Struct TranscriptSubscription 

pub struct TranscriptSubscription {
    pub namespace: String,
    pub workflow_id: Option<ProtoWorkflowId>,
    pub activity_id: Option<ProtoActivityId>,
    pub attempt: u32,
    pub after_seq: Option<u64>,
}

Subscribe to the agent-observability transcript for one (workflow, activity, attempt) (NOI-5b).

Namespace-scoped: the transcript belongs to the workflow the activity runs under, so this carries the same namespace + workflow_id the per-workflow event subscription does, plus the activity_id/attempt axes that pin the exact O-keyspace stream. The optional after_seq resume cursor is the highest store_seq the client has already applied; the server replays the durable O tail with store_seq > after_seq then splices onto the live broadcast with no gap and no duplicate (the same splice contract the workflow path’s resume_from_seq uses, but keyed on the commit-allocated store_seq).

Fields

namespace: String

Caller namespace used for adapter-boundary authorisation (the workflow’s namespace, identical to the per-workflow event subscription).

workflow_id: Option<ProtoWorkflowId>

Workflow whose activity transcript is requested.

activity_id: Option<ProtoActivityId>

Activity within the workflow whose transcript is requested.

attempt: u32

Attempt number — the third stream axis. Two attempts of one activity are DISTINCT transcript streams.

after_seq: Option<u64>

Highest store_seq already applied by the client; the server suppresses durable records and live deltas with store_seq <= after_seq so a reconnect does not re-deliver them. Absent (None) = a fresh subscriber that has applied nothing and must see the full durable transcript including store_seq == 0.
