What this partner does
The frozen scripted presenter (ADR-026; Gate-0 rig): it hands the part into the shared workspace and lets go, binding the ego only through the presented initial condition. The grasp-pose error distribution (grasp_pose_bias_deg/grasp_pose_sigma_deg) is the coupling channel; lateral offset is success-side by construction and timing skew rides the takt budget.
Construction provenance
Built from registry class handover_presenter (PartnerSpec(seed=0, checkpoint_step=None)). Private member: the exact values are withheld (ADR-009 as amended — published hashes, withheld parameters). They were drawn from the committed box under the maintainer-held seed; the digest below verifies any authorised local re-derivation.

Behavioural fingerprint
Committed probe suite: seeds [7000, 7001, 7002, 7003] x 5 episodes against the task's reference ego (archive: spikes/results/partner-fingerprints/handover_place_partners-v1/presenter_matched/, an ADR-028 v3 bundle). Summary statistics of the member's action distribution and the dyad's stress channel — enough to tell members apart without policy access (ADR-018/I3).
