Symfony AI bridges always advertise all capabilities, regardless of their ModelCatalog #41

Problem

SymfonyAiCompilerPass::process() always passes self::ALL_CAPABILITIES as the provider-level capabilities, even when a static ModelCatalog was read and modelCapabilities is populated. The docblock of ALL_CAPABILITIES says it should only be the fallback for bridges without a catalog.

Example: mittwald/symfony-ai-platform has no model with output-image, but the "Available providers" view lists "Image Generation" for it.

Effect beyond display

Models that map to no AiM capability (e.g. whisper-large-v3-turbo, TTS models) are not part of modelCapabilities, so AiProviderManifest::hasModelCapability() falls back to the provider-level list. Capabilities that no listed model has (e.g. Image Generation) are never detected as "specialized", so they are inherited:

$manifest->hasModelCapability('whisper-large-v3-turbo', ImageGenerationCapableInterface::class); // true

The ImageGenerationCapableInterface guard in hasModelCapability() only applies when modelCapabilities is empty.

Environment

• b13/aim 0.5.0
• TYPO3 14.3.7
• symfony/ai-platform 0.13.0
• mittwald/symfony-ai-platform 0.1.3
• PHP 8.5.2

Suggested fix

Derive the provider-level capabilities from the catalog when one exists:

$capabilities = $bridge['modelCapabilities'] !== []
    ? array_values(array_unique(array_merge(...array_values($bridge['modelCapabilities']))))
    : self::ALL_CAPABILITIES;
