts pass through
unchanged; any object exposing .entities / .relationships attributes is
converted to the canonical dict form; anything else raises a clear
ProcessingError naming the offending type.
_normalize_graph() is called as the first statement in visualize_network(),
visualize_communities(), visualize_centrality(), visualize_entity_types(),
and visualize_relationship_matrix().
Also adds 21 tests in tests/visualization/test_kg_visualizer_normalize_graph.py
covering the helper directly, the end-to-end regression for #458, and
a guard that every public method routes through _normalize_graph.

Tools grid:
- Claude Code/Cursor/Codex: 'Native plugin' (plugins/ dirs exist in repo)
- All other tools: 'REST API' (no MCP server impl in codebase — Semantica
has an MCP CLIENT for ingesting from MCP servers, not an MCP server)
- Codex CLI added back (has real plugin bundle at plugins/.codex-plugin/)
Plugin Bundles section:
- Full table of all 17 skills with descriptions matching SKILL.md files
- Full table of all 3 agents (kg-assistant, decision-advisor, explainability)
- Hooks entry referencing plugins/hooks/hooks.json
MCP Client section:
- Correct framing: MCPClient in semantica/ingest/mcp_client.py pulls
data FROM MCP servers into KG (not an MCP server itself)
- Code snippet + supported schemes
REST API Server section:
- Lists all 10 route modules from semantica/explorer/routes/ with paths
- WebSocket /ws endpoint
- Health check
Agno integration section:
- Expanded to table showing all 5 actual files in integrations/agno/
with class names and descriptions matching source code
AI Coding Tools table:
- Corrected connection types and setup notes to match actual code
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

- New '🖥️ Semantica Knowledge Explorer' section placed after Plugins,
with a workspace-tab table (Graph, Timeline, Decisions, Registry,
Entity Resolution, KG Overview, Ontology), a 4-line quick-start
snippet, requirements line, and a pointer to explorer/README.md
- Added explorer/ row to the detailed Modules table with a link
- Added explorer/ bullet to the condensed Modules list

- 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

fixes, and CodeQL infrastructure changes under [Unreleased] following
the existing Keep a Changelog format.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
fix(agent_memory): implement MemoryItem.to_dict() / from_dict() for safe JSON
persistence — timestamps serialised via isoformat(), embeddings dropped (not
JSON-safe, regenerated on demand); save() and load() now round-trip correctly
without TypeError or AttributeError (Bug #1)
fix(sparql): add asyncio.Semaphore(_SPARQL_MAX_CONCURRENT=4) around graph.query
so timed-out threads cannot exhaust the default ThreadPoolExecutor; add
`truncated: bool` field to SparqlResponse so callers know when the 5 000-row
cap was hit (Bug #2)
fix(export_import): trim _ALLOWED_IMPORT_EXTENSIONS to {.json, .csv} — the only
formats the handler actually parses; removes .graphml/.gexf/.ttl/.rdf that
passed the allowlist check but hit a hard 422 inside the handler (Bug #3)
fix(codeql): remove blanket rule-ID auto-dismiss job; replace with a commented
template for pinning specific alert numbers — prevents future real alerts of
the same rule being silently suppressed (Bug #4)

Bug 1 — non-string IDs crash store():
_resolve_iri() called .startswith() directly on local, causing AttributeError
when upstream graph builders emit integer entity/relationship IDs. Fixed by
coercing local to str() at entry; None/empty returns a safe urn: sentinel.
Bug 2 — prefixed W3C terms mis-resolved under base_uri:
Values like 'owl:Thing' and 'xsd:date' were not recognised as absolute IRIs
and with base_uri set were rewritten to e.g. https://example.com/owl:Thing,
corrupting standard OWL/XSD IRIs in stored triples. Fixed by adding a known-
prefix expansion table (xsd/rdf/rdfs/owl/skos/semantica) that is checked before
base_uri is applied, matching the same prefix map already used in blazegraph_store.
Added 5 regression tests covering both bugs: integer IDs with/without base_uri,
owl:Thing domain/range, xsd:date range, and rdfs:/skos: parent class expansion.
store() was minting urn:entity:, urn:class:, and urn:property: URIs for every
bare local name, even when the ontology carried a namespace.base_uri. This made
instance data and ontology class data irreconcilable in SPARQL joins.
- Extract base_uri from ontology.namespace.base_uri (or ontology.uri as fallback)
- Introduce _resolve_iri(local, kind) closure that appends the local name to
base_uri when present, keeping urn: fallback only when no base URI is known
- Apply _resolve_iri consistently for entity URIs, entity types, relationship
predicates, ontology class URIs, parent class URIs, property URIs, and
property domain/range URIs
- Explicit entity.uri values are never overridden
- Added 9 regression tests in TestTripletStoreOntologyNamespace covering all
IRI expansion paths, urn: fallback, explicit URI passthrough, top-level uri
key fallback, and trailing-slash safety
- Added _resolve_datatype_iri() to expand known prefixes (xsd/rdf/rdfs/owl/skos)
to full IRIs instead of blindly wrapping in <...>, fixing invalid SPARQL like
<xsd:integer>
- Validated language tags against RFC 5646 regex to prevent SPARQL injection
via metadata["lang"] values containing whitespace or punctuation
- Validated datatype IRIs for whitespace/special characters before interpolation
- Extended test suite from 7 to 15 cases covering prefix expansion, injection
rejection, and all accepted input forms
- Bug 1: replace dict .get() with dataclass attribute access on
AssociativeClass (name/connects/temporal/properties)
- Bug 2: add full URI to every ontology property and use BASE_URI-prefixed
URIs for all relationship types so TripletStore stores hr:<name>
instead of urn:property:<name>, fixing SPARQL PREFIX hr: queries
- Bug 3: filter None values from EmploymentEvent properties dict so
open-ended employment does not store the literal string "None" as endDate
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Audited every module's __init__.py and source files. Fixes:
1. Temporal GraphRAG example — was garbled (two sections merged into one
code block). Restored clean single example with correct imports.
2. Semantic extraction — extract_entities/extract_relations/extract_triplets
are not standalone functions; replaced with correct class-based API:
NERExtractor().extract_entities(), RelationExtractor().extract_relations(),
TripletExtractor().extract_triplets(). extract_relations_llm is only in
semantica.semantic_extract.methods (not re-exported from __init__) and
requires entities as its required second positional arg — fixed both.
3. ReteEngine — add_rule() and match() do not exist on ReteEngine.
Replaced with correct API: Rule/Fact dataclasses + build_network([rule])
+ add_fact(fact) + match_patterns().
4. PipelineBuilder — add_stage(name, callable) does not exist; replaced
with add_step(name, type_str, **config). with_parallel_workers() does not
exist; replaced with set_parallelism(n). Pipeline.run() takes no
input_path; removed that kwarg.
5. ProvenanceTracker.track_entity — source_url is not a valid kwarg;
second param is positional source. Fixed in features list and comment.
6. Leftover SHACL section — removed second copy of the SHACL code block
that still referenced to_shacl(), export_shacl(), validate_graph() which
do not exist on OntologyEngine (confirmed in engine.py).
7. Duplicate pip install lines — semantica[shacl] and semantica[db-snowflake]
appeared twice in the installation block; removed duplicates.

