The origin check is an exact match including the context path, so users had
to type "https://collab.lge.com/main" precisely. GET /api/v1/config now
returns the approved origins in canonical form (non-secret: they are the only
destinations the backend will talk to), and the UI swaps the URL text field
for a select listing them, keeping the element id, focus handling and the
Test connection flow unchanged. The text field remains the fallback when the
fetch fails. Backend validation of the submitted URL is untouched. Mock server
serves the endpoint; contract, API and e2e tests cover it.
Submit joins the admission queue first and sends the PAT only once the
reservation is held. Queued state shows the shaping orb, ordinal position
with estimate, and an exit button whose label changes with the wait;
running switches the orb to solving. Rejoin once on a lost reservation or
ticket, best-effort leave on pagehide. Mock server gains the queue
endpoints and five scenarios; contract, unit and e2e tests cover them.
Replace the gear spinner with the thinking-orbs canvas engine (vendored
framework-free build, driven by js/orb.js in the "solving" state) and the
inline SVG brand icon with a pure CSS book whose cover flips open on page
load and while the brand is hovered (js/logo.js).
Static frontend with vendored marked/DOMPurify, bounded Markdown
pipeline, same-origin mock server with scenario selection, unit,
contract and CDP end-to-end tests under frontend/**.
