The runtime-binding slice — the regime's stop now actually reaches the graph and
the record:
- `StopArm { Open, Bound(StopRule) }` replaces `wrap_r`'s `stop_open: bool` so a
bound stop carries its params; all call sites threaded (the r-sma sweep path
stays Open, every bound site passes the resolved rule).
- `run_blueprint_member` takes a `stop: StopRule` and stamps `stop_length` /
`stop_k` into the member manifest (the ratified C18 extension — the stop is no
longer invisible on the campaign/blueprint path); its callers thread the
default, and `CliMemberRunner` maps `cell.regime` (None -> baked default,
Some(Vol) -> that vol stop).
- The characterization pin flips from asserting the stop's ABSENCE to requiring
the stamped default; a real two-regime e2e pins that each regime stamps its
own k.
Known deferred gap (concern, documented descope): `persist_campaign_traces`
re-runs the nominee to persist its traces and — since `CellRealization` carries
no regime — binds that re-run to the DEFAULT stop, so a non-default-regime
nominee's persisted trace would reflect the wrong stop. Only the persist path
(non-empty `persist_taps`) is affected; the core run/stamp/generalize path is
correct. Filed as a follow-up. Full workspace suite green.
