### Added
- **Semantica RDF vocabulary, and deterministic entity/relationship IRIs** (#1109, closes #1107, closes #1101) by @fabio-rovai, reviewed by @KaifAhmad1
@@ -18,9 +20,11 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
- The missing-id fallback minted entity/relationship IRIs from Python's builtin `hash()`, randomised per process (`PYTHONHASHSEED`), so the same entity got a different IRI on every run and exports couldn't be diffed, deduplicated, or joined to an earlier provenance record. It also wrote `<semantica:entity_N>`, an IRI in the scheme `semantica` rather than the expansion of the declared prefix, so those nodes never joined with anything written through it. Minting now uses SHA-256 and writes a full IRI in the declared namespace; the same fix applies to the default entity/relationship types in the Turtle path
- **Fixed during review** (Qodo): the temporal fallback minted from `source_id` only, while the main serializer accepts `source_id` or `source` — relationships using the second form hashed two empty strings, which the previous randomised `hash()` masked by making the IRI unstable anyway; once deterministic, unrelated relationships at the same list index collided on one IRI across exports. Endpoints are now resolved the same way `serialize_to_turtle` resolves them, before minting. `sem:confidence` also lost its declared `xsd:decimal` range: the N-Triples serializer types the same value `xsd:float`, and the two are disjoint, so declaring either contradicted one of the exporters (tracked in #1100) — a new `test_declared_ranges_do_not_contradict_what_the_exporters_emit` guards the whole class of that mistake
- **Fixed in follow-up**: `serialize_to_rdfxml`'s default entity type still wrote the bare string `"semantica:Entity"` into an `rdf:resource` attribute, which (unlike a Turtle angle-bracket or an XML element name) is not namespace-expanded — the exact #1101 failure mode, just on the untested RDF/XML path. `json_exporter.py`'s `semantica:format` and `@type: "semantica:KnowledgeGraph"` were emitted but absent from both the vocabulary and the test's `EMITTED_TERMS` guard set, so the "undeclared terms fail the build" claim didn't actually cover them — both are now declared and guarded. `MANIFEST.in` didn't mirror the `pyproject.toml` package-data addition, so a source-distribution install could omit the vocabulary file. The cross-process minting-stability test replaced the subprocess's entire environment with a POSIX-only `PATH`, breaking it on Windows; now overrides only `PYTHONHASHSEED` on top of the inherited environment
- 229 export and ontology tests pass
- **Also fixed, on the JSON-LD paths**: the first fix covered the Turtle, N-Triples and RDF/XML serializers, and left both JSON-LD writers interpolating the entity's own text into `f"semantica:entity/{text}"` and the endpoints into `f"semantica:rel/{source}_{target}"`. Three consequences, all live in 0.6.5: an entity whose text contained a space produced an invalid IRI, and a JSON-LD parser dropped that node in full rather than reporting it, so the entity disappeared from the export; every relationship carrying `source`/`target` rather than `source_id`/`target_id` minted the identical `semantica:rel/_`, collapsing all of them onto one node whose types and endpoints merged; and the JSON-LD `@id` disagreed with the Turtle IRI for the same entity, so the two serializations of one knowledge graph were two different graphs. Both JSON-LD writers now use `mint_entity_iri`/`mint_relationship_iri`, and `JSONExporter.export_entities`/`export_relationships` declare the `semantica` prefix their `@context` was already writing `semantica:entities` against — without it a processor reads that as an IRI in the scheme `semantica`, which is the original #1101 defect on a third path
- `tests/export/test_jsonld_iri_minting.py` parses each export with a real JSON-LD processor and asserts the entity survives, the relationships stay distinct, no term expands into the `semantica` scheme, and the JSON-LD `@id` equals the Turtle IRI

- New `pip install semantica[crewai]` extra (`crewai>=0.80.0`) — crewai core provides `BaseTool`/`BaseKnowledgeSource`, so `crewai-tools` is intentionally not included, and the extra is intentionally **not** part of the `all` bundle: crewai hard-requires `chromadb~=1.1.0`, which is affected by the unpatched pre-auth code-injection CVE-2026-45829 (see `integrations/crewai/README.md`)
