- Added functionality to automatically create inverse backlinks for intra-note edges at the chunk level, ensuring that backlinks are generated only when they do not already exist.
- Updated the documentation to outline the requirements and rules for backlink creation, including conditions for deduplication and scope.
- Introduced unit tests to validate the creation of backlinks and ensure correct behavior when existing backlinks are present.
- Incremented version to 4.4.0 to reflect the new feature addition.
- Introduced a new function `load_graph_schema_full` to parse and cache both typical and prohibited edge types from the graph schema.
- Updated `load_graph_schema` to utilize the full schema for improved edge type extraction.
- Added `get_topology_info` to retrieve typical and prohibited edges for source/target pairs.
- Implemented `validate_intra_note_edge` and `validate_edge_against_schema` for schema validation of intra-note edges.
- Enhanced logging for schema validation outcomes and edge handling.
- Updated documentation to reflect new validation features and testing procedures.
- Introduced configurable edge scoring with internal and external boosts for intra-note edges.
- Added aggregation configuration to support note-level and chunk-level retrieval strategies.
- Updated retriever and graph subgraph modules to utilize new scoring and aggregation logic.
- Enhanced YAML configuration to include new parameters for edge scoring and aggregation levels.
- Added boolean indexing for filtering based on edge properties in the setup script.
- Added a new function `_propagate_section_type_backwards` to ensure that the section_type is correctly assigned to all blocks within a heading section, even if the [!section] callout appears later in the text.
- Updated the `parse_blocks` function to call this new method, enhancing the accuracy of section-type assignments.
- Modified chunking strategies to reflect the changes in section-type handling, simplifying logic related to section-type transitions.
- Expanded unit tests to validate the backward propagation of section_type, ensuring comprehensive coverage of the new functionality.
- Modified the assertion in the test for edge types to include 'references' as a valid fallback option alongside 'foundation_for', 'guides', and 'related_to'.
- This change enhances the test coverage for edge type validation, ensuring more comprehensive checks for edge cases.
- Implemented WP-26 v1.1: Section-Type-Wechsel erzwingt Split auch in SMART MODE (Schritt 2) zur Verbesserung der Chunking-Logik.
- Updated `parse_link_target` to extract block IDs from section strings, ensuring accurate handling of links with block references.
- Added unit tests to validate section-type change behavior and block ID extraction functionality, enhancing overall reliability.
- Implemented WP-26 v1.1: Section-Type-Wechsel erzwingt immer einen neuen Chunk, um konsistente Chunking-Verhalten bei unterschiedlichen section_types zu gewährleisten.
- Introduced automatic Intra-Note-Edges zwischen Sektionen mit unterschiedlichen Typen, um semantische Beziehungen zu erfassen.
- Updated graph utilities to support automatic edge type derivation based on section transitions.
- Added unit tests for section-type changes and automatic edge generation to ensure functionality and reliability.
- Updated provenance priorities and introduced a mapping from internal provenance values to EdgeDTO-compliant literals.
- Added a new function `normalize_provenance` to standardize internal provenance strings.
- Enhanced the `_edge` function to include an `is_internal` flag and provenance normalization.
- Modified the `EdgeDTO` model to include a new `source_hint` field for detailed provenance information and an `is_internal` flag for intra-note edges.
- Reduced the provenance options in `EdgeDTO` to valid literals, improving data integrity.
