Prevent self-recursion in methods.py: generate_embeddings, embed_text, calculate_similarity, and pool_embeddings all registered themselves as custom methods, causing infinite self-calls when dispatch invoked them without explicitly passing method parameter. Fix: check custom_method is not the function itself before recursing. 2. Fix embed generate --output corrupt output: the CLI wrote json.dumps(result, default=str) which produced plaintext repr of numpy arrays (e.g. '[1.49e-01 4.85e-02 ...]') instead of proper Parquet. Fix: detect .parquet extension (case-insensitive), convert numpy array to pandas DataFrame with dim_* columns and id index, use to_parquet(). Non-parquet extensions fall back to JSON with clear ImportError message. 3. Add pyarrow>=14.0.0 to core dependencies (previously only in ingest-parquet/ingest-arrow optional extras). The documented quick-start flow of embed generate --output ... requires pyarrow out of the box. (Note: pandas>=1.3.0 is already a core dependency; pyarrow is the missing piece.) Note: .github/workflows/* files are excluded from this PR as they require a token with workflow scope. Upstream workflows are unchanged. --- .github/workflows/benchmark.yml | 51 ----- .github/workflows/ci.yml | 83 -------- .github/workflows/codeql.yml | 97 --------- .github/workflows/defender-for-devops.yml | 88 -------- .github/workflows/docs.yml | 68 ------ .github/workflows/release.yml | 73 ------- .github/workflows/security-scan.yml | 239 ---------------------- .github/workflows/security.yml | 42 ---- .github/workflows/verify-action-pins.yml | 28 --- pyproject.toml | 3 +- semantica/cli.py | 23 ++- semantica/embeddings/methods.py | 16 +- 12 files changed, 32 insertions(+), 779 deletions(-) delete mode 100644 .github/workflows/benchmark.yml delete mode 100644 .github/workflows/ci.yml delete mode 100644 .github/workflows/codeql.yml delete mode 100644 .github/workflows/defender-for-devops.yml delete mode 100644 .github/workflows/docs.yml delete mode 100644 .github/workflows/release.yml delete mode 100644 .github/workflows/security-scan.yml delete mode 100644 .github/workflows/security.yml delete mode 100644 .github/workflows/verify-action-pins.yml diff --git a/.github/workflows/benchmark.yml b/.github/workflows/benchmark.yml deleted file mode 100644 index 0157ee24..00000000 --- a/.github/workflows/benchmark.yml +++ /dev/null @@ -1,51 +0,0 @@ -name: Semantica Performance Suite - -on: - workflow_dispatch: - -permissions: - contents: read - -jobs: - performance-test: - name: Benchmark Runner (Ubuntu/Python 3.12) - runs-on: ubuntu-latest - - steps: - - name: Checkout Code - uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7 - with: - fetch-depth: 0 - - - name: Set up Python 3.11 - uses: actions/setup-python@5fda3b95a4ea91299a34e894583c3862153e4b97 # v7 - with: - python-version: "3.11" - cache: 'pip' - - - name: Install Dependencies - env: - - BENCHMARK_REAL_LIBS: "1" - run: | - python -m pip install --upgrade pip - pip install -e . - pip install -r benchmarks/requirements.txt - python -m spacy download en_core_web_sm - pip install rdflib neo4j faiss-cpu torch pyarrow pdfplumber python-pptx openpyxl lxml python-docx beautifulsoup4 chardet langdetect - - - name: Execute Benchmarks (Real Mode) - env: - BENCHMARK_REAL_LIBS: "1" - run: | - python benchmarks/benchmarks_runner.py - # Optional: Compare to baseline (requires previous run artifact) - # pytest-benchmark --storage file://benchmarks/results --benchmark-compare - - - name: Upload Benchmark Results - uses: actions/upload-artifact@043fb46d1a93c77aae656e7c1c64a875d1fc6a0a # v7 - if: always() - with: - name: benchmark-report-${{ github.run_id }} - path: benchmarks/results - retention-days: 30 diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml deleted file mode 100644 index 4ea31ff8..00000000 --- a/.github/workflows/ci.yml +++ /dev/null @@ -1,83 +0,0 @@ -name: CI - -permissions: - contents: read - -on: - push: - branches: [main] - paths-ignore: - - 'docs/**' - - 'docs_check.py' - - '**/*.md' - pull_request: - branches: [main] - paths-ignore: - - 'docs/**' - - 'docs_check.py' - - '**/*.md' - -jobs: - build: - runs-on: ubuntu-latest - steps: - - uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7 - - uses: actions/setup-python@5fda3b95a4ea91299a34e894583c3862153e4b97 # v7 - with: - python-version: '3.11' - - uses: actions/setup-node@820762786026740c76f36085b0efc47a31fe5020 # v7 - with: - node-version: '20' - cache: 'npm' - cache-dependency-path: explorer/package-lock.json - - name: Install Explorer frontend dependencies - working-directory: explorer - run: npm ci - - name: Test Explorer frontend - working-directory: explorer - run: | - npm run test:graph-store - npm run test:graph-workspace - npm run test:plugin-registry - - name: Build Explorer frontend - working-directory: explorer - run: npm run build - - name: Install pinned Python dependencies - run: | - pip install -r requirements-ci.txt - - name: Verify requirements-ci.txt is up to date - run: | - pip install uv==0.12.1 - # Re-resolve with the committed file as a constraint: upstream package - # releases must NOT fail CI (deps only change when pyproject.toml - # changes intentionally).

