A failed node with an effective `succeed` policy and no explicit recovery
route now finishes as `succeeded` and follows normal success routing. The
original failure stays on the outcome so the stage.completed event and the
checkpoint keep the diagnostic, and the outcome notes record which scope
promoted it.
- OnFailure gains a Succeed variant; Node::on_failure resolves the
deprecated auto_status=true attribute as an alias, with an explicit
on_failure winning
- The core executor applies the policy before the lifecycle observes the
result, so the recorded outcome, context keys, goal gates, events, and
routing all see the effective outcome; this replaces AutoStatusLifecycle
- Explicit routes take priority: a matching condition, preferred label,
suggested next node, or handler jump keeps the outcome failed. A failed
outcome takes an unconditional edge only under route, so under succeed
any edge selection is an explicit route
- succeed applies only to failed, matching exit; the auto_status alias no
longer promotes partially_succeeded
- Parallel branches promote after their retry loop, so a failed succeed
branch counts as succeeded in the parent aggregate
- Validation accepts succeed and adds an auto_status_deprecated warning
that suggests on_failure="succeed"
- Document the policy table, semantics, and deprecation; add a changelog
entry
Closes#807

A node can now set its own on_failure attribute to override the
graph-level failed-node routing policy in either direction: a
best-effort node can keep route inside an exit graph, and a critical
node can exit while the rest of the graph keeps the default. An absent
node attribute inherits the graph policy.
- Node::on_failure returns Option<OnFailure> so absence means inherit
- Graph::resolve_on_failure(node_id) is the single resolution point,
returning ResolvedOnFailure { policy, scope } so the executor's
end-of-run message names the scope that stopped routing
- The core Graph trait method becomes resolve_on_failure(node_id); the
graph-scope failure message is unchanged
- The failed-human-gate fallthrough block stays independent of a
node-level route override
- Validation now accepts and value-checks node-level on_failure (it
previously warned that node placement had no effect) and keeps the
edge-placement warning with updated wording
- Document precedence in transitions, failures, and the DOT reference,
and extend today's changelog entry

- Dedup Diagnostic construction in the on_failure_valid rule
- Use the shared node_with_attrs test helper
- Drop an executor test that duplicated existing retry-target coverage
- Build on_failure integration test graphs from DOT and share a run
harness, exercising the parser path for valid on_failure values

The executor incremented a node's visit count on entry and refused the
visit once the count reached the limit, so a node with max_visits=N
executed at most N-1 times. The documented contract in
stages-and-nodes.mdx is "Max times this node can execute in a run",
and both published examples describe bounded retry loops under that
reading. A graph with max_visits=2 on a designed
one-correction loop therefore failed as "stuck in a cycle" before the
correction could run.
Check the completed-visit count before entry instead: a node with
max_visits=N now executes exactly N times, and the refused entry is
not reported as a visit, so the error's count names the executions
that actually happened. Also correct the nlspec example prose, which
claimed the workflow "moves on with the best result" at the limit;
exceeding max_visits fails the run.
