compare-dirs gains --artifacts changed|always: 'always' also writes the
side-by-side triptych + heatmap for pairs that PASS the floor (blue-grey
UNCHANGED caption), so a human can eyeball old-vs-new without a failing
gate. The gating scripts keep the default (empty diff dir = green);
3d:review writes the full 47-pair set to output/diff/parity-review/.

- baseline-webgl/: first population from the passing local Chromium renders
(47/47 under the parity floor) — activates the webgl-self regression gate
(floor 0.005). CI may re-promote its own renders if the Linux/swiftshader
rasterization differs beyond the floor (the README's CI-promote flow).
- compare-dirs.ts: recreate the output dir on every run — triptychs/heatmaps
are only written for CHANGED pairs, so artifacts from earlier (redder) runs
lingered and misreported scenarios that had since gone green (a stale
red-state gen-cylinder triptych survived three green runs).

tests/3d-regression mirrors the gal-regression pattern at renderer scale:
shared C++ scenarios call real KiCad 3D-viewer code (opengl_utils, display
lists + DrawCulled stencil subtraction, MODEL_3D VBOs, private generators via
a rob-template accessor, and full reload()+Redraw() composites over a
synthetic BOARD_ADAPTER). A native macOS harness renders them on real OpenGL
into 47 committed goldens (bit-deterministic, FBO capture); the wasm harness
compiles the same TUs against wasm/stubs/gl_ffp_stub.c no-ops so every
scenario renders blank — the TDD red state (parity meter: 47/47 changed).
Comparisons use the CI pixelmatch engine via the new generic compare-dirs.ts
(floors.json levels; manifest.json cmp-guards registry drift).
Documents an upstream bug: appendPostMachiningGeometry's countersink path
adds middle quads without normals, silently erasing the walls of any
display list it is batched into (3d-post-machining.png keeps the lists
separate to record it).
