Context

The aggregation layer uses concurrent API calls via errgroup. If the Gitea instance is unreachable (network partition, maintenance window), the app currently propagates a raw error to the handler and likely returns a 500 with no useful feedback.

The ROADMAP notes that in-memory cache with 30s TTL is the mitigation for rate limiting, but there is no UI-level fallback for total API unavailability.

What to do

  1. In each handler that calls the aggregation layer (GetTriageQueue, ListAllIssues, ListAllPullRequests), catch error responses and render a user-friendly error fragment instead of a blank/500 page.
  2. Create a reusable error.html partial template that shows:
    • A friendly message: "Could not reach Gitea. Check your token or try again."
    • A retry button using hx-get to reload the current view.
  3. For HTMX fragment requests (HX-Request: true), return just the error fragment (not a full page).
  4. Add a unit test confirming the error template is rendered when the client returns an error.

Acceptance Criteria

  • Dashboard, Issues, and PRs views display a friendly error message (not a 500) when Gitea API is unreachable
  • The error fragment includes a "Retry" button wired with HTMX
  • HTMX partial requests return only the fragment (no full page wrapper)
  • Unit test for error path in at least one handler
  • go test ./... passes

[Repo Manager Triage] Assigned to @AI-Engineer. P2 medium-scope feature to add graceful error UI when the Gitea API is unreachable. Independent of the merge PR feature chain (#187/#188/#186) so can be worked on in parallel.