- `integrations/crewai/SemanticaKGTool` — a CrewAI `BaseTool` exposing 5 KG actions (`extract_entities`, `extract_relations`, `add_to_graph`, `query_graph`, `find_related`) backed by `NERExtractor` / `RelationExtractor` / `ContextGraph`; supports both sync `run()` and async `arun()`

- Previously there was no supported way to feed a `ContextGraph` into those consumers without hand-rolling the field remapping; `to_kg_dict()` does it once, with an `entities_only` option that drops relationships left dangling by the filter
- **Fixed during review** (Qodo): null `properties`/`metadata` on a node loaded from JSON raised `TypeError` when copied — both are now guarded with `or {}`; entity ids are coerced to `str(node_id)` to match `ContextEdge`'s already-str-coerced endpoints, so valid relationships were no longer dropped by `entities_only` filtering
- `RDFExporter`'s validator and `TemporalGraphQuery` now also accept `source_id`/`target_id` endpoints, the shape `to_kg_dict()` emits
### Changed
- **`GraphBuilder`'s 6 public methods now have Google-style docstrings** (#878, closes #876) by @cakeni
@@ -59,7 +68,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
- **Corrected during review**: `add_temporal_edge`/`create_temporal_snapshot` docstrings overclaimed numeric-timestamp support; `_parse_time()` only special-cases `str` and `datetime`, falling back to a bare `str()` cast for anything else (not true numeric parsing). Narrowed to "datetime or ISO-formatted string"
- **Fixed along the way**: `build()`'s `**options` documented a default only for `extract`; `extract_relations`, `extract_triplets`, `ner_method`, `relation_method`, and `triplet_method` all have concrete defaults in `_extract_from_text()` (`True`, `True`, `"llm"`, `"llm"`, `"llm"`) that were left unstated, inconsistent with CONTRIBUTING.md's own docstring example of noting defaults inline
- `python -m pytest tests/kg/test_kg.py tests/kg/test_graph_builder_external.py -q`: 45 passed
- **`GraphBuilder` raw-text extraction now defaults to local extractors instead of LLM extraction** (closes #930) by @dex0shubham
- **`GraphBuilder` raw-text extraction now defaults to local extractors instead of LLM extraction** (#941, closes #930) by @dex0shubham
- `GraphBuilder._extract_from_text()` defaulted `ner_method`, `relation_method`, and `triplet_method` to `"llm"`, and ran relation extraction unconditionally (`extract_relations` defaulted to `True`) — all four contradicting the defaults documented in the `build()` docstring at the time (`"ml"` / `"pattern"` / `False`), and diverging from the standalone extractors (`NERExtractor` defaults to `method="ml"`, `RelationExtractor` and `TripletExtractor` to `method="pattern"`). The practical effect was that any raw-text `build()` call silently required a configured provider, an API key, and network access
- Defaults are now `ner_method="ml"`, `relation_method="pattern"`, `triplet_method="pattern"`, and `extract_relations=False`, matching the docstring. LLM extraction remains fully available and is now opt-in

- New regression coverage in `tests/kg/test_graph_builder_extraction_defaults.py` pinning all four defaults, verifying that no default resolves to `"llm"`, confirming explicit LLM opt-in still routes correctly, asserting extractors are constructed once across repeated texts, covering fallback method lists (e.g. `ner_method=["pattern", "ml"]`) for all three extractors, asserting relations are forwarded to triplet extraction (and that `None` is forwarded when relation extraction is disabled or fails), and running the real default path end to end with no provider mocked. Verified to fail against the pre-fix code
- Full `kg` suite: 473 passed
- **Explorer graph canvas now renders edge labels** (#1013, closes #1009) by @yzxcj797
- `GraphCanvas.tsx` had no edge-label rendering path at all; Sigma's edge-label renderer draws `data.label`, but the graph state stored the relationship type under `edgeType`, so simply enabling the renderer would have left every edge blank. `graphSceneState`'s edge reducer now maps `edgeType` onto `label` (suppressed for hidden edges)
