Every module named its events the way the old bus spelled a routing key — `module.<module>.<verb>`. Design 29 says a module names an event locally and the mesh works out where it lands, so all 37 were stale against a rule already decided. On the new bus that derives into a namespace belonging to a module called "module", so no cross-module subscription in the mesh matched anything: nothing failed, nothing reacted (novox/hq 04-ISSUES/127). 36 manifests converted, and 43 files of module code with them. The code mattered as much as the manifests: the runtime builds the subject from what `emit()` is handed, so a converted manifest with unconverted code would have had the permission and the subject disagree. Three things the new check found on the way: - `photos` emitted an event its manifest never declared, which the new bus refuses outright. Declared. - `showcase` waited for an event nothing emits, so its demo could never be triggered — only `showcase` may publish under its own name. It emits both halves now. - `distribution` declared an event named after a different module. It emits `image.pushed` under its own name. An event about a *role* belongs on the seat, where the name outlives whoever holds it, but the sdk has no way to publish on a seat yet, so that stays recorded rather than declared. The audit logger's "everything" pattern is `**` rather than the old bus's `#`.

// bazarr's events. The tool runtime imports this once the broker is bound. Bazarr's one genuinely
|
|
// observable thing is a subtitle arriving: it works away in the background, searching providers for
|
|
// the missing-subtitle list, and when it succeeds a subtitle appears in its history. That is worth
|
|
// announcing to the mesh.
|
|
//
|
|
// Emits (novox/hq ADR 0041/0042):
|
|
// module.bazarr.subtitle.downloaded — a subtitle was fetched for an episode or movie
|
|
//
|
|
// Bazarr has nothing on the mesh it usefully reacts to (a download completing is Sonarr/Radarr's
|
|
// business, and they trigger Bazarr directly), so it consumes nothing — a pure emitter.
|
|
//
|
|
// The event is observation-based: poll history and diff. Primed silently on the first look, or a
|
|
// restart would re-announce the whole recent history as freshly downloaded.