Bug 1 — Broken snapshot example:
- Replace graph.add_decision(category=...) with graph.record_decision()
which accepts keyword args (add_decision expects a Decision object)
- Define context = AgentContext(...) before calling context.checkpoint()
and context.diff_checkpoints() — these APIs live on AgentContext, not ContextGraph
Bug 2 — Invalid KG example imports:
- Remove KnowledgeGraph, Entity, Relationship, CentralityAnalyzer — not exported
- Replace with GraphBuilder.build() (dict-based API) and CentralityCalculator
which are the actual public exports from semantica.kg
- Fix pipeline example: KnowledgeGraph() → GraphBuilder()
Bug 3 — Nonexistent SHACL APIs:
- Remove export_shacl() and validate_graph() calls — not on OntologyEngine
- Rewrite SHACL section to use real APIs: from_data(), export_owl(),
validate(), from_text(), to_owl()
- Remove semantica[shacl] install instructions (extra not in pyproject.toml)
Bug 4 — Stale docs version badge:
- docs/index.md: bump version badge and release tag link from v0.3.0 → v0.4.0
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Replace dense tables with scannable bullet points throughout
- Add plain-English descriptions before each feature section
- Update What's New to cover full v0.4.0 temporal stack, SKOS, SHACL, and fixes
- Add learn-more references linking to docs and cookbook per section
- Slim code examples to focused real-world scenarios, remove API-dump patterns

This commit transforms the raw 150k-element graph into a high-performance, exploratory UI:
- Implemented Universal Sizing (logarithmic scale based on node degree) and a Procedural Color Mapper (string hashing) to automatically size and colorize categorical data.
- Built the 'Focus Mode' engine using Sigma reducers. Hovering or clicking a node instantly isolates it and its 1-hop neighbors while muting the canvas, eliminating visual noise.
- Applied an enterprise-grade visual style, featuring deep radial background gradients, structural grid overlays, and a sliding glassmorphism metadata HUD.
- Shifted from DOM-bound state mutations to direct WebGL render pipelines to maintain visual performance.
- add_decision: pass valid_from/valid_until through kwargs path so
temporal bounds are not silently dropped into metadata (Codex P1)
- add_decision: raise ValueError when Decision object and kwargs are
both provided, instead of silently ignoring the kwargs (Codex P2)
- fix guard condition to exclude decision_maker (non-None default)
to avoid false-positive ValueError on plain add_decision(obj) calls
- test_395: remove unused `import time`; strengthen as_of test with
concrete assertions on scenarios list (github-code-quality)
- test_unreleased: remove unused `import time`; drop unused `snap =`
assignment; drop unused `provider =` assignment (github-code-quality)

- test_add_decision_kwargs_form: verifies add_decision() accepts kwargs
directly (category, scenario, reasoning, outcome, confidence) without
requiring a Decision object
- test_add_decision_kwargs_and_object_both_return_id: verifies both call
forms return a non-empty string ID
- test_agent_context_inmemory_store_and_retrieve: verifies AgentContext
with VectorStore(backend="inmemory") stores memories without faiss-cpu
Closes#433
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Fixes#433
- ContextGraph.add_decision() now accepts keyword arguments (category,
scenario, reasoning, outcome, confidence, entities, decision_maker)
in addition to a Decision object, matching documented behaviour.
Both call forms return the decision ID string.
- Quickstart snippets in README, getting-started.md, and index.md
changed from VectorStore(backend="faiss") to VectorStore(backend="inmemory")
so they work without faiss-cpu installed.
- docs/reference/context.md methods table updated to reflect the dual
signature of add_decision().
- docs/bugs/quickstart_api_mismatch.md added to track the issue.

GITHUB_TOKEN cannot change Default Setup (requires admin rights — HTTP 403).
Removed the disable-default-setup job entirely.
New approach:
- analyze job: runs CodeQL with upload:false then uploads SARIF via
upload-sarif with continue-on-error:true so the workflow does not fail
if Default Setup is still active
- dismiss-fixed-alerts job: runs on push to main, fetches all open alerts
matching the 3 fixed rule IDs and dismisses them via PATCH API which
only requires security-events:write (no admin needed)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The previous fix used || true in a single-step which masked API failures
and had no propagation delay — Default Setup remained active when the
SARIF upload ran, causing the same conflict error.
Changes:
- New job `disable-default-setup` runs first: calls the API, waits 30s,
then polls to confirm state=not-configured before exiting
- `analyze` job depends on `disable-default-setup` via `needs:` so CodeQL
only runs after the state change is confirmed propagated
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Advanced Setup and Default Setup cannot run simultaneously — SARIF upload
fails with "cannot be processed when the default setup is enabled".
Added a pre-analysis step that calls the GitHub code-scanning API to switch
Default Setup to not-configured before CodeQL runs, eliminating the conflict.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds explicit CodeQL analysis workflow triggered on push/PR to main and
weekly schedule. Without this, GitHub Default Setup only runs on a
schedule — alerts do not re-scan after a PR merge, leaving fixed
vulnerabilities still shown as open.

- 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)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- server.py: split vocabulary router into its own try/except so a missing
vocabulary module (pending #421) cannot prevent the 7 existing routers
from mounting
- rdf_parser.py: rename `format` param to `rdf_format` to avoid shadowing
the Python builtin; add exception chaining (raise...from e); document
the silent edge-drop behaviour for cross-vocabulary URIs
- Add semantica/explorer/utils/__init__.py (package was not importable)
- Add tests/explorer/test_rdf_parser.py: 32 tests covering node/edge
extraction, label priority, altLabel dedup, all 6 SKOS edge types,
orphan-edge filtering, empty graph, error cases, and RDF/XML format
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Extends the existing ontology and triplet-store stack with first-class
SKOS support without adding any new top-level packages.
### semantica/ontology/namespace_manager.py
- `get_skos_uri(local_name)` — build full skos:core# URI from local name
- `build_concept_scheme_uri(name)` — slug a human name into a stable
ConceptScheme URI anchored at the configured base URI
### semantica/triplet_store/triplet_store.py
- `add_skos_concept(concept_uri, scheme_uri, pref_label, ...)` — asserts
ConceptScheme + Concept triples, prefLabel, altLabel, broader, narrower,
related, definition, notation via existing `add_triplets()` API
- `get_skos_concepts(scheme_uri=None)` — SPARQL SELECT via `execute_query()`,
collapses multi-valued bindings into concept dicts
### semantica/ontology/engine.py
- `list_vocabularies()` — list all skos:ConceptScheme instances
- `list_concepts(scheme_uri)` — list concepts in a scheme with alt labels
- `search_concepts(query, scheme_uri=None)` — case-insensitive substring
search over prefLabel + altLabel; sanitises user input against SPARQL injection
### tests

- Add TemporalGraphRetriever to context_retriever.py (no new file per project convention)
- Drop-in wrapper for ContextRetriever; filters related_entities/related_relationships
via reconstruct_at_time(); at_time=None is a true passthrough
- Returns new RetrievedContext objects (no in-place mutation)
- Graceful ImportError if temporal modules unavailable
- Add at_time + header_template to ContextRetriever._generate_reasoned_response()
and query_with_reasoning()
- Temporal header prepended to LLM context block only when at_time is set
- Naive datetimes normalised to UTC before formatting
- Header built with str.replace (not .format) to prevent format-string injection
- Add TemporalQueryRewriter + TemporalQueryResult to semantica/kg/
- Regex-only (default) and LLM-assisted extraction modes
- Resolves temporal phrases via TemporalNormalizer (deterministic, zero LLM)
- Word-boundary guards on intent keywords; year fallback for noun-phrase dates
- Never calls reconstruct_at_time — extraction only
- Export TemporalGraphRetriever from semantica.context
- Export TemporalQueryRewriter, TemporalQueryResult from semantica.kg
- Add 99 tests across two new test files
- tests/context/test_temporal_retriever.py (56 tests)
- tests/kg/test_temporal_query_rewriter.py (43 tests)

- Add `extract_temporal_bounds: bool = False` to `extract_relations_llm()`.
When True the LLM prompt is extended with a calibrated confidence scale
and four few-shot examples; each returned Relation gains valid_from,
valid_until, temporal_confidence, and temporal_source_text in metadata.
Low confidence (<0.5) with non-null dates logs a WARNING. Default False
preserves 100% backward compatibility.
- Add `RelationWithTemporalOut` / `RelationsWithTemporalResponse` Pydantic
schemas so the four temporal fields are captured from structured LLM
output (separate from RelationOut which uses extra="ignore").
- New `semantica/kg/temporal_normalizer.py` — `TemporalNormalizer` class
(zero LLM calls, pure regex + dateutil arithmetic):
* normalize(value) → (start, end) UTC datetimes or None
* Resolution order: ISO 8601 → partial dates (year/month/Q) →
ambiguity detection → domain phrase map → relative phrases
* normalize_phrase(phrase) → metadata dict or None
* Default phrase map covers 13 domains: General, Policy, Healthcare,
Drug Discovery, Cybersecurity, Supply Chain, Finance, Energy
* TemporalAmbiguityWarning for DD/MM/YYYY-style ambiguous inputs
* Custom phrase_map at construction (merged over defaults)
- Add `TemporalAmbiguityWarning(UserWarning)` to exceptions.py.
- Export `TemporalNormalizer` from `semantica/kg/__init__.py`.
- Propagate `extract_temporal_bounds` through `_extract_relations_chunked`
and add flag to cache key to prevent cross-mode cache pollution.
- 53 new tests in tests/semantic_extract/test_temporal_extraction.py;
zero real LLM calls, suite runs in ~3.5s. 873 existing tests unaffected.

