registry (docker v2): catalog/tags/delete tools, emits image.pushed (a build's image is now pullable). verdaccio (npm): list/info tools, emits package.published. portainer: endpoints/stacks/containers tools — tools-only, since its only events are the underlying containers' lifecycle, which the host owns. Typecheck; manifests parse.

// module.verdaccio.package.published — a new package version was published to the registry
|
|
//
|
|
// A genuinely useful signal: a package was just published, so anything on the mesh that pins,
|
|
// mirrors or announces dependency releases can react without polling the registry. Verdaccio has
|
|
// no publish webhook, so the module discovers it by diffing the package list's latest versions.
|
|
//
|
|
// The polling is deliberately unhurried: a publish a minute late is still the event, whereas
|
|
// hammering the registry for immediacy nobody asked for is not.