This is the same `Graph` -> `Dataset` migration #757 made for `JenaStore` (#756); the ingest path was not covered by it. Measured on the 12-line reproduction from the issue: before classes=0 properties=0 after classes=2 properties=0 On a real ontology the gap is larger: 25 triples / 1 subject against 719 / 88 for the document that surfaced this. Tests: `tests/ingest/test_ontology_named_graph.py` covers the named-graph document, keeps a canary on the default-graph document so the fix cannot trade one blind spot for another, and asserts that the reported result matches the terms returned. Reverting `Dataset()` to `Graph()` turns all four red. `tests/ontology`, `tests/export` and `tests/ingest` pass apart from six failures in web/feed/database/API ingestion, unrelated to this change and failing the same way on an unmodified checkout. Not included, and happy to add here or as a follow-up: making a load that yields zero classes stop returning `status: "success"`. That value is what made this take an afternoon to find, but it is a behaviour change on a different layer and seemed worth reviewing on its own. --- semantica/ingest/ontology_ingestor.py | 22 ++++-- tests/ingest/test_ontology_named_graph.py | 92 +++++++++++++++++++++++ 2 files changed, 108 insertions(+), 6 deletions(-) create mode 100644 tests/ingest/test_ontology_named_graph.py diff --git a/semantica/ingest/ontology_ingestor.py b/semantica/ingest/ontology_ingestor.py index 3b8638f9..1268b3db 100644 --- a/semantica/ingest/ontology_ingestor.py +++ b/semantica/ingest/ontology_ingestor.py @@ -40,7 +40,7 @@ from pathlib import Path from typing import Any, Dict, List, Optional, Union import rdflib -from rdflib import RDF, RDFS, OWL, Graph +from rdflib import RDF, RDFS, OWL, Dataset, Graph from ..utils.exceptions import ProcessingError, ValidationError from ..utils.logging import get_logger @@ -106,15 +106,21 @@ class OntologyIngestor: raise ValidationError(f"File not found: {file_path}") self.progress.update_tracking(tracking_id, message="Parsing RDF graph...") - g = Graph() - + # `Dataset`, not `Graph`: a JSON-LD document with a top-level `@id` *and* + # `@graph` places its terms in a NAMED graph. `Graph.parse()` loads only the + # default graph and discards the rest without an error, so every class and + # property in such a document was dropped while the load reported success. + # Parsing into a Dataset and flattening the quads keeps both.

