Earned by a real mistake this session: `web.Handler` gained a parameter, its
caller in cmd/ was updated in the working tree, and `git add internal docs` left
that caller out. verify.sh was green throughout, because every gate looks at the
files on disk rather than at the commit being made. The result was a commit that
did not compile — the kind of thing git bisect trips over for as long as the repo
exists. I rewrote the two local commits rather than adding a fix-up on top.
The check builds a throwaway checkout of the index via `git write-tree`, so it
cannot touch the real index or working tree, and it only runs when something is
staged. Proved both directions: staging a signature change without its caller
fails, a clean tree passes.
Eighth gate defect found by running the harness against real work rather than
reasoning about it — and the first that was a missing gate rather than a wrong one.
