 - The S06 acceptance seed must backdate both `JobApplication.FollowUpAt` and the latest correspondence timestamp past the user’s `AppliedFollowUpDays` threshold; `RulesEngine` computes `Waiting` follow-up from the most recent activity (`DateApplied`, `ResponseDate`, `FollowUpAt`, `FeedbackRequestedAt`, or last correspondence), so a recent reminder date can suppress the intended `workflowSignal.actionKey = "follow-up"` fixture.
 - In this M001 worktree, the local SQLite DB contains `admin@example.com` with the `Admin` role even when the placeholder `Auth:AdminPassword` from `appsettings.Development.json` no longer authenticates. For repeatable localhost acceptance reruns, `scripts/s06-acceptance-run.sh` can mint a dev-only local JWT from the checked-in JWT settings instead of depending on a manual bearer-token export.
 - `scripts/s06-preflight.sh` intentionally exits 0 on the auth-limited path where `/api/auth/config` is reachable but `/api/admin/system` returns 401/403. Treat that as a guided partial pass for browser/UAT prep; only unreachable API, malformed JSON, or non-auth admin failures should block the slice.
+- In this M001 worktree, the focused CRA regression command `CI=true npm --prefix /home/pi/development/JobTracker/.gsd/worktrees/M001/job-tracker-ui test -- --runInBand --watch=false src/daily-control-loop.test.tsx src/workflow-trust-signals.test.tsx` can fail with `react-scripts: not found` even when `job-tracker-ui/node_modules` already exists from an older install state; rerun `npm --prefix /home/pi/development/JobTracker/.gsd/worktrees/M001/job-tracker-ui install` first, then retry the exact test command.
