PR #2178 added an 'allowOllamaFormat' guard (resolves to false for non-ollama
@-provider prefixes like '@custom:ai_gateway') to stop the ollama label
formatter from reformatting custom-provider model IDs with dashes. The
existing test asserted on the pre-PR code shape and didn't pick up the new
guard.
Updated the assertion to match the actual post-PR code at static/ui.js:2202,
with an extended docstring explaining the bug class the guard fixes (bare
custom-provider model IDs like 'Qwen3.6-35B-A3B' had hyphens stripped to
spaces + last letter lowercased by the formatter).
Surfaces providers added via credential_pool in the model dropdown. Ambient gh-cli tokens suppressed. _apply_provider_prefix helper extracted. Ollama Cloud display name + dynamic model list. looksLikeBareOllamaId heuristic tightened. Test isolation fixed.