Closes#408
Previously `_init_client` assigned the raw `ollama` module to
`self.client`, so the `base_url` parameter was silently ignored and
every request hit the default localhost:11434. Now an `ollama.Client`
instance is created with `host=self.base_url`, so remote Ollama servers
are reachable.
Three regression tests added to prevent recurrence:
- default base_url is forwarded as host
- custom base_url (e.g. http://192.168.1.3:11434) is forwarded as host
- self.client is never the raw module

Documents both @ZohaibHassan16's original fallback implementation and
the follow-up fixes by @KaifAhmad1: isinstance regression, add_node
signature bug, add_edge spurious kwarg, timezone handling, BFS
find_edges hoist, duplicate import removal, and full test coverage.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Replace isinstance(graph_store, ContextGraph) with type() is ContextGraph
in all 12 guards across decision_query.py and decision_recorder.py.
Fixes 2 regressions where Mock(spec=ContextGraph) triggered fallback
paths, causing TypeError on iteration of mock return values.
- Hoist find_edges() calls out of the BFS while-loop in trace_decision_path
so edges are fetched once per call instead of once per visited node,
eliminating O(nodes * total_edges) repeated full-graph fetches.
- Expand test_decision_query_fallback.py: keep the original integration
test and add 13 targeted unit tests covering all 7 DecisionQuery and
4 DecisionRecorder ContextGraph fallback methods, including tz-aware/naive
datetime mixing and Mock guard validation.
Result: 353 passed, 0 failed (was 338 passed, 2 failed on this branch)

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.

- session.search(): normalise node.to_dict() "properties" envelope to flat
{id, type, content, metadata} so /api/graph/search returns populated content
and properties instead of empty strings (Qodo bug #3)
- context_graph.add_edges(): fall back to "metadata" key when "properties" is
absent so edges imported from find_edges()/build_graph_dict() format don't
silently lose their metadata (Qodo bug #2)
- enrich.predict_links(): wrap the O(n) scoring loop in asyncio.to_thread() so
it never blocks the event loop on large graphs (Qodo bug #1)
- session.py: remove duplicate __init__ annotations assignment, duplicate
property definitions (un-locked first set), and dead-code double-query
inside get_nodes()/get_edges() left over from the merge
- enrich.py: remove unreachable code block after early return in predict_links
and duplicate nodes fetch in detect_duplicates left over from the merge
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
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.

Package & distribution
- pyproject.toml: add integrations* to packages.find include so pip
install semantica[agno] ships the integration
context_store.py
- upsert_memory(): run NERExtractor after store() to index entities
into the ContextGraph
- delete_memory() / drop_table() / clear(): call AgentContext.forget()
to propagate deletions to vector/graph storage
- find_precedents(): pass limit parameter to find_precedents_advanced()
- retrieve(): pass limit as max_results to AgentContext.retrieve()
- add get_context_for_prompt() for automatic system-prompt injection
knowledge_graph.py
- __init__: wire graph_builder.graph_store = self._graph so build()
persists into the ContextGraph
- add internal AgentContext for vector retrieval (shared ContextGraph)
- search(): use AgentContext.retrieve() for vector similarity; keyword
scoring as fallback
- _ingest_text(): add paragraph-level chunking before NER/relation
extraction (parse → split → NER → relation extract → graph build)
- get_graph_context(): return structured subgraph with edge types via
ContextGraph.get_neighbors()
- load_urls(): validate scheme (http/https only) to prevent SSRF
decision_kit.py
- check_policy(): replace broken PolicyEngine.check_compliance() call
with inline _eval_rule() that evaluates simple field-op-value rules;
return compliant=False (not True) on failure — closes security bug
kg_toolkit.py
- add_to_graph(): fix add_node(node_id=, node_type=) and
add_edge(source_id=, target_id=, edge_type=) to match real API
- query_graph(): use find_nodes() (no label param) + keyword filter
- find_related(): use get_neighbors(node_id=) returning List[Dict]
- infer_facts() / export_subgraph(): use find_nodes() public API
instead of private _nodes dict
shared_context.py
- _AgentScopedStore: store shared context as self._context (not
self._ctx) so all inherited AgnoContextStore methods work correctly
tests/integrations/agno/test_kg_toolkit.py
- _FakeGraph: rewrite to match real ContextGraph signatures —
find_nodes(node_type=), add_node(node_id, node_type, **),
add_edge(source_id, target_id, edge_type, **),
get_neighbors(node_id, hops=1, ...) returning List[Dict]

markdown; '**/*.md' covers all subdirectories (cookbook/, docs/, etc.)
- Add cache: 'pip' to setup-python in ci.yml to avoid re-downloading
heavy packages (torch, spacy, faiss) on every run
- Update security-scan PR comment text to accurately reflect that it
skips doc/markdown-only PRs, not "every PR"

When centrality_calculator falls back to basic implementation on a mocked
networkx call, measure_data['centrality'].get() can return a MagicMock.
MagicMock silently supports __mul__ and __add__, so the arithmetic on
influence_score produces a MagicMock instead of raising, causing the
isinstance(influence_score, (int, float)) assertion to fail in tests.
Guard each centrality value with isinstance(val, (int, float)) and default
to 0.0 for any non-numeric value before storing it.

- fix(query_engine): progress tracker leak in expand_entity_uri
stop_tracking was only called inside the `if hasattr(execute_sparql)`
block; backends without execute_sparql silently leaked a tracker entry.
Now stop_tracking(completed) is always reached on the happy path, and
stop_tracking(failed) is reached on exception.
- fix(query_engine): add skos:relatedMatch to expand_entity_uri FILTER
get_alignment_predicates() exposed relatedMatch but the SPARQL filter
did not include it, making relatedMatch alignments invisible.
- fix(query_engine): sanitize URIs in build_values_clause
URIs were interpolated raw into <{uri}> angle-bracket literals.
A URI containing > would break the VALUES clause. Now _sanitize_uri
is applied to every URI before wrapping.
- fix(engine): add skos:relatedMatch to get_alignments and list_alignments
FILTER lists now consistent with get_alignment_predicates().
- fix(engine): close SPARQL injection vector in list_alignments
Previously only " was escaped in the ontology_uri filter string.
A URI containing } would break out of the WHERE block. Now \, ", {
and } are all percent-encoded before interpolation.
- fix(engine): validate predicate is a full URI in create_alignment
Passing a CURIE like "owl:equivalentClass" silently stored a broken
triple that get_alignments() could never find. Now raises ProcessingError
with a clear message if the predicate does not start with http/https.
- fix(tests): rewrite E2E test to actually be end-to-end
test_end_to_end_cross_ontology_uri_flow was mocking expand_entity_uri
itself, so it only tested build_values_clause string formatting.
Now uses a real mock backend with execute_sparql, calls the real
expand_entity_uri, and asserts both the backend was queried and the
resulting SPARQL template contains both URIs.

* fix: make cross-graph links durable across save/load
The previous fix prevented phantom 'entity' node pollution but left

Changes:
- Add graph_id (UUID) to ContextGraph so instances are identifiable
- save_to_file() now writes a 'links' section with link_id,
source_node_id, target_node_id, and other_graph_id
- load_from_file() restores graph_id and populates _unresolved_links
- navigate_to() raises a clear KeyError with resolve_links() hint when
a link exists but hasn't been reconnected yet
- New resolve_links(registry) method reconnects links post-load given
a {graph_id: ContextGraph} mapping; returns resolved count
- Add 14 tests in tests/context/test_cross_graph_navigation.py covering
link creation, phantom-node prevention, and full save/load round-trips

- rdf_exporter.py: add isinstance(format, str) guard before .lower() so
non-string inputs (None, int, etc.) raise ValidationError consistently
instead of AttributeError; normalize via strip().lower() in one step
- 15_Export.ipynb: fix notebook cell using result['valid'] → result['overall_valid']
(validate_rdf() returns overall_valid, not valid); add trailing EOF newline
- test_rdf_exporter.py: add tests for non-string format → ValidationError
and for overall_valid key presence in validate_rdf() return value

Bug 1 — _parse_relation_result (methods.py):
Relations whose subject/object weren't in the pre-extracted NER list were
silently dropped because match_entity() returned None and the old code
gated on `if subject_entity and object_entity`. Now unmatched names
produce a synthetic UNKNOWN Entity so every LLM-returned relation is
preserved (all three Apple co-founders are now returned).
Bug 2 — _match_pattern (reasoner.py):
Rewrote the regex builder to split on ?var placeholders first, then
apply re.escape() only to the surrounding literal segments. The old
approach (escape-then-sub) left edge cases where pre-bound variables
and multi-word values with spaces could fail to unify. The new
implementation also handles repeated variables via backreferences and
uses non-greedy .+? to avoid over-consuming literal separators.
Closes#354

Evict semantica.graph_store.age_store from sys.modules before importing
it with the mocked psycopg2, so the mock takes effect even when other
tests have already loaded the semantica package (and cached age_store
with its original psycopg2 binding).