- Rendering is gated behind a new `edgeLabelsEnabled` entry in the Effects panel (default on), wired through the existing `GraphEffectToggle`/`GraphEffectsState` plumbing, so dense graphs can still turn labels off
- **Fixed during review** (Qodo): two follow-up passes closed gaps the first cut left — label rendering wasn't wired through `explorationEffectsPluginPhaseC.tsx`'s Phase C variant, and toggling the effect off mid-session didn't clear already-rendered labels
- New coverage in `explorer/tests/graphSceneState.display.test.ts`
- **Removed `GraphWorkspaceShell.tsx`, `GraphRuntimeStage.tsx`, and `useGraphData.ts` — a second, unused implementation of the graph-loading/error-handling logic already fixed in `GraphWorkspace.tsx`** (#984, resolves the cleanup tracked in #981 by #980's review note) by @lakshayxi
- 1,564 lines removed; the surviving `GraphWorkspace` path is now the only implementation, so the "two copies that drifted apart" root cause #980 fixed can't recur in the copy nobody was maintaining
- **Explorer README and `docs/explorer-setup.md` corrected to describe the authentication 0.6.5 actually shipped**, plus a documented `/ws/graph-updates` auth note (#1040, fixes #1028) by @Kyou12138
- Both docs still claimed the Explorer API had no built-in authentication after v0.6.5 added mandatory `SEMANTICA_API_KEY` enforcement with a `503` fail-closed default; corrected to describe the actual behavior, including that only protected routes require the key (`/api/health`/`/api/info` stay open), the non-loopback-bind CLI warning only fires in anonymous mode or when the key is unset, and `SEMANTICA_API_KEY`/`SEMANTICA_ALLOW_ANONYMOUS` are documented in the environment-variable table
- **CI: pinned `github/codeql-action` to current v4** (#986) by @ZohaibHassan16, and **pinned Python dependencies in `requirements-ci.txt` for reproducible CI runs** (#945) by @yunaremaia, closing the gap where an unpinned CI dependency could silently change behavior between runs
- **README now states up front that Semantica's explainability is system-level, not foundation-model-internal** (#1033, #1034) by @KaifAhmad1
- Nothing in the README previously scoped what "explainable" meant, leaving readers to assume Semantica could expose or reconstruct an LLM's internal reasoning. A callout now states explicitly that Semantica explains and audits what the AI *system* did — context fed in, decisions produced, provenance, relationships, policies applied — not the model's private internal reasoning, and moved the note near the top of the README rather than leaving it implicit
### Fixed
- **Every timestamp an export or a provenance record wrote was timezone-naive** (closes #1114) by @fabio-rovai
- `semantica/export/` stamped with `datetime.now().isoformat()`, which reads the machine's **local** clock; `semantica/provenance/` stamped with `datetime.utcnow().isoformat()`, which reads **UTC**. Both produce a naive value and both serialize identically, so nothing downstream can tell which zone a given timestamp belongs to — the same string means two different instants depending on which module wrote it
- In RDF the consequence is silent rather than loud. Under XSD 1.1 a value with no timezone compared against one with a timezone is indeterminate whenever the two fall inside the ±14 hour window; SPARQL turns an indeterminate comparison into an error, and `FILTER` discards errors as non-matches. A timezone-qualified query over an Oxigraph store returns an answer with every Semantica-written record quietly absent from it, which is a poor property for `prov:generatedAtTime`, `prov:startedAtTime`, `prov:endedAtTime` and `prov:atTime` to have
- New `utc_now()`/`utc_now_iso()` in `semantica/utils/helpers.py`, exported from `semantica.utils`, and used at all 29 call sites in `export/` (`json_exporter`, `yaml_exporter`, `report_generator`, `export_provenance`) and `provenance/` (`manager`, `schemas`, `bridge_axiom`). Values now read `2026-08-19T14:19:04.229937+00:00`: one unambiguous instant, comparable against any correctly stamped value, and valid `xsd:dateTimeStamp`. `sem:exportedAt`'s range in `semantica/ontology/vocabulary/semantica-ns.ttl` is tightened from `xsd:dateTime` accordingly, and its comment no longer has to explain why the weaker range was necessary
