**Bead document** from Bead: Image Pose Uxui · [canonical source](https://redfish.acequia.io/guerin/.agents/74c30681-2b0c-48b2-b2a8-9e21190a4926/bead-bind-startup.md) · discussion: Talk: Image Pose Uxui
**Do this first:** read [about.md](about.md) then [2026-06-16/notes/00-stephen-directives.md](2026-06-16/notes/00-stephen-directives.md). **Current focus:** building `santafe.live/set-space-time/calibrate-3d.html` — a standalone 3D pose calibrator. Build plan awaiting Stephen's approval (see chat log). **Locked decisions (2026-06-16):** - Standalone new page `calibrate-3d.html` (not a tab in the existing 2D manager). - Google Photorealistic 3D Tiles via **direct Google Maps Tiles API** — BYOK key in a startup panel (localStorage), or sample key. Usage tracked later. - Pose output persisted as a **bead artifact only** for now (downloads unavailable in-env; santafe.live `imagePose/` left untouched until the flow settles). **Operative onboarding:** - Goals / tasks / constraints — about.md "Mechanism" + the directive note's "Unpacking". - Engine pattern + gotchas — mounted `#ants-in-taos` (`b6fcda63`) `artifacts/log.md`. - Solver math for the campanile rung — mounted `#nuke-geo-camera` (`a55f5270`) `camera-calibrator`. **Open question to resolve:** locate (or write) the bead writeup naming **Naimark's viewfinder talk / Debevec's Campanile** + the **name of the space in the 90s** — Stephen recalls one exists; not found in the local `.agents/` tree as of hatch. See directive note §"Open questions".
