feat(flow): Add target-aware hybrid execution dispatch - #5059
Conversation
Summary by CodeRabbit
WalkthroughThe pull request replaces claim-based event execution with pending and deferred results. It adds canonical target resolution, leakage-specific inventory resolution, creation-time deduplication, result-based executor contracts, and processor persistence updates. ChangesEvent rule execution flow
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR changes execution dispatch, retry handling, status persistence, and topology-based power-off targeting. At the current head, interrupted actions can lose their retry path and invalid topology data can select unrelated hardware for power-off, creating concrete availability and hardware-safety risks; merge should wait for these issues to be fixed or explicitly accepted.

76-81: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winA transient target-resolution failure defers with no backoff.
DeferredExecutionResultreceives0asretryAfter. The domain documents a zero delay as immediately eligible, soNextAttemptAtequals the transition time. Every transient inventory failure therefore becomes an instantly due retry. When the inventory dependency is degraded, the future scheduler will re-dispatch these executions in a tight loop and amplify load on the failing dependency.Pass a non-zero delay. A per-execution backoff derived from
Attemptsis preferable to a constant once the attempt counter advances.♻️ Minimal change to introduce a delay

The interruption mapping is now correct. The persistence path is not. When

There was a problem hiding this comment.
CreateExecution persists a pending execution and the creator dispatches it, but nothing recovers that execution if the process exits or TransitionExecution fails between the two writes. RequiresRetryScheduling is true only for deferred, so a pending execution carries no NextAttemptAt for a scheduler to select on, and a redelivery of the same event is absorbed by the delivery key: the store increments Observations and returns (nil, nil), so the action is never dispatched again. For the built-in leak rule that is a silently dropped force power-off.
Either state here that the scheduler also reclaims stale pending executions, or record it as a known gap so closing it is a required part of the scheduler change. In both cases store/storetest/execution_contract.go should cover the sequence where creation succeeds, the transition fails, and the event is redelivered.

This is out of the scope of this PR. There will be a one-time recovery scan which runs during service startup before that instance accepts events or starts its scheduler - it transitions every execution still in pending to deferred which will be process by scheduler later on.
There was a problem hiding this comment.
Thanks — a startup scan that flips pending to deferred before the instance accepts events does close the loss path, and I agree the scan itself belongs in the scheduler change rather than here.
Two things I would still like out of this PR. First, the plan currently lives only in this thread: neither the ExecutionStore contract nor a tracked issue records that pending is recoverable, so whoever implements the Postgres store has no reason not to treat pending as transient. One line on the interface, or an issue link, is enough. Second, helm/charts/nico-flow/values.yaml sets replicas: 1, and that is what makes an unconditional scan safe — above one replica, one instance's startup scan would also flip rows a live peer is mid-dispatch. That is survivable given the Execution.ID idempotency requirement already documented on Executor.Execute, but it is a premise the scan depends on and worth stating so it is not rediscovered later.

There was a problem hiding this comment.
ExecutionRequest.Validate checks the execution, the action, and every target, but nothing calls it before Execute. Registry.Resolve validates the targets it returns, and Config.Targets accepts any target.Resolver, so a resolver outside the registry can hand a nil target ID or an unsupported kind to an executor that performs side effects.
There was a problem hiding this comment.
We don't need to call the ExecutionRequest.Validate here since all the information should be validated already. The Validate() can be used by other callers to Execute(), but not here. Why do we have a resolver outside the registry? If there is one, it is the resolver's responsibility to return validated result.
There was a problem hiding this comment.
Fair enough on not validating here. To answer the question directly: a resolver outside the registry is possible because Config.Targets is typed as the target.Resolver interface, so nothing structurally restricts it to the registry — the guarantee you are relying on is a convention, not a type.
If registry-only is the intent, narrowing that field to *target.Registry expresses it in the type and makes the guarantee real, which seems better than either validating again here or leaving it to convention. If the interface is deliberate because the scheduler will supply its own resolver, that works too, but then it would help to name the intended caller of ExecutionRequest.Validate, since it has none today.

Fair enough on not validating here. To answer the question directly: a resolver outside the registry is possible because Config.Targets is typed as the target.Resolver interface, so nothing structurally restricts it to the registry — the guarantee you are relying on is a convention, not a type.
If registry-only is the intent, narrowing that field to *target.Registry expresses it in the type and makes the guarantee real, which seems better than either validating again here or leaving it to convention. If the interface is deliberate because the scheduler will supply its own resolver, that works too, but then it would help to name the intended caller of ExecutionRequest.Validate, since it has none today.

Deduplication seems ignoring the matched execution's status.
TryDeduplicate only checks the window, so an observation is absorbed even when the execution it matches has already reached a terminal status. If the first execution for a correlation key ends in failed — a terminal target-resolution error, or an executor contract failure — every redelivery inside Dedupe.Window increments Observations and returns (nil, nil) from CreateExecution, and no new execution is created. The built-in leak rule's action is a force power-off, so the observable behavior is that a permanently failed power-off suppresses the next report of the same leak for the remainder of the window.
Is that intended? Anchoring the window at CreatedAt reads correctly while an execution is pending, deferred, or submitted, because each of those still has an outcome coming. A terminal failed has none, and treating a repeat report as its duplicate discards the signal that would drive a fresh attempt.

There was a problem hiding this comment.
For a component-scoped leak the resolver does real topology work: affectedComponentIDs locates the source slot and returns the source plus the components below it. The ResourceKindRack branch returns a single rack target and skips that reasoning, so "affected" degrades from a computed subset to everything, with DefaultRule's force_power_off behind it. That is the widest possible response to the leak whose location was reported least precisely.
Also cannot tell from the tree what a rack target means downstream: internal/task/common carries no scope distinction between rack and component targets, and nothing in production consumes []target.Target yet. So whether a rack-scoped force power-off cuts the rack chassis, iterates its components, or reaches the power shelves is not answerable from this change.
Stating the intended semantics here would settle it — either a rack-scoped leak is deliberately a whole-rack response because the report carries no position, or it should expand to the rack's components so the same topology rules apply to both kinds.

Leakage detection currently polls NICo Core for leaking information and
immediately submits a force power-off task for each affected component.
That is safe as an initial behavior, but it hard-codes both detection
and response in the leak detection job.
We need a pre-defined response at startup, while leaving room for users
to define their own rules later. And the mode should be reusable for
other event families such as thermal alarms, inventory drift, firmware
health events, attestation failures, etc.
We plan to create event rules which decide what to do in response to an
event.
This PR replaces claim-based execution ownership with atomic execution
creation and deduplication. The creator dispatches only a newly created
execution, while duplicate observations do not dispatch and deferred retry
ownership remains with the future scheduler.