Follow-up commit for PR #292
allocate_resources() acquires self.lock and then calls allocate_cpu(),
allocate_memory(), and allocate_gpu(), each of which also acquire
self.lock. With a non-reentrant threading.Lock this causes a deadlock
whenever build_knowledge_base() triggers the pipeline resource
allocation path.
Switch to threading.RLock() so the same thread can re-enter the lock.

- Added complete documentation (usage guide and API reference)
- Zero breaking changes - fully backward compatible
Models like gpt-5-mini only support specific temperature values.
This change allows temperature=None to mean "use model's default"
by omitting the parameter from API calls entirely.
Changes:
- Add _add_if_set helper to BaseProvider for cleaner param handling
- Update all providers to conditionally include temperature
- Remove hardcoded temperature defaults from entry points
- Keep 0.7 default for HuggingFace (local models)
- Keep 0.1 fallback for generate_typed (structured output)

# Semantica
This Skill helps Claude apply Semantica knowledge graph capabilities to context graph analysis, decision intelligence, explainability, semantic extraction, graph analytics, reasoning, provenance, ontology, policy, ingestion, deduplication, and export.
## When to use this Skill
- The user asks about knowledge graphs, entities, relations, triplets, or semantic extraction.
- A task requires context graph analysis, graph topology, centrality, communities, paths, or embeddings.
- The request involves decision intelligence, causal influence, decision graphs, or outcome analysis.
- The user asks for explainability, decision rationale, or transparency for graph results.
- The request involves reasoning: deductive, abductive, SPARQL, Datalog, or Rete rules.
- The user needs provenance, audit history, lineage tracking, or change tracing.
- The request is about ontology modeling, schema validation, or policy enforcement.
- Data must be ingested from files, databases, APIs, repositories, or MCP servers.
- There is a need to deduplicate entities, normalize graph data, or merge duplicate graph objects.
- The user wants to export graphs to JSON, RDF, Parquet, CSV, GraphML, or similar.
## What this Skill contains
- Semantic extraction guidance for NER, relation extraction, event detection, coreference resolution, and triplet generation.
- Context graph and graph analytics workflows for topology, centrality, community detection, path finding, embeddings, and decision insights.
- Decision intelligence support for causal reasoning, decision impact, decision graphs, and outcome analysis.
- Explainability guidance for decision rationale, graph reasoning, rule traces, and result transparency.
- Reasoning support for logic, hypotheses, SPARQL, Datalog, and rule-based inference.
- Provenance and audit guidance for tracing sources, recording changes, and verifying graph lineage.
- Ontology guidance for defining concepts, validating schemas, and modeling relationships.
- Policy checks for compliance evaluation and graph governance.
- Temporal analysis guidance for event timelines and graph evolution.
- Deduplication support for duplicate detection, fuzzy matching, and graph cleanup.
- Export workflows for sharing results in multiple structured formats.
## Best prompt patterns
Use clear task descriptions, and mention the desired output format when possible.
- "Extract entities, relations, and events from this text and summarize the resulting graph."
- "Analyze this context graph and show the top 5 most influential nodes."
- "Generate a decision intelligence report with causal impact and explainability."
- "Run a provenance trace for node X and describe its history."
- "Validate the ontology for this graph and report any schema problems."
- "Ingest the data from this MCP server and merge it into the current graph."
- "Export the graph to JSON and GraphML with node and edge metadata."
## How Claude should use this Skill
1. Read the YAML metadata and identify whether the request matches Semantica graph, context graph, decision intelligence, or extraction tasks.
2. Load this Skill when the request mentions Semantica, knowledge graphs, context graphs, decision intelligence, explainability, reasoning, or provenance.
3. Use the instructions here to choose the right workflow and then read additional files or scripts only if needed.
## Authoring note
This Skill is purposely concise and focused on task selection. It is not intended to include every detail; Claude should use the filesystem-based model to load any extra reference files only when asked.

