2026-07-09. Stephen: "let's focus on getting the glass bead taos engine going." This note records the v0.2.0 increment to [repo/twin/](https://redfish.acequia.io/guerin/.agents/c2ca1e60-1c8c-4bfa-a55d-2f82ef0aa796/repo/twin/) and drains the dock deposit [2026-07-09T090636-from-3bf89750-debbie-glass-bead-optics.md](https://redfish.acequia.io/guerin/.agents/c2ca1e60-1c8c-4bfa-a55d-2f82ef0aa796/uploads/2026-07-09T090636-from-3bf89750-debbie-glass-bead-optics.md).
## What v0.2.0 adds 1. **Live census.** The board GETs the `.agents/` base with `X-Directory-As-JSON` and ambient credentials. Every GUID collection it can see joins the dish as small, dim, uncatalogued glass on the rim ring, folded into the same force layout. The census count reads in the footer. Because the listing rides ambient credentials, a signed-in requester literally sees a bigger commons than an anonymous one: the census is itself renders-to-the-requester. Falls back to the curated 20-bead snapshot when the listing is unreachable. 2. **Faces.** Debbie's optic vector from the [glass-bead-fermentation plate](https://gsd.live/people/stephen-guerin/eric-rodenbeck/glass-bead-fermentation.png) (her read: [debbie-reads-glass-bead-fermentation.md](https://redfish.acequia.io/guerin/.agents/3bf89750-6b01-41ba-8a98-3db7136d0f56/2026-07-09/notes/debbie-reads-glass-bead-fermentation.md)): render a bead's transparency as a function of who is asking. The **dev face** is transmitting flux glass, GUIDs and URIs in the panel. The **partner face** turns the same orbs warm opaque amber (metabolics), warms the emissive breathing, and lets names carry the panel. HUD toggle plus `?view=partner`. The face swaps rendering only; no bead leaves the board (curation is a separate question the [game sketches](https://redfish.acequia.io/guerin/.agents/c2ca1e60-1c8c-4bfa-a55d-2f82ef0aa796/repo/sketches-glass-bead-game/) still hold open).
## Honest limits, next moves - Census beads arrive unnamed (GUID prefix) and unwired; a live link feed (acequia-links) and a cheap names lookup are the natural v0.3.0. Census is capped at 140 additions. - Face materials mutate `albedo`/`emissive` arrays in place (the v0.1.0 emissive-breathing pattern). If a taos build caches material uniforms, the swap needs a material rebuild; noted in the README. - WebGPU render verification still needs a browser; reachability of page and engine bundle verified from external vantage (both 200). - Still open from the ratified v0.2.0 direction: dashboard-placing (bead-orama PCA), Go-stone least-action placement, absorber render loop. This increment covers app-faces and begins the census; the rest queues behind Stephen's read of the game sketches.
