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.
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.
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].
Product call for the WooCommerce redo. Calculate accepts
sources whose post-crop shorter side is at least 800px.
Warn copy and CAPTURE.md match. No upscale still holds.
Ty UAT rejected phone photos under the 1600px bar.
Lock the mid-band case (shorter side 1000) and floor
geometry at 800×1067 / 0.8×800=640 before the code change.
Why
CAPTURE.md Crop keeps slab pixels and makes removed pixels transparent.
encodeInventoryPng only drawImage-cropped the AABB from the raw photo.
Scope
composeInventoryFrame samples the source through approvedMask.bitset.
Non-slab pixels stay alpha 0. Drop the 8% MARGIN; fill 80% of mask
extents in a 3:4 frame. Floor rules unchanged.
Verification
cd frontend && npm test
12 pass, including alpha contract (no sheet green in opaque pixels).
Why
Calculate showed accurate numbers but the inventory PNG kept the sheet
background. Measure already uses approvedMask.bitset; encode did not.
Scope
Add composeInventoryFrame and inventory.test.ts alpha/crop proofs.
Wire encodeInventoryPng({ bitmap, mask, source }) at calculate().
This commit still paints the slabBounds AABB without the bitset gate so
the alpha contract fails until the follow-up fix.
Verification
node --import tsx --test src/png/inventory.test.ts
alpha contract fails (sheet green leaks); 3:4 / 80% / floor pass.
Why
Phone and PC need a single capture flow that ends at inventory PNG and
board-foot numbers with no backend, inference, or Woo create.
Scope
Add frontend/ Vite+Svelte capture UI with Resume, Add photo, Mask,
Length axis, and Measure. Mask runs in a worker with Auto/Green/Black
and a 2.0s sensitivity debounce. Measure computes scale, widths, sqft,
bdft, and a 3:4 alpha inventory PNG. Persist one device draft in
IndexedDB. Serve the static build from frontend/Dockerfile via nginx
(deploy/nginx-m1.conf). No FastAPI.
Verification
sudo docker build -f frontend/Dockerfile -t slabuploader-m1 .
sudo docker run -d --name slabuploader-m1 -p 0.0.0.0:18080:80 slabuploader-m1
curl http://127.0.0.1:18080/ returns 200
Playwright: synthetic green-sheet photo through Calculate shows sqft/bdft