-Create/edit/delete alignments with source URI, target URI, relation selector (owl:equivalentClass, all five skos:*Match variants), confidence slider, provenance, and reviewer fields.
-Pairwise alignment matrix: scrollable table for all loaded ontology pairs; clicking a badge pre-fills the form.
- **Entity Search panel** (PR #518) — debounced 320 ms search across all loaded ontologies; type filter pills; result detail panel with super/subclasses, domain/range, instance count.
- **Graph Workspace declutter** (PR #483, @ZohaibHassan16) — calmer default presentation for dense graphs, display-edge aggregation with raw-edge bundle retention, grouped community view, neighborhood collapse/expand.
- **Bidirectional path finding** (closes #469, @KaifAhmad1) — `directed=false` query param on BFS and Dijkstra; undirected view built via `graph.to_undirected()` for traversal only; empty-path 404 guard; `PathResponse.directed` field.
- **Node distance semantics in path responses** (closes #472) — `PathResponse` gains `hop_count` and `distance_band` ("direct"/"near"/"mid-range"/"distant"); `classify_path_distance()` in `semantica/utils/helpers.py`; `KGVisualizer.visualize_network(highlight_path)` with band-scaled edge rendering.
- **Native `KnowledgeGraph` type support in `KGVisualizer`** (closes #471) — formal `KnowledgeGraph` dataclass (`entities`, `relationships`, `metadata`); `_normalize_graph()` routes it through `_convert_knowledge_graph()` as an explicit fast-path in all 5 `visualize_*` methods.
- **Indexed search for large graphs** (PR #481, @ZohaibHassan16) — purpose-built inverted index with exact/token/prefix lookup tiers; LRU cache (128 slots); O(log n) mutation sync via `bisect.insort`; warm-query time 24 ms → 0.004 ms on 118 k-node graph.
- **Provenance traversal multi-hop fix** (PR #480, @Sameer6305) — undirected ego-graph expansion so upstream ancestors at depth ≥ 2 are no longer silently excluded; `ProvenanceEdge.direction` field (upstream/downstream/lateral); grouped markdown report under `## Upstream/Downstream/Lateral` sections.
- **TripletStore ontology namespace** (PR #447, @KaifAhmad1) — `_resolve_iri()` applies `base_uri` before `urn:` fallback; W3C prefix expansion table (owl/xsd/rdf/rdfs/skos) expands to canonical IRIs regardless of `base_uri`.
- **DeepSeek provider via OpenAI SDK** (PR #482, @liling) — `_init_client` rewritten using `openai.OpenAI(base_url=self.base_url)` instead of defunct `deepseek` package; `verbose_mode` assignment fix; `pyproject.toml` updated to `openai>=1.0.0`.
- Tests: Comprehensive units for TextNormalizer (PR #242 by @ZohaibHassan16)
- Added focused test coverage for TextNormalizer behavior across inputs
### Added
-Tests: Register integration mark and tidy ingest test warnings (PR #241 by @KaifAhmad1)
-Introduced integration test marker and reduced noisy warnings in ingest tests
-**`DuplicateDetector` result limiting and ranking** (issue #534, by @KaifAhmad1):
-`max_results` — hard global cap on returned candidates; applied after sorting. `None` means no limit.
-`top_k_per_entity` — keep at most *k* candidates per entity (by the sort field) so no single entity floods the output. `None` means no per-entity limit.
-`min_similarity` — extra similarity floor on top of `similarity_threshold`; candidates below it are dropped before ranking. `None` means no extra floor.
-`sort_by` — ranking field before limits are applied; accepts `"confidence"` (default) or `"similarity_score"`. Invalid values raise `ValueError` at construction time.
- All four options are applied by the new `_apply_result_limits` helper and are respected by both `detect_duplicates()` and `incremental_detect()`.
- 15 new tests in `TestResultLimiting` covering each option in isolation and in combination.
-`top_k_per_entity` now uses OR semantics — a candidate is kept if *either* entity is still under quota, preventing high-quality pairs from being silently dropped when a popular counterpart saturates its limit.
-`max_results` and `top_k_per_entity` now validated at construction time; negative or non-integer values raise `ValueError`.
-`min_similarity` now validated in `[0.0, 1.0]` at construction; out-of-range values raise `ValueError`.
- Added `_normalize_entity_id` helper (always returns `str`) used consistently in both `_apply_result_limits` and `_build_duplicate_groups`, eliminating `int` vs `str` ID key mismatches.
- Updated `detect_duplicates` and `incremental_detect` docstrings to reflect the configurable `sort_by` field.
- Tests (ingest): Add unit tests for file, web, and feed ingestors (PR #239 by @Mohammed2372)
- Broadened ingest test coverage across multiple source types
### Fixed
- **Fix: `ConflictDetector.detect_conflicts()` raises `AttributeError` when called with `method=` or `property_name=` kwargs** (issue #533, PR conflicts, by @KaifAhmad1):
-`detect_conflicts` was defined twice in `conflict_detector.py`; Python silently overwrote the first (dispatcher) definition with the second (comprehensive), which accepted no `method` or `property_name` parameters — causing `AttributeError` or `TypeError` for any caller using those kwargs.
- Removed the first (dead) definition and merged its dispatcher logic into the surviving method. New signature: `detect_conflicts(entities, method="all", property_name=None, entity_type=None, **kwargs)`.
- Fixed `method="relationship"` silently defaulting `relationships` to the entities list, which caused entity dicts to be iterated as relationship dicts producing silent wrong results (`None_None_None` keys). Now defaults to `[]` with dict normalization.
- Removed unreachable dead code (`for field_name in fields_to_check` loop after `try/except raise`) in `detect_entity_conflicts`.
- **Follow-up Qodo review fix** — hardened `method="relationship"` normalization: when `relationships` kwarg is a dict whose `"relationships"` value is itself a non-list (or the key is absent), the value is now always wrapped in a list before being passed to `detect_relationship_conflicts`, guaranteeing `List[Dict]` input in all cases.
- **Fix: `semantica[all]` installation fails on Windows due to `faiss-gpu` dependency** (issue #532, PR #utlis, by @KaifAhmad1):
-`[all]` bundled the `[gpu]` extra (`faiss-gpu>=1.7.0`, `cupy>=10.0.0`), which has no Windows builds, causing `pip install "semantica[all]"` to fail with `No matching distribution found for faiss-gpu>=1.7.0`.
- Removed `gpu` from both `[all]` lines in `pyproject.toml` — `[all]` now installs only cross-platform dependencies. Users on Linux who need GPU acceleration can install `semantica[gpu]` explicitly.
- **Fix: Progress tracker crashes with `UnicodeEncodeError` on Windows cp1252 consoles** (issue #531, PR #utlis, by @KaifAhmad1):
-`ConsoleProgressDisplay.update()` had 5 direct `sys.stdout.write()` calls that bypassed the existing `_safe_write()` guard, causing `UnicodeEncodeError` when emoji characters (`🧠`, `📊`) were written to cp1252-encoded consoles during any progress-tracked operation.
- All 5 calls replaced with `self._safe_write()`, which catches `UnicodeEncodeError` and re-encodes output with `errors="replace"` so progress output never crashes the process.
- Added `TestProgressTrackerEncoding` regression class (3 tests) covering `_safe_write` safety, pipeline header write, and auto emoji-disable on cp1252 stdout.
- **Fix: Break circular import in `semantic_extract`; address Qodo review bug** (issue #528, PR #536, by @ZohaibHassan16, review fixes by @KaifAhmad1):
- **Root cause** — `ner_extractor.py` imported `get_entity_method` from `methods.py`, while `methods.py` imported `Entity` from `ner_extractor.py`, creating a circular import that raised `ImportError: cannot import name 'Entity' from partially initialized module` on any import of `semantica.semantic_extract`.
-`semantica/semantic_extract/types.py` (new) — shared `Entity`, `Relation`, and `Triplet` dataclasses extracted into a dedicated module that neither side of the old cycle imports, so both `ner_extractor`, `relation_extractor`, `triplet_extractor`, and `methods` can import from it freely.
-`semantica/semantic_extract/__init__.py` — lazy-loads package-level exports so core extractor imports do not pull in optional modules (e.g. the YAML-backed semantic network extractor); added `TripleExtractor` as a compatibility alias for `TripletExtractor`; legacy re-exports from the individual extractor modules preserved for backward compatibility.
-`semantica/semantic_extract/methods.py` — updated to import shared types from `types.py`; extractor-specific imports moved to function scope where needed to prevent re-introducing the cycle.
- Added regression tests (`tests/semantic_extract/test_imports.py`) covering import order independence (methods-before-extractors and extractors-before-methods), legacy type import compatibility, `TripleExtractor` alias, and that core imports do not require `yaml`.
- **Review fix (Qodo — Py3.8 test import crash)**: `test_imports.py` annotated `_run_python` as `-> subprocess.CompletedProcess[str]`, which is not subscriptable at runtime on Python 3.8 (generic subscript on built-in types requires 3.9+). Added `from __future__ import annotations` (PEP 563) so all annotations are lazy strings never evaluated at import time, restoring compatibility with the declared `requires-python = ">=3.8"` without any behaviour change on 3.9+.
- **Fix: Lazy-load optional ingest backends; address Qodo review bugs** (issue #527, PR #535, by @ZohaibHassan16, review fixes by @KaifAhmad1):
-`semantica/ingest/__init__.py` — core exports (`FileIngestor`, `ingest_file`, config, registry) remain eagerly imported; all optional backends (`WebIngestor`, `FeedIngestor`, `RepoIngestor`, `EmailIngestor`, `StreamIngestor`, `DBIngestor`, `MCPIngestor`, `OntologyIngestor`, `SnowflakeIngestor`) are now deferred behind a module-level `__getattr__`, so `from semantica.ingest import FileIngestor` no longer fails when GitPython or BeautifulSoup4 are absent.
-`semantica/ingest/methods.py` — backend imports relocated into their respective ingestion functions (`ingest_web`, `ingest_feed`, `ingest_repository`, `ingest_email`) with helper `_missing_optional_dependency()` / `_is_missing_dependency()` for consistent, actionable error messages.
- **Review fix (Bug 1 — overbroad missing-dep detection)**: replaced `except ImportError` with `except ModuleNotFoundError` in all four function-level import guards and in `__getattr__`. `ImportError` catches failures thrown by code *inside* a successfully found module, masking real bugs with a misleading "package not installed" message; `ModuleNotFoundError` (its subclass) is specific to absent modules. Simplified `_is_missing_dependency` to rely solely on `exc.name` now that `ModuleNotFoundError` always sets it.
- **Review fix (Bug 2 — expected errors logged as failures)**: added `except ConfigurationError: raise` before the blanket `except Exception` handlers in `ingest_web`, `ingest_feed`, `ingest_repository`, and `ingest_email`. Missing optional dependencies are expected user-configuration issues and must not produce error-level log entries.
- **Review fix (Bug 3 — test blocker not setting `exc.name`)**: `OptionalDependencyBlocker.find_spec` now sets `err.name = root_name` on the manually constructed `ModuleNotFoundError`, matching what Python's import machinery does, so `_is_missing_dependency` correctly identifies the missing package in tests.
- Added regression tests (`tests/ingest/test_optional_imports.py`) that block the `git` and `bs4` modules via a custom meta path finder and assert core imports succeed and backends raise `ConfigurationError` with an actionable message.
- **Fix: Ontology Hub post-review bug fixes and security hardening** (follow-up to #518, closes security advisory #23, by @KaifAhmad1):
- **Broken registry filters** — `fetchRegistry` was sending toolbar filter values (`owl`, `skos`, `internal`, `external`) to the backend as the `status` query param, which only accepts `published|draft|external`, causing those filters to return empty lists. Removed the spurious `status` param; all format/kind filtering is now applied client-side via `filteredEntries`, which already had the correct logic.
- **Toggle/refresh URI corruption** — `toggle_ontology` and `refresh_ontology` applied `.removesuffix("/toggle")` / `.removesuffix("/refresh")` to the captured path parameter, which would silently corrupt any ontology URI that legitimately ends with those strings. Starlette's route regex (`/{uri:path}/toggle`) already strips the literal suffix via backtracking, so the `removesuffix` calls were removed and the raw `ontology_uri` parameter is used directly.
- **SSRF in URL fetch** — `_fetch_url_sync()` accepted arbitrary user-supplied URLs and called `requests.get()` with no validation, enabling server-side request forgery against internal services. Added `_validate_fetch_url()` which rejects non-`http`/`https` schemes and resolves the hostname via `socket.getaddrinfo`, blocking loopback, private, link-local, reserved, and multicast addresses. Applied to all three fetch sites: preview, load, and refresh.
- **File upload format misdetected** — the file picker accepted `.xml` and `.json` but `fmtMap` had no entries for those extensions, causing them to default to `turtle`. Added `xml: "xml"` and `json: "json-ld"` mappings. Changed the unknown-extension fallback from `|| "turtle"` to `?? ""` (empty string), and omit the `format` key from the request body when empty so the backend `_detect_format()` runs instead of receiving a forced incorrect value. Also added `.n3` to the accepted extension list and dropzone hint.
- **Inconsistent XML hardening** — `_parse_rdf_sync()` called `rdflib.Graph().parse()` directly, bypassing the `defusedxml`-based XXE protection already present in `semantica/explorer/utils/rdf_parser.py`. Now routes through `_safe_parse_rdf()` from that module, applying consistent protection for all RDF/XML parse paths.
- **Search scans whole graph** (`GET /api/ontology/search`) — the endpoint fetched up to 999 999 nodes and performed a linear Python substring scan on every request. Replaced with `session.search(q, limit * 6)` which uses the `GraphSearchIndex`; results are then post-filtered by `_SEARCHABLE_TYPES` and `entity_type` before being returned up to the requested limit.
- **ReDoS in format detector** (security advisory #23, CodeQL `py/polynomial-redos`, CWE-1333/730/400) — `_detect_format()` used `re.match(r"_:\w+|<[^>]+>\s+<[^>]+>", ...)` to detect N-Triples content. The `<[^>]+>\s+<[^>]+>` alternative was flagged as a polynomial regular expression on uncontrolled data. The URI-subject branch was already unreachable (strings starting with `<` return `"xml"` two lines above), so the entire regex was replaced with two O(1) string operations: `stripped.startswith("_:")` and `" <" in stripped`. `import re` removed as now unused.
- **OWLExporter Turtle syntax** (closes #478) — invalid multi-block output fixed via `_ttl_block()`; data properties no longer silently dropped; `_escape_ttl_str()` applied to all label/comment/version sites. 43 tests added.
- **[CRITICAL — CWE-95]** Eval injection in `media_parser.py`: replaced `eval(ffprobe_output)` with `fractions.Fraction`.
- **[CRITICAL — CWE-502]** Pickle deserialization in `agent_memory.py`: replaced with JSON; legacy `.pkl` files detected and refused with migration message.
- **Core Temporal Data Model** (PR #396) — `semantica.kg.temporal_model` with shared parsing/normalization/serialization helpers; `TemporalBound` and `BiTemporalFact` exported from `semantica.kg`; valid-time and transaction-time filtering; `TemporalValidationError` on invalid inputs; history-preserving revisions in `TemporalVersionManager.apply_revision()` with supersession semantics.
- **Deterministic Temporal Reasoning Engine** (PR #398) — `semantica.kg.temporal_reasoning`; full Allen interval algebra via `IntervalRelation` (all 13 relations); `TemporalReasoningEngine` with interval merging, gap analysis, coverage calculation, timelines, retroactive coverage; zero LLM calls; circular import risk between `semantica.reasoning` and `semantica.kg` eliminated.
-`RDFExporter.export_to_rdf(include_temporal=True, time_axis="valid|transaction|both")` — emits OWL-Time triples for all temporally-annotated relationships.
-`create_snapshot()` stamps `"format_version": "1.0"`; `validate_snapshot()` and `migrate_snapshot()` for stable snapshot lifecycle.
- **Temporal GraphRAG Integration** (PR #402) — `TemporalGraphRetriever` filters retrieved context to a point in time; `ContextRetriever.query_with_reasoning(at_time, header_template)` prepends structured temporal header; `TemporalQueryRewriter` extracts temporal intent (before/after/at/during/between) from natural language; regex-only by default, optional LLM-assisted mode.
**Ontology** (@KaifAhmad1@ZohaibHassan16)
- **SHACL Shape Generation & Validation** (PR #318) — `SHACLGenerator` derives SHACL node/property shapes from any ontology dict; three quality tiers (basic/standard/strict); Turtle/JSON-LD/N-Triples output; iterative multi-level inheritance propagation, cycle-safe; `OntologyEngine.to_shacl()`, `export_shacl()`, `validate_graph(explain=True)`; `SHACLValidationReport` with plain-English explanations for all 7 constraint types. `pip install semantica[shacl]`.
- **Thread safety** (PR #385) — `ContextGraph` and `GraphSession` protected with `threading.RLock`; 8 analytics components lazily initialized under lock.
- **In-memory fallbacks** (PR #386) — All 7 `DecisionQuery` and 4 `DecisionRecorder` methods have `ContextGraph` fallback paths for in-memory usage without a graph DB.
- **Snapshot schema compatibility** (PR #393) — accepts both `nodes`/`edges` and `entities`/`relationships` snapshot schemas transparently; metadata counts always accurate.
- **DecisionQuery/DecisionRecorder fallbacks** (PR #386) — `type()` guard instead of `isinstance()` for Mock safety; flat property storage in `_store_decision_node`; spurious `properties={}` kwarg removed; tz-aware/naive datetime mismatch resolved; `find_edges()` hoisted out of BFS loop (O(nodes×edges) → O(1) per call).
- **Snapshot schema** (PR #393) — silent restore failures when `nodes`/`edges` schema didn't match legacy `entities`/`relationships` expectations.
- **Context explainability** (@KaifAhmad1) — decision nodes now store full `scenario`/`reasoning` text; causal/precedent reconstruction returns enriched `Decision` objects; `PolicyEngine.get_affected_decisions()` consistent across Cypher and fallback branches.
### Security
- **CWE-312/359/532** — Removed `api_key` debug `print` blocks from `relation_extractor.py` and `triplet_extractor.py`.
- **CWE-20** — URL sanitization: `"url" in urls` replaced with `any(url == "url" for url in urls)`, eliminating substring match.
- **CI overpermissions** — `permissions: contents: read` added to `benchmark.yml` and `security.yml`.
- **SHACL path traversal** (PR #318) — replaced `len < 500 and "\n" not in s` heuristic with `os.path.exists()`.
- **SHACL inheritance mutation** (PR #318) — `_propagate_inheritance` uses `dataclasses.replace()` instead of appending parent `PropertyShape` objects by reference.
- **Ingest Unit Tests** (Issues #239#232, @Mohammed2372) — file, web, and feed ingestors; 998 lines of tests; 80–86% coverage.
- TextNormalizer comprehensive unit tests (PR #242, @ZohaibHassan16).
### Fixed
- **Temperature Compatibility** (Issues #256#252, @F0rt1s@IGES-Institut) — `temperature=None` now omits parameter so APIs use model defaults; `_add_if_set` helper applied to all 5 providers; 10 tests.
- **JenaStore Empty Graph** (Issues #257#258, @ZohaibHassan16) — `if self.graph is None:` replaces implicit falsy check in 5 methods.
---
## [0.2.5] - 2026-01-27

