# Brave Search

Web search validates the HTTP-success payload before normalizing results:

`web` must be an object and `results` a list when present and non-null.

Reject wrong container types with the shared structured format error, including

falsy values. Skip non-object entries while preserving valid objects in order;

an entirely malformed non-empty list is a format error, not an empty search.

Missing/null containers and an empty results list keep "No results found".

Preserve existing field defaults, query/count parameters, and image-search behavior.

Log the malformed container's path and type, or that no result objects remain,

before returning a format error. Keep queries, credentials, and payload values

out of these diagnostics; ordinary missing/empty results are not format errors.

`tests/test_brave_response_shapes.py` exercises the real tool and `_brave_get`

through an offline HTTPX transport with synthetic JSON bodies. Do not mock the

normalizer or substitute its final output. Patch the provider's `httpx` reference

with a local client factory and `HTTPStatusError`; never replace the shared

`httpx.Client`. Cover both the unchanged global client and HTTP error handling.