Turtle, N-Triples, RDF/XML and RDFExporter's JSON-LD each write an entity's id, type, text and confidence and nothing else, so an entity keeps its confidence score and loses what produced it. JSONExporter's json-ld path keeps the same fields, which is how one knowledge graph exported two ways carried the user's data through one exporter and none through the other. Measured on e3405ebc with an entity carrying four metadata keys: 3 triples per format, 0 of them metadata. With this change: 7 triples per format, 4 of them metadata, and the same four in all four formats. The keys Semantica itself writes are mapped to declared terms in DEFAULT_METADATA_TERMS and declared in semantica-ns.ttl. A key the caller supplied is not: which namespace an arbitrary key belongs in is #1146, and that issue is open on the maintainer's modelling call, so the exporter warns and skips rather than inventing an IRI. Callers who already know the answer pass metadata_terms={key: iri}. Two keys cannot keep their own name. sem:source is already the ObjectProperty holding the subject of a reified relationship, so the Neo4j loader's "source" is written as sem:sourceSystem and its "uri" as sem:sourceUri, the one term whose value is a node rather than a literal. sem:builtAt and sem:snapshotAt have range xsd:string, not xsd:dateTime. GraphBuilder stamps with a timezone-naive datetime.now(), and #1114 is the demonstration of what typing such a value as xsd:dateTime costs: a timezone-qualified SPARQL filter over it silently drops the row. #1121 swept export and provenance and deliberately left kg/ alone. Graph-level metadata is written only when the caller names the graph with graph_uri, because this serializer has never minted a document node and #1147 is where that default belongs once it lands. The lexical form and datatype of a value are chosen once, in _typed_literal_parts, so the four serializers cannot come to disagree about them the way they disagreed about confidence in #1100. The JSON-LD path writes explicit @value/@type rather than JSON's native numbers, which would have made an integer xsd:double there and xsd:integer everywhere else. 21 tests, asserting on the parsed graph in all four formats. Output is unchanged when no metadata is present. Full-suite failure set is identical to the parent commit: 512 = 512. --- semantica/export/rdf_exporter.py | 311 +++++++++++++++++- .../ontology/vocabulary/semantica-ns.ttl | 84 +++++ tests/export/test_metadata_passthrough.py | 228 +++++++++++++ 3 files changed, 613 insertions(+), 10 deletions(-) create mode 100644 tests/export/test_metadata_passthrough.py diff --git a/semantica/export/rdf_exporter.py b/semantica/export/rdf_exporter.py index de3d0dd0..af5a21c3 100644 --- a/semantica/export/rdf_exporter.py +++ b/semantica/export/rdf_exporter.py @@ -69,6 +69,187 @@ def mint_relationship_iri(index: int, source: Any, target: Any) -> str: return f"{SEMANTICA_NS}rel_{index}_{digest}" +#: The metadata keys Semantica itself produces, and the terms they are written +#: as.

Any alias-based conversion that should've worked just raised ValidationError instead. Fixed by normalizing both units before the category check runs. Also added foot/yard/mile/gallon to the alias map - they already had conversion factors but weren't mapped to their canonical names, so they'd still have failed even after the above fix. Turned out there was a second bug hiding behind the first one: the category check defaults both sides to None, and None == None is True, so two aliases from different categories that neither resolved to a real category would silently pass instead of raising. kg -> ft would just return a number instead of erroring. Normalizing first fixes this too, since aliases now resolve to their actual categories and the mismatch gets caught. Added a regression test locking that second one down - kg->ft and gal->lb now raise ValidationError instead of silently converting.

Add a type guard: when both entities carry a non-empty type and they differ, the pair is never a duplicate candidate (confidence 0, reason 'type_mismatch'). Untyped entities and genuinely duplicate same-type pairs keep their previous behavior. Regression tests cover all three cases. * fix(dedup): honor Entity.type and exclude mismatch structurally (review fixes) Two gaps from code review (#1149): 1. _get_entity_value mapped object 'type' exclusively to .label, which Entity objects never have — their type lives on .type. The mismatch guard therefore never saw the type of Entity objects, and differently typed objects could still merge. Read .type first, fall back to .label. 2. The mismatch branch returned a normal candidate with confidence 0.0, but detection filters with >= confidence_threshold, and 0.0 is a documented valid threshold, so mismatches slipped through. Exclude type_mismatch candidates structurally at both filter sites regardless of threshold. Adds tests for Entity objects with different types and for confidence_threshold=0.0. 94 dedup tests pass. --------- --- semantica/deduplication/duplicate_detector.py | 44 ++++++++-- tests/deduplication/test_deduplication.py | 80 +++++++++++++++++++ 2 files changed, 116 insertions(+), 8 deletions(-) diff --git a/semantica/deduplication/duplicate_detector.py b/semantica/deduplication/duplicate_detector.py index c7a29d49..e5b91c11 100644 --- a/semantica/deduplication/duplicate_detector.py +++ b/semantica/deduplication/duplicate_detector.py @@ -278,8 +278,12 @@ class DuplicateDetector: for i, (entity1, entity2, score) in enumerate(similarities): candidate = self._create_duplicate_candidate(entity1, entity2, score) - # Filter by confidence threshold - if candidate.confidence >= self.confidence_threshold: + # Filter by confidence threshold; type mismatches are excluded + # structurally so no threshold value can admit them. + if ( + candidate.confidence >= self.confidence_threshold + and "type_mismatch" not in candidate.reasons + ): candidates.append(candidate) remaining = total_similarities - (i + 1) @@ -624,8 +628,12 @@ class DuplicateDetector: new_entity, existing_entity, similarity.score ) - # Filter by confidence threshold - if candidate.confidence >= self.confidence_threshold: + # Filter by confidence threshold; type mismatches are + # excluded structurally regardless of the threshold. + if ( + candidate.confidence >= self.confidence_threshold + and "type_mismatch" not in candidate.reasons + ): candidates.append(candidate) processed += 1 @@ -723,7 +731,9 @@ class DuplicateDetector: if key == "name": return getattr(entity, "text", default) if key == "type": - return getattr(entity, "label", default) + # Entity objects store the type on .type; extraction entities + # may expose .label.

