Lower the axial body threshold while retaining fringe rejection, minimize length-only tip inset, and make sheet sensitivity curves testable and conservative at zero.
PhotoStage used new Image() while mask worker and calculate used bare
createImageBitmap; Orientation-8 matched-set JPEGs can disagree across
those paths so the approved pink axis is not the overlay (ux,uy).
One decodeOrientedBitmap helper always requests imageOrientation
from-image (with bare fallback), wired into PhotoStage, mask.worker,
and session calculate/siblings.
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.
Lock length dim to mask tip-to-tip (not oversized bbox), require width
labelAt on axis-left off the wood, smaller font contract, and 90% crop
fill extent. Red before green.
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.
Failing TDD for M2 dimension-overlay copy of the calibration inventory PNG:
width stations every 12 in from EXIF bottom (6, 18, … ≤ L−6), axis-right
length graphic, and Calculate storing overlayPng without touching batchApply[cal].
