Left-ear moat editing reference

The current master uses a single C-shaped moat and bridge B only. The lower-moat refinement trims the outer lip below the island, smooths its baseline kink and lowers the front sensor/regulator block. The exterior, LEDs, connector and B remain held. The earlier AW routing refinement smooths the outer pocket edge above the regulator and removes the small step along the baseline-side cut. The 2026-10-25 pocket adoption removes A and rounds the new island corner; the former two-cut/two-bridge arrangement is historical. Use the design reference for current population/geometry constraints and the connector guide for J1. The 2026-10-17 adoption record preserves the old measurements, component counts and verification results.

Saved-board export

just ear-moat-svg build/moat-next
# Or: uv run --script scripts/hw.py ear moat-svg --output build/moat-next

Choose a fresh destination. The CLI first reproduces the held fit guides, then exports the saved left board through the private KiCad worker. It requires the current three independent B.Cu electrodes (or legacy two /TOUCH regions) and checks the guide record against the saved LED poses. It does not include unsaved editor changes or change the source. See the tooling guide.

The retired standalone exporter required /TOUCH_A//TOUCH_B and F.Cu fill; that incompatibility was corrected during consolidation. Old exports remain historical snapshots. For native board/preview generation, use the pair/panel guide.

Fit guides and manual artwork

just ear-fit-69-current reproduces the held poses and editable guides from docs/ear-fit/alternatives/69-led/source-refinements.json under build/ears/left/fit-69-current/. just ear-fit-69 reproduces the original frozen record; it is not a fresh source-board export. See the fit record.

The historical native SVG exports use millimetres: open in Illustrator at 100%, check the 10mm calibration bar and preserve registration. Raw reference-pattern coordinates use points; do not import those directly as PCB cuts. Guides and reference labels are editing overlays, not PCB silk or approved cut geometry.

Keep manual artwork outside disposable build/, which just clean removes. New cut geometry needs its own authorised design task and copper/coverlay, bridge, support and physical-fit review. Rear adhesive naming and construction requirements are in the design reference.
