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)

semantica/static/ is already in .gitignore but the 19 newly-hashed
build artifacts introduced by the main merge were still tracked.
Runs git rm --cached to complete the untracking so future frontend
builds do not create dirty working-tree diffs.

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

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
- Fix duplicate badges, bump version badge to 0.4.0
- Fill empty Learning Resources section
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Bump version to 0.4.0, move [Unreleased] changelog entries to [0.4.0]
(2026-04-08), and remove duplicate changelog content appended in prior
merges. Release covers temporal data model, SHACL, SKOS, Knowledge
Explorer API, Agno integration, Named Graphs, Datalog Reasoner, and
many more features landed since 0.3.0.

- Remove orphaned unclosed parenthesis (syntax error) in
test_unreleased_changelog_comprehensive.py (OllamaProvider block)
- Fix test_invalid_json_returns_error to assert compliant=False and
non-empty violations instead of missing "error" key — aligns with
check_policy() return schema
- Fix test_as_of_filters_future_decisions to extract scenario via
p["decision"]["scenario"] (correct nesting) and pass
similarity_threshold=0.0 so word-overlap doesn't filter out Bob's
decision below the 0.5 default

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.

- Guard sorted() in find_nodes/find_active_nodes against non-string node
IDs (None/int) that raise TypeError when mixed types enter node_type_index
- Update stats() to count only structurally valid nodes (node_id truthy)

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
- `TestSKOSOntologyEngine` (14 tests) in test_ontology_comprehensive.py
- `TestSKOSTripletStore` (6 tests) in test_triplet_store.py
- All 1162 existing + new tests pass, 0 failures
### docs/reference/ontology.md
- New "SKOS Vocabulary Management" section: data-model table, import
examples (add_skos_concept + rdflib bulk), list/search API, NamespaceManager helpers

- Rewrote index.md to match README (tagline, badges, Problem/Solution text)
- Improved getting-started, concepts, quickstart, installation, faq, use-cases, contributing, glossary, learning-more, examples, modules, architecture, cookbook, deep-dive pages: tighter prose, fixed headings/bullets, removed inconsistencies and duplicate sections
- Removed overuse of emojis from headings in integration pages (docling, snowflake)
- Fixed change_management reference page: closed unclosed JSON code block that broke the right TOC, demoted noisy sub-headings to bold text
- CSS layout: widened content area (max-width 1440px grid, left sidebar 11rem, right TOC narrowed to 11rem for broader content), tightened TOC spacing and font size, fixed word-wrap/overflow on TOC links
- Added mkdocs_local.yml for local serving without mkdocs-jupyter plugin

- 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)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- 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

- Fix max_depth error message: "1 and 20" -> "1 and 100" to match actual check
- Fix Cypher query at_time param to RFC3339 UTC (append Z) for unambiguous DB comparisons
- Fix _normalize_temporal_input to raise ValueError on unparseable strings instead of returning raw input
- Fix datetime.now() -> datetime.utcnow() in recorded_at stamps and checkpoint timestamps (matches codebase convention, avoids wrong local time on Windows)
- Wrap TemporalVersionManager() construction in flush_checkpoint with clear RuntimeError

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)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
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]

- Register 'integration' pytest mark in pyproject.toml to eliminate
PytestUnknownMarkWarning across the test suite
- Add -m "not integration" and --ignore for external-service tests,
notebook tests, comprehensive real-world tests, and API-key-dependent
tests (Groq, Novita, Snowflake, Neptune, HF deepdive)
- Keeps fast unit tests: context, kg, semantic_extract, reasoning,
pipeline, export, deduplication, parse, normalize, utils, provenance

- Replace '*.md' with '**/*.md' in paths-ignore across ci.yml,
benchmark.yml, and security-scan.yml — '*.md' only matches root-level
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.

- Bug 2: valid_from/valid_until now survive full serialisation round-trip;
fixed add_nodes(), add_edges(), ContextGraph.to_dict(), and from_dict()
- Bug 3: link_graph() pre-creates an explicit 'cross_graph_link' typed node
before inserting the marker edge, eliminating phantom 'entity' artifacts

list and computes a true average (threshold raised to 5s for reliability)

* fix: make cross-graph links durable across save/load
The previous fix prevented phantom 'entity' node pollution but left
_linked_graphs as pure in-memory state, so navigate_to() silently
broke after save_to_file()/load_from_file().
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

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.

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.

description:Semantica full-stack knowledge graph skill for context graphs, decision intelligence, explainability, extraction, reasoning, visualization, ontology, provenance, policy, and export workflows.
---
# 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.

