Existing <verification> required tests pass + lsp clean + build green, but
that is insufficient for end-to-end delegation. Tests cover known cases;
they do not cover whether the user-visible feature actually works.
Add a NON-NEGOTIABLE rule: when the user hands off end-to-end ("ulw",
"implement and finish", "do the whole thing", "make it work", "ship it"),
verification escalates to:
1. BUILD the actual artifact
2. USE IT YOURSELF as a real user would
3. VERIFY end-to-end behavior matches the spec
4. TASK NOT DONE until usage confirms it works
Reporting "implementation complete" without having USED the artifact is
explicitly framed as a contract violation. Defects discovered during this
QA pass are the agent's to fix in the same turn.
This complements the existing 'lsp_diagnostics catches type errors, not
logic bugs' line by giving full-delegation cases a sharper, named gate.