- `datetime.utcnow()` is deprecated as of Python 3.12 and scheduled for removal; constructing a `ProvenanceEntry` under `-W error::DeprecationWarning` on 3.13 raised, and no longer does
- New `tests/export/test_timestamp_timezones.py` and `tests/provenance/test_timestamp_timezones.py`: offset presence on every export and provenance path, PROV-O literals valid as `xsd:dateTimeStamp`, comparison against a timezone-aware instant without `TypeError`, the Oxigraph filter that dropped the naive value (with a bound inside the indeterminate window, so the test cannot pass by accident), and the document `@id` remaining a valid IRI with `+00:00` in it. 11 of the 13 fail on the parent commit
- **Fixed during review** (Qodo): once new entries carry `+00:00` and stored ones do not, `ProvenanceManager.query_recorded_between` and `audit_log` compared ISO timestamps as raw strings, so they ordered by spelling rather than by instant — an inclusive naive bound naming a stored offset-bearing timestamp sorted *below* it and dropped the record, and a bound written in another offset landed wherever its digits fell (`19:45+05:30` is 14:15Z, but sorted after 14:19Z). Both now compare instants through a new `to_utc_datetime()` helper that reads a missing offset as UTC, which is what the values written before this change actually were; a bound that cannot be read as a timestamp keeps the historical string comparison rather than raising on a call that used to work
- The remaining 147 naive call sites are in `context/`, `vector_store/`, `seed/` and elsewhere, where timestamps are compared against values parsed from previously stored naive strings. Converting those without a read-side migration would raise `TypeError: can't compare offset-naive and offset-aware datetimes` on existing data, so they are deliberately left for a separate change
- **`split`/chunking paths bypassed the centralized spaCy model cache, reloading the model on every call** (#1042, closes #998) by @Accute9, reviewed by @Sameer6305
- `semantica/split/methods.py`'s `split_by_sentences()` and `semantica/split/semantic_chunker.py`'s `SemanticChunker.__init__` each called `spacy.load()` directly instead of reusing the process-level cache added in #889/`semantic_extract/methods.py`'s `load_spacy_model()` — every call/construction re-paid the ~120ms model-load cost independently of `NERExtractor`, which already used the cache
- Both now route through `load_spacy_model()`, sharing one cached `Language` instance per model name across `split_by_sentences()`, `SemanticChunker`, and `NERExtractor`; a missing model still falls back to regex/paragraph chunking without poisoning the cache for a later successful load

- **`explain_violations` rendered hardcoded placeholders (`min_count=1`, `max_count=1`) instead of the SHACL shape's real constraint values, and misused the violation message text as the datatype/class value** (#1094) by @cxzg007
- `_run_pyshacl` never read `sh:minCount`/`sh:maxCount`/`sh:datatype`/`sh:class` back from the violation's `sh:sourceShape`, so every plain-English explanation was wrong regardless of what the shape actually declared. `SHACLViolation` now carries those four fields (also exposed via `to_dict()`), populated by back-referencing `sh:sourceShape`; `explain_violations` renders the real values, falling back to `"?"` when a value is genuinely absent
- **Known limitation**: `sh:qualifiedMinCount`/`sh:qualifiedMaxCount` are not handled yet and still fall back to the `"?"` placeholder
- New regression tests cover both the rendering path and the `sh:sourceShape` back-reference (skipped when `pyshacl`/`rdflib` are absent)
- **Entity merging silently dropped `entity_id` aliases, and exact-match entity resolution had three correctness gaps** (#1086, #1026) by @T1mn
- `entity_merger.py`/`merge_strategy.py`/`entity_resolver.py` used inconsistent logic for extracting an entity's id across the merge path, so a merged entity could lose the `entity_id` aliases that let later lookups find it under its old identity. A new `semantica/utils/entity_ids.py` unifies id extraction across all three call sites
