Reviewer's GuideLinter-driven cleanup across backend, tests, scripts, and notebooks plus targeted security/middleware fixes: refactors trusted-proxy IP extraction to be injectable and correctly indexed, standardizes logging/printing and imports, and tightens proxy-related tests so rate limiting and X-Forwarded-For handling are robust and testable.

Hey - I've found 2 issues, and left some high level feedback:
- The change in
extract_client_ip_from_forwarded’strusted_proxy_countsemantics (usingidx = -trusted_proxy_countinstead of-(trusted_proxy_count + 1)) is non-trivial; consider adding an explicit docstring example or comment describing the expected X-Forwarded-For layout for different counts so future callers don’t misinterpret it. - Several tests now patch
agent.security.TRUSTED_PROXIESandTRUSTED_PROXY_COUNTinline; you might want to centralize this into a reusable fixture or helper to avoid duplication and keep proxy-related test configuration consistent.

Please address the comments from this code review:
## Overall Comments
- The change in `extract_client_ip_from_forwarded`’s `trusted_proxy_count` semantics (using `idx = -trusted_proxy_count` instead of `-(trusted_proxy_count + 1)`) is non-trivial; consider adding an explicit docstring example or comment describing the expected X-Forwarded-For layout for different counts so future callers don’t misinterpret it.
- Several tests now patch `agent.security.TRUSTED_PROXIES` and `TRUSTED_PROXY_COUNT` inline; you might want to centralize this into a reusable fixture or helper to avoid duplication and keep proxy-related test configuration consistent.

+ # The proxy appends the socket.peername.
+ # So the real client IP is the LAST element (ips[-1]) if TPC=1.

<issue_to_address>
**issue (bug_risk):** The updated trusted_proxy_count index logic appears inverted and may return a proxy IP instead of the real client IP.
Previously we used `idx = -(trusted_proxy_count + 1)`, which matches X-Forwarded-For semantics: for `[client, proxy1, proxy2]` and `trusted_proxy_count = 1`, `ips[-2]` correctly returns `client` (the element before the trusted proxy). With the new `idx = -trusted_proxy_count`, the same case returns `ips[-1]` (the trusted proxy), contradicting the comment and prior behavior, and causing the proxy IP to be treated as the client IP. Please either restore `idx = -(trusted_proxy_count + 1)` or explicitly change the semantics/docs of `trusted_proxy_count` to keep returning the real client IP.

**suggestion (testing):** Add focused unit tests for `extract_client_ip_from_forwarded` to cover new `trusted_proxies` and `trusted_proxy_count` parameters
These tests still only cover the global `TRUSTED_PROXIES` / `TRUSTED_PROXY_COUNT` config via patches. To properly exercise the new function-level arguments and security logic, add targeted unit tests that call `extract_client_ip_from_forwarded` directly, e.g.:
- `trusted_proxies` non-empty with `trusted_proxy_count=None` (right-to-left skipping of trusted proxies).
- `trusted_proxies=None` with `trusted_proxy_count > 0` (verify `idx = -trusted_proxy_count` for various list lengths).
- Edge cases: all IPs trusted, empty header, single IP with non-zero count, malformed IPs with fallback.
These will better validate the new extraction behavior beyond the middleware integration tests.

- Line 9: Remove the unused import symbol pkg_resources from the top of the
visualize_dependencies.py module; locate the import statement "import
pkg_resources" and delete it (no other code references to pkg_resources need
changes) so the file no longer includes an unused import.
In `@backend/tests/test_configuration.py`:
- Around line 10-16: Remove the unused TEST_MODEL import from the agent.models
import block in backend/tests/test_configuration.py; update the import list to
only include DEFAULT_ANSWER_MODEL, DEFAULT_QUERY_MODEL,
DEFAULT_REFLECTION_MODEL, and GEMINI_PRO, keeping the alphabetical ordering and

In `@backend/tests/test_graph_mock.py`:
- Around line 6-15: Remove the unused TEST_MODEL symbol: delete the import "from
agent.models import TEST_MODEL" and the local reassignment TEST_MODEL =
"gemma-3-27b-it" in test_graph_mock.py since TEST_MODEL is never referenced;
leaving these lines creates dead code and shadowing — simply remove both the
import and the local constant.
In `@backend/tests/test_nodes.py`:
- Around line 16-38: The test file imports an unused symbol OverallState from
agent.state; remove the unused import to clean up imports and avoid linter/test
warnings. Locate the import list where OverallState is referenced and delete
that token (the import of OverallState) so the file only imports actually used
names like content_reader, denoising_refiner, etc.
In `@backend/tests/test_proxy_security.py`:
- Around line 88-89: The test patches TRUSTED_PROXIES to an empty set which
prevents extract_client_ip_from_forwarded() from exercising the right-to-left
trusted-proxy branch and therefore doesn't validate _is_ip_in_trusted_proxies()
or the trusted-proxy list logic; update the test_spoofing_vulnerability() setup
to patch TRUSTED_PROXIES to a non-empty set containing at least one
known-trusted IP (and keep TRUSTED_PROXY_COUNT as needed) so the right-to-left
branch is exercised, or alternatively rename the test to indicate it only
validates count-based extraction if you intend to keep TRUSTED_PROXIES empty.

