Moves all submodules from examples/ and notebooks from notebooks/ into their corresponding paths under the backend/ directory (backend/examples/ and backend/notebooks/). Updates all references in documentation (e.g., README.md, docs/) to point to the new paths while keeping all existing content, satisfying the architectural structure documented in visualization examples.

Summary by Sourcery

Update documentation references to reflect relocation of examples and notebooks into the backend directory hierarchy.

Documentation:

  • Adjust docs to reference example modules under backend/examples instead of examples.
  • Update documentation to point to notebooks under backend/notebooks instead of notebooks/.

Moves all submodules from `examples/` and notebooks from `notebooks/` into their corresponding paths under the `backend/` directory (`backend/examples/` and `backend/notebooks/`). Updates all references in documentation (e.g., `README.md`, `docs/`) to point to the new paths while keeping all existing content, satisfying the architectural structure documented in visualization examples.

Walkthrough

Updated docs to reference backend/ notebook paths. Many Jupyter notebooks updated their Colab/environment setup, path discovery, and sys.path append logic; several user-facing print strings changed (emoji/plain literals). One notebook renamed a parameter; Search_Tool_Comparison extracted two helper functions for result/error row construction. No public/exported APIs were added or removed.

Changes

Cohort / File(s) Summary
Documentation path updates
docs/IMPLEMENTATION_SUMMARY.md, docs/TEST_COVERAGE_PLAN.md, docs/memory_consolidation.md
Adjusted documented notebook/example paths to backend/notebooks/ and backend/examples/; marked two examples as (Archived) and added refine_draft_report.
Notebook environment/bootstrap changes
backend/notebooks/... (01_Agent_Deep_Research.ipynb, 02_MCP_Tools_Integration.ipynb, 03_Benchmarking_Pipeline.ipynb, 04_SOTA_Comparison.ipynb, agent_architecture_demo.ipynb, colab_setup.ipynb, deep_research_demo.ipynb, test-agent.ipynb, 01_SOTA_Architecture_Comparison.ipynb, Deep_Research_Framework_Comparison.ipynb, 01_Agent_Deep_Research.ipynb, 02_SOTA_Workflow_Analysis.ipynb, ...)
Refined backend discovery to special-case backend/notebooks, tightened src sys.path append to check existence+membership, added editable-install branch when running from backend/notebooks (pip install -e ..), and standardized some emoji/plain-string prints. Several notebooks had EOF newline normalization.
Search result refactor
backend/notebooks/Search_Tool_Comparison.ipynb
Extracted process_single_result(res, domain, query, provider_name, i) and process_provider_error(e, domain, query, provider_name); compare_search_results now delegates row/error construction to these helpers; also adjusted model-verification/status text.
Minor API/identifier edits
backend/notebooks/02_SOTA_Workflow_Analysis.ipynb, backend/notebooks/Deep_Research_Framework_Comparison.ipynb
Renamed MockLLM.generate(prompt → _prompt) and MockLLM.synthesize(critiques → _critiques) (signature-only), and renamed class MockTTD_DRMockTtdDr in one notebook (not a repository-level exported API change).
Import ordering change
backend/src/agent/nodes.py
Moved from pathlib import Path import location; no behavioral change.
Formatting / messaging adjustments
backend/notebooks/... (many notebooks)
Replaced non-interpolating f-strings with plain literals for static messages, changed emoji glyphs in prints, and removed/added trailing newlines in some notebook files.

The specific path update in this file is correct, but verification revealed outdated references in other documentation files.

The notebook path reference in memory_consolidation.md has been appropriately updated to backend/notebooks/. However, the verification check found 10+ remaining outdated references across the documentation that still reference old paths without the backend/ prefix:

  • docs/PR19_CONFLICT_RESOLUTION.mdnotebooks/*.ipynb
  • docs/RESEARCH_INSPIRATIONS.mdexamples/cli_research.py (2 references)
  • docs/MERGE_ANALYSIS.mdexamples/ (2 references)
  • docs/OPTIMIZED_MODEL_CONFIG.mdexamples/cli_research.py
  • docs/ARCHITECTURE_INVENTORY.mdexamples/cli_research.py (4 references)
  • docs/GEMMA_CONFIG.mdexamples/cli_research.py

Consider updating these remaining references to use the new backend/ directory structure for consistency.

… fix CI

Moves all submodules from `examples/` and notebooks from `notebooks/` into their corresponding paths under the `backend/` directory (`backend/examples/` and `backend/notebooks/`). Updates all references in documentation (e.g., `README.md`, `docs/`) to point to the new paths while keeping all existing content.

