Development record

2026-10-31 — spc-2609202134338445 step 11, fix round 1: the auto-plan start records a digest of the checkout (HEAD plus the tree its working tree stages to in a scratch index, the local tier removed), and a checkout that changed is handed back after the reviews and before the plan. Grounds: git status --porcelain names paths only, so a second edit to an already modified file would go unseen; a scratch index stages content as the person's git does without writing the checkout's own index. The row re-check runs before the checkout check, so a change a row names is reported by its row.
