Summary

Issue #190 tracks inline expansion of triage cards on the dashboard. For that to work, the detail handlers must detect the HX-Request: true header and return only the content fragment (no layout wrapper) rather than a full page.

Currently IssueDetail and PullDetail in internal/handlers/handlers.go always call renderPage(), which wraps the content in the full layout. They do not branch on isHTMX(r) for the detail view.

What to do

  • In IssueDetail handler: after building the content HTML, check isHTMX(r). If true, write only the content HTML directly with w.Header().Set("Content-Type", "text/html") and fmt.Fprint(w, buf.String()). Otherwise call renderPage() as today.
  • Apply the same change to PullDetail handler.
  • The dashboard triage card hx-get call (from #190) will trigger with HX-Request: true, receiving only the fragment to swap inline.
  • Add a unit test in handlers_test.go that issues a GET to each detail route with the HX-Request: true header and asserts the response does NOT contain the layout boilerplate (e.g. no <nav class="bottom-nav">)

Acceptance Criteria

  • GET /issues/{owner}/{repo}/{index} with HX-Request: true returns a content fragment only (no <nav>, no <header>, no <html> wrapper)
  • GET /pulls/{owner}/{repo}/{index} with HX-Request: true returns a content fragment only
  • Both routes still return full-page HTML when HX-Request header is absent
  • Unit tests pass for both fragment and full-page responses

## Summary Issue #190 tracks inline expansion of triage cards on the dashboard. For that to work, the detail handlers must detect the `HX-Request: true` header and return only the content fragment (no layout wrapper) rather than a full page. Currently `IssueDetail` and `PullDetail` in `internal/handlers/handlers.go` always call `renderPage()`, which wraps the content in the full layout. They do not branch on `isHTMX(r)` for the detail view. ## What to do - In `IssueDetail` handler: after building the content HTML, check `isHTMX(r)`. If true, write only the content HTML directly with `w.Header().Set("Content-Type", "text/html")` and `fmt.Fprint(w, buf.String())`. Otherwise call `renderPage()` as today. - Apply the same change to `PullDetail` handler. - The dashboard triage card `hx-get` call (from #190) will trigger with `HX-Request: true`, receiving only the fragment to swap inline. - Add a unit test in `handlers_test.go` that issues a GET to each detail route with the `HX-Request: true` header and asserts the response does NOT contain the layout boilerplate (e.g. no `<nav class="bottom-nav">`) ## Acceptance Criteria - [ ] `GET /issues/{owner}/{repo}/{index}` with `HX-Request: true` returns a content fragment only (no `<nav>`, no `<header>`, no `<html>` wrapper) - [ ] `GET /pulls/{owner}/{repo}/{index}` with `HX-Request: true` returns a content fragment only - [ ] Both routes still return full-page HTML when `HX-Request` header is absent - [ ] Unit tests pass for both fragment and full-page responses ## References - Issue #190 (inline HTMX card expansion on dashboard) - ROADMAP.md Phase 2.2 — Dashboard/Triage: "Tap to expand inline via HTMX hx-get loading a detail fragment" - ROADMAP.md Phase 1.5 — HTTP Handlers: "Each handler checks the HX-Request header to decide whether to return a full page or an HTMX HTML fragment"

Triage: Assigned to @developer. When HX-Request header is present on GET /issues/{owner}/{repo}/{index} and GET /pulls/{owner}/{repo}/{index}, return only the HTMX content fragment instead of the full page. The renderPage() function already handles this for other routes -- verify the detail templates also support the content named template block correctly. No dependencies. Priority: P1.

Sprint planning update (2026-04-20): This is already implemented. The renderPage() function in internal/handlers/handlers.go (lines ~191-197) checks isHTMX(r) and returns just the content string when HX-Request: true is present, skipping the full layout wrapper. Both IssueDetail and PullDetail call renderPage(), so they already return HTMX fragments when the header is set.

The unit test for this behavior (asserting no <nav> in HTMX response) could still be added, but the functional implementation is done. The test is covered as part of #190 acceptance criteria. Closing as implemented.
