They are neither DOM addEventListener nor a Promise-based message queue.</p><ul><li>on keeps registration order. Registering the same function twice invokes it twice. ctx is passed unchanged as an ordinary function's this; omission means undefined, not an automatic player binding. Arrows retain their lexical this.</li><li>emit synchronously walks a snapshot taken at dispatch start. Added listeners wait until a later dispatch; removed ordinary listeners already in the snapshot still run. Arguments retain their references; callback return values are ignored.</li><li>once removes itself before invoking the callback and prevents nested dispatch from consuming the same registration twice, even if the callback throws. off(name, callback) removes all ordinary/once registrations for that function regardless of ctx; off(name) removes every listener for the name.</li><li>A synchronous throw stops subsequent listeners in that dispatch and propagates through the call stack. Async callbacks are not awaited; handle their failures yourself. The name error has no special Node EventEmitter behavior.</li><li>e is the lazily created registry of fn/ctx records and remains a visible historical interface. A fresh standalone Emitter may not have it yet. Use on/off rather than editing the table. Numeric keys share their string-equivalent channel; symbols have separate keys. The root player's historical overloads accept narrower names than the accurate entry or a generic Emitter.</li></ul><p>Manual emit only sends a notification; it does not replace player methods. Emitting built-in names may also trigger internal listeners. Destruction releases core-owned DOM/internal subscriptions but does not clear every user registration; remove unwanted subscriptions if you retain the instance. The advanced-properties guide explains the separate DOM listener manager, art.events.</p><h2 id="native-event-contract" tabindex="-1">Native forwarding <a class="header-anchor" href="#native-event-contract" aria-label="Permalink to "Native forwarding {#native-event-contract}""></a></h2><p>The default media events below are forwarded with a <code>video:</code> prefix and the original Event object. The browser or proxy determines when they occur:</p><p><code>abort</code>, <code>canplay</code>, <code>canplaythrough</code>, <code>durationchange</code>, <code>emptied</code>, <code>ended</code>, <code>error</code>, <code>loadeddata</code>, <code>loadedmetadata</code>, <code>loadstart</code>, <code>pause</code>, <code>play</code>, <code>playing</code>, <code>progress</code>, <code>ratechange</code>, <code>seeked</code>, <code>seeking</code>, <code>stalled</code>, <code>suspend</code>, <code>timeupdate</code>, <code>volumechange</code>, <code>waiting</code>.</p><p>The <code>video:error</code> argument is not a MediaError or Error instance; inspect <code>art.video.error</code> when needed. Historical types include <code>video:complete</code> and <code>video:encrypted</code>, but neither appears in the default config.events, so the core does not automatically forward them. An adapter must provide forwarding or configure the event inventory before construction. A declared name does not prove an event is produced at runtime.</p><p>Global forwarding uses the player's currently bound document/window and passes the original Event:</p><table tabindex="0"><thead><tr><thLine truncated