- Implemented native Pinecone support (`PineconeStore`) with full CRUD capabilities.
- Added support for serverless and pod-based indexes, namespaces, and metadata filtering.
- Integrated with `VectorStore` unified interface and registry.
- (Closes #219, Resolves #220)
- **Configurable LLM Retry Logic**:
- Exposed `max_retries` parameter in `NERExtractor`, `RelationExtractor`, `TripletExtractor` and low-level extraction methods (`extract_entities_llm`, `extract_relations_llm`, `extract_triplets_llm`).
- Defaults to 3 retries to prevent infinite loops during JSON validation failures or API timeouts.
- Propagated retry configuration through chunked processing helpers to ensure consistent behavior for long documents.
- Updated `03_Earnings_Call_Analysis.ipynb` to use `max_retries=3` by default.
### Added
- **Bring Your Own Model (BYOM) Support**:
- Enabled full support for custom HuggingFace models in `NERExtractor`, `RelationExtractor`, and `TripletExtractor`.
- Added support for custom tokenizers in `HuggingFaceModelLoader` to handle models with non-standard tokenization requirements.
- Implemented robust fallback logic for model selection: runtime options (`extract(model=...)`) now correctly override configuration defaults.
- **Enhanced NER Implementation**:
- Added configurable aggregation strategies (`simple`, `first`, `average`, `max`) to `extract_entities_huggingface` for better sub-word token handling.
- Implemented robust IOB/BILOU parsing to reconstruct entities from raw model outputs when structured output is unavailable.
- Added confidence scoring for aggregated entities.
- **Relation Extraction Improvements**:
- Implemented standard entity marker technique (wrapping subject/object with `<subj>`, `<obj>` tags) in `extract_relations_huggingface` for compatibility with sequence classification models.
- Added structured output parsing to convert raw model predictions into validated `Relation` objects.
- **Triplet Extraction Completion**:
- Added specialized parsing for Seq2Seq models (e.g., REBEL) in `extract_triplets_huggingface` to generate structured triplets directly from text.
- Implemented post-processing logic to clean and validate generated triplets.
- **Triplet Extraction** — Seq2Seq model support (REBEL) for direct structured triplet generation from text.
### Fixed
- **LLM Extraction Stability**:
- Fixed infinite retry loops in `BaseProvider` by strictly enforcing `max_retries` limit during structured output generation.
- Resolved stuck execution in earnings call analysis notebooks when using smaller models (e.g., Llama 3 8B) that frequently produce invalid JSON.
-**Model Parameter Precedence**:
- Fixed issue where configuration defaults took precedence over runtime arguments in Hugging Face extractors. Runtime options now correctly override config values.
- **Import Handling**:
- Fixed circular import issues in test suites by implementing robust mocking strategies.
- When enabled, progress falls back to console-style output, preventing infinite scrolling and JupyterLab out-of-memory errors
### Added
- **Comprehensive Test Suite**:
- - Added unit tests (`tests/test_relations_llm.py`) with mocked LLM provider covering both typed and structured response paths
- - Added integration tests (`tests/integration/test_relations_groq.py`) for real Groq API calls with environment variable API key
- - Tests validate relation extraction completion and result parsing across different response formats
- **Amazon Neptune Dev Environment**:
- - Added CloudFormation template (`cookbook/introduction/neptune-setup.yaml`) to provision a dev Neptune cluster with public endpoint and IAM auth enabled
- - Documented deployment, cost estimates, and IAM User vs IAM Role best practices in `cookbook/introduction/21_Amazon_Neptune_Store.ipynb`
- - Added `cfn-lint` to `.pre-commit-config.yaml` for validating CloudFormation templates while excluding `neptune-setup.yaml` from generic YAML linters
- **Vector Store High-Performance Ingestion**:
- - Added `VectorStore.add_documents` for high-throughput ingestion with automatic embedding generation, batching, and parallel processing
- - Added `VectorStore.embed_batch` helper for generating embeddings for lists of texts without immediately storing them
- - Enabled default parallel ingestion in `VectorStore` with `max_workers=6` for common workloads
- - Added dedicated documentation page `docs/vector_store_usage.md` describing high-performance vector store usage and configuration
- - Added `tests/vector_store/test_vector_store_parallel.py` covering parallel vs sequential performance, error handling, and edge cases for `add_documents` and `embed_batch`
-Amazon Neptune dev environment — CloudFormation template; `cfn-lint` in pre-commit.
-Vector Store high-performance ingestion — `VectorStore.add_documents()` with batching and parallel processing (`max_workers=6`); `VectorStore.embed_batch()` helper.
-LLM relation extraction tests (mocked and Groq integration).
### Changed
- **Relation Extraction API**:
- - Simplified parameter interface by removing unused kwargs that were previously ignored
- - Improved error handling and verbose logging for debugging relation extraction issues
- - Enhanced robustness of post-response parsing across different LLM providers
- **Vector Store Defaults and Examples**:
- - Standardized `VectorStore` default concurrency to `max_workers=6` for parallel ingestion
- - Updated vector store reference documentation and usage guides to rely on implicit defaults instead of requiring manual `max_workers` configuration in examples
- Standardized `VectorStore` concurrency defaults; implicit `max_workers=6` in examples.
### Fixed
- **LLM Relation Extraction Parsing** — normalized typed responses to consistent dict format before parsing; structured JSON fallback; extra kwargs removed from internals.
- Implemented high-throughput parallel batch processing across all core extractors (`NERExtractor`, `RelationExtractor`, `TripletExtractor`, `EventDetector`, `SemanticNetworkExtractor`) using `concurrent.futures.ThreadPoolExecutor`.
- Added `max_workers` configuration parameter (default: 1) to all extractor `extract()` methods, allowing users to tune concurrency based on available CPU cores or API rate limits.
- **Parallel Chunking**: Implemented parallel processing for large document chunking in `_extract_entities_chunked` and `_extract_relations_chunked`, significantly reducing latency for long-form text analysis.
- **Thread-Safe Progress Tracking**: Enhanced `ProgressTracker` to handle concurrent updates from multiple threads without race conditions during batch processing.
- **Semantic Extract Performance & Regression**:
- Added edge-case regression suite covering max worker defaults, LLM prompt entity filtering, and extractor reuse.
- Added a runnable real-use-case benchmark script for batch latency across `NERExtractor`, `RelationExtractor`, `TripletExtractor`, `EventDetector`, `SemanticAnalyzer`, and `SemanticNetworkExtractor`.
- Added Groq LLM smoke tests that exercise LLM-based entities/relations/triplets when `GROQ_API_KEY` is available via environment configuration.
### Security
-**Credential Sanitization**:
- Removed hardcoded API keys from 8 cookbook notebooks to prevent secret leakage.
- Enforced environment variable usage for `GROQ_API_KEY` across all examples.
- **Secure Caching**:
- Updated `ExtractionCache` to exclude sensitive parameters (e.g., `api_key`, `token`, `password`) from cache key generation, preventing secret leakage and enabling safe cache sharing.
- Upgraded cache key hashing algorithm from MD5 to **SHA-256** for enhanced collision resistance and security.
- **Parallel Extraction Engine** — `concurrent.futures.ThreadPoolExecutor` across all extractors (`NERExtractor`, `RelationExtractor`, `TripletExtractor`, `EventDetector`, `SemanticNetworkExtractor`); `max_workers` parameter; thread-safe `ProgressTracker`.
- Migrated `GeminiProvider` to use the new `google-genai` SDK (v0.1.0+) to address deprecation warnings.
- Implemented graceful fallback to `google.generativeai` for backward compatibility.
-**Dependency Resolution**:
- Pinned `opentelemetry-api` and `opentelemetry-sdk` to `1.37.0` to resolve pip conflicts.
- Updated `protobuf` and `grpcio` constraints for better stability.
- **Entity Filtering Scope**:
- Removed entity filtering from non-LLM extraction flows to avoid accuracy regressions.
- Appliedentity downselection only to LLM relation prompt construction, while matching returned entities against the full original entity list.
- **Batch Concurrency Defaults**:
- Standardized `max_workers` defaulting across `semantic_extract` and tuned for low-latency: ML-backed methods default to single-worker, while pattern/regex/rules/LLM/huggingface methods use a higher parallelism default capped by CPU.
- Raised the global `optimization.max_workers` default to 8 for better throughput on batch workloads.
- **Gemini SDK Migration** — `google-genai` SDK with `google.generativeai` fallback.
- Pinned `opentelemetry-api`/`-sdk` to 1.37.0; updated `protobuf`/`grpcio` constraints.
-Entity filtering applied only to LLM prompt construction, not non-LLM flows.
- Raised global `optimization.max_workers` default to 8.
### Security
- **Credential sanitization** — hardcoded API keys removed from 8 notebooks; `ExtractionCache` excludes `api_key`/`token`/`password` from cache keys; cache key hashing upgraded MD5 → SHA-256.
- **Resolved Bottleneck #1 (Sequential Processing)**: Replaced sequential `for` loops with parallel execution for both document-level batches and intra-document chunks.
- **Performance Gains**: Achieved **~1.89x speedup** in real-world extraction scenarios (tested with Groq `llama-3.3-70b-versatile` on standard datasets).
- **Initialization Optimization**: Refactored test suite to use class-level `setUpClass` for LLM provider initialization, eliminating redundant API client creation overhead.
- **Low-Latency Entity Matching**:
- Avoided heavyweight embedding stack imports on common matches by improving fast matching heuristics and short-circuiting before embedding similarity.
- Optimized entity matching to prioritize exact/substring/word-boundary matches and only fall back to embedding similarity when needed, reducing CPU overhead in LLM relation/triplet mapping.
- ~1.89× speedup via parallel extraction (Groq `llama-3.3-70b-versatile`, standard datasets).
- Optimized entity matching: exact/substring/word-boundary fast paths before embedding similarity.

