The queue carried a per-DAG `HookKind` that fired an inline side effect
from outside the graph when a container rolled up terminal. mara asked
three times why this could not be an ordinary node; the answer in the
code was a doc-comment claiming a node could not work, and it was wrong.
`DepWhen::AfterAny` already existed with two live users, and a weak edge
is satisfied by a `Cancelled` dep, so a tail node runs on success,
failure and cancel alike. What was genuinely missing was smaller than a
hook: a node had no way to learn how the work it followed ended.
So: `Claim` now carries `deps: Vec<DepOutcome>`, snapshotted at claim
time from the graph the scheduler already holds (no `hive-jobq` change).
`Claim::deps_state()` / `deps_error()` roll that up, and two new kinds
consume it — `ResolveApproval { approval_id }` and `EmitRebuilt { agent }`.
Templates append one as a group-root with `AfterAny` edges onto the DAG's
other group roots; a root's state is its subtree's roll-up, so that
covers every node without fanning out to each of them.
Deleted: `HookKind`, `DagSpec.hook`, `NodeKind::Dag.hook`, `DagMeta.hook`,
`TerminalDag`, `terminal_dag()`, `terminal_summary()`, `dag_agents()`,
`dag_rollup()`, `fire_terminal_hook()`, `run_terminal_hook()`,
`emit_rebuilt()`. `complete_node` returns `()`.
Load-bearing details:
- `JobQueue::cancel` spares tail nodes instead of cancelling the whole
subtree, and returns `bool`. Without this a cancelled approval DAG
would dangle its approval forever — the hazard `tests.rs` already
named. The spared tail's deps are `Cancelled`, which satisfies its weak
edge, so the scheduler claims it and it resolves the row as cancelled.
`hive-jobq` anticipated exactly this: `cancel_node`'s doc already says
to settle afterwards so "a weak-edge terminal node observing the
cancellation" can advance.
- The existing `complete(container)` call after cancelling is kept and is
deliberately a no-op when a tail was spared (a non-terminal child parks
the container back in `Finishing`), so power ops still settle
synchronously with no branch.
- `DeployTail` is NOT `is_tail()`: it does real compensating work, and a
cancelled DAG has nothing to compensate.
- `exec::failure_reason` falls back to `first_error(dag_id)` because a
group root that rolled up `Failed` from a child carries no error of its
own — without it every tail-reported failure would lose its reason.
- `EmitRebuilt` is per agent, so a multi-agent DAG reports each agent's
own outcome rather than painting all of them with the DAG roll-up.
- `ResolveApproval` is agentless: the approval row already names its
agent, and that is also what lets one tail close a multi-agent DAG.
Transients-derived-from-running-nodes and the frontend's node-kind
strings stay out of this change; they touch iris's slice and review
better next to their own diff.
jobs are now DAGs of primitive nodes (prebuild, stop-for-update, swap,
reconcile, signal, drain, ...) driven by one scheduler with N build
slots + per-agent lifecycle leases. per-agent power intent (wanted
up/offline) is durable in agent_power.sqlite; Reconcile nodes converge
observed state to it. kills the graceful-stop watcher thread, the
deferred-start follow-up, and the cascade pre-enqueue (fan-out on
MetaLock completion instead). tracker: #2166
Replace brittle msg.contains("not found") string matching in
post_schedule_pause / post_schedule_resume with a typed
ScheduleNotFoundOrCancelled error that handlers downcast on directly.
pause() and resume() now return Err(ScheduleNotFoundOrCancelled(id).into())
instead of bail!("schedule {id} not found or is cancelled"); handlers call
e.downcast_ref::<ScheduleNotFoundOrCancelled>().is_some() for the 404 branch,
making the discrimination stable even if the error message wording changes.
Adds pause/resume support for scheduled prompts.
Backend:
- New paused_at_unix column on scheduled_prompts table (added via
ALTER TABLE migration so existing databases are upgraded on first
start). The due-rows index is dropped and recreated to also exclude
paused rows so the worker never fires them while paused.
- Worker's due() query gains AND paused_at_unix IS NULL filter.
- New pause(id) and resume(id) methods on ScheduledPrompts; both are
idempotent and refuse cancelled rows.
- New POST /api/schedules/{id}/pause and /api/schedules/{id}/resume
dashboard endpoints (operator-direct, no approval gate). Both emit
a schedules snapshot on success so the tab updates live.
- WireSchedule gains paused_at_unix: Option<i64> so the frontend can
render the state without an extra fetch.
Frontend:
- Paused rows render with a distinct row class + muted opacity.
- The next-fire cell shows a yellow pause glyph + tooltip with the
paused-since timestamp and the would-have-fired time.
- Actions column: pause/resume toggle button (⏸/▶) beside fire/edit/cancel.
Fire-now is disabled while paused (resume first).
- Sort order: active → paused → cancelled (paused slot keeps schedules
visible without mixing them into the active top section).
- pauseSchedule() / resumeSchedule() async functions POST to the new
endpoints and refresh the table on success.
The per-agent and manager sockets ran two parallel dispatchers with
duplicated lifecycle handlers (agent-side topology-gated, manager-side
ungated) plus a manager-only handler set. Collapse to one parameterized
server in socket_server.rs:
- one serve() + dispatch(req, agent, privileged, coord); start() binds
the per-agent sockets (privileged=false), start_manager() binds the
manager socket (privileged=true).
- each lifecycle/config handler (start/restart/kill/update/init_config/
apply_commit) merges its dual: the topology guard (require_child /
require_new_child) runs only on the !privileged path; init_config
records the requester as parent only when !privileged. restart keeps
the orthogonal, capability-gated + audited infra-container branch.
- the agent-state queries (loose-ends / reminder count + rollup) branch
on privileged: privileged keeps any-target + the "*" hive-wide sweep
(query_agent_state-gated), non-privileged keeps the topology/cap gate.
- the privileged-only verbs (schedules / meta-inputs / get_logs) plus
the submit/schedule/watchdog helpers move into socket_server; they are
reached via dispatch_privileged_only(), which rejects the whole group
on a non-privileged socket.
- delete manager_server.rs; repoint refs; merge the test modules.
No behavior change: the topology guard still applies on every
non-privileged lifecycle call, the privileged socket still acts on any
agent, and privileged-only verbs are still rejected on agent sockets.