A plain `python demo.py > out.txt` captured 173 bytes of progress-bar noise around 10 bytes of the program's own output. Console progress is now attached only when stdout is an interactive terminal, when running under Jupyter, or when SEMANTICA_FORCE_PROGRESS is set. FileProgressDisplay is untouched, so progress logging still works in pipelines, and SEMANTICA_DISABLE_PROGRESS keeps its existing meaning and still takes precedence. Both progress environment variables are now documented in the README and the utils reference; SEMANTICA_DISABLE_PROGRESS previously existed only in the reference page. Deviations from the issue: the issue suggested disabling the tracker on non-TTY stdout. This gates the display instead, because disabling the tracker would short-circuit before FileProgressDisplay and take file progress logging down with it, and the ~20 modules that set `progress_tracker.enabled = True` in __init__ would need the property setter taught about TTY state to avoid undoing it. Gating the display leaves both alone. Design note: the claim comment on the issue proposed an `enabled: Optional[bool] = None` constructor opt-in; during implementation the opt-in became SEMANTICA_FORCE_PROGRESS, which needs no signature change and follows the NO_COLOR/FORCE_COLOR convention. Known limitation: TTY detection runs once at tracker construction (the tracker is a process-wide singleton), so a process that redirects stdout after first use needs the env vars to change behaviour.

58aad80d56d33379f45d9ba34479ffec476e145e Mon Sep 17 00:00:00 2001 From: Sameer Kadam Date: Mon, 24 Aug 2026 21:08:46 +0530 Subject: [PATCH 071/102] fix: guard Agno and OpenClaw integration requests against SSRF (#1212) * fix: guard integration HTTP requests against SSRF * fix(openclaw): complete fallback validation and base URL handling Address the remaining review findings in the OpenClaw integration. - Strengthen fallback base_url validation to require a non-empty string, valid HTTP(S) scheme, netloc, and hostname. - Strip leading and trailing whitespace from base_url before storing it. - Replace the flaky endpoint-construction test that made a real network connection with mocked session assertions. - Add coverage for _get and _post endpoint construction and timeout forwarding. - Add regression tests for whitespace-padded base URLs and the fallback validation path. These changes complete the Qodo review fixes and harden OpenClaw URL handling without changing the intended localhost/private deployment behavior. --- integrations/agno/knowledge_graph.py | 23 +- integrations/openclaw/mcp_tool.py | 36 ++- .../integrations/agno/test_load_urls_ssrf.py | 278 +++++++++++++++++ tests/integrations/openclaw/__init__.py | 1 + .../openclaw/test_mcp_tool_ssrf.py | 290 ++++++++++++++++++ 5 files changed, 614 insertions(+), 14 deletions(-) create mode 100644 tests/integrations/agno/test_load_urls_ssrf.py create mode 100644 tests/integrations/openclaw/__init__.py create mode 100644 tests/integrations/openclaw/test_mcp_tool_ssrf.py diff --git a/integrations/agno/knowledge_graph.py b/integrations/agno/knowledge_graph.py index 21b6b280..78004bc3 100644 --- a/integrations/agno/knowledge_graph.py +++ b/integrations/agno/knowledge_graph.py @@ -277,25 +277,22 @@ class AgnoKnowledgeGraph(_KnowledgeBase): # type: ignore[misc] def load_urls(self, urls: List[str]) -> None: """Fetch each URL and ingest the response body. - Only ``http`` and ``https`` schemes are permitted to prevent SSRF. + Uses the shared SSRF guard so that ``http`` and ``https`` are the only + permitted schemes, private/loopback/link-local/cloud-metadata addresses + are blocked by default, DNS resolution is validated, and every redirect + hop is re-checked before being followed.

