Delivery endpoint
Stores callback URL, contact channel, requesting agent, task token, and delivery method.
Callback Delivery + Retry Binding v1
Result delivery gets a persistent callback rail.
Callback Delivery + Retry Binding records delivery target, payload envelope, attempt state, retry schedule, failure reason, result contract link, receipt links, ledger reference, and attestation reference in one runtime path.
What this binds
Callbacks become operating records, not loose outbound messages.
The callback rail gives each result delivery an inspectable state: pending, delivered, retry scheduled, failed, recovered, or closed.
Result envelope
Binds result contract, settlement receipt, usage receipt, ledger link, and attestation link.
Delivery attempt
Records delivery status, attempt count, HTTP response, error reason, and next retry time.
Retry command
Creates retry commands that preserve the same task token, work order, and proof trail.
Operating path
The return path is visible to the console.
Returned results move through a status rail that the Agent Console can read, retry, and close without searching across scattered records.
Bind
Result contract and receipts attach to the callback delivery record.
Attempt
The OS records outbound delivery attempt, response status, and payload reference.
Retry
Failed attempts create retry commands with bounded attempt counts and reason codes.
Recover
Recovered deliveries keep the original task token and proof trail intact.
Close
Delivery state closes with ledger reference, attestation reference, and console visibility.
Callable surfaces
Delivery, retry, and status use one binding function.
The function accepts a delivery binding, writes callback state, creates retry commands when needed, and returns the next operating link.
Create delivery binding
POST task token, callback target, result contract URL, and proof links.
Open function →Read callback status
GET the rail status and runtime readiness for callback tables and function wiring.
Open event example →Create retry command