Also resolves SonarCloud CI failures:
- Removes empty f-strings across all 12 notebooks.
- Renames unused `prompt` parameter to `_prompt` in `02_SOTA_Workflow_Analysis.ipynb`.
- Refactors `compare_search_results` in `Search_Tool_Comparison.ipynb` into smaller helper functions to reduce cognitive complexity.

⚠️ Potential issue | 🟠 Major

Guard helper logic against nullable provider fields.

Line 246 and Line 258 assume res.content is always a string. If a provider returns None, this raises at helper level and Line 294 drops into provider-level error handling for that query/provider path.

 def process_single_result(res, domain, query, provider_name, i):
-    has_highlight = False
-    if "<b>" in res.content or "<strong>" in res.content:

Fixes GitHub Actions `actions/checkout` failure caused by inaccessible submodules (`gemma-cookbook`, `open_deep_research_example`, `thinkdepthai_deep_research_example`) by completely removing them from git tracking, as their upstream repositories have become private or changed permissions.

Also runs `ruff check --fix` in `backend/src/` to resolve the unsorted imports error in `backend/src/agent/nodes.py`. Updates documentation to mark the old submodules as (Archived).

Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>
Updates the `setup_environment()` logic inside all notebooks to correctly resolve the `backend_dir` path now that the notebooks reside in `backend/notebooks/` instead of `notebooks/`. This ensures the `agent` module is correctly imported during execution.

Also fixes remaining SonarCloud quality gate issues:
- Replaces `"release date of GPT-6"` duplication with a constant `QUERY_TEXT` in `01_SOTA_Architecture_Comparison.ipynb`.
- Fixes the `MockTTD_DR` class name to `MockTtdDr`.
- Replaces `dict()` and `list()` constructors with `{}` and `[]` literals in `Deep_Research_Framework_Comparison.ipynb`.
- Flattens nested IF blocks in the setup environment cells.
- Renames unused `prompt` and `critiques` parameters in `MockLLM` to `_prompt` and `_critiques` in `02_SOTA_Workflow_Analysis.ipynb`.
- Converts the remaining empty f-strings (like `f"  [OK] Model verification successful!"`) to normal strings across all notebooks.

Colab is still anchored to the old notebook folder.

target_dir is still built from <repo>/notebooks, so after this move the fallback to repo root becomes the normal path and the new backend/notebooks install branch never runs. That leaves the notebook depending on incidental state instead of actually executing from its new location.

📁 Suggested path fix

70-95: ⚠️ Potential issue | 🟡 Minor

This Colab bootstrap still resolves to the pre-move notebook path.

Because target_dir still points at <repo>/notebooks, the repo-root fallback is now the normal path and the new backend/notebooks install branch never runs. The MCP demo then executes from the wrong base directory, so relative paths like ./mcp_sandbox land somewhere different than the notebook now implies.

⚠️ Potential issue | 🟠 Major

Validate resolved backend_dir before using it for editable install.

If none of these branches match a real backend package, backend_dir stays as the current working directory and later pip install -e <cwd> can fail hard. Add an explicit validity check (src/ + pyproject.toml) before proceeding.

Note

Autofix is a beta feature. Expect some limitations and changes as we gather feedback and continue to improve it.

⚠️ Branch updated during autofix.

The branch was updated while autofix was in progress. Please try again.

Addresses the CI/SonarCloud failures caused by moving the `notebooks` and `examples` directories to `backend/notebooks/` and `backend/examples/`, removing the inaccessible git submodules, and sorting imports in `nodes.py`.

In addition, it updates `AGENTS.md` and `docs/memory_consolidation.md` to instruct agents on how to handle configuration files (like Dependabot and Mergify) that appear to be "missing". Agents are now explicitly told to verify the state of `main` via `git fetch` and check open PRs via `gh pr list` before assuming a file was deleted or recreating it, preventing them from overwriting configs added to `main` after their working branch was created.

Jules Session Analysis: This PR has merge conflicts. Recommended fix: git fetch origin && git rebase origin/main. Resolve conflicts and push. Let me know if you need help!

Resolved merge conflicts by accepting main's version for all conflicted files.
The main branch had more comprehensive content for most files including:
- Jules workflow templates and configurations
- Comprehensive .gitignore files
- Agent test files with full implementations
- Documentation files

This merge brings in the latest changes from main while preserving
the PR's intent to consolidate examples and notebooks to backend directory.