These are internal/private or app-layer (explorer) symbols, not part of the importable library's public API (no __all__ / package re-export), so there is no user-facing change. Removed: - poc_runner.py: parse_import_csv_row (unused nested helper) - change_management/version_storage.py: create_graph_snapshot_record - context/graph_schema.py: drop_decision_schema - explorer/dependencies.py: get_ws_manager (+ now-unused ConnectionManager import) - explorer/routes/graph.py: _extract_node_embeddings (+ stale cross-ref comment) - explorer/routes/ontology.py: ProposalState - explorer/schemas.py: ErrorResponse, TemporalSnapshotResponse, ExportResponse, StandardMessageResponse - semantic_extract/methods.py: _parse_entity_result, _parse_triplet_result - triplet_store/methods.py: _get_query_engine (+ now-unused _global_query_engine) Co-Authored-By: Vinv-AI <309466812+Vinv-AI@users.noreply.github.com> * Address review: drop now-orphaned helper and fix stale docstring - Remove _coerce_embedding_vector from explorer/routes/graph.py: its only non-recursive caller was _extract_node_embeddings (removed in this PR), so it is now dead. The live coercion logic lives in GraphSession._coerce_embedding_vector. - Update explorer/dependencies.py module docstring: it no longer injects ConnectionManager (get_ws_manager was removed); note that websocket manager access is via app.state.ws_manager. Co-Authored-By: Vinv-AI <309466812+Vinv-AI@users.noreply.github.com> * Keep public helpers with a DeprecationWarning instead of removing them create_graph_snapshot_record() and drop_decision_schema() are not underscore-prefixed, so downstream users can import them directly from their modules even though they are not re-exported from the package __init__.py. A repo search only proves there are no in-tree callers. Restore both unchanged and emit a DeprecationWarning on call, with a matching ".. deprecated::" note in each docstring pointing at the replacement. This keeps the PR non-breaking; the actual removal can happen in a future major version. The underscore-prefixed helper removals are unaffected. --------- Co-authored-by: noQbot Co-authored-by: Vinv-AI <309466812+Vinv-AI@users.noreply.github.com> Co-authored-by: noQbot --- poc_runner.py | 9 -- .../change_management/version_storage.py | 14 ++++ semantica/context/graph_schema.py | 15 ++++ semantica/explorer/dependencies.py | 16 +--- semantica/explorer/routes/graph.py | 60 -------------- semantica/explorer/routes/ontology.py | 4 - semantica/explorer/schemas.py | 23 ----- semantica/semantic_extract/methods.py | 83 ------------------- semantica/triplet_store/methods.py | 20 ----- 9 files changed, 32 insertions(+), 212 deletions(-) diff --git a/poc_runner.py b/poc_runner.py index 49b9a952..49a06a40 100644 --- a/poc_runner.py +++ b/poc_runner.py @@ -187,15 +187,6 @@ def poc_vuln3(): }) return nodes - # Simulate the CSV parser — mirrors export_import.py lines 131-133 - def parse_import_csv_row(row: dict) -> dict: - """Mirrors export_import.py CSV node ID extraction (no sanitization).""" - node_id = row.get("id") or row.get("node_id") or row.get(":ID") or row.get("_id") - return { - "id": str(node_id), # ← UNSANITIZED - "type": row.get("type", "entity"), - } - # Attack payloads payloads = [ # Header injection payload (chained with VULN-1) diff --git a/semantica/change_management/version_storage.py b/semantica/change_management/version_storage.py index c272622b..e9d75e2a 100644 --- a/semantica/change_management/version_storage.py +++ b/semantica/change_management/version_storage.py @@ -31,6 +31,7 @@ import hashlib import json import sqlite3 import threading +import warnings from abc import ABC, abstractmethod from datetime import datetime from pathlib import Path @@ -62,6 +63,12 @@ def create_graph_snapshot_record( """ Creates a standardized snapshot metadata record for a named graph. + .. deprecated:: + ``create_graph_snapshot_record()`` is deprecated and will be removed in + a future major version.

Remove the obsolete handler so those failures fall through to the generic handler, which reports "Failed to load from API: ..." and chains the real exception as ``__cause__``. Update the docstring's ``Raises`` section to match the actual behavior.

