cg-reftest
Guides design and review of computer-graphics rendering tests for the cg crate. Covers the distinction between reftests (independent oracle), golden/snapshot regression tests (previously accepted output), and observation-based probe tests (pixel/color assertions without vision). Use when adding, reviewing, or debugging visual comparison tests, pixel diffs, golden image generators, SVG reftest suites, or designing fixtures that can be verified programmatically by probing pixel values. Relevant paths: crates/grida-canvas/tests/, crates/grida-canvas/goldens/, crates/grida-canvas/examples/golden_*, crates/grida-dev/src/reftest/, fixtures/test-svg/, docs/wg/feat-svg/testing.md.
