Checksums
t27f.build, next to this file, is the record: `#` lines hold the inputs of the build (closure digest,
zig version, t27c sha256) and every other line is `<sha256> <file>` for the vendored wasm, the vendored
view constants and the vendored specs. It is a copy of the lines of gHashTag/t27-mcp wasm/t27f.build
that name files kept here, produced by the rule in gHashTag/t27 specs/t27f/build.t27 (#10229), not typed by hand. Check it with
`npm run check:t27f` in apps/website; one changed byte names the file. (The generated Zig the wasm is
built from is not vendored; its checksums are in the t27-mcp record.)

Reproduced on the Railway lab on 2026-10-18 from these vendored specs:
t27c gen-js spec_graph_view.t27 gives spec_graph_view.mjs byte for byte;
