"The original, except these. A replica earns its 'better' one ruling at a time."
The Oracle Rule Has a Second Clause
The replica program's law was: the original is the answer key. But a perfect replica of a living tool is a dead end, because the original itself was never finished — it was growing. So the law got a second clause: the original, except these. A departure is a place where v4 behaves differently from the app it replaced on purpose — and the bar for 'on purpose' is strict: Dad's decision, recorded with its date and his reasoning. A developer's quiet simplification doesn't count; that's the drift the whole program exists to prevent.
The Seven, All Ruled in One Week
The seven in this lesson all landed in the days right after the cutover, each one a sentence from Dad followed by a recorded change. New documents are notes now: the tab strip's + and ⌘T create a library note with its metadata form and autosave, because '노트 만드는 게 정석이야' — making a note is the standard — and a raw untitled buffer has no form and doesn't save on focus loss. The note list re-reads itself when another replica's sync lands, because his iPhone writes into office now. Todo became a selection command — select lines, get a checklist ('여러 줄 늘어놓고 선택한 다음 todo 로 지정하면 체크리스트 만들어줘야 제대로 된 UI/UX 지') — and a Todo box is clicked, not typed ('클릭해서 채우지'). Rendered arrived as a read-only document view beside Editor and Corkboard, because '공간 낭비다' — the centered 68ch export column was wasting the pane. A dropped .md opens instead of attaching. And Refresh closes the status-bar Pippa chip, because '눌러서 리프레시 하고 나면 안 닫혀' — it didn't close.
Why the Ledger of Exceptions Is the Product
Here's the subtle part: the departures don't weaken the oracle rule — they're what keep it honest. Without a recorded-exceptions list, every improvement silently rewrites what 'the same product' means, and a year later nobody can say whether a difference was decided or just happened. With it, the contract stays crisp: match the original everywhere except this dated, ruled, quoted list. The fixtures stay the original's; the tests apply the departures on top. It's the same governance shape as a constitution with amendments — the document doesn't pretend the founders foresaw everything; it just refuses to let change arrive unnamed.
