configured Web evidence tool

Error message

configured Web evidence tool

What it means

A panic from `.expect("configured Web evidence tool")` in the test `small_surface_read_only_child_discovers_web_deferred`. The test searches the deferred catalog for a Scout-role child and asserts a tool named "Web" exists with `defer_loading == Some(true)`; if the configured small-surface profile no longer registers a Web evidence tool, `find` returns `None` and the expect panics. This is a configuration/contract drift between the test fixture and the tool surface configuration.

Solutions

1. Inspect `small_surface_registry(FleetRole::Scout)` and the profile's tool list to confirm a `Web` tool is registered for Scout
2. Print the catalog (`dbg!(&catalog.iter().map(|t| t.name.clone()).collect::<Vec<_>>())`) to see which tools actually exist
3. Update the test's expected tool name if the Web tool was intentionally renamed, or restore the Web registration in the Scout profile if the removal was accidental

Example fix

// before
.find(|tool| tool.name == "Web")
.expect("configured Web evidence tool");
// after (if renamed)
.find(|tool| tool.name == "WebSearch")
.expect("configured WebSearch evidence tool");

let web = catalog.iter().find(|t| t.name == "Web");
if web.is_none() {
    panic!("Web tool missing from Scout catalog; available: {:?}",
        catalog.iter().map(|t| t.name.as_str()).collect::<Vec<_>>());
}

fn find_tool<'a>(catalog: &'a [Tool], name: &str) -> Option<&'a Tool> {
    catalog.iter().find(|t| t.name == name)
}

let web = match catalog.iter().find(|t| t.name == "Web") {
    Some(t) => t,
    None => panic!("configured Web evidence tool missing from Scout catalog"),
};

When it happens

Trigger: The Scout small-surface profile stops including a tool named `Web` (renamed tool, changed `small_surface_registry`, or filtering in `deferred_catalog_for_model` removes it), so `catalog.iter().find(|t| t.name == "Web")` yields `None`.

Common situations: A developer renames or relocates the Web tool in the tool catalog; profile changes exclude Web from read-only children; tool-name case changes (e.g. `web_search`) without updating this assertion.
