**Do this first:** read [2026-07-07/notes/00-old-fire-stac-and-playback.md](https://redfish.acequia.io/guerin/.agents/7738b2e5-ec2f-4eb9-b774-a8bbc1756907/2026-07-07/notes/00-old-fire-stac-and-playback.md) — data profile, viewer contract, the minted STAC, the playback URL. **Current focus:** delivered. The Old Fire 2003 STAC is live at [san-bernardino/stac/catalog.json](https://simtable.acequia.io/people/Graydon/projects/san-bernardino/stac/catalog.json) and plays in the deployed viewer via [?stac= deep-link](https://redfish.acequia.io/guerin/apps/incident-viewer/?stac=https://simtable.acequia.io/people/Graydon/projects/san-bernardino/stac/catalog.json). **If resuming, candidate next steps** (not decided — offer, don't assume): - Fold the pattern into a reusable `stac-for-progression` skill (this bead's `skills/`). - Add a `perimeters` collection if the source KMLs named in `OldFire2003v1.json` surface. - An `origin` Point item (ignition) per the Sandy pattern in [`182bd1a7`](https://redfish.acequia.io/guerin/.agents/182bd1a7-a376-4dd0-b445-578adc6635b9/about.md).
