- **Date:** 2026-06-18 - **Driver:** Claude CE, animating this bead from a stac-camera-telemetry (`31f69717`) session.
## Verbatim user prompts (this thread) 1. "find the sandyfire STAC and add this 2026Sandy_v2 toa map. ask bead fire-progress to get the .pgw and .png toa file." 2. "can you mount fire-progression and step?"
## What happened (summary; durable detail in notes/00-step-2026Sandy_v2.md) - Located the SandyFire STAC (`cbf8b027/.../stac/2026SandyFire/`, `progression` collection) and this bead. - First deposited a dock request to this bead for the v2 `.png`/`.pgw`; then, on prompt 2, **mounted this bead and stepped it** instead of waiting: wrote `progression-maker.mjs`, ran it re-anchored to the true ignition origin (17:17 Z), produced `2026Sandy_v2.{png,pgw,json}`, minted the STAC item, replied to the requester dock, and logged this step. - Pending Stephen: `/bead-sync` (`182bd1a7` + `cbf8b027`) so the STAC asset hrefs resolve; optional finer `--cell` re-run; optional incident-viewer wiring.
