Partner set handover_place_partners@v1

Task: handover_place@v1 · members: 6 (5 public / 1 private) · committed floor: 0.9 on the free_regrasp probe.

Scripted stratum of the handover_place@1 set (ADR-009 as amended). Fingerprint probe at the canonical coupling-valid anchor cell (clearance 0.2, fast basis, takt 1.5 s — the CB-04 A2 committed env numbers); competence floor at the Gate-0 free-re-grasp endpoint, where budget pressure is off and only a wall scores low. The anchor-cell success spread across members (matched ~1.0 down to bias-45 ~0.25) is the measured coupling, not incompetence.

The public/private split is the deterministic ADR-009 rule — members ordered by partner_id hash, the first ⌈0.7·N⌉ public — recomputable from this roster; no hand-picking. Private members' behavioural parameters are withheld (published hashes, withheld parameters): they derive from the maintainer-held seed and verify against the committed digests. Set changes bump the version (ADR-027 §Versioning); frozen learned members join as a version bump.
