Decide #310's data-authorability fork as (b), split by run-mode authority: selecting a Named fold subscription is data-reachable on the one-shot run path; adding a fold stays a Rust entry (role 2, C25). `aura run` gains a repeatable --tap TAP=FOLD selector feeding the existing TapPlan seam: no flag keeps the record-all default; any flag replaces the plan entirely (unlisted taps stay unbound — C27 inert, non-error). Validation stays in bind_tap_plan (roster-enumerating label refusal, typed UndeclaredTap, both before store I/O); parse-level refusals (malformed pair, duplicate tap) exit 2 via the verb's usage convention. Rejected alternatives (minuted on #310 with the skeptic-pass rationale): an op-script/blueprint carrier (C27 forbids recording policy in the serialized fragment); ratifying Rust-only (softens a designed-in promise with effort as the only rationale). The campaign/document carrier and the persist_taps/declared-tap namespace reconciliation are deferred to the Measurement-reachable milestone (#312/#327, minuted on #312). Ledger: C27 Current state records the boundary; the superseded sentence moved verbatim to the new c27-declared-taps.history.md sidecar; the glossary tap-plan paragraph updated, fixing the pre-existing inaccuracy that named `aura measure` a record-all-passing verb (it is the post-hoc IC analysis and constructs no tap plan). Verification: 5 new unit tests (parse branches), 5 new binary-level selector tests incl. a byte-identity pin of an explicit all-record plan vs the record-all default (C1), 1 measurement-arm test; full workspace suite green; clippy -D warnings clean. Independent opus diff review: approved, no Important/Minor findings (nits: inert-arm generic refusal, a=b=c falling to the roster refusal — accepted as-is). closes #310

**Current-state tap-plan sentence (2026-07-21, #283; superseded 2026-07-24 by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."