## 3. Release Steps
### Automated Release (Recommended)
The project uses GitHub Actions for automated releases to PyPI.
1.29. **Tag the commit**: Create a new git tag for the version (e.g., `v0.2.3`).
```bash
git tag -a v0.2.3 -m "Release v0.2.3"
git push origin v0.2.3
```
2. **GitHub Action**: The `Release` workflow will automatically trigger, build the package, create a GitHub Release, and publish to PyPI using Trusted Publishing.
### Manual Release
If you need to release manually:
1. **Build the package**:
```bash
python -m build
```
2. **Verify the build**:
```bash
twine check dist/*
```
3. **Upload to PyPI**:
```bash
twine upload dist/*
```
## 4. Post-release
- Verify the new version is available on [PyPI](https://pypi.org/project/semantica/).
- Check the [GitHub Releases](https://github.com/your-org/semantica/releases) page for the new release notes.
This document outlines the architecture, directory structure, and usage of the performance benchmarking suite for the Semantica Agentic RAG framework.
## Architecture
The suite is organized into modular layers mirroring the library's internal structure, which allows for isolated performance testing of specific components.
### High-Level Design Principles
- **Isolation:** Use of mocks to ensure benchmarks measure algorithm logic.
- **Virtualization:** A custom `conftest.py` virtualization layer allows tests to run without heavy local dependencies.
- **Pedantic Measurement:** High-iteration counts and statistical rounds to filter out system noise.
## Directory Structure
Based on the current production environment, the suite is organized as follows:
| core_processing/ | Throughput tests for NER, extraction, and graph building. |
| export/ | Serialization benchmarks for JSON, CSV, RDF, and GraphML. |
| infrastructure/ | Support scripts, including the regression comparison engine. |
| input_layer/ | Ingestion, parsing, and splitting performance. |
| normalize/ | Text cleaning, encoding handling, and date normalization. |
| ontology/ | Inference, serialization, and namespace management overhead. |
| output_orchestration/ | Parallelism and execution pipeline management. |
| quality_assurance/ | Deduplication and conflict resolution strategies. |
| results/ | Storage for benchmark JSON outputs and performance baselines. |
| storage/ | Latency tests for Vector stores (FAISS) and Triplet stores (Jena). |
| visualization/ | Computational cost of layout algorithms and chart rendering. |
## Usage
### Running the Suite
To run the full suite and generate a new results file:
```bash
python benchmarks/benchmark_runner.py
```
### Strict Mode (CI/CD)
The suite is designed to integrate with automated pipelines. Using the --strict flag will cause the runner to return a non-zero exit code if a performance regression greater than 15% is detected.
```bash
python benchmarks/benchmark_runner.py --strict
```
### Performance Comparison
The comparison engine (infrastructure/compare.py) uses Z-scores to distinguish between actual performance regressions and environmental noise.
- Regression: Change > 15% AND Z-score > 2.0.
- Noise: Change > 15% but Z-score < 2.0.
### Updating Baseline
When a performance change is intentional (e.g., a more complex but necessary algorithm is added), update the "gold standard" baseline:

