Why

This PR authors the terrarium enclosure in JSCAD and the indexed coupon in tscircuit. Both trees are on the branch. The review catalog is a separate entity. Its components bind generated/ and the tsci dist/ / __snapshots__/ outputs. This PR is not empty.

Official @jscad/svg-serializer fills geom2 black. The first generate pass only projected the envelope, so front.svg, side.svg, and top.svg were filled 250 x 500 slabs. Generate now converts project() outlines to colored path2 and writes a stroked still for every authored solid.

Scope

Write-set is both trees:

• projects/biomemetics/labs/mantis/terrarium/cad/jscad/**
• projects/biomemetics/labs/mantis/terrarium/ee/tscircuit/**

CAD keeps one 250 x 250 x 500 mm envelope, origin front-left-bottom, X-right Y-back Z-up. Named solids from PARAMS are B01 24 mm REF cubes and B05/B06 202 x 3 x 427 mm plates. Placement of the plates is UNVERIFIED. Cassette seat is stock + 0.20 mm TARGET, recorded, not a pocket. No packets/ folder. No PACKET.md.

npm run generate writes stroked front, side, and top SVG for envelope, B01-corner-block, B05-view-cassette, and B06-front-door. Envelope keeps front.svg, side.svg, and top.svg. Every solid also writes {solid}-{view}.svg. generated/VIEWS.md lists each file. B01 is one unique 24 mm cube. The eight instance origins are recorded in VIEWS.md. Pocket cuts and gasket Z are omitted.

EE authors index.circuit.tsx. Native tsci outputs live under dist/ and __snapshots__/. packet/ is gone. No packet.json. No pointer field. B19, B27, B44, B48, S1, S2, Q1, and P01–P12 are BOM balloons compiled on this coupon. They stay UNVERIFIED. There is no admit-list. B19 pads stay omitted. S1, S2, Q1, and B44 pin2 stay NOT_CONNECTED. MPNs stay blank.

Does not write skill files. Does not touch leftover FreeCAD/OCCT, KiCad, S00–S11, packages/lab-ui, specimendb, assistant/, or procurement. PR 34 and PR 36 stay emit. Leftover S00–S11 stay extract. Merge stays held. No Gerber. No orders. No tsci push.

Recipe is extrusions.project, geom2.toOutlines, closed path2.fromPoints, colors.colorize([0, 0, 0, 1], path), then svgSerializer.serialize({unit: 'mm'}, ...paths). Generate never passes geom2 to serialize. Class generated, not shop-release. In-house print is FDM on Bambu. Printer model is UNVERIFIED.

Tradeoffs

Official serializer sets root stroke-width="0.1px". Large plates read as hairlines in a small preview. B01 (24 mm) is easier to see. We did not invent a second SVG writer or copy leftover OCCT stroke-width.

Blast radius

Reviewers of the terrarium CAD and EE trees. No existing caller imports these packages. Merge stays held.

Verification

CAD, this revision: npm run generate, npm test, and npm run typecheck exited 0 in terrarium/cad/jscad. Thirteen tests passed. generated/B05-view-cassette-front.svg is width="201.9999mm" height="426.9998mm" with stroke="rgba(0,0,0,1)" and no fill="black". generated/front.svg stays the 250 x 500 envelope outline.

EE, prior revision: tsci build, tsci snapshot --update --3d, tsci export, and tsci check exited 0. npm run typecheck and npm test exited 0. Eight tests passed.
