Error message

resolved

What it means

In `merge_order_is_user_override_then_provider_then_bundled`, `merged.resolve("sample/model").expect("resolved")` panics when the merged catalog has no entry for the model id. Since the test just inserted the id into `override_entries` and called `MergedCatalog::from_sources`, the panic means merge/precedence logic dropped the user-override entry.

Solutions

1. Verify the override entries map passed to `from_sources` actually contains the exact id being resolved
2. Check id normalization in `resolve` vs the inserted key (string equality vs normalized)
3. Inspect `from_sources` layering so user overrides are always retained in the merged map
4. Print `merged.entries` keys before resolve to see what survived the merge

Example fix

// before
let resolved = merged.resolve("sample/model").expect("resolved");
// after
let resolved = merged.resolve("sample/model")
    .unwrap_or_else(|| panic!("resolve failed; keys={:?}", merged.entries.keys().collect::<Vec<_>>()));

assert!(merged.entries.contains_key("sample/model"), "override entry lost in merge: {:?}", merged.entries.keys().collect::<Vec<_>>());

let resolved = merged.resolve("sample/model")
    .unwrap_or_else(|| panic!("resolve failed; merged keys: {:?}", merged.entries.keys().collect::<Vec<_>>()));

When it happens

Trigger: `MergedCatalog::from_sources` failing to include the override layer, or `resolve` looking up by a normalized id that differs from the inserted `"sample/model"` key; also occurs if `from_sources` is passed layers in an order that discards rather than overrides.

Common situations: Refactoring merge precedence in `model_catalog.rs`; changing model-id normalization (case, provider prefix) so the inserted key no longer matches the lookup key; switching from BTreeMap overlay to a replace-last-wins merge.
