Theseus field route authoring

Approved: 17 September 2026 (#157)

On the map picker screen, Wantok staff add and connect graph nodes, then save weighted edges through T5 field APIs (POST /theseus/floor/:id/graph).

This amends the desktop graph. It does not replace the web Pixi editor.

No operator-actions row.

Tools

Confirm stays the BLE confirm default. Switch to add-node or connect before drawing:

• Add-node: tap the PNG. Local dx/dy are floor x/y. New nodes use negative temp ids until save.
• Connect: tap node A, then node B. Skip self and an existing undirected pair. Weight is Euclidean distance, one decimal, matching the web editor.
• Bare map taps in connect mode do nothing.

Overlay and save

Snapshot nodes and edges paint on the InteractiveViewer (circles and lines). No Flame. Floor or location change discards unsaved edits.

Save POSTs the full current floor nodes + edges with Bearer th_…. It does not send deleted_*, calibration, or X-Mobile-Api-Key. A 200 replaces local ids from the payload. Snapshot SHA is the bundle hash of nodes/edges; the next snapshot read sees the new routes.

Non-goals

Flame, Pixi rewrite, ruler, delete/drag, multi-floor edges, walk-trace corridors, Gatify, Hansel MAC/holder QR wizard, pathfind, end-user maps, FCM, staff ntfy, safecall-ops, hospital rasters / mar.json.