Inline comments:
In `@backend/examples/kaggle_integration.py`:
- Around line 198-205: The safe evaluator's operators mapping incorrectly uses
ast.UnaryOp as a key causing KeyError for unary expressions; update the
operators dict (used by the evaluator that dispatches with type(node.op)) to map
ast.USub to op.neg and ast.UAdd to op.pos (i.e., replace the ast.UnaryOp entry
with ast.USub: op.neg and add ast.UAdd: op.pos) so unary -/+ are resolved
correctly when evaluating nodes.
In `@backend/scripts/benchmark.py`:
- Around line 134-136: The logger.info call is printing raw benchmark prompts
via the question variable; replace that with a stable identifier (e.g., the loop
index or a deterministic hash of question) so logs do not contain full prompt
text, and keep the full question only in the report payload (where result_entry
is assembled). Update the logger.info invocation that references question and
result_entry to log the chosen id/hash and the quality/groundedness scores, and
ensure the complete question remains stored in the report payload structure but
is not written to logs.
- Around line 78-84: Replace the tuple-based message with an explicit
HumanMessage: in the graph.ainvoke call use a list containing
HumanMessage(content=question) instead of [("user", question)], and add the
module-scope import from langchain_core.messages: import HumanMessage so the
symbol is available; update the call site in the benchmark.py snippet that calls
graph.ainvoke accordingly.
In `@backend/tests/test_mcp_tools.py`:
- Line 1: Remove the unused import statement for asyncio at the top of the test
file; locate the line that reads "import asyncio" in
backend/tests/test_mcp_tools.py and delete it so no unused imports remain (tests
already use async/await and pytest.mark.asyncio and don't require asyncio).
In `@backend/tests/test_persistence.py`:
- Around line 7-8: Remove the unused imports `json` and `os` from the test file
so there are no unused imports in backend/tests/test_persistence.py; locate the
import statement that declares `import json` and `import os` at the top of the
file (near other imports) and delete those two symbols from the file’s import
list.
In `@backend/tests/test_validation_coverage.py`:
- Line 2: Remove the unused import "logging" from the test file; the tests use
the pytest "caplog" fixture and do not need a direct logging import, so delete
the line importing logging to eliminate the unused import warning.
In `@scripts/update_models.py`:
- Around line 158-160: The regex in the update_file call currently only matches
r'(model=\" )gemini-[^"]+(\" )' so once a cell is updated to a different prefix
(e.g., gemma) it won't match again; change the pattern used in update_file to
capture any model string (e.g., r'(model=\"")[^"]+(\"') so it replaces the full
model value generically, and update the replacement to use the captured prefix
and suffix with config['answer'] (keep the same update_file call and the use of
config['answer'] so only the inner model value is swapped).

total length reflects deduplication; apply the same duplicate-case addition to

44-53: Rename the injected patch mock to snake_case.
MockLLMreads like a class name and is the remaining Python naming-style warning in this changed test. Renaming it to something likemock_llmormock_llm_clskeeps the test idiomatic and aligned with the repo’s linting expectations.♻️ Proposed cleanup

34-49: Pre-parse trusted proxy entries instead of reparsing them on each request.This helper rebuilds
ip_network/ip_addressobjects for every candidate IP, which keeps the hot path heavier than it needs to be and is a big part of the complexity Sonar flagged.

- Around line 73-75: Update the helper docstrings to match the new function
signature and the corrected indexing rule: add documentation for the new
trusted_proxies parameter alongside trusted_proxy_count and fallback_ip, and
change any description that says ips[-(trusted_proxy_count + 1)] to the correct
ips[-trusted_proxy_count] indexing. Make these edits in the docstring
immediately above the function that declares trusted_proxy_count,
trusted_proxies, and fallback_ip and in the other docstring block that
references TRUSTED_PROXY_COUNT (the second occurrence around the later helper
description), ensuring the parameter list and examples reflect the new behavior.

There was a problem hiding this comment.
Update the helper docs to match the new signature and indexing rule.
trusted_proxies was added to the signature, but the docstring still omits it, and the method overview above still describes ips[-(trusted_proxy_count + 1)] while this branch now uses ips[-trusted_proxy_count]. In this code path, stale docs make TRUSTED_PROXY_COUNT easy to misread and misconfigure.
Also applies to: 139-145
