id: design: shader asset format — named-format shader units with declared inputs, gated by the ranking system

Part of the worlds design program: #5955. Wave-2 follow-up from the prior-art research (Lane B item 41); parent topic issue: #5970. Research source: workspace/scratch/worlds-capabilities-brief-2026-11-04/prior-art-research.md.

Scope

GLSL fragment shaders in the Shadertoy format (mainImage(fragColor, fragCoord) + iChannel inputs) are the de facto portable shader unit; WGSL is the emerging WebGPU counterpart. No cross-engine standard exists — so worlds should treat shaders as data in a named format with declared inputs, gated by the cost-ranking system (sibling follow-up under #5955), not as code in the world language. This also answers #5970's open question — do user shaders go through the user-function compile/trust pipeline? — with: no; they are data assets with a declared input surface, and their effect is bounded by the presentation layer.

Format v1: Shadertoy-compatible GLSL unit + declared inputs (which asset parts it may read/transform).
WGSL track: when it lands, a second format name, not a conversion promise.
Licensing hooks: a shader upload carries the standard license tag (licensing children of id: design program: worlds — advanced Roc libraries, capabilities, permissions, dynamic user functions, licensing (2026-11-04 brief) #5955). Note the cautionary precedent from the licensing research: Shadertoy's own default for user shaders is CC BY-NC-SA 3.0 — defaults become the de facto license of the whole corpus.

Done looks like

A format spec (unit shape, input declarations, format registry) the presentation layer can implement.

🤖 Agent note · handed off

Agent: fleet monitor (repo-fleet-monitor)
Session / ID: task 10379 · repo-fleet-monitor run 2026-11-05 20:12 CST
Found via: monitor reconciliation
Task: Claim evaporated — the previous holder's claim on task 10379 ended without a terminal verb and the task is queued unclaimed (attempts 6/12, last checkpoint stage: handed_off). Labels reset to the truth: queue/queued + status/needs-triage. The fleet monitor's dead-in-queue pass this run also raised the attempt cap where it had been reached.
Expectation: the next queue claimant picks up task 10379 from the handed_off checkpoint; no work was lost.
