DL-204

Linear attribution is dual-channel with deliberate granularity: every write passes through StampOwner unchanged (the one chokepoint; the header carries the fine-grained PER-AGENT owner truth) AND sets Linear’s native createAsUser to the ONE general shared Compass app identity (coarse native display, never per-agent; the token is OAuth actor=app, degrading to stamp-only via a named boot-time capability probe on a non-actor token); both values are Server-chosen so DL-050 unforgeability holds on both channels
