**Current-state tap-plan sentence (2026-07-21, #283; superseded 2026-07-24 by
the #310 `--tap` selector):** "…and the shared `bind_tap_plan`/`BoundTaps`
pair called by both declared-tap entry points, `run_signal_r`
(`aura-runner::member`) and `run_measurement` (`aura-runner::measure`); both
CLI verbs pass a record-all plan."
