* fix: respect fileConfig.disabled for agents endpoint upload button
The isAgents check was OR'd without the !isUploadDisabled guard,
bypassing the fileConfig.endpoints.agents.disabled setting and
always rendering the attach file menu for agents.
* test: add regression tests for fileConfig.disabled upload guard
Cover the isUploadDisabled rendering gate for agents and assistants
endpoints, preventing silent reintroduction of the bypass bug.
* test: cover disabled fallback chain in useAgentFileConfig
Verify agents-disabled propagates when no provider is set,
when provider has no specific config (agents as fallback),
and that provider-specific enabled overrides agents disabled.
* chore: Remove unused setValueOnChange prop from MCPServerMenuItem component
* fix: Resolve agent provider endpoint type for file upload support
When using the agents endpoint with a custom provider (e.g., Moonshot),
the endpointType was resolving to "agents" instead of the provider's
actual type ("custom"), causing "Upload to Provider" to not appear in
the file attach menu.
Adds `resolveEndpointType` utility in data-provider that follows the
chain: endpoint (if not agents) → agent.provider → agents. Applied
consistently across AttachFileChat, DragDropContext, useDragHelpers,
and AgentPanel file components (FileContext, FileSearch, Code/Files).
* refactor: Extract useAgentFileConfig hook, restore deleted tests, fix review findings
- Extract shared provider resolution logic into useAgentFileConfig hook
(Finding #2: DRY violation across FileContext, FileSearch, Code/Files)
- Restore 18 deleted test cases in AttachFileMenu.spec.tsx covering
agent capabilities, SharePoint, edge cases, and button state
(Finding #1: accidental test deletion)
- Wrap fileConfigEndpoint in useMemo in AttachFileChat (Finding #3)
- Fix misleading test name in AgentFileConfig.spec.tsx (Finding #4)
- Fix import order in FileSearch.tsx, FileContext.tsx, Code/Files.tsx (Finding #5)
- Add comment about cache gap in useDragHelpers (Finding #6)
- Clarify resolveEndpointType JSDoc (Finding #7)
* refactor: Memoize Footer component for performance optimization
- Converted Footer component to a memoized version to prevent unnecessary re-renders.
- Improved import structure by adding memo to the React import statement for clarity.
* chore: Fix remaining review nits
- Widen useAgentFileConfig return type to EModelEndpoint | string
- Fix import order in FileContext.tsx and FileSearch.tsx
- Remove dead endpointType param from setupMocks in AttachFileMenu test
* fix: Pass resolved provider endpoint to file upload validation
AgentPanel file components (FileContext, FileSearch, Code/Files) were
hardcoding endpointOverride to "agents", causing both client-side
validation (file limits, MIME types) and server-side validation to
use the agents config instead of the provider-specific config.
Adds endpointTypeOverride to UseFileHandling params so endpoint and
endpointType can be set independently. Components now pass the
resolved provider name and type from useAgentFileConfig, so the full
fallback chain (provider → custom → agents → default) applies to
file upload validation on both client and server.
* test: Verify any custom endpoint is document-supported regardless of name
Adds parameterized tests with arbitrary endpoint names (spaces, hyphens,
colons, etc.) confirming that all custom endpoints resolve to
document-supported through resolveEndpointType, both as direct
endpoints and as agent providers.
* fix: Use || for provider fallback, test endpointOverride wiring
- Change providerValue ?? to providerValue || so empty string is
treated as "no provider" consistently with resolveEndpointType
- Add wiring tests to CodeFiles, FileContext, FileSearch verifying
endpointOverride and endpointTypeOverride are passed correctly
- Update endpointOverride JSDoc to document endpointType fallback
