Close the fallible handler and example coherence slice: v0 uses typed todo newtypes, Result handler failure mapping, generated form/partial helpers, and page composition; kanban is explicitly marked as an advanced north-star milestone; raw render is isolated behind hemx::advanced::render. req: canonical_authoring/003 req: failure/004 req: public_api/005 req: examples/004
hemx Kanban advanced milestone example
This is an explicitly advanced/low-level north-star boundary sketch, not beginner-facing guidance. It exercises the product boundary described in ../kanban.md; use examples/v0 for the canonical beginner path.
Run:
cargo run -p hemx-kanban-example
Open http://127.0.0.1:3001.
The example is a server-first Kanban board with:
- add-card form
- move-left / move-right card controls
- delete-card controls
- generated target objects for checked slot updates
- tuple-composed
IntoEffectresponses - SSE presence updates
It intentionally uses buttons instead of custom JavaScript drag-and-drop; drag/local-first sync remain north-star features in examples/kanban.md.
