Summary

src/resolution/go-stdlib-methods.ts (#2759) lists the methods of 130 standard-library types, each as name:params/results. It was generated from Go's own source, but the generator lived in a validation kit, so updating the table for a later Go release would have meant re-deriving the counting rules. This checks the generator in as scripts/gen-go-stdlib-methods.mjs:

npm run build
node scripts/gen-go-stdlib-methods.mjs <GOROOT> [--write]

• What it reads: <GOROOT>/src/<import path>/*.go (tests skipped) for every type the table lists now, with the engine's Go grammar. To add or drop a type, edit the table and rerun.
• Which methods it lists:
  • an interface's own methods and those of the interfaces it embeds;
  • a struct's or other named type's methods (receiver T or *T) and those its embedded fields promote;
  • an alias's target's.
• How it counts: with the engine's own goSignatureArity, imported from dist, so a table method is held to what the arity gate reads off a project method's stored signature.
• Which names it keeps: exported names, and an unexported one only where a listed interface requires it (testing.TB's private).
• Output: it prints the table body; --write rewrites it in place, keeping the file's line endings.
• Exit codes: 1 when a listed type isn't found or a signature doesn't read, 2 when the Go tree or dist/ is missing.

The module's doc comment now points at the script.

Validation

• Against go1.27.3 (a sparse checkout of the packages the table reads), the printed body equals the merged table byte for byte. --write leaves the module byte-identical (same md5), both before and after this PR's doc-comment edit.
• A Go tree without those packages exits 1 and names all 130 types as not found.
• No runtime code changes, only a doc comment, so there is no graph to compare. No CHANGELOG entry, since nothing user-facing changes.
• Full suite on this head (c985f59, on main 847f1df) with --maxWorkers=4 --minWorkers=1 and the kernel built (CODEGRAPH_KERNEL_EXPECT=1): 698 files, 8342 tests, 8260 passed, 0 failed, 82 skipped.
