What this changes

Before. On main after #81, the designs of issues #77 and #80 are closed or refused, but the plate audit had no row for any of them, so a later change could bring their open edges back unseen.

After. The plate audit builds 14 more plates: the 2.2 mm magnet over a 2.4 mm and a 2.3 mm shank at 35.93 mm (refused by the magnet's pocket, built at the widest shank taken), the 6.04 and 6.048 mm heads under the 6 x 2 magnet, the 10.54 mm head over the 10.28 mm magnet on a 2 x 2 plate, the 41.24 mm jigsaw with the magnet 2 and 2.2 mm deep and the 7.498, 7.502 and 7.31 mm heads, and the 34.04 mm corner-pocket plate with a 2 mm hole at its 5.8 mm cap and at the two sizes past it (the second is the issue's link, now refused). Nothing else changes: no engine code, no page.

How. Rows in test/plate-audit.js only, each with a comment saying what it pins and what main did (the 2.4 and 2.3 rows, the 10.54 rows, the jigsaw rows and the 5.81 and 6 mm rows fail on main 326cc48; 6.04 and 6.048 pass there too and pin the band MOUNT_BORE.head.snap). A re-sweep of both issues on c0dc948 (21,916 corner-pocket designs the page takes, and about 43,000 near-equal magnet, counterbore and shank sizes) found that #81 closed both issues' own cases but that two smaller leaks remain, which the page takes with no warning. They are filed on their own with repro links and are not fixed or pinned here, so this says "Refs" and not "Closes":

• Baseplates: corner pockets with screws leave 3 open edges a cell at 34.32, 34.73 and 38.95 mm #91: corner pockets with screws leave 3 open edges a cell at 34.32, 34.73 and 38.95 mm (what is left of Baseplates: corner pockets with a 2 mm screw hole leave open edges under the bosses at 34.04 mm #80);
• Baseplates: a screw bore of nearly the magnet pocket's width leaves 6 to 12 open edges a cell at 42 mm #92: a bore of nearly the pocket's width leaves 6 to 12 open edges a cell at 42 mm (what is left of Baseplates: a magnet pocket and a screw bore of nearly the same width can leave bad edges #77).

The report is /mnt/project-files/issue-batches/issue-77-80-report.md. The review's "about six designs worse than main" for #81 do not reproduce.

Checks

• I edited the sources in src/, not the generated index.html / bins/index.html: src/ is untouched, only test/plate-audit.js
• I ran node build.js and committed the regenerated pages alongside the sources: it rewrites nothing
• npm run test:all passes (run here on 709a07b over c0dc948: npm test exit 0 and the plate UI specs plates-input, plates-robustness, export, keys and half-cells, 186 passed; on 6537ff9, the merge with main 1e1c48a, node test/plate-audit.js clean, build --check and ci-sim clean; the whole UI suite is left to CI)

If this touches geometry

It does not touch geometry.

• Baseplates: node test/plate-audit.js reports all plates watertight, and no case has picked up bad edges that were not already named as known
• I added cases for the shapes the issues named
