Important

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (2)

• poetry.lock is excluded by !**/*.lock, !**/*.lock
• uv.lock is excluded by !**/*.lock, !**/*.lock

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

Walkthrough

Removes autosave from Notebook and expands result rendering to support graphs and datasets. Adjusts backend search to include graphs via new insights/context transformations. Updates default search last_k to 1. Refines timestamp model defaults/descriptions. Minor Ollama embedding payload formatting change. Tests updated for CLI mocks and relaxed temporal graph assertions.

Changes

Cohort / File(s)	Summary
Frontend Notebook API & rendering cognee-frontend/src/ui/elements/Notebook/Notebook.tsx	Removed saveNotebook prop and autosave logic; simplified props. On empty notebooks, auto-create and open first cell. Major CellResult refactor to support insights triplets and multiple graphs/datasets; added graph data transformations and richer fallbacks/error display.
Search API default cognee/api/v1/search/search.py	Changed search() default parameter last_k from None to 1. No other logic changes.
Embedding engine formatting cognee/infrastructure/databases/vector/embeddings/OllamaEmbeddingEngine.py	Reformatted request payload construction to a single-line dict; behavior unchanged.
Search methods integration cognee/modules/search/methods/search.py	Integrated prepare_search_result for per-item processing; now returns graphs alongside results; variable cleanup in combined-context branch. No signature changes.
Search utils: preparation & transforms cognee/modules/search/utils/prepare_search_result.py, cognee/modules/search/utils/transform_context_to_graph.py, cognee/modules/search/utils/transform_insights_to_graph.py	Added transform_insights_to_graph (new file). prepare_search_result now builds dataset-aggregated graphs/contexts, handles insights triplets, and conditionally returns graph or single-item results. transform_context_to_graph adjusts node1 attributes source.
Temporal models cognee/tasks/temporal_graph/models.py	Timestamp fields now include descriptions; month/day default 1; hour/minute/second default 0 (were required before).
Tests: CLI cognee/tests/cli_tests/cli_unit_tests/test_cli_main.py	Tightened MagicMock usage by adding spec={} to mocks; no behavioral changes.
Tests: temporal graph cognee/tests/test_temporal_graph.py	Relaxed count thresholds; removed interval and before/after checks; simplified between query assertions.

Poem

I nibbled the code and trimmed autosave,
Hopped through graphs, where insights behave.
With last_k set, the trail is neat,
Timestamps tidy, defaults complete.
Now datasets bloom in verdant arrays—
A rabbit’s graph, in luminous rays. 🐇📈

Pre-merge checks and finishing touches

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Description Check	⚠️ Warning	The PR description contains only the unfilled repository pull-request template and therefore lacks a human-written Description, a selected Type of Change, a concrete "Changes Made" list, testing details, and a completed Pre-submission Checklist; the template explicitly forbids AI-generated descriptions but no human content was provided. Because the required contextual information is missing, reviewers cannot assess the intent, scope, or testing of the changes included in this merge. The description is therefore largely incomplete and does not meet the repository's required template.	Do not merge until the author replaces the template with a human-written description that summarizes the PR purpose and high-level changes, selects the appropriate "Type of Change", enumerates specific changes and affected files, describes how the changes were tested (including results), completes the Pre-submission Checklist, links any related issues, and affirms the DCO; include screenshots or test output if helpful and ensure the description is not AI-generated as required by the template. After these updates are provided, request re-review.

✅ Passed checks (2 passed)

Check name	Status	Explanation
Title Check	✅ Passed	The title "Merge dev into main" accurately describes the branch-level action and is directly related to the changeset (a merge from dev into main); it is concise and unambiguous. It is somewhat generic and does not summarize the primary functional changes introduced by the merge (for example Notebook API changes, insights graph rendering, and search/default updates). Given the guidance, the title is acceptable but could be more informative to help reviewers quickly identify the main impacts.
Docstring Coverage	✅ Passed	Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%.