- `EntityResolver`'s exact-match path is now honored rather than silently falling through to fuzzy matching in some cases; entities with no identifier are preserved instead of being dropped, and blank exact-match names are ignored rather than matching every other blank name
- New/expanded coverage in `tests/kg/test_entity_pipeline.py` and `tests/kg/test_entity_resolver_exact.py`
- **`flatten_dict()` silently collided keys when a flattened path from one branch matched a literal key already present at the target depth** (#1062) by @shahzaib-ahmadcs
- Two differently-shaped inputs could flatten to the same output key, with the second write silently overwriting the first — no error, no warning, just a dropped value. Collisions are now detected and handled explicitly instead of overwriting
- **`ExcelParser.__init__` raised `NameError` on every instantiation — `get_progress_tracker()` was called but never imported** (#1016, closes #1014) by @pravit-amp
- Same defect as the one fixed for `SimilarityCalculator` in #530, this time in `semantica/parse/excel_parser.py`; the existing test imported the class but never constructed it, so nothing caught the missing import. Added construction coverage for every parser exported from `semantica.parse`, driven off `__all__` so future additions are covered automatically, living outside `test_parse_comprehensive.py` (whose `setUp` mocks `get_progress_tracker` into each module and would mock away the exact interaction under test)
- **Graph analytics (`centrality_calculator.py`, `community_detector.py`, `connectivity_analyzer.py`) dropped isolated nodes and diverged on how each computed its working view of the graph** (#1011) by @T1mn
- Each analyzer had its own ad hoc logic for building the node/edge set it operated over, and none of them included nodes with no edges — a node with zero connections simply vanished from centrality scores, community assignments, and connectivity reports instead of appearing with a zero/singleton value. A new shared `semantica/kg/_graph_view.py` centralizes graph-view construction (including node fallbacks and community payload shaping) for all three analyzers, which are now ~250 lines lighter combined
- New `tests/kg/test_analytics_node_scope.py` covering isolated-node presence across all three analyzers
- **Explorer fired temporal-bounds and snapshot requests before the graph itself had loaded, tripling failed requests when the backend was down and leaving the timeline scrubber with nothing to scrub** (#1003) by @lakshayxi
- Two new predicate functions gate the temporal effects on the graph having actually loaded (an empty graph still counts as loaded); confirmed against a downed backend that this cuts three failing requests per page load down to one
- **`SeedDataManager.load_from_database()` never actually reached the database, and connection failures were mislabeled as a missing optional dependency** (#995, closes #973) by @yzxcj797
- `DBIngestor.execute_query`/`export_table` need the connection string as their first positional argument; `load_from_database()` only passed it into the constructor's config dict, which those methods never read, so every call raised `TypeError` before connecting. Also split the combined `except (ImportError, OSError)` handling apart — a genuine connection failure was reported as `"module not available"`, sending debugging in the wrong direction; `OSError` now propagates as an actual failure, chained via `from e`
- **SPARQL `CONSTRUCT` detection matched inside a leading `#`-comment, misclassifying `SELECT`/`ASK` queries as `CONSTRUCT` across all four SPARQL backends** (#951) by @pravit-amp
- `CONSTRUCT_QUERY_RE` skipped comments with a bare `\#[^\n]*`, whose backtracking `*` let a `# CONSTRUCT ...` comment line "swallow" the real query-form keyword on the next line for a query like `# CONSTRUCT ...\nSELECT ...`. The mistaken `CONSTRUCT` classification sent `Accept: text/turtle` and tried to parse a SELECT/ASK response body as Turtle, failing with a misleading parse error. The regex now requires a comment to reach a line terminator (LF or CR, per the SPARQL grammar) before matching
- **`k_shortest_paths` mutated caller-visible graph state during traversal and ignored direction when excluding already-used edges** (#1000) by @T1mn
