# superstack-scope Bound the task before building. Produce a short **scope block** and stop for the human only if a fork genuinely changes what you'd build. **T1 fast path:** reversible and local → write the one-line check (step 1) and go. The full block below is for T2+ or fuzzy scope. **First, read `.superstack/project.md` if it exists** — it holds this project's acceptance oracle, conventions, and known **gotchas**; scope on top of it (don't re-derive what's there, and don't re-step on a logged landmine). If it's missing, offer to create it (see the method skill's overlay protocol). Then: 1. **Define done as a named external CHECK.** In one sentence: what artifact exists at the end, and *what will "correct" be compared against*? Prefer a concrete oracle (a known-good output, a reference system, a test, a count). If no oracle can exist, name the weakest acceptable substitute (a specific human's sign-off) — and say so. **If you can't write the check, you don't understand the task yet.** In an unfamiliar or long-untouched codebase, **run that check before changing anything** — you can't attribute a failure to your change if you never saw pre-change green. 2. **Split known from assumed.** Two short columns: *Known (evidence)* vs *Assumed (inference)*. Anything in the second column that would change the solution if wrong is a candidate unknown. 3. **Name the 1–3 load-bearing unknowns** — the facts that, if wrong, change the whole shape — and the *cheapest probe* to retire e
