Two changes to close the UX hole m hit on slice 6 — Apply Template
appeared to do nothing because (a) the canvas wasn't refreshed cleanly
and (b) the cables hadn't been computed yet.
Backend (internal/server/solver.go applyTemplate handler):
- After ApplyTemplate succeeds, run Solve(false) inside the same
request. Combined response shape:
{ template_apply: <ApplyTemplateResult>, solve: <SolveResult> }
- Opt out with ?solve=0 for power-users who want to inspect the
seeded devices/requirements before the solver runs. Response in that
case is { template_apply: ... } only.
- If Solve fails after a successful apply, return
{ template_apply, solve_error: "..." } so the frontend can recover
(devices are still there; m can hit Solve manually).
Frontend (web/static/main.js apply-template modal submit):
- Replaced the bare re-snapshot with a call to activateProject(pid).
That's the canonical project-load path — it re-hydrates ALL
collections (frames, devices, ports, io_markers, cables, bundles,
requirements, cable_types, device_types), clears state.selection
so a stale pre-apply selection can't linger, and routes through the
same render() the URL-state hydration uses on initial page load.
- The slice-6 inlined re-snapshot missed the device_types refresh +
selection reset, which I suspect was what made the canvas look
stuck — render()ing with state.selection.kind="cable_type" or
"requirement" pointing at a not-yet-loaded row.
Hand-test (local): Living Room + auto-solve produces 4 devices + 3
requirements + 3 cables; ?solve=0 leaves cables empty. Snapshot
includes the cables on auto-solve path.