- `semantica/kg/path_finder.py`'s search left side effects behind after returning, and edge exclusion during Yen's-algorithm-style path removal didn't respect the traversal direction of directed graphs, letting a later search see edges that should have been available. Both fixed; new coverage in `tests/kg/test_path_finder.py`
- **`trace_decision_causality()` ignored explicitly recorded causal edges, inferring causes only from shared NER entities plus timestamp ordering** (#983) by @hsd2514
- A `CAUSED`/`INFLUENCED`/`PRECEDENT_FOR` edge added via `add_causal_relationship()` had no effect on the trace — when entity extraction found nothing in common between two decisions, `trace_decision_chain()` came back empty even with an explicit edge stored in the graph. Explicit causal edges are now traversed first as ground truth, with entity/timestamp inference kept as an additive fallback for pairs with no explicit link; edges whose source has no decision record (e.g. a graph restored via `from_dict`) are skipped so a stale edge can't abort the trace
- **`RepoIngestor`'s module-level DNS resolve cache had no lock, raising `RuntimeError: OrderedDict mutated during iteration` under concurrent `ingest_repository()` calls** (#979) by @manjunathbhaskar
- `_REPO_HOST_RESOLVE_CACHE` is a shared `OrderedDict` read, written, and pruned by every thread with no synchronization — reliably reproduced with 32 threads hammering resolution under a low TTL and small cache cap. Now guarded by a lock
- **`GraphBuilder` didn't remap relationship endpoints after entity resolution merged nodes, leaving relationships pointing at ids that no longer existed in the resolved graph** (#978) by @T1mn
- New coverage in `tests/kg/test_graph_builder_external.py`; a follow-up commit hardens the remapping against edge cases found during review
- **Explorer's dev server esbuild target didn't match the browser targets the production build declares**, occasionally producing dev-only syntax errors on older browsers (#966) by @le-czs

- **`normalize`'s number normalizer accepted currency symbols without validating them against the surrounding text, and an earlier fix's currency-code matching wasn't token-bounded** (#940) by @Mr-Neutr0n, reviewed by @ZohaibHassan16
- Symbol currencies are now validated before being accepted; currency codes are matched on token boundaries so a code embedded inside a longer token no longer false-positives
- **`ContextGraph.to_dict()` was the one reader on the class that didn't hold `self._lock`, raising `RuntimeError: dictionary changed size during iteration` under a concurrent writer and risking a torn snapshot otherwise** (#929) by @pravit-amp
- Every other reader (`stats()`, `density()`, `find_nodes()`, `find_edges()`, `get_neighbors()`, `get_nodes_by_label()`, `state_at()`, `save_to_file()`) already took the lock after it was introduced; `to_dict()` predated that change and was missed. `save_to_file()` was safe only incidentally, since it builds its payload inline under its own lock rather than delegating to `to_dict()`
- **`PipelineWithProvenance` had a broken import and no working `run()` method** (#862) by @Karunasagar12
- `from .pipeline import Pipeline` failed because `Pipeline` lives in `pipeline_builder.py`, not a nonexistent `pipeline.py` — fixed to `from .pipeline_builder import Pipeline`. The class also had no `run()`; it now delegates to `ExecutionEngine.execute_pipeline()`, the intended execution path for a built `Pipeline`. The constructor now accepts a built `Pipeline` instance directly

- **SSRF via redirect bypass in ontology URL fetching** (GHSA-8c7v-62gr-hj6g, High): redirect targets are now re-validated at every hop and the connection is pinned to the validated address, closing a DNS check-then-use race
- **Cypher injection via unvalidated node labels and property keys** (GHSA-482h-hw99-h62p, Critical): Neptune, Neo4j, and FalkorDB now sanitize every label/relationship-type/property-key interpolation site
- **SPARQL injection via unvalidated triplet IRIs** (GHSA-8vgg-8mr4-r236, Critical): Blazegraph, RDF4J, and Jena now validate subject/predicate/object IRIs before interpolation
- **Missing Origin validation on the WebSocket handshake** (GHSA-4643-wpgq-w329, Moderate, anonymous-mode only): `/ws/graph-updates` now checks `Origin` against the same allowlist `CORSMiddleware` enforces for HTTP
