| F1 | Two task sessions in one working tree share one git index, and the discipline that protects it lives nowhere durable. The owner instructed both sessions about concurrent execution — «параллельно будет запущен tfw-56 исполнение, так что надо учитывать при коммитах» — and the executor that recorded the instruction as a fact candidate and reasoned about it in writing still swept three of the sibling task's deletions into its own commit. A verbal staging directive has a demonstrated survival rate of 0 out of 1 against a broad git add, which is the structural-enforcement-over-exhortation argument reproduced on the git index. Three consecutive phases of one task then produced three different ad-hoc answers — sweep-and-repair, generate-the-full-diff-and-apply-one-hunk, and leave-it-uncommitted-on-a-verbal-instruction — none written down. Under D55 the commit subject becomes the only record of which task a change belongs to, so a misattributed staging silently misattributes the trace. This is TFW-54's problem arriving before TFW-54: a coordinator running a team of delegate sessions faces the same index with more writers, so its grant must bound what may be staged, not only what may be decided. The concrete missing artifact is small — a staging rule in handoff.md and review.md: stage by explicit path, and what to do when a shared file carries someone else's hunk |
