The decisive structural fact: + **INV-9 + INV-10 mean the machine writes the document only through + `applyAgentEdit`, only at accept time — so between machine landings, + every buffer change is operator-authored.** +4. **The baseline fork (load-bearing)** — resolved to a + **machine-landing–anchored auto-baseline + human pin**: initialize at + first track, advance on every successful seam application; the diff is + operator-authored *by construction* (new **INV-18**).