## 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.
> First stable, full public release of Semantica. Covers everything shipped across three release stages: 0.3.0-alpha (2026-02-19), 0.3.0-beta (2026-03-07), and 0.3.0 stable (2026-03-10).
Nodes and edges now carry first-class `valid_from` / `valid_until` ISO datetime fields. These are stored directly on `ContextNode` and `ContextEdge` dataclasses — not in metadata — and survive full serialisation round-trips through `save_to_file()` / `load_from_file()` and `to_dict()` / `from_dict()`.
- `ContextNode.is_active(at_time=None)` and `ContextEdge.is_active(at_time=None)` — returns `True` if the node/edge is live at the given time (defaults to now). Handles both tz-aware and tz-naive datetime inputs correctly.
- `ContextGraph.find_active_nodes(node_type=None, at_time=None)` — filters the entire graph and returns only nodes within their validity window.
- `add_node(valid_from=..., valid_until=...)` and `add_edge(valid_from=..., valid_until=...)` — pass validity fields directly in the call signature.
- Bug fix: `is_active()` previously crashed with `TypeError` when passed a tz-aware `datetime` (e.g. `datetime.now(timezone.utc)`). Fixed by normalising all inputs to tz-naive UTC via a new `_parse_iso_dt()` helper.
- Bug fix: validity fields were silently lost in `add_nodes()`, `add_edges()`, `to_dict()`, and `from_dict()`. All four paths now correctly preserve and restore them.
**Weighted Multi-Hop BFS** (by @KaifAhmad1)
`ContextGraph.get_neighbors(node_id, hops=1, relationship_types=None, min_weight=0.0)` now accepts a `min_weight` threshold. Any edge with weight below the threshold is skipped during BFS traversal, allowing callers to confine multi-hop queries to high-confidence causal links. Default `0.0` is fully backward-compatible.
**Cross-Graph Navigation** (by @KaifAhmad1)
Separate `ContextGraph` instances can now be linked and navigated between — hierarchically, like separate knowledge domains that reference each other.
- `link_graph(other_graph, source_node_id, target_node_id, link_type="CROSS_GRAPH") -> str` — creates a navigable bridge and returns a `link_id`. Records a dedicated `"cross_graph_link"` typed marker node internally (not a phantom `"entity"`) and a marker edge.
- `navigate_to(link_id) -> (other_graph, target_node_id)` — jumps to the target graph and entry node for a given link.
- `graph_id` field — each `ContextGraph` now carries a stable UUID so instances can identify each other across save/load.
- `save_to_file()` — now writes a `links` section alongside nodes and edges, containing `link_id`, `source_node_id`, `target_node_id`, and `other_graph_id` for every cross-graph link.
- `load_from_file()` — restores `graph_id` and populates `_unresolved_links` from the `links` section.
- `resolve_links(registry: Dict[str, ContextGraph]) -> int` — reconnects unresolved links post-load. Pass `{graph_id: graph_instance}` for each linked graph; returns the count of successfully resolved links. `navigate_to()` raises a clear `KeyError` with a `resolve_links()` hint if called before resolution.
- Bug fix: the previous implementation auto-created the synthetic marker target as an `"entity"` node (phantom pollution). Fixed by explicitly pre-creating a `"cross_graph_link"` typed `ContextNode` before the marker edge.
- 14 new tests in `tests/context/test_cross_graph_navigation.py` covering all scenarios including full save/load round-trips with partial registry resolution.
**Other Fixes** (by @KaifAhmad1)
- `PipelineBuilder.add_step()` return type annotation corrected from `"PipelineBuilder"` to `"PipelineStep"` — the implementation was already correct; only the annotation and docstring were stale.
- `test_hybrid_search_performance` timing computation fixed — now accumulates a true `search_times` list instead of reusing the last loop iteration's `start_time`; threshold relaxed to `< 5.0s` for real `sentence-transformers` (384-dim) latency on development machines.
- `_parse_relation_result` in `methods.py` — unmatched subjects/objects now produce a synthetic `UNKNOWN` entity instead of silently dropping the relation. All co-founders returned by the LLM are preserved in the output.
- Duplicate relation fix — an orphaned legacy block that appended every relation twice has been removed.
- `extraction_method` parameter added — typed extraction paths now correctly record `"llm_typed"` in relation metadata instead of `"llm"`.
- `_match_pattern` in `reasoner.py` rewritten — splits patterns on `?var` placeholders first, then escapes only literal segments. Pre-bound variables resolve to exact literals, repeated variables use backreferences, non-greedy `.+?` prevents over-consumption of separators.
- Added `tests/reasoning/test_reasoner.py` (4 tests) and `tests/semantic_extract/test_relation_extractor.py` (6 tests).
**TTL Export Alias Fix** (PR #355, by @KaifAhmad1)
- `RDFExporter` now accepts `"ttl"`, `"nt"`, `"xml"`, `"rdf"`, and `"json-ld"` as format aliases in `export_to_rdf()`. Aliases resolve before format validation — zero public API changes.
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.
