validate == runnable (fieldtest 0107 F7): validate_campaign_refs now
checks the reverse direction — every open param of the resolved
strategy must be bound by some campaign axis — emitting the new
RefFault::ParamNotCovered { strategy, param } with the RAW
param_space() path; ref_fault_prose phrases it ('open param "X" is
bound by no campaign axis'). The executor's every-open-knob-required
rule is thereby mirrored at validate time, and campaign run's
referential gate catches an uncovered knob before any member binds.
The e2e fixture that legitimately under-covered (fast only) gains the
slow.length axis.
Second half, RED-first: the member-bind refusal no longer leaks the
wrapped bind-time path — it names the raw campaign-axis namespace with
the wrapped path as a parenthetical ('open param "threshold" ...
(wrapped path: sma.threshold)').
RED evidence: E0599 on the pinned ParamNotCovered test (tdd-author
handoff), then the flipped bind_axes prose pin observed failing on the
wrapped form.
Gates: workspace 988/0, clippy -D warnings clean.