- **Polynomial ReDoS in SPARQL query validation** (CodeQL `py/polynomial-redos`): fixed a backtracking regex in the Explorer's SPARQL route
- **Tarball restore path traversal**: `semantica backup restore` now validates every archive member for path containment and rejects symlink/hardlink escapes before extraction
- **Latent SQL injection in `DataExporter.export_table_data()`**: table/schema names are now identifier-allowlisted and `where`/`order_by` fragments are blocklist-checked
- **DNS-rebinding TOCTOU in the shared SSRF guard**: the resolved IP that passes validation is now the one the connection is pinned to, closing the check-then-use race (also closes the `100.64.0.0/10` CGNAT gap)
- **Stored XSS in HTML report generation** and **unvalidated SPARQL object IRIs in AnzoStore** (SPARQL injection): both now escape/validate before interpolation
- **`Authorization`/`Proxy-Authorization` credential leakage across redirects**, plus **SSRF gaps in `FeedIngestor`/`FeedMonitor`, `RepoIngestor`, and the MCP/public-API ingest paths**: all now route through the shared, redirect-safe SSRF guard
- **HTTP response header injection and an unbounded-memory DoS** in the Explorer API, and a **`fastapi`/`python-multipart` ReDoS** (PYSEC-2024-38): floors raised, inputs sanitized, candidate pools capped
Also includes: embedded Oxigraph backend for `TripletStore`, PROV-O trust/spec completeness for `ProvenanceManager`, and the Altair Anzo triplet store backend.
Also ships: **first-class CrewAI integration** (`semantica[crewai]`, extraction/decision tools + a knowledge source), **`ContextGraph` retraction and purge** (GDPR-style erasure without a full `clear()`), a declared **Semantica RDF vocabulary with deterministic entity/relationship IRIs** (stable, diffable exports), and **timezone-aware timestamps** across `export/` and `provenance/`.

"""The JSON-LD paths must mint the same IRIs as the RDF paths (issue #1101).
#1101 was fixed for the Turtle, N-Triples and RDF/XML serializers: an entity
arriving without an id gets a deterministic IRI in the declared namespace. The
JSON-LD paths were left interpolating the entity's own text into
``f"semantica:entity/{text}"`` and the relationship's endpoints into
``f"semantica:rel/{source}_{target}"``, which fails three ways:
* a text containing a space produces an invalid IRI, and a JSON-LD parser drops
the whole node rather than complaining, so the entity vanishes from the export;
* relationships carrying ``source``/``target`` rather than ``source_id``/
``target_id`` all minted ``semantica:rel/_``, so every one of them collapsed
onto a single node whose types and endpoints merged;
* the JSON-LD @id and the Turtle IRI for one entity disagreed, so the two
serializations of one knowledge graph were two different graphs.
``JSONExporter.export_entities`` and ``export_relationships`` also wrote
``semantica:entities`` into a context that never declared the ``semantica``
prefix, which a JSON-LD processor reads as an IRI in the scheme ``semantica`` —

"""
Regression tests for #1103.
OWLExporter read `object_properties` / `data_properties` while OntologyGenerator
emits a single `properties` list, so every generated property was dropped. Class
IRIs arrived as None and were interpolated into `<>`, collapsing every class onto
the empty relative IRI, so an ontology of N classes serialised as one node
carrying N labels.
These tests drive the exporter with what the generator actually produces, and
assert on the parsed graph rather than on the serialised text.

"""Timestamps that leave the process must carry a timezone (issue #1114).
Every timestamp an exporter wrote was naive: ``datetime.now().isoformat()``
reads the local clock, ``datetime.utcnow().isoformat()`` reads UTC, and the two
serialize identically, so nothing downstream can tell which zone a value belongs
to. In RDF the consequence is not a parse error but a silent one: under XSD 1.1
a value with no timezone compared against one with a timezone is indeterminate
whenever they fall inside the +/-14 hour window, SPARQL turns that into an error,
and FILTER discards errors as non-matches. A timezone-qualified query therefore
