- pipeline/dump_bird.mjs: imports web/js/world/magpie.js UNMODIFIED (bare 'three' resolved to the
repo's vendored build through a node resolve hook) and dumps birdGeometry() — so the A/B is
against Lane B's actual bird, not a port. MEASURED 182 tris / 216 verts. --sim walks a player
past a territory on magpie.js's own clock: drawn 54.1% of frames, and OF THOSE perched 80.5% /
swooping 7.7% / returning 11.8%.
- pipeline/bird_to_glb.py: wraps the dump as a GLB in E's frame (head +Z, +Y up) so the identical
render_views.py rig shoots both; --fold applies the perch pose (x x 0.42). glb_stat re-measures 182.
- pipeline/render_views.py --noemit: strips emission from BOTH candidates. normalize.py's
emissiveFactor 0.28 is albedo-MODULATED; a vertex-coloured mesh cannot express that in glTF and
Blender writes a flat 0.28 that lifts a black bird to grey. Off both sides or the picture lies.
- pipeline/view_sheet.py --ab: the strip as a GRID (one line per candidate, stacked) plus two
linear motion-blur blocks at 25% and 100% of the bird's width, and a wrapped notes footer.
- docs/shots/laneE/r39_magpie_ab.png — the sheet Fable rules on.
Recommendation in LANE_E_NOTES; picture first.
