feat(phase-14): htmx shareable web client — server-rendered optimizer UI#20
Merged
Conversation
Phase 14 adds a minimal, dependency-free server-rendered web client
that drives the optimizer through plain HTML + htmx attributes. The
point is shareable result links: every run lands at /htmx/run/{rid}
and that URL can be sent to anyone with network access to the API.
Routes (registered in create_app, unauthenticated by design — synthetic
terrain only, no DEM upload, no project leakage):
GET / landing page (length, seed, system, generations)
POST /htmx/run run synthetic optimize, return HTML fragment
with metrics + a permanent run link
GET /htmx/run/{rid} shareable read-only view of a stored run
The implementation is a single ~200 line module (src/ropeway/server/htmx.py)
with no template engine — inline HTML strings with a small CSS block,
htmx attributes for the form post + result swap. Runs are stored in
process memory; the link is valid for the lifetime of the server.
The authenticated FastAPI surface (/auth, /projects, /optimize/dem) is
untouched.
Tests: 5 new in tests/test_server_htmx.py (landing form, run returns
metrics + permalink, unknown system 400, share link returns stored run,
unknown rid 404). Suite 157 → 162.
