Product Decisions This Supports

Failure-handling architecture for asynchronous workers. If your product runs background jobs via Symfony Messenger (or a similar worker model), this bundle gives you a structured event hook when a worker message fails — a building block for retries, dead-letter routing, alerting, and user-facing "job failed" status. It informs the build vs. buy call for failure telemetry: adopt this rather than hand-rolling a failure-dispatch layer.
Observability and incident-response roadmap. Failed-message events are the raw signal for dashboards (failure rate by queue), automated retries, and escalation policies. Deciding to standardize on event-bundle patterns like this shapes how much custom instrumentation your team must own.
Ecosystem fit / platform strategy. This is a SmartAssert-family Symfony bundle. Adopting it signals alignment with that ecosystem's conventions; choosing otherwise is a signal you'll maintain your own failure-event contract. Useful input for a "standardize on vendor X vs. internal framework" decision.
Use cases it enables: dead-letter queue tooling, SLA reporting on async pipelines, replay/requeue workflows, and audit trails for failed background operations. It is not a user-facing feature on its own — it is plumbing that makes reliability features cheaper to ship.

When to Consider This Package

You are already on Symfony Messenger and want a first-class failed-message event without writing the dispatcher/event contract yourself.
You are inside or integrating with the SmartAssert ecosystem — the bundle's API and assumptions are designed around it, so fit is highest there.
You need a small, permissively licensed (MIT) dependency and can absorb the maintenance risk of a low-adoption package.
Look elsewhere if: you are on a different queue/worker stack (Laravel Horizon, SQS consumers, custom workers); you need vendor support or SLAs; or your architecture demands a widely battle-tested dependency. With 0 stars, 0 dependents, and a single maintainer lineage, treat it as early / unproven — validate the source, pin versions, and budget for the possibility you fork or replace it. For mainstream needs, prefer Symfony's native Messenger events or a higher-adoption bundle.

To executives: "A small MIT-licensed piece of infrastructure that makes our background jobs fail visibly and recoverably instead of silently. Low cost, low lock-in — but it's niche, so we'd adopt it as an internal helper, not a strategic bet."
To engineering: "It gives us a clean event when a worker message fails — a hook for retries, dead-letter handling, and alerting — instead of bespoke glue code. Caveats: it's tightly coupled to the Symfony/SmartAssert world, has essentially no community adoption, and needs a code review plus version pinning before we depend on it. If we're outside that ecosystem, we should build the equivalent ourselves."