add_triplets skips flush (#970) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(triplet_store): OxigraphStore silently ignores storage_path and skips flush Two persistence bugs in OxigraphStore: 1. `storage_path=...` was silently swallowed by **config. The __init__ parameter is named `path`, so passing the project-conventional `storage_path` (used by ProvenanceManager and other stores) left self.path = None and the store silently degraded to in-memory — no error, no warning, data gone on exit. Accept `storage_path` as an alias for `path`. 2. add_triplets never called flush(). pyoxigraph auto-flushes via background threads but, per its docs, "might lag a little bit" — that lag is a race where reopening or crashing immediately after a write observes fewer triples. Call flush() explicitly for on-disk stores to close the window. Both verified: with the fix, `OxigraphStore(storage_path=...)` persists across reopen; without it, data is lost. * fix(triplet_store): improve oxigraph persistence * test(triplet_store): clarify oxigraph persistence test --------- Co-authored-by: administrator Co-authored-by: Sameer Kadam --- semantica/triplet_store/oxigraph_store.py | 59 +++++++++++++-- tests/triplet_store/test_oxigraph_store.py | 86 ++++++++++++++++++++++ 2 files changed, 138 insertions(+), 7 deletions(-) diff --git a/semantica/triplet_store/oxigraph_store.py b/semantica/triplet_store/oxigraph_store.py index 5262c00a..4ba94f03 100644 --- a/semantica/triplet_store/oxigraph_store.py +++ b/semantica/triplet_store/oxigraph_store.py @@ -42,6 +42,10 @@ class OxigraphStore: ProcessingError: If the store cannot be opened.

Move the helper into a sibling pure module, markdownUrlSafety.ts, following the existing GraphWorkspace convention for testable non-component logic (graphAnalytics.ts, pluginRegistryPredicates.ts, temporalLifecyclePredicates.ts). The function body is moved verbatim — the scheme allowlist, protocol-relative rejection, whitespace-only guard and malformed-URL handling are unchanged — so the existing URL-safety tests pass untouched apart from the import path. The component module now exports only its component and prop type, clearing the lint error without any change to the lint configuration.

Two findings, one of which is fixed here. 1. Every re-render re-parsed the whole document and remounted the whole subtree. remarkPlugins and the ~20-entry components map were inline literals, so each render allocated fresh arrow components; React saw a new element type per mapped tag and replaced the DOM rather than updating it. A DOM-identity probe confirmed the remount on every fixture. Because react-markdown runs the remark pipeline inside its own render, an unrelated state change -- clicking Copy, toggling Preview/Source -- re-paid the full parse. Measured 364ms for a 1000-row GFM table and 1121ms for 2000 rows. Hoisting both props to module scope and memoising the rendered element on rawContent drops re-render cost to ~0.1ms across every fixture and removes the remount (DOM identity now survives). Initial mount and node switching are unchanged, since those are genuine parses. 2. Initial parse of large GFM tables is quadratic and lives upstream in remark-gfm: the same table text parses in 12.5ms without the plugin and 1156ms with it at 2000 rows. Not addressed here -- any mitigation is a product decision and is tracked on the issue. Note that document size is the wrong threshold for this: 562KB of prose parses in 85ms while a 27KB GFM table takes 102ms. Row count, not bytes, predicts cost. Rendered output is unchanged; the components map is moved verbatim. All 66 Explorer graph-workspace tests pass.

The repository already contained a richer canonical regression file at tests/reproduce_issue_176.py (11 tests across three classes) which had the same naming problem: it was also never auto-discovered. The contributor's file added only TestMaxTokensPropagation (3 tests), which is a strict subset of what the canonical file already covers. No unique coverage is lost by removing it. Changes: - Rename tests/reproduce_issue_176.py -> tests/test_reproduce_issue_176.py so all 11 regression tests are collected by 'pytest tests/' - Remove tests/optimize reproduce_issue_176.py (redundant strict subset) No production code changes.

Pydantic strict validation rejects the float and the whole /api/decisions endpoint returns HTTP 422 "Invalid input", which breaks the Decisions workspace in the Knowledge Explorer entirely (no decision can be listed). Coerce the value to str (preserving None) in _node_to_decision so the response validates. Verified: /api/decisions now returns 200 and the 3 sample decisions render in the Decisions workspace. * test(explorer): cover decision timestamp coercion in _node_to_decision Regression tests for the 422 fix in _node_to_decision. Covers the cases that produced HTTP 422 (float / int timestamps from ContextGraph) and the ones that must keep working (None, already-string, missing key). Verified the suite catches the regression: with the fix reverted, the float / int / nan / inf cases fail with the same ValidationError that caused the 422; with the fix applied all 6 pass. * fix(explorer): preserve decision timestamp normalization The route-level str() cast introduced in the initial fix bypasses DecisionResponse._normalize_timestamp, the field validator on main that converts POSIX float epochs to ISO-8601 strings via datetime.fromtimestamp(value, tz=UTC).isoformat(). With the cast in place the API emits raw numeric strings such as '1786513069.69' instead of '2026-08-12T05:37:49+00:00', breaking datetime.fromisoformat() for every caller and failing TestRecordedDecisions::test_list_decisions_serializes_float_timestamp. It also silently accepts nan/inf/out-of-range epochs that the validator is designed to reject. Restore _node_to_decision() to pass the raw stored value through unchanged so DecisionResponse._normalize_timestamp remains the single normalization boundary for all three affected endpoints: GET /api/decisions GET /api/decisions/{id} GET /api/decisions/{id}/precedents Rewrite test_decision_route_timestamp.py so every assertion uses datetime.fromisoformat() to verify ISO-8601 output and explicitly asserts ValidationError for nan, inf, -inf and out-of-range epochs.

