Private runtime trace objects [read, original owner only]

Paginated original capture objects, including raw frames, native transcripts and model-call bodies. Retained operating evidence remains readable after soft deletion; this does not restore the Session. Requires session management authority and the caller to own both the Session and its Agent definition; a hire, shared transcript or pod credential is insufficient. Object URLs expire after 15 minutes and bind the listed generation. Never log or persist URLs. Capture may be partial or missing; this is operating evidence, not a training/export consent grant.