Welcome to the Deduplication V2 engine!! This release specifically targets severe CI delays and production bottlenecks caused by massive knowledge graph deduplication workloads. By introducing smarter candidate generation, fast-fail prefilters, and semantic triplet canonicalization, we have reduced worst-case execution times by up to **80%**.
**Note:** This upgrade is **100% backward compatible.** All existing scripts, tests, and API signatures will continue to work exactly as they did before.
To utilize this new addition, you must explicitly **opt-in** using the new configuration keys detailed below.
---
### 1. Candidate Generation V2 (Beating the $O(N^2)$ Pair Explosion)
**The Problem:** The legacy engine relied on a naive first-character blocking strategy. If your dataset contained 5,000 companies starting with letter "A", the engine generated nearly 12.5 million candidate pairs.
**The problem:** The legacy relationship deduplication relied on exact `(Subject, Predicate, Object)` string matches. It couldn't recognize that `(Person, "works_for", Company)` is semantically identical to `(Person, "employed_by", Company)` .
**The V2 Solution:** A new `semantic_v2` mode that introduces predicate synonym mapping, literal normalization (cleaning up rogue spaces/casing), and a highly optimized $O(1)$ canonical hash path for fast matching.
**How to Opt-In**
When calling relationship-specific dedup methods, pass the new configuration keys:
```python
from semantica.deduplication import DuplicateDetector
from semantica.deduplication.methods import dedup_triplets
When using `semantic_v2` for relationships, the `MergeStrategyManager` will now automatically respect your canonicalized keys. If two entities share a relationship that differs only by a mapped synonym, the engine will correctly identify them as the same relationship and prevent duplicate graph edges during the merge phase.
### Need Help?
If you experience any unexpected behavior when switching from `legacy` to `blocking_v2` or `semantic_v2`, please check the explainability metadata (by setting `"score_breakdown_enabled": True`) to audit the exact scoring process, or open an issue on GitHub.
Semantica's modular, extensible framework for semantic intelligence and knowledge engineering.
Semantica is built around a three-layer, modular architecture designed for independent use of components, clean separation of concerns, and extensibility at each layer.
---
## Design Principles
- **Modular**: Independent, reusable components
- **Extensible**: Easy to add new functionality
- **Scalable**: Handle large-scale data processing
For full module documentation, see the [Modules Guide](modules.md).
---
## Extension Points
### Custom Ingestors
### Custom Ingestor
```python
from semantica.ingest import BaseIngestor
class CustomIngestor(BaseIngestor):
def ingest(self, source):
# Custom ingestion logic
pass
# Return a list of document dicts
...
```
### Custom Extractors
### Custom Extractor
```python
from semantica.semantic_extract import BaseExtractor
class CustomExtractor(BaseExtractor):
def extract(self, text):
# Custom extraction logic
pass
# Return a list of entity dicts
...
```
### Custom Validators
Validators can be implemented within domain-specific modules (e.g., graph or ontology) as needed.
---
## Design Decisions
### Modularity
Independent components that can be used standalone or together. Easy to test, maintain, and extend.
**Modularity** — every component can be used standalone. Import only what you need; the framework never forces a full stack.
### Plugin System
Extensible architecture allowing custom functionality without modifying core code.
**Pluggability** — extend any layer without modifying core code. Custom ingestors, extractors, validators, and exporters all follow the same base class pattern.
### Configuration Management
Centralized configuration with environment variable support for different deployment environments.
**Configuration over convention** — centralized config with environment variable overrides for deployment flexibility.
### Error Handling
Comprehensive error handling with graceful degradation and recovery mechanisms.
**Provenance by default** — lineage tracking is built into graph construction, not bolted on. Every node traces back to a source document.

The Apache Arrow exporter provides high-performance columnar data export for Semantica's knowledge graphs, entities, and relationships. It uses explicit schemas (no inference) and writes Arrow IPC files (.arrow) that are compatible with Pandas and DuckDB.
## Features
- **Explicit Schemas**: Pre-defined schemas for entities and relationships (no inference)
- **Columnar Format**: Efficient storage and fast analytics
- **Metadata Support**: Converts metadata dictionaries to Arrow struct fields
- **Field Normalization**: Handles various entity and relationship field name variations
- **Columnar Storage**: Faster analytics on specific columns
- **Compression**: Smaller file sizes (especially with LZ4/ZSTD)
- **Zero-Copy**: Memory-efficient data transfer
- **Cross-Language**: Works with Python, R, Julia, JavaScript, and more
- **SQL Queries**: Direct querying with DuckDB without loading into memory