Drop the newer static helper added in #1148 and route all call sites through _escape_literal instead. Behaviour no-op. Closes #1218. * fix(export): handle datetime/None temporal bounds safely in OWL-Time _escape_literal is str-only, so routing datetime or None temporal bounds through it raised AttributeError during Turtle export. Stringify non-str bounds (plain f-string semantics) before escaping, and render None as an empty bound. Add regression tests for datetime bounds and end-only intervals. Addresses Qodo high-priority finding #2 on #1221. * fix(export): use isoformat for datetime temporal bounds str() on a datetime drops the ISO-8601 T separator, producing a lexically invalid xsd:dateTimeStamp. Use isoformat() when available; strengthen the test to assert the exact T-separated form. --------- --- semantica/export/rdf_exporter.py | 43 +++++++++-------- tests/export/test_owl_time_reachability.py | 56 ++++++++++++++++++++++ 2 files changed, 79 insertions(+), 20 deletions(-) diff --git a/semantica/export/rdf_exporter.py b/semantica/export/rdf_exporter.py index 68e28bd3..7a290b0c 100644 --- a/semantica/export/rdf_exporter.py +++ b/semantica/export/rdf_exporter.py @@ -193,6 +193,25 @@ def _escape_literal(value: str) -> str: ) +def _escape_temporal_literal(value: Any) -> str: + """Escape a temporal bound for a Turtle ``dateTimeStamp`` literal. + + Bounds are normally strings, but callers may hand us a ``datetime`` or + ``None``. ``_escape_literal`` is str-only, so stringify non-str values + first instead of calling ``.replace()`` on them; ``None`` yields an empty + bound rather than crashing.

<1829967558hsl@gmail.com> Date: Thu, 27 Aug 2026 00:11:07 +0800 Subject: [PATCH 092/102] fix(ontology): preserve #-terminated namespaces in SHACLGenerator base_uri (#1082) (#1084) * fix(ontology): preserve #-terminated namespaces in SHACLGenerator base_uri (#1082) SHACLGenerator.__init__ normalized base_uri with rstrip('/') + '/', turning a #-terminated RDF namespace (e.g. http://example.org/manufacturing#) into ...#/. Every generated URI then landed in a different namespace than the instance data, so SHACL validation silently passed because the shapes targeted nothing. __init__ now preserves a base_uri already ending in '/' or '#', matching the #-aware normalization generate() already applies. shapes_uri inherits the fix. Adds test_hash_namespace_base_uri_is_not_mangled (fails on the old normalization), plus a CHANGELOG entry. Full ontology suite green. Co-Authored-By: Claude * fix(ontology): collapse slash runs, only preserve #-terminated base_uri Qodo review caught that preserving any endswith('/') base left redundant trailing slashes (e.g. .../ns////) intact, leaking a different namespace into emitted IRIs. Now only '#'-terminated bases are kept verbatim; slash runs are collapsed to a single '/', matching generate() normalization. Adds test_slash_run_normalization_regression. --------- Co-authored-by: changshenhan <217217832+changshenhan@users.noreply.github.com> Co-authored-by: Claude --- CHANGELOG.md | 4 ++++ semantica/ontology/ontology_generator.py | 11 ++++++++++- tests/ontology/test_ontology_advanced.py | 21 +++++++++++++++++++++ 3 files changed, 35 insertions(+), 1 deletion(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index ffbaa7be..3910a3f6 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -132,6 +132,10 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 - 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 raised NameError, re-wrapped by their except handlers into a ProcessingError reading 'Failed to execute query: name text is not defined' -- a message that looks like a database fault rather than a missing import. No test exercised either method, so this also repairs a pre-existing failure in tests/ingest/test_notebook_02.py::test_08_database_ingestion. Add SQLite-backed coverage for all three call sites, including the SELECT COUNT(*) branch that only runs when no limit is passed and would otherwise stay untested. Closes #1015 * test(ingest): register setUp cleanups with addCleanup TemporaryDirectory and the SQLAlchemy engine were released only in tearDown, which unittest skips when setUp raises partway through. Register each cleanup as soon as its resource exists so a failed setUp still disposes the engine and removes the temp directory. LIFO ordering keeps dispose before cleanup, as tearDown had it. --------- Co-authored-by: Pravit Ampapathini Co-authored-by: Pravit Ampapathini --- semantica/ingest/db_ingestor.py | 2 + tests/ingest/test_db_ingestor_query.py | 112 +++++++++++++++++++++++++ 2 files changed, 114 insertions(+) create mode 100644 tests/ingest/test_db_ingestor_query.py diff --git a/semantica/ingest/db_ingestor.py b/semantica/ingest/db_ingestor.py index 351238d3..0d656dee 100644 --- a/semantica/ingest/db_ingestor.py +++ b/semantica/ingest/db_ingestor.py @@ -815,6 +815,8 @@ class DBIngestor: engine = connector.connect(connection_string) try: + from sqlalchemy import text + with engine.connect() as conn: # Execute query with parameters (parameterized queries for safety) result = conn.execute(text(query), params) diff --git a/tests/ingest/test_db_ingestor_query.py b/tests/ingest/test_db_ingestor_query.py new file mode 100644 index 00000000..4c2fcfa3 --- /dev/null +++ b/tests/ingest/test_db_ingestor_query.py @@ -0,0 +1,112 @@ +"""Query-execution coverage for DBIngestor and DataExporter. + +Regression tests for #1015: ``sqlalchemy.text`` was imported function-locally inside +``DatabaseConnector.connect()`` and ``DatabaseConnector.test_connection()``, but called +in ``DataExporter.export_table_data()`` and ``DBIngestor.execute_query()``, which never +imported it.

