Struct AgentCommitPrimaryRequest 

pub struct AgentCommitPrimaryRequest {
    pub primary_cf: u32,
    pub primary_key: Vec<u8>,
    pub fence: u64,
    pub commit_ts: u64,
    pub participants: Vec<CrossShardTxnWrite>,
    pub start_ts: u64,
}

The commit point: CAS the primary TxnStatus Prewritten->Committed at commit_ts, gated IfSeqEquals(fence). A coordinator that lost its lease (the per-key seq advanced past fence) is rejected (#784/#894).

Fields

primary_cf: u32

CF of the primary key

primary_key: Vec<u8>

the txn’s primary key (holds the single commit point)

fence: u64

primary claim’s fencing token (gates the CAS)

commit_ts: u64

HLC commit_ts (packed u64)

participants: Vec<CrossShardTxnWrite>

The participants (cf, key, delete-op) the txn prewrote, recorded on the status so a resolver can finish any secondary the coordinator didn’t roll forward — each participant’s delete flag records its op so the resolver can decide put-vs-tombstone without consulting the (possibly reaped) lock (#1626).

start_ts: u64

The txn’s HLC start_ts (packed u64), recorded so a resolver can locate each participant’s staged value after the prewrite lock TTL-expired (#1626).
