TODO: remove the old server-rendered layout/page path

The note page now renders through defaulttemplate (defaulttemplate.WriteRender).
Several older server-rendered cases and templates are partially or fully
superseded. This doc records what can be removed, what must stay, and the
cascade for each — so the cleanup can be done later as its own change.

Status: step 1 (rendersearchpage) DONE in PR #176 (2026-07-11), which also
unblocks step 2. Steps 2-4 still pending. Verify each remaining "candidate"
against live traffic / external links before deleting.

Verdicts

Target Verdict Why
internal/case/rendersearchpage DONE — removed in PR #176 GET /search server-rendered page. The user-facing search uses the GraphQL search() query (assets/ui/user/search/search.view.ts), not this page. Package deleted and router regenerated.
internal/case/admin/renderlayoutpreview Remove (candidate) Registered endpoint only. No internal callers, not referenced by GraphQL resolvers. No telegram/tg code inside.
internal/case/rendernotepage/view.html Trim Of ~350 lines only LayoutError is still used (endpoint.go:291). The rest (Note, NoteContent, Sidebar, ReadingMeta, ReadingComplexityStars, LatestBanner, TurboNote) has zero callers — superseded by defaulttemplate.
internal/case/renderlayout (Handle + views.html) Remove (unblocked) renderlayout.Handle had exactly one caller: rendersearchpage, removed in PR #176 — so Handle / WriteBeginLayout / views.html(.go) are now dead. Keep the Env/Params types — still used by render404, rendernotepage (buildDefaultTemplateCtx), and admin previews.
internal/case/admin/renderpreview KEEP — do NOT remove Active admin live-preview, NOT telegram. Wired into: GraphQL resolver (schema.resolvers.go:1293 → renderpreview.Resolve), PreviewBuffer (cmd/server/main.go previewBuffer, PreviewBuffer()), and its own config section (appconfig/config.go RenderPreview).

Note: the original assumption that renderpreview / renderlayoutpreview "were
for Telegram" is not supported — neither package references telegram/tg/bot.
renderpreview is the admin editor preview; renderlayoutpreview is an
admin layout preview endpoint with no remaining callers.

Removal steps (when doing the cleanup)

  1. rendersearchpage — DONE (PR #176): package deleted, router regenerated,
    no remaining /search?q= links found in templates or docs.

  2. renderlayout Handle + template (unblocked by step 1)

    • Remove Handle, WriteBeginLayout/WriteFinishLayout/TG-layout funcs, and internal/case/renderlayout/views.html + views.html.go.
    • Keep render.go's Env, Params, HrefLang types (still imported elsewhere).

  3. renderlayoutpreview

    • Delete internal/case/admin/renderlayoutpreview/.
    • Regenerate the router.
    • Before deleting: confirm the admin UI does not call its endpoint path.

  4. rendernotepage/view.html trim

    • Reduce view.html to just the LayoutError func (drop Note, NoteContent, Sidebar, ReadingMeta, ReadingComplexityStars, LatestBanner, TurboNote and their Stream*/Write*).
    • Regenerate: go generate ./internal/case/rendernotepage/....
    • Alternative: move LayoutError into defaulttemplate and delete view.html entirely.

Verification after cleanup

  • go build ./... and go vet ./... clean.
  • go generate ./internal/router/... produces no diff beyond the removed entries.
  • Note page, 404 page, admin editor preview, and admin layout list still render.
  • Search still works from the UI (GraphQL path).