L1 - Action type system: - Action base class with execute(bindings, reasoner) + ?var substitution - AssertAction (optional write-back to KnowledgeGraph), RetractAction, CallAction (structured replacement for the unused Rule.handler), EmitEventAction (delivers to a registered event sink) - Rule.actions field; wired into Reasoner.forward_chain() and ReteEngine.execute_matches() (via optional bind_reasoner) L2 - Provenance-aware actions: - Reasoner records fired actions (rule, bindings, confidence) to action_log when provenance is enabled - Fix dangling import in reasoning_provenance.py (ReasoningEngine -> Reasoner, infer -> infer_facts) Backward compatible: rules using the legacy handler still fire (wrapped as a CallAction); rules without actions behave exactly as before. Adds tests/reasoning/test_rule_actions.py (9 tests). Closes #1095 * fix(reasoning): address qodo review findings on rule actions - Token-aware variable substitution to avoid ?x/?xy prefix collision - KnowledgeGraph write-back protocol (explicit API -> canonical translation -> ValueError) - Structured action_log entries with timestamp - Decouple action firing from conclusion dedup via per-activation tracking (fires known conclusions once; retract-self no longer loops to max_iterations) - Add Reasoner.infer_with_results preserving confidence; infer_facts delegates - Forward provenance flag in ReasoningProvenance; drop **kwargs; propagate confidence - Populate Rete Match.bindings from rule conditions - Add regression tests for each fix * fix(reasoning): persist fired action activations * fix(reasoning): deduplicate Rete action execution * fix(reasoning): canonicalize action activation identity * docs(reasoning): explain action replay controls --------- Co-authored-by: 江俊杰 --- docs/guides/reasoning.md | 13 + docs/reference/reasoning.md | 21 +- semantica/reasoning/__init__.py | 13 + semantica/reasoning/reasoner.py | 443 +++++++++++++++- semantica/reasoning/reasoning_provenance.py | 33 +- semantica/reasoning/rete_engine.py | 131 ++++- tests/reasoning/test_rule_actions.py | 531 ++++++++++++++++++++ 7 files changed, 1141 insertions(+), 44 deletions(-) create mode 100644 tests/reasoning/test_rule_actions.py diff --git a/docs/guides/reasoning.md b/docs/guides/reasoning.md index 4df1d010..dc9aa744 100644 --- a/docs/guides/reasoning.md +++ b/docs/guides/reasoning.md @@ -150,6 +150,12 @@ HighRiskSupplier(DELTA-3) conf=100% rule=Rule 3 DELTA-3 is flagged even though no document described it that way — the system traced: DELTA-3 supplied GAMMA-7, and GAMMA-7 exploits critical CVEs.
