Four acceptance commands in this backlog could not pass as written. The
fourth, in RD-09, reached this backlog's own ticket files and 22
gitignored worktrees, so satisfying it literally would have rewritten the
history of completed tickets.
The general fix is `git grep` instead of `grep -r`: it searches tracked
files only, so untracked and gitignored paths cannot pollute the result.
Measured here, `grep -r` finds 132 hits under .claude/ where `git grep`
finds none. RD-17, RD-18 and RD-19 are repo-wide sweeps and depend on
this.
Also correct RD-09's Order row. It claimed the ticket covered a generator
and a skill file; neither teaches the deleted idiom, as recorded in
PLAN.md.
