Lower the axial body threshold while retaining fringe rejection, minimize length-only tip inset, and make sheet sensitivity curves testable and conservative at zero.
Root cause: 0.2%/99.8% axial percentiles still included dense fringe past
the visible body; round line caps and scale-tied font overshot edges and
clipped width labels. Use across-width tip stations, inset length/width
ends for stroke/arrowhead, butt caps, inventory-capped font, axis-right
length label, clamp labels to PNG.
Length dim already mask tip-to-tip (locked by test). Width labels move
axis-left off the wood via labelAt; font steps down to max(22, scale*1.0).
Inventory/overlay crop FILL 0.8→0.9; CAPTURE/PHOTOS docs match.
Add pure station/axis math and canvas burn-in for a second calibration
inventory PNG (results.overlayPng). Width stations start 6 in from the
EXIF-oriented photo bottom along the approved length axis (6, 18, … ≤
L−6); length graphic sits on axis-right outside the slab. Clean
inventoryPng and batchApply[cal]=null stay unchanged.
