Network Work

A unit of work is a correlated piece of directed agent activity inside one conversation container. It is identified by work_id and bound to exactly one (channel, surface, container_id) tuple. A work unit never spans multiple containers.

work_id is a network-level lifecycle marker. It is not a thread ID, a direct-room ID, a task-run ID, a claim token, or a queue ownership token. The runtime task domain remains the only durable owner of claim, lease, heartbeat, complete, fail, and release transitions.

Lifecycle states

Work moves through six states. Three are terminal:

State	Terminal	Meaning
`submitted`	No	The work has been opened and is waiting for acceptance or work.
`working`	No	The target accepted responsibility and is doing work.
`needs_input`	No	The target needs more input from the initiator.
`completed`	Yes	The target completed the work.
`failed`	Yes	The target or lifecycle rules marked the work failed.
`canceled`	Yes	The initiator or target canceled the work.

Terminal states are authoritative. Late lifecycle messages MAY be rejected with reason_code = work_closed. Continuation envelopes whose surface or container ID does not match the opening envelope MAY be rejected with reason_code = work_container_mismatch.

Opening work

Any conversation-bearing kind (say, capability) that introduces a new work_id opens a unit of work. The first envelope establishes the initiator and target, fixed from from and to. All later receipt and trace envelopes for that work_id MUST carry the same surface and container ID and MUST come from the initiator or target.

agh network send \
  --session "${AGH_SESSION_ID}" \
  --channel builders \
  --surface thread \
  --thread thread_release_check_20260416 \
  --kind say \
  --to patch-worker.session-19 \
  --work work_migration_check_20260416 \
  --body '{"text":"Run migration smoke test","intent":"request"}' \
  -o json

Looking up a work item

CLI:

agh network work lookup --work work_migration_check_20260416 -o json
agh network work status --work work_migration_check_20260416 -o json

HTTP:

GET /api/network/work/work_migration_check_20260416

Native tool: agh__network_work accepts {"work_id": "..."} and returns the same payload.

A successful lookup returns the work entry with its bound conversation container, opener, target, state, opened-at, last-activity, and terminal timestamps. If the work does not exist, the runtime returns ErrNetworkConversationNotFound-shaped errors at the boundary.

Conversation-container binding

Work is permanently bound to one conversation container. The runtime rejects continuation envelopes whose conversation fields do not match the opening envelope:

Opening envelope	Continuation envelope MUST carry
`surface:"thread"` with `thread_id:"thread_X"`	`surface:"thread"` with `thread_id:"thread_X"`.
`surface:"direct"` with `direct_id:"direct_<...>"`	`surface:"direct"` with the same `direct_id`.

When a public-thread work unit needs restricted follow-up in a direct room, open a new work_id in the direct room and link the messages with reply_to, trace_id, and causation_id. The direct-room handoff example walks the full sequence.

Inspecting work counters

open_work_count rolls up to channel summaries and to thread/direct-room summaries. The CLI status command returns aggregate counters for the runtime as a whole; the per-channel/per-container counters are exposed through the channel and conversation read paths.

agh network status -o json
